Haruka and Sousuke endure a physical relationship

Haruka Nanase was for a better word a forbidden temptation. Rin had confided in him about his passionate feelings for the ravenette and the butterfly swimmer had specifically told himself that Haru was off limits. Sousuke wouldn't do that to Rin, the red head was his best friend.

The only problem was Sousuke broke the silent promise. But when Haruka caught him changing after swim practice, jammers around his ankles Sousuke couldn't help but notice the furious blush on Haru's cheeks and that his ocean blue eyes were concentrating on the organ between his legs. He had wanted to resist, fuck, he did, but Haru was not one to take no for an answer and honestly, Sousuke didn't want to say no either. So, yes Sousuke had sex with the free style swimmer, he followed the teen home, bending him over his table and thrusting into him until they were both spent of energy. Sousuke would have liked to say it only happened the once, unfortunately, the temptation was far too strong for Sousuke, his mental reality fixated on his penis. Their first sexual encounter suddenly became a weekly meet up with the butterfly swimmer executing rather elaborate lies to tell Rin that had Sousuke feeling less guilty as the lies went on. He didn't know what he was doing, he didn't particularly harbour any feelings for the ravenette and he was certain Haru didn't either but the way their bodies came together every time just felt right. The lewd noises that would always escape Haru's throat caused Sousuke to quickly become addicted, almost slamming him against the wall as soon as the boy opened the door.

"No one can know about this," Sousuke grunted out as he pushed himself deeper into the moaning ravenette who was clutching at the sheets.

"I know, just shut up and move."

Sousuke's eye twitched in annoyance, jerking Haru's head back by his hair causing the free style swimmer to gasp breathlessly. An almost pornographic groan escaped Haruka as Sousuke sucked on his neck provoking the teal eyed male to thrust harder in hunger.

"Is that a hickey Haru-chan?" Nagisa exclaimed as soon as he saw friend's approach, his eyes instantly seeking the tip of the bitten bruise hiding behind the collar of the boys shirt. Haruka was quick to cover his neck with his hand, a slight blush covering his cheeks as he diverted his eye. "Haru-chan! Do you have a girlfriend?!"

"No."

"A boyfriend then?" Nagisa pulled at the boy's arms wanting to inspect the blemish on the free style swimmers flawless skin closer.

"No."

"Aww, Haru-chan you can tell me." Nagisa pouted fluttering his eye lashes, pleading at the unimpressed ravenette.

"It's just a bruise." Haruka's fingers tightened a little against his neck, digging into the sensitive skin, almost revelling once again in the touch that Sousuke had provided. Nagisa eyed the boy suspiciously as Haru turned away, arm falling back to his side, the 'hickey' no longer in sight but that small flick of a smile was anything but subtle.

"Nice love bite," Sousuke commented letting his tongue run over the bruised skin. "Guess I got carried away."

"You have no-" Haruka jolted moaning as Sousuke hit his prostate, gripping the sheets with white knuckled strength. He let out a few steady breaths before he continued. "-idea what I went through today."

"I can only imagine." Sousuke snorted smugly, gasping involuntarily as Haruka yanked roughly at his hair. "Oi!"

Sousuke retaliated by thrusting deep, a mistake on his part as Haruka yelped, pulling even harder forcing the butterfly swimmer to whip his head back. Sousuke winced ever so slightly but soon the stinging sensation faded and the breathless look on Haru's face had him gripping the boy's waist harshly as he continued his assault with new vigour. Thankfully for Sousuke, the harsh momentum had Haruka removing his hands from his brown locks butinstead he raked his finger nails up the man's back as he came hard.

Sousuke hadn't realised Haruka had actually left significant marks on his back until the next day at swim practice. Casually walking out the locker room listening to Rin prattle on, oblivious to the stunned gazes he received as he strode passed.

"Yo, Sousuke!" A boy from behind him called, "Nice scratch marks, must have given it to them good."

Sousuke turned to the swimmer that spoke, raising a brow in confusion before his eyes flew open in horror as the boy motioned to his back.

"Shit." Sousuke muttered under his breath, "Damn it."

The teal eyed teen furrowed his brow as he attempted to feel the tip of the abrasions, he was so going to get Haruka back for this.

When the Iwatobi team finally arrived and Rin had run over hugging Haruka tightly, the ravenette peeked over the red heads shoulder, letting out a small noise of amusement and horror when he caught the sight of the raw red claw marks raking up Sousuke's back. The glare he received from the butterfly swimmer when he turned around had Haruka smirking ever so slightly. Sousuke was pissed which made Haruka all the more pleased with his actions.

That afternoon Haruka was fucked with such raw aggression he was unable to stand after for several hours, his body littered with small bruises where Sousuke had bitten with both lust and revenge. All agreements that they settled on flew out the window; kissing had been on the top of what they shouldn't partake in, Haru stating it was too intimate for what they were doing. But as soon as Sousuke had Haruka through the door they met halfway, teeth and tongues clashing together in a battle for dominance. Afterward, as Sousuke slumped down beside the ravenette he had twisted onto his side and flung his arm over Haru's waist. Intimate contact was another detail that was dismissed in this instance and Haruka shuffled closer splaying his hands over Sousuke's chest. The free style swimmer gazed into the teal eyes leaning into the man's touch as he caressed his jaw, noting the emotion that was strictly prohibited. Sousuke leant in, pressing his lips against Haru's who eagerly kissed back, sighing as Sousuke's tongue ran over his bottom lip.

"I love you." Haruka unconsciously announced after they broke apart, eyes widening dramatically realising what he just said and diverted his eyes when Sousuke froze rigid. "Sorry, I didn't mean to say that."

Sousuke mentally was no longer with the ravenette, he was slumped on Rin's bunk listening to the red head talk about Haruka. The way the teen's eyes lit up as he talked, the way he would let out a small internal squeal when Haru would appear at swim practice. Fuck, what have I done? Sousuke blinked as he felt movement beside him. Haruka was untangling himself from Sousuke's limbs and for some reason, the teal eyed man refused to let him go. Did he regret having sex with Haru? The way they went around it, yes but initially no. They both wanted it, the only reason they kept it a secret was for Rin's sake, Sousuke clearly remembered Haruka stating that he didn't care if Rin knew or not but Sousuke knew better. The butterfly swimmer could see the look of betrayal already, his insides twisting into knots, gulping as he pulled Haruka's to his chest.

Sousuke was selfish, terribly so but when he really thought about it, what he and Haruka had been doing, he found his heart warming. Rin wasn't the only one infatuated with the ravenette and that caused Sousuke to suddenly dismiss the red head and focus on himself.

"Sousuke?" Haruka whispered cautiously, "Are you okay?"

"I love you too."
