We approach female college students in hot spring resorts and have them try out a (embarrassing) game of bathing in a mixed bath in a swimsuit! The swimsuits are so obscene that they can't even hide their naked bodies! Not only is it embarrassing to even wear them, but a number of embarrassing missions await! They have the most embarrassing experience of their lives, feeling the gazes of men on their protruding breasts and buttocks, and having their bodies washed by male customers... The embarrassed faces of these naive female college students and their well-developed, beautiful bodies are exquisite!
