The first time Sirius Black realised that he was in love with his best friend was when the four boys was sitting by the lake staring at Sirius younger brother laying on the grass snogging his boyfriend.
"I wish that was me and Moony" he thought.
He bit himself in the lip, glanced at the boy sitting next to him as if the boy could read his mind, and blushed like he never done before.
Actually, Sirius had never blushed at all before, he had never had a reason for it since shame was not a word he was familiar with. But he was pretty sure that if Remus had known what Sirius thought about this moment he would be terrified.
His eyes went back to the scene in front of him, where his little brother now had his fingers entangle in the hair belonging to the boy laying underneath him. He was straddling the older boys hips and actually seemed to grind a bit. Both the boys looked very much a like, they had naturally black long hair and Sirius brothers hair fell down and shielded most of their faces, which made it hard to see the intense kiss. They were both skinny and short and quite vicious. People that never had met them before often thought that Regulus, that was Sirius younger brothers name, and Severus Snape were twins or at least brothers, but that was far from the truth.
"That's" James said, sounding a bit hoarse.
'It seems I'm not the only one affected' Sirius thought and tried hard to not think about that it was actually his own brother that he stared at.
"yeah" he said, not really knowing what James meant, but was pretty sure he did.
"Professor McGonagall on her way" Peter said and the boys ripped their eyes from the snogging boys and over to where one of their professors came.
"Maybe we should warn them" Remus said, looking worried.
"Why should we?" James smirked and Remus bit his lip nervously.
Sirius eyes caught the sight of Remus' lips and felt faint, such beautiful lips he had, even though he had a scar that ran through the lower lip. Sirius couldn't stop himself from thinking how that scar would feel under his tongue. But then he heard Professor McGonagall shout.
"Mr Black and Mr Snape, stop that instantly."
Sirius saw his brother jump back, but his fingers where still entangled in his boyfriends hair which made the other boy yelp in pain. Regulus tried to disentangle himself at the same time as Professor McGonagall was scolding them.
"That is not appropriate behaviour. 10 points from Slytherin."
The boys finally got up to their feet and didn't look guilty at all, just sullen and quite pissed of being interrupted. The Professor saw the other boys sitting not far away.
"Mr Black, why did you not stop your brother? You know the rules of this school"
"I can't stop my brother" Sirius complained. "We were just sitting here minding our own business when they came and started to assault each other."
Professor McGonagall looked scandalised at Sirius chose of words but he didn't care. Trying to put the blame on him because of his brother, that was just rude.
Regulus and Severus gave the four boys an evil look before they left the crime scene.
Sirius glanced to his left where James was slouched back, his eyes behind his thin rimmed glasses where dimmed but Sirius was sure it wasn't boy on boy sex he was fantasising about. Not like Sirius did, he glanced back at Remus, the boy in his very recent dream, and saw that he was still biting his lips. He was hugging himself, holding his robe close around his body and looked so fragile that it hurt in Sirius' heart.
"You ok?" He asked and flung his arm around the smaller boy.
"Yeah" Remus said giving him a shy smile which made Sirius breath hitch.
'This isn't new' Sirius thought 'I've just tried to ignore it before. I'm in love with my best friend'
