I don't give a facial everytime, but do like to ask from time to time. Girls I've been with for a while know what to expect. New girls are always fun. Once I get the go ahead I usually like to do it while straddling the girl. Used to do it with them on their knees after a blowjob but didn't get the full coverage I wanted from aiming issues and her moving lol. Like to have them lick and suck my balls when I'm about ready. Also a word of advice, when you go to straddle make sure arms are under legs and I grab an extra pillow and use it to prop their head up and make them comfortable. This way when you ejaculate you can easily aim your penis at her face and let go of the full load without her laying back and covering the wall instead lol.
