Characters: shinji matou/rin

Prompt: noel just wants to take something from ciel, it doesn’t matter what that is, she just deserves to feel some of her pain. she wasn’t an idiot- that much of one anyways, she could tell that ciel had feelings for shiki that went deeper than the mission. but she also knew ciel wouldn’t admit to them and that left her with an opening. she would take shiki for herself and force roa to manifest by using her body to pull him out. he wouldn’t be able to resist taking her blood, and she would have the chance to kill him. she could take something from ciel, get revenge on roa, and complete the mission all at the same time! a triple win for her! there’s just one problem with her plan: shiki isn’t roa and she finds herself breaking on his fat cock.

Characters: noel/shiki tohno, ciel/shiki tohno (implied)
Possible follow-up: dead apostle noel/shiki tohno

Prompt: the holy sakura war. sakura matou being the vessel of the lesser grail has consequences. every servant summoned shares a face with sakura matou. and a core love for her senpai. they all want emiya shirou and won’t let him say no. their masters often get dragged along. first chapter is probably just shirou’s servant, kama? bb is probably sakura. follow up would likely involve the other sakura five, parvati, martha, rin, caren, illya, and potentially more.

Characters: shirou emiya/sakura matou, bb, kama, parvati, meltryllis, passionlip, kazuradrop, bb dubai

Notes: starts same as of fsn with shirou nearly getting killed by one of the servants (melt probably) and saved by rin and her servant (probably kazura?). shirou summons kama when melt comes back to finish the job. kama drives her off and immediately wants to fuck shirou. shirou can’t resist the more mature version of his kouhai and falls into bed with her. he is more dominant than either of them expected. full war is people falling into his bed. master servant pairs are likely: kama/shirou, sakura/bb, melt/caren, bazett/parvati, rin/kazura, illya/bb dubai, luvia/lip.

Prompt: at the end of heaven’s feel shirou was left without a body, his body destroyed by the grail. rin tohsaka and sakura matou had sought various puppet masters in their pursuit of a new body for shirou’s soul. the most they had found after years of searching was a used puppet body tuned to someone else. but, after years of searching, rin had found the sealing designee, touko aozaki and convinced her to meet with shirou emiya about a new body. the two of them leave sakura in fuyuki (now married to shirou) and go to see touko. touko meets with shirou in private and coordinates the design of his body, after he admits to her in private that he has a reality marble. touko does not charge them cash for their services, instead demanding shirou enter her service for a year. rin and sakura agree against shirou’s initial protests, not willing to rob him of a body forever out of impatience and selfishness. touko initially plans on using shirou as a runner and incredibly useful agent with his arsenal of noble phantasms, and the opportunity to study his reality marble. touko instead finds herself falling for shirou’s charm. and when he awakens with a foggy mind from the body transfer (the murder of his temporary vessel), touko sees him naked. she can’t resist his 13” penis and steals him away from his fiance, sakura, taking him as her own for more than the one year he is indentured to her. this summary needs to be rewritten.

Characters: shirou emiya/touko aozaki, sakura matou

Notes: fucking depressing as it would be less seduction and more shirou falling back into being a sword instead of a person.

Prompt: in mahoyo it is revealed that astral bodies don’t have a clearly defined form, but can shift to suit the whims of their master. when gordes musik (goredolf’s father) summons the flatchested elizabeth bathory in apocrypha, his desire for eye candy and a sexual partner causes her to become a big-chested bimbo slut.

Characters: arcueid/shirou emiya, yu mei-ren

Tags: okita alter/kukochihiko (wolf guy), maybe more idk, bimbo stuff

Prompt: musashi and shirou fluff post “a pair of reckless swordsman”. as much smut as it is just cute relationship stuff, and the story of their grail war.

Tags: musashi/shirou, sequel

Notes: alternate option is that musashi does have to leave after the war and winds up back at chaldea in arc 2. when she finds muramasa in the olympic lostbelt, musashi won’t hear a no and fights to get her boyfriend back in control of the body and with her. probably involves her agreeing to "betray" chaldes and cut down atlas. i would not be killing musashi against chaos. (this is the version i'll do)

Prompt: shirou from ubw winds up in the past during fate/zero. he convinces tokiomi to eliminate zouken and take sakura back from the matou. tokiomi was reluctant in spite of the horrible shit zouken is doing to her, because the tohsaka’s only have one crest, so only one daughter can inherit. except… shirou emiya also has a magic crest- a tohsaka one. the one he received from rin so he could fight gilgamesh. he just had to transfer it to a tohsaka so that it could be inherited by sakura and she could have a place as rin’s sister. the problem? to transfer a crest to someone without the same blood- or from someone outside of the same bloodline, one had to use a tantric ritual. he obviously was not going to be asked to fuck a five year old sakura, or even the seven-year old rin… but there was another tohsaka that he could transfer it to… tokiomi’s wife… aoi tohsaka. tokiomi was willing to give us his daughter to increase their chances at reaching the root, giving up his wife was hardly a line he wouldn’t cross. perhaps it should’ve been because aoi tohsaka really liked the feel of shirou emiya’s cock, and the person he was. she maybe wouldn’t mind if rin and sakura had a new… a better father. okay, she would mind it very much, she wouldn’t be able to live if shirou was not in her bed every night.

Prompt: jason was trying to recruit a new group of argonauts to replace the old one that doubted his brilliance. medea lily was skeptical that he would be successful in his recruitment pitch, and did not want to see her lord jason displeased. so she took things into her own hands, offering her body to a few male servants of great power in exchange for them joining the argonauts. arjuna alter, mephistopheles, and an edison/tesla threesome.

Tags: medea lily/arjuna alter, medea lily/mephistopheles, medea lily/tesla/edison

Prompt: unspecified servant loves her (unspecified) master, but her master does not have adequate magical circuits to supply them with mana. she wanted to marry her master, but she could barely even stay materialized during the war, let alone after it. so she would have to find an alternative source of mana to win and stay with him forever. she would not let herself prey on the lives of others but... there was another option. to stay with her master, she would betray them. by sleeping with dozens of other guys regularly to get the charge she needed. it did not matter if they fucked her better than her master, she would still only ever love her master.

Tags: cheating out of love, gangbang?, idk this is very not fleshed out. no clue who master or servant should be either. first thought was medea but no justification for her not using a leyline or any caster really. ideally should be someone without circuits as master?

Prompt: sion’s alter ego in paper moon existed to give her a chance to be a friend to ritsuka. maybe, it wasn’t quite the ritsuka she knew- a hollow and lesser version, even. sure, she might be in the body of a child, but she was going to take full-advantage of the situation to indulge in all of ritsuka. she might have to compete with a god of love who desired to be loved in return, but that wasn’t going to stop either of them from taking all of the ritsuka alter since they could not have the real thing. sion had always been bi anyways, so the more the merrier.

Characters: sion/kama/ritsuka fujimaru (male)

Prompt: shiny star is a ploy that is meant to grant one’s greatest wish if it is entirely unique. had kinomi stumbled upon the play just two days earlier his wish likely would’ve been different, more selfless, but after seeing the usually antisocial alice bathing nude in the hot springs in the middle of the night, kinomi had been unable to think of anything but her. he wanted her to be his loyal slave, only craving his cock and worshiping him as a god. for anyone but alice, that wish wouldn’t be unique, but alice had seen so few men in the last five years to be craved by anyone else in the same way. and the few men she had spoken to all treated alice with respect and valued her independence, even the ones who lusted for her. his wish was unique and so it was granted. kinomi is happy with the result to say the least.

Characters: kinomi housuke/alice kuonji
