Tsunade Corrupted

After weeks of living inside of Ino, Black Zetzu had fully taken over her life. With access to her memories, he could perfectly control her behaviors and thoughts effortlessly to the point that Ino's own family did not suspected anything. They even assumed her new physics was simply because of Ino paying extra care for her own beauty. In truth, Ino's body had completed fused with Black Zetzu from the inside, turning her into a semi-immortal being. By manipulating and absorbing any excess chakra around her, Black Zetzu was slowly making Ino stronger just by possessing her. However, he understood that to make Kaguya's dream a reality, she would need not just one person, but an army. And thanks to Ino's abilities, he could become that army for her.

One day, while Ino was competing in a beauty pageant, she overheard some people gossiping aobut Tsunade, the fifth Hokage, was getting irresponsibly drunk alone at a cottage nearly. Sensing an opportunity, Black Zetzu immediately had Ino dropped everything she was doing and rush to Tsunade's last known location while wearing nothing but her bikini. Sure enough, when she arrived, Tsunade had already passed out from drinking. Black Zetzu then had Ino cast a Mind Transfer Clone Jutsu on Tsunade, transftering a small portion of himself into Tsunade's mind and body and then simply left her be without releasing the technique.

Over the next several hours, the little bit of Black Zetzu absorbed Tsunade's vast amount of chakra while slowly corroded her mind away, replacing her thoughts with his own will. Drunk and unconscious, Tsunade was completely helpless as his influence over her thoughts grew steadily. By midnight, he had gained controlled of her movements. To weaken her mind even further and accelerate its corrosion, Black Zetzu then subjected Tsunade to a long and intense session of pleasure. Still drunk and unaware that she had been possessed, Tsunade indulged in playing with her own body for several more hours. She had never felt so good for a long time, and by early morning, had fully assimilated Black Zetzu, becoming his second host.

To reaffirm that he had complete control over her, he took Tsunade's body for a stroll around the empty streets while fully exposing her luxurious bosom. Next, he tossed away her precious necklace belonging to her grandfather. After sensing no resistances from Tsunade throughout either task, Black Zetzu was satisfied with the result and returned Tsunade to her normal life. He used Tsunade to visit the possessed Hinata in secret periodically to please Kaguya's sexual desires and to transfer her chakra into Hinata's body through skin contact, a process that Kaguya was no opposed to.
