My girlfriend and I having sex in my stepdad's house

Me and my girlfriend have been dating for a while now and we've been trying to spice things up in the bedroom. I've always been into some wild stuff, but she's always been a bit on the vanilla side. But when we found ourselves in my stepdad's house, something clicked. We decided to try out some kinky stuff right there on his couch. She started off by giving me a blowjob, her lips wrapped around my big cock. Then she bent over and I took her from behind, pounding her hard. The thought of my dad potentially walking in made it even more exciting. We continued our wild romp, trying out different positions until we both reached our climax. It was the hottest sex we've ever had and we can't wait to do it again.
