DASS-061 Kidnapped by the yakuza, watching her delicate self fall into a week of forced group sex. Sumire Kuramoto

One day, while we were living happily together, a group of yakuza suddenly appeared before us. They said that Sumire was being kept by the yakuza as collateral for a debt and had recently escaped. As we tried to take Sumire and leave, after a scuffle, we ended up getting kidnapped. Then, the yakuza imprisoned us and said with a lewd smile that if Sumire could endure a week of extreme sexual training, they would let both of us go.
