"It's not over yet, my boy."
Cellucci says with anticipation.
"That grey thing just begun it's function. Once your stomach finish digesting the formula, The real work begins...!"
It is true. Even after you changed into the middle-aged man, that grey formula keeps being digested inside your stomach. Finally, you feel the whole formula absorbed to your body. Realizing the digesting process is over, you burp without knowing yourself.
Once that grey formula has been digested, you suddenly feel sexual urge again. You strongly want to jerking off. You grip your penis and start to shaking your prick. And your movement becomes more and more rough, eventually your old naked body moves very dynamically. You see into the mirror, and there is one hairy mature Italian guy masturbating. It was disgusting.
'Oh god. It's not me. I'm not that ugly naked guy in the mirror...'
Cellucci smiles seeing your hopeless face.
"Don't be so sad. Your body is so handsome and manly. Good going, boy. It will be soon over. Keep jerking off!"
Your reason tells you to stop jerking off, but you instinct makes you keep masturbating like a brute animal.
"Uh... Uh..."
You moan with your new mature deep voice. It is strange that you saying word, but sounds are totally strange.
"I.. I'm cumming... I'm cum... Oh...! Oh...!"
You feel your testicles wanting to ejaculate your seeds. The Italian guy speaks out with joy.
"Yes! That's it! Your sexual stimulation and the final orgasm..."
Finally, your prick starts to shoot out the fluid into the air.
"...will complete your transformation!"
Your penis spits out thick white semen. Simultaneously, your body trembles and your whole struckture begins to reform...
