As the hot cum gushed in endless spurts down Tony's throat, he noticed a strange feeling in his groin.
Lost in euphoria though as he was, he ignored the tingle, putting it down to his body trying to keep up with the excessive amount of cum he was expelling all at once.
Tony kept his attention focused on his constantly exploding dick, which was now expelling such large loads of cum that quite a lot had to escape Tony's mouth and dribble back down his shaft and balls like thick white paint.
The tingling became stronger though..
And began to become like a painful but pleasurable sensation around his groin area.
One of Tony's hands reached absent-mindedly for the sensitive spot just left of the base of his groin.
There seemed to be some kind of bump there..
Tony examined it further.
It wasn't just a bump either.
It seemed to be throbbing like it was alive or something..
Tony was confused but not overly alarmed.
Until his hand moved down to his balls and noticed something that shocked him.. there were now four huge, bloated testicles hanging between his legs!
"TONY LOOK!" cried Branden in awe from below, pointing at Tony's groin.
Tony followed Branden's line of sight until he saw his penis.
Not just his penis though.
Another little penis was sprouting right next to it, about a fifth of the size of his normal dick.
The bump he notcied earlier was actually another penis growing from inside him!
Tony watched as his second penis rapidly inflated until finally it blew up to the same gigantic size of his first penis, fully erect and dribbling precum, while his first dick was still spewing forth cum.
