Cum-smacking 

The moment when you are balls-deep and at the last second, you pull out, jizz into your hand, and slap her across the face with it.

She is totally into cum-smacking when she has a drink or two.
She asked me to be rough, so I cum-smacked her.

Cum stacking

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.

Cumstacking 

Use of ancient wisdom, herbs, chemicals, any means necessary to build monstrous quantities of ejaculate ( cum ) to blam all up in, or spackle onto, a partner.

I was cumstacking for a week and when I spackled my gift on her, she wept in gratitude.

Putting on and jerking off into someone else's used condoms.

Kalvin took his roommates used condom and started a cumstacking chain by putting it on himself and jerking off into it for the next person.
