A brother and sister, trapped in the confines of their shared bedroom, give in to their primal urges. The sister, a temptress in her mini skirt, straddles her brother, grinding her wet pussy against his bulging jeans. He responds by palming her breasts, feeling her nipples harden through her thin top. They undress each other hurriedly, their hands fumbling with buttons and zippers. The brother's cock springs free, already rock-hard and eager. The sister takes it in her mouth, swirling her tongue around the head, tasting the pre-cum that's already leaking out. She guides him to her pussy, and they fuck like rabbits, their bodies slapping together, their moans filling the room.
