Innocent stepsiblings Michelle and her brother find themselves alone, their attraction impossible to ignore. Michelle, a virgin, has never seen a cock before, and her brother's massive erection excites her, despite her initial shock. They tentatively explore each other's bodies, Michelle timidly touching her brother's thick shaft while he gently caresses her small, firm tits. Their first time is intense, Michelle feeling a mix of pain and pleasure as her brother's virgin cock stretches her tight pussy. They kiss passionately, their bodies entwined, as they cross the forbidden line together.
