A taboo trio gathers for a clinical exploration of virgin territory. The doctor, a sultry seductress, has the girl strip and lie back, her legs spread wide. She runs her gloved fingers along the girl's smooth, wet lips, then pushes them inside, stretching her tight hole. The boyfriend watches, jerking off as the doctor works the girl's clit, making her moan. She brings him closer, lubing his cock, and helps him push past the girl's hymen, filling her with his hard dick as she holds her legs open, revealing every intimate detail.
