My girlfriend's friend gave me a great blowjob and had sex with me instead of her

I've been dating this girl for a while now and things have been going pretty well. She's got a great body and we get along great, but there's just one problem - she's not into as much action as I am. I know, it's a bit shallow, but I'm a guy and I like my sex. So, when her friend came over, I was hoping for a change of pace. And boy, did I get it! This chick is a total sex fiend. She's got big natural tits and a tight ass, and she's not shy about showing them off. She gave me the best blowjob of my life and then rode me like a pro. It was a wild ride and I was in heaven. Turns out, her friend is way hotter than my actual girlfriend. I know, I know, it's wrong, but the sex was just too good to resist.
