Mistress Risa brings her slaves to the Mazo Man Farm, which she visits every year as a summer retreat, again this year. This masochist farm is a secret human farm where mistress Risa keeps her slaves as livestock. When mistress Risa arrives at the ranch, she finds a cardboard box delivered to her, with a still-standing box inside that she bought at the slave market. A man who is not a masochist is tied up in the farm. A new slave joined the masochistic man's farm and mistress Risa trained them in the open air for a summer. Enjoy your vacation.
