Went with Ivanka/Ivana who appears on a number of different websites. Booked through Barracuda @ 200 for the hour.
External Link/Members OnlySuffice it to say, she was not as attractive as her photos, but was reasonable. However, despite having pre-agreed OWO, she cancelled about 5 minutes through and we then proceeded to spend the next 20-30 minutes on the phone with the agency.
I got 100 back, and couldn't get more. 100 quid for 5 minutes of blowjob is not a good deal and I will not be using this agency again. They were difficult and not accommodating at all.
Beware this agency in future
