Mackenzie Moss has always had a bit of a thing for her stepbrother Alex Legend, and it turns out that she hasn’t been alone in that unfulfilled desire. When Mackenzie and Alex get caught up increasing the stakes of their card games, their desire finally breaks free. They agree that the loser will do whatever the winner wants, but along the way they challenge each other to increasingly intimate bets. Mackenzie flashes her tittles at the window, then gets Alex to whip his dick out to do the same.When Alex returns, he finds Mackenzie naked and ready to take what she’s been wanting. She takes his cock in hand to stroke him off, then leans in for a lusty BJ. Turning around, Mackenzie spreads her ass cheeks so Alex can see the whole show and then moans in delight as he pushes into her from behind. Then she keeps on living out her fantasies by climbing onto Alex’s stiffie and riding him, first in reverse cowgirl and then in cowgirl as she lets his big hips guide her rhythm.Settling in on the couch on her back, Mackenzie watches with satisfied eyes as Alex continues to make himself at home inside her. She pulls her knees back, opening herself up completely. That last little bit of penetration brings Alex right to the brink of cumming. He pulls out at the last time, jizzing on Mackenzie’s belly and twat and leaving Mackenzie thinking that they should play that card game every day.
