*present day*
1. Introduction
35...36...37...38- Shit, this was a lot. Saitama squinted bloodshot eyes at the cracks in the ceiling drywall. Probably from the time when Genos tried to kill that mosquito. It had caused quite a mess, which was a pain, but Saitama honestly despised bugs, so he couldn't really blame the kid. 39...40...41...
The fourth round of the exercise finally seemed to be granting its desired effect as Saitama felt the telltale heaviness in his eyelids and fogginess in his temples that signaled sleep- divine, blissful, elusive sleep.
The hero smiled softly as his mind finally slipped into the abyss of slumber, heavy exhales (Saitama was a bit of a mouth-breather, at least according to Genos) gradually evening out and deepening, deepening, until-
"Hhnnggh..."
Saitama shot up, back ramrod straight and pupils dilating in the dark. All of sleep's wonderfully encompassing shadows had been torn from the hero's mind, leaving pure irritation to fill the tragic occupancy.
Oh, come on! Again?!
"Nnngh~"
A second moan emerged from the blanket-covered lump to Saitama's right, a lump that was now steadily emitting a soft orange glow and a heavy whirring sound.
Fucking hell. He knew Genos was a teenager and all, but this was getting a bit ridiculous. Tonight made three nights in a row, and Saitama needed his rest, dammit!
Saitama wasn't an emotional man, but upon reflection on his recent loss of sleep - sleep, one of the few activities he truly cherished - the hero felt a hot surge of rage and had to calm himself down.
No! You will not kill your disciple. You like Genos, remember? He respects you and always backs you up, and cooks and cleans and...
"~pleasee!"
...and has wet dreams.
"....please, Sensei~”
Saitama's heart stopped, actually stopped.
Wet dreams... about ME?!
As eternities in the form of seconds passed and quiet filled the small room yet again, Saitama exhaled a nervous "heh", all the while keeping an eye on the luminous blob beside him.
There was absolutely no way Genos had said his name, right? Right?! He was crazy tired; maybe he’d just imagined it for some weird reason. After all, the kid boasted a large fan club filled with beautiful girls—there was no way Genos would get off by thinking of some old, bald guy like him. Yeah. Definitely all in the dome!
Satisfied with his reasoning - and seconds now seeming to last only as long as advertised - Saitama's heartbeat calmly returned to its default low, steady thrum.
Time to try to sleep again, I guess, Saitama thought a bit blurrily, blessed shadows finally creeping back. Until-
A whispered "Sensei,” characteristically reverent yet unmistakably full of desire, filled the quiet of the room.
Shadows yet again fled from Saitama's bald head, this time replaced with a catastrophic mix of disbelief, shock, denial, a baffling tinge of sympathy, and an even more confusing flash of... excitement? And Saitama would be lying if he said he wasn't a bit weirded out.
Genos was actually having a sex dream about him! But why? This was Genos! The darling of the Hero Association! Everyone's favorite, the cool and handsome Demon Cyborg. He was the stuff of pubescent dreams, not Saitama! Holy fuck, what should I do? Should I say something? Maybe I should, uh, should....
Despite the gravity of Saitama's discovery, three nights of little-to-no sleep had taken their toll on the hero. Genos was finally silent, apparently having apparently accomplished his happy ending... good for him, I guess... and Saitama again felt himself drifting off.
Before he became completely lost, though, a solitary thought swam in the corner of Saitama's mind.
I wonder if it'll happen again tomorrow night...
