Normally, Seto Reika wears pink and girly casual clothes, but let's have her wear a black dress and show us how she's grown into a sexy older sister! She said she started appearing in AV for the money, but the fact that she's still in this industry means she probably hasn't saved up enough yet. It's because of the high cost of living. While listening to her talk, I secretly turned on the camera to capture her panties in the triangle zone and they were lavender! It's even sexier than black lingerie! Ahaaa! I want to know more about Seto Reika!
