章 23: sisters want to know who's ass is better
"Mom's out for the whole afternoon," Becky announced, her voice echoing through the hallway of their suburban home. She peered into the living room where her brother, Tim, was lost in a video game, the glow of the TV reflecting off his glasses. "You busy?"
Tim grunted, his eyes flickering up briefly before returning to the digital battlefield. "Nah, what's up?"
Becky stepped closer, her twin sister, Laura, appearing in the doorway behind her, both of them wearing hopeful expressions. "We need your...honest opinion on something," Laura began tentatively.
Tim's thumbs paused over the controller, curiosity piqued. "Okay, lay it on me."
Becky and Laura exchanged glances, a silent agreement to proceed. Laura took a deep breath and asked, "So, Tim, who do you think has the better butt? Me or Becky?"
Tim's eyes widened, his character frozen mid-attack on the screen. "What?!" he exclaimed, his voice cracking with surprise. He lowered the controller, his gaze darting between the two girls. "You guys are serious?"
Becky nodded, her cheeks flushing a light pink. "Yeah, we had this bet, and we want an honest answer." Laura mirrored Becky's nod, her expression earnest.
Tim stared at them, his mouth agape. "Guys, seriously?" He leaned back in his chair, trying to process the sudden shift in conversation. "I mean, you both have...uh, nice...butts," he stammered, realizing he had just stepped into a minefield of sibling rivalry.
Without a moment's hesitation, Becky plopped herself onto Tim's lap, facing him. Laura rolled her eyes but followed suit, sitting on the armrest of the chair, her own posterior just a few inches away. "C'mon, Timmy," Becky coaxed, "just tell us the truth." Laura leaned in, her competitive spirit undeterred. "We won't get mad, promise."
Tim's heart raced as he found himself trapped between their expectant gazes and the pressure of their bodies. He could feel the tension in the room thicken as they both waited for his response. He took a deep breath, trying to calm the flurry of thoughts in his head. "Okay, okay," he said, "but remember, this is just my opinion." He paused, his hands hovering awkwardly in the space between them, unsure of how to proceed without causing an explosion.
Finally, he decided that the best approach was to be as neutral as possible. "Could you guys, maybe, stand in front of me?" he suggested, his voice a little shakier than he would have liked. Laura and Becky looked at each other, then shrugged in unison. They both turned around, presenting their backsides to Tim. He swallowed hard, his eyes darting back and forth between the two, trying to compare them objectively.
"Okay, hold on," he said, his mind racing. "How about you both take off your shorts, so I can get a better look?" Laura raised an eyebrow but did as he asked, sliding her shorts down to her ankles and stepping out of them. Becky followed suit, a smug smile playing on her lips. Tim's cheeks burned as he took in the sight of their underwear-clad bottoms.
He got up and pushed their asses side by side, trying to maintain a poker face. The soft fabric of their panties stretched tautly across their curves, leaving little to the imagination. Laura's butt was rounder, with a subtle dimple at the top of her cheeks, while Becky's was more toned, a result of her recent obsession with yoga. Tim felt his palms start to sweat as he placed one hand on each, trying to feel the muscle tone and firmness. Laura giggled nervously, her body trembling slightly. Becky remained stoic, her eyes locked on Tim's face, daring him to choose.
"It's a pretty hard decision," Tim murmured, his voice thick with tension. Laura's giggles turned into a full-blown laugh, the absurdity of the situation finally getting to her. Becky's expression grew more determined, leaning into the competition.
"Come on, Timmy," Becky said, her voice a seductive purr. "We really want to know. What do you say we make it even more...interesting?" She reached back and slid her fingers into the waistband of her panties, pulling them down just enough to reveal the top of her ass crack. Laura's eyes went wide, her laughter dying in her throat.
Tim's eyes shot up to meet Laura's, which were now full of panic. "Becky, what are you doing?" Laura whispered harshly.
"What? You scared you won't win?" Becky taunted, a smirk playing on her lips. Laura's competitive spirit kicked in and she decided she wasn't going to be outdone. With a huff, she reached back and mirrored Becky's action, pulling her own panties down to the same revealing level. The tension in the room grew palpable as Tim found himself face-to-face with the tops of their bare asses.
"Okay, okay," Tim managed to say, his voice hoarse with the effort of remaining calm. He took a step back, trying to clear his head. "I'll...uh, I'll test them both." He approached Becky first, his hand hovering over her now exposed skin. He gave her a gentle squeeze, feeling the firmness of her muscles and the softness of her flesh. Becky bit her lip, suppressing a gasp as his fingers lingered a moment too long. Tim then moved to Laura, his hand shaking slightly as he repeated the action. Laura's ass felt different, softer yet equally appealing.
"But that's not fair," Laura protested, her voice laced with a mix of embarrassment and determination. "You have to actually see them side by side." Becky nodded in agreement, a mischievous glint in her eye. "Yeah, Timmy, come on. This is a real competition," she teased.
Without waiting for Laura's response, Becky hooked her thumbs into the waistband of her panties and slid them down, letting them fall to the floor. She stepped out of them, turning around to face Tim with a smirk. Laura's jaw dropped at Becky's audacity, but she knew she couldn't back down now. With trembling hands, she did the same, her cheeks burning as she stepped out of her underwear. They were both now fully exposed, standing before their brother in just their t-shirts and there asses bare.
Tim felt his heart hammering in his chest, his mind racing with a mix of excitement and dread. He couldn't believe what was happening, but he knew that if he didn't play along, the situation could turn sour. He took another step back, his eyes darting between the two naked asses presented before him. Laura's was more of a peachy color, with a smoother texture, while Becky's was slightly tanned and had a more athletic look.
"Alright," Tim said, his voice barely above a whisper. "But remember, I'm just...trying to be helpful." Becky winked at Laura, who rolled her eyes but remained silent. "Okay, then," Becky said, turning around and bending over, placing her hands on her knees. Laura did the same, both of them presenting their bare bottoms to Tim. "Now, test us like a man would," Becky instructed, her voice dripping with challenge.
Tim took a deep breath, trying to ignore the blood rushing to his groin. He approached Becky first, his eyes focused solely on the task at hand. He placed his palms on her ass cheeks and gave them a firm squeeze, his cock swelling in his pants. Laura's ass was next, and he couldn't help but notice the difference in texture. "Mine's definitely firmer," Becky said with a smug look over her shoulder. Laura shot her a glare, but Becky just shrugged.
Feeling the heat rising in his face, Tim took another step back, his pants now painfully tight. He decided to follow Becky's lead and get fully naked, his heart racing as he pulled off his shirt and unbuckled his belt. His cock sprang free, thick and hard, pointing straight at the two bare asses before him. Laura and Becky both gasped, their eyes widening at the sight of their brother's nakedness. Laura looked away, her cheeks burning, but Becky's gaze remained locked on Tim's cock, a smoldering curiosity in her eyes.
"Okay, then," Becky said, her voice a little more sultry than before. "Who's first?" She turned around and bent over the arm of the couch, her ass in the air. Laura, trying to keep up, did the same, her pussy glistening slightly with arousal. Tim's cock twitched as he approached Becky, his hand reaching out to touch her ass once more. He slid his hand down, feeling the smoothness of her skin and the slight dampness between her cheeks.
"I-I can't," Laura stuttered, her eyes glued to Tim's cock. "This isn't right." But Becky just chuckled, her voice low and seductive. "Don't be such a prude, Laura. It's just us, and we're all adults here."
Tim took another step closer, his cock bobbing with the movement. He placed his hand on Becky's ass again, this time letting his thumb brush against her anus. Becky gasped, her body tensing. Laura's eyes grew wide, watching everything unfold. "What are you doing?" she whispered, her voice barely audible.
Ignoring Laura's protest, Tim leaned in, his cock nudging against Becky's pussy. Becky looked back at him, her eyes full of a mix of excitement and trepidation. "Are you sure about this?" she asked, her voice a sultry whisper. Tim nodded, unable to find the words to express the tumult of emotions coursing through him.
With a deep breath, he pushed into Becky, feeling the tightness of her pussy envelop him. She gasped, her body arching back to meet his. Laura's eyes widened even further, and she took a step back, unsure of what to do next. Becky's moan filled the room as Tim began to move, his hips thrusting gently into her, savoring the sensation of their flesh connecting. Laura's own arousal grew as she watched, her hand unconsciously drifting to her clit, her legs shaking with the effort of keeping her balance.
Becky's prideful gaze never left Laura's face, a silent challenge that seemed to say, "Look what I've got." Laura felt the heat of their sibling rivalry intensify, her own body responding in ways she didn't understand. Despite her reservations, she found herself moving closer, her hand slipping into her own shorts to mimic Tim's actions on Becky's ass. She watched as Tim's hand slid down Becky's back, his fingers dipping into her crack, and she felt an unexpected surge of jealousy and excitement.
With trembling fingers, Laura began to stroke her own pussy, her eyes flicking between Becky's face and Tim's cock. She couldn't deny the thrill of watching her brother take her sister, the forbidden nature of it all making her wetter than she had ever been. Becky's eyes widened when she felt Laura's touch, and she turned her head to look at her sister, her smile turning into a sultry smirk.
"What's the matter, Laura?" Becky purred, her voice filled with mock innocence. "Can't handle watching Tim choose me?" Laura flushed, her hand moving faster over her clit. "It's...it's not fair," she managed to say between gasps. "You're supposed to be getting him to choose, not...this."
Tim's hips began to move faster, his cock driving into Becky with increasing fervor. She moaned loudly, pushing back against him, her breasts bouncing with each thrust. Laura couldn't help but watch the erotic display, her own body responding in ways she never thought possible. The sound of skin slapping against skin filled the room, the rhythmic thud echoing in Laura's ears.
"Bet you Becky won't let him cum inside of her," Laura said suddenly, her voice a little shakier than she intended. Becky looked over her shoulder, her eyes narrowing.
"What? You think you're better than me?" Becky's voice was laced with challenge. Laura swallowed, her hand still moving over her clit. "I'll do it," she said, surprising even herself. "I'll let him cum inside of me."
Tim's eyes shot to Laura, his strokes slowing for a moment before he regained his rhythm. The idea of his sisters fighting over who could take his cum was too much to handle, and he felt his orgasm approaching rapidly. Laura stepped closer, her own hand slipping into her shorts to masturbate in time with Tim's thrusts into Becky. The sight of her brother's cock disappearing into Becky's pussy, her juices coating his shaft, was more arousing than she ever thought possible.
Becky sensed Tim's impending climax and pushed back against him even harder. "Do it," she breathed, her eyes glazed with lust. "Cum inside me. Prove I'm the better one." Laura's hand stilled at the words, a mix of anger and excitement coursing through her. She wanted to win this twisted game, but watching Tim fuck Becky was driving her wild.
With a strangled groan, Tim gave in to Becky's demand. He drove his cock deep into her, the head brushing against her cervix. Becky's eyes rolled back in her head as she felt the warm flood of his semen fill her up. Laura's eyes were glued to the sight, her own arousal reaching a peak as she watched the taboo act unfold. "Oh, fuck," Becky moaned, her body shaking with the intensity of her orgasm. Tim's grip tightened on Becky's hips as he pumped into her, his sperm painting the inside of her pussy with every stroke.
Laura felt a strange mix of defeat and arousal wash over her as she watched Becky's victory. Her hand remained buried in her shorts, her own orgasm building as she stroked herself faster. "You gonna lose," Becky panted, her eyes locked onto Laura's. Laura's cheeks flushed, her body trembling with the effort of not giving in to Becky's taunts. She clenched her teeth, her eyes narrowing
.
As Becky's moans grew louder, Laura's resolve to resist the overwhelming sexual energy in the room began to waver. Her hand moved faster over her clit, her breaths coming in quick, shallow gasps. She could feel the heat of Becky's victory, the smugness radiating from her sister's body as she claimed Tim's cum. Laura knew she couldn't let Becky win so easily.
With a sudden surge of courage, Laura stepped forward, her own ass now presented to Tim. She bent over, her cheeks spreading slightly as she offered herself to him. "Take me," she whispered, her voice barely audible over Becky's cries of pleasure. Tim's eyes widened, his cock still hard despite his recent climax. Laura's pussy was soaking wet, the evidence of her arousal glistening on her inner thighs.
Tim pulled out of Becky, her cum-filled pussy making a wet sound as they separated. He stepped over to Laura, his eyes never leaving hers. He positioned himself behind her, the head of his cock brushing against her slick folds. Laura held her breath as he pushed inside, feeling the stretch of her sister's recent use. The sensation was strange and thrilling, and Laura couldn't help but moan at the feeling of being filled by their brother's cock.
Tim began to thrust into Laura with a ferocity that surprised them both. The room was filled with the sound of wet flesh slapping together, his balls smacking against her ass with every plunge. Laura's eyes rolled back in her head as she felt him hit that perfect spot inside her, the same spot Becky had enjoyed moments ago. She couldn't help but let out a series of whimpers that grew into cries of pleasure.
The purpose of their bet, the competition over who had the better ass, was forgotten as the three of them became lost in the raw, carnality of the moment. Laura felt Becky's eyes on her, watching the rapture play out on her face. She knew Becky was probably seething with jealousy, but she didn't care. All Laura could focus on was the feeling of Tim's cock moving in and out of her, the way he filled her up completely.
Tim's hips slammed into Laura's ass, each thrust sending a bolt of pleasure through her body. Her legs trembled, her pussy tightening around him as she approached her climax. Laura's mind was racing, thoughts of Becky's earlier victory fading as she felt her own orgasm building.
Becky watched from the sidelines, her own body still trembling from her recent climax. She felt a twinge of jealousy as Laura's moans grew louder, but she couldn't deny the thrill of seeing Tim's cock disappear into Laura's pussy. Laura's body was tensing, her back arching as she reached the peak of pleasure. Tim groaned, his eyes squeezed shut as he felt his orgasm approaching.
With a grunt, Tim's body stiffened, and he began to pump his cum into Laura's welcoming womb. Laura's walls clenched around him, her orgasm crashing over her like a tidal wave. She screamed, the sound echoing through the room as she felt the warmth of his semen fill her. It was unlike anything she had ever felt before, the raw, primal sensation of being claimed by her own brother.
Becky watched, her own orgasm subsiding as she took in the sight of Laura's face, contorted in pleasure. She felt a strange mix of emotions—desire, jealousy, and a twisted sense of pride. She had pushed Laura to this point, had driven the competition to this taboo conclusion. And now, as Laura's body quivered with the aftershocks of her climax, Becky knew that she had won.
Tim pulled out of Laura, his cock still glistening with their combined juices. Laura stood up slowly, her legs wobbly, and pulled her shorts back up, trying to regain some semblance of dignity. Becky couldn't resist the urge to strut over to Tim, her own bare ass swaying with each step. "So, Timmy," she said, her voice a sultry purr, "who's the winner?"
Tim's face was a picture of bewilderment, his mind racing as he tried to process the events of the last few minutes. "I...uh, I can't...it's not about that," he stuttered, desperately trying to avoid choosing between his sisters. Laura's cheeks were still flushed, but she nodded in agreement, the sexual haze slowly lifting from her eyes.
"It's okay, Tim," Becky said, her voice still heavy with lust. "You don't have to choose. We're both winners here." Laura shot Becky a glare, but Becky just winked, her confidence unshaken. "Besides," Becky continued, her hand sliding down to cup her own ass, "I think we've both proven that we know how to handle what you've got."
