With a forceful flip, Iruka swapped his arms around Kakashi's sweaty torso and sank his teeth into his shoulder blade. The action only excited Kakashi more, and as his thrusting rhythm heightened, the springs in the mattress screeched, protested loudly against him. A series of moans escaped Iruka's swollen lips and were muffled by Kakashi's skin.

"My love, don't cover your mouth, I like it when you're wild and loud," Kakashi teased and pulled Iruka's head back, revealing a face that was flushed with pleasure. Before Iruka could protest, he pressed his lips against Iruka's and pushed him onto the mattress. Iruka gasped at the deepened movement and clutched at the sheets.

"You… cheating… bastard…," Iruka's mind was probably half gone when he blurted out these words, but they were all Kakashi needed.

Ouch.

Kakashi's hiss echoed in the steamy shower cubicle, as he ran his fingertips over the bleeding bite mark on his shoulder. Now that he realized how deep the wound had been, the pain grew consciously and began to throb. But it did little to change the smug grin that was plastered on his face.

Iruka had proven to be a challenging one, Kakashi admitted in hindsight. Most men and women would eagerly fall into his arms by the mere mentioning of his name. But he knew it would take more to find his way into the guarded chuunin, who had dealt with love his whole life with the defense mechanism of a hedgehog. The hard work paid off, and they were an official couple.

But Iruka was not a man who liked to share his feelings, and sex aside, Kakashi had not seen any signs of amorous demonstration from Iruka's side. No whispers of love, no passionate gazes. No fiery jealousy over Kakashi's past antics.
Iruka was clearly not in love. The conquest wasn't over.

Then Kakashi met her. A woman he had spent some lonely nights with. Just for old times' sake, she offered. Iruka was working late that night, so he accepted. And that was when a brilliant idea came into mind.

Kakashi staged the scenario carefully. Iruka would walk into the woman in the street on his way home. He would smell the shampoo in her hair, a unique blend Kakashi brought back from outside the village. Kakashi left a claw mark on his shoulder blade. Everything was perfect. He just had to wait for the main scene to be acted out.

Kakashi chuckled again, as he walked out of the shower and dried himself. The rest was too easy. Was the bite mark Iruka's idea of revenge? It was endearing, and so very Iruka. He traced the wound once again lovingly before returning to bed.

Iruka was still awake. He looked a little dazed out, but his gaze soon fell on Kakashi's shoulder. Kakashi grinned innocently and pushed his way under the sheets. He had expected a strong punch from the chuunin's fist of death, but what came instead was an unexpected hand wrapped firmly around his cock.

"What? Iruka-sensei? You can't wait for round two already?" his smile turned into a leer. This is not bad, not bad at all.

Still savoring the sweet sensation of the grip on his pleasure zone, Iruka's whispered words before drifting to sleep stopped him cold:

"Next time, it won't be your shoulder."
