If my wife gives me about three days between sucking me off I will have a LOT bigger load. Also, everyone else is right, her getting me to the edge of cumming two or three times before she finishes me off helps a lot. As an added bonus she likes this because it gives her total control. She can jerk/suck me off, and I wont cum until shes ready. There is some serious feel good anticipation that goes into wondering if she is going to stop sucking this time when I say "fuck baby Im about to cum in your mouth". When she does that, I fucking lose my mind the one time shes starts jerking faster, sucking hard and moaning.. That my friends, makes for a huge load.
