In my 20's and 30's I shot many of my own cum loads into my mouth to enjoy while jerking off. Not as flexible or shoot as powerful now at 59.
I have done it on purpose a few times, trying to hit my mouth, but it's also happened a lot by accident, though it's gotten less. Always enjoy it though.
Of course, And like most - instantly regret it the second I cum.... until someday again when the horny brain is fully in charge, and I do it again
