A sadistic lolicon older brother plays a prank on his submissive younger sister "Kyoka" and gives a bit of hard sex education! In order to meet the expectations of my beloved older brother, I study hard about sex! Kyoka-chan, a M child who grows more and more horny! Before I knew it, I had turned into a masochistic girl who got excited when my brother hit me on the buttocks and made me crazy.
