Incestuous siblings ignite forbidden desires

A brother and sister, trapped together in a small room, can't resist the electric tension between them. They start with stolen glances at each other's bodies, the sister's nipples hardening under her thin shirt, the brother's cock twitching in his jeans. As their breathing grows heavier, they succumb to their taboo fantasies, the sister straddling her brother, grinding on his lap before they're interrupted by a knock at the door.
