If you're looking for a Stockholm Syndrome incest mystery (although that's a very specific thing to look for) then the story "Time Traveling Sister Wants Brother To Rape Her Past Self" might work, but it's an incomplete story set to Public. The sister of the story goes back in time to record herself being raped by her brother, but this causes it to not happen.
I’ve always wanted to flesh out my comedic one where the reader repeatedly misses out on all the sex scenes because of uncontrolled time travel. Nothing like seeing a hot celebrity, flashing to exhausted with her complaining about her ass being sore and then flashing to sitting in your car outside the house with three other celebrities waving goodbye wearing just towels to annoy the reader lol
I've thought about starting up a time travel story where someone from the modern era goes to a Medieval period. There have been a few movies on that subject. Black Knight comes to mind and I think there was another one with a similar premise. It's been a long time since I've watched either film, but definitely have been in the back of my mind for a story on Chyoa.
I'd liked to have watched the film where Marty just decided to hell with it and slept with his 18 year old mom.
Honestly? You lost me at '18 yo Hermione Granger' but yeah, that could work too. Short term time travel are usually about switcheroos, incest and "Count of Monte Cristo" stories after all, you just added your own twist.
Guys, guys: Bill and Ted, but for sex. Think about it; a doofy highschool coomer needs to make a presentation for history or he flunks, so he goes back in time to collect a bunch of bodacious babes to have a proper presentation on the history of sex. Sex happens. On a more serious note, I feel that anyone who wants swords, sandals, togas, slave girls and/or big, poofy dresses would just write or read on of the many fine Fantasy stories on the site. Fantasy is basically just history only with less smallpox and genocide. Plus, any historical story is going to get shat on by dudes who think they know better (or want to show off the fact that they DO in fact know better) and get up in arms when the spank-off story written for free as a hobby isn't Wolf Hall or something. No one wants that...
Yeah, but I wanna go back to Toga days, ready to storm Rome with my Smith & Wesson Boom Stick and a pocketful of viagra to help me make it through the whole harem in one go! (Yeah I know Rome wasn't where you got harems but I'll figure that out when I get there).
