Saiin Shimai ~Namaiki na Itoko-tachi o Saimin Appli de Otonashiku Saseyou to Shitara Kaeriuchi ni Atta Ken~

This summer vacation, my parents and their families are going on a long vacation,
and I'm left to take care of my two younger cousins.
Worse yet, those two cousins are super annoying.
Even worse, I'm a lolicon, and their sexy bodies turn me on like nothing else.
It's only been a few weeks, but I'm at my limit. I don't even have time to masturbate in peace to cool off.

It's time for my last resort...a hypnosis application so I can get these girls to calm down a little.
I wouldn't do anything nefarious, I just want to jerk off.
However, it turned out my cousins had a hypnosis application of their own, and planned to use it on me...
