This very much depends.
It depends on if I’ve seen the lady before or not.
I never do half hour or 90 mins for the first visit.
I can/ will eat coochie for 20 mins+ so 1/2 hour visits don’t make sense.
An hour lets me know if she is good at her work or just going through the motions.
If they are good the next visit will be 90 mins (or more).
For certain massage sessions 90 mins is my preference. It can be a rush to get 2 rounds out in 60 but it’s more pleasurable with 90.
Booking 90 only to find out there’s no connection or chemistry makes for an awkward situation or less than economical, I’ve walked on a 90 min session at the 45 min mark because of good advertising and poor delivery (thinking with the small head).
There are two ladies that I have seen, one regularly that if we are having fun will extend to 90, if their schedule allows for it. One lady knows with me that if she’s a good girl that I bring the extra half hour. Sometimes she works to get the extra, sometimes it seems like she doesn’t care, sometimes she gets 2 out of me in the hour and sometimes I tell her at booking that I’m gonna need 90 mins.
So it depends, on my mood, how horny I am, her schedule, her mood, my budget at the time, her level of previously demonstrated service, my energy level, my schedule and if she has a lickable pussy or not.
