I'm sure this has been discussed before, but I don't recall it anytime recently. That plus I'm too lazy to search, lol.
If you book a full hour with someone, why wouldn't that automatically be MSOG? What would be the point of doing a full hour if you might pop at the 30 minute mark? IMO, if someone pays for a full hour, they should get a full hour worth of fun. You shouldn't get booted out the door if you pop once before that hour session is over. I mention this because there was a provider recently that offered a full hour, or a half hour. Once MSOG was off the menu, I figured I could get mine in 30 minutes and be done.
But usually after all that hot, sexy and sensual four play build up that when you do get around to exploding you usually are so totally drained that the thought of a second pop would be wonderful and we will or can try but it usually doesn't happen.
