Eren still wasn't sure how this happened, but at this point, he really didn't care anymore.

Not many would give one shit about much of anything while straddled across the lap of the commander of the Survey Corps while he moaned like a teenager loosing their virginity- even if they were both still fully clothed. Something nagged the back of his mind about the older man admitting an attraction for himself.

Eren had admitted admiration and so much respect, and somehow that lead to their current situation in the commander's office, himself across the other's legs and grinding his ass down on the thick, hard member underneath him. And, as said, the commander wasn't shy about how the movement affected him.

Eren never would've thought the man would be so vocal, but it was hotter than a burning fire, so his own hazy brain decided to rile him further. "It's that good?" he muttered, and large hands gripped his hips more tightly- a gasp left the teen's throat when that thick cock slid deeper between his cheeks despite the barriers. "I know I'm good, but you really know how to boost an ego."

Erwin groaned again, lost to the sensations.

"S-Seriously, look at you. The th-things you must be thinking about d-doing to me." He paused only a second before daring to continue, "What are you thinking about doing to me?"

The commander's head rolled back, he was so hot and red even before provocation. Eren was leaning against the desk behind him, shifting as much of his weight as he could to Erwin's lap. "J-Just as you are," the blond finally breathed. Pull you down and push up into you… Listen to you call out in pleasure…"

"Mm… I'd do that for you."

The blond moaned again, thrusts erratic-and slowing. Even though the situation had clearly been going there, Eren couldn't quite believe he'd just made Erwin Smith come in his pants.

"Wow."

"Agreed. How rude of me," he panted. "You still haven't finished."

"I can take care of myself," the brunet offered, unbuckling his pants. "Wanna watch?"

"Painfully."

Eren lifted himself up on the desk, the heat pumping through his veins clearing any and all hesitation in unbuckling his pants. The hungry look on the commander's face wasn't hurting, either. Eren palmed himself in full view of that gaze, licking his lips and moaning as he brought himself closer and closer to the edge. The journey wouldn't be a long one, and despite being spent, Erwin's half-lidded eyes still burned. "Wanna… help?" the brunet breathed.

He'd expected a hand or two, but certainly not the commander lifting him to his knees on his own legs so he could take the younger man down his throat. Eren called out, gripping sweaty blonde strands. The journey was even shorter than he'd thought, shooting into the older man's mouth far sooner than he would've liked. Large hands eased him back to the commander's lap while he caught his breath.

The awkward started settling in. "Um… Not sure what to… um…"

Erwin started to snicker. "Would you like to come to my quarters tonight?"

"Very, very much."

"Then why don't we pick this up then, hmm?"

"I like that idea. Do you, um, want a new pair of pants?"

"It will not be a comfortable day, but I'll survive. Go now before Levi or Hanji start looking for you."

Ohh. That would be more awkward than Eren wanted to deal with ever. "All right. I'll see you tonight, Sir."

"Eren, do yourself a favor. From now on, if we're alone, don't call me 'Sir.'"

A coy smile crossed the brunet's lips. "I'll see you tonight, Erwin," he spoke purposefully, loving the lust already rekindling in the older man's eyes, and left the office before he succumbed to it again.
