In a way, I'm glad that you don't waste that precious stuff. Cum shouldn't be wasted, but celebrated and enjoyed.
Women who spit tend to bother me. If I cum on a woman's mouth, I'd expect her to swallow what goes in her mouth then lick her lips and mop the rest up with her finger and lick that too. Then clean the dribbles off my cock as a final act of respect for the cum.
I'm trying to get my wife to drink my cum from a condom after I fuck her in the ass. Instead of wasting it in her ass, I'll wear a condom to harvest my load then remove it off my cock and pour it all over her mouth to enjoy.
What do you think of that idea ?
Another idea would be to save the loaded condom, then wait till I'm hard again, have her suck my cock and while she sucks I'll pour my cum out all over her mouth for added flavour, then blow a fresh load all over her cum soaked mouth again. Nice
