All the magic drugs sold out today.
Not that I cared whether they sold or not.
The only reason I sell magic drugs in town is so I can watch cute boys.
Their small, innocent faces, their naïve and adorable gestures…
Just that alone is enough material for me to masturbate to when I get home.
I’ve been holding back for days.
My body’s been aching with desire, but I kept restraining myself.
I wanted to build it up and then release it all at once.
I was planning to masturbate as much as I wanted today…
But on the way home, a cute boy bumped into me,
and my mind went completely blank — before I knew it, I had brought him home… ♡

Our protagonist, Yuu, ends up spending his summer vacation at his relatives’ house in a rural town.
He is warmly greeted by the three sisters who live there.
When he meets the sisters for the first time in a long time, they have become very interested in sex, and the same can be said for our protagonist, Yuu.

As a hero, you must resist the temptations of monster girls and older women in this RPG to defeat the Demon King and bring peace to the world.
However, the monster girls use all sorts of sexual seductions to tempt the hero, and he ends up masturbating himself…
He indulges in the breasts of older women, his penis feeling great, and as a hero, he should be saving the world, but instead he is enveloped in the breasts of monsters, made to fawn and verbally abused, and ejaculates with a sense of both happiness and guilt.
You can enjoy seamless combat and eroticism, with monster girls using various methods to seduce you during battle, and if you lose, you’ll end up having sex on the spot.
