The school bus was packed tight with people, and I was next to a married woman with huge breasts, and I was getting really horny. Every time the bus shook, our bodies pressed together, and when my boner touched her, it got even harder. The wife felt my erection hitting her butt and crotch, and her sexual desire ignited, so she secretly squeezed it. I couldn't hold back anymore, and despite other passengers being on the bus, I followed the wife's lead and inserted myself into her.
