".... swap bodies with you, son." "Wait, really? You want to be me? And you want me to be you?" "That's right. What do you think?" "Well... um..." To tell the truth, Jeff wanted a chance to become his father. His massive body wasn't perfect; it was partly more fat then pure muscle; but his cock was massive. What it lacked in height; Jeff's was longer; it more then made up for in pure girth. Just thinking about it made Jeff hard, not that he was gonna tell his father that. "Sounds okay to me..." was what came out his mouth. "Really?! That's great son!" "Don't know what you want with my body, but sure thing," Jeff replied as he went to the Chronivac to make the changes. "Oh, when you get to a certain age, you start to envy the youth." Jeff paid little mind to his dad as he excitedly, but not showingly, went to work.
There was no body swap function, so he had to bring up both profiles and make the changes manually. He replace his stats with his father's and after making sure they were right, replaced his dad's stats with his own. "So I guess, this means we won't just be swapping minds, but have our bodies change too?" "Looks like it." "God this is making me so hard!" Jeff added in his thoughts. "I hate to admit it, but I'm kinda getting hard just thinking about it." Evidently, while he was embarrassed to admit that, his Dad ha no such conniptions. "Jesus Dad! I'm your fucking child!" "Oh like, you aren't hard yourself!" "Ugh! Can't wait to be you! You can use some of my modesty!" "That so? Well I can't wait to be you! I"ll use this body to my hearts content... And this is a silly argument, isn't it?" "Yeah, it is," Jeff replied back immediately. "Then, come on! Come on!" "Okay, okay... Jeez, who's the child here?" "Well, soon it will be me!" Mike quipped. Jeff made sure the changes were right and hit enter. A few moments later and a countdown from 1 minute appeared on screen.
"Here it goes!" Mike said excitedly. "Yeah, it does... Oh yeah, I should take my clothes off. Don't want to rip them," said Jeff as he got undressed. "Good idea!" Mike added as he started to take his off too. "Oh, you don't really need to..." "Now I can't let my son brave the changes in his birthday suit alone!" Mike replied back as he fully undressed himself. Jeff soon followed after, leaving father and son buck naked with each other, each sporting a massive hard on. "Jeez, Dad. You don't know how lucky you have it." "Oh, you'd be surprised. Having such a massive cock isn't always the best. And yours is nothing to scoff at," Mike said as he touched Jeff's dick. "Hey, don't touch it like its yours!" "Oh, but it will be soon enough! Here. Why don't you touch mine?" "Ew and gross!" "Like you aren't hard just thinking about...!" But before their silly argument could continue, the timer hit zero and the screen said, "Transformation Proceeding! Beginning scanning process!"
A red light shined from the Chronivac and scanned both Jeff and Mike from head to toe. "It tickles," Mike said. "A little..." After that was done, the screen changed again saying, "Scanning Complete! Beginning changing process!" "Here it comes!" Mike said. A few seconds passed... "Um... I don't feel any different, do you?" Jeff asked. "Um..." Mike looked over his body and then at Jeff's. "That's strange... Don't tell me its broken..." Mike finally said as he moved to the machine. As he did, Jeff felt something surge from within him. "Oh!" "Jeff?" "Um... I... I feel kinda funny." "Son...? Oh!" Just then Mike felt something too. The same surging feeling. "Oh my... Oh my god! Jeff?!" "Dad?!" As the two called out to each other, Jeff began to grow and his Dad shrink. There was a three inch difference between them, but Jeff was steadily getting up to his Dad's eye level. Soon he was at eye level. And then Mike was staring to have to look up! "Holy crap! I'm fucking taller then you, Dad!" "And I'm fucking shorter. This is really happening!"
"Oh god! Dad?!" Jeff yelled out. He was excited, but slightly fearful as he would soon become an adult. "Don't worry son! This is gonna be great!" Mike said as his body started to decrease in weight. Fat and muscle were fading away, but new muscle was also forming in different places. "Holy crap! This is amazing!" "Dad!" Jeff yelled out again as he gained weight. Muscle and fat forming all over him. "Oh god! I feel so weird!" he said. "Me too! Oh god!" "Dad?!" "Oh... wow! I feel so weird. Woah!" Mike felt faint as he lost balance. Jeff reacted and caught his Dad in his growing arms. As he held onto him, it was getting easier to hold him up. He could feel his Dad get smaller, his arms thinner. He had a lot of body hair, but it was fading by the second. In its place, Jeff was gaining plenty of body hair, its wispy strands tickled Mike's much smoother skin. "Dad, you okay?!" "Yeah, I'm fine... Just... Ugh... Oh god! I feel so fucking horny!" "Dad?!" "Oh god! Son! Son!" Mike moaned as he hung onto Jeff. They could both feel their feet changing under their won weight. Mike's shrinking feet sunk inwards, while Jeff's growing feet pushed forwards. He could really hold his father now.
"Oh god! Jeff!" Mike yelled as he pulled Jeff down to their knees. "Jeff! Jeff!" Mike simply repeated his son's name as he grabbed his son's much bigger hands and stared jerking his own dick off with them. "Dad! What are you?!" "Don't stop! Oh my god!" Mike yelled out as he pumped Jeff's dick furiously. "Ah,ah,ah,ah,ah! Dad?! Dad?! Oh,ah,ah,ah,ah! Jesus!" "Jeff! Jeff!" Mike simply repeated his son's name as he continued to jerk his son off. "Ah,ah,ah,ah! Daddy! Holy crap!" Jeff could no longer contain himself either as he started jerking his Dad off in earnest. "Ah,ah,ah,ah,ah! So good! So good! Jeff! So good!" "Ah,ah,ah,ah,ah,ah! Dad?! Daddy?!!" "Ah,ah,ah,ah,ah! Do you, ah,ah,ah... feel it. This dick will be yours soon! Ah,ah,ah,ah,ah! Ahhhhhh! I'm gonna!" "Ah,ah,ah,ah,ah,ah! Me too! Me too, Daddy!" Ah,ah,ah,ah,ah,ah,ah,ah,ah,ah... AHHHHHHHHHHHHHHHHHHH!!!!" Both Mike and Jeff let out a beastly roar as they ejaculated onto each other. Their roars mixed together and changed. Mike's got higher, while Jeff's lowered considerably. "Gah!!" They both let out one more short outburst as their cum stained bodies fell down on their backs.
As they both laid panting, their dicks; which were still hard as diamonds by the way; changed. Mike's got longer, yet much thinner. The healthy veins of a sixteen year old boy were plainly visible. Jeff's got shorter, yet doubled in weight. So much so, that it felt like it was gonna collapse on itself. Was this what his Dad meant by his cock not being all that great? Well it mattered not, because Jeff took it in his big meaty hands and jerked off himself. Mike soon followed suit. They had been holding the same dicks before, but now it was on their own bodies instead. "Ah,ah,ah,ah,ah,ah! Dad!" "Ah,ah,ah,ah,ah,ah! Son!" "Ah,ah,ah,ah,ah,ah! No! Son!" "Ah,ah,ah,ah,ah,ah! No! Dad!" "AHHHHHHHHHHHHHHHHHHHHHH!!!!!!" Another beastly roar and father and son, now son and father ejaculated once more.
