A non-extraction health body spa has opened in a certain mixed-use building in Nish●shuku! It's become a topic of conversation on word-of-mouth reviews. The biggest attraction is that big-breasted girls serve customers in swimsuits. And apparently, the swimsuits are quite revealing... In such a place, my sister unexpectedly appeared!! Seeing my family in such revealing poses made me involuntarily hard, and my sister saw it all. What will she think? What will I do? Just how far will our relationship develop...?
