So my girlfriend Brie and her roommate Kristin (and here’s a [drawing](http://i.imgur.com/O8r8a3J.jpg) for reference! Kristin is in blue, Brie is in black) were really into sex positivity and had some flexible sexual borders, which led to [my GF’s roommate masturbating while she watched us have sex](https://www.reddit.com/r/gonewildstories/comments/bc38cs/roommate_f_wanted_to_watch_us_mf/) which escalated into [me and Kristin having sex](https://www.reddit.com/r/gonewildstories/comments/bdq0e3/gfs_roommate_didnt_just_want_to_watch_anymore_mff/), completely with the blessing of my GF. Everyone all caught up? Good.
The dam had burst. The next month after Kristin and I had sex, I never quite knew what to expect walking into their apartment. There was a lot of nudity. Kristin hadn’t had a lot of playfulness in her sexual experiences, and Brie and I could tell she was really enjoying it. She particularly seemed to enjoy pulling her shirt up and showing me her boobs, shaking her hips, and promptly walking away. Brie said that she could tell that Kristin enjoyed being able to flirt (and flaunt) without any expectations on her.
