JAV Tokyo

They fell in love, got married...and after five years of married life, their relationship had become stuck in a rut and they had no sex. Jun, a simple and serious husband, was in agony because his wife refused to have sex with him and he was too shy to go to the sex industry. One day, his wife decided to go home for three days for a friend's wedding. Worried about the housework in her absence, my wife's sister, Saki, came over with side dishes. The frustrated married sister-in-law seduces young Jun, who has a pent up libido, "You guys don't have sex anymore even though you are young...oh my, we don't have sex either...". While his wife (sister) is away, the two devour each other's bodies... Jun is not cheating on his wife, but he is still her brother-in-law.
