Sweet Saliva
A fetish in which one inserts something high in sugar in their mouth and allow it to dissolve before proceeding to drool or actively eject its broken down remains onto their partner and watch it run off their body or simply just stick there until it eventually becomes absorbed by or stick to their skin.
"I took a big swig from a gallon of fruit punch in which I drowned enough sour patch kids to induce a diabetic coma and then that's when I dumped that huge load of sweet saliva on my dear Delilah."
