Severus was packing up the last of his parchment after detention. Professor Flitwick had already cleared out and he was debating whether it would be better for him to leave after or before Black to avoid being hexed.
“Can I kiss you?”
Severus looked up, for the first time in perhaps ever, Sirius’ voice wasn’t mocking or without a teasing edge to it when speaking to him. He stood there with a flirty smile and his body language seemed relaxed. It was close to curfew so they really shouldn’t be hanging around anyways.
Severus wondered what brought this on, had Sirius looked inside his mind and seen the fantasies he harbors for various attractive well built quidditch players?
Had he somehow figured out Severus was gay?
Severus absolutely loathed the Marauders with all he had, but even he wouldn’t deny that he’d fantasized about having his prick in Sirius’ mouth or perhaps Sirius’ prick up his own arse.
Sirius stood there smiling, leaning towards him earnestly and raised his eyebrows waiting for his response.
“I’m not really into men who are as annoying as you”
“But you are into men?” Sirius looked excited at the prospect. His flirty smile turned into a smirk.
Severus narrowed his eyes and refused to answer.
“Why would you want to kiss me anyways? We hate each other”
Sirius shrugged
“Maybe. But I also find you fascinating and your intelligence is starting to grow on me.”
“So you’re hoping that by kissing me a few times maybe I’ll start doing your homework? Severus sneered at him “go ask Lupin or Evans. I’m not interested in doing anyone’s work but my own”
“But you are interested in kissing me, right?”
“Shut up,” Severus growled. But then found himself crashing his lips to the other boy’s. Mainly to shut him up, he couldn’t stand to hear Black’s voice anymore, not when it sounded so sincere. As his thoughts seemed to melt away he found that Black’s tongue was in his mouth as if caressing his own tongue. Severus moved his hands up into Sirius’ curls. He pulled gently. Sirius moaned into the kiss and grabbed Severus’ arse and squeezed.
Sirius slowly pulled back and smiled at Severus, Severus flushed and attached his mouth to Sirius’ smooth unblemished neck. Determined to devour it. Sirius actually mewled under his touch and then suddenly moved back.
He gently kissed his nose and forehead and adjusted himself. They were both hard and panting.
‘How long have we been making out?’ Severus wondered to himself.
As they both walked away from each other Severus noted that he’d need to take a cold shower tonight and felt annoyed. Although the fact that Sirius would probably need one too did bring a small smile to his face.

A few weeks later they both somehow were on their own going to the library. Sirius was probably going to meet his trouble making asshole friends and Severus was on his way to study with Rosier.
Sirius suddenly threw his arms around his neck and kissed him with all he had, he found himself unable to resist.
“Meet me in the abandoned potions classroom at midnight,” Sirius whispered to him a little out of breath.
He pushed his forehead into Severus’ as Severus gave him a shaky nod in return.
That night as they pawed at each other and began sharing small smiles and giggles between kisses, Severus knew he wanted more. He wanted to demand something from Sirius, but he had no idea what or how to start. On top of being less experienced than Sirius obviously was he was so unused to asking for anything from anyone.
Severus just decided to follow Sirius’ lead and closed his hands around Sirius’ ass just as he had grabbed Severus’ last time. He pushed his groin into his and squeezed his asscheeks. Sirius gave a small shout and began to rut himself against Severus. He absolutely lost it and if Severus hadn’t been so lost himself he would’ve felt smug about rendering this jackass mindless in his desire.
---
They somehow ran into each other again on the same day the following week and decided to move their little tryst into the prefect’s bathroom. Sirius had probably gotten the password from Lupin. Severus didn’t really care all he could think about was having Sirius’ lips back on his neck and his body.
As Sirius played with various taps and put some sort of salts into the bath Severus stood to the side and watched. He was both excited and nervous. Severus watched him undress, Sirius turned towards Severus as he lowered himself into the steamy water, his cheeks flushed. He held out his hands in silent invitation for Severus to join him and Severus almost jumped into his arms fully clothed.
They didn’t exchange too many words as their hands began to travel over each other’s bodies. In some ways Severus felt impatient but Sirius seemed content to take it slow and look at and touch every single inch of Severus’ body. Severus was just amazed that he was able to lay his hands on someone like Sirius and for Sirius’ body to react the way it did. Sirius seemed to want Severus just as badly.
Severus almost came untouched when Sirius took one of his nipples into his mouth.
Neither of them took very long to cum once they gripped each other. It was surreal to have his first time be with this beautiful boy, this man he had such complicated feelings of hate filled lust for.
“I wanted to last longer but you’re killing me Sev, you’re incredibly sexy…” Sirius panted out as he laid his body against Severus’
Severus wanted to turn to him and tell him how desirable he found him, hell how desirable the entire student body found Sirius. How much he admired his outgoing nature, his quidditch skills, how funny he thought he could be if he wasn’t such an asshole. He wanted to tell Sirius that he was one of the most beautiful people he’d ever laid his eyes on. But instead he looked him in the eyes and kissed him deeply. Sirius melted into his body and Severus loved every second of it.
“I need to get to the library, but Let's meet up in the room of requirement this weekend”
“You really are a genius, Snape.”
---
That weekend they missed breakfast.
“You know I’ve never missed breakfast before?”
Sirius didn’t let go of Severus’ waist as he moved back slightly to look at him and smile.
“Not even for quidditch?”
“I will make it down to the kitchens if I have to, but I’m a growing boy…I need my meals”
“Well what are we going to do Black?”
“We could have one of the elves bring us breakfast in here”
Severus raised his eyebrows
“That’s possible?”
“Sure, especially if one of your family elves is here with you at Hogwarts”
“Ugh, all you pureblood rich kids suck”
“Suck you say?”
True to his words, Sirius began kissing down Severus’ body and a wave of heat seemed to come over him. Sirius Black’s pink pouty lips closed around Severus’ prick and all coherent thought flew out his head. As Severus came down his throat all he could think about was getting Sirius’ heavy erection into his mouth. Severus was, apparently, really good at blowing him because Sirius’ reactions were beyond anything he’d ever seen or heard before. Severus loved the feeling of power he felt despite being the one on his knees bent over Sirius’ body.
They didn’t eat until after lunch, and neither of them minded.
---
They continued on like this for the rest of the year, Severus’ mood improved and his grades did too. The same happened to Sirius. It seemed like spending all his extra time doing Severus instead of planning pranks was keeping him out of detention long enough to be a worthwhile student for once.
This is just a fling Severus told himself over and over. Who cares about Sirius’ grades, or that he wasn’t in detention. All that mattered was he was getting off and the marauder’s had slightly backed off of him.
Just. A. Fling. He'd repeat to himself after every tryst in the prefect's bathroom.
No feelings involved he'd remind himself every time he'd fall asleep in Sirius' arms in the room of requirement.
He did his best to not focus on the fact that his thoughts were filled with Sirius' from the moment he woke up to the moment he fell asleep. He thought of how beautiful he looked coming undone under him. He thought about things to share with him over the course of the day. As he made plans for after Hogwarts he'd somehow always think of what Sirius would want or think and then try to come up with alternatives that would suit both of them. Then he would promptly ignore those thoughts and continue on with what he needed to do.
At the end of the year after the 6th year party Sirius cornered Severus in the hallway.
“Dance with me?”
“I don’t dance”
“Why not? You move so gracefully when you cast spells, I’m sure you’re a perfectly decent dancer”
“It’s not that I can’t, it’s that I don’t”
Sirius smirked at him.
“I really want to kiss you right now.”
Severus was surprised by his own honesty in that moment but he could've kept it back if he tried.
“What’s stopping you?”
“Oh I don’t know anyone could come around the corner from the party at any moment and see us snogging in this hallway”
“Would that be so bad, Snape?”
Severus kissed him. The most gentle chase kiss he could possibly muster at this moment. He laid one of his hands against Sirius’ warm cheek and put another hand on Sirius’ waist. Sirius gently kissed him back, both hands on his shoulders. As if he was trying to state his feelings with his touch instead of his words.
“If we keep kissing like that Severus we’ll definitely fall in love”
Severus suddenly felt panic. Love? There were no feelings between them. This was a fling only. If it turned into anything more it could only end badly for one of them. Probably Severus.
For the last 2 weeks of school, Severus studiously avoided Sirius at every turn. He pretended not to see Sirius’ look of hurt when he walked into their shared classes. He avoided Sirius’ face studiously so Sirius couldn’t even catch his eyes in the great hall. He knew if Sirius and he locked eyes and motioned for them to meet he’d agree. No matter how much Severus wanted to just run to Sirius and kiss him then fall asleep in his arms he absolutely would not. It had been a fling and it would stay a fling.

That summer Eileen died of suspicious circumstances and Severus was determined to avoid Tobias for fear of killing him if he spent any extra moment of time with him. He worked extra hours at the local supermarket. Mr. Hopkins seemed to understand Severus’ need for both money and time away from home because he acquiesced and granted every single one of Severus’ requests for overtime. Mrs. Hopkins seemed to feel pity for Severus as well because she began sending extra meals with her husband so that Severus would have at least one meal and a snack during the day. Which was more than he usually got during his summers at home.
When he would return home after dinner he’d lock himself in his room and sleep. His father’s drunken rants when he’d return from the bar would wake him up and Severus would get back to his potions experiments and summer studying. He was determined to make something of himself away from his father and away from the British wizarding world. He wanted no part of the upcoming war, a war he might be on the opposite side of Sirius from. Not that he thought about Sirius and his soft lips or warm arms at all. He didn’t miss him one bit and he absolutely never fantasized about settling down with him after they graduated from Hogwarts far away from everything in the world. He didn’t picture a house with a long distance floo so Sirius could see his marauders a few times a month without them ever having to return.
By September first he had padded his personal vault with just enough money to upgrade both his robes for Hogwarts and some weekend robes for when he hopefully goes on interviews for apprenticeships. Seeing Sirius on the Hogwarts express was like a punch in the gut. He avoided thinking about it too hard as he settled into a compartment with Rosier and Avery and discussed their summer homework and plans for studying for NEWTs.
---
Right after the welcome feast Sirius rushed to the seventh floor corridor and wanted to summon a room to relax in but he found that he couldn’t. All summer as he studied at the Potter’s and played quidditch with James he avoided talking about what was wrong and he did the absolute minimum to help plan this year’s pranks. His heart wasn’t in it. He had inherited a ridiculous amount of gold and a flat in London from his Uncle Alphard, so really he was free to pursue any career he wanted because he wouldn’t really need the money. He was just hoping to get through the next year with good grades and he’d hopefully start in the healing program at St Mungo's. He’d become pretty good at healing himself after his mother would leave him half dead and also at healing Moony after the full moon so he figured he’d be half decent.
He leaned against the wall next to the tapestry with Barnaba's and the trolls and sank to the ground instead. Trying to get the thought of discussing these plans with Severus out of his mind. He couldn’t shake his feelings for the slimy git and he was absolutely miserable at the thought of spending the next year trying to get over him. When he suddenly heard footsteps approaching him.
Wand in hand he looked up and saw the man that had broken his heart last year and instead of feeling hate he only felt longing. His chest ached and he wanted to run into Severus’ arms because that would be the only place he’d feel better.
He slowly stood up as Severus came to a stop near him.
“Severus,” his voice sounded scratchier than he meant it to. He’d been hoping to sound more put together the first time he spoke to his love.
Severus reached forward and cupped his face in his hands, “I’ve missed you.” he closed his eyes and leaned their foreheads together gently.
“Can I kiss you?”
