The only type of sex Bob ever had was the type he was about to have again. He'd been jerking off for several years, since a friend of his had told him about it. But a day hadn't gone by since that first orgasm that he hadn't wished with all his might that he could stick his hard cock into the mysterious cavern between a girl's legs.

Bob strained his earn and began moving his fist up and down on his joint, dragging the loose skin up over the fat head, then down until his cock was taut and his hand was pressing on his big balls. He tried to imagine what it would be like to be in the place of that lucky guy in his mother's bed. He could only approximate the sensation since he had never experienced more of a woman's body than a few quick feels of young tits.

The idea that some guy was lying naked with his mother, and feeling her big tits on his bare chest while free to explore every nook and army of her gorgeous body was absolutely incredible to him. The reality of the situation seemed too good to be true.

Bob heard his mother's moaning rise to a pinnacle of lust, and he followed the sound with his pumping fist. When she was expressing the frenzy of a coming, cunt-lapped sex fiend by her wild wails, Bob was sharing her pleasure. His cock was bucking and burning, and soon a fountain of gism was leaping from the tip of it.

It was fascinating jerking off to the sounds of his mother's lust, but the climax was spoiled by the jealousy he felt toward the guy who was getting the real thing. As he lay in bed in horny madness, he plotted ways to get what he longed for so desperately. If his mother fell asleep before her boy friend left, he could wait for the guy to leave, then crawl into his mother's bed and pretend to be the guy and fuck her.
