Brigitte let alone for a moment her niece Virginia who had fainted during a momentous fist fucking. She had pulled off her hand from her submissive's arse and had replaced it by the neck of a Champagne bottle she had pushed in up to the middle of the bottle.
- Now, my dear Marie Laure, perhaps we could focus on your problem, don't you think so? Stand up and on the double!
Brigitte had taken from a cupboard the long whip she had used some time earlier to punish Virginia. Marie Laure had just practiced partner swapping with her cousin Brigitte. Jean was a very good lover, very demanding, as Marie Laure could have attested! She had never even disrobed in front of her cousin and never submitted to her. She turned toward Marc who was watching her with a big approving smile. Ostensibly, she couldn't expect any help from him. It was even possible that Brigitte, Jean and he had conspired together. Marc had nurtured her inner drives toward exhibition and submission but up to now, only strangers had been allowed to benefit from it. Her mother and sister shared these drives and both of them were now fully dominated by Marc.
It seemed that, now, Marc wanted to offer her to Brigitte and John. They were cousins although they didn't belong to their family inner circle. Moreover, they were clearly experienced dominators. She shivered when she realized they lived a short distance from her home. Brigitte was a housewife : she and John could easily come and visit her, inflicting as many humiliations, ordeals and punishments as they cared whenever they decided so. It was definitely Marc's idea as he told her :
- Darling, I would like Brigitte and Jean to have the keys of our apartment. Could you give them your own keys!
Marie Laure suddenly felt she was in the center of a terrible nightmare as she opened her bag, fumbled into it to find her keys. The key ring was a gift from Marc with her surname in silver plated metal. She wished to keep this small gift from Marc but he stopped her gesture when she tried to free the ring.
- Let it stay with your name on it! Thus, Brigitte will be immediately able to find your keys. I've prepared another set of keys for you.
He immediately handed her another pack of keys. There was also a key holder with a tag with attached letters forming a word. These ones were black. Marie Laure turned it around to be able to read what word was formed in capital letters. She read aloud : Slut!
- It will be funny to inform you that way of the role you'll be asked to play in the coming weeks . I've ready a whole series of them. I want you to promise here and now you will abide to the role that will be specified on your keys, whatever I ask you to do!
Marie Laure felt as if a wide and deep abyss was gaping open in front of her. Marc was asking, no demanding her to take options on her future, to promise to obey him totally like a slave. Her implied future was scaring her but was also terribly exciting. How far was he intending to lead her? She hadn't the least idea of it and it gave the situation all its gusto. She answered in a whisper:
- Yes, Marc. Ahem, . . . no, your slut should have said: yes, Master!
- Good! As you've just admitted your true nature, why do you delay abiding to Brigitte's orders? From now on, you must obey to her as completely as you do with me and it'll be the same thing with Jean. I think she is anxious to see you naked! I can see she has some decisive argument in her hand to force you to comply.
Brigitte was playing quietly with her long whip. Marie Laure couldn't expect any help either from Marc of from Jean who both seemed quite excited by these new developments, Marie Laure had no options but to obey. She slowly unbuttoned her top and carefully arranged it on a chair, She unzipped her skirt and unhooked it at her waist. She was blushing beet root. Her skirt unfolded itself and fell to the floor. It ended above her top on the chair. Marie Laure had driven her car without any bra or knickers. Her ensuing nudity explained the pink color that suffused her cheeks.
Brigitte walked slowly to the sundeck and sat on an armchair, ordering the young woman to follow her. As Marie Laure wasn't obeying fast enough to her taste, She turned toward her and administered a sharp stroke with her still coiled whip on the back of Marie Laure's ass cheeks. She jumped forward and, without any protest, she followed meekly Brigitte. She made her stand at attention in front of the armchair she had chosen. She went inside to fetch several implements, leaving Marie Laure in the full heat of the sun with stern instructions not to move a toe. The natural authority that oozed from the older woman was sufficient to keep Marie Laure from disobedience and protest. She was tamed and realized it.
Brigitte came back with a golden string she weaved carefully around Marie Laure's chest into a tight corset : one loop under her breasts, one above and every five ones, a loop around each tit. The global result was breathtaking : the breasts were perfectly supported, jutting proudly forward and perfectly separated. Marie Laure's breath was now significantly reduced to her belly that heaved frenetically. When Brigitte completed her weaving, Marie Laure's nipples only weren't covered. She completed her handiwork with a big bow just between Marie Laure's breasts.
