Futa No Jutsu

Tsunade's eyes widen as she watches her student, Sakura, struggle against a powerful ninja attacker. She knows that Sakura is no match for the enemy. In a split-second decision, Tsunade taps into a forbidden jutsu hidden deep within her reserves - one that transforms her body into a futa, giving her the forbidden power of both male and female. The power surges through her, but she knows the consequences for using such a dangerous technique. As they continue training, Tsunade can feel the temptation of wanting to use her new giant cock on her students. The jutsu grew stronger and stronger, consuming her mind with its alluring power. But she must resist, for there are those in the village who would never accept such an abomination. As other events unfold, mimicking the events of the anime, Tsunade must constantly battle with herself to keep the forbidden jutsu at bay - all while trying to protect her students from the dangers lurking in their world of Naruto.
