When a beauty salon treats a sensitive area, you may end up with an erection involuntarily. Even a therapist can't help but want to fuck her when she sees something so warped. However, according to the rules, it's taboo to guide her into insertion...so she seduces her by letting her insert 1cm of her body through her panties. Eh, can I put it in? Just the tip is fine... Just to the end.
