In the sweltering heat of summer, siblings Michelle and her stepbrother find solace in the cool darkness of their closet. As they huddle together, Michelle's hand brushes against her brother's growing erection. They freeze, eyes locked, before Michelle tentatively wraps her fingers around his throbbing cock. Her brother responds, cupping her breast, their breathing ragged. They explore each other's bodies, their curiosity and lust overwhelming their inhibitions. Michelle guides her brother's cock to her soaking entrance, gasping as he fills her. They fuck in silence, their bodies moving in sync, their climax echoing in the confined space.
