Have had similar experiences where it would appear that two pops are available
I've got no chance in an hour especially if they've spent 30-40 mins 'massaging & tossing' & doing this well
If they've got good inglish it just takes some communication to mention what you are & more importantly not capable of
I like things to build to about the 50 min mark for the finale, a very quick shower & then fuck off
On subsequent visits things get easier once they get to 'know' you
With semi regs a couple have mentioned that they are wary of 1st time meets where they ain't sure if the customer is gonna be able to shoot
& don't want to things to over-run get stressy
With the build up & her knob handling talents deffo on the to-do list
Correct on the pricing mate 
It does make more sense money wise but the problem is that she will spend 30-40 minutes massaging and tossing you off, then leaves 15-20 minutes to squeeze another one out. I can’t get over the line with a just a wank with that sort of timing, but if any punters can then it’s thunderbirds are go 
She uses a bit of tit but it’s not a full on cheb-wank
