I think these are what you call 'fuck off' prices. Some WGs don't enjoy anal, facials or having themselves filmed while at it, so they quote a high price for the inconvenience. I punted with Sindy once and paid the extra for anal. We didn't get round to trying it until the end of the session, but which time I was getting it up for the fourth time. After a few aborted attempts I just couldn't get it inside her and gave up trying. Most WGs would simply have pocketed the cash for trying, but Sindy offered me a refund for the extra which was actually very kind of her. If she was greedy she would simply have trousered the £30 and had a laugh at my expense.
Probably a year since I've seen Crystal in Harrow. I found her to be very enthusiastic with her extras. Paid 30 for filming, 30 for anal..so £150 in total for a full on hour or so...no rushing at all. Asked her to dress as a secretary, head off the bed face fucking, squirting, happily performing for the camera phone. Got her to hold the camera whilst I licked and fingered her.She basically rode the hell out of me, especially during anal. She initiated most of the session, such as hanging her head off the bed, until I said I needed her ass again and she happily obliged. CIM finish, that she played with and slowly drooled back out for the camera. Can recommend and plan to return one day.
