I picked up a lost little girl and had my way with her. Since Rion-chan couldn't go home because her dad and mom were away, I offered to look after her at my place until her parents came back. However, her innocent smiles and careless panty flashes—unconscious temptations unique to a young girl—gave me a rock-hard erection. She was such a good girl who listened to everything I said, so I taught her some naughty games, keeping it a secret from her dad and mom.
