SCOP-613 Sneak out when using a subterranean call that can be inserted

It's true that there's a kind of underground call-in story that when it's fun to play with a very popular call girl's care, and it's like a top-up in the name of a special service, but I don't know if it's pretty cool to get a call girl to come in, and then, in the back, sneak out the call girl's S.I. corner, because even if it's undetected, let's just get it out.
