It is horrifically embarrassing. Humiliating, even, but given the amount of Icha Icha he's consumed, that's just makes it more embarrassing. Embarrassing that he can now identify he has a humiliation kink, embarrassing he got hard in the middle of the Hokage's address for the chuunin exams, and most embarrassing that it was Umino Iruka who did it to him.
Well, uh. At least nobody else noticed, he hoped. Especially since he fled immediately after the meeting, face incomprehensibly red under his mask, overcome with the need to touch himself, immediately.
Something about that angry, barely repressed fury being focused on him and only on him, especially coming from someone so mild, so kind as Umino Iruka. His thoughts so consumed, Kakashi can barely get two fingers in himself and his free hand on his dick before he's coming in the entryway of his apartment.
It's fine. He'll never think about this again.
-
He doesn't think about it for at least a few days, not until the second part of the exams is over and he can sleep in his own bed one last time before whisking Sasuke away for training. There's so much running through his mind, about Naruto and Sasuke, about Orochimaru, about what will happen in a month. His brain feels like static, like panic, and as Kakashi tries to think of anything but the near future which surely contains an international incident—
He remembers Iruka. The look on his face, furious, directed at Kakashi. Fuck.
Well. He is going to be stuck supervising one of his students for the next month, he won't have a chance for this—
The tube of lube he keeps hidden under his mattress has been untouched for a while but now Kakashi has a liberal amount of it helping him finger himself open, his own sleep shirt pulled up so he can bite on it and hopefully not give his neighbours reason to believe he's sexually into Umino Iruka even though he's very into Umino Iruka, especially when the man looks at him in disappointment, anger. Raises his voice, criticises him. Kakashi can't help but fantasise about what could be, about Iruka fucking him hard and raw, with none of that regular kindness in his eyes.
He comes with a strangled noise, then keeps going until he orgasms again, almost painfully, then a third time, dry.
Maybe he’s also a masochist, he considers, once he can feel his toes again and his temperature is nearing normal, though his muscles are still shuddering from the overstimulation. Maybe it’s just the thought of Iruka being the one to do it.

It's after the exams and the invasion is memory—recent, still, but memory—that Iruka corners him again. This time it’s not about the chuunin exams, at least directly, but about Sasuke, and Kakashi can’t help but admit that Iruka is definitely right on chewing him about about that.
But. He’d be right to do that if they weren’t in an alleyway behind the grocery store and Kakashi wasn’t already red-faced and weak-kneed at how close Iruka is, how dark his eyes are and firmly disapproving his voice is. He’s an absolute fucking embarrassment and drowning in his absolute fucking embarrassment but, wow, Iruka is hot when he’s angry.
Kakashi is way too overcome for this, but body-flickering away while Iruka is still mad would just make things worse in the long run. He frankly wishes he could melt on the spot and apparently that shows because Iruka abruptly breaks off talking about how Sasuke should be seen by Jiriaya, eyebrows crinkling in concern.
"Wait, you," Iruka steps closer and Kakashi can't even hold back a painfully aroused shudder, "are you okay, Kakashi?"
The sudden switch, the anger melting into genuine concern and the worry and softness suddenly warming Iruka's gaze, it's too much. He slaps a hand over his mouth as he actually cums in his pants.
Oh fuck. He’s never living this down, if he even gets out of it. And fuck, even though he just came he’s already semi-hard again, and Iruka is getting increasingly closer. He actually reaches out to touch Kakashi’s face, his own face so close because he has to lean up, into Kakashi, while Kakashi desperately tries to lean away, get some sort of space.
“Why are you so hot?” Iruka mutters, before half-falling into Kakashi since he’s leaning so far trying to reach his face and, oh no, oh no.
Both of them freeze. Kakashi would like to die, thank you, as quickly as possible, because Iruka is definitely feeling how hard he is and how the fuck is he going to explain himself and. Kakashi would like to die as quickly as possible.
Though, really, it just makes him harder.
-
It’s even better than any of Kakashi’s fantasising, especially when Iruka is holding his hips so tightly there’s going to be bruises and has left bites and hickeys from his jaw down, anywhere that will be covered by his uniform.
Oh, he’s never recovering from this.
-
And he is a masochist.
-
Kakashi literally cannot get out of bed the next morning. Iruka is fine, which is, frankly, cruel, but he also drops a kiss on Kakashi’s forehead before leaving for work at the school, and that cancels any cruelty out. When he finally is able to slide out of bed and go take a bath because there's no way he can stand for as long as shower, the marks on his skin send him just as red as Iruka being mean to him.
He’s too far gone.
Iruka’s going to have to take responsibility.
