A plain girl (dental assistant/medical secretary/beautician) with big breasts but no self-confidence tries her first forced seduction on a bus full of boys' high school students! Even with the awkward contact, the sensitive boy gets a full erection immediately. The plain girl becomes aroused at the sight of such a young cock! She jerks him off like a different person, making him cum over and over again! She can't suppress her desire for sex and ends up inserting the cock herself...
