3: Enemies With Benefits

Warning for some slight internalized homophobia

Dean considered himself to be a fairly reasonable and tolerant person. He let people mind their own business and didn't try to police others. He never judged people's choices and he mostly kept to himself.

There was, however, one exception to his tolerance, and that exception was one Seamus Finnigan.

He couldn't remember why or exactly how their animosity began, but what he did know was that Seamus was a crude, arrogant, and purely aggravating person to be around. He got along with his other dormmates just fine, but when it came to Seamus, Dean had no patience.

Dean would be happy to ignore Seamus for the rest of his Hogwarts years, then graduate and pretend he'd never had to deal with having the urchin in his life, but the issue there was that Seamus was really attractive.

Baby blue eyes, sandy hair that fell perfectly, a spattering of freckles across the bridge of his nose - he was a perfect subject, and Dean, being an artist, naturally had the urge to capture beautiful images. As such, Dean has a ton of secret drawings of Seamus hidden among his things. A sketch of Seamus post-explosion with smoking eyebrows, a watercolor depicting Seamus sitting in a pool of sunlight, Seamus laughing by -

"What's yer problem?" Seamus snapped from where he was sitting at a table in the common room, his textbooks spread out in front of him.

Dean looked back down at his Charms book, realizing that he'd been staring. "Nothing."

Seamus snorted and returned to studying, a scowl on his beautiful face.

All of the fifth year Gryffindors (minus Neville, who'd locked himself in the greenhouses all weekend) were gathered in the common room studying for their O.W.L.s, which would begin tomorrow. Harry, Ron, and Hermione were quizzing each other in a corner, but it had mostly dissolved into Hermione frantically lecturing the boys and fretting about how she should've studied more. Parvati and Lavender had fallen asleep curled around each other in an armchair, with a Divination book starting to slip out of Parvati's hand. Seamus occupied a table on the far side of the common room, and Dean was on a bench on the other side, although he wasn't so much studying as unconsciously sketching Seamus on the pages of his Charms book.

THUD!

The heavy Divination book finally fell out of Parvati's hand, startling everyone in the common room. The girlfriends almost fell out of the armchair in fright, Seamus yelped, Hermione cut off her explanation of the complicated nature of dragon blood, Harry and Ron stopped dozing off, and Dean's hand jerked so there was now a long dark line across his page.

"What time's…?" Lavender mumbled as Parvati gently maneuvered the two of them out of the chair and picked up the book.

Ron glanced at his watch. "Almost two."

"We're going to bed," Parvati said firmly, putting an arm around Lavender's waist and guiding her toward the girls' staircase. "See you lot in the morning."

"I'm going to bed as well," Harry said, picking his books up.

"But we haven't even covered - " Hermione started shrilly.

"Come on, 'Mione, you've been studying since first year. You'll be great," Ron said around a yawn. "Me 'n Harry are already a lost cause, but thanks for the help."

Hermione sighed, her brows knit with anxiety, but then she started to help her friends pack up their books and notes. As they turned to head for the staircases, they eyed Seamus and Dean warily.

"You two coming up?" Ron asked.

Dean and Seamus made eye contact across the common room. The air was tense and silent as they watched each other.

"I'll stay here a bit longer," Dean replied. "Just another chapter to go over."

Harry nodded and turned to Seamus, who narrowed his eyes for a moment and then nodded curtly before bending back over his books.

"Right, well, night," Harry said.

The trio turned and went up their respective staircases, their footsteps receding until silence descended with the clicks of doors closing at the top of the stairs. Dean swallowed thickly, acutely aware of Seamus' presence at the other side of the common room. He was surprised Seamus elected to stay in the common room; they were almost never alone together.

His chest started to feel tight, and he started to get mad at himself. He wasn't even sure why he stayed: he'd been over all his Charms material, there was nothing left to study. He looked at the small sketch of Seamus' he'd been doing, and sighed inwardly. Recently, he hadn't been able to get the Irishman out of his head. And it wasn't because Seamus was annoying him or anything. Rather, Dean just had images of him stuck in his head, like the way Seamus always looked surprised when something blew up, or the sound of his laughter. It was becoming a problem.

Dean had accepted the fact that he was attracted to both guys and girls a while back, but what he couldn't get used to was the fact that he was pretty sure he was attracted to Seamus Finnigan.

Tap, tap, tap, tap

Dean looked up and saw Seamus tapping his quill on the table and chewing his lip with a frustrated expression. He waited for the tapping to stop, but it continued, the only sound in the otherwise silent common room.

He cleared his throat and Seamus looked up. "Could you perhaps not?" he asked.

Seamus rolled his eyes, but his hand stilled and the tapping stopped. Dean closed his Charms book and began to shuffle through his notes to look for something else to study.

Tap, tap, tap, tap

"Really?" Dean asked, frowning deeply.

"Shove off, Thomas," Seamus snapped.

"You got a problem, mate?"

Seamus sighed in aggravation. "Yeah, actually, I do," he said, slamming his quill down on the table hard enough to make his ink well jump as he rose from the floor. "It's ye."

Dean tensed as Seamus approached, his stride strong and purposeful. Seamus may be almost a foot shorter than Dean, but he could be intimidating when he wanted to be. None of their tiffs had ever come to blows before, but the look on Seamus' face as he came over made him want to reach for his wand.

Seamus was a few feet from him now. Dean prepared himself for all sorts of things. Seamus could attack him physically, but Dean was fairly good at fighting, and he had the size advantage. Seamus might jinx him, but Dean saw Seamus' wand lying on the table, so he was safe from that. Seamus could berate him for something Dean might've done to offend him, but Dean couldn't think of -

Seamus grabbed Dean's face and kissed him full on the mouth.

Well. That was unexpected, but not entirely unwelcome.

Dean surged up to return the kiss, one arm wrapping around Seamus' waist and the other around his back. With Dean sitting and Seamus standing, the angle was different than in all his imaginations, but the sensation was even better.

"Wait, what's - " Dean said, pulling back as he tried to make sense of this.

"Shut up," Seamus replied, going back in.

He licked along Dean's lower lip and Dean opened for him. Seamus took control instantly. It was all Dean could do to try to remember to breathe.

"But you hate me," Dean said dumbly.

"Yes. No," Seamus replied, looking cross.

Dean blinked. "What?"

Seamus rolled his eyes and straddled Dean's lap, rubbing their hips together, causing Dean to groan aloud and put a hand on the small of Seamus' back.

"Shh," Seamus said, kissing Dean again. "Don't want ter wake everyone up."

Dean took the initiative this time and leaned in to kiss Seamus, knotting the fingers of his other hand in the dirty blonde hair. Seamus moaned lightly, which sent heart surging down to Dean's pants. Dean sucked on Seamus' lower lip before pulling away again.

"What's happening here?" he asked, trying to get himself to focus despite Seamus' big red lips and blown pupils.

"Well, Dean, when two blokes - " Seamus started.

"Oh piss off," Dean said with a slight growl, grabbing Seamus and pulling him down to the bench so Dean was over him. "Why the sudden snogging? You haven't been able to look at me for more than five seconds since first year."

"Well at first it's cause I thought ye were stuck up," Seamus answered. "Then it's cause ye're so bloody attractive."

Dean raised his eyebrows. "Really?"

"Shut up," Seamus snapped, using his legs to bring Dean's hips against his again. They both groaned this time.

"So what was the problem?" Dean asked, leaning on his elbows so their faces were closer.

Seamus blushed slightly. "Ye're a bloke. I thought it was wrong. I hated ye for making me attracted to ye."

"Then what changed?" Dean asked, lightly kissing Seamus' neck, eliciting a shiver.

"Parvati and Lavender got together," Seamus replied. "Nobody cared about two girls bein' a couple, so I figured…"

Dean laughed against Seamus' collarbone. "Are we a couple now?"

"Don't get ahead of yerself," Seamus said, grabbing Dean's face so he could look at him. "Ye still piss me off."

Dean laughed again and met Seamus' lips. He realized that this was really the first conversation he'd ever had with Seamus. And as they kissed, he started to wonder what exactly it was that had made him dislike Seamus in the first place.

"What about ye?" Seamus asked. "Ye hated me, too. Why so enthusiastic?"

"Same problem: you're too attractive," Dean replied, causing Seamus to grin. "But you still annoy me. Although, if our interactions continue being like this, I might just warm up to you."

Seamus rolled his eyes and pulled Dean down again.

HPHPHP

"Ten galleons, Longbottom," Parvati said as she and Lavender walked up to him. "Each."

"What are you talking about?" he asked.

"Didn't you see the hickeys on Dean's neck?" Lavender asked, giggling.

Neville's jaw dropped in disbelief. "No, really?"

Parvati grinned wickedly. "Really."

Neville grumbled to himself as he trudged up the stairs to get his money. More money would pass hands the next day when Dean and Seamus started to hold hands in public.

HPHPHP

"Ye're so needy," Seamus complained a couple months later, rubbing his thumbs into Dean's back.

"Shut up, Finnigan," Dean said with a laugh, grabbing Seamus' hands and pulling them forward so Seamus was flush against his back.

"I still hate ye," Seamus whined.

"Sure, sure," Dean replied, turning his head and meeting Seamus' lips.
