The setting for this latest installment of the popular "Get the Auntie Excited" series is a hot spring inn. Seven mommy friends and a college student meet on a trip, and in addition to the sense of freedom they feel on the road, they play King's Game with some alcohol, leading to a wild battle with some bold orders. The men and women then become close, and meet up in secret at the hot springs and behind the building. The college student is enthralled by the aunt's generosity, and the aunt is so excited by the touch of a young man that she can't contain herself, even having sex!
