Twenty young married women, still innocent and naive despite their early marriages. They struggle with their growing sexual desires that they can no longer contain, until an older man steps in to take advantage of their vulnerability! He teaches them everything they need to know about pleasure, pushing their boundaries during their first extramarital affair with no mercy.

経験浅いまま若くして既婚者となった幼さの残る女性20人。ウブで可愛らしい反面、徐々に強くなる性欲に困惑し抑えがきかなくなっているところをおじさんがペロリといただきます！気持ち良いコトをこれでもか！というほどたくさん教え込み、初めての不倫セックスで容赦なくグズグズに調教します。
