It would be the most terrifying thing she had ever done, and I was incredibly proud of her for having agreed to try this. That spoke great volumes for her trust in Me.
What years ago had begun as something to pass the time between systems had evolved into a full-time official Master/slave relationship. Already, there was a hierarchy - I was the Captain and she was the subordinate on the small cargo craft, and only rarely would there be anyone else aboard - so perhaps the Master/slave relationship was a natural progression.
Across the years, I had become more devious in My plans for her. My heart had turned dark - still filled with love for her, but also desiring more and more to see her suffering for Me. That suffering could be physical or psychological - or, ideally, both - but something in Me simply longed to witness her suffering by almost any means possible.
Asphyxia was indeed a part of that. I cannot say that she truly thoroughly enjoys it, but she definitely tolerates it because she knows that I enjoy making her suffer, whatever form that suffering may take. When I choke her or strangle her, the wide-open eyes provide a great window into her distressed mind, and I can almost peer into her anguishing lungs. The raspy sounds passing between her parted lips provide an aural verification of her plight, and if I kiss her during such moments, I can feel the scant nature of her shallow breaths. As her face reddens, it makes her consensual torment all the more enjoyable for Me.
But I must admit that when the idea came to Me, I hesitated for a long, long time before I finally broached the subject with her, for I honestly did not expect that she would agree. Perhaps she knew that this would happen eventually, that My twisted mind would concoct this specific scenario.
"It's time," I said flatly, and she knew exactly what I meant. With a solemn nod, she rose from the chair and began to undress, removing everything save for the thin fused ring of titanium encircling her dainty neck, for this time, there would be no compression of her throat.
I lingered for a moment, watching as she began to bare her body once again, before I left her to gather the required supplies. A few minutes later, I approached the airlock and she was already there, already inside, kneeling, her head downcast and her wrists crossed behind her per her extensive training. I saw her in profile, which further emphasized her deep breaths as she tried to calm and steady herself for this experience.
Leaving everything except the old-fashioned rope outside the airlock, I approached her. This was quite familiar to her, and very much welcome, for she yearned to be restrained in any manner My strange mind could concoct. I took My time, allowing her to revel in the purposely-slow process of securing her ankles together, restraining her legs together, lashing her forearms together behind her, binding her upper arms to the sides of her torso while placing the ropes strategically to visually emphasize her chest and heighten the sensitivity of her breasts.
Kneeling behind her, I fondled My slave and partner and colleague and best friend. My lips kept pressing against her cheeks. My fingers kept pinching her nipples. My fingernails kept grazing the base of her breasts.
My teeth kept nibbling on either side of her vulnerable neck.
When she was equally aroused and nervous, I gave her a final kiss to the top of her hairless scalp and rose to My knees. It was time.
Exiting the airlock, I took My time in changing clothes and donning the breather mask. When she saw Me again, I was clad entirely in black, the form-fitting outfit one she had not seen previously. I know that she had never seen the breather, for she visibly cringed at seeing the massive black mask with the bulbous black eyeshields and the trio of large breathing ports with the multiple layers of black filters. she likely noticed the black straps around My shoulders and My upper chest, but she could not see the small oxygen tank they supported at My upper back.
I kept My steps slow and loud, purposely adding to her nervousness and her growing fear. Within the massive mask, I sneered, My ego quite proud of her attempts to shy away despite her tight bondage. Only if she was the best contortionist in the universe could she possibly have had even a glimmer of a chance at freeing herself under normal circumstances, but with the dread and the fear seizing her throat and already clearly making it difficult for her to breathe, she would only gain her freedom when I released her at last.
Entering a combination in the keypad on the inside of the airlock caused the inner door to close and seal, the sound almost having a quality of finality. The outer door was still closed and sealed, as it had been for nearly a full week since the departure from Kuptera Station. The pair of small windows provided a nice view of the stars unknown light-years distant as they speckled the ever-present blackness of deep space.
