Cum stacking is the process by which various ejaculatory supplements such as semenoid are used in order enhance a man's cum production. The ultimate goal of any cum stacker is to produce the hardest and largest cumshot possible. Cum stackers will stack various cum supplements in order to achieve the ultimate cum. Thus coins the term "cum stacking".
My cums have been pretty weak recently, so I've started cum stacking.
