'Ah finally' Jean stepped into the cabin, closing the door behind him. The moon was already in the night sky and sent rays of white through the window. He'd been stuck with kitchen duty again. It was ridiculous how much one squad could eat.
Climbing up the ladder to his bed, the one that sat parallel to Eren who was already sleeping, curled up on his side. Eren seemed to silently mutter something in his sleep. Jean dismissed it, he was too tired to care about anything Eren had to say at the moment.
Jean quickly got into his own bed, getting under the covers and resting his head on the pillow. It wasn't the softest thing but it was a bed and there was a roof above him. Closing his eyes, he already felt sleep crawling onto him.
"Jean..."
The boy lifted his head, looking around. He swore he heard some voice say his name. Everyone was asleep, the rise and fall of their chests told him so. Still, he searched for whatever called to him.
A soft murmur came from Eren, Jean looked over at him. Eren was on his side, facing him. His eyebrows were creased slightly, almost in worry.
A sound that Jean could have swore was a suppressed moan came from him.
"Dreaming? About that? He can't possibly-" The boy's train of thought was interrupted by Eren breathlessly muttering his name again.
A thought crossed Jean's mind and before he could tell himself "No" he was clambering over to his bed, careful not to make any noise, he sat so that Eren was facing him.
He lifted the covers, revealing the bulge in Eren's pants. He felt his face heat up, even in the calm darkness he could stand out.
Jean's hand tentativly went down the hem of Eren's clothing, skin over skin until he took Eren's phallus in his hand, he blushed even harder realizing it was already half aroused.
Slowly, his hand moved up Eren's shaft, getting tiny moans out of the sleeping boy.
Jean knew that this was so,so wrong but he didn't care at all. Maybe it was his sleep-deprived brain or maybe it was the way Eren called out his name...so yearning...so wanting, it drove Jean's blood down south.
Eren's breathing picked up as Jean's hand moved faster, his breathing making "haaa~" noises as he exhaled. Eren's fingers curled around the sheets, holding on tightly. Eren let out a small, high pitched moan as he came, sending a hot shiver through Jean.
Despite the residue on the sheets, Jean got under them, relishing how warm it had become underneath them. He let Eren curl up to him, his head underneath Jean's chin, Jean's arm draped over his body.
With a small peck on the cheek goodnight to Eren, Jean let himself finally fall asleep.
