Jeff went to the chronivac and looked at his settings. Then changed his dad's body to be able to produce a huge amount of cum, he even set it to be extra sticky. Then Jeff looked at his dad's attributes in his teenage body and made his dick more sensitive but able to last longer.
" I think that's it" said jeff looking at the screen with his hand over his chin
He pressed enter and the change took place.
" Ok dad it's all set" Jeff stepped in his father's bedroom and saw his old self measuring his dick with a ruler
" What were you doing dad?"
" Oh nothing, I was just taking some measures..."
Jeff smiled thinking it was a bit weird that his dad wanted to know how long his dick was. Buy then remembered he just looked at his stats which is kind of the same thing.
Mike then stood in front of Jeff , there was a great diference in their heigh, Mike was a whole head shorter and he had to stand on his tiptoes to make his dick and Jeff's dick be on the same level.
"Ok I'm ready, just cum on me son"
Jeff then started to jerk his dad's dick it took him a while to reach an orgasm but when he did. He moaned shooting his hot load all over Mike's dick and hands.
Mike on the other hands started gasping with his mouth in the shape of and O . He jerked his much smaller dick and used the cum as lube.
It felt incredible, for some reason his dick was now more sensitive to his hand, his foreskin pulled up and down filling every single crease with what used to be his spunk. He was so focused on the feeling that he didn't even noticed how much cum Jeff had produced.
Slowly he backed away lying on the bed with his knees bent.
Meanwhile Jeff kept jerking his dick looking at his dad, for a moment he thought it would be awesome to feel the same thing his dad was feeling or maybe get another change to be fucked by his former dick. But instead, Jeff got
On the bed and crawled towards his dad who lifted his legs unconsciously.
Without a second thought Jeff rubbed his dick around his dad's ass, Mike looked at Jeff just before the boy in a man's body fucked his former self.
Mike moaned feeling his huge dick make his way inside his son's ass. But for some reason it wasn't as painful as he thought it would be. Instead it felt like if his body was used to it. He even wanted Jeff to go deeper as he kept jerking his dick with passion.
They kept moving and breathing rhythmically until Mike finally shot his load over his tummy.
When Jeff got his dick out, a huge amount of cum leaked from Mike's ass since Jeff had cum twice.
