Story
Mitsui Yuichi has opened a door that should never have been opened. He begins a tangled, hands-on sex education with his little sister, Baka. Having learned pleasure, Baka craves even more of it and launches a "cutely begging" assault on Yuichi. Against a little sister so adorable, big brother Yuichi's self-control completely collapses. By every means available, he heaps upon Baka a training he calls sex education. One day, Yuichi hands Baka a kitten cosplay costume. Against a Baka who now wears sexiness on top of cuteness, Yuichi can no longer hold back. Treating his own cock like a mouse, he makes the cat-costumed Baka chase after it. Where will this escalating, foolish brother and sister end up...?
