"Continued: When a female college student was taking selfies at home wearing school swimwear over tights, her younger sister came to visit..."

Furukawa Kei, a university student, had a new fetish awakened in her by her childhood friend Shirasawa Kanako, and she was devoting herself to taking selfies while wearing school swimsuit layered over tights. Then her younger sister, Furukawa Ai, came along…… ※To be blunt, this is a continuation of a short story where a girl was taking selfies in a school swimsuit and tights when her younger sister found out, so she just drags her into the same obsession…… ※While it can be enjoyed as a standalone work (wink wink), you'll probably enjoy it a bit more if you read the version without the "sequel" label first.
