Wicked Stepsister

"I thought you were showing off for me, you know. Lying out in the sun like that, just waiting for me to show up. You had to know I was coming back. And when you went in the pool with my sis? I saw you looking at me. Were you pretending it was me in the water with you?" She tickled the sensitive part inside his thigh and he groaned again. "Cause I was thinkin' it."

Jesus mother fucking Christ… "Really…?" he grunted. Oh fuck, did I actually say that!?

Her head instantly shot up and turned to meet his stare. "Tyler! Was that interest I actually heard?" She crawled back up onto her knees and leaned over him, her hands pressed against his chest for balance. "Do you like that I was thinking about you?"

His head was swimming. "Uhh…" How do I get out of this…

"Too late!" she grinned. "You admitted it." Her body was instantly straddling his again, and she towered over him triumphantly. "But Tyler… I have a little admission to make…" she bent her head down and roamed her eyes around, as if making sure they were alone, "…I already knew the answer."

His face flushed hot again and he shut his eyes. God. Damn. It.

"The real question is… Who do you like better? Me or my baby sis?" Her hands were running through his hair playfully, and he couldn't help but feel mocked. Yet his hardness wasn't going anywhere. "I mean, I'm not blind. I know she's cute." The way she said it was so derisive. "But she's just so boring. Don't you want a little more spice?" Her ass pushed backwards and began to rub against his erection through the board shorts. He couldn't swallow the huge sigh of desire in his throat.

"Oh I'm sorry… I know boys can be kind of simple sometimes. I'll try to narrow it down. Let me ask a more direct question…" She leaned up straight and stretched her arms behind her, which pushed out her chest. "Are you an ass man or a tits man?"

He knew there was no safe answer out of this… Her butt wriggled against his lap and teased his erection even more. His teeth silently ground in the back of his mouth, trying not to give in to the pleasure. Suddenly he felt all her fingers rake down his stomach. His whole body clenched and he let out a startled gasp. "Answer meeee…" she sang, and repeated the motion with her hands.

Tyler coughed out a brief laugh. It tickled. Bad. And while the feeling made him squirm to try and get his abs away, it sent the blood rushing down between his legs. She did it again, and he shook his head, "S-stop it…"

"Aww, are you ticklish?" Before he could even comprehend an answer, her fingers were dancing all over his stomach, his chest, his sides. She was practically riding a bucking bull as much as he thrashed against her touch. Sure, he might have been ticklish normally… But now he felt more sensitive than he ever had before. His head was tingling, his breath a literal pant. He cried out for her to stop again.

"Okay okay," she soothed. "I'll ask again… Ass or tits?" A brief pause, and she dug her thumbs into the creases of his pelvic bone. "I'll tickle again…"

He swallowed. "Okay, okay… tits. Happy?"

She smiled triumphantly. "I kinda thought so…" She reached one arm behind her. "So whose are better? Mine or Maddie's?"

He knew his girlfriend despised being called that. Fucking bitch. Fucking hot bitch.

"Still no answer huh?" She flexed her fingers in front of him devilishly.

"I- I dunno…" he stammered instantly. The thought of being tickled again mortified him. He could feel the pre-cum leaking against the insides of his shorts… He was glad the material was thick enough to hide it.

"What's the problem? Just be honest with me… It's not like I'll get mad or anything…"

Yeah, the hell you wouldn't. "I just…" his mind raced for an excuse, "…never thought about it." God. Lame.

She raised her eyebrows in disbelief. "Tyyyy-ler… I don't know if I believe you. But since I kind of like you… I'm going to give you the benefit of the doubt. So what we're gonna do, right now, is think about it." Her hand reached behind her, and with effortless movement, untied the knot of the cloth behind her neck. The cloth fell forward off of her chest and landed on Tyler's stomach.

His mouth felt instantly dry as he stared up at her naked tits.

She brought her hands up to them, and held them up a little… Let them drop back down. They bounced slightly. "So what do you think? I know they're bigger than hers… Do you like big tits or little tits?" she screwed up her eyes like she was concentrating overly hard.

Woah…

"Tyler?" she asked innocently.

"Yeah…"

She leaned over slightly, making them hang over his face. One of her hands steadied herself against the bars of the headboard. She subtly moved her other hand back to his stomach, walking two of her fingers along. "Answer me?"

He paused a little too long, and she dug back into his abs, tickling him again. He laughed and groaned at the same time. And shamefully, despite all of it, desperately pushed his hips up into her. Unabashedly trying to hump against her…

"Ummm- I'm not sure if this is having the right effect anymore!" she teased. "Do I have to find some other way to make you talk?"

"No! No… I like, uh- all kinds..." he panted as he caught his breath. "Just depends on the girl..." Okay, nice. That was good… It was a tiny victory.

"I'm not laughing, Ty-ler. We're not talking about some girl… We're talking about me… Right here!" she brought her hand off the bedpost momentarily to swat the top of his head. "Now since you're apparently too dense to make a decision on your own… I guess you'll have to get a closer look…"

His eyes widened as he realized she was allowing her body to drop down, bringing her tits right to his face. "Now tell me… Do you like them? Look… Not even any tan lines…"

He stared mesmerized at her beautifully pale skin. Her nipples stood out invitingly… Is she horny? Does she actually get off on this?

"I hate tan lines… I know Maddie has them… She goes through all that effort for that silly tan, and then you get her naked… It's like a funny tattoo or something… Don't you like this better?" her voice was low. Seductive. "Why don't you try a taste… Just a little kiss…" she leaned down lower, one nipple grazing his lips.

"A-Amber…"

"It's okay, Tyler… Nobody has to know…"

Would she tell Madison…? "I can't…" He was clinging to his last shred of dignity.

"Come on, I'm begging you… It's not like you have a choice… right? If I'm making you do it… It's not wrong…" She intentionally pushed her ass backward into his erection again, eliciting a hiss of delight from him. And then he lost it. He gave her a tender kiss on her breast. And with one, came another. And another.

"Yeah… Kiss them all over… You can lick too…" she moved her chest side to side, forcing him to alternate his attention between her tits. "Don't forget this one… Mmm… So have you decided yet, Tyler? Do you like mine more?"

In an attempt to not answer, he let out his tongue and began to enthusiastically lick across her nipple. She gasped out, "Ohhhh Tyler!" He had no will to stop his efforts with that kind of encouragement… And Amber's lips melted into a sultry, open-mouthed smile and she tilted her head to the side and stared directly into the camera.

XI

Madison had never been so confused in all her life. She knew she should be furious. Sick. Hurt. She watched her boyfriend squirm under her step-sister… His lips and tongue never leaving her breasts, her nipples. His hips rolled against the bed, trying desperately to push his unabashed erection against his shorts, against her. And now, on top of everything else, she knew her sister was mocking her… She looked into the camera right at her as she moaned…

But Madison couldn't stop moaning herself. Becca was propped up on her knees in front of the chair, her hands running all over Madison's stomach, sides, chest… She had already completely pulled away her bikini top. As soon as they watched Amber undress herself on the monitor, Becca cooed, "That looks like a good idea…"

Madison whispered pleas of resistance, but she knew it was pointless. And once she felt the first kiss against her nipple, her eyes rolled in her head from the velvet electricity that washed through her. "Uhnn… Please… B-Becca… I can't…"

A tongue rolled over her left breast and warm lips enveloped her, sucking earnestly. Then she felt teeth gently nibble her achingly hard nipple. She cried out as the buzz made her body buck against the chair. Becca responded by gently holding her hips in place. "Well I love your breasts…" she reassured her. "And I know you love the way I'm making them feel right now…"

"Please…" Madison uttered, not knowing exactly what she was asking for.

"Did you ever think another girl could touch you like this? To make you feel this?" she began kissing all over her stomach, giving her long licks up the length of her abdomen and back up to her chest, worshiping her upper body. "I'll do this whenever you want, Madison. You would be surprised at the things I'd do."

"Have… a boyfriend…" she resisted.

Becca pulled herself up so her face met Madison's. "I can share…" And she pushed their lips together, forcing a kiss onto her. Madison didn't know how to react. She didn't kiss back, but she didn't stop her. "Besides," she continued after breaking off, "Don't you know that girls can always do it better? We understand… Boys are helpless…"

Madison was having a terrible time focusing on anything. Part of her desperately wanted to watch the computer screen and see what her step-sister was doing to her boyfriend. And yet still, it was hard to watch, she wasn't convinced she wanted to know… To have those images stuck in her head. And then there was Becca, who wouldn't stop attacking her body. I'm not a lesbian… I'm not gonna turn into one… Why won't she stop…? She couldn't… wouldn't admit how good it felt. She tried to ignore it. Her body was on fire though. And finally when her captor gave her a few moments to relax and catch her breath, when the sensations had a chance to die down and let her regain some control… She realized she was getting wet. Oh my god. Oh my god. Oh my god.

"Stop…" she whimpered.

Becca sighed, and then tisked, "Why? Do you wanna be the only one not feeling good right now? I'm not gonna let that happen, baby..." She stood up and gave her some space. "You need to loosen up a little. I know there's a minx inside you just dying to get out." Her eyes roamed around the room. "Let's see… You must have a little friend somewhere in here…"

What is she talking-- Oh no…

"Now if you're anything like me, you want it close by." She walked behind the chair towards the bed. "Let's check the nightstand first…"

Madison tried to crane her neck to watch her, but it was no use. She immediately began to blush. Please don't find it… With nothing else to look at, she returned her attention to the monitor. Amber had finally leaned back up and stopped forcing (or at least Madison liked to think of it as forcing) Tyler to… pay attention to her breasts. Her step-sister was breathing kind of heavy, and she couldn't help but notice the swell of her chest as it rose and fall. She knew her boyfriend was looking as well… Fucking bitch. No fair that she has boobs like that…

Becca called out. "Well nothing here yet… I guess you wouldn't want it too accessible, after all. What about under the bed though… Hmmm…"

Madison heard more rustling behind her. Fuck! She grimaced, shutting her eyes. What is she gonna do with it… God this is humiliating…

"If I knew you were so… enthusiastic… I would have done this even sooner…" she heard Amber through the speakers. "Now I'm gonna need to know…" she rolled onto her back, lying parallel to Tyler, "…whose pussy you like better too…"

Madison watched in horrific fascination as Amber brought her knees up to her chest and wrapped her thumbs down her panties, slowly pulling them down her legs. She lazily had her head turned to look at Tyler, and he was looking back at her… though Madison could only see the back of his head from this angle. Is he saying something to her?

"Ah ha!" Becca cried triumphantly. "I foooound something… It's little, and blue… and oh! It looks like it turns on!"

No, damn it, no!

Becca returned to Madison's side, holding a small blue vibrator in her hand, grinning from ear to ear. "I have one a lot like this… Well, I have a few different kinds," her eyes laughed, "but I'm pretty sure I know how you use this one."

"Please Becca… That's not- I mean- Just don't…"

She twisted the bottom of it and turned it on a low hum. "Trust me Madison. This is going to be amazing."

Madison's body shook with nerves. What if she's right… Whatever I took… It's made me… She swallowed hard, feeling sudden butterflies in her stomach, and a warmth between her legs. She was too busy watching Becca to notice Amber on the computer. Her step-sister was again smiling wickedly into the camera as she straddled Tyler once more—this time completely nude.

"I can't believe you've never seen a shaved one up close before!" she mocked him.

Tyler couldn't believe how far this was going. He was flushed with frustration… He'd never been so teased in his life. Why do I even bother pretending…? It's not like it wasn't obvious how turned on he was. At this point, he wasn't sure why he was resisting. If it was because of some loyalty to his girlfriend… because he didn't want to give in to Amber's games… because he just knew it was wrong?

She continued to hover over his face, giving him an unending view of her exposed slit. It glistened with wetness and his nostrils flared as he smelled her obvious arousal. "So do you like it this way? I'm sure you could ask Maddie… I mean, she at least trims, right?"

He refused to answer. She'd already asked if he likes girls clean shaven… His lame attempt to deflect the question earlier had only brought on this new humiliation. He sure as hell wasn't going to admit that he liked it…

"I guess a landing strip is okay," she mused to herself. "Becca had one for awhile… But I made her get rid of it. I just won't go down on a girl with any hair… I think once you try it like this, you'll agree with me."

She said it so nonchalant that the message almost went over his head. Oh fuck, she really is going to make me. This is so fucked up… He rolled his tongue in his mouth in guilty anticipation.

" Tyyyy -ler… You're not answering me again…" He suddenly felt her reach back and walk two fingers along his chest. She found the sensitive skin around his nipple and began lightly tickling. He jerked against his bonds and groaned. "You want to be tickled again? Don't think I'll stop so fast next time."

"No…" he groaned. Last time she tickled him, his entire body tingled from the hyperventilation and he began seeing stars. And when she was done, his cock actually hurt from being so goddamn hard. Fuck, it's still killing me… He had tried shifting his hips around in every possible direction, looking for some relief. When that didn't work, he tried to move in a way to feel good… That didn't help. What am I going to do? Make myself come in front of her?

She rolled down his body now, sitting again on his stomach. His abs felt the slickness between her legs rub onto him. "So do you like the way it looks?" she repeated.

Damn her. "Yeah."

She squealed with delight. "Better without hair?"

He paused a little too long, and she menacingly flexed her fingers above his chest. "Yeah."

"Yeah what? Yeah better?"

He sighed and nodded.

"Say it."

"Yeah better."

Her eyes fluttered closed for a minute and she bit her lip, rocking her body against his for a moment. "Reeeeally.... Say it again."

Twisted slut is getting off on this. "Yeah. Better," he repeated with sarcasm.

"Well then I guess there's only one last thing to find out… Between me n' Maddie, I mean." She reached out to the headboard, grabbed on, and slid up his body. "Wanna know what it is?" she cooed.

I know what it is. "Huh," he grunted neutrally.

"Don't you think we need to find out who… tastes better?" she trailed off to a whisper as she said it.

And with that her legs were rest on both sides of his head, her pussy hovering just inches above him. But this time, he knew it was coming, and coming soon.

"Are you excited?" she asked huskily from above him.

He didn't answer.

"Come on… Tell me."

I can't take this shit. Let's just do this. "If you want it, get down here."

She gasped. "Tyler! Come on… Don't you want it? Don't you want to know which pussy tastes better? Aren't you dying to find out?"

Gimme a break. "Still can't reach," he retorted as flatly as possible.

"Tell me you want it, or else."

He swallowed. I can't take any more torture. Fuck this, I can't take the bullshit either… I want this anyway… "I want it."

"Want whaaaat?" she teased.

"I want to taste it."

"Taste what."

"Taste your goddamn pussy!" he hissed.

"Mmm… That's a good boy…" she lowered herself down to Tyler's face.

He didn't waste any time. Without even thinking, he wrapped his mouth around her and laid his tongue flat against her slit. She let out a little gasp, and he continued by curling the tip of his tongue, back and forth, in and out. He lifted his head off the pillows and brought his attention up along the top edge of her, beginning then to suck between his lips.

She cried out at that. "Ah!... Yeah! Suck me, you bad boy… Eat me out… Taste me…"

Her dirty talk spurred him on. Somewhere in the back of his mind, he was rationalizing, if I can just make her come… She'll calm down. She won't want anything else. Maybe then I can go. But more than that, his lust was taking over. And even some of his anger. He wanted to make her come. He wanted to experience this… To teach her he wasn't just some toy, but someone that could really get her off.

So he gave her his all. He dove his tongue as far into her as he could, tried to fuck her with it. He licked everywhere he could reach, sucked along every inch of her sex. He kissed her slit, the inside of her thighs, blew on her, and dove back in. She moaned, giggled, cooed… Her body rocked against him, and her legs would tense up and tremble whenever he did something she liked.
