Shari's hips rolled to and fro as the tension in her pussy grew with every movement, while the young stud was now totally in her thrall as he had given up any pretense of trying to escape his position!!! "You've got a big cock," Shari moaned softly, "I'll bet your girlfriend just loves it when you give it to her in the ass!!!" "Oh, my god," he gasped, "you're such a slut, I've never met anyone quite like you before, you're a true fucking cock hound!!!" Her pussy was now way past the point of no return, and as she bounced up and down on him, she moaned loudly, "I'm fucking cumming you fucking stud man, ohhhhhhhhhh, yes, give me your fucking meat, big boy!!!" This woman who was riding him for all he was worth had the nastiest mouth of any woman he had ever heard, and unbelievably, it was turning him into a fucking machine, as he pounded away on her hot fat cunt, and just as he was about to join her in orgasm city, a sound from outside the stall door made him freeze in fear when a feminine voice asked, "Is that you in there, Shari, what in the heck's taking you so long, anyway!?!" "It's just my friend, Mona," Shari whispered to Seth, "I'm gona let her in so she can watch, okay!?!" Seth was about to say no, but again she was too fast for him, and a five seconds later Mona was standing in the corner of the stall with her skirt up and her finger in her pussy!!!
