The Heat stimulates them

................
Unbeknownst to Mike, the alien infection had begun to awaken due to the fluctuations from his shower. Further accelerating the problem was his constant mishandling of his penis while washing.

Not to worry though.

It would soon take hold...

................

Closing the glass partition, mike, started to towel himself off. He was planning his day out. What should he do...

Movies?

Gaming?

Football?

Or just stay home and chill?

These were weighty matters he was thinking about here. Such is life when one is the tender age of 22.

Discarding the towel, having finished using it, mike then brushed his teeth before leaving the bathroom. That's when he felt it.

"Oh god!" A rush of heat, along with a surge of pleasure moved along his lower body. "Eh!?" Mike saw his penis lengthen to an absurd count. It almost looked like one of his baseball bats. He was a little afraid to touch it now.

"To feel this good, it has to be okay, right?" Mike had a niggling feeling in the back of his mind that these words weren't exactly normal. But like smoke, it vanished on him before long. Staring once more at himself in the open door of the bathroom he thought he was just making a fuss about nothing.
