Try to appear defiant.

I was well aware that putting up any resistance to Captain Domino was futile. Though we were perfectly matched in size and strength she possessed well honed unarmed combat skills and had all the tools at her disposal to render me helpless if she decided it was necessary. Besides that, my plan was to gain a measure of trust with the Helcions and free the other prisoners to somehow take over the entire ship. With the oversexed Helcions that meant proving I was he best fuck they they could have as much as making myself indispensable by repairing and maintaining the ship's systems.

Captain Domino's sexual desires, from the little interaction I had with her so far, were aggressively dominant and driven by a superiority complex and massively overinflated ego. I probably had a big advantage having been rebuilt by the nanobots as her duplicate, I presented a challange and wore the body and face she thought was perfection. I gave a toss of my head, making the long afro curls bounce and gave her a look I hoped was sexy and defiant enough to fixate the Captain on conquering me and winning my devotion.

"You think a little fucking will break the spirit of a United Colonies spacer?" I challenged. "You Helcions underestimate us."

Domino grinned at my show of defiance, clearly relishing the opportunity to prove me wrong. She licked her lips hungrily as she stared down at my naked body, her narcissism plainly loving the sight of her own body stripped naked and under her control. With a throaty growl, the Captain pounced, grabbing a fistful of my black curls and flipped me over to lay face down on her bed. I made a show of spitting defiance and curses as my arms were **** behind my back and the magcuffs on my wrists were locked together, then each of my legs were folded back and the cuffs on my ankles locked to my wrists.

"That should keep you put Sweetcheeks." Domino observed, "You have a nice squirm there until I'm ready to give you a fucking you'll never forget."

Hogcuffed by the magnetic restraints, squirming on the bed was all the movement I could manage. I made a big show of growling and swearing as I fought against the obviously inescapable shackles. I wriggled my body around looked back over my shoulder and observed Domino through the stray strands of tight black curls fallen over my face. The Helcion went to a plexiglass door and it slid open to reveal a shower similar to the one in the medbay.

The Captain stripped off her belt and harness holding her weapons and other gear and then her boots before entering the shower cubicle clad only in her black ruanite catsuit. The shower activated and after a couple of seconds, it became clear that the jets sprayed more than simple water. The shiny black ruanite bodysuit melted away and sloughed from the Captain's body leaving her Amazonian body nude and glistening. I did not have to feign appreciation and aroused interest in Domino's naked body. Her large breasts were firm and proudly perky with long rigid nipples, her hips wide to accentuate the muscular hourglass figure. The Captain ran her hands over her nude body, understandably conceited by the strength and desirability of her physique.

"Oh fuck!" I swore, staring as Domino stepped out of the cubicle with her body still glistening wetly.

Domino strode across the room to the racked weapons and devices, her firm rounded breasts and buttocks jiggling with each step. She searched for a moment and then picked a black case and came over to the bed and placed it near my face so I could see the contents as she opened it. Inside the case was a cybercock. We had similar devices in UCS space, double-ended phallic toys that could have various electronic enhancements. The standard model simply had neuron interface meaning the sensations of tightness, dampness and friction were transmitted from one half of the dildo wearer's vaginal nerves, in other words, the fake cock felt like having a real penis for the wearer. Other enhancements could include vibration or electrostimulation or even the ability to ejaculate liquids either on command or when a threshold of stimulation was reached.

Some cybercocks were modelled to look lifelike, flexible and coated with plastiskin. Domino's oversized fake cock was sparkling silver with pronounced ridges and flashing blue strobe lights running in lines down its considerable length. I did not doubt that the Captain's cybercock would be a top-of-the-range model with every effect imaginable built into it. Helcion technology was on a par with the United Colonies, perhaps a little in advance, that state-of-the-art toy was likely worth several years of my pay as a space fleet engineer.

"Oh shit that is huge." I gasped honestly, intimidated by the size and girth of the displayed cybercock.

The two halves were in truth mismatched in size, as Domino lifted the cybercock and spread her legs to insert one end into herself it was no surprise the smaller end of the cybercock would be inserted into her own pussy. That end was still longer and thicker than my now vanished dick, but the end she intended to fuck me with was thicker than my wrist and as long as my forearm. The Captain chuckled at my undisguised awe and trepidation at the prospect of being fucked by such an oversized toy. Rubbing the tip of the more modest end up and down her labia she slowly slid the cybercock into herself. The Captain's slit was as smoothly hairless as every Helcion's and ****'s I had seen on the ship. Pubic hair seemed to be either aesthetically unpleasing to Helcions or their penchant for skintight ruanite made hairy bushes impractical.

"Not so cocky now Sweetcheeks?" Domino smirked, stroking the thick cock that now sprouted from her loins and sighing happily as she felt her fingers running up and down its shaft. "But don't worry you'll soon be feeling all the cock you could want."
