If after you've cum she expects you to piss off and leave regardless of the time then this is classic bad service. However in my old age I can no longer cum twice in an hour. Sometimes I've all on cumming once! I've always, even when younger, taken a while to ejaculate, although I did used to cum twice sometimes in the hour. Remember Kelly at Bunty's Manchester getting me to cum twice in about half an hour once, and that wasn't that long ago!
I have seen many girls who have the attitude that once you've orgasmed it's up and out, and as I say this is classic bad service if you have some time left. I've also had the classic 'Hurry up, you only have ten minutes left,' said to me a couple of times when I've been struggling to cum, another classic example of poor attitude and what not to say to a punter. If he's struggling to cum, then that certainy isn't going to help.
If I've cum, I'm often more than willing to leave early these days, of course this depends very much on the attitude of the girl.
I have used Supreme 69 agency twice. The second one I have a auto-censored FR for, and this was a classic case of my leaving early as the girl wasn't particularly sociable, whereas on the previous experience, the girl, Karina, was insatiable, and I think I'd already cum twice when she tried to make me stay for a third round. We had run well over times and there was no extra charge. She must have been enjoying herself!
I also used to have overnighters with a truly exceptional girl with no clock wateching for just £350. Therre was none of this strictly 8/9pm - 7am business. I used to pick her up about 8 and, as she was dependent upon my transport to take her home, she usually didn't leave until about 10 next morning. That's what I call an overnighter!
As I say she was exceptional though.
Amy, who I've seen more than any other wg, has the balance off perfectly. She never allows you to stay a few minutes over, but never cuts you short; she never clock watches but has an inbuilt radar and your leaving always seem natural. Nicoletta is the same, although does seem happier to run overtime when chatting.
I think getting a client to leave on time, but in an appropriate manner, is one of the great skills of being a good wg and isn't easy to acquire.
As a client I would never try to take advantage and take too much time I hadn't paid for, although 5/10 minutes shouldn't be a problem; when I've had outcalls girls are frequently late anyway. I have often paid or offered to pay for any extra time beyond that I've taken.
The last girl I saw, Nicole in Sheffield, was happy for a chat and a chill out even though I had taken a long time to cum and we had reached the time. In fact she insisted I relax a bit as I was knackered. I thought this was a nice touch and it's something clients remember, just as they equally remember the 'hurry up, you only have ten minutes left' scenerio - the two times it's happened to me, I recall vividly, although I perhaps shouldn't complain too much about the second one as the punt had been paid for me! The only time I've had a free punt!
Although the first was with a well known Nottingham 'courtesan' who I thought would have had too much 'class' to say this.
Ultimately it all comes down to both parties being sensible and respecting each other, as does much in this business. Men who try to blatantly take advantage by attempting to take up too much time they haven't paid for are as contemptible as women who want you to piss off after you've cum even if there's half an hour left.
