I guess the longest is maybe 2.5 hours. I know I can go so much longer, I just don't ever ever ever have the time!!! I plan to take a vacation alone soon without my wife so I can, as she told me to, "play with myself for as long as I want and have nothing else to do!!" I'm taking her up on it

I can't wait to try like a 4 or 6 hour edge session, wonder if i could last that long?!
When I go for 1 hour it's fucking fantastic, 1.5 it's amazing but there's still the same amount of cum and it doesn't feel much more powerful. I know 2 hours is titanic feeling, I have done 2 hours pretty recently. Man I'd kill for a long session, wish I wasn't so damn busy
