My nephew Shinya is staying at my house near his school to take his university entrance exams. I sometimes help him with his studies, hoping that it will help him, but one day he seemed fidgety and restless. I was curious and asked him what was wrong, but he just hid his crotch in embarrassment. When I removed his arm, his penis was erect. It had been a while since I had seen such an erect penis, and my body was hot and tingling... Auntie will also teach you naughty things.
