Anyone else heard of this? Apparently it's called "Dear Furo" and it's by the same person that did Hen na Chishiki ni Kuwashii Kanojo. Apparently it's just about MC being constantly assaulted by a succubus in the bath, but it's almost Kagaku na Yatsura levels of lewd.
Please forgive the shitkaku link, was the only place to find previews.
