Ryoko discovers her brother-in-law Yusaku trying to steal her husband's seal. It seems he is trying to make her husband a guarantor for a debt. Ryoko desperately tries to stop him, but ends up being tied up and played with in a lewd manner. He is tortured so much that he even takes her seal. Yusaku disappears, and the debt collector who appears in his place torments him in front of her husband and violates his plump, ripe body.
