After spending some quality time on the beach with Milky in Joint Futanari Practice 4, Rin decides to get a summer job at the nearby Futaya Beach Bar. Since this is a nudist beach, she has to serve the customers naked.
The customers themselves are all futas and they can get a bit “hands on” with the waitresses. Not really a problem, since the bar has a very wide range of services and meals they serve.
