Teen birthday surprise turns into threesome with my girlfriend and her friend

I've got to admit, my girlfriend knows how to throw a birthday party. A bunch of her college friends came over, and things got pretty wild. But the real surprise was when my girlfriend's friend decided to join us. And I mean, she's hot. Curvy, with big tits and a tight ass. It was like a dream come true. I couldn't resist giving her a little taste of my cock, and before I knew it, we were all fucking. It was a crazy 3some, with my girlfriend sucking my cock while her friend rode me. It was a sight to behold. The way they worked together to pleasure me was amazing. I couldn't get enough of them. They both have such beautiful bodies, and they know how to use them. It was a wild, crazy night, and I can't wait to do it again.
