when a woman is deep throating a man, and he hits her uvula with his cock. this causes her to gag and puke in his dick hole. afterwards, he procedes to fuck her. when he busts, and she creams, the man pulls out as the fluids drip and flow into her ass. the woman then shits in the man's mouth in a swirling motion.
This is the same as the regular soft servedefinition but with a different twist. After you poo in their mouth you ejaculate on the poo and then mix it or twirl it with your penis.
