Miyuki was defenseless on the train, thinking that being over 60 years old, she would be safe. But the movement of the hand caressing her buttocks was clearly no accident. Surely... I was being targeted!? The moment she realized this, fear ran through her and her body stiffened. Unable to resist, Miyuki was brought to orgasm. A few days had passed since then. That incident should have been a nightmare. But the memory kept coming back to Miyuki, making her body hot. Soon, a desire to ride that train again began to well up inside her.
