I was reading a pornographic book at a bookstore and got an erection... I looked around thinking this was bad, and my eyes met with a busty female clerk who was very tempting! I was trying to get away with it, but the clerk pressed her big breasts against me from behind and touched my nipples and crotch! She gave me a handjob and rubbed my erect penis against her crotch! It felt so good I couldn't move, and she used me as her toy!
