I didn't believe my roommate when she told me she loved rough sex because she seemed so tiny and frail. So, she lifted up her shirt and showed me the hand-shaped bruises on her breasts! I couldn't believe she loved being mistreated and then she did something crazy. She called her boyfriend to come over and have a threesome with us. I had my first lesbian sex and I was really, really rough with Regina. I couldn't believe how much she could take and how much she and I would both love it.
