Sorry if I'm not using the acronyms correctly, but when I sessioned here in my Claudia report, I got bbbjtc - which I use to mean bare back blow job till cum. Meaning they pull the mouth off just as you cum and then finish the release via hand, tits, whatever body part.
Bbbjtcim is what I thought of as bare back blowjob till cum in mouth - with some girls hanging in there for minutes afterwards, to others just barely letting you finish but no time for afterglow as they're already heading for the bathroom. But essentially, most or all of the release is in the mouth at a minimum, and how much time afterwards she's still prolonging the feeling is completely YMMV with each girl.
I've been able to get this elsewhere, just not at Cielo so far as I know, but again, I'm sure it's YMMV and better service the more you visit.
