If you get a massage in a sensitive area at a beauty salon, you'll unwillingly get an erection. Even the therapist will want to have sex with you when he sees your rock hard cock. But according to the rules, it's taboo to induce insertion yourself... so she tempts you by pushing it in 1cm through your panties. "Oh, can I put it in?" "Just the tip is fine..." She makes the man beg for insertion and then inserts it like a lucky pervert... he was so eager to cum, wasn't he?
