I'm an active nurse, but my hobby is survival games! She also enjoys ballet and dancing, and what she wants to do next is... Etch! AV debut! Recently, she seems to be addicted to vaginal training, and her vaginal condition is very good. Serious-chan is the type who wants to investigate thoroughly, who has prepared a perfect pussy for shooting. It's even more thrilling than when you're the enemy's target in a survival game! And when the cock is first inserted into the fake pussy... the tightness is dangerous!
