BRTH-023 Endure the onslaught of erotic trials! Lewd kunoichi training! / Shizuka

New ninja Shizuka is undergoing rigorous training today! As a ninja, one must not change expression no matter what kind of attack is received. Even if it's an erotic attack, you mustn't feel anything! Even if tickled with feathers or brushes, even if her asshole is played with, or even if her pussy is licked, she must not change her expression at all! That's a ninja! Shizuka has quite excellent grades, but it seems she still needs more training when it comes to being stimulated in the crotch with an electric vibrator...
