As the chronivac’s countdown finally reached zero, Tyler felt a growing heat in his crotch. It felt like a pleasant warmth and tingling around his crotch. It slowly got hotter and hotter, but it still felt pleasant. What was happening? What is the change the chronivac is initiating?
The pleasant heat extended down into his balls too; it felt great. Tyler let out a moan at the feelings in his crotch. It felt like he was getting turned on. He could feel his dick start to stiffen.
Tyler quickly unbuckled his pants and dropped them to his ankles. Tyler took the boxers off too; he had to see what was happening down there! He could see his cock, nothing looked different about it, except that it was throbbing and so very hard. Beads of precum dripped from the tip. How was he so horny? What was happening. His balls, likewise, felt like they were throbbing or pulsating with the strange heat.
That was when he noticed it. With every throb and pulsation of his dick, it looked like it was getting a tiny bit bigger, ever so slowly. Tyler stared for a few seconds just to make sure. “Holy shit!”, he muttered to himself, it was getting bigger! It was already about an inch bigger than it usually is, and only getting longer and thicker. His dick felt to hard and so full that expanding and growing bigger was the only option. Reaching down, he cupped his nuts. They felt bigger too. Resting in his hand, he could feel them pulsing and growing ever so slightly bigger, too.
There was a mirror in the bathroom that he could use, so he quickly grabbed his boxers and jeans and ran naked to the bathroom, his large boner warring side to side, idly dripping precum on the carpet.
By the time he got to the bathroom and got the door shut, he looked in the mirror. His cock was extending from his body like a steel pipe a good 10 inches. “This is crazy!”, he thought. Was it him, or did his cock also look quite a bit darker? His now lemon balls, likewise, were hanging lower in their sac, which also appeared darker as well. What the hell is going on?! This isn’t normal!
Tyler reached down and experimentally gripped his cock. He almost gasped at the sensation; it was so sensitive! His hands slowly rubbed it up and down; the skin felt strange! Tough and leathery. His cock’s girth was so much more than before, and his length was now pushing 11 inches, if not longer!
That was when he felt an intense pain coming from the tip of his penis! “Fuck!”, he yelled as he let go of his cock. He closed his eyes and grunted. It felt like someone was twisting the head of his penis roughly! When he looked down he saw what was happening; the head of his penis was deforming! The tip was flattening out! What the fuck was happening, it was starting to look inhuman! Likewise, he felt a searing pressure around the middle. He could see a ring shaped band of skin forming around his shaft about halfway down!
The whole while, the color of his cock was darkening. By now, his 13 inch long member was a milk chocolate brown. His balls too, now the size of small apples, were likewise the same brown. The skin had taken on a thick, leathery texture that didn’t feel like human skin! He also saw a bunch of loose, flappy brown skin bunched up at the base of his penis!
The pain coming from the tip of his penis subsided, but it left him with a completely deformed, plunger shaped head! It didn’t look human at all anymore! “What the fuck is going on!”, he said, as he shuffled out of the bathroom and ran towards the chronivac. He is gait was quite slow though, with his massive erection swinging back and forth and his balls wetly slapping his thighs.
That was when he saw the chronivac; a new window was up.

“Oh fuck. Oh no”, Tyler said in horror as he looked down at his rapidly swelling cock. He could see it now; the deformed head, the ever blackening and leathery skin, the baseball sized balls! He was even growing a sheath! To make matters worse, he was so incredibly horny.
“What the fuck am I going to do?!”, he said panicking. His genitals were already so far removed from being human, and so much bigger, but the Chronivac told him he was only 64% of the way there! His cock and balls still had a long way to go…
