To make longer bookings work, IMO, it is essential to have a plan for how you spend the time.
And not to race to get your clothes off.
Talking, undressing, having a drink together --- that sort of thing should all be thought of as part of the session and part of a slow seduction.
Kissing, cuddling, slowly undressing each other...
In a one-hour session, it can easily be 20-30 minutes before you are both naked.
Sensual touching & oral, then takes up about 20 minutes.
Then, you are into the final countdown.
Many of the clients can't get hard enough for penetration (in my 3 decades I have always seen more older clients - they are a dream. Younger ones make life hard work), but even if they aren't hard enough they like to imagine amazing Porn-star sex, so act some cowgirl position and some doggy with one a hand on their little members so they can enjoy the visuals and the fantasy.
With experience, I pretty much have THEIR orgasm timed to perfection. 19 out of 20 men COME within minutes of the time slot I have in my mind.
If it is a 1-hour session, I aim for them to come at 50 minutes. That way, there is a spare 10 minutes if they take longer. Or time for cuddles and a nice chat if they come at exactly 50 minutes.
To make it all work, I find it essential to think of something to like about the client. While they are there, I try not to focus on the annoying things.
There!
Before you know it, an hour is a short session.
