His cock was at his knees soft and his balls were so big it was hard to move around without hitting them so he had to do a sort of waddle that made the girl laugh.
As he went to grab the girl she screamed and soon he felt his balls growing larger. The weight in them started to stretch the skin around his balls so that they hung lower than the end of his cock.
No please I don't want this please let me go back to normal. He began to cry.
His balls were the size of soccer balls making his cock look appropriately size but they should have been on a body twice the height as this man.
If you can go 24 hours without cumming I will think about it.
But as he tried to waddle his way out of the park trying to hide himself he was grabbed by the arm and pulled into the bushes.
There was the biggest burliest man he had ever seen. He was scared. He couldn't move fast and even if he had a normal sized set of genitals he would probably have been easily pounded by this man.
What do you want he pleaded with him.
YOU!!!!!!!!!!!!!
What do you mean by that?
He bear pushed him down on the grass and began to stroke that huge cock of his.
NO NO NO please don't make me cum. I'll never be normal again if you do!
I heard.
As he stroked the man's cock it got thicker and thicker and longer and longer. There was a lot of blood flowing to the cock and he was truly enjoying the stimulation and without knowing it he was soon impaling a young boy. Not the bear but a boy of about 18 years old and with a slight build.
The big bear was holding him around his chest helping him rise and fall on the man's cock. The pure agony in the boy's face was apparent but he only let out a whimper here and there. He was well trained by the bear.
As he grew close to orgasm the boy finally was sitting on his crotch. He could feel the cock lodged in him as it spewed his sperm deem inside of the boy.
Having spent the boy and the man the bear grabbed each one under a massive arm and took them back to his house.
Locking him in a cage he saw the boy laying on the bed his abdomen extended as if he had a beer belly but that wasn't there a few hours ago.
His sperm was now so potent that he impregnated anyone he had sex with and the bear was happy to take advantage of that capability.
