After a bit of looking at his computer, Jeff sees the option to turn into cum.
"Wow, you can even turn into cum? That is weird..." He says as he continues to stare at his computer while thinking.
And after a few more minutes of contemplating he goes and clicks on the cum option. 'It seems interesting at least so might as well try it.' He thought to himself.'
He then clicks random on who's cum he will become and skips some of the other stuff deeming them as unimportant and finally he clicks the enter button.
"I wonder who's cum I will turn into?"
He then starts to get a weird feeling that quickly spreads across his body and he suddenly starts to glow.
And then after a few seconds, the spot where Jeff was standing is empty, and the spots former inhabitant now is going into the ball sack of their new owner.
