Embarrassing Exposure Hot Springs Trip with My Son’s Classmate, a relentless punishment focused on the nipples. Of course, it’s a secret from both of our parents.

I brought Mana-chan to my secret base. It's just an abandoned house in the mountains (lol), but the weather was nice, so we played tricks outside. Mana-chan, she was so shy and worried that someone would come, which was so adorable. She is small and delicate, yet her nipples are long, sensitive, and responsive. That's obscene. It's a secret between the two of us.
