In the dim light of their childhood home, a brother and sister, bound by blood and forbidden desire, succumb to their secret fantasies. She, a virgin, tentatively strokes her clit, while he, hard and throbbing, watches from his doorway. Their eyes meet, and the dam breaks. He joins her on the bed, their bodies pressing together. She tentatively touches his cock, her inexperience making her clumsy but eager. He guides her, teaching her to stroke and suck. Their moans fill the room as they push each other closer to the edge, their incestuous lust consuming them until a sudden noise from downstairs jolts them back to reality.
