"I want to wash my brother's uncut penis with foam" "I want to see how far the skin of my brother's uncut penis stretches" "I want to measure the size of my brother's penis" "I want to strengthen my brother's premature ejaculation penis" "I want to write down my younger brother's virginity" This is the desire (what I want to do) of Mr. Hibiki Natsume, a super caring older sister (college graduate/occupational OL). I will do it all. By the way, my younger brother is a NEET.
