Grandpa fucks two granddaughters hard for violating discipline at the university

The grandparents agreed to shelter their granddaughters at home for a couple of months, but the old people did not even imagine that the blond young women were a real chest of problems. Today they are even called to the dean for an educational conversation, during which the grandfather decides that the heifers need to be brought up so that they do not grow up to be some stupid whores. Alone with a blonde granddaughter and a blonde in the bedroom, the old man orders them to undress, and then get on all fours and suck his protruding penis. Having coped with a double blowjob, the granddaughters take turns substituting pussy for fucking, simultaneously doing cunnilingus to each other
