Recap
He gulped and waited. "I dare you to sit on the captains lap and grind your ass on his crotch."

The whole room went silent..

--

"You...you want me to do what?" Eren asked as his face flushed and Levi's eyes were wide.

Ymir smirked and crossed her arms. "You heard her. Get to grinding."

Eren looked over at Levi who just shrugged and patted his thighs. Eren cleared his throat, awkwardly and looked back at Historia. "Do I have to?" She nodded while smiling. "Okay..." He muttered.

Eren got on his knees and held Levi's shoulders as he straddled him and sat down directly on his crotch.

Levi looked at Eren and shifted slightly.

"Try not to get hard, levi." Hanji said as she smirked and pushed her glasses up.

Levi just sighed and looked into eren's beautiful eyes. "Hurry up, brat."

"W-wait how long do I have to do it?" Eren asked as he turned his head to look at Historia.

"Hmm just 15 sec-" she was interrupted by ymir whispering in her ear once more. She nodded while giggling. " Okay nevermind. Until you get a boner."

Eren's eyes widened as he blushed. "Who even said this would turn me on?!"

Jean scoffed "Oh please..Jaeger we all see the way you stare at captain Levi. Don't even try to deny it." Everyone in the room nodded in agreement.

Eren blushed and looked at Levi who raised an eyebrow and smirked lightly. "Oh?" he asked seductively.

Eren shook his head frantically. "No I don't!"

Jean sighed "Do the fucking dare already Jaeger. You're taking forever." Eren rolled his eyes and took a deep breath.

Here goes nothing..

Eren slowly began to rock his hips against Levi's. He bit his lip as he noticed how good it felt. He never touched himself, so the sensation he was feeling was quite new.

"You look like you're enjoying yourself, brat." Levi said as he took notice of the lip biting.

Eren didn't respond as he started to grind faster and harder, directly on Levis dick.

"Shit, brat.." Levi said as he closed his eyes and began to get hot.

Eren let out a whimper as he felt Levi beginning to get hard himself. He could feel how big Levi was and could even feel how it twitched with excitement when eren's tip brushed against his.

"Damn this feels good." Eren whispered only loud enough for Levi to hear. Levi smirked in response and held Eren's hips, moving him faster as he thrusted up. His dick was sliding against Eren's clothed cock as they both were painfully hard now.

"You fucking turned me on, you damn brat." Levi said breathlessly. A bead of sweat made its way down his forehead as he continued to grind up against Eren.

"Oi, move your ass against my tip." Levi accidentally said a bit too loud.

Eren blushed and looked at Levi with wide eyes. "D-Dont say such lewd things, Captain." He moaned out as he followed the order nonetheless.

At this, Levi bit his lip harshly, almost drawing blood. He looked into Eren's eyes, then looked over at everyone else.

They all had shocked, flushed faces. Hanji on the other hand was biting her lip while watching. Levi found it weird so he just shook his head to rid his thoughts, and focused back on Eren.

"Love birds..the dare was to do it until Jaeger was hard, not until you both cum." Jean said as he rolled his eyes.

It was only then Eren realised that they indeed have been doing this for a while now. He blushed intensely and got off Levis lap, sitting beside him.

"D-done..." He muttered as he looked down in embarrassment.

Levi ran his fingers through his hair as he took a deep breath. There was a big tent in his pants, and everyone could see it.

Eren however, was covering his boner with his hands.

Levi looked over at Eren, "That wasn't too bad, brat."

The story isn't done, don't worry. I'm thinking about making this a full book, what do you think? Thanks for reading.
