A high-achieving female student is full of curiosity and secretly horny!? She observes her first masturbation viewing as if it were a research subject! When she sometimes forgets her shyness and is absorbed, she is very interested in the throbbing, growing dick! Her big pussy gets soaked with the ASMR-like throbbing sound and the smell of restraint juice dripping from the tip! Because she begs so cutely, I raw-dogged her and creampied her!
