Sheri let out a surprised ‘UHHH’ that was quickly muffled by his cock sliding into her mouth, the head bumping the back of her throat. Sheri’s e...es opened wide as her sounds became a moan of enjoyment. She started sucking him greedily, making sure to get Tom’s dick as wet as possible, to make it easier to take it into her throat. Both of his hands were in Sheri’s hair now, as he began fucking her face. Tom let out a small moan, which only served to fuel Sheri’s passionate cocksucking. As she. .. can't believe it! Too much! Too fucking much, baby! Fuck me Nigger! Fuck me harder! Oooooh, that's it! Fuck my ass with your big black prick! Fuck my Asssssssssss! Ooooo shit, you're killing meeeeeeeeeeeeeeeeeee! Cum in my ass!

Shoulder-length, silky brown hair, and dark brown eyes to match. I really enjoyed. I mean I lost to someone who had sex a couple times before. So she was a little experienced I guess. Why you wanna know what sex is like when you have it?” Jim asked. “Well yes I guess I want at least a little insight to it. I mean I just don't wanna have sex with a guy and have him leave because I wasn't good,” I replied.“Oh sis, your pretty sexy and I'll admit it, a little hot. I suppose that's a little sick to think of sister like that, but that's the way I feel about you,” Jim explained..
