I won a bet and fucked her hard in the ass [MF]

I met this girl in the gym I work out. Long story short we became fuck buddies. She is a small girl, 19 yo, blonde short hair (almost male haircut), not very pretty face…but…she has a piercing on her nose that makes her really fuckable, she has some kind of weird charm, skinny and short with small boobs, but… a very well formed heart shaped tiny little cute booty which since I first layed my eyes on it I knew I had to put my dick inside it some day.

So we had casual sex once every few days, no anal. Once during pillowtalk after sex I asked her if she tried anal she said never, and doesn’t sound appealing to try it.

Once we had a bet about something and the deal was the winner chooses what he gets. I won and when she asked me what do I want I said I will tell you when I figure it out. (I knew already lol)
