not hard to just say 'hey I'm cumming'...
This thread brings back memories of the most intense oral sex action I've ever had more than a decade ago with JoJo from 5-star. We were in 69 position. The pussy eating got her going, then I stuck my index finger in her arse knuckle deep. She went nuts from that and sucked like a maniac. Then I added my middle finger in there also knuckle deep. She squeeled, moaned and went for broke with the BBBJ. Plus the sight of that round tight little butt of hers skewered on my fingers... Before I could stop her I blew into her mouth.
That was the only time I had a successful CIM... It's a curse, I just cannot make myself CIM no matter how good the BJ is.
I have been on the receiving end of this from a few squirters and copped a faceful or mouthful of girl jizz.
Worst position to cop it in is on your back in a 69er position. It goes straight down your throat.
And no they didn't ask or give a warning, but in their defence usually they didn't expect it themselves and the squirt caught them by surprise too, and they were very embarrassed and apologetic about it.
Agree, warning is the nice thing to do and she can get ready
