When he gives a naughty lesson to a bossy female instructor, he discovers her M side.
Kenta is a new employee in a black training program, and he uses his physical strength to handle it without a hitch.

When he is forced to repeat himself, Kenta exclaims, "My strong point is that I have a big penis! Kenta shouts, "My strong point is my big penis! When he looks at the instructor, he turns bright red and is silent...could it be that he is surprisingly naive?
Kenta then returns the favor by giving him his signature cunnilingus.
Despite her strong attitude, the instructor's pussy gets wetter and wetter...
