A high school girl feels safe in the kotatsu and unprotectedly opens her legs and exposes her panties. I happened to witness this and played a prank on her while there was someone else around. She is surprised, but can't make a sound, and gradually begins to feel it. And I put her under the kotatsu...










The girls are cute, but if they had used see-through lingerie, it would have been a really great film. The scene inside the kotatsu where she gets her underwear soaked was good, though.
The situation where you can see her panties because they're under a kotatsu is fine, but it makes me wonder if those panties are really worth getting excited over. If you know what I mean by cotton-like (probably) patterned underwear—it lacks any gloss, lace, or embroidery. If you're someone who cares about the lingerie, you might not find this very enticing.
The first girl (Urumi Narumi) is hands down the best. I thought she looked like Rika Mari, and it turns out it was her! She's incredibly cute, and I love the way she tries to hold back her moans.
It was an interesting concept using a kotatsu. The first girl was cute, which was a plus.
Urumi Narumi is cute and the scenario was good. The second and third partners were a bit underwhelming.
