Nyotaika shita Boku wo Kishi-sama-tachi ga Nerattemasu
Both yaoi and (m)m/f haha. Uke gets along w two semes, one day gets cursed by chocolate to turn into girl at night until man cums inside him. Starts w one seme, until seme goes to look for something to lift curse and leaves him with second seme. Uke likes them both, curse lifted but some effects continue and uke confesses to both for a happily ever after 3p relationship. Ongoing, but hiatus and resolved enough to mark complete.
I didn't have it but now I do
*paused until more ch* Ch33. Girl confesses to boy. Boy says he is gay. Girl meets yaoi goddess who gives her pills to become a boy for 10hrs or so each time. Starts dating him. Tablets misbehave, now currently stuck on boy mode? Another girl overheard yaoi goddess and girls boymode and wants to help her keep him (in the fave of his ex bf turning up).
Irregular Empress
Girls dad dies, leaving her alone in the world. So she pretends to be her fake twin brother, becomes a knight. Has legendary sword techniques but in order to not have scrutiny of her gender, she stays lowkey and non ambitious. One day comes across prince killing a witch, fights him not knowing who he is or why he killed this girl. Later he trades her money, sweets etc to become his fiancee - he can only ascend throne if he marries, and he needs to ascend to get the holy power to deal with the witches who are uprising. He knows she is a girl, but she doesnt know - so she is a girl who pretends to be a boy who pretends to be a girl lol. Various misunderstandings due to her gender, alliances etc and ultimately she accepts the princes feelings and they have kids and live happily ever after.
Fucked by My Best Friend
Ch63. This is straight and yaoi! Uke and seme have rep for being players, always hitting on girls and doing threesomes etc. One of the girls unhappy with uke wants him to see what its like being a girl on the other side of this treatment and drugs him with a gender changing medication. Seme finds uke, hits on him in his girl form but realises from his stomach scar he's his male friend. He fucks him anyway haha. They find that uke turns into man when he's fucked and came inside - semen balance needed, or he turns back into girl when he orgasms. Seme gives uke a dry orgasm as a guy, and then uke starts catching feels. Uke realises seme likes him too, asks seme about it, seme says always loved you as a man, dont care about your gender. They start dating. Doctor helping them with finding a cure. Another player kidnaps uke and feeds him another pill to try and keep him as a girl - seme saves uke before sexual assault, feeds guy a pill and he becomes a girl (so they can make player tell them more info re pills). Gonna give player girl to doctor haha.
