"And come closer to me!" she says, "I want to be able to see how you stroke it!"
You move closer and find it more difficult to control your urges when she is so close.
"Be sure to squeeze and twist a little when your hand gets to the head of your cock!" she says. "It won't feel as good as my pussy would, but that will make it harder on you!"
You follow her suggestion and find yourself gasping and panting as each stroke sends a jolt of pleasure through you.
