I was dating this guy and he was into kinky sex, we would experiment and he bought me these nice boots and would ask for things in bed such as jerking him with my boot heel, boot fuxxing and light ballbusting.

It was hot and I liked how he would submit to my voice, I would talk in a soft seductive voice saying things like, that's nice, look at me, naughty naughty.

He asked me to use specific words, that's nice was one that got him worked up and naughty naughty.

I thought I was doing him correctly but eventually he started looking at other women and I noticed but didn't observe because some guys just do that and over time he seemed to get more and more close to one of my friends and I grew suspicious and he started coming back late or would be unresponsive on FB while he was home so 
One night I talked to my boss and asked if I could leave early he said yes so I drove back and didn't go fully into the driveway and I walked quietly up to the door and I heard him and my friend.

I went inside and the noise, it was obvious, I left and came back later, I didn't want him to know so I purposely asked him for some time in the bedroom and the horny fucker had enough energy so we do the usual thing he's on top then me then I put my boots on and get him off talking the way he wants and I thought of a spiteful way to get back I'll use the turn ons he asks for but with a twist so I wait and leave work early again a week later and he's with her again and I walked up the stairs quietly and he's got her bent over on the bed and he's so busy banging her from behind he doesn't notice me out floor has carpet so it would be perfect I put my boots on and walk up behind him and it seemed like he was going to cum and he's moaning and I said in the most sluttiest voice....nice balls and he stops and I kick him from behind he closes his legs and makes this high pitch noise and hes holding his balls and I didn't care I kicked again and my now ex friend is on the bed and tries to leave I grab her by the hair and throw her down and she grabs me and we both fall I fell on top and I felt my chance I kneed her between the legs and got up and kicked her in the stomach, he's on the bed holding his balls looking shocked.

I was so angry
