I can't stress enough how good the works of Sakana Toujo are. This is not an exception. Whenever you want to read a story with lots of hot consensual sex, this is your manga.There is no big drama and the chapters are filled with fluff and sex.The premises of a cute innocent succubus and a man who suffers due to his monster schlong are quite funny, but this is not a comedy, is a full romance (for mature audiences).
