Warm saliva and a long, thick tongue. Smooth saliva dripping from the lips. Pressing their lips together, swallowing the tongue, and shaking their hair in a pleasured kiss. Dripping copious amounts of rich, thick saliva, Tsukushi all the way to the back of the gums, and tongue-fucking with the cock deep in the throat. Vacuuming, entangling, making each other drink saliva... a full range of exquisite kissing techniques using long tongues!
