Sister Hypnosis ~Taming My Bratty Sister with Hypnosis~

Synopsis

I have a sister with whom I’m on terrible terms.

She’s conceited, meddlesome, and nitpicks me every time we meet—that’s my sister Yuika for you.

I can’t find a single thing cute about her. She’s just endlessly irritating.

Lately, I’ve been thinking about what I could do to change things.

Then one day, I stumbled upon an interesting website.

It introduced something called ‘hypnosis,’ claiming that anyone could easily use hypnotic techniques. I figured why not give it a try and decided to experiment right away…

“This feeling you’ve caused in me, big brother…? If it’s come to this, I won’t let you go until you cum for me…”

What started as a lighthearted attempt at hypnosis took an unexpected turn.

Yuika’s hidden sexual desires came bursting to the surface, and I found myself being attacked without regard for time or place.

Which will give out first—the hypnosis’s effect, or my sanity?

What will become of me…?
