   Summary

   It does not matter that Tsukasa possesses God-Tier levels of strength; that he could—had—broken Senku with his bare hands. Tsukasa has sworn an oath of utter devotion to him, and with one simple word Senku could start or stop any of Tsukasa’s advances. It’s an intoxicating power, and what kind of scientist would he be if he did not take advantage of it for the sake of some experiments?

   OR; Senku tops Tsukasa using the power of sex toys.
