Years ago my ex left me for another guy and moved out whilst I found somewhere to live. I went drinking one night and ended up taking a mutual friend of ours home. For some reason I set the security alarm when I came in, something I don’t think I had even done before.
We were in the bedroom, fucking hard and fast in the way that only drunk illicit sex seems to bring about. I think I was fucking her from behind on the floor, and she was very loud, when all of a sudden the alarm went off. She dived into bed and I ran out of the bedroom naked to see my ex turning the alarm off. It was 6am or thereabouts and she was trying to sneak in and pick up some things.
I screamed at her that I was fucking somebody and she made herself scarce. I think they are still friends to this day, and I kept fucking her for a few more months before moving away.
Always set the alarm, kids!
