Scene 3 - Dual Phase ~ (Soukakurou Anal mo Vagina mo Hirogacchaimashita)

Nozomi Asou is not a professional doctor. Don't do what she does, bad things could happen if you do.
You can hear what sounds like drops of water falling down, but it's part of the soundtrack. There are some sound effects that play even if you have sound effects disabled, but I'm convinced that one isn't one of them. The drop is just a beat to add tension.
