A guy enjoys my voluptuous girlfriend in various positions

I've always been a big fan of my girlfriend's curves. She's got a set of tits that would make even the most jaded man weak in the knees, and a ass that's so round and plump, it's practically begging to be spanked. But lately, I've been feeling like I'm not getting enough action from her. Sure, we have sex every night, but it's always the same old positions. So, I decided to bring in my buddy to spice things up. He's not exactly my favorite person, but he's got a pretty decent body and he's not afraid to use it. We started off with my girlfriend giving him a blowjob, which she does better than anyone I've ever seen. Then we moved on to doggystyle, with my girlfriend's ass bouncing up and down as she rode his big, fat cock. It was a sight to behold, and I couldn't help but get turned on by it all. We tried a few other positions, including a couple that I'd never even heard of before, but they all ended with us all three moaning and groaning in ecstasy.
