Cap-it
To slap your hand on top of your cock when you are ready to blow your load to keep the cum from going everywhere.
I was fucking that chick so hard that if I came inside her it would blow her uterus up, and if I pulled out, it would have sprayed the wall. So did the only thing I could - I had to Cap-it and puddle the giz on her belly.
