Seira, a modern college girl, is 146cm tall! With her super-minimal body, even a tiny diaper would fit in there! A huge amount of pee overflows from her saggy diaper! She desperately resists pushing the camera away in a super embarrassing scene! She screams out "I'm embarrassed!" when forced to wear baby clothes and play baby! Such a pure reaction is irresistible, the extreme shame of a real amateur girl who is seriously embarrassed! A DM arrived on a certain x-marked SNS. It was a contact requesting an appearance. The sender was Seira (pseudonym), who attends a certain university in Tokyo. She is interested in diapers, but she has never had any experience with them. Seira herself is a modern college girl with a light-hearted attitude. She was persuaded by her to proceed with the shoot, but wait a minute! This is her first shoot?! It would be a waste to do things the usual way, so we decided to let them try out various things while we were there, and we started filming...but it turns out our (Sanwa) common sense is wrong...?! Their cheerful attitude suddenly changes! A pure, innocent, and cute documentary about their first diaper experience.
