Two curious teens, barely legal, find themselves alone and horny in the confines of their home. The 18-year-old sister, a raven-haired vixen, can't resist the allure of her brother's burgeoning manhood. Their initial innocence gives way to exploration as she tentatively wraps her small hand around his hardening cock. Her brother, 19 and equally inexperienced, gasps as she strokes him, his body reacting to her touch. They stumble through their first sexual encounter, a mix of clumsy passion and innocent desire, their young bodies quivering with newfound sensations.
