In recent times, the Asahi-Gumi yakuza organization has fallen on hard times after their boss falls ill, leaving it's higher ups scrambling to find a solution to their dwindling membership. This, as it struggle to stay alive and prosper. Aniki, has come to Ichiro for advice. Unfortunately however, both of them are not sure about what the organization's next move shall be. Aniki leaves Ichiro to ponder this, as he leaves to consult the rival Kanto yakuza. Unfortunately, it is a meeting that proves deadly, when Aniki's body turns up in the ocean a short time later. Of course, it's an event which leaves Ichiro with a decision resting squarely upon his shoulders. He is left with no other choice but to do what he was strongly against, and that is to join up with an outside organization. He chooses the foreign mafia. He then meets up with the head of the foreign mafia, Tony. But before the meeting can get underway, the two men find themselves interrupted by the female boss of Asahi-Gumi, Mina Asahi, and she is not pleased. It is then that she first learns of Aniki's tragic demise, as well as the incoming partnership. She is really angry at Ichiro for not first informing she of the important details. However, she meets with Tony, and she soon agrees to enter into the partnership. But first, the group must enter into a blood oath, one that is began with the two parties drinking a cocktail known as "Sakazuki". With the oath now made, Mina makes a decision that is rather startling to Ichiro. She wants to make a family bond with the organization as well, and the only way to do that is through the act of sex. Ichiro is hesitant as Tony is a black guy. But Mina assures him that she is more than capable of taking a big cock. It is the start of an interracial threesome. During which, Mina experiences double penetration, and in the end, she leaves with both of her holes filled with cum!
