Holding his cock in one of my hands, I pressed down the skin, uncovering the top completely, then pulled the skin up again, repeating the operation with absorbed interest.

"You had better not do that;" said Bob; "unless you want to make me, come"

"What do you mean?" I asked; "I don't understand."

"Don't you know?" he replied; "that is the way to make spunk. What babies are made from, you know."

I stared at him in great surprise. I was evidently on the brink of momentous discoveries, but scarcely knew whether to believe him or not; yet he seemed perfectly sincere as he met my look.

"You don't know anything about these things, I can tell," he exclaimed with a low laugh. "Would you like to see, then?"

I answered in the affirmative, so he sat close to my side, and told me to keep moving his cock up and down as I had been doing before, I did so, and he lay half back on the pillow, his legs slightly apart; and evidently full of enjoyment.

I kept on with my task, too absorbed with interest and excitement to say anything, and watching eagerly to see what the result would be.

"Don't stop," he whispered hoarsely, as I relaxed for a minute. "It won't be long now. Go a little faster."

I complied, and after another interval he exclaimed, "Go slowly now. It's coming!"

I rubbed Very gently.

"Hold it tighter," he continued; "and don't let go until I tell you." I took a firmer grasp, as directed, and went on with a slow measured movement, uncovering the top of his cock fully each time I pressed downwards. Presently he straightened his legs out and pressed further back on the pillow; his belly heaved, I felt his cock increase in stiffness and give two or three big throbs, then out spurted some whitish liquid; shooting up into the air and falling back on to his body, while a quantity followed with less force and ran over my fingers and the back of my hand. I kept on rubbing, but in a few moments, Bob told me to stop, and I bent over to see the new and strange sight, while he leaned down and picked up a handkerchief. When he had got this he bade me let go; and I did so, when he proceeded to wipe himself and then dried my hand.
