One day, the adventurer Sora wakes up inside an unfamiliar mansion. (Name can be changed.) This mansion is inhabited by cow girl maids who trapped Sora inside, all because they wanted a cute “master” to serve and take care of.

The cow girl maids try to pamper Sora with their breasts and force an addiction on him. Will he manage to escape before succumbing to the cow girl maids’ temptations and being turned into their true “master”…!?
