When a girl is so eager for a man to cum she wants to ceremoniously imbibe it like it’s some kind of precious nectar and she inhales it into her lungs and is lucky if she doesn't end up with Aspiration pneumonia.
Man 1: Dude, that girl last night was very impressive with her cum inhalation skills.
Man 2 :So is your mom..
Man 1 : No.. Your sister can really Cum Inhale.
