The captain had always been blunt. It was in the way he spoke and in the way he acted. He didn't waste time with what wasn't necessary.
This situation is no exception either. There was always little time they could use to steal away together, so they'd quickly made the decision, dark eyes and raised brows the only given signal before Eren was swept aside to somewhere out of the public eye.
He stands the tallest, and even after all this time his hands fumble, awkwardly coming to rest on Rivaille's shoulders, who's quick to tug at brown hair and swiftly claim lips. In doing so, he shoves the other back so that his shoulders push against the cold wall of the small closet they locked themselves away in. It's sloppy and half-hearted, as they both know kissing isn't what they're here for. They'd already agreed at the very start that emotions weren't going to be involved. Or at least that's what was said. This was about something much more basic than feelings, so they could get what they wanted and leave without any further complications.
Nimble fingers wrestle with the zipper on Eren's trousers, and the shorter man drops, letting underwear drop down to pale knees. He lifts those lithe hands, and one rests on the boy's hip and the other roughly closes around his length. His expression never falters; Eren likes to think he looks scornful more from stress and fatigue rather than indifference. The brunette's head leans back against the wall, and he sighs faintly, fingers curling around dark strands of the captain's hair as his lips pressed lightly to the head of his cock.
The first time they'd met like this it'd been a much more unorganised event. He had fumbled horribly, trembling and finishing far too quickly. But what had Rivaille expected from him? It seemed so long as Jaeger was willing to repay the favour, he didn't mind. And back then he was so much more conscious, so much more aware of how unspeakable it was without even considering their ages and positions. But those were now unimportant things, and worry had faded away and left a much more primal instinct. Now it was just the seemingly easy way to break away from reality for a few minutes, and ease their shoulders of a little weight. If it hadn't been Eren, it would have been someone else. It was just more convenient this way, as there would be less questions about their disappearances together if he was supposed to be monitoring him.
Lips part and Eren jerks a little, brows furrowed. He wants so desperately to shift his hips to meet the other's mouth, but he's pinned back with strong hands. Rivaille's tongue works languidly, brushing over the tip and shaft, and he's urged on by the little quivers in the boy's breath as he bites his lip. His finish is almost silent, the only noise being a breathy grunt. He's lost his fantasies and ideas of perfect, mind-blowing orgasms by now, and is happy to settle with just this little high.
Rivaille pulls away, and it splatters onto the floor before he wipes the corner of his lips with his sleeve. He can ignore the mess for now. He stands at his full unimpressive height again, having brushed himself off briefly, he meets eyes with a flustered Eren while undoing his own belt.
"Captain, I-"
"Rivaille."
Now wasn't the time for those formalities. After all, now he'd rather they just be two men rather than a soldier and a Lance Corporal. Whatever it was he'd planned to say had been silenced with a meek nod, and it was probably better that way. He swallows dryly, gazing at the blank expression pasted on the elder's face. He's realised there is nothing to say and nothing to do besides fill his side of the deal. That was just how their hushed agreement was. With no other words exchanged, Eren kneels, tugging clothing aside and taking Rivaille in his mouth.
