Martin heads out into the street and finds a large post with a rounded top.
He drops his pants and sits on top of it. At first no one expects it to enter his tight asshole. But soon his ass opens up and he has more than a foot of the post up his ass. Riding up and down on it his ass lubes it up and you can see the post dripping with juice.
He cums and rises off the post. But that only holds him for a few moments. He heads down the street and finds a bowling ally. The bowlers are shocked by the fact that he takes a bowling ball and raises it to his ass and it is engulfed by his ass. His abdomen is stretched out and he puts another in his ass. And then another one. It is just like the balls on a chain people stick up their asses but so much larger. As he has 4 stuffed in his abdomen he stands up and his belly is jutting out larger than the biggest beer belly there. Squatting one after another the balls come out and his cock is as hard as a rock. With the last ball he cums hard and is good but just for a short time.
Heading down the street he runs into a biker bar. He finds the biggest man there with arms the size of Bluto and asks for him to stick his arms inside of him. He puts on a show for the bikers and they revel in the abuse they deal out to this man in a suit. And to make it worse a midget biker is picked up and stuffed into his ass feet first. Not allowing him to get off for hours with the midget inside of his ass he becomes more and more horny as the little man wiggles around in his ass his head sticking out his distended butt hole. Having gone into a dizzying coma of lust he wakes the next morning in the middle of the bar with the bikers still molesting him and he begins to have spasms much like giving birth as the midget is expelled from his ass.
This act would be repeated with a larger man in a week.
He can't get enough of things up his ass and he needs it more and more.
