Hey /h/, I come to you in need of help. I don't really browse /h/ or /d/ at all anymore, not in years and many computers ago. So I have no more hentai at all. But for nostalgia's sake, I have a craving recently for a specific manga that I cannot remember the name of for the life of me.

Long story short, I'm looking for the hentai where a kid's uncle invents three robot girls that need to get laid by the kid like clockwork or else they detonate, and at times transform into grown women (or women to girls, I've forgotten).

Webm unrelated, I literally have no hentai so here's a sexy 18 year-old.
