I get the OPs point: why spend valuable paid for punting time trying to pleasure a WG? But like most, I do it because I enjoy doing it; if the girl has an orgasm then I view that as a bonus not a necessity. I would add that RO for me is only an option if the WG has a great, slim body with an inviting fanny otherwise I don't bother and let the girl get on with satisfying me - for which I've paid for!
As for the fake orgasm debate; of course WGs fake it sometimes - I've been told this a few times by different WGs. Also, just like us punters who can cum once, twice, three times in the hour so WGs are all different. I've met some that are absolute nymphos and have no doubts that they cum easily with just about every punter, but I know others who rarely have an orgasm. I had a regular who worked only one day a week and I always tried to be her first appointment of the day, as I do with most of my punts, and she used to stop me from prolonged oral and fingering because she didn't want to cum so early as she found it harder to play the attentive prossie for the rest of the day. I saw her once after she hadn't worked for a fortnight and at the time she didn't have a boyfriend (so she said) and so she was really gagging for it
This particular time, after about 10 minutes, she half-heartedly tried to stop me giving her oral but I could tell she wanted me to continue and so I did. She orgasmed really hard, uncontrolled shaking, legs clamped onto my head, hands pulling my hair etc. When I eventually surfaced she looked serene and content but called me a bastard or something like that!! We eventually fucked like mad teenagers, she cancelled her next appointment (bad girl - we've all been there!!), I fucked her again almost at the two hour point (in a one hour appointment!) then just laid with her for another 30 minutes - I had really fucked up her day! When I called her the following week for my weekly appointment she had already booked me in for her last appointment - no arguments!! And yes, I had an extended appointment and yes she had an orgasm to round off the day
Oh how I miss her, half my age, a tiny size 6 and really good in the sack but she retired from escorting almost two years ago and sadly hasn't been back so she's just a happy memory (probably married with two sprogs by now!).
