You were a Marauder and you were Sirius' brother, you were friend with James, Remus and Peter, you and Sirius were two massive troublemakers, always in the problems and detention.

You and James always got tension since fourth year and finally in sixth year while James was with Lily, in a relationship, James was cheating on her with you, your brother knew about it.

Everynight you both would be in the common room, the only light being some candles as you both kissed either James is sitting on your lap, or laying on the couch, and pinned against the wall or just in your arms.

Tonight was the same, as everyone sleep, or that's what you thought, Lily was still awake just not aware what was happening in the common room.

You were pinning James against the wall, kissing him slowly, James was gripping your clothes with his hands while you were holding his hips.
