Home Alone, Part Twelve

Summary: Caroline and Rebecca make sure Riley has a birthday she’ll never forget

Riley started awake as someone else’s body weight settled onto the bed beside her. An arm was thrown around her and she found herself being spooned by a warm body. She smiled, thinking it had to be Rebecca. The smile widened when she thought it could even be Caroline, having come in through the window.

Her new bedmate didn’t say anything for a long moment, and curiosity was getting to Riley. It stretched until she couldn’t take the anticipation anymore. She was about to say something when the girl finally spoke.

“You awake, Birthday Girl,” Rebecca asked, kissing her just behind her ear. It sent a shiver down Riley’s spine.

“I am now,” Riley said, grinning, “what time is it?”

“About six-forty,” Rebecca said, kissing her shoulder at the base of her neck.

Rolling to face her step-sister, Riley asked, “What are you doing up so early?”

Rebecca gave her a playful smile, said, “Just wanted to get you in the right frame of mind for tonight.”

“Oh,” Riley asked, grinning, “and what does that mean, exactly?”

“Just this,” Rebecca said, kissing her deeply. Riley felt herself responding to Rebecca’s kiss, the first flush of excitement overcoming her.

When their lips finally parted, Riley said, “Wow!”

“Take your panties off,” Rebecca said, smiling playfully at her.

Riley had to swallow hard at the look in her stepsister’s eyes. Her hands were shaking as she slipped out of her panties in a hurry. She tossed them aside as Rebecca got to her hands and knees. The teenager spread Riley’s legs wide, moving between them. The gentle kisses she placed on Riley’s girlhood sent a shivers up her spine. They were as light as the brushes of a butterfly’s wing against her very sensitive flesh. Then Rebecca’s hot tongue caressed her bud, drawing a moan from her.

She bit her lip to keep quiet as Rebecca’s mouth made her lose control of her body. The wonderful things her step-sister was doing to her made it nearly impossible to hold in the little sounds of enjoyment she was making.

The hot, wet caress of Rebecca’s tongue had her hips undulating against her mouth, and Riley could see her cheeks getting wet from her thrashings. Rebecca’s fingers dug into her thighs as the teenager tried to keep her mouth to Riley’s bud. The pain couldn’t distract her from the waves of pleasure washing over her.

Rebecca’s hand slipped from her thighs and under her shirt. Riley groaned as they found her breasts, kneaded them. Her back arched off the bed, as the teenager teased her straining nipples until they ached sweetly.

Already she felt tension creeping into her body. Rebecca just seemed to know what her body wanted, her mouth making Riley writhe in ecstasy. That tension built upon itself, coiling tighter and tighter deep inside Riley’s young body. Like a watch spring wound too tight, that tension finally became too much, and she hissed through clench teeth as her body locked up with an orgasm. The explosion of pleasure shook her loose, and she was left trembling all over.

The endorphins flooded her bloodstream, and she felt as light as a feather on a summer breeze, just floating down from on high. It took a moment for her toes to uncurl and her heart to stop racing like a jackrabbit on methamphetamines.

“Jesus,” Riley said, laughing breathlessly, “now that is how to wake up in the morning.”

Grinning, Rebecca wiped her mouth with the back of her hand, then gave Riley a quick kiss. Getting off the bed, the teenager said, “I better go. Your dad should be getting up for work soon. Wouldn’t do either of us any good if he caught me sneaking out of your room.”

“No, it wouldn’t,” Riley said, laughing, “especially since you are half naked. You could have at least put some shorts on.”

Looking down at herself, Rebecca said, “I had to put the shirt and panties on as it is.”

Laughing, Riley said, “You sleep naked, right.”

Rebecca winked at her, then eased the bedroom door open just a crack. She peered out into the hallway for a second. Then she was gone, leaving Riley to smile after her. Shaking her head, she couldn’t help but laugh.

Glancing at her alarm clock, she saw it was about twenty minutes until it was set to go off. It’d be a waste of time trying to get back to sleep in that short amount of time, so she rolled over and turned it off. Rolling onto her back, she stared up at the ceiling and wondered what Caroline and Rebecca had in store for her.

Either one of them knew how to drive her wild but the two of them together…

Riley shivered at the thought, giggling excitedly. It could be a very interesting evening.

—————————————-

Riley looked down at the sad excuse for meatloaf on her tray, grimacing. She knew from experience that not even the too salty gravy could mask the weird after taste of the mystery meat. Staring at the curiously gray meat, she thought if she followed each bite with a healthy swallow of milk, she might be able to choke down a few bites.

“Are you really planning on eating that,” Caroline said, sitting down across from her.

“Hey,” Riley said, smiling at her. The smile slipped when she looked down at her tray, again. She pushed it aside, untouched.

Caroline gave her a playful smile, said, “Come on.”

“Where are we going,” Riley asked.

“Just dump that,” Caroline said, standing up, “I have something better.”

“You do,” she asked, surprised.

“Yeah,” Caroline said with that same playful smile tugging at the corners of her mouth.

Intrigued, Riley dumped her tray and followed her girlfriend. She figured Caroline must have something in her locker, but they walked right past it. She looked over her shoulder at the locker, frowning.

“Where are we going,” Riley asked, turning back around.

“You’ll see,” Caroline said.

Riley narrowed her eyes. She knew that tone of voice. Caroline was up to something. Just what, Riley didn’t know, but definitely up to something.

Caroline led them to the far end of the school, finally stopping at a door with a sign that read ‘Storage B’. Raising her eyebrows, Riley looked expectantly at Caroline. Her girlfriend just winked at and produced her student idea from her pocket. With a quick look around, she slipped the stiff plastic rectangle between the door and the jam. She jimmied it up until the door popped open. One more look around and Caroline grabbed Riley’s hand and pulled her into the dark room.

“What the-” Riley said, laughing.

“Just a second. The switch is right around-” Caroline said, and then a low wattage overhead light came on, “got it!”

Riley’s eyes widened as she looked around. Along the three walls that didn’t have a door were rows of desks, roll away chalkboards, projectors and other relics of years past. It was a curiosity, a little look into the past of the school, but it wasn’t what made her gasp in surprise.

In the center of the room, a blanket had been spread out on the floor, and the making of a picnic laid out atop it. Riley started laughing, then pulled Caroline against her for a kiss. Her arm still around her girlfriend, she looked at the spread, grinning.

“You did all this,” Riley asked, looking at her.

Caroline smiled and nodded.

“This is,” Riley said, looking for the words, “pretty awesome.”

“I’m glad you like it,” Caroline said, kissing her, again, “let’s eat.”

They sat on the blanket, Riley snuggling close to Caroline. She couldn’t believe the girl had pulled this off. How she had smuggled all of this into the school, then into this old storage room was a wonder. The fact that she had gone to all the trouble for her made Riley feel warm all over.

“This really is amazing, Caroline,” Riley said, meeting her eyes. Caroline gave her a warm smile, then kissed her deeply. The food was forgotten for a long moment as they got lost in the kiss. They were smiling at each other when their lips finally parted.

“Never made out at school before,” Riley said, laughing.

“Beats math class,” Caroline said, picking up one of the sandwiches.

“You’ve made out in math class,” Riley teased, drawing a look from the girl.

“Smartass,” Caroline said.

Riley tried one of the sandwiches and sighed happily. It was delicious, so much better than the meatloaf she was trying to psych herself up for eating. Caroline produced a can of Coke, past it to her, then opened one for herself.

“A Coke and breaking into a storage room,” Riley said, grinning, “you are a wild woman.”

“You have no idea,” Caroline said, taking a big swig of her drink. She flashed her braces at Riley.

Laughing, Riley just shook her head. God, she loved this girl.

They ate in silence for awhile, not really needing to talk. The sandwiches were made short work off; then they split a package of Hostess cupcakes. It was the best meal Riley had ever had at school, and it was only partly because of the quality of the food.

The used sandwich bags and snack cake wrappers were stuffed back in a backpack Riley hadn’t noticed before. The empty soda cans joined the rest of the trash. The blanket would probably be folded up and stuffed into the book bag, too, but they weren’t quite finished with it, yet.

Riley bit her lip and flashed her eyes at Caroline, then leaned in for a sugary kiss. Putting her arms around the girl’s neck, she said, “Thank you. This was… Wonderful.”

“I wanted to do something special,” Caroline said.

“Oh, it was,” Riley said, smiling warmly at her, “I’ve got to ask… How did you know about this place?”

“Someone might have suggested it to me,” Caroline said, grinning.

“What? Who-” Riley started to ask, then had to laugh, “Rebecca, right?”

“She used to skip class and hide in here when she went to this school,” Caroline said.

“Sounds about right,” Riley said, laughing, “you know, she woke me up this morning. Crawled into bed and gave me a very spirited wake-up.”

Laughing, Caroline said, “I know.”

“You know,” Riley parroted, her eyes widening.

“She called and asked permission, said since we were dating now, she thought she should ask first,” Caroline said.

“And you gave her permission,” Riley asked, her eyes widening.

“Is that weird,” Caroline asked.

“Probably,” Riley said, laughing, “then again, our relationship is less than conventional.”

Shrugging, but not carelessly, Caroline said, “I figured, with what we have planned for the tonight, it didn’t seem like that big of a deal.”

“You are officially the coolest girlfriend ever,” Riley said, kissing her. The kiss deepened in a hurry and desire welled up inside of Riley. She broke the kiss and looked into Caroline’s eyes, saw the girl was feeling it, too. Her eyes went to the closed door, and she bit her lip. An idea started to take root in her mind.

Caroline followed her eyes and she was grinning when she looked at Riley, “It’s locked. No one comes in here. Not even the janitor.”

Riley looked around at the thick layer of dust on everything and thought Caroline was probably right about no one coming in here. There was still a chance they could get caught but that only added to the excitement. Her heart beat a little faster as she found herself contemplating the idea.

Putting her hand on Riley’s knee, Caroline leaned in and kissed her. As their tongues caressed and teased each, that hand moved higher on Riley’s thigh. With an inward smile, Riley knew what her girlfriend was up to, but she didn’t want her to stop. Her own hand came up to cup one of Caroline’s pliant breasts through her shirt.

Pulling back, Caroline said, “We aren’t going to our next period class, are we?”

Grinning, Riley shook her head. She urged the girl to lay down with her, and Caroline didn’t put up much of a fight. The space between them evaporated, their young bodies molding together. Looking at each other, they started giggling. Then kissing. The kissing led to touching, which led to more giggling.

“I can’t believe we are doing this at school,” Riley said.

The first bell signaling the end of the period rang and Riley and Caroline looked at each other. Seven minutes from now, a second bell would ring, and they would be officially skipping class. Caroline started grinning first, then Riley let a giggle slip free, and then they were both rolling on the floor, laughing. They ended up in each other’s arms, and they were kissing as the second bell rang.

“Uh oh,” Riley said, grinning at her girlfriend.

Grinning back at her, Caroline said, “Looks like we have an hour to kill. What should we do?”

“I could think of a few things,” Riley said, kissing her, again.

Riley moved atop her, straddling her hips. She pushed Caroline’s skirt up around her hips, then bunched up her own skirt. Caroline saw her intentions, grinned up at her. Leaning down for a quick kiss, Riley moved so their bodies were nested together. Riley still loved how their bodies fit together like they were meant for each other. She was the yin to Caroline’s yang, the jelly to her peanut butter.

Even through the cotton panties she wore, their bodies rubbing together was doing wonderful things to Riley. She rolled her hips back and forth, really grinding against her girlfriend. Caroline’s hands were on her hips, encouraging her. She had to bite her lip as the first moan wanted to escape. Caroline grinned up at her and put her finger to her lips in the universal keep quiet sign.

Easier said than done, Riley thought, leaning down to kiss the girl.

Looking down, Riley saw Caroline’s fingers messing with the buttons on her shirt, already had three of them unbuttoned. Caroline was grinning as she pushed one shoulder down, revealing her breast. Her hand slid up Caroline’s arm, over her shoulder and down to cup her breast through the bra she wore. Groaning as the girl teased her straining nipple, Riley cast a glance over her shoulder at the door. When she looked back, she saw Caroline fumbling with the catches in the front of her bra. It fell open, and her hand was on Riley’s bare skin.

“Do think that is a good idea,” Riley said, around a moan.

Caroline’s hand slip from her breast and she resumed unbuttoning Riley’s shirt, and she said, “Oh, it’s a horrible idea.”

Laughing, Riley shrugged out of her shirt, then her bra. She couldn’t contain the nervous giggle from being naked from the waist up in school. Looking at the door, again, she sent up a little prayer to the god of kinky school sex and asked that it not open anytime soon.

Caroline’s eyes were hot on her bare skin and Riley looked back at the girl, saw the smile tugging at the corners of her mouth. She loved the way the girl looked at her, the desire in her eyes. Caroline made her feel beautiful, the way she looked at her. Sexy.

Grinning down at the girl, Riley started unbuttoning Caroline’s shirt. She didn’t want to be the only one busted without her shirt on. That and she loved Caroline’s young body, wanted to see more of it. The movement of her hips came to a halt so she could focus on the tricky little buttons on the top. When the shirt fell open, she popped the catches on Caroline’s bra. Riley ran her hands over Caroline’s taut stomach, up to cup her small breasts. She could feel Caroline’s nipples straining against her palms, teased a moan from the girl.

Caroline’s fingers were in the waistband of Riley’s skirt, trying to pop the buttons. Riley looked down at them, then met the girl’s eyes and said, “Just how far are we going to strip?”

Grinning up at her, Caroline said, “I’ll let you keep your socks and shoes.”

“God, this is such a bad idea,” Riley said, helping the girl with the skirt. It fell open, draped across Caroline’s knees behind her. Getting to her feet, she ran her panties down her long legs, then stepped out of them. Naked save for her socks and shoes, she looked down at Caroline, saw the girl busy removing her own clothes. She watched her shrug out of her open blouse and bra, then work the buttons on her skirt. Finally, she shimmied out of her panties, slipped out of them and tossed them aside.

Grinning at Riley, Caroline said, “What are you doing way up there.”

Riley laughed and stretched out beside her girlfriend. The space between them evaporated as their lips met. Their kiss was punctuated here and there with excited giggles. They couldn’t keep their hands off each other.

It was Caroline who rolled on top of Riley, this time. Riley smiled as her weight settled atop her and she wrapped her legs around the girl to keep her there. Stroking her hair lovingly, Riley kissed her deeply as the girl began to rub against her. With no cotton panties to dull the sensation, the meeting of their bodies forced a moan from Riley.

They found an easy rhythm, Riley pushing up into Caroline’s thrusts. They took their time, enjoying the closeness of each other’s body. Hands restlessly explored the other’s body, found them fascinating. The dusty storage room seemed to push back and disappear until Riley’s everything was Caroline’s soft skin, the warmth of her body, the scent of her soap and the musky smell of their lovemaking, the warm breath on her neck as Caroline began to breathe heavily. She lost herself in the feel of the girl moving against her, everything else forgotten. It was just her and Caroline and nothing else.

Riley heard Caroline’s little murmured cries grow more urgent, felt tension enter her girlfriend’s body and knew she was about to come. It was okay, though. Riley was right there with her, her own orgasm swelling to meet the one gathering force in Caroline. Their eyes met and, in that intimate moment, they both climaxed hard, their little cries of ecstasy in perfect harmony. They shook together until all the tension left their young bodies. As limp as a wet rag, Caroline collapsed atop Riley, and she held her tight.

Eventually, their surrounding came back into focus, and they remembered where they were. Looking at the door, Riley hoped they had been quiet. She didn’t know, had been so wrapped up in being with Caroline that she could only hope.

“Babe, that was amazing,” Caroline said, rolling off of Riley.

Grinning, Riley said, “Babe?”

Caroline knew why Riley was amused, said, “I don’t know. It just slipped out.”

Cuddling against the girl, Riley asked, “Does that mean you are ready for pet names, now?”

“I guess I am,” Caroline said, grinning at her, “I love you.”

“I love you, too.”

“As much as I hate to say it, I think we should probably get dressed,” Caroline said, her own eyes going to the door, “I think we’ve pushed our luck about as far as we should.”

With a dramatic sigh, Riley said, “I guess.”

They hurriedly got dressed. Modesty restored, they packed up the blanket, made a quick sweep of the place. Satisfied, Riley pulled Caroline into her arms and kissed her deeply. Pulling back, she grinned at the girl and said, “I can’t believe we did it at school.”

“I know, right,” Caroline said, grinning, “I can’t wait to do it, again.”

“Well, we have all night tonight.”

“I meant at school,” Caroline said.

“Oh my,” Riley said, laughing.

The bell rang, making them jump. Caroline grabbed the backpack with the debris from their lunch, went to the door. She opened it, peeked out into the hallway. Nodding, she motioned Riley out into the hallway. They made it out and closed the door before people started filling the hallway. No one noticed them.

Caroline grinned at Riley, said, “Until tonight, Love.”

“Until tonight.”

They went their separate ways, their lockers in opposite directions.

Riley opened her locker, started getting the books for her next class. She smiled when Allie stepped up to the locker beside her. Allie gave her a curious look, then put her combination into her lock.

“You weren’t in class,” she said, opening her locker.

“Um, no,” Riley said, feeling her face turn red, “something came up.”

“What did you do, cut class to make out with Caroline,” Allie teased, then her eyes widened when she heard Riley gasp, “Oh my fucking God, you did!”

“Keep it down, would you,” Riley said, looking around. Luckily, no one seemed to have heard her. She relaxed a little, then gave Allie a sheepish grin, “Sorry.”

“No, it’s my bad. Got a little excited there,” Allie said, then leaned in and whispered, “so you really did it? At school?”

Taking a deep breath that she let out in a nervous giggle, Riley said, “Yeah.”

“You slut,” Allie said, grinning.

“Hey,” Riley laughed, pretending to be offended.

“I’m jelly,” Allie said, laughing, “I still haven’t found a fuck buddy, yet. Well, not in real life. Been talking to Caroline’s friend, Natty, online. Now that girl is something else.”

Riley snorted in surprise, then just shook her head. She thought Caroline would probably agree with Allie’s description of Natty. Then she wondered if Caroline and Natty still did the cyber nasty. She made a mental note to ask her later.

—————————————-

Riley was sitting on the couch in the living room, some sitcom on the television she really wasn’t watching. If asked, she couldn’t even tell what the premise of the episode was. Mostly she was watching the agonizingly slow sweep of the second hand on the grandfather clock in the corner. Each tick seemed to take minutes and each minute hours. The wait for her parents to leave for date night was dragging out, and the anticipation was killing her.

“Hey, Kiddo,” her father said, sitting down beside her on the couch.

Riley glanced at him, her heart starting to race seeing him wearing his coat. It must almost be time. She tried to keep her excitement off her face as she smiled at him, but she wasn’t sure how good a job she was doing.

“Hi, Dad,” she said.

“Since Rebecca is in for the night, we are going to be late getting home,” he said.

“Um, okay,” she said, fighting the urge to get up and pump her fist in victory.

“Are you excited about your birthday,” he asked, smiling at her.

“Yeah,” she said, thinking she meant it in a different way than he did. It wasn’t presents or cake that had her grinning but two sexy girls who’d be sharing her bed very soon.

“Thirteen,” he said, shaking his head sadly, “I’m not sure I’m ready to have two teenage girls in the house. Rebecca is already a handful.”

Laughing, Riley said, “You’ve got a week to get ready.”

“Get ready for what,” her stepmother said, coming into the living room. She had her coat on, as well, and looked ready to go.

“Having two teenage girls in the house,” Riley said, grinning at her.

“Yeah,” her stepmother said, sighing, “I’ve been stocking up the liquor cabinet.”

“Hey,” Riley said, laughing.

“I’m teasing, of course,” she said, smiling at Riley, “you are becoming a lovely, mature young woman. Your father and I are proud of you; how you’ve behaved being left home alone.”

“Um, thanks,” she said, with an inward grin. She thought, if they only knew…

“Let’s go, Honey,” her stepmother said.

“Okay,” he said, patting Riley on the knee, “don’t give Rebecca too much trouble.”

“I won’t,” she said.

Riley forced herself not to watch them leave, to keep her eyes on the TV screen. She was holding her breath, but there wasn’t anything she could do about that. She let it out in an excited giggle as she heard the front door close with a click. When she heard the car start in the driveway, she couldn’t sit still anymore. She had to get up and move around.

She heard the car shift into gear and knew her father was backing out of the driveway. She pulled out her phone and dialed Caroline.

The girl answered on the first ring, said, “I’m on the way.”

Laughing, Riley said, “Okay.”

Caroline had already hung up. She put her phone back in her pocket, went to the front door. Counting to ten, she opened it. Stepping onto the stoop, she saw Caroline running down the street. Laughing, she stepped back inside. Then Caroline was in her arms, and the door was closed. Riley found herself pressed against the front door, pinned. Caroline kissed her deeply, and she was glad for the door as her knees grew weak.

Finally breaking the kiss, Caroline said, “Hi.”

Riley laughed and said, “Hi.”

“That was the longest afternoon, ever,” Caroline said, grinning at her.

“Tell me about it,” she said.

“Are two starting without me?”

Riley looked past Caroline and saw Rebecca coming down the stairs. Her eyes widened when she saw what she was wearing. Or wasn’t wearing, as the case would be. Her long legs were sheathed in nylons that were attached to a lacy garter belt on her hips and that was all she had on.

“Wouldn’t think of it,” Caroline said, grinning at her over her shoulder. Like Riley, she stopped to gape at the teenager. Finally, she managed to say, “Holy shit!”

“You all are wearing way too much clothing,” Rebecca said, coming up beside them.

“Well,” Caroline said, laughing, “I just got here.”

“I left you something in the bathroom,” Rebecca said, winking at Caroline.

“What,” Caroline asked, raising her eyebrows questioningly.

“Why don’t you go see,” Rebecca said.

“Um, okay,” the girl said, shrugging.

“We’ll be in Riley’s room,” the teenager said.

Grinning, Caroline said, “You aren’t starting without me, are you?”

Rebecca laughed and said, “Wouldn’t think of it.”

Caroline headed upstairs to the bathroom, leaving Rebecca and Riley to watch her go. Grinning, Rebecca turned back to Riley and said, “You are welcome.”

“What,” Riley asked, looking at her stepsister for an explanation.

Still grinning, she said, “You’ll see.”

“Okay,” Riley said, giving her a curious look.

“Come on,” Rebecca said, putting an arm around her shoulder, “let’s get you naked.”

Laughing, Riley let her stepsister lead her upstairs. In her room, Rebecca started undressing her, pulling her shirt up and over her head. It was tossed aside, then her bra followed suit. Rebecca was grinning at her as she unbuttoned Riley’s jeans and worked the zipper down. Riley helped her worked the pants off her hips, then down her legs. Her panties didn’t last long, and Riley found herself standing very naked in the middle of her room.

“I have something for you, Birthday Girl,” Rebecca said, taking something off the bed.

Riley laughed when she saw the pointy paper hat that said, ‘Birthday Girl’ on the front. Rebecca put it on her head cockeyed, then fitted the elastic strap under her chin.

“Not as sexy as your outfit,” Riley said, looking at her reflection in the mirror. She looked ridiculous.

“I don’t know,” Rebecca said, grinning at her, “I think you look pretty good.”

“Nice hat.”

Riley turned to see Caroline standing just inside the door. Her heart skipped a few beats seeing her standing there. She blinked a few times, making sure she wasn’t seeing things. Caroline saw her stunned look, started grinning. She did a slow spin for Riley.

Somehow, her girlfriend seemed to be wearing a white bustier with black lace trim and black lace panels; white stockings with lace tops that matched the top; and a tiny thong. A black ribbon choker finished off the sexy outfit. It clung to her young body in all the right places and made Riley’s jaw hit the floor.

“You look amazing,” Rebecca said, grinning.

Riley couldn’t find her voice, so she just nodded her agreement.

“Where on earth did you get this,” Caroline said, looking down at herself.

“Found it on a website out of China,” Rebecca said, then added, “I had to guess your measurements.”

“It fits perfectly. How can that be?”

“Their sizes are a lot smaller than US sizes,” Rebecca said, then grinned, “You wear a small in Asian sizes.”

Laughing, Caroline said, “Good to know.”

Riley finally found her voice and said, “I can’t believe how hot you look.”

“Thanks, Love,” Caroline said, smiling warmly at her.

“I bought you something, too,” Rebecca said, and Riley looked at her. Grinning, she said, “I’ll give it to you later. You probably won’t need it tonight.”

“Yeah, you get to be the monkey in the middle,” Caroline said, winking at her.

“Monkey in the middle,” Riley asked, raising her eyebrows questioningly.

“A game Natty and her friends play,” Caroline said, moving closer to her, “Don’t worry. You’ll like this game.”

Wrapping her arms around Riley’s neck, Caroline kissed her deeply. Riley kissed her back, put her arms around her waist and pulled the girl close. Rebecca moved behind her, and Riley found herself sandwiched between them. Grinning, Riley thought she knew what Caroline had been talking about when she said ‘monkey in the middle’.

Caroline broke the kiss and grinned at her. That grin got to Riley, and she felt her heart start racing. Then Caroline sank to her knees in front of her and looked up at her with that grin still tugging at the corners of her mouth. She ran her hands over Riley’s legs, all the way up to her hips. Caroline leaned forward, kissed the inside of one thigh, then the other. Riley shivered as the girl’s lips found her girlhood, then sighed as her tongue teased her bud.

Her attention had been on Caroline, but Rebecca wasn’t going to be forgotten. Her hands slipped around to cup her breasts, to knead them until she groaned. Still trapped between her girlfriend and her step-sister, she couldn’t escape the sweet torture. Rebecca knew it, too, didn’t let up until she didn’t think she could take any more.

Caroline’s mouth was doing wonderful things to her, the lazy caresses of her hot, wet tongue delicious. The waves of pleasure washing through her had her hips undulating against her girlfriend’s mouth. She lovingly stroked Caroline’s hair, moaning.

Rebecca kissed her neck where it met her shoulder, then moved to one side, so her body was pressed against Riley’s shoulder. She turned Riley’s face toward hers, then kissed her deeply. It lingered until Riley had to break it as Caroline teased another moan from her. Still pressed against Riley’s flank, Rebecca put her arms around Riley’s neck and looked down at what Caroline was doing to her. Riley saw the flash of excitement in the teenager’s eyes and the smile on her lips.

Riley was making these little wordless sounds of enjoyment, and she couldn’t stop. They only got louder as Caroline eased her fingers into Riley’s ready core. She found the magic button deep inside Riley, teased it with these lazy come-hither motions that made her writhe in pleasure. Her cries became more urgent, filled the room.

Grinning, Rebecca said to Caroline, “Oh my… I think she likes that.”

Caroline rolled her eyes to Rebecca and winked at her. She never stopped the maddening torture on Riley’s body, the one-two punch of her tongue on her clit and the fingers caressing her g-spot almost more than she could bear.

It didn’t take long for her to feel an orgasm gathering steam deep inside. It built and built until she thought it might come out her ears like in a cartoon. Instead, she cried out as climaxed, would have fallen if Rebecca hadn’t been there to hold her up. Her legs felt like jelly as her whole body trembled.

“Alright, Caroline,” Rebecca said, grinning at the girl.

Caroline stood up, and Riley pulled the girl into her arms and kissed her. The kiss was unceremoniously ended when Rebecca scooped her up like a bride on her honeymoon and carried her to the bed. She giggled as the teenager tossed her onto the mattress and she sprawled very unladylike on her back. She watched with interest as the girl crawled onto the bed with her, looked down at her from her hands and knees. Rebecca leaned in and kissed her, then moved, so she was straddling one of Riley’s hips.

Riley moaned as their bodies nested together. Her body was still very sensitive from the orgasm she had just had, and the feel of Rebecca’s body rubbing against hers felt incredible. Then the girl began to move, the rock of her hips grinding her lower abdomen against Riley’s. She took it slow and easy, giving Riley a chance to almost recover but not quite.

Caroline stretched out beside Riley, letting her hands roam over Riley’s supine body. Her touch left Riley’s skin tingling. She kissed Riley, helped distract her from the waves of pleasure crashing through her body.

Rebecca put her hand on Caroline’s hip, lightly caressing her skin. Caroline looked at her, and Riley saw an unspoken consent pass between them. Getting to her knees, Caroline kissed Rebecca. It was a hesitant, uncertain kiss, at first, but then it deepened as both girls relaxed some. When she finally broke it, Caroline gave Rebecca a shy smile, bit her lip. Rebecca grinned at her and put her hand on Caroline’s neck, pulled her back into the kiss.

Watching her girlfriend and step-sister kissing, Riley had to grin, then wondered why it turned her on so much.

Rebecca’s hips began to gyrate faster, forcing moan after moan from Riley. The sensual flex of the teenager’s body was mesmerizing and Riley found herself watching the way she moved. She found it almost as exciting as the sensations the meeting of their bodies was sending through her.

Riley’s cries became more urgent as she felt another orgasm building up inside. Both Rebecca and Caroline heard the changed and looked down at her. With their eyes on her, she climaxed for a second time this evening and the fourth time for the day. Her young body tried to shake itself apart as Rebecca slowed her pace to a crawl. The easy flex of her hips kept the wonderful sensations coursing through Riley.

After a moment, Rebecca finally crawled off Riley. Getting off the bed, she said, “I’ll be back in a second.”

“I’ll keep her entertained while you are gone,” Caroline said, giving Riley a playful smile. Then her lips were pressed against Riley’s, her tongue in Riley’s mouth. It lingered until Riley had to come up for air.

Letting her catch her breath, Caroline kissed her collarbone, and then the slope of one breast. Her tongue traced around Riley’s areola, and then she gently bit the nipple, drawing a groan from Riley. She continued her journey down Riley’s supine body, leaving a trail of kisses on her sweaty skin. She moved between Riley’s legs, spread them wide. Grinning, her mouth found Riley’s bud.

Giving Riley a playful smile, Caroline said, “I can taste Rebecca on you.”

Riley moaned thickly. Her body hadn’t even come close to recovering from her last orgasm and Caroline’s able tongue had her writhing, again.

Rebecca returned with a gift bag in her hand. Sitting on the bed next to Riley, she said, “I’m a little jealous. I didn’t have one of these when I was your age.”

“One of what,” Riley said, her words drawn out in a moan.

“Just a present for the cute couple,” she said, grinning as she reached into the bag.

Caroline stopped what she was doing for a second and both girls watched as Rebecca produced something from the bag. A gift for both of them, Rebecca had said. Riley saw the curious looking thing in her step-sister’s hand, not sure exactly what she was looking at. She’d never seen anything like it before.

“Is that what I think it is,” Caroline asked, her eyes wide.

“It’s a strapon,” Rebecca said, holding it out to the stunned girl, “I figure you should be the one to break it in.”

Caroline took it, shook it out, then held it up for Riley to get a better look at it. She started laughing when she finally understood what her step-sister had given them. It was a black leather panty that was mostly adjustable straps. A black dildo poked out the front, maybe five inches long and inch or so in diameter.

“You bought us a strapon,” Riley asked, laughing.

“I guess technically Helena bought it for you, but I paid her back,” Rebecca said.

“Oh God,” Riley said, her face coloring at the thought of seeing the piano teacher for her next lesson. The woman had already known too much about her sex life as it was. Now, she knew even more.

Caroline was struggling with the harness, didn’t seem to have enough hands to get it secured in place.

“Let me help you with it,” Rebecca said, moving behind Caroline.

She took the strapon from Caroline, held it in place while the girl worked the straps. With it snug in place, Rebecca wrapped her fingers around the shaft of the dildo, pumped her fist up and down it a few times. Caroline’s eyes widened and she giggled. She bit her lip and sighed as Rebecca continued to stroke the dildo.

Putting her chin on Caroline’s shoulder and grinning at Riley, Rebecca said, “As you can see, it can feel nice for both of you. Thrusting puts pressure in a very lovely place. Right, Caroline?”

Caroline nodded, moaning. Riley could tell by the look on her girlfriend’s face, that what Rebecca was doing to her felt good, could see it in her hooded eyes and her slack mouth. Rebecca put an arm around Caroline’s neck, never stopping her steady stroking of the dildo. Caroline’s moans got louder, her face screwing up in pleasure.

Riley watched this curious reach around with a mixture of amusement and excitement. It was kind of weird, watching Caroline get a handjob but kind of sexy at the same time. Rebecca saw her and gave Riley a knowing, playful smile. Riley blushed as she realized her step-sister knew she was getting turned on by what she was doing to Caroline.

“What do you think, Birthday Girl,” Rebecca said, her voice teasing, “are you ready for Caroline to put this thing inside of you?”

Riley’s cheeks were even hotter as she nodded.

Rebecca wasn’t going to let her off that easily, said, “What do you want Caroline to do to you?”

“I want… I want her to fuck me,” Riley said, with a naughty little shiver working up her spine. She looked at Caroline and said, “I want you to fuck me with that strapon.”

“Hear that Caroline,” Rebecca cooed in the girl’s ear, “she wants you inside of her.”

With that, Rebecca released Caroline and the girl moved between Riley’s spread legs. Half sitting up, Riley helped Caroline slip the dildo into her ready vagina. Riley collapsed to her back, moaning thickly as the shaft bit deep into her core. Caroline looked anxiously at her and Riley smiled at her, moved her hips against the toy. It was all the encouragement Caroline needed. She pulled the dildo part way back out, only to push it back in. Riley moaned again, wrapped her legs around Caroline’s hips, her ankles crossing. Caroline found a slow, maddening rhythm that Riley loved, each thrust pushing a moan from her slack mouth.

Rebecca crawled behind Riley, sat down with her legs to either side of Riley’s head. She encouraged Riley to sit up a bit and she moved forward. Riley found herself leaning back into her step-sister’s arms, her breasts mashed against Riley’s back. Rebecca’s hands roamed over Riley’s young body, exploring every inch of her they could reach.

Craning her neck, Riley kissed her, put a hand behind the teenager’s head to hold her to the kiss. Her fingers knotted in Rebecca’s hair as the dildo found the secret spot deep inside of her. She moaned into Rebecca’s kiss, then had to break it as another thrust found the mark. Turning back to Caroline, she saw the girl grinning and knew Caroline had heard the change in her cries and knew what that meant. Another thrust found her g-spot and her body went crazy.

“Oh God, that feels good,” Riley said, her words drawn out in a moan.

Grinning, Caroline let her pace slowly increase, her thrusts coming faster and faster. Riley rolled her hips up, meeting her counter-thrust for thrust. Each time the dildo slipped deep into her slick core, it sent waves of pleasure crashing through her. Each new one seemed to crest higher and crash harder into her, forcing cry after cry from her.

Rebecca whispered in her ear, “She’s pretty good with that thing. It took me a while to get the hang of it. It’s all in the hips.”

Riley had to agree; Caroline was doing wonderful things with the strapon, had her writhing in ecstasy.

“She was already a keeper,” Rebecca whispered in her ear, her hands cupping Riley’s breasts, “but if she can fuck like this…”

Rebecca knew the dirty talk was a weakness of Riley’s and she laughed when Riley shivered.

“What are you two whispering about,” Caroline said, her voice thick.

“About how much she likes your cock inside of her,” Rebecca said and Riley got another naughty shiver up her spine.

Caroline giggled and said, “Wow.”

“You should let her ride that thing for a while,” Rebecca said, winking at her.

Caroline raised her eyebrows questioningly.

Rebecca patted the bed beside her and Caroline eased out of Riley. She stretched out beside the teenager. Rebecca urged Riley to straddle her girlfriend’s hips, helped her ease down onto the dildo. It took a little practice, but Riley found what she liked. Being in control was nice and she quickly found her pace.

She leaned down, kissed Caroline deeply. The girl wrapped her arms around her neck, wouldn’t let her pull back from the kiss. As their tongues twined, Riley didn’t stop moving up and down on the dildo, her body like a pneumatic pump.

“Where do you keep your vibrator,” Rebecca asked, looking around the room.

“It’s in the lamp,” Caroline answered, even though the question was aimed at Riley. It drew a smile from Rebecca and she gave Riley a knowing look. She could only grin and shrug.

Rebecca went to the lamp, picked it up. Seeing the duct tape on the bottom, she pulled it back and the vibrator fell out of the base of the lamp. She sat the lamp down, then picked up the vibrator.

“Nice hiding spot,” she said, nodding appreciatively.

Riley glanced at the teenager as she moved behind her. Rebecca turned the knob at the base of the vibrator and it came buzzing to life. She pressed the toy against the hilt of the dildo and suddenly rubber dong was vibrating deep inside of her. A startled gasp escaped her as the intense sensation seemed to spread all through her body.

Caroline’s face pinch in a rictus of pleasure and Riley realized her girlfriend was feeling the vibrations as well. Riley forced herself to relax, so they might come together. Reaching behind her, she pushed Rebecca’s hand lower, so the vibrator was more squarely on Caroline’s girlhood. Rebecca met her eyes and Riley saw her start to grin, then nod. Rebecca got it.

The vibrator and Riley’s pneumatic body proved too much for Caroline and Riley felt her start to come. Riley let her own orgasm off the leash and they climaxed together. They shook like live wires had been laid across them. Gasping for air, Riley sat astride Caroline, the dildo still buried deep in her spasming girlhood. Rebecca didn’t remove the vibrator from Caroline’s pussy and she twitched as the buzzing found her now very tender bud. Riley moaned every time Caroline’s hips jerked, the dildo moving inside of her. Rebecca finally moved the vibrator and both girls sighed with relief.

Riley threw her leg over and got off of Caroline. Her thighs were like jello as she collapsed onto her back next to her girlfriend. She felt so light that she thought she was in danger of just floating away. So she was glad when Caroline rolled into her and put her arm around her shoulder.

“Ready to go again, Birthday Girl,” Rebecca asked, running her fingernails up and down the insides of Riley’s thighs.

“No,” Riley said, laughing, “It’s someone else’s turn to be the monkey. I need to catch my breath.”

Rebecca grinned at Caroline and said, “I think we broke her.”

Laughing, Caroline said, “I hope not. It’s still early.”

“Here,” Riley said, pulling her birthday hat off her head and putting it on Caroline, “you can be the monkey.”

“Me,” Caroline asked, then glanced nervously at Rebecca, “you do understand what that means right?”

“That you and Rebecca are about to get to know each other a whole lot better,” Riley said, grinning at her, “assuming you are both interested.”

Caroline glanced at Rebecca and the teenager smiled at her, said, “At this point, it is just a formality, anyway. We crossed that particular line a while ago.”

Grinning, Caroline said, “Yeah, I guess we did.”

Rebecca crawled up Caroline’s supine body, gave her a kiss. Caroline slipped her hand into the teenager’s hair, held her there. The kiss deepened and Riley saw passion blossom between them. The caressing of their tongues grew urgent as both girls became excited.

Breaking the kiss, Rebecca grinned at Caroline as her fingers fumbled with the buckles on the strapon harness. She managed to free one of them and slipped the rig off Caroline, tossed it aside. She hooked her fingers in Caroline’s itty bitty thong then stopped.

Giving Caroline a playful smile, she said, “You should put the panty on over the garters for easy access.”

Caroline looked down at herself, then gave Rebecca a sheepish grin, “I guess that makes sense.”

“No worries,” Rebecca said, hooking her fingers in the crotch of the thong and pulling it aside, “I can manage.”

A nervous, excited giggle escaped Caroline as the teenager moved between her spread legs. She bit her knuckle as Rebecca lowered her mouth to her girlhood, her tongue teasing her bud. Her eyes were intent on the teenager.

“Well, this is happening,” Caroline said, her voice a little thick.

Laughing, Riley kissed her and took her hand. Caroline looked at her, her face screwing up as Rebecca’s able mouth teased her bud. Caroline’s fingers tightened on her hand. Riley could feel the pleasure coursing through her girlfriend.

Riley kissed Caroline’s chin, and then her neck, her collarbone. She tasted the salty sweat on her skin with her tongue. She pulled first one shoulder strap of the bustier, then the other down, revealing Caroline’s small, perky breasts. Caroline groaned as Riley teased her straining nipple with her tongue. Her back arched as Riley used her teeth to nibble that stiff nub gently. She didn’t let up until Caroline couldn’t take anymore, then moved on to the other one. Caroline’s hand knotted in her hair as she tortured her tender nipple.

Out of the corner of her eye, she saw her vibrator sitting on the comforter, grinned. She picked it up, turned the knob to bring it to life. She pressed it to the slight swell of Caroline’s girlhood just above where Rebecca was using her mouth to torture Caroline’s bud. No sooner did the vibrations find her young body did Caroline’s cries go sharper. Her hips began to jerk and her stomach muscles contract, her body moving with a mind of its own. Rebecca had to use her free hand to trap one of her thighs to keep her mouth to Caroline’s writhing body.

Riley moved further down the bed. As she held the vibrator to Caroline’s lower abdomen, she let her hand slip down Rebecca’s back and onto her buttocks. The teenager spread her legs more, giving Riley easier access. Her hand slipped between Rebecca’s thighs to tease her clit. Rebecca moaned against Caroline’s girlhood, her hips undulating against Riley’s hand. Riley kissed Rebecca’s shoulder, then left a trail of moist kisses down her spine. The teenager shivered.

The vibrator and Rebecca’s tongue proved too much for Caroline and the girl cried out as she came, hard. Riley was distracted by Rebecca’s lovely body, didn’t pull the vibrator away fast enough. Caroline cried out, again as a second orgasm had its way with her. Caroline pushed the toy away in a hurry, gasping. Riley looked at her, saw her trembling, her eyes wide. She brushed her hair from her face, laughing.

“Holy shit,” she said, breathing heavy.

Rebecca crawled up and gave her a kiss, then stretched out beside her. Riley moved up and kissed her, too. She grinned down at the girl, said, “That looked intense.”

“I came twice, like bam, bam,” Caroline said, shaking her head, “I swear, I could feel the vibrator in my toes.”

“I bet you could,” Rebecca said, laughing.

“And you,” Caroline said, smiling at the girl. She rolled onto her side and gave Rebecca a heated, lingering kiss. When she pulled back, she grinned at the teenager, then moved down her body and in between her legs. Rebecca propped up on her elbows, watching with interest as the girl brushed her hair out of face and lowered her mouth to the teenager’s clit. Rebecca looked up at Riley, raised her eyebrows. Riley nodded, giving her permission.

Caroline was on her knees, her ass up in the air. Grinning, Riley reached for the strapon, fiddled with it until she had it on. Moving behind her girlfriend, she eased the dildo into her ready sex. Gasping, Caroline looked at her over her shoulder, her eyes wide. Then she started grinning, pushed back against the toy. Riley grabbed her hips, began to thrust slowly in and out. Caroline moaned each time the dildo bit deep.

Caroline returned her attention to Rebecca, her mouth teasing the teenager’s clit. The pressure of her tongue had Rebecca sighing, her hips undulating against Caroline’s mouth. Rebecca found the vibrator, turned it on and pressed it against the swell of her sex. A thick moan escaped her and Caroline gave her a knowing smile. Rebecca managed a smile before her face screwed up in pleasure.

Riley gradually let her pace increase, each thrust coming faster the one before it. Caroline started having difficulty keeping her mouth to Rebecca’s clit, couldn’t stop moaning. Finally giving up, she wet two fingers and eased them into the teenager’s slick core. Caroline glanced over her shoulder at Riley and she saw how much the girl was enjoying what Riley was doing to her.

Letting one hand slip from Caroline’s hip and into the junction of her thighs, Riley teased Caroline’s bud without slowing down the roll of her hips. Caroline’s cries became sharper, the dueling sensations driving her body wild.

Hearing Rebecca’s cries mingling with Caroline’s, Riley looked around her girlfriend and saw that Caroline and the vibrator had Rebecca a mess. Her eyes were closed and her mouth slack, moan after moan dripping from her lips. Her body was writhing against Caroline’s hand. Suddenly, Rebecca’s eyes sprung open. Riley heard her cries become sharper and she knew the girl was about to come.

With one more cry, Rebecca climaxed, her whole body arching off the bed. She collapsed back to the bed like a balloon whose knot had been released and she pulled the vibrator away. Caroline didn’t stop teasing her g-spot and Rebecca twitched like she was being shocked. Only a few seconds after the first, Rebecca stiffened with another orgasm, this one cutting her cry off midway. This time, Caroline eased her fingers out of the teenager, gently rubbed Rebecca’s bud to keep the wonderful sensations rolling through the girl. Rebecca stretched like a cat in a sunny spot and Riley thought she was about to start purring.

Riley put her hands on Caroline’s shoulders, urged her to her knees. She wrapped her arms around the girl, held her close as she continued to thrust the dildo in and out. Kissing Caroline’s neck where it met her shoulder, Riley let her hands slip up Caroline’s sides to cup her small breasts. Caroline moaned and sighed, her hands out behind her to grab Riley’s buttocks.

Sitting up, Rebecca used the vibrator to torture Caroline’s bud, pressing it against that tender spot. Her free hand roamed over Caroline’s stomach and thighs, explored the girl’s lithe and lean body. Seeing the smile tugging at the corners of her stepsister’s mouth, Riley knew the teenager found Caroline as tempting as she did.

Too many wonderful things were happening to Caroline’s young body and Riley felt her start to come. One, two, three more thrusts and she felt the girl stiffen in her arms. She slowed to a stop, held the girl as the orgasm had its way with her. Caroline was trembling all over from the intensity of her climax.

It went unspoken but all three girls were sated. They untangled themselves, sat around looking at each other. Slow grins spread on all of their faces.

“That was…” Rebecca said, then stopped when she saw Riley and Caroline nodding. She didn’t need to finish the thought. Giving them a playful smile, she said, “You know, my birthday is in February.”

—————————————

The hiss of the shower was soothing and the warm water felt wonderful but not as wonderful as Caroline’s body pressed against her back or her arms around Riley. Turning into the girl, Riley kissed her deeply.

“Thank you for this,” Riley said, smiling at her.

“I can’t believe we actually went through with it,” Caroline said.

“Any regrets,” Riley asked, meeting her eyes.

“No,” her girlfriend said, smiling, “You?”

“No.”

“Good,” Caroline said, putting her head on Riley’s shoulder. She sighed contentedly as Riley wrapped her arms around her, held her tight. They stayed that way awhile, just enjoying the closeness.
