This story is a branch story of "Watashi no Fushidara" where a girl who has nothing in life has only one way out, education. Except she's not particularly smart and exhausts herself studying whilst looking after her ungrateful grandmother on top of dealing with being bullied at school.
To get to the heart of the story, the demon from "Watashi no Fushidara" appears and gives her a way out, TIME STOP. But the catch? Her lust increases exponentially everytime she uses the power, so she has to masturbate to get back under control, except it's not enough, so we'll have to employ our hikkiamori childhood
friend to do it instead.
The story continues with her life getting better and better, she stops time, has infinite amount of time to study and do tests properly (what a prim and proper girl), and she has her childhood friend to get her off so no issues right?
THE WORLD COMES CRASHING DOWN. Her teacher tries to NTR her, her grandmother finds out she's going to college, her biological father is a bum, and she loses everything.
The ending is a bit disappointing, which is why this isn't rated higher.
Artistically this is great, the ecchi scenes are 10/10.
