   Summary

   When Remus is away visiting his family Regulus has the idea to get James all needy and then send his puppy dog boyfriend down the hall into his brothers bedroom so that Sirius isn't so lonely.

   this idea came to me and I swear I blacked out and then all the sudden this was in front of me :)
