"I'm alone with a female girl who works hard at work! My senior girl, 20 years younger than me, shows her panties/close her chest/smoothed gaze, almost explosive!! I thought my erection would be found out and I was getting scolded, but I was a fan of insertion who likes herbivorous old man's dick."

An old man is alone with a female student at a part-time job who is 20 years younger than him. She becomes interested in her shy behavior in skinship, such as looking at her tears when she hears various stories and holding her hand, and begins to seduce her. Despite her confusion, she begins to get aroused by the erection, and comforts the man by touching his dick and making him touch his breasts, and eventually, from kissing him to having sex...
