A bullied boy is threatened by school delinquents to invite them into his home. Ryoko, a beautiful mother who doesn't know about such a thing, is delighted that her shy son has made friends and invites them. They took their breath away from Ryoko's splendid body, and that night, they sneaked into Ryoko's bedroom and forcibly raped her as she resisted. It was Ryoko who put up with her wholeheartedly not wanting her son to find out, but the acts of the delinquents escalated further.
