Futanari beach and beach house. It's so simple, but so perfect. We need to get on this. The best thing is that, through the use of futa-cock mixers we will take thousands of plastic straws out of the ocean, and by using futa-cocks for our products like in the book, we can prevent hundreds of tonnes of plastic materials previously used for that stuff from being made. Ultimately, futanari is not just good for your dick; it's good for the world as well.
Seriously though, Hakaba Yodomu is legendary in futa x futa, and their futa beach series is one of the best reads for hentai in general. Thank you for the upload, Nasu.
