Lexi Luna tried to take her stepdaughter Scarlett Hampton and her adopted son Rion King on a canoe trip, but everything that could go wrong did. Even now that they're back home, the family won't stop bickering. Rion takes it too far by telling Lexi that the problem is she's probably bitchy because she hasn't been fucked in way too long. When Lexi tells Rion that that's none of his business and calls him a little man, Rion takes immediate offense. There's nothing little about the dick he so proudly whips out of his swim trunks.Lexi is still spoiling for a fight, so asks Rion what he's going to do with that and then pulls her bikini bottom down so her pussy is exposed to taunt him. Scarlett follows her stepmom's cue and pulls her own bikini bottom down. The girls even flaunt their titties out to keep on teasing Rion with the unattainable. Scarlett keeps on toeing the line when she throws herself onto the couch and really puts her twat on display. Standing behind Rion and heckling him, Lexi shoves him forward. He trips on the way down and finds his dick buried inside Scarlett's fuck hole. Scarlett and Rion are both shocked, but Lexi, who is still behind Rion, just starts pushing his hips so he's full on fucking Scarlett. Scarlett can't deny that she likes the way that feels, and now that Rion is buried balls deep inside his adopted sis he can't deny that it's so wrong it feels right.Now that Rion is on board to give them both some, Lexi gets on her knees on the couch so he can dick her down from behind. She doesn't want Scarlett to feel left out, so she pulls her stepdaughter forward and goes to town on that pussy. The girls sit Rion down and go to work together to reward him for being open to new experiences by delivering a double BJ. Then Lexi climbs on top for a reverse cowgirl ride that gets those big boobies jiggling as Scarlett plays with them. When it's her turn to play, Scarlett gets on her hands and knees so she can enjoy Rion banging her while Lexi jiggles and cups his balls to encourage him to dive as deep as possible. The position leaves Rion ready to blow his load and Lexi wants him to do it inside Scarlett's pussy. Rion is an obedient stepson who does as mommy tells him to, glutting Scarlett with a creampie that Lexi is happy to help lap up, even as Scarlett is shocked that her adopted brother came in her.
