His prostitute cousin does it for free with him
We have always known that when you are a professional at something, your first experiments have to be done with people in the family. No matter what it is, these will always be the guinea pigs for you to learn how to do it right. Then since you do it well, then you have to continue offering the service. And the same for this kid, his cousin is a prostitute and now she does it for free with him. She can’t charge him for giving him cock sucks, much less for letting him penetrate her pussy. Since they are from the same family and that is what families do all over the world.
