OK so I'm biased but for me, the best part of all giving a BJ is getting him spurting/flooding in my mouth and not wasting a drop of it. It must be played with and swallowed, or if there is too much, straight down the hatch and used for energy. Your body will be running on calories from cum
I have a friend who I would jerk off in to a shot glass ,he would fill it, then I would savor it and swallow. Also liked to feel his swollen cockhead jerking and spurting in my mouth and licking his big loads from my wife's hairy pussy and asshole. Her pussy ( pictured) is wet and tight and usually can coax a big load out. I like to catch it if they will pull out for me! My wife and her friends love that I'm such a cumslut!
I've eaten my own cum for years now but never had another guy shoot his load in my mouth so I can taste and feed on it. I've been fantasizing and craving for it. Always wanted to be fucking my gf or ole lady and be sucking on another man's cock and have him shoot his load all over both of our faces and into my mouth so I can show it to my gf as I'm swallowing it
