Takeshi's libido was so high that he used up two rolls of tissues a day just to masturbate. Takeshi's mother was worried about his future but didn't know what to do. Sitting and confiding in his best friend Shinoda, Shinoda came up with a solution, which was... let Takeshi fuck her to her heart's content! As long as he calmed down his desires, perhaps Takeshi would return to normal. Since Shinoda used to be a "lewd queen", her sexual ability was also very high, and Takeshi's mother immediately agreed to this solution of her best friend. The two quickly carried out the plan, but they didn't expect Takeshi's desire to be so high. He fucked her and cummed inside her countless times, until Shinoda finally surrendered. Defeated by a man for the first time, Shinoda did not give up but decided to conquer this "sex monster". And after that, she used all her experience of "fighting" for many years to "fight" with Takeshi. And the final result, the winner was Shinoda.
