In the dim light of their shared bedroom, Patrick and his stepsister, both clad in thin, cotton pajamas, find themselves unable to sleep. Her nipples harden against the fabric, betraying her arousal as she catches him staring. Patrick shifts uncomfortably, his erection tenting his pants. They've danced around their forbidden attraction for too long. Tonight, they give in, their hands exploring, their breaths ragged. She straddles him, grinding on his cock as they feverishly kiss, their bodies pressed together, sweat mingling.
