Home Alone, Part Six

“Just give it a chance,” her stepmother said, glancing at her in the passenger seat.

Riley nodded, tried to muster up some excitement about her first day of piano lessons. The idea of learning to play music was kind of cool and Rebecca seemed to enjoy her lessons. Maybe it wouldn’t be too bad.

Still, she got the feeling her stepmother had signed her up for these lessons just to get her out of the house for a while.

As they drove in an awkward silence, Riley wonder what Caroline was doing. Thinking about her oldest friend made her smile, then thinking about the curious turn their friendship had taken, she smiled even brighter. Most of the awkwardness had worn off of fooling around with Caroline and, now, it was just fun. It surprised her a little how quickly and how easily she took to sleeping with her.

They weren’t a couple or anything, just liked to have sex on occasion. That night, after their first fumbling, hot attempt at being together, they had had a long discussion about what it meant to their friendship. They had decided it didn’t really change much. The thought of trying to date had made them fall out in stitches.

So, they were friends… with benefits.

Riley was jostled from her thoughts when they made a right turn into a driveway, came to a stop. She noticed the sign on the door reading ‘On That Note’ and realized they were there. Unfastening her seatbelt, she glanced at her stepmother, then opened the door.

“I’ll be back to pick up at eight,” she said, smiling, “Have fun.”

“Okay,” Riley said, getting out of the car. She watched her stepmother drive away, then went to the door. Spotting a buzzer on the frame, she pressed it. A few seconds passed, then a smiling woman answered the door.

Riley gasped in surprise, recognizing the woman even before she introduced herself. Her mind flashed back to the second time she snuck into her sister’s room, to the video of Rebecca and a thirty-something year old woman kissing. She could see the woman’s face clearly and she was looking at her now.

The piano teacher was Hgreg@yahoo, Rebecca’s lover.

“You must be Riley,” the woman said, offering her hand, “My name is Helena Greg. Come in and we’ll get started.”

Helena must not have noticed her recognition, the stunned look on her face. Still, it seemed impolite to leave the hand hanging, so she shook it, found herself being led by it to the den where a large, imposing piano took up one corner.

“Have a seat at the piano,” Helena said, releasing her hand.

————————————————————————-

“How was piano practice?”

Riley started, looked around at her step-sister standing in the open doorway to her room. Thinking about the teacher, the woman Riley knew to be Rebecca’s lover, she blushed. Guilt snuck up on her and she felt like an ass for invading her privacy. Definitely wished she didn’t know about the illicit affair between Rebecca and Helena Greg.

The whole practice had been one long, awkward moment.

She hadn’t known what to expect from the piano teacher but was a little surprised when she liked the woman. She was funny, patient, a really good teacher. Riley felt she shouldn’t like her, that she should be on her guard, but the woman had a way about her. She had made Riley relax at times, to forget she had molested her step-sister. Then she’d remember and her concentration would go out the window.

She could see why Rebecca could fall for her.

Her step-sister saw her blush, her face pinching in anger, as she said, “Let me talk to you for a minute.”

Blinking in surprise, Riley realized she was being admitted into Rebecca’s room. Frowning, she followed her step-sister into room, the frown deepening when she closed the door. This was very unfamiliar territory, not just being in the room, but being acknowledged by girl in general. Something important was happening. What, she had no idea.

“Mom came to me, asked about signing you up for lessons,” Rebecca said, sitting on her bed. She sighed, shook her head, “I tried to talk her out of it without seeming like I was trying to talk her out of it. Told her you were tone deaf, heard you singing in the shower. It didn’t work. She told me to stop being mean and signed you up, anyway.”

“Okay,” Riley said, still frowning.

“I don’t know,” she said, running a hand through her hair, “I guess, I should have told her the truth then. Maybe, it would have spared you from the woman.”

“The woman?”

“Ms. Greg. Helena,” Rebecca said.

“Spare me from her?”

Frowning, Rebecca asked, “She didn’t touch you?”

Blinking in surprise, Riley said, “Touch me? No.”

“I… When you blushed when I asked you how piano practice was… I just assumed…,” Rebecca said, flustered.

Riley realized her step-sister was actually concerned about her, had thought the piano teacher had tried something. She was touched by the gesture and more than a little surprised by it. Then she felt like a real ass because she had blushed for a whole different reason. It was guilt that colored her cheeks.

“Rebecca,” Riley said, sighing, “I’m sorry. I know about you and Ms. Greg. I snuck into your room, found a video of you two on your computer. I know it was a shitty thing to do and I feel horrible about it.”

“And that is why you blushed when I asked about piano practice,” Rebecca said, nodding.

“Yeah. I’m sorry for invading your privacy.”

Sighing, she nodded, “It’s okay. I already knew you’d been in my room.”

Blinking in surprise–something she had done a lot since coming into this room–Riley said, “You did?”

“I always leave my webcam on recording when I leave the house. I liked to know if Mom has been in my room.”

“Oh,” Riley said, then just what that meant sank in. Her cheeks turned scarlet and she looked away in embarrassment. The scene with the vibrator played in her head and her face grew even hotter.

Seeing it, Rebecca laughed, “Yeah. You put on quite a show.”

“Oh, God,” Riley said, wanting to flee the room.

“You snuck in here a few more times to borrow my vibrator, then you just stopped,” Rebecca said, laughing, “Why is that?”

Riley looked at her, then said, “I have my own.”

“You do,” Rebecca said, her eyes widening as she laughed, “Really?”

“Yeah.”

“This has to be a good story,” her step-sister said, leaning forward, “Grab a chair. I have to hear how a twelve year old ends up with a vibrator.”

Riley really didn’t want to tell the story but she felt she owed Rebecca something for invading her personal space. That and this was the longest conversation they’d ever had, as far as Riley could remember. Maybe it was the start of a tenuous relationship between them.

Shaking her head, she pulled the office chair away from the desk, sat down. With a deep breath, she said, “I was at the mall, in Spencers, looking for a gift for a friend. You know that one section of the store, where they have adult novelties?”

Rebecca nodded, then laughed when she sensed where the story was headed.

“Anyway, there was a display for ‘personal massagers’. Boxes and boxes of vibrators. So close but no clerk would ever sell one to me, a twelve year old girl.”

Laughing, Rebecca said, “You have the itch bad, huh?”

“Bad enough to steal one of them,” Riley admitted, blushing.

“You stole a sex toy from the mall,” Rebecca said, shaking her head in amusement, “That is priceless.”

“So, now you know,” Riley said, wondering if it were possible to get any more blood in her face. Probably not.

“And I’m the one the parents talk about as the problem child,” Rebecca said, shaking her head in mock dismay.

Riley had to laugh at her own expense.

“So it wasn’t your conscience getting the better of you,” Rebecca said, grinning, “you just found another plaything.”

“I really am sorry about sneaking into your room.”

“I’m just messing with you,” she said, then, “seriously, though; stay out of my room.”

“No problem.”

“Anyway, I guess warning you about Helena is a waste of time, now.”

“What is the story with you two?”

“Story?”

“How’d the video come about?”

“Oh,” Rebecca said, laughing, “You really want to know about that?”

“You can tell me it is none of my business, if you want.”

Rebecca looked at her a long moment, then shrugged, “I started taking piano lessons when I was about your age. Helena was married then, her husband a real piece of work. Cheated on her all the time, might even have hit her. I never saw any marks but I just got the feeling…

“About the time he finally left her, my parents were splitting up. We really bonded then, kinda leaned on each other for support. We became friends. The sex part came later.”

“So, she wasn’t, well…” Riley said, then trailed off when she didn’t know how to put the thought into words.

Luckily, Rebecca seemed to understand what she was asking, “Was she a pedophile?”

“What is a pedophile?”

“An adult who messes around with kids?”

“Oh,” Riley said, her eyes wide.

“I guess, technically, she was,” Rebecca said, then shook her head, “I was the one who instigated the relationship. She never would have touched me if I hadn’t seduced her.”

“You seduced her,” Riley asked, blinking in surprise. She really needed to stop doing that before it becomes permanent. She’d just walk around blinking in surprise for no good reason.

“I figured out pretty young I wasn’t like most girls. I couldn’t get interested in boy talks,” Rebecca said, shrugging, “when I started noticing I was attracted to girls, it made more sense. I was a lesbian.

“I never told anyone about it,” she said, looking at Riley, “in fact, you are the first person other than Helena I’ve told.”

“Oh,” Riley said, thinking about Caroline. Was this a beginning of a trend, people opening up to her about their sexual orientation, she wondered.

“Anyway,” Rebecca said, going on, “I had all of these pent up feelings, urges I couldn’t find an outlet for. I was scared to act on them. I knew the kids at school could be vicious when you were a little different, didn’t want to paint a target on my back.

“One day, Helena was wearing this summer dress at piano practice and I caught myself admiring her legs. That was the beginning, my realizing she was appealing. Her husband had broken more than just her heart when he left; he had broken her spirit. She didn’t date even though she was pretty enough to turn many a guy’s head.

“She turned her ankle on a throw rug at practice. I got her a bag of ice and rubbed her swelling ankle for a minute. A tension came between us. I was a closeted lesbian and she was a lonely, broken woman. She didn’t stop me when I let my hand slip under her skirt…” Rebecca said, then blushed and laughed when she remembered she was talking to a twelve year old, “Anyway, that was the first time.”

“Good,” Riley said, relieved she had read the videos right. She felt better about not telling Rebecca’s mother about it.

“Good,” Rebecca repeated, raising her eyebrows.

“I was agonizing over whether I should tell someone about the videos,” Riley said, grinning sheepishly, “You seemed so happy in the videos, I decided not to. Did I make the right decision?”

“Helena is harmless,” Rebecca said, then smiled, “The videos were my idea, something to spice up the relationship.”

“Yet, you were concerned about Helena trying something with me,” she said, reminding the teenager about her concern.

She sighed and said, “I really didn’t think she’d do anything. It is just you are a pretty girl and…”

“So it was jealousy not concern for my well being that motivated you to tell your mom not to sign me up for lessons,” Riley said, smiling.

“It was a little of both,” Rebecca said, then grinned sheepishly, “Although it was more jealousy than concern.”

“You have feelings for her,” Riley said.

It wasn’t a question but Rebecca answered her anyway, “I love her.”

“I know,” Riley said, grinning, “I could see it in your eyes in the videos.”

Sighing, she said, “But, I’m not in love with her. Do you know what I mean?”

“Not really,” Riley said.

“She was my first, so she’ll always have a place in my heart but… I don’t know. I always imagined I’d find someone who’d take my breath away. Being with Helena is fun, exciting but I’ve never felt that with her.”

“Okay,” Riley said, thinking she understood.

“Maybe I’m overthinking it, expecting love to be like a romance novel,” she said, shaking her head, “I really do like being with her. She is sweet, funny. Great in bed.”

Riley laughed at that last line and Rebecca winked at her.

“My only real complaint is I don’t get to be with her very often. Just the one time a week,” Rebecca said, sighing.

“Yeah, I get that,” Riley said, nodding. She missed fooling around with Caroline when they were apart.

Rebecca gave her an odd look, her eyes widening in surprise, “What’s with that statement?”

“What do you mean?”

“It didn’t sound like a one off, sarcastic statement,” Rebecca said, looking expectantly at her, “There was a little feeling behind it.”

Blushing, Riley realized she might have put her foot in her mouth, she said, “No, I just meant-“

“Oh, my God,” Rebecca said, laughing, “Who is it?”

“Who is it,” Riley parroted.

“You are sleeping with someone,” Rebecca said, certainty in her voice. She favored Riley with a knowing smile.

“I’m-” she started to deny it but her step-sister didn’t let her.

“Come on, now,” she said, laughing.

Riley looked at her a long moment, then sighed, “Fine. You are right.”

“Anybody I know,” she asked, then laughed when Riley’s reaction to the question gave her away, “Who is it?”

“Oh, God. I can’t believe I’m telling you this,” Riley said, shaking her head and laughing, “It is Caroline.”

“Your friend,” Rebecca said, her eyes widening, “then you are a…”

“A lesbian,” Riley asked.

“Yeah.”

“No,” Riley said, then, “Well, maybe. I guess a little.”

“Huh,” her step-sister said, looking at her, “I didn’t see that one coming. I thought you had a boyfriend or something. Didn’t know it was a girlfriend.”

“She isn’t my girlfriend. Just a friend,” Riley said.

“That you’ve slept with?”

“Yes,” Riley said, laughing at the look Rebecca gave her.

“So what, are you just fuck buddies,” Rebecca said, grinning, “Friends with benefits?”

“I’m going to regret telling you,” she said and it wasn’t a question.

“Maybe,” Rebecca said, then grinned mischieviously, “So, what have you two done?”

“Done?”

“I’m assuming you’ve kissed.”

“Yeah,” Riley said.

“Anything else,” Rebecca asked, laughing when Riley’s face colored again, “Oh, my God! You have!”

“I’m going to go,” Riley said, started to get up.

“Come on,” Rebecca said, grabbing her hand, “Don’t be like that. I don’t get to talk about this stuff with anyone.”

“This stuff?”

“Lesbian stuff,” she said, then rolled her eyes, “All my friends are straight and I have to pretend to be interested in their boy stories. I just want to have a conversation with another lesbian. Even one as young as you.”

Riley looked at her a long moment, saw the genuine desire in her eyes. She really couldn’t say why she did, but she sat back down.

“So,” Rebecca said, leaning forward, “how did it happen?”

Sighing, Riley said, “Caroline opened up to me about having urges lately. I didn’t know what to say. It was an awkward wedge between us and I panicked. I didn’t want to lose my best friend over it. I just kissed her.”

“You kissed her,” Rebecca asked, her eyes widening.

Laughing, Riley said, “Yeah. I kissed her, said I refused to let this ruin our friendship. Things kind of snowballed from there.”

“Snowballed,” Rebecca asked.

Riley blushed, “Do you really want to hear this?”

“Oh, wow,” her step-sister said, laughing, “Things got serious, huh?”

“Pretty serious,” Riley admitted.

“What are we talking,” she said, grinning, “Third base?”

“What is third base for lesbians?”

“I guess eating or fingering pussy,” her step-sister said, laughing at the shocked look on Riley’s face.

“What’s the other bases,” Riley asked, not sure she was ready to admit to Rebecca that she and Caroline had made it to third base.

“First is kissing,” Rebecca said, tapping a finger on her chin, “Second is touching her breasts. We already covered third base. I’m guessing home would be tribbing or using a vibrator.”

Riley realized she and Caroline had made it a lot further than third, it turned out. Rebecca was looking at her and must have seen that realization cross her face. She blushed as a knowing smile spread on her step-sister’s face.

“What, did you use your vibrator on her,” Rebecca asked, laughing.

Riley didn’t answer, which was still answer enough.

“So, what else have you two tried,” Rebecca asked.

Her face hot, Riley said, “We might have tribbed a little. Used our hands.”

“Didn’t go down on each other,” Rebecca asked, laughing.

“No.”

“You should try it,” her step-sister said, winking, “feels incredible.”

Riley squirmed, uncomfortably. She wasn’t sure she was ready to have this kind of conversation, yet. Just some of the terminology was making her blush, her step-sister not making any effort to clean up the vulgarity for Riley’s sake, anymore.

“It was a little weird the first time I let Helena eat me out,” Rebecca said, then shivered, “but it felt so good, the weird wore off pretty quick.”

“Did you, you know, to her?”

She laughed and said, “You can say it, you know. Try it on for size one time.”

“Did you eat her out,” Riley said, her face hot.

“You mean, did I lick her pussy clean,” Rebecca said, laughing as Riley’s eyes got big as saucers, “then yeah, I did. That was an experience, let me tell you. Still, hearing her go crazy from my tongue on her clit… Something satisfying about making another person squeal like that.”

Maybe she was becoming numb to the explicit language her step-sister used, but it didn’t make her as uncomfortable as before. That should probably make her a lot more nervous than it did. The very inappropriate way she described her relationship with Helena was kind of exciting in a way. Dirty.

Rebecca was looking at her funny, then said, “You look a little flushed.”

“I’m just embarrassed,” Riley said, which wasn’t completely true.

“Maybe,” Rebecca said, grinning, “but that isn’t all. Your breathing got all funny when I started talking about eating Helena out.”

“I should go,” Riley said, looking at the door.

“It is okay to be turned on,” Rebecca said, putting a hand on her thigh, just above the knee, “Talking dirty does it for me, too.”

“I’m not turned on,” Riley said, pushing the hand away.

“Tell that to your nipples,” Rebecca said, laughing.

Riley looked down at herself, saw her nipples straining against the thin material of her shirt. Her face grew hot with embarrassment and she crossed her arms over her breasts.

Rebecca grabbed the office chair, pulled Riley right in front of her. Riley found herself very close to her step-sister, felt a tension between them. The way she was smiling at Riley wasn’t helping, one corner turned up in a playful smirk.

“I wasn’t kidding when I said you were a pretty girl,” Rebecca said, meeting Riley’s gaze.

Riley saw the interest in her eyes, wanted to look away but she was transfixed by the desire behind them. Her heart knocked around in her chest as she realized her step-sister was attracted to her.

This was even more awkward than finding out Caroline thought she was attractive. First her best friend, now her step-sister.

The hand was back on her thigh, higher this time. Rebecca’s thumb was gently rubbing back and forth, making her skin tingle.

“I’ve noticed you walking around in these tiny shorts you love to wear,” Rebecca said, still caressing her thigh, “You’ve got these long legs for a girl your age, always on display.”

Riley swallowed hard as the hand inched higher. It stopped just below the hem of the very shorts Rebecca was commenting on.

“Sometimes I wonder what it would be like to spread those legs…” Rebecca said, gently pushing one leg open. Her other hand fell on Riley’s other leg, pushing it open. Her eyes dropped to the junction of the girl’s thighs, her gaze hot on Riley’s sex through the thin cotton of her shorts. A playful smile tugged at the corners of her mouth as she said, “and pull the shorts aside to reveal your pretty little pussy…”

She heard the words, should have know it was coming but she still gasped when Rebecca did just that, her knuckles brushing against her girlhood as she pulled the shorts and panties aside. Rebecca’s boldness had her rooted in her spot and she couldn’t work up the saliva to tell her to stop. Her heartbeat was thundering in her ears and she could barely breath.

“And it is a pretty pussy,” Rebecca said, her eyes hot on Riley’s skin, “A peach like that, I could eat all night long.”

Gasping, Riley tried to say something, but stammered a bunch of nonsense instead.

“Got you all flustered, huh,” Rebecca said, then leaned forward and kissed Riley, her tongue slipping into her mouth when she opened it to gasp. Her tongue teased Riley’s into a kiss and she responded without meaning to. Rebecca drew her into a deeper kiss, their tongues tangling in a frenzy.

Pulling back, Rebecca smiled at her, said, “You are a nice kisser. Makes me wonder what else you can do with that tongue.”

A little dizzy from the kiss and more turned on than she wanted to admit by the filth spilling out of her step-sister’s mouth, Riley flushed with excitement. Rebecca had her in a state, couldn’t think clearly about what was happening.

Rebecca let her shorts and panties fall back into place and Riley was more than a little disappointed. Then her step-sister’s fingers started massaging her through the shorts, mashing her labia in lazy circles.

“Rebecca, we shouldn’t-“

“Why not? You are the one who said you weren’t getting enough pussy from Caroline. I could use getting laid myself,” Rebecca said, adding pressure to her fingertips.

Riley moaned, her hips starting to gyrate on their own. Heat blossomed between her thighs and she really didn’t want Rebecca to stop.

“It sounds like you really don’t want me to stop, anyway,” Rebecca said, grinning as another moan spilled from the twelve year old’s slack mouth. She stopped rubbing Riley’s crotch, removed her hand. Smiling, she said, “If you really want to stop, then go ahead and leave. Or, you can stay and we can have some fun.”

Riley blinked at her, then glanced at the door. She knew she should go, that this was a bad idea. This was her step-sister, a person she had to live with for the for-seeable future. It could get really weird, if they became lovers. Still, she didn’t want to go.

Rebecca laughed and patted the bed beside her, “If you haven’t ran away, yet, you aren’t going to. Come here.”

Getting up, she sat beside Rebecca on the bed. Their lips met, then tongues danced. Again, Rebecca teased her into a deeper kiss than she intended. She felt herself responding, becoming aroused.

The teenager grinned at her when she broke the kiss, then sank to her knees on the floor in front of Riley. She hooked her fingers in the bottom of the T-shirt Riley wore pulled it up. Without thinking, Riley raised her arms and the shirt was removed. She put her arm across her bosom, but Rebecca pulled it away, smiled at her small, upswept breasts. Her hands were warm and soft when they cupped them, let her nipples drag deliciously acrossed her palms. She groaned and arched her back, pushing her breasts into Rebecca’s hands.

The hands slipped down her stomach and into the waistband of her shorts. Riley took a deep breath, then lifted her butt off the bed. It was all the invitation Rebecca needed and she pulled the shorts and panties down and off. She tossed them aside, then let her eyes roam up a now very naked Riley. By the time, she met Riley’s eyes, she was smiling a sexy little smile.

“You have a nice body,” she said, putting a hand behind Riley’s head to pull her down into a kiss, “Still a little girl’s body, just beginning to change. It is kind of sexy.”

Riley blushed, didn’t say anything. She wanted to cover herself but didn’t. The time for modesty had passed.

“Lay back,” Rebecca said, caressing her thighs. Riley did as she was told, looking up at the ceiling. She gasped when Rebecca’s wet lips touched her girlhood. Propping up on her elbows, she watched as the teenager let her tongue flick back and forth across her tender bud. She couldn’t bite back the nervous giggle that escaped her as she realized what was happening. Rebecca was eating her pussy.

The sixteen year old rolled her eyes up at her and grinned, still torturing her clit with her tongue. It did feel incredible but was almost too weird to watch. She flopped on her back, closed her eyes. It wasn’t enough. She put her hands to her face, couldn’t stop giggling.

“This is so weird,” she said, shaking her head. Still, Rebecca’s tongue was sending waves of pleasure crashing through her young body. Her body was writhing with a mind of its own. Weird or not, it liked what was happening to it.

Her step-sister moved lower, the tip of her tongue teasing circles around the opening of her vagina. Then she suddenly stopped. Blinking in surprise, Riley propped up on her elbows and looked at her. Rebecca had her labia spread, was looking wide eyed at her. She glanced up at Riley, frowning.

“You aren’t a virgin,” she asked.

“Oh, that,” Riley said, laughing, “A fence climbing mishap.”

Rebecca flinched in sympathy, then grinned, “Then it is your lucky day.”

She wet a finger in her mouth, then eased it into Riley. The saliva wasn’t necessary; she was so excited her juices were dripping from her wet sex. The finger slipped deep inside, found the sweet spot. She slipped the finger in and out, each thrust finding that magic button that drove Riley’s body wild every time she pressed it.

Grinning, the teenager returned her mouth to Riley’s clit, her tongue continuing its assault. The two sensations–the finger slipping in and out of her and the hot tongue caressing her tender bud–melded into one intense pleasure, more intense than either one by itself. Rebecca knew what she was doing, drove her body crazy. She was a moaning, writhing mess.

“You like what I’m doing,” Rebecca asked, pausing to grin at her.

“Yeah,” Riley moaned, thickly.

“Tell me what you like,” Rebecca said.

“I like when you eat my pussy,” Riley said, a little embarrassed by using such language. Then again, she was more than a little turned on by it.

“Say it again,” Rebecca said.

“I like when you eat my pussy,” the twelve year old said, giggling.

“Keep saying it,” Rebecca said, grinning, “keep saying ‘eat my pussy’.”

In a breath moan, Riley kept repeating those three words. Rebecca seemed happy to oblige, her tongue torturing Riley’s clit. Repeating the vulgarity like a mantra was dirty and exciting and her body was alive with pleasure.

Her hips were gyrating so hard, Rebecca was having trouble keeping her mouth to Riley’s body and was squeezing her thigh almost hard enough to hurt in an attempt to keep her still. It did no good. Riley’s body was out of control, she was so excited.

“That feels so good,” she breathed, her head tossing listlessly. A gasp slipped from her when she felt herself beginning to come. Like a boiler ready to blow, an orgasm gathered steam deep inside of her, built pressure upon pressure until she must surely explode. Then her body clenched up, her back arching off the bed and shoving her trembling pussy into her step-sister’s face. Shaking like a leaf, she collapsed back to the bed.

Rebecca wasn’t finished with her, kept thrusting her finger deep into her spasming sex. Her eyes wide, she had to clamp a hand to her mouth to keep quiet as a second climax rose out of the ashes of the first. It was even more intense than the first, nearly shook her apart. She thought it was over but Rebecca kept thrusting, her finger finding her magic spot every time. A third orgasm grabbed ahold of her and it was almost painful it felt so good. Even through her hand, her cries of ecstasy were getting loud enough to carry outside of the room. Still, Rebecca didn’t stop, pushed her toward a fourth orgasm. It was too much and she had to push Rebecca’s hand away from her very sensitive sex.

She was a panting, trembling mess, dazed from the back to back to back to back orgasms. A faint sheen of sweat covered her young body and her chest heaved as she tried to catch her breath. An involuntary surprised laugh escaped her and she looked wide eyed at her step-sister. The teenager was grinning at her.

“Wow,” she said.

“I don’t remember being able to come like that when I was twelve,” Rebecca said, moving up to kiss her, “I’m jealous.”

“That was intense,” Riley said, holding up her hand so Rebecca could see it shaking.

“Well, it is my turn now,” Rebecca said, getting to her feet. She unbuttoned her shorts, shucked them along with her panties down her long legs and off. Her t-shirt and bra joined them on the floor and she climbed naked onto the bed.

Riley looked at her, drank her in. Rebecca had the body of a goddess; long, shapely legs; flaring hips and a flat, sexy belly; large, high breasts that jiggled when she moved; a pert backside. She looked so soft and inviting stretched out on her side.

Riley found her more than a little appealing, which kind of surprised her. While she had fooled around with Caroline and had liked how her friend looked naked, she hadn’t been anywhere as attracted to her as she was to the naked teenager before her. Something about her beautiful body had Riley’s pulse racing.

She really didn’t consider herself a lesbian, but she might have to rethink that assessment. There was no denying she found Rebecca very sexy.

Rebecca pulled her down beside her, kissed her deeply. It was a lingering, passionate kiss, that left both of them breathless. The space between them melted away and their bodies molded together.

Her hands roaming over the teenager’s soft skin, Riley found Rebecca’s body fascinating, couldn’t stop exploring every swell and dip of her. Rebecca moaned and sighed, enjoyed the caresses, a hint of a smile on her face.

Rolling onto her back and spreading her thighs, she invited Riley to explore further. Riley looked at the dewy thatch of pubic hair, the folds of her sex blushing with excitement. An exhilarating shiver worked through her when she realized what she needed to do. It was only fair, since Rebecca had done it for her.

She had to go down on her step-sister.

Another shiver of excitement worked through her naked body. The thought of putting her mouth down there was both weird and very thrilling. A nervous giggle escaped her as she moved between her spread thighs. Hesitantly, she reached out and touched her sex, massaged the clit with her fingertips. She had to bite back another giggle when Rebecca sighed and wriggled her hips against her hand.

Summoning her courage, she lowered her face Rebecca’s sex, kissed her down there. Her tongue teased the hood of her clit, made her moan. Another nervous giggle welled up inside of her as she realized she was doing it. She was eating Rebecca’s pussy. That thought made it harder to keep the almost manic laugh in check.

The salty taste of her skin, the faint musky scent of her sex, the soft sighs she was making… So many wonderful sensations swirling around her that Riley had to smile. Rebecca’s hips began to undulate against her mouth as her tongue flicked back and forth across her clit. She must be doing okay, those soft sighs becoming moans as the teenager’s arousal grew.

Rebecca’s hand fell on the back of her head, holding her face to her muff. Her fingers knotted in Riley’s hair as her body writhed. Riley took it as a compliment.

“That feels good,” Rebecca said, sighing, “Are you sure you’ve never done this before?”

Riley grinned at her, shook her head.

“A natural, then,” Rebecca sighed.

The rolling of her hips made it hard to keep her focus on Rebecca’s bud. Her cheeks were wet from the teenager’s thrashing and her jaw was starting to hurt. Taking a page from Rebecca’s playbook, she wetted her finger and eased into the hot, slick core of her sex. It sucked at her greedily, pulled her in deeper. She used her finger to give her mouth a break.

Rebecca didn’t seem to mind, her cries of pleasure growing sharper. She was biting her lip to stifle them but it wasn’t working as well as before.

Smiling, Riley thought about Caroline, how her own cries had escalated until Riley had to give her a pillow to put over her face to muffle them. Thinking about the girl, she wondered what she’d think about what Riley was doing, sleeping with her step-sister. Smiling, she knew she’d catch hell from her friend when she told her about this later.

“Oh God,” Rebecca said, her body heaving off the bed.

Thinking about Caroline, she had been distracted and hadn’t realized the teenager was coming. She felt her body tremble around her finger, which was still buried deep inside of her.

“It is okay,” Riley said, smiling at her.
