Stein's sexy! Did you see his body when he was shirtless and started to train on that plateau? God damn! But that dumb bitch had to appear and started to molest him! Grrr... Medusa!
The room was dark and black as the Demon God's madness started to take over Stein. When he looked up at his computer screen his work suddenly turned red and he could see the Demon God's three decorative eyes staring back at him. Stein instinctively pressed his face against the screen, and the three eyes were copied on his face. Going insane, he started to type more and more, resulting in the same deranged red print on the screen.
"Ehh?" Marie asked as she flicked the light switch on. "What are you doing in the dark?" she asked. She walked into the room.
Almost instantaneously, before Marie could notice, Professor Stein returned to his normal demeanor. He didn't respond.
"Stein-hakase?" Marie asked in an unsure tone. "What's wrong?" She stood behind him.
The madness is taking over me... Shit! Stein thought as he tried to fight against it. The pain he felt was unlike the usual ones he would feel every now and then. The madness of the Demon God was about ready to engulf his entity.
Marie leaned over to see his face when Stein suddenly slapped her.
"Ah!" Marie gasped in pain. She was on the floor with her hand covering her injured cheek while her other arm supported her body. Her lips were trembling from fear and shock. Marie would've protested, if Stein wasn't giving off such a creepy evil aura. "N-Nani?" was all she was capable of saying at the moment.
Stein spun around in his chair and slided over to Marie. When he did, he laughed insanely. Stein lowered his hand down and held Marie's cheek. He smirked. "Are you afraid...?" Stein asked.
Marie just looked up in terror. "Stein-hakase?" she asked once more.
"Hahahahahahaha..." Stein started to freakishly laugh again and caressed her cheek. The madness was taking over him. He couldn't stop laughing.
The blonde tried get up and run, but Stein was now out of his chair. He grabbed Marie by the both hands and held them extremely tight. He was almost cutting off her circulation. "I said..." Stein started, "are you afraid?" He then slammed her on the large table. All the test tubes, cups and implements Stein had fell and scattered across the floor.
Marie would've covered her eyes if Stein hadn't been holding them. "S-Stop!" Marie said, tears streaming down her face. "What are you doing?" she screamed.
Stein chuckled evilly. He removed his hands and Marie tried to move them. To her surprise, though, her hands were chained to the table. He leaned down and whispered, "You're going to enjoy this, Marie-chan."
There was a long zipping sound.
The Death Scythe was paralyzed in fear. "Don't..." she whispered. "P-Please, Stein-hakase!"
Stein smiled.
"AHHHH!" Marie screamed as he penetrated her.
Yeah, that was short. I wanted to make a one-shot (if that's what you call it), and that's where I ended. I know that Stein was Marie's first love while they were still in Shibusen, but now they're just close friends. So, Marie doesn't really 'enjoy' it. Not yet, at least. The rest is up to your imagination ;)
