Genos & Sonic TG - Monster Girl Obssession

I guess being monsterfied gave Genos a bit more "meat". To go along with it, a little story by  Flashkill 

"Sensei has no time for a weak villain like you! Leave or I'll not hesitate to destroy you.

"Pfft, like you could at that speed. I've been training for months to take him down."

A cyborg and a ninja danced at high speeds down the abandoned street; lasers and ninja stars flying in every direction. 

"Sensei has been training me as well. You stand no chance against the teachings of Master Saitama!"

"Baldy lessons are worthless and Iwill prove it by beating his student and then him. And I won't give up until I do!"

"Sensei would never lose to you! He's stronger, quicker and more skillful than a second rate ninja could ever hope to be. He's the greatest hero!"

"I've been studying his moves for weeks! Ive watched recordings of that bald loser non-stop. I probably know more about him than you! I'll defeat him I tell you!"

The two continued to squabble along much the same lines; Sensei, Saitama and Baldy being said over and over. The fight seemed to reaching a climax when-*BOOM!* their attacks hit a gas tanker left lying in the street. The explosion was close enough and strong enough to knock both the combatants out cold. And as they lay there a metamorphosis beganc

Sonic rose to his feet first. He held his head in pain as he tried to recall what had happened. "Saitama!" Was his first thought. He needed to find him right away. He began running as fast as he could. He felt a bit top heavy, maybe even a bit chubbier but he felt faster then ever before; like he could run so fast he would soar.

Genos's systems whirred back to life as he got to his feet. Sonic was nowhere to be found. "Master!" He cried out and began blasting toward his coordinates. Running a system check as he did so revealed many of his components were offline and yet... He felt stronger? He knew he had to consult with his master as soon as possible.

*CRASH* "Master!" "Saitama!"

Two buxom girls crashed through the roof of a bathhouse screaming for the same man.

"Fuck Me!" Both cried in unison.

"Master your training has paid off! I feel stronger. I know it may be out of line but, I think I know how to get even stronger! I need... your love! I want to kiss and cuddle and mate with you. Somehow my body just knows that way I'll get stronger."

"Saitama. Forget this bunny bitch, I want sex! Raunchy, Kinky, Violent, monster sex! And then I want to fight you! And then I'm going to want to fuck some more! And then maybe more fighting? Fuckings good too. Stop standing there and let's settle which one of us is on top once and for all!'

"Master! Cuddles!"

Baldy! Sex!

The hero stood there and said, "what?"

Research Later discovered this to be a new type of monster class. Many monsters were created from obsession but obsession in another person was rare. Genos and Sonic's obsession with Saitama has gotten so out of control that they triggered this transformation. Unlike other monsters their power was proportional to how much time they spent with the target of their obsession. The more intimate the time spent the stronger they got. Distance seemed to gradually decrease their strength although it was hard to test as the two would go into a frenzy of separate for too long. More research was necessary but the scientists settled on one thing, Genos and Sonic were now monster class: Succubus.
