Sirius’s POV:
Remus was acting weird at dinner that evening. Sirius was thinking of this whilst trying not to fall asleep as he walked up the stairs to his dorm. It had been a long day and he was ready to go to sleep (maybe that’s why Remus left early?). Fate had other plans in mind.
When he opened the door leading to the dorm he squeaked in surprise. There lay Remus Lupin. On his bed. Touching himself.
Sirius rushed out an apology and hurriedly slammed the door. He tried to will the image of Remus out of his mind. It didn’t work.
He rapidly became hard too at the mental image. Sirius decided that if he can’t sleep, then might as well take a shower. And maybe solve the other issue too while he’s at it.
So here we are. Sirius Black standing under the running water, thinking about his friend(who almost certainly doesn’t feel the same).
Not just thinking about him but also pretending he was the one stroking Sirius’s now very hard cock.
Soon Sirius came before going back to the dorm, making extra sure to knock first this time.

Remus’s POV:
Remus walked up the stairs -hoping his friends didn’t notice the abnormal time of departure. Sirius had done something to make him very horny.
He was in such a rush he wasn’t sure whether he locked the door or not. He was thinking about Sirius stroking his cock while he jerked off.
In his opinion this was an impossible fantasy that could never happen.
A squeak pulled him out of his thoughts and he saw Sirius. Sirius mumbles something like an apology with something about how he should have knocked.
To say Remus was embarrassed was an understatement. But he was still very hard. His mind made up a kind of story to play in his head.
In the “story” it follows Sirius, right after that recent interaction. His mind showed an extremely embarrassed Sirius, turn to an almost even more horny Sirius.
Remus came fairly quick and gets dressed and uses a cleaning charm. He soon heard a knock on the door and simply said “come in!”.
The end.
