Unexpected Sloppy Second

It was a party and I hooked up with a girl on that night.
Long story short she was very flirty and we went outside. First we talked then she bend over just against the wall.
Well I pulled my cock out, put it inside her and oh boy was she wet.
She was soo wet that I didn't feel much.
After the smell of cum was coming to my nose and my crotch was wet I realized what I was fucking right now.
I stopped looked at it and yeah. She took a big creampie just some time ago.
I finished into her and we left.

I saw her later talking to another guy.
