Amy did as Mary had directed, after a few minutes she started again and shortly after that she told Mary she thought she needed to stop.
"Okay, now watch closely, first you're right about one thing, after what you've put this man through he can't last too long at one time. But you could have slowed down sooner and it would have taken longer to get to the trigger point. Also, you don't know all the signs well enough yet, but he could get quite a bit closer and not cum. Watch."
As Mary was talking she had placed her right hand under Bill's dick and was holding it up while she very gently and very, very slowly slid her left hand lightly up and down the upper side of his shaft. Bill was moaning constantly and nearly squirting precum, but he wasn't cumming yet.
"Watch his balls Amy, see how they are still sucking up into his scrotum. As long as they are going higher and higher he won't cum." Mary kept the almost nonexistent stimulation going, "Watch close now, his balls are all the way up and watch his cock, its about to start to spasm now. There it is, now we stop."
Bill was going crazy. He'd been squirming and thrusting but Mary was so skilled that she was able to totally control the amount of stimulation in spite of Bill's efforts.
"See how much longer I was able to keep that up, and see how much closer he got. Now watch this, by rubbing his balls like this, I can keep him right at the edge for a prolonged time."
"God, oh God, oh my GOD, oh, oh, oh, ahhh" Bill was babbling. If he thought Amy had been a tease he'd just discovered that she was a rank amateur compared to Mary. Never in his life had Bill been so close to an orgasm without cumming. He wouldn't have believed it was possible. And she was keeping him right there, but not putting him over. The ache in his nuts was almost unbearable. He had never needed to cum anywhere near this much.
"Here is something else, but you have to be really careful with this one. Watch how I very gently run my single fingertip around the corona of his glans. This drives them totally nuts" she explained as she ran her fingertip so lightly around the very ridge of Bill's cock head.
Bill couldn't believe the sensations, it felt as if his whole groin region was on fire, yet he could not cum. Finally he was going to cum. He felt the contractions start and instantly Mary stopped. His cock contracted one time and a dribble of cum came out the end of his cock and then, NOTHING. His orgasm had actually started for just an instant, but stopped immediately as Mary did.
"WOW! That was amazing! Can you teach me how to do that?" Amy squealed.
"Sure, in no time at all. Again, see how close he was and long he was there?"
Bill was quietly moaning, but had stopped talking.
"You know Amy, I think you may have found a perfect subject. I think Bill is a true submissive, and actually likes this. I'm amazed that he isn't begging and pleading to cum. For me, hearing the desperation in a man's voice is a huge turn on."
Amy started to laugh. "What's so funny?" asked Mary, rather confused.
Amy told Mary about her 'deal' with Bill. Mary started to laugh too. "My God Amy, you are one wicked little bitch. You're going to love nursing! I can see you are going to make a lot of balls ache in your time" Mary continued laughing.
She got more serious though and said, "But Amy, cock teasing in the hospital is one thing, seeing patients outside of that is really not a very good idea. I can't tell you what to do, but I'd really encourage you not to."
"But I promised him that if he didn't ask to cum again today I would. I won't break my promise."
"That's understandable, and good of you. Besides, I imagine you want to know what having that monster inside you would feel like, huh?" she laughed. "If I didn't have an absolute personal rule about it, I might want to as well. Oh well!" Then she leaned over and whispered to Amy so Bill couldn't hear "Amy, I promise I can make him beg to cum in the next fifteen minutes. You'll be off the hook, and if you then choose to still fuck him, well that's up to you, but you'll be able to get him to do ANYTHING for it because you won't have to without breaking your promise, right?"
Amy's face burst into a huge grin as she whispered back "I'd owe you a big favor if you can do it."
"Oh, I can" this she said loud enough for Bill to hear, but he didn't know what she was talking about.
Mary waited about five more minutes and then started again. Bill was still rock hard, but had recovered enough for her to make this one last longer than Bill could stand. For the first time Mary actually spoke to Bill as she took his balls in one hand each. "Bill, you have the best cock and balls I've ever seen, and I've seen a few. Your balls are so full that I can scarcely believe it, you must need to cum in an extreme way. This little Amy girl is rather amazing wouldn't you say?"
Bill was moaning again, but looked into Mary's pretty face and finally spoke back, "Oh, she's that and plenty more, and you are quite the bitch yourself!" He smiled as he said it, he thought Mary was quite sexy and he knew Mary was basically correct. Bill was desperate to cum and he really wanted relief and for this to end, but there was part of it that was incredibly exciting to him anyway.
"Why thank you!" Mary giggled as she started to stoke Bill again. This time far more slowly than Amy had. After just a few strokes she said "I know, this will make it feel even better." And she took the massage lubricant from the bedside table and poured a generous amount in her hands and lightly rubbed her hands together. Then she wrapped both hands around Bills cock and started to slowly pump again, holding his cock very loosely between her two fists.
"Does that feel good Bill?" Mary asked, trying to get Bill talking.
Bill sighed deeply, "Yes Mary it feels very good."
"I'm glad, I want it to feel good. It will feel even better soon, here let me show you." And she held his cock a bit tighter. She lengthened her strokes too, so that the heel of her left hand rubbed his balls at the bottom of each stroke and the fingers of her right hand slid over and around his glans at the top of each stoke. "That's even better isn't it Bill?" she went on, keeping him talking.
"Oh God yes, that feels wonderful Mary." Bill didn't realize it, but he was about to lose it.
Mary kept up the pattern, but once again loosened her grip and slowed her pace. Bill moaned. "What's the matter Bill, hmm?" she giggled.
Bill just moaned some more, he still had enough control not to ask to cum, he knew it wouldn't matter anyway. Mary realized she had a tough customer here and upped the ante. "Amy, you start to massage his balls like I showed you at the end of the last cycle and I'll just keep this up for a while longer. I think he likes it! You do like it don't you Bill?"
Bill was still moaning, but managed a "Yes I do like it, ohhh" the final exclamation just as Amy started on his balls.
Mary stopped stroking his cock and started working on his plump head, turning it like a doorknob.
"Feels good doesn't it Bill?"
"Oh God yes, please"
"Please what Bill?"
Bill just moaned pitifully.
Mary was really tormenting the head of his cock now. Holding his corona between her thumb and forefinger on each side and slowly rubbing it from front to back until her hands met, then back the other way. Over and over and over.
"Bill, you must be so very, very close. A stoke or two would do it, wouldn't it?" Mary asked in that soft nurse voice.
"Mmmm, oh, mmm... mmm" Bill was incoherent.
"Here Bill, let me show you" with that Mary gave Bill's throbbing cock two long, slow stokes. "Want more of that Bill?"
He was gone now "Oh yes, please yes!"
"Okay, here is one more" Mary stroked him firmly, but oh so very, very slow. From head to balls and back.
Bill groaned so much that Mary actually laughed again. "Feel good Bill?"
"Oh God yes!"
"Bill, a couple of more stokes and you're there! Do you want that?"
"Yes, Please Mary!"
"Please what Bill?" Mary teased.
