Thanksgiving is supposed to be a time of gratitude, but Rosalyn Sphinx decides to play a prank on her stepbrother, Juan Loco. She clears her plate and asks for more food. When Rosalyn's mom, Jessica Ryan, comments on how good her daughter's appetite is, Rosalyn announces she's eating for two and the baby is from someone at this table. Jessica immediately turns on her husband, Rusty Nails. Rosalyn stops Jessica from beating on Rusty with a baguette by saying it's not him, which leaves only Juan. Juan is as surprised as his parents, but he takes the yelling and baguette attack that ensues.

Later, Rosalyn comes to Juan's room to offer a halfhearted apology. Juan claims he may as well blow a load in his stepsis since their parents think it's true. Rosalyn claims he can have it any time he wants it, but only if he gives it to her right now. Juan hesitates, but the promise of that pussy peeking out from Rosalyn's miniskirt is too much temptation to resist. He lets his stepsis pop his boner out, then lay back and wait for Juan to do it. Rosalyn pops her titties out to play with, and that's when Juan guides himself into her greedy snatch. Soon he's pumping away as Rosalyn eggs him on with her moans.

Getting Juan on his back, Rosalyn fills her lying mouth with her cock as she sucks him off. Then she climbs onto Juan's lap and mounts him in reverse cowgirl to enjoy a wild ride. Turning around, Rosalyn finally peels off the last of her clothes before delivering a cowgirl stiffie ride that gives Juan a full frontal view of her bouncing boobies and her trimmed twat. They do it next in doggy with Rosalyn thrusting backwards to meet each of Juan's thrusts. She begs Juan to cum inside her and he does as she asks, glutting her with a big creampie. That's when Rosalyn lets Juan know she's not actually pregnant, but she probably is now!
