The first time a girl told me I couldn't come on her face because of makeup, it occurred to me that when I'm slapping my cock and dragging my balls all over her face, followed by passionate kisses...she's had many other cocks and testicles slapped and dragged along her face that haven't been washed off...
As suggested above, I have booked the last appointment of the day, specifically so I could blast them all over the face. Watching a beautiful girl looking up at me and blinking with my spunk drizzled all over her face, it was worth it.
