Remus Lupin was a master of the subtle touch. The way his fingers would brush against Sirius' hands as they walked down the hall, those light touches along his back or arms that no one else would notice. A few days before the boy had actually had the audacity to lick his ear when he had leaned over to pass along a message from James. Sirius Black both loved and hated him for that particular talent.
On the one hand every time he had any kind of physical contact with his boyfriend he felt like he could fly. The attention provided him with the consistent reminder that the werewolf still shared his feelings. He loved knowing that Remus was his and that he was Remus'.
But on the other hand it was driving him absolutely mad. Every time his heart would jump into his throat and he would have the overpowering desire to just rip off Remus' clothes right then and there and take his boyfriend into sweet bliss. Unfortunately the boy would just give him that little smirk and act as if nothing had happened.
It was infuriating. That he could reduce Sirius' mind to his most basic desires with a single touch of his fingert-
And there he was, doing it again. The werewolf had just ran his fingers across Sirius' shoulder as he walked past, probably coming in from Prefect duties or what have you. When the animagus whipped his head around he was greeted with the usual 'innocent' smile as the other boy continued on towards the dorms.
Oh he was going to pay for that…
