THIS IS SO NOT WHAT THE OP WAS LOOKING FOR. ^^; I totally forgot what I was writing in the middle of this. I was so going for like, semi-public bathroom sex because Iruka just can't hold it in, but this monstrosity happened instead AND WHY IS IT ALL IN THIS WIERD TENSE? IDEK.

When Kakashi pulls off the eyepatch, Iruka doesn't think much of it at first, apart from a slight annoyance that the movement makes Kakashi break the rhythm of his thrusts. He does that sometimes, when Iruka makes a particularly lust-ridden face - whips out the sharingan and memorises it so as to add it to the personal Iruka-porn collection in his head. And when Kakashi whispers to him that he wants to try something, Iruka just looks straight into his eyes and says that Kakashi can go right ahead. He trusts Kakashi's skill with that eye of his - or rather not of his.

The sex they have using the genjutsu is the best Iruka's ever experienced. Kakashi seems to be pulling all his most secret fantasies out of his head and making them happen, and it is the best thing to happen to Iruka ever. Ever ever ever.

His last thought before orgasming (and promptly passing out) is that the world would be a wonderful place if he could only feel like this all the time.

The next morning when Iruka wakes up with a raging hard-on, he doesn't think much of it, either. Sure, he's a little surprised to find he's so ready to go after what they'd gotten up to the previous night, but shrugs it off as his wonderful youthful virility, or something. Gai would probably know why, Kakashi muses, and is immediately smacked with a pillow for mentioning Gai - of all people! - while giving Iruka a handjob.

Iruka is almost - almost being the operative word - late for school. Konohamaru is practically swinging from the lights and when Iruka storms in he whips round guiltily from where he was poised to draw all over Iruka's desk. The permanent marker is removed from his possession and Iruka informs the class that because Konohamaru wants to draw they can all spend the day drawing - drawing graphs, that is. He then lets them know (with a hint of teacherly retribution) that the day was originally going to be spent outdoors practising kunai-throwing. The class groan with disappointment and, as one, glare at Konohamaru.

By morning break, Iruka is thanking Konohamaru in his head for giving him a reason to be sat behind his desk all day. The erection from this morning has returned and Iruka has been daydreaming vividly about his and Kakashi's exploits the previous night. Once the children leave, he stands and makes his way quickly to the teacher's bathroom, located nicely ten feet from his room. Once inside he finds a cubicle and jacks off roughly, imagining Kakashi on his knees in front of him, lips stretched around his dick, head bobbing…Iruka bites his lip and does his best to make no noise whatsoever and when he comes, it is so hard he gets slightly dizzy. Once the high has faded, however, he realises what he has done - masturbating in school! Iruka is sickened; this could get him kicked out if anyone knew.

On his way back down the corridor to the classroom he is accosted by the school's nurse, a retired medical ninja. She decides at once that Iruka is looking "peaky" and "off-colour", and tells him to go home at once! He protests, but she just bustles off to his classroom, saying that she is sure she can find someone free who can take the class and that Iruka should just get himself on home, the poor dear. Iruka just sighs and does as he is told.

The walk home is slightly surreal. Iruka feels very odd, as though tingling all over, and try as he might, he cannot stop thinking about what happened in bed the previous night. The more he tries not to dwell on it, the worse the tingling becomes, until it is centred in his groin. He decides not to walk through the streets and instead runs over the rooftops to get home, his penis uncomfortably hard in his regulation trousers. He tumbles through his bedroom window, straight onto the bed and Kakashi, who is lying naked, teasing himself with light touches. Iruka stares. His lover's whole body is flushed a delicate pink colour, apart from his cock, which is darker and dripping pre-come. Kakashi already has evidence of earlier masturbatory sessions striped across his chest and as Iruka quickly unzips his trousers and shrugs off his vest, Kakashi comes again, splattering his semen on his belly and hand. Iruka watches as he licks it off, and idly wraps a hand around his own dick, pulling and twisting his hand to increase his pleasure.

His head is still spinning, now more than ever, and as Kakashi leans closer it feels like he has been wrapped in thick cloth. He is hot, and his movements are slow - Kakashi's eyes are half lidded and he is moving oddly too, but when he grips Iruka's cock too, Iruka feels like the world moves from slow-motion to fast forward. He drags off his clothes as fast as he can and clings to Kakashi as their hands slide over each other, caressing and pinching at known hot-spots. Their teeth click together as they kiss as deeply as they can. Iruka feels like he is melting into Kakashi, but at the same time still feels very odd, as though he's not quite aware of what is happening other than the fact that it feels good.

When he next comes to his senses he is on his back, knees pressed into his chest and Kakashi pounding roughly into him. Iruka is shocked - he cannot remember how this came to happen and he cannot stop himself from moaning and jerking his dick. Suddenly Kakashi lets out a loud gasp above him and Iruka feels the familiar hot sensation in his ass - he shudders pleasurably and picks up the pace. Looking down he notices his chest is already splattered with a large amount of come in various stages of wetness, but before he can think any more his back arches and he comes again, but the high just doesn't end. Iruka pants, head spinning as he catches sight of the clock.

6:25.

Iruka freezes. He can feel Kakashi quivering, his muscles exhausted from the adrenaline and whatever else has been going on - are they drugged? - and with a great effort, pushes him away from his body. His erect dick slides out of Iruka painfully and he winces, but the pain is just what he needs. His head is clearer and he rolls Kakashi over and checks his eye to see if the pupil is blown. The uncovered sharingan spins lazily.

Fuck, Iruka thinks. Fuck and fuck. Kakashi's chest is rising and falling rapidly under his palm and Iruka kneels by the side of the bed, trying to ignore the way his penis is pressed between his stomach and the sheets. Kakashi turns his head towards him and Iruka tells him what he thinks is wrong. Slowly, Kakashi nods and sits up, attempting to figure out what went wrong in their orgasmic fun-times the previous evening. Suddenly he jerks Iruka's face towards his and Iruka stares - with great trepidation - into his lover's eyes.

Suddenly the world snaps back into place. Iruka sits up and enquires calmly of his partner something along the lines of 'what the fuck was that?' Kakashi just looks at him - with one eye - and shrugs.

THA EEEEEEEEEND.

Or is it? *dun dun duuuuuuun*

I'm sorry, OP. I ruined your amazing prompt. *cries like an emo kid*
