Remus had always loved Sirius.
It started with a small crush when they were in their fifth year and only developed over time. But he knew Sirius wasn't interested in him like that or at least that's what he thought. One afternoon, he and Sirius had to clean the potion classroom as a detention. “If you like potions so much then you sure have no problem with cleaning them up." McGonagall had said, after him and Sirius were caught putting hair growth
Potions in the Slytherin’s water, they deserved it if you ask Remus. But he was pissed, pissed at the Slytherins at Peter and James, who were supposed to hex the Slytherins hair to Gryffindor-red but it didn’t even got to that point.
He was especially pissed at Sirius, who was at the opposite part of the room cleaning the tables. The full moon was just a few days away and Remus’s emotions were all around. Not forgetting that their final exams were coming up, in a few months they would be graduating. Remus was stressed and Sirius had nothing better to do than keep on talking and talking about how this was all Remus’s fault. It was not his fault and it was going on his nerves that Sirius pretended it was.
“Can you just shut up?!” Remus yelled.
For a second Sirius looked surprised that Remus had raised his voice, put the surprise didn’t last long and changed in a matter of seconds to anger.
“ No I won’t. Just because you can’t stand being wrong doesn’t mean I won’t tell you.” Sirius said, also raising voice.
Both of the boys stop what they were doing and Remus crossed the room. Now he wasn’t even three steps away from Sirius.
“If I was you, I would know what’s good for me and shut the fuck up.” Remus said.
“ What if I don’t, hm?” Sirius shot back, stepping closer “ What will you do then ? Make me?” Sirius looked at him, twisting his head slightly to the tight.
This wasn’t a good combination, him a few days before the full moon and Sirius with his stubborn mindset. But he was to provoked to let it go.
“Yeah, I will make you.” Remus stated, also stepping closer.
He could feel Sirius’s breath on him, if he wasn’t so angry he would be aware of the situation they’re in. Him and Sirius, Faces just centimeters away from each other, close enough to feel the heat of the other boys body.
“Then make. me.” Sirius said in a smug voice and Remus mind went blank.
He shoved the smaller boy against the wall behind him, trapping him with his Arms. For a second he became aware of the Position they were in, he had Sirius Black pinned against a wall , in an emply classroom and the next time someone would check in on them was in a proximity 15 minutes.
Remus decided that that would be enough. With his free hand he grabbed Srius's chin, the other boy went silent after being shoffed into the wall. Remus lifted it up and could feel Sirius’s chest breath against his lips. “Look how easy it was for you to shut your mouth.” Remus said, his voice coming out as a husky whisper. Sirius let out a shaky breath, eyes wide open and Remus could feel Sirius gaze drop to his lips. Almost automatically he licked over them.
“Moony I-“ Sirius was interrupted as Remus pressed his lips against Sirius’s hard. Immediately Sirius kissed him back. Sirius ran his hands over Remus's back and finally buried them in his brown curls.
At the same time, Remus let his hand, the one he wasn't using to hold up Sirius's chin, wander down Sirius's torso at the side. When he reached the younger boys waist, he pressed it with enough force to make Sirius‘s mouth fall open but not enough to seriously hurt him.
Sirius made a surprised sound and Remus grinned before pushing his tongue into the other’s mouth. Sirius laid his head back against the wall and pulled at Remus‘s hair so the taller boy would follow after him. Remus let Sirius’s chin go and put his hand to the other one on Sirius’s waist.
Both of Remus’s Hands rested on Sirius’s waist, as the smaller one decided to bit Remus’s lower lip. And something like that wasn’t going to be just accepted, so Remus slippet one Hand under Sirius’s shirt and let it wander up the other boy’s chest.
