Fuck your sister by surprise because the bitch wants to win a bet

The stakes lose this little fox, who is capable of doing whatever it takes to be right in a competition with his brother. Uncle poses the challenge of placing a dildo in the butt hole to see first if he holds it and then check if he can tell when he changes the dildo to his dick. The bastard assfucks his sister and her slut, although he realizes he's already started fucking her, let him continue because he likes to break her ass well with his ass.
