Now Jeremy would have sex with all sorts of men from time to time and an occasional woman but when he got so drunk and went home with Nathan Jeff was just not having it.
Nathan was a bottom and enjoyed getting fucked but when Jeff was human he wouldn't even give Jeff the time of day. Nathan was a buff muscled jock and although Jeff wasn't the most well built he wasn't bad but that just wouldn't do with Nathan.
It was when Jeremy and Nathan went home and Jeremy dropped his pants that Jeff realized that it was Nathan. That immediately angered Jeff but Jeremy's mind was too clouded by the alcohol to understand what Jeff was saying and almost immediately Jeremy and Nathan got in bed.
Nathan was face down giving Jeremy full access to Nathan's ass and as he thrust deep with no preparation Nathan could feel the huge cock impaling him. Nathan loved a big cock and wasn't worried about the size.
Jeremy thrust and thrust and when Jeff could feel he was ready to cum Jeff increased the amount of cum and the size of Jeremy's balls to the size of two bean bag chairs.
Jeremy was too out of it to realize how much cum he was filling Nathan with but when he woke the next morning he was laying next to a mountain of a man. Nathan couldn't move from the bed. He was pinned by the 100 or so gallons of cum Jeremy pumped into him.
Jeremy began to scream at Jeff telling him that he could have killed Nathan.
That wasn't the point but now that his belly is stretched out he wont ever have that body again. And surgery wont help much leaving him with scars if he tries to go back to his old body. If he's smart he will find himself a good man that likes fatboys and keep that belly filled with food and cum.
It took a week for that cum to be absorbed into Nathan and Jeremy kept that belly filled as the cum was absorbed. Nathan was enjoying the new attention to the bloated belly but this was not what Jeremy was interested in but he felt some responsibility for Nathan's state.
As soon as Nathan was able to waddle out Jeremy sent him on his way and would see Nathan from time to time. His new look was astonishing.
But Jeff now knew what he could do and enjoyed filling people with Jeremy's cum.
