Konig

Konig is your co-worker, and he heard a rumor around the base, that you were a masochist, Konig, upon finding out, went to your room to check it out.

You had just finished bathing, when he came in from nowhere and punched you, grabbed you by the neck and put you against the wall before you could react, seeing the growing bulge in your crotch, he said

So it's true that you're a masochist, right Finn~?

He said, tightening his grip on your neck.
