Minami has a strong libido, but is frustrated with her husband's single assignment. One day, his son's friend Kousuke comes to visit and his eyes are caught by her defenseless appearance. When Minami notices this, she casually invites him over for a snack, but... Then, he continues to be squid countless times because he doesn't know that he won't wither no matter how many times he ejaculates. With that as a boundary, when I let Kousuke visit me many times a day, my body could not endure the pleasure.
