Kinda depends. Sometimes you just gotta crank one out before bed to rest better. Other time a good edging for 3-4 hours is great. Sometimes it just goes on and off for a few days till I spill over the edge.
When wife leaves, I get on here and video chat sites and edge for min 12 hours. Then give arsehole a hard fuck with biggest dildo and bend over to shoot HUGE POWERFUL wads on my face!?
My record is like 24 - 30 hours. That was with... Uh...Assistance from my friends Molly and Addie. Usually though, I'm lucky if I find enough time for a half hour.
