Atrocities

> Isekai
> Rape
> Drug
> Monstruous cock
> Twisted Seme

I love that uke is helpless to stop being raped despite not being bound. Seme seems to be obsessed with uke (yandere vibes?). There is a minor plot (maybe to make the reader less sympathetic with the uke) but it's mostly unholyness (and dark)
*The first posted chapter has bad translation*

3/5 - Seme's gigantic cock scared me and I wish he had played with uke more. It was 80% seme pounding uke's ass

Pet to Mitsugetsu 

> Captivity
> Urethra play
> Rape
> Big tits

Uke is being kept as a sex toy and attempts to escape. I feel like there's a lot of plot that they could explore, such as how the uke was captured and how are the protagonists related to the guy being tortured in the sex tape
3/5 - The sexual torture scenes in the sex tape were very hardcore

>Sex Toys
> Nipple Development
> Crossdressing
> Gangbang (forced)

Uke is selected to act as the all boy's school "Princess" (basically becoming a whore). Love the training and the mind break process, but I'm really here for the sexy nipple development and crossdressing (he looks so adorable with the slutty cat outfit)
4/5

> rape
> sex toys
> ejaculation denial
> nipple play
> restraints
> mind break

Uke is captured, trained and remodeled to become a "female" whose purpose is to please men. He is stripped off his rights of feeling pleasure as a male, learning how to feel it as a female instead.
4/5 - I think the detail that it was mistakingly ordered by his dad threw me off a bit (specially in the final scene)

Hasshaku-sama Forcibly Inseminates Cuntboy

> Rape
> Humanoid Monster
> Cuntboy
> Body Modification
> Mpreg

Uke enters his grandmother's house to find Hasshaku lurking around. The yokai then decides that uke's going to bear its children, turning him into a cuntboy. Call me a freak, but I think the kissing scenes with the yokai's long tongue are very yummy.

3/5 - tbh I'm not that much into cuntboys

COLORED UNCENSORED VERSION

Link falls prey to the Yiga Clan, which holds him captive as their sex slave, training him and drugging him until his spirit breaks.
4/5

> Captured
> Bondage
> Rape

Hero defeats the demon lord and decides to make him his pet. I like that the hero is both forceful and a scary sadist as he is caring.
3/5

BY OinkO (Nanai) (man do I love this author)

> Tentacles / Monster
> Rape
> Inverted Nipples
> Mind Break

Uke is at the beach when he suddenly comes across a tentacle monster that feeds off of his "Life Energy" (cum). He relishes so much in uke's life energy he decides to make uke his bitch, keeping him on edge to make him come back on his own (forced) will
4/5

Also by OinkO (Nanai)

> Sex Toys
> Gangrape
> Mind Break

Substitute teacher gives a class on sex education but things take a turn when the students decide to use him as a test subject for the class (testing all sorts of sex toys on him)
4/5

> Rape
> Power Abuse
> Sex Toys
> Restraints

Seme uses his captain influence to keep and force uke to do as he pleases
3/5
