A traditional Japanese-style inn filled with charm... The scent of a man and woman's secret affairs can be heard there! Love hotels are the go-to place for men and women with a reason to get together, but for middle-aged people with a little extra money, hot spring inns are also an option. This work contains four stories of secret adventures between middle-aged men and women! A day trip without their husbands knowing, a solo trip for men, human relationships within an inn, and more - this is a very exciting work with a dense eroticism that is full of atmosphere!
