I'm looking for a yaoi/yuri in which the couple starts off by having sex, because they were drunk, raped or something similar. Than later on they hang out, get to know each other and fall for each other. 😀

It's even better if one or both of them thought they were heterosexual before that. 😉

Dounika Naru Hibi the fifth story, drunk sex

Sweet Guilty Love Bites first story "Sweet Guilty" is sex for fun/repayment, second story "Guilty Love" is drunk sex

Yukemuri Sanctuary First chapter is sex before they really know each other just because they like each other...kind of a 'special service', second chapter is sex as a lodging fee, and third chapter is blindfolded sex. The other chapters have participants that know each other well.

Oh thank you. Finally someone replied when I had lost all my hopes.
Thank you! XDD

If you didn´t read it yet you should try out Hidoku Shinaide , it starts out with blackmail/rape.

Kawaii Akuma - the big uke is raped by the cute little seme and is forced into a relationship.

Bannin - the 3th story

Agnus Dei - oneshot from SADAHIRO Mika

Cage - two brothers/incest

Endless World - don´t know if it fits the category but this one is REALLY GOOD and one of the main characters is raped by his cousin and is used by him

Ookami Shounen to Hamu no Hito - this one is bara, but if you don´t mind it read it because is one of the best ones I´ve ever read + drunk intercourse

Kimi de Oboreta Ato wa - ch1-2

I´ll edit when I go through my list...
