My Roommate is a Slut

Katie is a slut; that's not a judgement, just an objective observation. If you asked her if she was she'd admit it, after she pulled whomever's genitals were in her mouth out first of course. I wasn't exactly aware of the depth of her slutiness when we first met months ago and agreed to move in together, but it wasn't long before I started getting a good idea.

She was bringing home different people every night it seemed like. She occasionally got into relationships but they didn't seem to last long since she didn't seem to try very hard to hide the cheating. The only thing that seemed to give her pause was when Stephanie came over she'd be on her best behavior, at least while she was in the room. As soon as she was out of eyesight she cranked the teasing up. It started out just flashing and dirty talk, but lately she's been cranking it up with touches and I'm not sure if I'm going to be able to keep resisting her.
