50 Shades of Ereri

Hanji's Experiments: Heat

Eren sat patiently, or as patient as he could, as Hanji was conducting another one of her experiments. It had been a long day and Eren was ready to hit the hay.

"Okay," Hanji said, "I think it should be ready now."

Eren gave a sigh of relief. "And you're sure that it's safe?"

"More or less." She gave him a few drops of the mixture she made. "Okay, now what this should do is work while you're in titan mode. It should help reduce the amount of heat you give off so it won't damage your physical body."

"Right."

"We will continue this tomorrow. You can retire for tonight."

Eren got up. "Thanks. Goodnight."

"Night."

The next day of training consisted of multiple tests of Hanji's experiment. However, only when he wasn't in Titan mode, Eren would get incredibly hot...and a little horny. Even reliving himself barely helped and he was faced with the cruel reality of telling Hanji.

"Maybe it's just a side affect. The reduced Titan heat probably has to go somewhere else," Hanji said.

"But," he blushed, "do you know how hard it is to get an erection every hour and trying to hide it?"

"No, but I'll try to find an antidote. Just wait a few hours and try taking a cold shower to help."

"Okay." He left, only to run into his captain. That's what made matters worse. Because of Eren's huge crush on Levi, just so much of the thought of the man made Eren twitch and throb. "Oh, e-excuse me." He tried to leave, but Levi grabbed his wrist. His strong grip made Eren's thoughts and possibly Levi's hand run wild all over the place. He mentally cursed at himself for being so dirty.

"Where have you been?"

"I was just with Hanji." Eren refused to look at him as he tried to escape. Levi only held tighter. Damn his grip. I wonder if he could grip other things the same way.  Eren blushed harder. He needed to escape before things got too out of hand. "Sh-she told me to take a shower."

"Tch," he said, letting go. "If she's telling you to take a shower, you must be filthy. Hurry up."

"Yes sir," Eren said, walking away as quickly as he could.

Neither the cold shower, nor avoiding the Captain as much as possible didn't stop Eren from jacking off at Levi's name. He grabbed his throbbing cock and shivered. Why couldn't this be the captain's touch? he wondered. His hand moved up and down. As he progressed, his breath became heavy. He imagined his captain doing these impure actions to him. Eren moaned. "Ah...Levi..."

"You've got some nerve calling your captain by his first name." Eren turned to see Levi on the other side of the bars, a hue of pink dusted on his pale face.

Eren looked at him. He was embarrassed, no doubt, but he didn't care. He was in far too much pleasure to stop. He just stared with a crimson face as he continued his actions.

A glisten of lust appeared in Levi's eyes before he opened the cell. "Fuck," he said under his breath, "are you trying to turn me on?" He walked over to Eren and hovered over him on the bed. Levi gently nibbled on Eren's neck.

"Ah~"

His hand traveled to Eren's erection. He began to slowly pump it. His grip tightened as his strokes became rougher.

Eren's back arched as his mouth filled with saliva. "Mm..."

Levi's thumb rubbed and circled on the tip, making Eren spill cries of pleasure. He moved down and put Eren into his mouth. He gently sucked and licked along the shaft.

Eren rocked his hips forward. "Nng..."

Levi swirled his tongue around the tip. His hands grazed about Eren's hips and torso. He sucked harder.

Waves of pleasure filled in Eren and he reached his climax. Eren's cum filled Levi's mouth and he swallowed. The two caught their breaths before locking lips. Eren tasted his seed as his and Levi's tongues swirled around in a blissful harmony.

Levi pulled away. "I did come here for a reason." He reached into his pocket and pulled out a small vile. "Your antidote."

Sorry about the chapter. I'm a little rusty because I haven't written smut in a while. Also, I'm writing a new fanfic! The first chapter will be up after Rejection 10 is updated!
