This is my first time, so could you please teach me everything? A secret after-school time between a quiet and serious-looking high school girl with glasses and some middle-aged men. The naive and ignorant girl was made to obediently drink the man's saliva as he told her to, and served him by licking his nipples and giving him a blowjob with her immature mouth. At his request, the man stroked her armpits, breasts, legs, ass, pussy... and all over her body, which was a learning experience. She also peed on the man's face for the first time. He was excited, so she bit his nipples and slapped his ass, which made him happy. She had sex with the man at a hotel, licking each other's bodies. The man ejaculated on the girl's face twice, saying, "Your pussy feels good!" A total of 4 chapters.
