My friend explores new sexual positions with me

I'm a lucky man, you see. My girlfriend is absolutely stunning and she's always down for some action. She loves to explore new sexual positions and she's always up for a little extra excitement. Recently, I've been working hard to make sure she's satisfied in every way possible. Well, it's not just me, but also my best friend who's been helping me out. He's always around when my girlfriend is feeling a bit frisky. So, the other day, my girlfriend was in the mood for some action and my friend was more than happy to oblige. He's a skinny guy, but he's got some moves that will blow your mind. After a bit of foreplay, my girlfriend was ready for some action and my friend didn't disappoint. He took her from behind and she moaned in pleasure as he explored every inch of her. It was a sight to behold and I couldn't help but be turned on by it all.
