They feel completely at ease because they're with their good friends, but because they're such good friends, they don't want each other to know about their lewd side... This unscrupulous oil massage parlor takes advantage of this psychology of married women. On beds next to each other, separated only by a curtain, two busty wives receive obscene massages, called special treatments. It's amazing to be able to enjoy watching them both writhing in agony while desperately trying to hold back their voices!
