After his gesture of acceptance of Mary's complete control of his sexuality she asked him for his ideas for a formal ceremony or ritual they could perform to make it "more official". David could only think of a written certificate that acknowledged her control. He envisioned it printed in script on fancy paper with detailed lines and webbing, like on money, and perhaps even a seal with a ribbon. Mary liked the idea and he went to work on the language.
As he brought the finished product to her she was thrilled until he started to sign it.
"Wait! You aren't just going to sign it like that are you?"
"Well, what else is there to do?" he asked truly confused.
"For starters shouldn't it be witnessed?"
"Oh, yeah, I suppose so, but..." Before he could wonder aloud who would be the witness Mary broke in with "Mother would be happy to do it for us. In fact she would be thrilled. Maybe even disappointed if we didn't include her," David had an uncomfortable feeling about it all, but he couldn't quite say why.
"Did you think of any ritual to go along with the signing?" Mary asked innocently.
"Well you could get me close to cumming, deny me and then lock me up while I get you off," he offered tentatively.
"Perhaps something like that," she responded, reflectively. Then after a moment she continued.
"David, dear, there's something I need to tell you. There was more to your trip to Mother's to 'entertain' her women's group. You see I have known about her group for a while and I wanted to join. They're a very private and exclusive group of powerful women. Mostly they act behind the scenes, but I think they could be helpful to me on many levels, both professionally and personally. As you can see, they haven't admitted anyone in quite some time, especially someone my age. Mother's request was in answer to mine to join them. Having you make a good showing with them was a way for me to get them to admit me. But I was telling the truth, it was up to you to agree to go. I didn't tell you the rest because I didn't want to pressure you with my membership pending. And it worked! It was your choice, and you got me in!"
It was a lot for David to take in, so he just stared trying to put all the pieces together.
"Are you mad? Are we OK?" Mary asked with genuine concern in her voice.
"No, not mad. We're fine. It's just a surprise to me. And I'm confused about why you bring it up now?"
"Because I'm thinking that in front of Mom's group would be the perfect place for this ceremony of ours."
David was immediately suspicious, but again couldn't say why. "There's more to it, isn't there?" he asked tentatively.
Mary smiled, "Well yes, there is, my smart boy. You already know that these are sexually dominant women. It was and is important for them to see that I am in control of you. Your performance the other weekend was good, and it showed how much you would submit to, including the chastity cage, at my request. It seems only fitting that they be the witnesses for making it 'official'."
David agreed, although deep down he knew that he really didn't have a choice and his agreement was more of a gesture.
"Good, then I'll set it up with Mom," she said cheerily.
"And the ritual?" he asked.
"I think the night you agreed to submit to my authority has the right elements. I'll work out the details, don't you worry about it."
The time till the ceremony passed slowly for David. He kept going over the details of that fateful night when he agreed to submit to Mary. Would she really make him drink her piss in front of the whole group? At least when he did it with some of those same ladies it was one on one, in private. He got very nervous about the upcoming ceremony and would try to calm himself by remembering that he got through it once, he could do it again. And besides, Mary loved him, she wouldn't make it any worse than it had to be.
When they arrived at Ann's they both entered through the side door, but Miss Ann directed David to her room while Mary waited behind to be announced into the living room. In Miss Ann's room David disrobed and fitted his chastity cage, but left off the lock. There was nothing more to do but wait for Miss Ann to return and escort him to the main room. During what seemed like a long wait he got nervous again, and tried to calm himself by re-reading and rehearsing his pledge which had been worked into a fine certificate with printed webbing and calligraphy with a ribbon seal. At last Miss Ann came for him and escorted him to the living room, where Mary was standing in the middle with all of the women in the group standing and sitting around the room.
"Go kneel in front of her, and read your certificate, then give it to her with the lock," Miss Ann whispered in his ear.
David walked to Mary, looking only at her, and trying to ignore the audience. Kneeling he said, "I, David, do hereby grant, bestow and transfer my right to sexual orgasm to Mary, my wife. I make this gift out of love. I pledge to provide Mary with orgasms whenever, and however, she desires with no expectation of reciprocation of any kind. Henceforth, I will not, nor will I allow anyone else, to cause me to orgasm without Mary's permission. The frequency and manner of my orgasms will be entirely at Mary's discretion. She is hereby also granted the prerogative to determine appropriate consequences for unauthorized orgasms, and to determine if I should be required to wear a device to prevent unauthorized orgasms. This gift shall remain in force during the entire life of our relationship." With those final words he signed the certificate and handed the lock to her. Miss Ann signed as witness and gave Mary the paper.
"Thank you, dear. You may stand." When he did she fastened the lock to his chastity device and with a hand gesture indicated that he should kneel again. The audience of witnesses applauded. It was all going so well. Mary was wearing a wraparound skirt, which she now undid and let fall to the floor, with the words, "You may now please me orally."
She had no underwear on, but she was wearing a sanitary napkin. Mary never wore those, preferring tampons. Then he realized that it was to demonstrate her condition and ease its removal. Mary was always horny when she got her period. Even though they had never had sex during that time, David knew she masturbated through it, as he once did. Her flow was always heaviest the first day or two of her period, when the pad was removed it was clear that's where she was in her cycle. David looked up at her with silent pleading in his eyes. She just repeated the words of his pledge, "...whenever, and however, she desires..." with an odd smile.
Trying not to show too much hesitation, he bent to his task. The smell was overwhelming, he tried to stifle a gag response, he thought successfully. He pushed past that to put his tongue in her bloody pussy folds. The taste was metallic, and the sensation was very sticky. Eventually he was lying on the floor while she sat on his face. This position accentuated her flow and at times he could actually feel a little rivulet of blood running into his mouth. He could hear approving sounds from Mary and the audience as his efforts did seem to please her. After what seemed like an eternity he heard the familiar sounds of Mary's orgasm. During her peak, juices that were both her arousal and her menstrual blood bathed his face.
