No story for this. I wanted a more "seiso" (kinda) piece of Un, and the direction went a teeny bit different, mainly because I am unsure of how much Coco can pick up cute without being lewd or degen despite the attire shown. Yes, I even showed a specific pair of cute hibiscus undies as a visual reference for the pattern, because I think its cute.
Nude variation will soon be on Paheal. (Maybe a future AND separate Pixiv for my censored paid lewds.)
