Ruining my harem in a prison themed tavern
Finding ntr games of your favourite anime sure is hard; but in this case, you have a really large harem at your disposal, coming from several anime series, ready to be corrupted. (Even if game goes more towards netorase [sharing] than cheating, and the main love interest of every girl will still remain you, the mc)
You are a normal guy, but extremely popular among girls; after speaking with your friends, you find out they (and some of your family members too) work in a weird prison themed tavern, as waitresses. Though serving food and beverages is not the only task assigned to the personnel. Here clients gets a bit handsy, and the tavern proposes special dishes, with waitresses forced to provide extra services. You'll learn to know that every girl has a crush on you, and would prefer to live a peaceful life being your wife for the rest of her life, but your plans differ a bit with that idea...
