The culmination of the annual celebration of the glory of the Nakozi interstellar empire was a formal reception attended by a multitude of high-level officials, rich businesspeople, aristocrats, and foreign dignitaries, including diplomats from client races. Kaboshi was enjoying himself very much as he wandered casually through the halls, delighting in the colorful sights around him, and stopping every now and then to exchange greetings and embraces with many friends and acquaintances on this joyous occasion--Domestication Day! Nakozi loved ceremonies and ritual celebrations, and this was the supreme event of the year, celebrating the glorious fertility and lactation that humans had achieved under benevolent Nakozi rule.
Kaboshi paused to adjust his tie, who was squirming again. Like every other Nakozi at the reception, Kaboshi's towering, elongated frame was adorned as he walked along by a very decorative naked human female (a hugely pregnant human female) who was solidly mounted on his cock. She was facing out from his torso, with her arms raised above her head so that her bound wrists met behind his neck, while her legs were bent backwards, with her ankles likewise bound behind his lower back, so that her entire weight rested on the cock she was riding. A short chain linked her wrist and ankle bindings and kept her from slipping.
Wearing ties to work and to formal occasions was one of the very few Nakozi borrowings from human culture, although the Nakozi had definitely put their own spin on it. Fortunately, human females came in a wonderful variety of races, colors, shapes, and sizes (though continued selective breeding had led to a general top-heaviness), so one could find a tie to suit every taste; and particularly flashy or artistic individuals could even body-paint theirs for added color. Kaboshi personally favored redheads, and the tie he usually wore to the office had flaming red hair, top and bottom; he enjoyed stroking her abundant bush during particularly boring meetings.
(Kaboshi's preference for pale-skinned redheads dated back to his school days. Like every other young Nakozi, he had attended mandatory classes on human anatomy and the care and feeding of female humans in particular. His teacher, Mr. Horomi, wore a long-limbed redhead to work, who doubled as a demonstration model and practice dummy, not to mention a drinking fountain for the children during recess. The female was remarkably docile and very patient with being poked and prodded in every orifice by immature Nakozi; Kaboshi remembered her fondly, and sometimes wondered whether she had been an elementary school teacher herself before domestication. One of Kaboshi's proudest memories was of the time when he had won a competition organized by Mr. Horomi as part of their final exam to see who could bring the redhead to orgasm fastest. Although he was not yet old enough to have an erection himself, he had discovered for himself that fisting a human female worked very well. The sensitive and responsive red tie, who had fainted after a thunderous orgasm, had thanked him with tears in her eyes, in her adorable pidgin Nakozi that sounded so much like baby talk.)
Like every other human female at the reception being worn by a Nakozi, the lovely animal Kaboshi was now wearing would periodically use whatever leverage she could get from her wrists and ankles to slide herself up his torso slightly, in a vain effort to keep her cervix above the tip of his massive cock. The female human necktie did not have the strength to hold herself up by her arms for long, though, and would find herself sliding back down his shaft again, gasping as she was once again completely impaled--hence the squirming.
Kaboshi found this little game, which did exquisite things to his throbbing cock, absolutely delightful, and judging by the fragrance of sweat and sexual arousal, his tie seemed to be enjoying herself, too. He wondered how long it would be before she would shudder against him in orgasm, even if he refrained from playing with her, as he absolutely intended to do. Kaboshi, of course, as a Nakozi, could maintain his erection for many hours, and would not ejaculate until he saw fit. This was one more proof of the obvious superiority of Nakozi to lesser species.
In the meantime, he was enjoying her soft, warm weight (which, though substantial, was as nothing to a powerfully built Nakozi), the heat of her firm buttocks nestled against his belly, her musky scent, her charming little gasps and moans, the way that her heavy milk-laden breasts swayed from side to side as he bore her along, her very pregnant belly protruding before them as Kaboshi walked along, and most of all, the way that her sweet, tight cunt grasped his member so firmly. Even the way that the light in the hall shimmered off her oiled and sweaty skin, as well as off the bodies of the thousands of other human women on public display at the reception, added to his enjoyment of the occasion.
The droplets of milk already leaking from so many swollen black nipples at the tips of so many bobbing and swinging massive blue-black, dark brown, and chocolate breasts were also arousing as Kaboshi passed by other guests in the crowd. The pregnancy-swollen breasts resting on top of protuberant, ready-to-burst bellies proceeded their wearers like the busty naked figureheads of a fleet of ancient human sailing vessels, bobbing up and down as they were borne across the waves.
Kaboshi's tie was a rental, of course, and probably so were most of the other human women here. Few Nakozi would just happen to have one at home that would meet the proper specifications, at least in time for this reception. (Similarly, in ages past, human men would often rent a tuxedo rather than buy one for a special event.) Kaboshi had rented her online from an AI agency that specialized in providing human females certified to be of the proper race for formal occasions, appropriate stage of pregnancy (8.5 months), and attractiveness for a social occasion of this magnitude, and of course in perfect health and housebroken. Within hours, a drone had appeared at his home dangling this voluptuous black-nippled female hogtied below it. The broker had guaranteed that she would already be bound hand and foot and ready to mount, oiled from head to toe, prelubricated, and temporarily devoiced (of course you don't want your own tie interrupting a conversation with unwanted vocalizations).
The drone's AI further assured him aloud upon its arrival that she had been given enough food and water to last her through the evening, though he was of course welcome to give her as many treats as he desired. Her bladder and bowels had already been evacuated, as a precaution to prevent any messy accidents, just in case. It also mentioned discreetly that she had a tracking chip installed to forestall theft, though of course this esteemed customer would never consider such a thing. Finally, it gave him an estimate of her hourly milk production, and reminded him that the rental fee included the consumption of whatever milk she could produce for him during her rental period.
All Kaboshi had to do was enter the unique electronic code he had been given to release her from the drone's restraints, then after the drone had carefully deposited her on the floor, use the wrist and ankle restraints to slip the famale onto his body, and then slip his cock inside her; and then he was ready to leave for the reception. The chocolate-brown beauty who had groaned and smiled when he entered her was already writhing langorously and seductively; she was clearly aware that she was high-quality merchandise.
When he was done with her at the end of the evening, all he would need to do was feed her back into the drone's restraint system, which would use its articulated arms to seize and package her as soon as her tracking chip came back within range, and the by then well-used and exhausted fleshy cargo would be sailing silently off into the sky on her way back where she belonged for inspection, cleaning, and return to her breeding pen. The automated rental and return process really could not have been any easier; but then of course the agency had been in this business for a long, long time.
If Kaboshi were pleased enough with this one, he might make a note of her inventory control number (human females were not given names, of course, at least not on any civilized planet), and reserve her for the following year. After she gave birth, her AI owners, as per best livestock management practices, would allow her a couple of months to recover before impregnating her again. Her belly should ripen in time to rent her out for the following Domestication Day celebations. And so the cycle would continue for her, for the rest of her life, or at least while the female remained fertile.
Kaboshi continued walking through the hallways of the Domestication Day celebration, occasionally feeding his tie a treat or a cube of cheese (human cheese, of course--there were no other milk-producing mammals on this planet). Her full, sensitive lips would delicately take it from his fingers, and she would gratefully swallow.
He ran into a close friend in front of the display presenting the holiday's history, and they embraced, pressing their ties' chests against each other, while being reasonably careful not to put too much pressure on the females' bulging bellies. Kaboshi and his friend exchanged polite compliments on the beauty and fertility of their ties, while the latter stared smiling into each other's big brown eyes. Kaboshi wondered briefly whether they knew each other; for all he could tell, they could have been sisters, or one could have birthed the other.
After his friend carried his own jiggling and sighing human female away, while casually raising her left breast to his mouth for a sip of milk as he walked, Kaboshi remained at the display, browsing the slideshow about the history of Nakozi-Terran relations, while casually playing with his tie's breasts, jiggling them in his hands or twiddling her nipples. He knew all about that history, of course, as a scholar specializing in the subject, but the story will amused him.
