My latest work is a novella, a steampunkish (steam power isn't widely in use just yet though it is being used for large industrial purposes, like pumping water out of mines) variation of the Old West. However, technology is advancing FAST, faster than anyone knows, in the Union, which is what the nascent United States is called in this timeline. Yes, it's an alternate world SF steampunkish sexual bondage erotic romance set in a variation of the Old West. Now, that's a NICHE!
(Actually, I'll call it historical erotica since that's an ACTUAL niche that really exists.)
The basic story is two friends who have just turned 18 go out for a night on the town in Parados in the Republic of Geronimo (think west Texas). Being adult women in a society where religion is pretty much just reverence for nature (and hence sex guilt tripping does not exist) and there's something called "slave medicine" that is a safe, sure, easy and effective method of birth control, they're both looking to get themselves collared and fucked.
Because of course in this alternative world everyone is also into maledom/femsub, basically master/slave sex.
I had so much fun fitting all this into a traditional Old West story. The best part was where I lifted a character from a classic Western comedy movie and put her in my story as is, though in a slightly different situation. (A hint: the movie is not "Blazing Saddles" but it is also a very funny movie that satirizes Western tropes very effectively.)
I also had fun inventing some bordello tech in a world without steam power.
I'm also very pleased at how the cover came out. It's basically two images that have been merged to form one. I spent hours looking for the right stuff on the commercial art site I use and found these gems. It wasn't luck, really, I took some deep dives into some rabbit holes on the site to find just the art I was looking for.
And the sex scenes were fun, too. I built toward the big sex scenes by including short sexy scenes in which Matty and Arlene meet various friends in town, including one in punishment stocks who's getting vigorously "punished" at the time (she's basically free use while in the stocks) one who's a pony girl, and one who's a slave whore with a tale to tell about how she became one. By the time Matty and Arlene get tied up and have their big sex scenes with their hunky Masters, they are, well, "hot and bothered" barely describes it!
Of course, I could be lying about all this. But I'm not. Read the book and find out... I dare you!
