Confined to their tiny bedroom, siblings turn to each other for solace and release. The sister, haunted by religious guilt, can't resist the temptation of her brother's growing bulge. She tentatively reaches out, stroking his length through his pants. He responds with a gasp, his hips bucking slightly. Emboldened, she unzips him, freeing his pulsating cock. She licks her lips, her pussy aching with need as she takes him into her mouth, sucking him deeply while he groans and fists her hair.
