Anger Relief

Pairing: IwaOi

"Can you fucking believe it?!" Oikawa looked up at Iwaizumi who just entered the apartment, wildly kicked off his shoes and stomped into the room.

"Hi Iwa-chan. Angry?" he asked calmly, and he smiled when Iwaizumi threw the bag with their dinner at him. He caught it and peeked inside.

"Those idiots messed up my order! But they refused to take it back and switch, neither did I get a refund, are you fucking kidding me?!" The anger and frustration burst out of him as he walked around the room.

"It's okay, I like cheeseburgers too," Oikawa said when he looked at the food Iwaizumi had just brought home.

"Which isn't the point! This is the last time I'm getting take out there, first they took ages to finish, then…" Oikawa shrugged and took a quick bite, only half listening to his boyfriend's angry rant.

"Won't you eat?" he asked when Iwaizumi had to pause to catch his breath.

"No! I just can't stand those people. I'll go write a bad review now," Iwaizumi stomped towards the couch and angrily sat down next to Oikawa. He took out his phone and roughly pushed the buttons, seemingly determined to rage all he wanted about the bad service.

"You're too damn cute," Oikawa said, smiling as he ate Iwaizumi's share too.

"Cute? Oh so you like me when I'm angry?!" Oikawa knew Iwaizumi didn't mean to direct his anger at him. In fact, he was enjoying every second of this. Angry Iwaizumi was just too cute and sexy for words.

"Yes I do," Oikawa said, stuffing the second cheeseburger into his mouth with unbelievable speed. He reached back into the bag to pick out the fries and flashed his lover a sweet smile.

"What?" he asked innocently.

"I am being frustrated as fuck here and you think I'm cute?" Iwaizumi asked, unaware of how adorable he looked with his rosy cheeks and his brows furrowed like that.

"I can't help it, sorry. Shall I make it up to you? You can release your anger on me, I'll be the perfect anger relief for you," Oikawa said, dropping the bag again and lying back down onto the couch with his arms tucked behind his head. His legs spread on either side of Iwaizumi and he grinned teasingly.

"What will it be? Curse at me all you want, or even better. Anger sex? That would be hot," Oikawa said, and he hummed happily and moved his head from side to side. Iwaizumi looked at him in disbelief but then snorted, put away his phone and climbed on top of Oikawa.

"Sure, if you're offering," Iwaizumi said, straddling Oikawa's waist.

"Hoooh? Anger sex it is? I am sooo exci- oohahaha no wait!" Oikawa quickly moved his arms back down when Iwaizumi clawed at his sides, and he looked up at him with big eyes.

"What are you doing?" he asked as Iwaizumi took a quick pause, his fingers still lingering on Oikawa's sides, which Oikawa tried to protect by bending his arms and pushing his elbows against his sides.

"Using you for my anger relief," Iwaizumi said, and a tiny smirk appeared on his face. Oh shit. Oikawa knew he was screwed and it was his very own fault, so he gathered all the breath he could and soon exploded in a hysterical fit at the merciless tickling of his sides and ribs.

Iwaizumi didn't say a word. He just watched him with a cold smirk on his face while he vented his anger out by tickling Oikawa mercilessly.

"AAhahaha Iwa-chaahahan!" Oikawa knew he had offered it by himself, but he hadn't thought Iwaizumi would've gone as far as tickling him. He bucked and thrashed under him, his arms helplessly shooting all over to protect his tingling body from Iwaizumi's quick hands, but to no avail.

Iwaizumi clawed at his sides and ribs, scribbled his fingers all over his tummy and shoved his hands under his arms so he could scratch at his hysterical boyfriend's sensitive armpits.

"I'm dyyyihihing naaahaha Iwaaaa-chan!" Hearing his lover's bright and adorable laughter and giggles, the frown on Iwaizumi's face slowly started to disappear.

"OOOhoho p-pleheease!" Iwaizumi's cold hands had moved under Oikawa's shirt, his fingers crawling all over the bare skin of his stomach and sides.

"Ihihiii- Iwa-chaaan!" Oikawa whined, and he gasped a little when one of Iwaizumi's fingers slipped into his belly button.

"HMph- don't! Meheheercy!" The cold smirk on Iwaizumi's face had now made place for a loving smile, and even though Oikawa's vision was blurry from the tears in his eyes, he couldn't help but feel happy when he noticed the change of Iwaizumi's expression. It was really helping… Still, he wasn't sure how much more he could take until–

"I'LL PEEHehehe! Iwa-ahaha Iwa-chan!" Iwaizumi finally stopped the ruthless tickle attack of his boyfriend's torso and he smiled.

"I'm sorry. And thanks, that really helped," he said, winking at him, and Oikawa blushed.

"It d-did?" he asked, breathing heavily and nervously pulling down his shirt to cover his tummy back up, but Iwaizumi stopped him and shoved his shirt back up all the way over his chest.

"It did," he whispered, and he leaned in and kissed Oikawa passionately. Oikawa grinded against him and kissed him back, his arms moving up and wrapping around Iwaizumi's neck. Now this was more like the thing he had imagined when he seduced his boyfriend to help him with his anger relief.

"NOohoho meanieee- hehehe!" Hysterical giggles burst out of his mouth again when Iwaizumi returned to scitter his fingers all over his bare chest and tummy, shattering Oikawa's expectations of anger sex- for now.

"You're too damn cute, Ticklykawa," Iwaizumi said, and Oikawa blushed again and surrendered to the sweet tickle attack.

"Hehehee stoohoooop!" The angry tickling had made place for sweet and loving tickles, and even though Oikawa's body was protesting with all its might and he was screaming bloody murder, he was enjoying this even more than seeing Iwaizumi and his adorable anger.
