A mature doctor watches a virgin nympho's first time penetration

The scene opens with a mature doctor, who seems to be in charge of the situation, watching a young nympho getting ready for her first time penetration. The nympho is a beautiful 18-year-old, with a perfect body and a shy smile. The doctor sits on a chair, watching the nympho undress and get ready for the doctor's help. The nympio is clearly nervous, but the doctor seems to be enjoying the show. The doctor starts to poke the nymphos with his fingers, making her moan with pleasure. The doctor then takes out his cock, and the nympha eagerly takes it in her mouth. The doctor's cock is huge, and the young nympha can't handle it. The doctor takes control, and the two engage in a wild three-way with the third person, a young man, who is also watching the show.
