ROE-124 Help my husband's son know how to fuck each other

It's been a long time since my husband went on a business trip away from home. My problem is that my son, Chihiro, has reached a rebellious stage and started secretly watching AV. Chihiro used to be honest and cute. I decided to start proper sex education because I couldn't raise the child wrong. That's the discipline of tying up my sleeping son's hands and feet and spanking his butt. Watching my son's butt twitch every time I spanked him made me want to raise Chihiro like a lady and not a savage man.
