I don't think I have anything too crazy to recommend but here's what I got
There isn't really a main character, but you're managing a goblin burrow to capture women to impregnate and breed stronger units. Aside from raping them, I believe you can force some of them to eat the lovers that you murdered.
Goblin Burrow
Goblin Burrow: I'll Borne
Goblin Burrow: the Fable (TL WIP)
You play as an orc and force a samurai to breed you an army to take over her country and kill her lover in front of her
Pig Demon and Female Samurai
You kidnap your crush and stockholm, mind break, and impregnate her, you can also abduct her friend and random women to sell into sexual slavery on the local black market. There's also a good ending where you just make her fall in love with you in the first act that ends the game early, though in the same route you can take advantage of that trust to have her follow you home to kidnap her. Also the scat tag is inaccurate, it's only urine and it can also be disabled in the options.
Until "My Girlfriend" is Pregnant - Abduction, Confinement, Impregnation
Also a side game from the POV of three female characters, the main girl from the above game, her friend, and a club hostess
The Dangerous Road Home at Night - Raw Rape, Abduction and Confinement
You kidnap women to train as prostitute slaves and climb the ranks in the local underground pimp racket
SoldGirl Town
Both games you kidnap a classmate to train sexually with different endings depending on the way you've trained them, including "disposing" of them since you've gotten bored.
Sealed Room Breed
Sealed Room Breed 2
You are the big bad evil guy
Corrupted Saviors
You can play as any of the tohou characters, but also make your own, and take over the world. A little hard to break into but once you do you can pretty much do anything want with whoever you want, warcrimes included. There's also a cheat menu that makes the wargame aspect easier if you're a casul like me. Really great game if you're fine with text based games.
