Takeshi's sexual desire is too high, he often uses up two rolls of tissue paper a day just for masturbation. Takeshi's mother is very worried about his future but doesn't know what to do. When confiding in her best friend Shinoda, Shinoda came up with a solution... to let Takeshi have sex with her to satisfy his desires! Just by soothing his desire, Takeshi may return to normal. Since Shinoda used to be a 'queen of promiscuity,' her sexual ability is also high, Takeshi's mother agreed to this solution from her best friend. The two quickly implemented the plan, but they did not expect Takeshi's desire to be so high. He had sex with her and ejaculated inside her countless times, and in the end, Shinoda had to surrender. The first time she failed in front of a man, Shinoda did not give up but decided to conquer this 'sexual monster.' And then, she applied all the 'battle' experiences she had accumulated over the years to 'fight' with Takeshi. And the final result, the winner is Shinoda.
