Did it twice in a 30 min appointment once. But at the time my nads were producing a huge amount of sperm and both loads were quite large when shot. But like I said it only happen once in all the 30 min appointments I've had. I believe in was with Dita Irish. Her bum just made me blow it the first time while in doggy. Then later I finished with CIM. It was a substantial load. Great time had by all. She loved it.
