Watching my girlfriend cheat on me with my stepdad's huge penis

Witnessing my girlfriend's forbidden rendezvous with my stepdad was a shock. His massive manhood overwhelmed her, and I couldn't resist joining in. The sight of her riding him ignited a primal desire.

I have always been a little bit of a pervert. I love watching my girlfriend get fucked by other guys, especially my stepdad. He has a huge cock that she loves to ride. I decided to surprise her with a visit to my place and as I walked in, I saw her riding my stepdad's monster cock. I was shocked but also turned on. I watched as she bounced up and down on his huge member, her blonde hair flying around as she moaned in pleasure. I could see her tits bouncing with each thrust. Then, I watched as she turned around and let him fuck her from behind, her ass bouncing with each thrust. I could see his cock stretching her pussy as he pounded her hard. Finally, I could not take it any longer and I joined in, fucking her in doggystyle while my stepdad continued to fuck her from behind. It was the hottest thing I had ever seen.
