Chapter 1: The Unexpected Ride
The air in the bathroom was thick and damp, clinging to Liam’s skin like a second layer. He sat on the closed lid of the toilet, his jeans and boxers bunched around his ankles. The only light came from a dim bulb above the sink, casting long shadows across the cool, slick tiles. His breath hitched, a soft, rhythmic sound lost under the faint drone of the bathroom fan.
His hand moved on his cock, a steady, practiced stroke. His eyes were closed, head tilted back against the cold tank. In his mind, it was vague, blurred images of curves and whispered sounds, but lately, those blurred images always sharpened into a specific face, a specific smile. He tried to fight it. He’d been fighting it since he got back from school. The confusion was a live wire in his gut, sparking every time she laughed or brushed past him in the hall.
Precum beaded at his tip, glistening. He swore under his breath, his pace quickening. The finish was close, a tight coil in his abdomen ready to snap. He just needed a few more seconds.
The door pushed open.
It didn’t click or creak. It just swung inward, silent on its hinges. The steam from his shower hadn’t fully cleared, and she appeared through it like a phantom. Evelyn. Her long auburn hair was down, damp at the ends from her own shower. She wore just a thin, worn t-shirt and panties.
His hand froze. He couldn’t move, couldn’t breathe. Shame, hot and immediate, flooded him. He fumbled to cover himself, his mind screaming.
But she didn’t gasp. She didn’t turn away. Her piercing green eyes locked onto him, then dropped. They traveled down his lean torso, past the trail of hair below his navel, to where his cock stood, rigid and exposed in his stilled grip.
Her expression shifted. Not shock. Not anger. Something darker. Her lips, usually quirked in a mischievous smile, parted slightly. The confidence that always radiated from her seemed to condense, to focus into a single, hungry point.
“Fuck, Liam,” she said, her voice a low hum that vibrated in the cramped space.
“Evie—get out—” he choked out, but it was weak, a whisper.
She stepped in fully and let the door swing shut behind her. The click of the lock was deafening. She didn’t look away from him. Her gaze was a physical weight.
“Were you thinking about me?” she asked, taking another step. The tile was cold under her bare feet. “I always wondered.”
He couldn’t answer. His throat was sealed shut. He watched, paralyzed, as she closed the distance. The scent of her shower gel—something clean and lemony—cut through the mildew of the room.
She stopped right in front of him. Her eyes were level with his now. Slowly, as if she had all the time in the world, she reached out. Her fingers didn’t go to his face. They brushed his wrist, the one still clumsily trying to hide his erection. She pushed his hand away.
He let her.
Her touch was electric. Her fingers traced the vein on the underside of his cock, a feather-light stroke that made his whole body jolt. A soft, ragged moan escaped him, betraying everything.
“Yeah,” she murmured, almost to herself. “You were.”
Then her hands went to the hem of her shirt. In one smooth motion, she pulled it over her head and dropped it on the damp floor. She wasn’t wearing a bra. Her breasts were full, her nipples taut in the cool air. He’d seen her in bikinis a thousand times, but this was different. This was for him.
Without breaking eye contact, she hooked her thumbs into the sides of her panties and pushed them down her thighs, stepping out of them. She kicked them aside.
His brain short-circuited. Every moral boundary, every line they’d ever known, dissolved in the steam between them. All that was left was raw, pounding need.
“Evie…” It was a plea, but for what, he didn’t know. For her to stop. For her to never stop.
She didn’t say another word. She placed her hands on his shoulders. Her skin was so warm. Then she lifted one leg, hiking her knee over his hips, straddling him on the toilet seat. The position was awkward, cramped, desperate. The cold porcelain bit into the backs of his thighs.
He felt her heat against him. She was wet. Soaked. The proof of her desire slicked his skin as she rubbed against him, not taking him inside, just grinding her clit against the length of his shaft, her breath coming in short, sharp puffs against his neck.
“Fuck,” he groaned, his hands coming up to grip her hips, his fingers digging into the soft flesh there. He was trembling.
She reached between them. Her hand wrapped around his cock, guiding him. She positioned him right at her entrance. She paused, her forehead resting against his, their noses almost touching. Her green eyes were black with want.
“Tell me you want this,” she breathed.
“I want it,” he gasped. “God, Evie, I want it so much.”
She sank down.
It was a slow, devastating invasion. She was unbelievably tight, hot, clenching around him as she took every inch, her body swallowing his. He cried out, a broken sound that echoed off the tiles. His vision blurred at the edges. The feeling was beyond anything he’d ever imagined—wrong, filthy, perfect.
She didn’t give him time to adjust. Once he was fully seated inside her, she began to move. Her hips rolled, then plunged. She set a brutal, driving rhythm from the start, using her thighs for leverage, fucking herself on him with a focused, animal intensity.
The room filled with the sounds of it. The wet, slick slap of skin meeting skin. The creak of the toilet seat protesting under their combined weight. Their ragged, shared breaths, punctuated by guttural moans.
“You feel that?” she hissed, her nails scraping down his back. “You feel how deep you are?”
“Yes,” he grunted, his own hips meeting her thrusts, driving up into her. The angle was intense, hitting a spot inside her that made her eyes roll back every time he bottomed out.
“This is your sister,” she whispered, her voice dripping with a perverse triumph. “This is my little brother’s cock buried in my cunt. You like that? You like fucking your sister?”
The words should have horrified him. They did. And they fucking destroyed him. They stripped away the last pretense, naming the sin, making it real. It pushed him higher.
“Yes,” he snarled, his hands sliding down to grab her ass, squeezing hard, spreading her open for him as he pistoned up into her. “Your cunt is so fucking tight. Made for me.”
She moaned, long and loud, throwing her head back. The column of her throat was exposed, and he leaned forward, biting down on the tender skin there, not hard enough to break it, but hard enough to claim it. She shuddered, her inner muscles clamping down on him rhythmically.
He was losing control. The coil was at its breaking point, a white-hot pressure at the base of his spine. His balls drew up tight.
“I’m gonna come,” he warned, his voice strained.
“Do it,” she commanded, her pace becoming frantic, slamming down onto him. “Come inside me. Fill me up. I want to feel it.”
That was all it took. His orgasm tore through him like a lightning strike. It was violent, convulsive. He buried his face in the curve of her neck to muffle his roar as he erupted, pulse after hot, thick pulse emptying deep into her. His hips jerked uncontrollably, fucking his seed up into her clutching heat.
She rode him through it, milking him with fierce, rolling contractions of her own body. Then, as his spasms began to subside, she let out a sharp, choked cry. Her body went rigid above him. He felt her flutter and spasm around his still-hard cock, a second, wetter wave of heat joining his own as she came, her inner walls gripping him in a rhythmic, pulsing vise.
For a long moment, there was only the sound of their heavy breathing and the drip of the showerhead. The steam had cleared. The mirror above the sink was fogged, reflecting only a blurred, tangled shape of two bodies fused into one.
Slowly, the world came back. The cold of the seat. The ache in his thighs. The stunning, devastating reality of what they had just done.
He was still inside her. She was still draped over him, her skin slick with sweat, her head on his shoulder. Her breath fanned across his collarbone.
She shifted, finally lifting herself off him with a soft, wet sound. She stood on shaky legs, not looking at him. She picked her shirt up from the floor, pulled it on. It did nothing to hide what had just happened. She found her panties, stepped into them.
He sat there, exposed, spent, his mind a numb void. His own release was already leaking out of her, a stark, physical truth on her inner thigh before she covered it. He couldn’t form a single thought.
Evelyn turned to the sink. She splashed cold water on her face. She caught his gaze in the mirror. Her expression was unreadable—a mix of sated pleasure, deep shock, and something else. Something like fear.
Without a word, she unlocked the door. She paused, her hand on the knob, her back to him.
“Clean yourself up,” she said, her voice flat, drained of its earlier heat. Then she was gone, the door shutting quietly behind her.
Liam was alone. The bathroom felt huge and empty and freezing. He looked down at himself, at the mess glistening on his stomach and his soft, damp cock. The smell of sex and her and his own shame was overwhelming.
He didn’t move for a long time.
