Someone asked if I know what back blowing meant.
I don't have a clue.
Any help here?
Thanks

but a Google search brought up a number of porn movies so I am guessing that it is rubbing your cock against a gal's ass and blowing you was all over her back.

More popularly refered to here as "Italian".

i could be wrong but i think it's when a man get's oral from behind or while he is on top of the female...kinda like a reverse 69(man on top woman on bottom)
