Jason watched in awe as his dad's body seemed to ripple, like dropping a stone in a pool of water. Jason was sure what to expect, whether or not the transformation would be fast or slow. He had hoped it would be slow, so that he could savour every moment, but as the changes started Jason realized that it would only be a matter of seconds before the transformation was complete.
Michael was a burly bear of a man. He was on the football team in his youth and, although those powerful muscles lost their definition over the years and were covered with a heavy layer of fat, he had always carried around alot of girth. After about five second, all of that girth and fat fizzled away, leaving him very lean and taught. His skin tightened and became more youthful, a light full body tan spreading over his pale torso while his weathered arms and face lightened up.
Michaels pants and underwear fell straight to the floor now that his large gut and massive bubble butt had vanished. Jason gasped at the sight of his father's thick, hairy cock exposed to the air. The sensations Michael was feeling must have been intensely erotic because his cock was hard and red, pulsing wildly. Jason has a pretty decent cock at 8 uncut inches, so he was a bit surprised to see that his dad's cock was pretty small, maybe only 5 inches. It was pretty fucking thick, though. Michael moaned in pleasure as his cock slimmed down but lengthened up, looking to be the same length as Jason's cock.
Jasons cock, which had been semi chubbed at the whole ordeal, now rocketed to a painfully hard erection as he realized that his dad was transformating into himself! Jason remembered his dad ruffling his hair after dinner, so he must have been the last person his dad touched!
Just as Jason had this realization, he watched as his father's face rearranged to look exactly like his own! It was so bizarre for Jason to see himself standing in front of him. It wasn't a reflection, either, so it was really weird to see his reflection but he looked backwards.
The last part of the transformation was his dad's body hair. Michael was ridiculously hairy, with tufts of hair covering pretty much his entire body. Jeez, even his dad's cock had hair growing halfway up the shaft and his lives were ridiculously out of control. Jason, however, was practically smooth. He had a light treasure trail running down from his naval to his crotch and a light dusting of fine, blond pubic hair but that was it. Jason watched in glee as his fathers body hair practically vanished.
Jason couldn't help but stroke his dick through his shorts as he stared at his newly transformed father. Jason really wasn't vain, but he knew that he was a delicious yum yum. He had a nice taut swimmers body, a long cock and a models face.
"What the fuck just happened?" Michael said wildly, his breath ragged from shock and exertion.
Jason couldn't help but smile, even his dad's voice had changed to match his own. Jason pointed towards the large mirror over the fireplace. "See for yourself."
Michael gasped in shock, his hands touching his face and running over his body as he stared at his new reflection. "Jason," he said in awe, "I'm you!"
Michael looked down at his erection and smiled as he gripped it with both hands. "You're quite the big boy aren't you?" He said with a smirk.
Jason's cock was throbbing, a dark spot forming on his shorts from the pre-cum leaking out of his painfully erect cock. His dad looked so fucking hot and he was clearly just as turned on as Jason was. Jason's libido was really high. He thought about sex constantly and had to jerk off sometimes two or three times a day. His dad knew Jason was gay, but what he didn't realize is that Jason was more or less a power bottom. While Jason occasionalt enjoyed topping with his big dick, he usually liked taking it up the ass instead.
Michael seemed to be lost in the sensation of a young man's lust. He was now stroking his cock pretty seriously right there in the living room, right in front of his own son. "Jason," he said erotically, "I'm so fucking horny. I just can't help myself! Are you always so horny?"
Jason pulled his shirt off, pulled down his shorts and underwear in one swift motion and tossed himself against his father's sweaty body. He felt his dad's hot, sweaty cock pressing up against his tight stomach as he drove his tongue into his dad's mouth.
His dad moaned loudly as the two passionately kissed. They were both ravenous as the kissed loudly and slopily.
Jason reached down and grilled both of their cocks with his hand, sliding up and down, squeezing and pulling just the way he liked it. Jason was feeling a familiar tingle in his hole, a desperate longing to be filled. Imagining his dad was also starting to feel the same tingle without understanding what it meant, a wicked thought flashed through his mind.
He was going to do it. Jason was going to fuck his dad.
