When a girls inner vaginal lips become loose enough for the outer, secondary vaginal lips to
establish themselves as the primary lips of the vagina. Because they have not been stretched before (only the primary lips are stretched during
intercourse) they have an increased tightness compared to the already worn down inner lips. This leads to an
increase in overall tightness, and in turn pleasure/volume of seamen produced by the male.

the double lip grip effect yet? I know you've been wearing
that thang out!
Leo: "Yea man she is just about there. I can feel
the grip gaining strength again!"
Marcus: "LFG!!!!!"
