In the dimly lit room, Leo's eyes feast on Sara's sleeping form, her big, round ass and large tits rising and falling with each breath. His cock throbs in response, tenting his pants. He reaches out, his hand trembling as he gently cups her ass, feeling its firmness. Sara stirs, her hips shifting slightly, and Leo's breath hitches. He can't help but imagine her waking up, finding him there, and giving in to their mutual desire. His other hand moves to his cock, stroking it slowly, the fabric of his pants growing damp with pre-cum as he fantasizes about fucking his friend's wife while she's still half-asleep.
