A dream collaboration between four of Madonna's busty and glamorous exclusive ladies! ! It was decided that they would go on a three-day, two-night hot spring trip to celebrate the end of a neighborhood event, and when Haneda headed to the meeting place... it turned out that only Yumi, Yuna, Aya, and Mary had shown up, and none of their husbands could make it. Haneda was perplexed, but he spent the time relaxing at the inn alone... A dreamlike three-day, two-night school trip for adults, where sexually frustrated wives come on to him without a moment's rest, milking him continuously! !
