This is the truth bruh lol
My old roommate's girl (now his soon to be ex-wife) did the 'leg thing' with me at least three times. She was a long legged brunette with a cute face and nice boobies. First time it was during the summer on a hot ass night. We were both on the couch and she had her legs stretched out towards and kept brushing them against my leg. Her then boyfriend lived with us too but he wasn't coming home until late afternoon. I wisely went to bed before I did anything dumb. Second time, she straight just rubbed her foot near my balls and it took nearly all restraint not to jump her. I know for a fact she wanted me to.
All in all, I actually liked living with her. She never asked me for anything and we always got along for the most part. After I moved out, I went over to their new place for a bbq and they kept telling me how they could use me as a roommate again but I was like 'naw.' Not going down that road again. Last time me and her had physical contact, I remember the two of us basically 'dry humping' in the living room while her guy was passed out drunk in the bedroom. I had had a few drinks but she was completely sober. And this was after a few years since we had been roommates. I kick myself sometimes when I'm taking a shower because I didn't lay the pipe to her when I had the chance.
You guys seem like mature adults so you may not run until these type of situations. But homeboy said, be prepared. lol
