INFO:
a 1-episode shotacon yaoi hentai OVA made by the same studio who brought us Boku no Pico apparently it's based on a shotacon yaoi hentai manga series named Shounen Maid Kuuro-Kun which ran from 2005 to 2013 and oh boy, it's just as atrocious as it sounds in fact, I personally think this is actually worse than Boku no Pico imo it really speaks for itself
