Two years ago, intrigued by an AW profile for a girl who claimed to be a lifestyle submissive with a high punishment threshold, I booked a hotel room for a two hour meeting. She only did out calls. I suppose it was an act of faith.
She turned up and was everything she claimed in her profile. Great BDSM punt. Paid for two hours but got nearer three!
Since then we've been meeting every six weeks or so, the clock being pretty much ignored. I'd not normally pay the add on cost of an outcall, but this lass offered a fairly specialised service. So I'm happy. Not for everyone, I admit.
