It certainly wasn't the one who, when I asked her to talk dirty, replied:
"Fuck me harder, innit"
One of the best was a civvy at a swingers club who, once I was inside her, gasped:
"I don't think you realise how massive you are"
She was a heavy squirter and literally drenched the sheets, BTW
I've also had a prossie stop me in mid-flow to tell me she had never heard any guy talk such a constant stream of filth during sex.
I took it as a compliment.
