Once you finally orgasm and let go of your hot load of cum. Typically you spill your babies all over your bitches face and/or breast, chicks dig that shit. Refers to the fact that you are killing thousands of possible babies each time you jack-off or titty-fuck your whore.
The other day, when I was getting head from Taylor, I spilled my babies and she swallowed. But then later she cried about "killing thousands of babies." What a dumb ass.
