Take a deep breath in, then slowly exhale with a long "haa~". The odor of that exhaled breath reaches directly into the partner's nasal cavity, completely pure, without any impurities. As you experience this unique, raw scent over and over, you become obsessed, craving the sensation of a tongue pressing directly against your nose. The tongue presses firmly onto the nose with such intense pressure that it deforms, and right there, it starts getting sucked. Saliva sprays out, and the act of having your nose licked all over feels like a powerful vacuum, producing loud, wet squelching sounds as it's deeply and forcefully pistoned in a hardcore manner.
