Neither. I don't like the taste or texture, so I suck, play with and lick the shaft and balls when he's just about to cum.
We definitely love it when we tell you we are going to cum and you just keep in sucking. It’s like you are sucking out souls from our bodies through our cock.
I always swallow. When the man is getting close, I use my lips and mouth to increase the pressure on the head as I suck harder. My tongue is going around it, too, so as he cums, I am stimulating that area as much as possible. It is easier to taste his cum right before I swallow and keep my mouth, lips, and tongue in constant motion so his pleasure level stays up there until he finishes.
It’s like when your going down on a woman if she doesn't look like she is being exorcised then your not doing it right
