A threesome with my girlfriend and her stepdad in the living room

The scene opens with a stunning brunette, her gorgeous girlfriend, and her stepdad all sitting on the couch in the living room. The girls are dressed in sexy lingerie, while the stepdad is in a button-down shirt and khakis. The girls start flirting with each other, and soon the stepdaddy joins in on the fun. He starts kissing the girls and touching them in all the right places, and the girls are more than happy to reciprocate. They take turns sucking on his hard cock, and then he bends one of the girls over the sofa and starts fucking her from behind. The other girl takes her turn being doggy style, and then they both take turns riding him on the cushions. The girls share his cock, taking turns being on top and in the middle, and then the stepdaughter finishes him off by taking his load in her mouth and swapping it with her friend.
