371AHSHIRO-175 Yukihi & Shinohara couple/Matsushima & Mizutani couple

Swapping (husband and wife exchange) secretly unfolding in the streets. Here is an abnormal world where you show each other SEX in search of frustration and boredom. Sexual intercourse between a couple of middle-aged couples who change partners with each other burns violently with love and jealousy. Objective mutual SEX appreciation, this is real swapping.
