Sorry you had such a disappointing encounter. It's quite unusual these days to find girls in the SB who are that clueless about sex. It's surprising. Generally speaking I find the youngest ones to be impressively in tune with their bodies, their desires, and their eagerness to please. Oh well, on to the nest!
That has all the markings of a cheap car date, only it wasn't in a car.
I rarely agree to meet for BCD without a M&G first, usually set up without a BCD date scheduled yet. During the M&G I will ask/discuss, among other things, what her sexual comfort level is what her limits are for various activities. I tell her I love oral, giving and getting. If her response is less than enthusiastic, I dig a bit deeper to see why.
I recall a M&G several years ago with an early 30's Asian Real Estate agent. She was new to the bowl, after a recent breakup with a long-term BF. During our chat, she mentions she was dealing with some past sexual trauma and when she started dating the BF she was only comfortable with lying on her back while he penetrated her in missionary. She never gave the guy oral, never wanted it from him, and was not interested in any other positions or acts. I let her down gently, but firmly. I explained that I was not willing to agree to her restrictions and that I thought she would have an extremely difficult time finding any other SD who would as well. If I hadn't gone through that discussion with her, I might have ended up wasting north of $1,000 on allowance and date expenses before I found out she was effectively a starfish, even if due to the heinous acts of her past abuser.
Still, I have also had my share of performance disappointments. Perhaps in my younger days, I could just get hard and stick it in any hole to get off. But now? Now I need BCD time to be a participation activity.
I think I agree with earlier responses. She is likely a (rather lousy) hooker who is trying to drum up new business without walking the local strip or advertising on ListCrawler.

This is why careful vetting and a separate day M&G is essential to establish what you are both looking for and to avoid disappointments. Communication about sexual expectations during the M&G or prior to BCD, as Herb has pointed out, is the key to avoiding this situation in the future. While it's not foolproof and you may still get a bum steer, at least you'll have mitigated your failure rate and increased your success rate in finding a compatible SB.
She briefly took it in her mouth but not enough to get my full attention.
