I used to have this fuck buddy that was into rough sex. She and I would get high a lot together and go out drinking then one night she calls me up at about 3 in the moring to come over and smoke with her. We are hitting this bowl and she traced my lips with her finger and goes "I bet you know when to slap it and when to stroke it" and then turned around and stuck her ass in my face. So I started slapping her ass and I thought I was slapping it pretty hard and she was purring and whsipering "harder, harder, harder" so I slapped her harder and harder. She was wearing a micro-mini skirt and panty hose and those were just getting in the way so I ripped them off to get to bare skin (lucky she wasn't mad I ruined her clothes). While I was banging her I was slapping her face, her ass, her tits, her pussy, clubbing her, biting her nipples almost off, had my hand wrapped in and around her 3 feet of hair pulling her around by it, throwing her face first into the walls, throwing her from couch to couch and every other piece of furniture, grabbing her by the back of the elbows so she couldn't use her hands to protect herself when I threw her into things, choking her, just really really rough. She went to sleep for a couple of hours and I stayed up because I saw that her face and ass and tits were all red with even handprints and I thought she was going to turn blue and bruise and maybe call the police. In those couple of hours she was like Wolverine and healed without a mark and it continued again till late that afternoon.

She had a boyfriend but she told me he didn't know she liked it rough and she didn't want him to know because she wasn't like that all the time and he might want it like that everytime. So whenever she wanted it rough she called me up. When you slap the ass cup your hand instead of using a flat hand!
