Erwin is a damn good cocksucker - not that Levi has any basis for comparison, but it's clearly not anywhere close to his first time. Maybe he should be embarrassed for coming so quickly, but it's actually something of a relief. Something longer and more drawn out had the higher chance of his brain catching up with him, maybe, of longer pauses letting sensations other than pleasure settle in.

It's only after he finishes shooting his load that he realizes Erwin didn't pull away, that last little squeeze as he swallows pulling a soft whine from the back of his throat. Fuck. He should find it disgusting, but the little haziness that seems to envelop both mind and body after orgasm, his brain just clocks it as hot.

For a few moments, Levi just lays there, chest rising and falling with soft, even pants until adrenaline and arousal begin to even out. Gray eyes finally crack open, staring somewhat unfocused at the ceiling. He can feel Erwin still situated between his legs, fingers looser in his hair now, and even without looking he can imagine his expression. It practically radiates off him. A heaviness settles into his limbs, relaxed, almost serene, to the point where it's almost a chore to lift his head finally just to look down to see him.

Swollen red lips and bright blue eyes and disgustingly pleased with himself.

Levi huffs, the sound more a mixture of affection and amusement than annoyance. He scruffs his hand through Erwin's hair, fingers scratching at the soft undercut at the back of his head.

"Don't have to ask how it was for you, huh. You got someone else sucking you off at the same time?"
