I used to do it becauase my ex-bf would love it, it turns him on to watch me lick his fingers clean.
As for swallowing, its not exactly the most best tasting thing in the world, but my ex-bf used to love it, I think we both watch
waaaaaaaaaaaaaaaaay too much porn, and sometimes I like to emulate the porn actresses and use all their hot moves, it kind of
rubs off on me

And I know he gets a lot of his moves
from watching porn too
I used to think it was kind of degrading to have someone shoot his load all over your face, but it's all in good clean fun so i suppose its allright as long as it's with someone I love and trust.
