In the stifling heat of a shared room, a brother and sister, both restless and frustrated, find solace in self-pleasure. The sister, Michelle, tentatively touches herself, her fingers exploring her wetness as she imagines her brother's thick cock. Her brother, overhearing her soft moans, joins her, his own hand working his hard length. Their eyes meet, and the tension between them grows palpable. They decide to indulge in their taboo desires, Michelle's hands wrapping around her brother's cock, feeling its heat and size. They explore each other's bodies, their breaths coming in ragged gasps, until they're interrupted by a knock at the door, forcing them to hastily separate.
