In the following months David and Mary's sex life was very active. That is to say, he was unlocked, teased and edged to the brink of orgasm many times a week but rarely allowed to cum. Mary, of course, came many times in each session, mostly from his oral attentions, and especially during her "time of the month".
The most challenging for David was when he was allowed to enter her pussy but not allowed to cum. The penalty for cumming without permission while in Mary's vagina was 24 cane strokes, twice as many as cumming without permission during edging. Not only was the punishment a fine incentive for developing stamina, but the edging practice actually was helping him enjoy the arousal plateau and not rush to orgasm.
For her part Mary was also learning the subtle signs that David was close to cumming and how small reductions in her stimulation of him could hold him back from crossing the line. As grueling as the edging sessions were for him, David was beginning to see that her strict regimen was actually improving their sex life. It was, as she often pointed out to him, one of the reasons why the Female Led Relationship was better for both parties.
It was no coincidence that David and Mary's careers both found a lot of new clients and investors taking an interest in their work. The women in Ann's circle might not be actively involved in the day to day of the businesses they invested in, but their voice still carried a lot of weight. They were a powerful behind the scenes force and it was clear that belonging to their circle made a lot of difference in David and Mary's standard of living. Of course it came at a price; Ann as well as the rest of the women seemed to be much more involved in David and Mary's life, and on some intimate details.
Many of the women had no one to mentor in the lifestyle. Consequently, as the youngest member of the group, Mary was frequently the object of unasked for advice from the older women. Mary was gracious about it, and actually found some of it to be quite helpful in her training of David. Ann's stature as Mary's sponsoring member was also increased, which naturally made the relationship between Mary and her mother much closer, which also had its pros and cons. Most of all, as the only member with a living spouse or submissive there was almost continual talk of having her arrange more entertainment with David as the star attraction.
Mary had taken that idea to heart and thought that her stamina training might be just the thing to show off to the group. Things had progressed rapidly since her admission to the group and she no longer found it necessary to get David's sign off on her plans, though she sometimes still went through the motions to make him feel better about what was going to happen anyway. For his part, whenever David started to have reservations or doubts about the arrangement he had only to be reminded that he was getting more sexual activity than he ever thought possible, not to mention the variety.
It was like this when Mary brought up the idea of showing him off to the women of the group. When he had been orally servicing the women of the group he got the idea that many of them would have liked it if he could have penetrated them with more than his tongue. So David was amenable to the idea from the beginning. Even though Mary would technically be the hostess for the event it made more sense for the location to be at Ann's. Even though Ann was uninterested in seeing erect penises, or having any sexual contact with them, many of the other ladies did, and Ann would not object as it was Mary's party.
Mary and David greeted the guests as they arrived and David served cocktails and hors d'oeuvres in the living room. For all appearances it could have been any ordinary party of friends. Only the smiles and anticipatory twinkles in the eyes of the guests hinted that there was more in store than good conversation, food and drink. After everyone had arrived and had a little time to snack and drink Ann stood up to make an announcement.
"As you know, our newest member, my daughter Mary, has asked to provide us some entertainment this evening. She has been working very hard training her husband and would like to show him off to us, and for us. Well, those who are interested in sampling him," she smiled. Gesturing to Mary, Ann yielded the floor.
"I've been working on David's stamina, and I believe we are at a point where he needs to be challenged on his endurance. So tonight I will be the first to put him to the test, and then as many of you as would like, may enjoy his penis. The rules of the event are as follows:
1. All sexual contact has to exclusively include penile stimulation,
2. He is not allowed to orgasm,
3. If he does he gets 24 cane strokes and must clean up the cream pie,
4. If he attempts to hide his orgasm he gets 36 strokes instead of 24,
5. Any woman he cums in may administer the cane strokes if she desires,
6. In the event of his orgasm as soon as erection can be restored he must again resume servicing the women; unless the Mistress of Ceremonies, me, determines that he will not be able to continue.
"That's about it, shall we go to the 'play room'?"
The crowd began to move to Ann's basement with eager anticipation. For the event a small day bed had been set up next to the spanking sawhorse. The chairs were still there, arranged around the bed and sawhorse. Apparently all of the intercourse was to be witnessed.
"Those who wish to actively participate should disrobe and take one of the chairs closest to the bed," Mary announced as she and David were stripping.
Mary had given David every chance to make a good showing. She had given him a high dose of Viagra and a quickie ruined orgasm before they arrived so he could control his arousal easier. It really was something for both of them to be proud of, and he wanted to make a success of it as much as Mary did. They both knew that he would ultimately fail to hold off his orgasm before finishing all of the women, but he still agreed because he wanted to see how far he could go. The idea of performing in front of others might have seemed off putting at first, but it soon became clear to him that every one of the women in the group had seen him beaten and humiliated before, and he had orally serviced most, if not all, of them, so there really wasn't any reason to be modest or embarrassed.
Mary lay back on the bed and spread her legs invitingly. David was already hard and he could see that she was already wet and ready. He entered her and quickly slid all the way into her warm, wet pussy. As they had previously discussed, their technique was more "business like" and less like their actual love making. David's thrusts were regular and steady, full length penetrations. Since they both wanted the demonstration to be a success they were faced with a bit of dilemma; the less time he was in Mary the longer he would be able to last with the others, but he needed to be in Mary long enough to surpass usual limits for anyone to be impressed with the stamina training. Once he passed the five minute mark he was doing better than 50% of the male population. Mary was having to hold herself off from cumming as well, they had discussed this and wanted the focus to be on how long the intercourse was lasting. At seven minutes Mary let herself go, and with loud moans and shaking she reached her orgasm while David continued to steadily plow her love tunnel. Mary experienced several more shudders and "after shocks" while David was clearly still erect and penetrating her fully. At ten minutes she indicated he should pull out. He was still erect and clearly had not cum. At this point his performance was already better than 75% of men. The women applauded.
Not to take anything away from David's already stunning performance, but he and Mary had already completed what they thought would be the most difficult part - the initial length of time and lasting through her orgasm. Mary assumed that the older women wouldn't be able to stand penetration for long before the thin and delicate skin of their sex would feel raw, so David shouldn't have to last too long with any of them. Then the break between partners should give him a chance to cool down a little.
There might have been a rush for the bed but for some sort of predetermined order everyone abided by. The first taker was a plain and stern looking lady in her late 40's with a tall, thin face. She had on a light green coat, which she threw open to reveal that under it she was only wearing black net stockings and a halter top of the same material. Her bush was sparse, except right around her inner labia, which were thick and long. David would have loved to suck on those lips, and tickle her clit with his tongue but tonight was not about those pleasures.
He doused his member with some lubricant and entered her. She was tight, as he expected but it soon became clear to him that something else was happening. She was clenching her pussy muscles. She was trying to make him cum. She wanted to see him caned!
"Come on," she encouraged in what was supposed to be a seductive tone. "Cum in me!"
Despite her words there was an undertone of vicious meanness. That only made David resolve to fight harder. This was no longer just about sex and stamina.
He adjusted his position to ride a little higher, letting those long labia catch on his cock and pull on her clit with each thrust. Soon he could feel that she was wetter. He kept up his efforts now that he could see his plan had a chance of succeeding.
She had her eyes and mouth closed tight, it was clear she was trying to resist the stimulation that was propelling her toward orgasm. David knew his plan was working, if only he could hold out longer despite the tight grip on his penis. Suddenly he had the idea that he should turn her verbal tactic against her.
"Your lovely pussy is so tight. Do I fill it nicely for you?" he asked in a soft and complimentary tone.
