◆The Maruyama couple and the Sugawara couple have their first swapping experience. A fixed-point observation of how two couples who met for the first time lived a super-rich cohabitation under one roof. Ryoko who participated in doing anything for her husband, but she is already crazy about other people's husband's cock. Hiroshi Sugawara & Natsu, who are also swapping for the first time. Two people with strong libido greedily devour the body. The last of the swapping life of 3 days and 2 nights is a super rich 4P big orgy!
