POV surprise as busty girlfriend rides my cock and cums inside her

I’m an amateur with a big cock and a girlfriend who loves to ride me. She’s a beautiful brunette with big, natural tits and a tight ass. She’s also a college student, but she doesn’t look like one. She’s always down to have sex and she’s not shy about it. One day, we were in my bedroom when she surprised me by jumping on my cock. I was caught off guard, but I enjoyed it. She rode me like a cowgirl, bouncing up and down on my hard shaft. It was a sight to behold. She took me deep inside her, moaning with pleasure as she did so. When she finally came, she let me fill her with my hot load. It was a creampie that made me feel amazing. It’s not every day that my girlfriend surprises me like this, but I hope it happens again.
