After much of my faith in this hobby had been recently restored by a great recent experience, I decided to push out the boundaries and find someone who would offer me a real PSE and picked out Marcela.
External Link/Members OnlyThe Deal - £350 for one hour with full PSE including A level, DFK, OWO and all the add ons.
Location - a very upmarket block in Mayfair. the flat was nice, clearly expensive, the bed - clearly well used.
The Girl - pics looked amazing, on arrival she was taller and larrger than expected and hoped, maybe 175cms, dress size 12 and C / D cup. Facially she was attractive so decided to persevere.
The Service - will keep this short (as it was very short). A shower to start, a gentle lip kiss on arrival, which is how it remained the whole duration, a very quick blow job just on the tip for no more than 30 secs, after which she applied lube for a handjob which she said meant that she could not longer give any more OWO, didn't allow me to touch her boobs (too sensitive), and didn't allow any touching of her pussy. I was still very horny having built up to this all day, and so when sex did commence it didn't last long. I was out of the door 30 mins after I had walked in. Clearly there was no chance of round 2, which I probably didn't want anyway, so had another quick shower and left. So more SOHO walkup experience than PSE.
Taking one for the team certainly didn't pay off for me (or my bank account), but hopefully helps everyone else out.
