This is my favorite game on this site. Yes, it's even better than Milfy City or whatever.
The writing is spot on, the characters have dept and their motives sound convincing. The game is exploring a concept that I think is underused. Free use is one of my favorite kinks of all time, and the best thing is that this game makes it work in a believable context. The game also doesn't waste your time with puzzles or fetch quests, it works like a visual novel with just the right amount of choices and consequences. And there's always a sexy mood going on without the feeling of it being forced or rushed.
I believe this game is made using Honey Select, but differently from other games using the same engine, the graphics are tweaked just right, and the dev has a good eye for poses, camera angles, and overall cinematography. He also seems to know exactly what to describe or put into a scene to make it hot.
Overall I'm really impressed with this game, especially considering that the dev doesn't seem to be earning anything from it. If he had a Patreon or a Subscribestar I would definitely throw him a few dollars a month to keep it going.
