The caption on the first page 人類(イモウト)よ。これ以上何を望むのだ。 is the catchphrase of shin megami tensei strange journey. It seems it wasn't included in the localized version, though.

Fixed a mistake on page 4, 13 and missing sfx on 20.
Thanks for pointing it out, Boomer30569.

Though it may be erotic to use a toothbrush as a masturbation tool, it isn't very sanitary. Like Komodo dragons specifically evolving highly infectious bites, humans have developed incredibly diverse bacterial cultures in their mouths! Human bites result in infections 10-15% of the time (https://www.medscape.com/viewarticle/739023_3) and in this case would be very difficult to explain. The risk would increase towards the end of the toothbrush's life, and regular masturbation almost guarantees infection at some point. Doctors recommend masturbating wearing shirts, sniffing underwear or staring at Onii-chan's photo.
Please practice incest responsibly!

I would argue against the Yandere tag, Instead going with Male:rape. its a sole male sole female, nothing got Yan'd. a yandere would ruin his relationship with other females.

reading the tag definition, she tied him up to rape him, which the tag might qualify under abduction but pretty sure he easily got his hands free to grope her during the process. he wasn't seriously restrained.

@Red 255
Yandere isn't exclusive to just killing or ruining a character's personal life.
The essence of a Yandere is that she's jealous/possessive, loyal, and obsessive to her loved one.

On page 13, I'm pretty sure her pussy is tightening up around him, not inside of him.

How is it that just by looking at the first page, we know the girl is giving off yan vibes?

@Japz321

True that. But I've been saying several times before that we need a "soft yandere" tag for yandere mangas where no murder/crippling happens.

@classified probably better to have the murder/crippling/life-ruining stuff be their own tags, and then just filtering those out. While there's a variety of already existing tags for the physical blood and guts stuff for the axe-crazy yanderes, I'm not sure if there are tags for the life-ruining type of thing.

Sorry to say this dude, but you did this to your sister. Saying weird things to her while she was asleep at a young, impressionable age.
