Yes, cannot remember her name as it was a few years ago via an agency. I do remember the exact details though, she looked like Mercedes from Holyoaks (years ago when she was really fit). Anyway arrived at the location buzzed to get in but she didn't know how to work the entry system. After the agency called her I was finally let in, she was extremely apologetic and explained I was first client on her first day, as you say it is the holy grail, so I was over the moon.
Paid money over and stripped off, in she came with the normal lingerie, stockings etc. I started by dfk her whilst she was against the wall, soon took off her bra and had a good grope. She then removed her g string and opened her legs wide, I then asked if i could finger her, which she agreed. Started off with just a couple, but she was wet and I ended up with all four fingers up her, really horny. I then said I wanted a BJ without and I lay on the bed. Her technique was great, one of the best I have had. Shot my load, which she swallowed.
Only time I have had 4 fingers up an SP and I think it was mainly to it being her first time. I think she only lasted a few days, but she was good.
