It was more than a year of cumming into their relationship and Ben had been watching Matt make the changes
He liked Matt but there was just something missing and just as Matt made the change to their almost daily transformation Ben sat down in the chair and started making changes to himself.
What are you doing Matt asked.
Oh I just thought we might kink this one up a bit. I have been thinking about this for awhile.
As Ben made the changes Matt, the condom, couldn't tell what was being changed.
Just as Ben hit submit Ben's balls became the size of a bean bag chair each and his cock grew to two and a half feet long.
What the hell. Matt screamed at Ben just as Ben tore him open and started stretching him over his base ball bat of a cock.
Matt hadn't thought about it but he was really enjoying this. More than he had ever enjoyed his sex with Ben.
When Ben had started stroking it was counting down from 5 minutes and less than a minute when Ben's eyes rolled back in his head and he started to cum into Matt.
The count down continued and Matt was still on Ben when he started to change back. His arms and legs poked out his head popped off the top and he really felt that bat up his back end and he was filled with gallons of cum and it was still shooting into his guts. He had a beer belly that lifted him off the bed. It must have been easily 80 inches around.
I am so sorry Ben said to Matt. I thought I would be done long before you changed back and I could wash you out. It looks like you are going to have to metabolize all that cum inside of you.
Matt stood up trying to balance that belly full of cum and rubbing it. Don't worry I am liking this. He found his belly overly sensitive as he stroked it and saw all the stretch marks around.
Now Matt couldn't get rid of the cum but he did sit down at the computer and gave himself a furry belly. I always wanted to be a bear and now I look the part.
It took over a month before Matt was ready to take Ben's now permanently enlarged cock up his stretched out condom transformation but as he sat down to make the transformation he also pulled up Ben's and made his balls bigger than they were the last time. He gave him an overly active sex drive and the same 15 minute transformation time so that he would feel that baseball bat up his ass as he changed back to human and felt his belly filled with Ben's baby makers.
This was going to be fun.
