Slash. HPSF Harry/Seamus Fifth year kinda happened, but Sirius didn't die. No HPB or DH. Seamus decides he wants his lover to meet the family. God help them all...
Though they included Peter, Severus and Sirius could no more care for him than they did for what house they were in. Warnings: LEMON, threesome-ish, mild cussing. One-Shot Generator Story!
Antonin Dolohov take in Harry Potter and Remus Lupin after the Final Battle. Remus Lupin/Antonin Dolohov/Harry Potter slash. Alphebetical Challenge by Kamerreon. Slash. RL/HP/AD LEMON M for a reason
Sirius and Severus find their tenderness again, years later and after a few explanations. Can be read alone, but is the sequal to Tender With an Unwanted Presence and Intermission Sirius/Severus SB/SS Slash AU-ish
Response to challenge by Kamerreon on her profile page. Harry Potter meets an old aquiantance and things happen. Terence Higgs/Harry Potter TH/HP Slash
Because everybody has a heart. Sometimes it just takes a lot to make it show. SSHP Harry/Severus
Because maybe James owes Sirius something. Mentions of Slash. SS/SB Sirius/Severus Sequel to Tender with an Unwanted Presence.
Peter doubts himself, Sirius encourages him. Could be slash if you squint and and turn your head sideways. I got this off of Yaoi Sakka's Oneshot Generator.
The softer side, and the beginning, of a lasting bond between father and son. JPLP mention.
