My stepdad watches me pleasure my new girlfriend orally

I've been on a mission to find some new action to spice things up with my girlfriend and I think I've finally found it. My friend's dad has always been a bit of a wild card, with some strange fetish that nobody really understands. But, when he caught me pleasuring my new girlfriend orally, he couldn't help but come over and watch. It was kind of creepy at first, but then I started to enjoy the attention. After a few minutes of intense oral pleasure, we moved on to more physical activities. First, we took things slow with some missionary action, but then my girlfriend wanted to take control. She climbed on top and rode me like there's no tomorrow. But that still wasn't enough for her. She wanted to try out doggy style, and then get fucked hard from behind. By the end of it, both of us were satisfied and my stepdad got to witness a hardcore session.
