Levi stopped and reached for the condom he left on the table. After several attempts of opening it with his wet fingers, he started looking for a towel. But this is a situation taking place in Levi's office, he obviously has no towel.

"H-Hurry Levi! I need you!" Eren moaned, suddenly acutely aware of the handcuffs restraining him from helping Levi. Levi's absence also caused goose bumps to erupt along Eren's skin, for the sudden loss of heat and friction left Eren cold, the lotion now freezing.

Levi glanced up at Eren, still blushing in his dirty pose, and pulling against the handcuffs.

'Damn it,' Levi sucked Eren's juices off his finger and ripped open the packet, quickly putting it on himself. He grabbed Eren's back and grinded forward and backwards, teasing Eren's hole with his head.

'Damn kid, making me react in a way I'm not used to. This brat is too damn flexible to anything I throw at him. Mention fucking Mikasa, and he's fine with being fucked instead. Put him in handcuffs? He'd put them on himself if I asked. Where's the fun, or the challenge?' Levi thought. He enjoyed being able to rub himself along Eren's backside, hear Eren moan and need for him, but he fought for everything worthwhile in his life. Eren's on a fucking silver platter and Levi was unsettled at the prospect of having something for free.

"Levi please!" Eren even started shaking his ass in Levi's face and tried to push Levi into himself just through grinding.

'Perverted freak,' Levi sighed as he gave in and pushed himself into Eren, waiting for a moment for Eren to adjust. The excitement Levi felt watching Eren touch himself fully clothed on the chair had left. Levi was just tired of it now. He'll fuck the boy and move on with his life.

"Aahah," Eren sighed and moaned, not even minding Levi's big length pushing apart Eren's ass. Without warning Levi started pushing into Eren, a quick speed that even brought flexible Eren moaning and wincing, feeling but not complaining about the pain. Levi's strong legs clenched his butt and he set an extremely quick pace, holding tightly onto Eren's hips as he did so. Levi had given up on playing games with Eren if he was the one losing. His plan was to fuck a flustered boy and have dominance over him, but it was pointless if Eren wasn't even going to participate and give back.

'Although maybe I just expected too much from him,' Levi thought, a slight disappointment furthering his bad mood. Wanting for both of them to finish quickly, Levi continued with his pace and it wasn't even a moment before he was slouching onto Eren, coming, while Eren screamed in pain and euphoria as he came again.

Levi paused for a moment, catching his breath, then removed himself, ignoring Eren still twitching in front of him, removed his condom and put his pants back on. He reached for the handcuffs keys, and let them go with a click.

"That's it for endurance and obedience. You are to meet up with Mikasa now to continue your physical training." Levi said briskly, putting on his fallen shirt and smoothing out the wrinkles.

Eren collapsed in front of the bookshelf, panting and feeling a pain in his ass. The sweat caused his hair to stick to his face and his underwear was still dirty from his first round. He went commando, but stopped by Levi's desk before he left.

He leaned down, and kissed Levi full on the mouth, dipping Levi's head back and using his tongue to tease Levi open and taste him.

"Thanks for the training sir," Eren whispered, his eyes still glazed from their past experiment.

Levi sat at his desk for a minute.

'Shit I guess I need him back for some more lessons now.' Levi thought, glad that no one was in the room to see his blushing face and smile.

Author's Note:

Okay so I wanted to write this earlier but I was in such a slap happy mood that I knew if I started writing I would compare someone's ass to pancakes. So I didn't. And the at first I didn't like how I was writing this chapter, but the ending was perfect so I don't care. Please review so I can improve on my writing style!
