…I like the sound of this one better: Ero-dere.
A look at the “customers who bought this item also bought” list turns up titles like Cool masochist, My maid is a classmate, My little sister is a bikini model, My S big sister and my M little sister, Dangerous sisters, School-swimsuit-maid at your service!, Milk academy, My big sister, My little sister, My maid, My princess, My doll, etc.
I think it’s safe to conclude that the main character lives up to her description. Often. With illustrations.
[Yes, all of the “My X” ones are by the same author. I imagine she got some crossover sales from fans of the Mai HiME manga/anime series when she got up to princesses and released My Hime. Interestingly, they also hired her for a To LOVEる book called Dangerous Girls Talk; sounds like someone qualified to work in that universe!]
