I've always said, if the lady is having a good time so will u

I remember a civvie GF who needed "at least" 30 minutes of intercourse to get off, I actually went back to using condoms with her for a while until I could retrain myself to last longer.

 
I had an SB not too long back who actually "liked" hours of virtually non stop action. Best SB I ever had, she never asked for a penny from me, she only wanted two, well actually three things. She liked nice places, she LOVED to be fucked for hours and she didn't want to be "owned" I probably would have married her if it wouldn't have conflicted with "desire number 3" lol (just kidding, no way am I EVER getting married again, no matter how great the sex)

It's funny how many women claim to want a man who can last "for hours" and how few actually like it when they actually find such a man. lol

Unfortunately, she retired and I've not seen or heard from her again.  

We keep on playing and she keeps on cumming, sometimes for 7 or 8 hours. Mouth, cock, fingers, fist, toys. She just keeps on cumming and she is insatiable.  
We usually stop for food.
And she would start right up again, but I am usually ready for sleep by then.

for most providers.  I usually make them cum at least once before I even get started, but most girls can't handle more than a couple times.  It may have something to do with her needing to save something for the rest of the day.  That is why I like to book the last slot because then they are more willing to go as many times as they want (5-6).  Can't say that I've ever been with anyone that could go more than that though, even though I could.
