Them first two slaps where kinda cute like he had never done it before and was trying it out but he didn’t want to actually hurt her, a feeling I can sympathise with as I’m a big guy I’m talking body mass I’m built on the scale of if you took a fantasy dwarf and sized it up to 6ft so I can quite easily brake people if I’m not careful, I had one girlfriend that wanted me to choke her while we fucked and I was totally against it I mean 1 I didn’t want to hurt the girl I love but also I didn’t want to get into trouble if anything went wrong but eventually she convinced me and while she apparently loved it based on how hard she was clamping down on me but it made me feel ill like physically sick and there was no way I was willing to do it again which sucks for her but she saw how it made me feel and for the next year we were together she didn’t as again, we did lots of other stuff she wanted so I’m sure she wasn’t to bothered about it.
