Sexy ass Staci and Hillary fondle each other while Mark watches. They kiss and play with each other's asses and then one of them polishes his dome while the other sucks his nutsack. They take turns sucking him in varied positions and then it gets even hotter! Both lick his shaft and pump his cock repeatedly. He switches suck and fuck partners and these girls vary between fucking around with his member and playing with each other. They keep going like this until he is ready to bust his nut. When he does, both are on hand to catch every drop into their mouths. And did I mention that they are twins? Wow, that's hot!
