This Family Got More Than Friendly
Back in 2016, Robby D. and Paul Woodcrest directed "Family Friendly" for Digital Sin/New Sensations. The dirty and pretty damn hot movie was up for Best Taboo Relations Movie at the AVN Awards that happened after its release. This is a pretty great cast and the sex in every scene is just fucking smoking, especially if this kink is your bag. The acting is really, really strong which is really important when it comes to this fetish.
AVN Hall of Famer Tommy Gunn ends up walking in on his super hot stepdaughter Gina Valentina who is trying on his clothes. The scene is stupidly hot and her body is off the charts beautiful in this scene. Kristen Scott offers herself to her stepdad/AVN Hall of Famer Toni Ribas and she agrees to keep everything a secret. Their pairing is really, really hardcore and one of her hottest scenes. Bobbi Dylan has an ongoing sexual relationship with stepbrother Xander Corvus that she hides from her friends in this too and wow, Corvus enjoyed fucking her in this.
