My step-son turned 18 and it's time for mommy to show him that size doesn't matter. I make him to show me his small penis and I start sucking him. After that I squat over him and all I want more is to piss on this little cock. I can't resist anymore so I piss a huge amount of pee on him. I rub him against my pussy, I slap him against my pussy, and finally I make him cum on my pussy. I also orgasm and squirt at the same time.
