After practice Jeff was exhausted, inspite of being in good shape, his new fat legs werent, and made him struggle through the whole practice. He avoided taking a shower because he didnt want to draw any more attention anf headed home forgetting to return the speedo to his coach.
Whe Jeff got home he headed to his room and was shoked to see his dad laying on his bed wearing only a shirt but it was raised behind his neck exposing his hairy chest while stroking what seemed to be a small penis which was already soft and coverd in cum.
Mike jumped at the sight of his elder son and tried to cover his tiny dick, but it was too late, Jeff had already seen him and knew who he had swapped with.
"dad what did you do?"
"I... it's not what you think Jeff"
Jeff hurried to the chronivac to find the 3 pictures of his dad, Jacob and him with their lower halves swapped. all the option in the screen were still locked for the exception of the "add subject" option, they wont be able to swap until the end of the week.
"so we are stuck like this until next week?" asked Mikee after Jeff explained everything to his dad.
"well yeah, asically"
"Well im not going to ask why you wanted to check on your brothers manhood, but now you know who the real man of the house is"
"yeah dad, its me, my dick is bigger than yours"
"Im not talking aout now Jeff, im talking about our respective dicks"
"Yeah I know, and mine still bigger than yours"
"oh come on Jeff just look at yourself, you now have a real dick between your legs"
Jeff had been trying to void thinkingaout it, but now, still looking at his dad with Jacobs's legs and knowing he had his dad's, his dick (or his dad's dick between his legs) started to grow a boner from under his pants.
"I think theres is somethign that demands your attention Jeff, Let me show you how you should play with my cock" said his dad while playing with Jacob's tiny dick.
Soon both of them were laying on the bed completely naked, jerking each other dick.
After cumming a couple times on their bellies, Mike looked at his son and asked " Hey Jeff I was wondering if you would let me try something"
"what is it dad?"
"well I always wanted to see my cock being covered in someone elses cum but now that..."
The idea of having someone else's cum on him made Jeff even more excited and he inmediately accepte his dad's offer, besides it would be his dad's dick covered in Jake's cum, Jeff would never let his lil brother cum on him. "Yeah dad lets do it"
Mike then moved on top of his son who was still jerking his dick. The 40 year old stroked his tiny weiner with his thick hands until he came on top of his former cock, moaning with every spurt until there was only a string of cum leaking from his teenager dick.
"oh fck that was good, havent had an orgasm like that in years" said Mike as he layed next to Jeff.
"nows my turn dad" said Jeff moving on top of his dad just like he did minutes ago, and started jerking his thick 5" using his dad's cum as lube (or was it Jacob's? Jeff didnt care, he was really horny)
Jeff came faster than his dad, a shot of sticky white/yellowish cum came out of his cock , not just falling on his dad tiny cock but all over his belly.
