If cosmetic treatment is performed on a delicate part, you wouldn't want it to harden. Even the therapist wants to poke into the front of a returning being. However, it is forbidden to guide you to insert from yourself as a rule... So, I would tempt you to insert 1 cm through your underwear. "Well, can I just put it in?" "Just the tip will do..." Just let the man beg to be inserted like a lucky seductive flower... Isn't it vivid?
