The house was dead quiet after midnight, the kind of silence that made every small sound feel loud. Jenna stood in the hallway outside her brother's room, her heart pounding in her chest. At twenty-four, she knew better. She had always known better. But the urge had been building for weeks, and tonight it had finally won.
She eased the door open. The room smelled like himclean soap, warm skin, and a hint of the cologne he wore during the day. Mark lay on his back in the middle of the bed, one arm thrown above his head, the sheet twisted low around his hips. He was shirtless, the hard planes of his chest rising and falling with deep, even breaths. He had worked a double shift and taken a couple of the sleeping pills the doctor gave him for his back. Jenna had watched him swallow them hours ago. He would not wake easily.
Her bare feet made no sound on the carpet. She moved closer, eyes fixed on the bulge beneath the thin sheet. Her mouth watered. She had thought about this exact moment so many times that the reality of it felt almost unreal. Slowly, carefully, she hooked two fingers under the sheet and drew it down.
Mark's cock lay heavy against his thigh, half-hard even in sleep. Thick, veined, the head a darker shade than the shaft. Jenna's breath caught. She had seen it once before, years ago, when they were both younger and careless with doors, but never like thisnever soft and available and so close she could smell the faint musk of him.
She climbed onto the bed, moving with exaggerated care so the mattress barely shifted. Straddling his thighs, she leaned down. Her long hair brushed his stomach. She wrapped her fingers around the base of his cock and lifted it. Even soft it was substantial, warm and alive in her palm. She stroked once, slow and gentle, feeling it twitch and begin to fill.
Mark didn't stir.
Jenna brought her face closer. She dragged the flat of her tongue from the base all the way to the head, tasting salt and skin. The taste made her thighs clench. She did it again, slower, wetting him thoroughly before closing her lips around the head and sucking.
A soft, involuntary sound escaped her throat. She took more of him, relaxing her jaw, letting the weight of his cock rest on her tongue. Inch by inch she worked him deeper, feeling him swell and harden inside her mouth. When he was fully erect, the head nudging the back of her throat, she pulled off with a wet pop and admired her workglistening, flushed, veins standing out.
She went back down. This time she used her hand at the base, stroking in time with the bob of her head. Saliva ran down his shaft and over her fingers. She hollowed her cheeks and sucked hard, the obscene wet sounds loud in the quiet room. Every few strokes she paused to lick around the crown, flicking the sensitive spot underneath with the tip of her tongue.
Mark's breathing changed, growing slightly heavier, but his eyes stayed closed. His hips gave one tiny, unconscious thrust upward. Jenna moaned around him, the vibration making his cock jerk. She took him deeper, gagging softly when the head pushed into her throat, then swallowed around it. Tears pricked the corners of her eyes, but she didn't stop.
She lost track of time. The only things that existed were the stretch of her lips, the heavy weight on her tongue, the way his balls tightened when she cupped them. She alternated between slow, deep sucks and quick, shallow ones, using her hand to keep the rhythm steady. Precum leaked steadily now; she licked it up greedily, savoring the bitter taste.
Her free hand slipped between her own legs. She was soaked. Two fingers slid easily inside her pussy while she continued sucking him. The dual sensation made her whimper. She fucked herself slowly, matching the movement of her mouth on her brother's cock.
Mark groaned in his sleep, low and rough. The sound shot straight to Jenna's clit. She sucked harder, faster, determined to make him come without waking him. Her cheeks hollowed, her hand pumped the base, and her tongue worked the underside with every stroke.
His cock swelled even thicker. His balls drew up tight. Jenna knew he was close. She sealed her lips just below the head and sucked rhythmically, milking him. The first pulse hit her tonguethick, hot, salty. She swallowed without pulling off, taking every spurt he gave her. Some escaped the corner of her mouth and ran down his shaft; she licked it up afterward, cleaning him with long, slow strokes of her tongue until he began to soften.
Only then did she ease off. She sat back on her heels, breathing hard, lips swollen and shiny. Mark's cock lay against his stomach, wet and spent. His chest rose and fell in the same deep rhythm as before.
Jenna wiped her mouth with the back of her hand. She pulled the sheet up over him again, tucking it gently around his hips. For a long moment she simply watched him sleep, the taste of him still on her tongue.
Then she slid off the bed, silent as she had come, and left the room, closing the door behind her with a soft click. Her body hummed with satisfaction and the lingering thrill of what she had done. She already knew she would be back another night.
