Tony cheats recs?

Hi! I'm looking for any fics where Tony cheats on Steve. I've found tons where Steve cheats on Tony, but can't seem to find any the other way around.
(I hope I've done this right. This is my first time posting, so sorry if I've done anything wrong :p)

Winter Soldier is sent to kill Tony

Are there any fics where Bucky, as the winter soldier, is sent to kill Tony? I sort of remember passing by a summary of a story to that effect but I can't remember where.

Thanks in advance :)
