BONUS CRACK DRABBLE:
"Sensei! Is that.. Is that a child?" Genos shouted when the egg-like capsule broke.
It had been a rather ordinary day, and Saitama was just contemplating pulling Genos down and teaching him the art of patience through sex when a loud explosion occurred right outside their apartment.
An egg-like capsule had fallen from the sky, hitting the streets. They had been staring at the thing, wondering what to do when it started cracking.
Saitama stared at the child that suddenly burst from the egg. There wasn't any other word for it. A giant egg had fallen from the sky.
The child couldn't be more than 2 years of age at most, and he was terribly dirty, coated with the slime from the egg and bits of shell.
The child started crying, and Saitama went to pick it up. Upon picking the baby up, he stopped crying immediately. "PAPA!" the child screamed, hugging Saitama tightly.
"OI!" Saitama cried out. "I'm not your dad!" he turned the kid upside down, twisting him from side to side, trying to determine if it was an alien or monster-in-disguise.
"Don't call Saitama-sensei that!" Genos came closer. The naked child squirmed in Saitama's arms. "MAMA!" the child screamed this time, small grabby hands reaching out for Genos.
"What the hell!" Saitama yelled out. This was getting surreal.
"Don't swear in front of the kid sensei!" Genos quickly said, his face cracking up into a wide crazed smile when the child called him 'mama'. He took the child from Saitama's arms, and cuddled him close, crooning at the child.
Saitama only stared at the two of them with crazy eyes. This couldn't be happening. He sighed, smacking his head hard. Saitama could foresee a bunch of crazy things happening real soon.
"Aren't you a cutie Genosai?" Genos babbled at the child.
"DON'T NAME THE CHILD GENOS. WE ARE NOT KEEPING HIM!"
"But sensei!"
"And what sort of name is Genosai anyway?"
"It's our love child sensei! A product of our love!"
"NO."
