I'm looking for a doujin by Horihone Saizo in which a boy is turned into a Dickgirl/futanari by his little sister with the help of a tiny demon in a bottle that also turned the sisters friends into futanari and then turns a bunch of people at school into Futanari. I found it with google easily some days ago but forgot to down load it and now i can't find it again.
