Naasuke (japanese Muscle Youtuber)

why do you think so? is it because he is quite famous now?
Nah, just based on his pattern of not really showing anything beyond what he was original willing to, so I have no reason to think he will cross any lines. He's a minor-league muscle Tuber and I think he quit his job? But if he ever plans to return to regular employment he'd be very wary about doing anything that can be construed as porn. Despite the vibrant adult entertainment industry it's still not something you can just do at some point in your life then go back to being a regular "salaryman" (or woman).
