Knowing that something interesting is about to happen, Andi excuses herself to go change into some sexy little jammies. Kyle takes the opportunity to put his dick in the advent calendar he's just created. He gets Andi to open the day he has fucked, then waits for her reaction. Although Andi is shocked and a little bit upset at first, she has to give her stepbro ten points for creativity. Kyle insists on ten licks instead. Andi thinks about it, then decides that's fair. She counts out ten licks of the tip, but then finds that that's not enough. Removing the calendar, Andi takes a big mouthful to suck in a deep throat BJ. Even that isn't enough for this cum hungry coed, so she leads them to the bedroom where she can really suck Kyle down and then have some fun.
Laying on the bed with his stepsister's lips wrapped around his hardon is great, but Kyle is even more excited when Andi straddles his hips and sinks down to ride him. Her hands are all over her boobs as she bounces on Kyle's dick. Falling to her side, Andi lets Kyle do some of the work as he spoons her to fuck her from behind. When Andi rolls onto her knees, Kyle gets behind her and delivers the rough doggy style pounding that his stepsis needs. He finishes her off on her back, which leaves Andi responsible for Kyle's pleasure. She's cool to get back on her knees and open wide as she rubs one out for him. Kyle's cum shot hits his stepsister's open mouth and drizzles down to her breasts, giving her a sticky Christmas mess to enjoy.
