Mr. Marko is off on another business trip and it’s time to say goodbye to his nephew. Since Mr. Marko found him and introduced him to his father, Dr. Wolf, the three of them have had a lot of fun together.

All three of them are loving it, but before Serg can breed his Uncle, Mr. Marko and Serg’s dad want to remind the boy of his place in the family hierarchy. Dr. Wolf lays back on the sofa and tells Serg to climb on. Serg starts riding his father’s dick like can’t get a load in his hole fast enough.
Once his boy opened up and lubed with cum, Dr. Wolf orders his boy to take his Uncle’s load as well. Serg is more than happy to obey. With Mr. Marko begging through clenched teeth, “Don’t stop! Don’t stop!” Serg rides his uncle to an incredible climax…
