Dylan knew he couldn't swap with his old body, it was against the family games' rules. He didn't want to swap with one of the other men in his family, even though the idea of changing bodies with his uncle Frank, and letting him enjoy being stuck in Kenny's tiny body, put a smile on his face. He wanted to be able to take care of Kenny in his old body, to make sure Kenny follows his daily gym routine, and diet, in order not to lose his hard-worked muscle. He went back into his room, and undressed to his underwear in from of the bathroom mirror. He started at Kenny's 6 years old hairless body, with a sad smile on his face.
"I'm sorry Kenny, but your body is too young for me to enjoy this vacation. My wish is to age 14 years." He was staring at himself in the mirror, waiting for the family magic to do its job and change Kenny's body. The change started with his feet, a tingling sensation started in his toes, while they grew bigger doubling in size. He grew taller, to 1.85 cm in height. His arms grew longer, with tick blond hair growing on them. Big biceps started to form. His pecs started to inflate with blond fuzz growing on them, then downwards a 6 pack started to form with a treasure trail going down to his underwear. His face started to mature, and his bone structure formed into a strong jaw. His hair started to grow longer and to form into a jock hairstyle. Finally, his underwear started to rip, with his butt forming into a nice bubble butt, and his dick growing from its old peanut size to a nice 6-inch flaccid dick. Finally, the transformation ended, and Dylan admired the stud that he was now. "Wow Kenny, not so bad, the family genes are great, but still you can see how much you worked to tone them. I think your future body is stronger than my own". He was touching his pecs, then his six-pack while watching himself in the mirror.
"Look who wants to play." His dick hardened into its full size of 11 inches. "I'm sorry Kenny, but I'm going to enjoy having your first orgasm in this strong body". Dylan started masturbating, thinking of his boyfriend, and how much he would enjoy fucking him with Kenny's 20-year-old body. He took his phone and texted his boyfriend the address, saying that he misses him a lot and that he should come to visit over the weekend. He looked at his boyfriend's Instagram photos, the most current one being a shirtless gym photo, and climaxed on the spot. Right then, someone entered Dylan's room.
