A journey of immorality with married women. Their lewd natures are revealed at night. They are attacked while asleep and off guard, and are suddenly turned on. The sound of "squish, squish" echoes in the dark Japanese-style room. Their vaginas heat up as their bodies are forcibly touched. Before they know it, the futon is covered in their juices. "Ahh... you can't be so forceful..." these married women say, but they still surrender to the pleasure.
