She finally started to stroke me, very gently and very slowly. In my current state, however, it was less than a minute before I was on the verge of cumming. Lisa was already going so light and slow that she could only stop completely in order to keep me from cumming.
"Wow Peter, I'm not sure I can make this last nearly as long as I want. I'm even afraid to touch your balls, they look so big and full I think they might just explode," she giggled. I've often mentioned that I've never been able to cum from ball stimulation alone. But Lisa had never teased me to this point before. She was obviously afraid that in this condition I might actually shoot just from that.
"I just am not willing to have this end just yet. I know just the thing" and with that she jumped off the bed and ran into the bathroom. In only a minute she was back with what looked like a tube of lube. I knew it would feel great and was also sure that no amount of friction reduction would matter. As soon as she started to stroke me again I was positive I'd explode. And I was ready.
Lisa crawled back up on the bed and knelt between my legs again. She squeezed some of the lube in her palms and set the tube aside. She rubbed her palms together for a few seconds and with an evil grin on her face she reached for my cock and said, "Okay, here goes baby. I'm not stopping this time until you cum. But I think it might still take a while."
No way! I was positive I'd be cumming in seconds.
Again she started to very lightly and slowly stroke my cock. The lube felt cool. In a few seconds it felt very cool, like it had menthol or something in it. Very shortly my cock felt not only cool, but almost tingly. Not unpleasant at all, just different than normal. Lisa was stroking a bit more firmly and just a little bit faster. To my amazement, conversely the sensation was less than when she started out very lightly. Her grin widened and so did my eyes I'm sure.
"What kind of lubricant is that?" I almost croaked.
"Oh, its something new I picked up" she giggled, "like it?"
"Actually it seems to reduce the sensation of what you're doing, why?"
"Well, that's probably because its called, 'Prolong', it has a desensitizing agent in it" by now she was laughing. "The saleswoman guaranteed that it would prolong an orgasm regardless of the man's state. I guess this will be a real test, don't you think?"
"Lisa, baby, PLEASE, I need to cum. Make me cum, please. You ..."
"Shhh" she cut me off "just relax. I said I wasn't going to stop until you came and I'm not. Now lie back and enjoy, I know you want this to be good and it will. You earned it the last few days."
And she firmly and steadily stroked me using both hands. She rubbed my balls with the heel of her right hand while it stroked most of my shaft and her left hand steadily stoked and played with the head of my cock. Every other stroke she would twist her wrist as if turning a doorknob.
You can't imagine the frustration of this treatment unless its been done to you. It is very much a head game, but there is also the physical aspect. You can see and feel your cock being stroked in a way that should have you shooting cum all over the place, even without the build up I'd had. And there is definitely stimulation, it's just that the nerves aren't working right and you just don't cum. You feel right on the edge, and you know that the stroking should make you cum, but you just don't. Both the sensation and the frustration are unbelievable.
This went on for quite a while (as is her way, Lisa had the clock turned so I couldn't tell for sure how much time had gone by) when she reached for another tube of lube.
"Lisa, no more please I..."
"Shh, I said! This is regular lube, it will dilute the 'Prolong' and the nerves in your cock will slowly return to normal. You'll be cumming hard in no time! Or do you want me to put some more 'Prolong' on to make it last?" she giggled as she set the lube back down and picked up the 'Prolong'.
