In the heart of a bustling party, Julia Reaves and her brother slip away, seeking a moment of privacy in a cramped, dimly lit bathroom. As they stand side by side at the sink, their eyes meet in the mirror, reflecting the unspoken tension between them. With a sudden, bold move, Julia reaches out, her hand finding its way to her brother's crotch, firmly grasping his growing erection through his pants. He stiffens, but doesn't pull away, his breath catching as he leans into her touch.
