The door to the basement rec room was cracked open just enough for light to spill across the hallway carpet. Lena had come downstairs for a glass of water and stopped dead when she heard the low, wet sounds. She knew that voiceher older brother Markbut the other one was unfamiliar, deeper, rougher. She pressed closer, one eye to the gap, and froze.
Mark was on his knees on the old leather couch, shirtless, jeans shoved down to his thighs. His mouth was stretched wide around another man's thick cock. The strangertall, broad-shouldered, maybe a gym buddyhad both hands in Mark's hair, guiding him slow and deep. Every time Mark pulled back, saliva glistened along the shaft before he sank down again, cheeks hollowing, throat working visibly. The wet, obscene sounds filled the room: slick suction, soft gagging, Mark's low moans vibrating around the length.
Lena's breath caught. Heat flooded her face and then lower, pooling between her legs. She had never seen her brother like thiseager, submissive, eyes half-lidded with pure lust. His own cock hung heavy and leaking between his spread thighs, untouched. The stranger groaned and thrust deeper. "Fuck, that's it. Take it all the way." Mark's hands gripped the man's hips, pulling him in until his nose pressed against skin. He held there, throat convulsing, then pulled off with a gasp, strings of spit connecting his lips to the swollen head.
"Again," Mark rasped, voice wrecked. He licked a long stripe up the underside before swallowing him once more. His head bobbed faster now, messy and hungry. The stranger's abs flexed, one hand tightening in Mark's hair while the other reached down to pinch a nipple. Mark moaned louder around the cock, hips rocking forward like he needed friction.
Lena's fingers slipped under the waistband of her shorts without thinking. She was soaked. Two fingers slid through her folds as she watched Mark work that cock like he was starving for it. Every slurp, every choked breath made her clit throb. She circled slowly, matching the rhythm of her brother's mouth. The stranger started thrusting, fucking Mark's face in steady strokes. Mark took it, eyes watering, drool running down his chin onto his chest. He looked blissed out, cock twitching untouched.
The stranger pulled out suddenly, stroking himself. "You want it on your face or down your throat?" Mark opened his mouth, tongue out, and the first thick rope landed across his tongue and lips. More followed, striping his cheek and jaw. Mark swallowed what he could, then licked the head clean while the man shuddered above him.
Only then did Mark glance toward the door. His eyes locked on Lena's through the crack. He didn't look surprised. A slow, filthy smile curved his cum-smeared mouth. "You can come in if you want," he said, voice hoarse. "Or keep watching. Either way, I'm not done."
Lena pushed the door open. The stranger turned, still hard, and Mark stayed on his knees, waiting. She stepped inside, shorts already pushed down, and closed the door behind her. The night had only just begun.
