One of the girls I had after D and I split was fairly small blond that had a few kinks of her own. Once I was fucking her from behind and she said hit me. So I slapped her ass. Not like that use your fist. So I punched her a little. Harder. So I punched her right ass cheek as hard as i could. Instant orgasm.
Now I was used to slapping ass or tits but full punches was not anything I'd done before and haven't since her.
Another time she was riding me and I was squeezing her little tits. she took them off and put them on her throat saying choke me. So I start off gently , she shakes her head no Harder. So I squeezed harder. The redder her face got the faster her hips moved. I let go when she started cumming. She collapsed on me with a smile.
Another time I took her to the cemetery so she could visit a grave. After we got back in the car she leaned over and took my cock out and gave me a BJ, She even swallowed all my cum, something she didn't usually do.
After we split I missed having someone to fuck, but I'm still not sure how I feel about the punching and choking to get her off.
