I only remember pieces but it was a hentai about a guy(mc) who suddenly became rich and had to live in a mansion full of maids, being a hentai he of course has sex with them.

other points:
-at least a volume long if not more
-there were two maids who were like the "bosses" and one of them had a eye-patch
-mc's childhood friend gets later recruited as a maid.
