What kind of a man likes to watch someone elses cum dropping a woman's mouth. It's disgusting.
Do you mean to say cumming in a girls mouth? Well there is some fact about that, if a woman consumes a man's sperm they gain youthful complextion because of the semen containing nutrients vitamins/minerals and is made up of part fructose, that keep women young, especially if they are active and eat few meals per day, maybe in their snack time they can take it in the mouth, nice clear sperm all over their face and in and around her mouth that should give her a nice glow too. lol
Side note I wouldn't consume it personally but that's cause I'm a guy and it's detrimental for guys to consume it.
P.S
Oh yeah always make sure you shower first and clean 100% before giving her the load, and if possible eat some healthy foods certain types of food enhance the cum's apparently taste, because then if it tastes nice to the girl, she's gonna want it every single day lol. No more than once per day though unless you just jizz on her face or she spits it out, cause too much of anything is bad for health. So eat clean and in 1 months time your good to go and blow your load.
One last thing make sure the cum is pure white, or clear, any discolouration tell her to spit it out lol. Don't worry I have a PHD in cum dumping.
