About this work

Mio, who lives with her parents and younger brother as a family of four, finds that her brother learned “konnyaku masturbation” (コンニャクオナニー) from a porn magazine he picked up on the street. To teach him correct sexual knowledge, she proceeds to give him sex education using her own body... A serious but horny big sister gently and seductively guides her brother with earnest sex education!
