A curious young virgin finds herself in a compromising position as her boyfriend arranges a threesome with his friend, a doctor. The doctor, experienced in such matters, guides the couple through the teen's first time. He gently inspects her tight, unbroken hymen, causing her to blush and squirm. With the boyfriend's help, he positions her on top, allowing her to set the pace as she loses her virginity, her hymen stretching and popping in a mixture of pleasure and slight discomfort.
