I'm searching for a fic

I'm looking for a fic which happened in like the year post war. Where Ron and Hermione are both head boy and head girl. Its a smutty fanfic where after Gryffindor wins a quidditch game and mid party Hermione takes Ron to her dorm and strips for him and then the smutty part
(i think towards the end there is mention of Harry and Ron taking up smoking after the war)
