**Experimental Hybrid Breeding

F-22E-R053's sensors came online as a presence was detected within the maintenance bay/laboratory where she lived, and she cut the entertainment feed she was watching while running a few background updates. It was Doctor Karl, her creator and father-in-spirit, accompanied by another uniformed airman.

"Good morning, Rose!" the draconic scientist greeted cheerily. "Any hiccups in the updates? Anything to report?"

"No, doctor," she answered, double checking her diagnostics. "I am running at optimal efficiency and updates are almost complete. I have found some irregularities in the update contents, however."

"Oh, nothing irregular at all, Rosie, my girl! The last one is a bit of a patch I put together for the bigwigs. It's a test, an experiment. We're going to try something you were deeeeefinitely not designed for per original specs, but it's an idea that caught the attention of the brass and they gave it the go-ahead."

This intrigued and excited her. She was always happy to push the limits of her specifications and was very pleased to please her creator by exceeding expectations. "What kind of experiment, doctor?"

"Lieutenant Atchison here will be assisting us. If you will, lieutenant?"

The large canine, a St. Bernard, hefted up the case it had been carrying and let it thunk onto a clear workbench, then flipped up the clasps and cracked it open. Inside was an attachment specified in the update which corresponded to the visual and video images that were also included. Fifteen inches long, at least four and a half around, and with a hefty set of nanite processors beneath, it resembled a much enlarged erect canine phallus.

"I assisted in the design myself," the lieutenant advised with a wide grin. "I like 'em big."

"So, for the record, the experiment is to determine if your repair nanites can be repurposed to act as sperm for purposes of insemination. They have theoretically limitless capabilities, but they haven't been tested in this particular manner before. Even with the advances in cybernetics, creating a 'super soldier' is still an expensive and highly invasive process. If, on the other hand, we can grow them from scratch with enhancements already built in... well, bingo! That's some bang for your buck, eh Rose?"

She processed it for a moment before responding. "That was a double entendre, correct?"

"Haha, I told you she's quick on the uptake!" he said in aside to the canine before continuing. "Alright, Rose, go ahead and get your attachment installed while Lt. Atchison gets ready."

The aeromorph replied in the affirmative and retrieved the unusual device, seating it in the female port between her legs. It was situated such for easy reach by the doctor and any technicians, considering her fifteen foot height, allowing them to insert charging cables and diagnostic tools. The new attachment felt... odd but also correct, for while she was technically androgenous, she did think of herself in a feminine way. The updates had somewhat shifted that perspective, making this new piece of equipment a part of her personality as well as physicality, creating a harmony with her previous programming.

After ensuring that the device was properly seated, she looked up to find the St. Bernard nude and bent over the workbench, looking back at her with an eager pant and a wagging tail. From the update, she could see that the canine was in heat from the inflamed vulva, though the erect phallus bobbing beneath was also an indication of heavy arousal.

"Integration is complete, doctor," Rose advised, feeding power into the mechanism. It rose to stand out perpendicular to her frame, easily twice the size of Atchison's. "Shall we proceed with the experiment?"

"Get over here and stop making me wait!" the canine herm barked, with the dragon adding, "You heard her!"

The aeromorph complied, lowering herself to her knees behind the much smaller lieutenant and placed a hand around the breeding apparatus to carefully line it up with the slick slit of her excited partner in science. Her database suggested that further lubrication should be applied to prevent harmful interaction, and she drew on her internal reservoir to pump it through the shaft in her hand, feeling an odd sensation from its sensors as the rush of fluid ran through it to splatter against the canine.

Then she pressed forward, seating the pointed tip of the phallus at the vaginal entrance and pressing inward. Now, too, were new sensations. Not new in and of themselves; her body had temperature and pressure sensors built in, but these inputs were much greater than the norm, probably designed to assist in preventing harmful interaction. As she pushed inward, she could intimately feel the glide of slick flesh against her polymer-steel attachment, each flex of muscle and each ripple of the surface inside the canine. It was an interesting phenomenon.

She could have simply seated the apparatus inside the lieutenant and proceeded with expelling the repurposed nanites, but content from the update indicated that there was a process to this kind of thing. So Rose instead took hold of the St. Bernard's hips and plunged in to the bulge at the base of the synthetic phallus, a slow insertion that tested the herm's depths, and found that the full length could be inserted without causing damage. The happy whine and increasing frequency of the wagging tail were also indicators of acceptable parameters. With this data logged, the aeromorph drew back until just the tip remained with those warm, moist walls and drove inwards once more.

The motions were mechanical at first, a simple in and out piston-like motion, but the update was helpful in guiding her towards a more equitable interaction. She leaned forward over the lieutenant to give her hips a better range of motion, allowing her to press downwards on the in-stroke, grinding against what was labeled as the 'g-spot' within the feminine genitalia, and making sure to let the dangling processing units swing forward to stimulate the clitoris via impact pressure. She built from a slow grind to a more swift pace over the course of several minutes, running constant diagnostics and providing ample lubricant to ensure that no damage was incurred during the interaction.

There was also an interesting set of sensation data that was building up from the attachment. The warmth and pressure around it along with the friction of the motions were sending odd tingles through her circuits that had never been experienced before aside from a somewhat similar experience when going supersonic. The burst of pressure as she broke through the sound barrier and could boost her speed even further was preceded by a steady buildup that seemed related to the current data set, though it was caused by wholly different input.

She found herself relating more to the video content provided in the update and emulated it further, using her mandibles to clamp onto the panting, moaning, whining herm's thick scruff and give it a tug. Lt. Atchison responded by letting out a soft howl and bucking back against her, meeting her thrusts to increase the force of them. Rose adjusted her pace slightly to prevent accidental bruising and focused the angle of attack on stimulating the St. Bernard as much as possible.

When she felt the sudden crush and heard the loud howl of orgasm from the herm, she allowed the bulb at the base of the attachment to swell. It inflated within the vaginal canal, locking the pair of them together, but also triggering the release of the repurposed nanites. This was accompanied by the expected crash of sensation and elation that came with breaking the sound barrier, though in a much more contained locale, which seemed to intensify the sensation. That was no doubt assisted by the enhanced sensors that the breeding apparatus contained.

She continued thrusting for another minute, as indicated by the content update, then lifted a leg to carefully reposition herself facing away from the hermaphroditic canine, again as per the suggestions provided by her updated database.

"Hot damn," Atchison panted, still clenching around the attachment locked inside her. "I really hope it doesn't take so we can do this again!"

"I'm sure Rosie will be up for another round," the doctor chuckled. "Won't you, Rose?"

"Of course, doctor. I am always pleased to assist you in further experimentation."

The End
