Slink is what a girl makes in her pussy when she is horny and ready for fucking. It normally doesn't smell very much, but when the pussy is not washed it can have a fishy/shrimpy sent. This is referred to as sour-slink. Slink does not have any color, unless the girl recently have taken cum in her pussy. Slink has many functions. It protects against infection, attracts males through it's smell and most importantly keeps the pussy lubricated during intercourse.
Contrary to popular belief, a woman does not ejaculate slink at orgasm. Occasionally, she may lose bladder control and squirt some urine.
My God, Katie was so wet, my penis is still covered in slink
