Before he left, a thought dawned on Dan. Sure, he would enjoy a world filled with bears, but he had fetishes for other body types too.
He quickly sat back down at the computer with a thud and started typing away. Soon, he had input commands into the Chronivac to increase the variety of men to beyond just bears. Of course, Dan being as growth-obsessed as he was, the new mankind would still be jaw-droppingly huge in comparison to the pre-Chronivac world. However bears would be the only redhead subs now. Dan wanted big, muscular jocks, who constantly worked on their muscles in the gym, playing sports, and in bed, some of whom would be so covered in powerful flesh that their muscles almost rendered them immobile. However the blonde jocks would all be somewhat cowardly. Blonde hair jocks will be the equivalent of the redhead bears. However these would desperately desire to be denied sensory information and orgasm but won't have the self control to do so without a master ordering them to do so. Also they will desperately desire bondage for the feeling of helplessness.
He also wanted some twinks. But not any old scrawny twink from the world before: even the skinniest twink would look like he belonged on an Olympic swimming or gymnastics team from the old Earth. And a twink's cock would always be above average by this new Earth's standards. In fact twinks would have dicks at least as big as an average redhead bear. Also black hair twink's would be does while brown hair twink's will be subs. A twink's ass hole will be able to receive very large intrusion. Also twinks will be unusually tall. Dan got so hard thinking about a twink whose dick overshadowed the rest of him.
So hard that, before saving his changes, he had second thoughts about his own dick size as well. Yeah, a foot-long schlong was a god-send from the perspective of his old life, but he was well past the point of no return into this brave new world, and he decided he needed to embrace its new standards. Or maybe he just had trouble controlling his desire for MORE--he couldn't help it, growth turned him on. And so he pulled up his cock stats and adjusted them: 12'' became 24''. He thought about adjusting the standard curve so that he'd be average, but the thought of meat poles a yard long being a dime a dozen made him decide against it.
His underwear stretched to the limit over his hard cock, Dan pressed GO. Heat spread through his body as the changes took effect. His eyes became glued to his dick as it grew, and he was a bit disappointed that his underwear didn't burst into shreds due to the increased mass of his organ. Instead, the underwear just grew bigger to match its hefty occupant, Dan's world changing in tandem with him.
A quick glance into his room's mirror turned into a double-take as Dan realized another change. Apparently the Chronivac had added him to the portion of the population who were now jocks. He was still 6'1, and he probably was close to the 300 pounds of skeletal muscle that he had programmed in earlier, but DAMN was he cut. His gut was gone, replaced by not even a six-pack, but a ten-pack. A drastic reduction in body hair made them look even more defined, the deep ridges just begging for someone to lick them. He flexed a bicep and almost creamed himself as he saw it swell to inhuman sizes. His pecs, however, were the real show stopper: each one had to be bigger than his head, and a few prods of his fingers confirmed that his chest was all-muscle, with no trace of fat under the skin. These quick prods soon became not-so-calm gropes, and he quickly discovered how much more sensitive his big dick was.
It was time to go though.
