Sloppy Seconds with my FWB, first time

When I was 22(m) I had no gf, but a fwb. She (23/f) wasn't great looking, but we were friends and it just came naturally. I was hosting a party one night (everyone over 19) and lots of people were passing through. I had invited my new friend (19/m) over and he was being introduced to our group, shy.

Well the night was going great and drinks were flowing. I used to have a few too many when I was really having fun, and I remember thinking "I'm going to rail her so hard later". That's about when I lost track of the time line of the night.

I played some games with the party guests and soon was wondering where my FWB and my new friend were. They weren't anywhere inside. I look out back to see her with no pants lying in the grass and my new friend banging away at her in plain sight in the backyard. Shocked,, but without them seeing me or stopping them, I stumbled inside to get another drink.

A few hours later I find myself in my room with my FWB. I don't remember when we got there. I'm going down on her and we're both fully naked when I remember that she had just been railed by my new friend in the backyard in the grass. Oh well, it was too late to stop now. I flipped her over and fingered her back door while I called her a dirty slut and gave her my meaty cock. She could never resist it. I used her for hours until we were both spent and covered in bodily fluids.

To this day, I never told her that I caught her before we got into bed. Since no feelings were attached, it has become a very hot memory for me.
