Both women have perfectly aligned teeth and a neat, modest appearance, but their tongues and teeth have a slightly yellowish tint, which is somewhat noticeable. Still, this hue only adds to their erotic appeal. Especially Yuna's long, slender tongue seems less like an ordinary tongue and more like a source of endless perverse fantasies. Mizuho's mouth exudes sensuality from every angle—its sucking, clinging quality feels like it could engulf anything. The Medusa-themed atmosphere, combined with their expressions, further heightens the eroticism.
