Childhood friends plan [swapping] to exchange wives with each other in order to get rid of the rut. "My daughter-in-law is being squid with his cock... Gokuri" Feeling like a netorare when a loved one is squid with another person's stick! "I'll Give His Wife A Creampie!" ] Netri feeling trying to conceive next to her! An unusual space where contradictory and complex emotions are mixed! Wives who are at the mercy of the exchange game set up by their husbands and are confused but drowning in exchange sexual intercourse ... A record of 4 days of crazy iku.
