We received an email from Shizune, a married woman living in Aomori, wanting to appear in the film, so we contacted her remotely. With no nighttime sex with her indifferent husband, her frustration has reached its limit and she is on the verge of exploding! She wanted to appear in the film, but was afraid of being found out, so we decided to proceed with the filming on the condition that she wear a mask. At first Shizune was shy, but when the actor attacked her hard, she turned into a masochistic married woman who moaned and shook her impressive L-cup breasts. Then, in the last segment, her true face was revealed!
