Caleb wakes.

Caleb awoke to find his hip pumping and grinding the air above. He was moaning loudly and a fountain of cum was erupting from his hot, swollen cock. The mattress around him was soaked with sweat and cum, and as he slowly came down from the massive orgasm he'd had, Caleb realized something wet was dripping onto his face from the ceiling above.

"Is that... cum? I jizzed so hard I hit the ceiling?" He was incredulous. He was covered in an impossible amount of semen. If he was guesstimating, it was at least of full cup of ejaculate, but that was... impossible.

Lazily, he stroked his fingers through the pool collecting on his torso and licked it up. Then, realizing what a mess he made, and how awful it would be if it soaked into his mattress, he got up and started cleaning up his mess. He wadded the bedding up and shoved into his hamper; he could do laundry later. He wiped up what had soaked through to his mattress as best he could, then headed to the shower. He needed to be at work by 11:00, and it was already 10:30.

In the shower, Caleb soaped up and scrubbed off quickly. As his hands roamed his body, he thought he felt... tighter--more trim. And... maybe more muscular?

He soaped up his nuts and his cock. His balls felt huge, maybe twice as large as usual. Looking down, he saw that they were indeed bigger... like, not quite tennis ball sized, but close. Well, maybe not even that big. I mean, I've always had pretty big nuts, I guess. He managed to convince himself that they were their usual size, or at least, only a little bigger.

Caleb's dong was bigger too--substantially bigger. He hung soft at about 8.5 inches long and his dick felt about as big around as a coke can. Still a little chubbed up, I guess, he reasoned.

The truth was that Caleb was growing. He'd put on about ten pound of muscle, most of it in his chest, shoulders, and ass. And the growth to his junk was happening even more quickly.

If he'd have stopped to look in the mirror, he'd have noticed that his features had hardened a bit. He was looking a little more masculine. But as it was, Caleb didn't have time for examining himself in the mirror. If he didn't hurry, he was going to be late for his tutoring gig.

Caleb threw on a pair of grey joggers and a tshirt. He planned to follow his usual Saturday morning routine of tutoring at the library before taking a jog around town on his way home.

He was out the door in a flash, and except for the few sideways glances other passengers on the subway gave his bulge, the ride to work was uneventful.
