As was shown previously, there’s a nudist beach in Inujima City that caters to futanari customers. The only rule is: no boners.

However, as this doujin will show, there’s a small secluded beach nearby where those rules are not enforced. So when Rin, Milky, Hazumi and Eru have a beach volleyball match in the nude there, things get very heated very quickly.
