I don't think the girl was doing privates with the guy. In the video where she gets in the tub, once she gets in, she says "I'm ready for my Master," so I figure slave/master relationship where he used her and she got to stay at his place.

I think the conversation probably starts with her dropping some sort of terminology used in the relationship while at her parents place, and mom asking prying questions (cause she always knew something wasn't right about the guy). Being a good sub, and mom her first master, she answered everything she was asked. Then an exit strategy was concocted, because there was furniture to move. This pic was in the collection also:



I'd figure the left behind Dom was a lil bitter, and that is why the pics went up on 4chan, and then to where I found them.
