The original work, "Tondehiniiru" by Etsuyama Yosui, is now live-action with MADONNA's exclusive Maki Tomoda! A nephew is somehow curious about his aunt who has come home to visit at the end of the year. The aunt realizes this and purposely creates an opportunity to tease him, but... It doesn't take long for the two, who have too much free time on their hands, to secretly have a physical relationship. Then, before they know it, the roles are reversed, and she gives in to the young man's desire for his dick, even getting a tan line... The overflowing eroticism of the original work is faithfully reproduced! Plus, original episodes have been added!
