お兄ちゃんの性癖、私が見つけてあげる♪ ～今日から僕は妹のオモチャ～

"Wow... You went to the trouble of making something like that and masturbating using your sister as material, big brother... Gross."

My sister's scornful gaze and words...
And then my sister hit me with the final blow.

"What will happen if our mom hear about this? We might get kicked out of this house, big brother."

"I'll do anything, so just don't tell our mom... Please let me off the hook this time."

I pleaded with her with a bowing heart.

"Hmm, you'll do anything for me... Then..."

And so began my days of being at my sister's mercy...
