I'll teach you what men really want Vol.1 (TL Manga): Cohabitation rules etched into my body

"Want me to teach you just how scary a man can be?"
If she breaks a rule, an erotic punishment is waiting for her! Aki lost her parents when she was young, so she was taken in by the old man who lives next door. Afterwards, she started living with his grandson, a calligrapher named Akinari, and soon fell in love with him. Then, when Aki's 20th birthday rolls around, he hands her "A rulebook for living together from 20 onwards," and tells her that if she breaks the rules, they can't live together any longer. "If you can't remember them, then I'll just have to teach them to your body!" Akinari strips Aki and begins writing the rules on her body... What will this spine-tingling sensation and humiliation bring for Aki!? Vol.1, 50 pages.
