Satomiko who listens to her son peeking at the masturbation while feeling the pleasure of jealousy. The excited son gives the hard-founded meat sticks to Mumiko, and then he hits her with an unbearable libido. After touching the heat of the skeletal stick, which has overlaid her lips and erected it, Mumiko goes beyond the relationship between her mother and child and falls into a swamp of incest.
