How did I know your mother

Two mates, Max and Ricky, like to tell each other their sexual exploits that they regularly perform with cougars: blonde, brunette, small or big breasts, nothing resists them, and sometimes they do the race to find out who fucked more than the other ... But the problem with this situation is that even their own mothers will not escape their endless appetites: everyone will tell that he has fucked the other, without even knowing it!
