I know my personal way of doing is not the same as everybody but i want to add to what happened between Julia and Ares.
Honestly if you have not cum when the time is done totally (60min) then you obviously missed your mark. You should never wait for the time to be totally done. I often joke i am a clockwatcher myself as a client because i always look at my time. I make sure i don't get cheated on time, but at the same time i make sure im done way before time is up. I get that this was an incall as its Julia's usual way, so shower time for her was on her time after yours (personally i meet outcall so i always allow 5 to 10 mins for SPs to shower at my hotel room) but even in that case, why wait for the very last second?
It happened in the past a few times i had SPs had an alarm set for 5 to 10m or so before time was up and i was actively masturbating to cum as it started. Alarm was a sign for me to "cmon dude, its now or never" and i came 1-2m after alarm was started. I never like to go that "limit" and when i do its usually because we talked too much at the beginning(20m or so). Wich in a way is a little sad in itself as it mean we have a good chemistry but obviously despite enjoying the provider's compagny, i am there for the sex obviously
Usually if we start after 10 min of chit chat, i usually finish by the 45-50m mark MAX.
I can say without a doubt i never got overtime myself. I had SP leaving my hotel room over time but it was them taking a little more time in the shower and stuff like that. My motto is you should be totally done by the 55 min mark, no matter what. How could Julia know that your "one more min" wouldn't turn out as 5-10 more min. An hour is an hour.
I heard countless stories of clients wanting to fuck for 59 mins of there 1h time, and i just find it weird. Its not because you pay for an hour you should make sure you fuck for all of it... Respect your providers.
Altough being brutally honest may not be "good seller" with your customers , i totally agree with Julia on this. Watch your own time gentlemens !!! I always make sure i do personally.
