The collar was a distraction. The endless stimulation, no matter the level, gradually wore away at the agent. Tasks took longer but that meant she spent longer amounts of time complying to her most recent orders. It was a never ending cycle. The robe may have hidden most of her signs of arousal but any one with keen senses of smell would no doubt catch her heated scent.

The shapeshifter collected her and brought her to the captain's quarters. The room was dark and the walls felt strange and sticky. The captain spoke directly into her mind. The collar still activated despite the non verbal commands. Robes were soon piled around Alexandra's feet before she stepped out of them.

She felt hands on her body, making her jump and try and see who was groping her. "Y-Yes, Master," she replied to his question. A soft coo escaped her as the collar rewarded her obedience. Juices trickled down her inner thighs. All this teasing and stimulation left the poor agent ripe for the picking.

Looking she didn't get too much detail. The captain appeared to be little more than a large dark shadow but she could feel his touch so he certainly wasn't a shadow. What she could see had been a lack of features other then dim yellow eyes that stood out in the darkness of the chamber.

That touch was slow against her rump, she was stuck there against the wall for the time being. The finger moved from her rear and traced against the collar she wore. An older model … its still effective ...

Her ass was then swatted with a slap, his touch cold but not overly so. The heat of her body was aware of the lack of heat from his. That single finger had not felt too much different as far as temperature went making her conclude that he could alter his temperature somewhat. After that slap he squeezed her ass as if for ripeness, his hand ceased playing with her hair to seize a tit in similar fashion.

If she had not been completely nude he tore away at her remaining clothing then. If she was then he saved himself a bit of time. Touching her, his hands swept down her arms and shoulders. A slight chill followed, his touch cold enough to harden her nipples and generate goose bumps.

He explored her with those hands then ran a finger up and down her spine. Yes, the finger wasn't as cold. When they ceased with her spine he spread her open, teasing two fingers against her labia and clit. Then two fingers pressed inside her, nice and slow at first, then picking up speed. He did not stop, not until she came.

His fingers were cold most of the time too. He altered the temperature a bit as he pierced her pulling them out after she came. Tonight you will be my test subject ...

She could hear him rummaging for something soon experiencing a shock as a taser-like device was applied to her shoulder sending a jolt of electricity through it.

The dark shadow started to molest her nude form. Alexandra shivered from the cold touch. Fingers closed around her heavy tit, the flesh molding around the shrouded digits. "Uhhnnn..." the agent groaned as she remained stuck to the wall. Her pulse throbbed with hot blood within the luscious globe.

Hands continued to roam over the Russian woman. Her body shivered as her breasts firmed and her nipples grew hard and erect. The chilling touch ran down her arms and stroked over her netherlips. The fingers wasted no time in spreading Alexandra open and finger fucking her into submission. Her groans and cries sound in the darkness until they crescendo into a soul numbing orgasm.

"Ohhhh..." Alexandra swayed weakly, her body tingling in a pleasant afterglow. The taser pressed to her shoulder, sending a current through her glistening body. "Auuuggghhh!" Her body shuddered violently as she remained stuck against the wall. She lasted only a few moments before her body slumped over, knocking the agent out completely. What cruel experiments did this captain have planned?

With her hands affixed to the wall she had not fallen, not completely. Rather she managed to land on her knees with her hands above her head at an angle stuck to the wall. The electricity of the taser had been full of warmth, contrary to the cold touch. She must not have been out for long as she could feel the throbbing of blood within her still erect nipples. Either that or it was colder. It was true that it was cooler but she was naked after all.

You have to last longer than that. There was a chuckle within her mind and while those words weren't vocalized the collar in sync with her brain interpreted them as orders. The longer she lasted the more pleasure the collar would feed her. The shadow captain had to have known this, perhaps that was what he was after.

Commanded to stand her legs would be shaky at first. Lengthy delays were meant with pain but as soon as she managed the pleasure began again.

A cold hand wrapped about a hip while the captain applied a device to her shoulders and back liberally. It massaged her skin in a circular fashion and had been akin to a rotating wand or brush. Where it touched it shot an infusion of heat through her for whatever reason. Something may have been applied to the bristles of the wand that transmitted something beneath her skin or it was a property of the device, it did not matter.

It stroked against her nice and slow, building on that warmth and soothing sensation, toying with the pleasure induced from the collar. At times that warmth felt searing for a second or two. No marks were left, the advantage of the wand, but every so often he toyed with her resistance to pain mixing it in with the pleasure.

Being tazed was not exactly something Alexandra had control over. But it did not matter what she thought. The collar responded and now every moment she was conscious would be filled with that intoxicating stimulation directly to the pleasure centers of her brain.

"Uhhnn..." she rose to her feet. Cold hands held her steady while some other devices were rubbed over her body. They were some sort of massaging devices. Heat filled her body. It ranged from gentle to searing. The heat rose to uncomfortable and even painful levels. But, there was no smell of burnt flesh or any signs of physical harm at all.

All during this, the collar kept feeding her mind that delicious pleasure. Heat filled the agent's cheeks as she moaned. Her body arched as juices began to drip down her inner thighs. She was not even trying to obey. She just happen to remain conscious and that was enough to deserve a reward. She did not understand the purpose of this experiment. Stuck to the wall, the agent could only groan as her toes curled against the hard floor.

The real experiment awaited her at their destination. This was just a bit of fun to kill the time until then that tickled his fancy. The collar, as simple as it was, fed her pleasure but would not hesitate if she couldn't endure by punishing her either interpreting the latest comment as orders, thus she was caught up in pleasure now.

But the variance of that heat made it easier to endure as any time she may have gotten to the point of loosing herself a bout of pain captured her attention. She was given a bit of a brake as the device was taken away. Areas that seemed to be on fire had been chilled by roving hands in effect soothing them. The touch was more of a relief now like putting ice on a burn.

Then he thrust into her, deep and sudden filling her. He was big. Not as big as some of the aliens she dealt with to this point but far from most. It was just a single thrust before spilling out of her. She received a small brake as the captain set aside the tool and brought over another.

Some sort of cylinder was pushed inside her, it twisted and turned vibrating with a soft hum as it pumped into her on it's own. One hand set on her hip, the other guiding himself to her back door where her own juice from earlier made a viable lubricant.

After poised at her rear and taking her other hip he pressed against her, slow at first in order to work himself inside her. Once inside her his thrusts were fairly quick and she felt him and the tool inside her at the same time.

Mm, nice and tight. She heard his approval as both he and the toy went to work on her. He seemed to be a shadow with substance or in the very least appeared to be a shadow of some sort. He took advantage of that toy and the collar working her ass all the while.

"Ahh... Ahh... Ahh..."

The agent was trapped. The sticky wall kept her upright while both machine and shadow thrust inside her tender depths. The collar ensured that every thrust, every vibration, felt better than the last.

The monster did not stop nor did the vibrator. Alexandra groaned as drool left her gaping mouth. Eyes fluttered and rolled back as she came then came again. She was being fucked through her orgasm only to be sent crashing down with another and another.

She lost track of time as she saw nothing in the darkness of the room. Her head started to nod off. Each thrust helped her stay conscious but exhaustion was winning the battle in the end. Her head slumped down only to jolt upright as the collar punished her mind directly. "Ohhh..." despite the stabbing agony, she came again as she was forced to stay awake.

The process continued as she was fucked into oblivion and brought back again and again. Alexandra's brain felt numb, unaware of the changes the collar was doing to her through this intense training.

He came hard into her ass, the cum felt cool. Good girl. He slid out of her smacking his dick on her ass and leaving some cum there. The machine was left as it was though piercing into her. Darkness hit. At first she had been confused then realized that the collar had not punished her so she had to still be conscious.

A sphere of darkness surrounded her head. The fucking continued soon afterwards. Scaly members from the feel of it and she knew then that the crew or at least some of them got to take turns. The sphere of darkness kept her identity hidden she guessed there had to be other humans here. With her facing the wall they noticed her breasts only when she was groped.

But she was beyond thinking too much about it. Her ass, lower back and ass cheeks had been drenched in cum. All the while the toy pressed into her despite how often she came. In the end she was on her knees and left there. On occasion the collar inflicted punishment to keep her conscious.

When the last of them left her, her hood of shadows dissipated. She had to endure matters for some time. Long enough for that sticky sap on the wall to fade allowing her to pull her hands free. Had she tried earlier it would have been with some difficulty. The sooner she tried the more damage she inflicted on herself taring off the skin if early on and simply pulling them free towards the end.

No one came for her leaving her in the dark now room. The bridge just outside that door.

Alexandra could not see much of anything to begin with so the additional darkness meant little to nothing for her. Her attention was more towards the cool seed drooling out of her anus only to be replaced by hot scaled dicks.

They were relentless, slamming into her while scaled claws held her hips and body in place. Alexandra had no control over her body anymore. Her eyes rolled back as drool escaped her moaning lips. She came when they came, squirting out around the toy while cum blasted deep inside her.

Her knees gave, forcing the lizard creatures to force her back up for the next one's turn. She had no strength left by the end. She did not try to pull herself free. Gravity eventually won out on the fading sap. Alexandra collapsed onto the floor, twitching and trembling as the toy continued to ravage her pussy.

The task was complete, Alexandra blacked out a final time, this time no punishment came. The vibrator continued to torment her depleted form. After so much exposure, the collar's work was done. Her brain would respond to commands appropriately even if the collar was removed.

She had been blessed with unconsciousness in one small way. With the toy still at work her unconscious mind had been tormented for a good while as her dreams were full of sex.

The hood of shadows had to be for her sake as far as concealing who she was. Clearly Scar knew as did the captain. Some of the crew may have too, especially any who had the large breasted agent before. There may be some uncertainty there. After some time her sleep had been dreamless.

When she woke it was in what appeared to be an infirmary. She had been cleaned up and while she was naked her robes had been nearby. There was some sort of medical droid here as well as Alicia who grinned at her. Encouraging her to eat to get her strength back up the second day was easier. It was a day of recovery. Outside of her typical massage she had been tasked with resting and given a datapad to familiarize herself with the ship systems again.

The following day had been business as usual getting back to her role in maintaining the vessel. There was not much to do. They were nearing their destination, wherever it was had been a little more than two days at a moderate cruising speed she imagined. The crew seemed relaxed for the most part but paid her little attention.

After she had finished calibrating the sensors Scar came to her again. He escorted her to a room near engineering. No one had been her, the excuse that she was to meet with Alicia brought her there and as soon as the door had been closed behind them he grinned at her.

It was easy to tell her apart from Alicia since she worked on the ship and Alicia went around without the robes. “We are nearing our destination. Alicia wishes for you to do a good job tonight. It's going to be special, I got a little something to make it easier to deal with. The question is do you have a little something for me?”

He had seemed to be waiting on her to react or respond in someway, the collar stood ready allowing for only a small delay she had learned. It had not been as advanced as other models as far as recognizing rhetoric responses and so forth interpreting everything as far as her responses went.

Being fucked to the point of needing extensive rest and possible medical treatment had become a norm for the enslaved agent. Of course, any orders were met with near endless stimulation and reward from the collar. Alexandra obeyed, eating, resting, and reading datapads. All was rewarded as the collar did not seem to care about context or purpose.

Alexandra's next day of work was interrupted by Scar. The reason behind the order to follow was irrelevant. Scar could have had no reason and the agent would have no choice but to obey. Every step she took brought pleasure rippling up her legs and bubbling inside her netherlips.

She did not know what the offer was but the collar demanded a response nonetheless. "What do you wish of me, Master?" Alexandra replied with her head lowered. She would have to tend to the shapeshifter one way or the other. If she got something that kept her alive longer in return, that could be seen as a blessing or a curse depending on a slave's state of mind at this point.

Scar lifted up her chin with a hand so he could see her features. He grinned, his eyes regarded the collar for a quick moment as if forgetting that she had been wearing it. He was quite familiar as to it's function. While many law abiders wouldn't know all the details even they would know of the basics. Suffice it to say that he was aware of some of the finer points.

She was eager to obey, the collar ensured that one way or the other. Either she wanted the pleasure it gave or wished to avoid punishment. He was aware that it was a basic model. He wasn't too familiar with how each performed differently but he knew that this was one of he older versions that he had seen. It would not punish her if he did not answer and would give her a small moment to obey before doing so once orders had been made.

“You can start by giving me a blow job,” he said after a moment. He didn't really have to think about it. There had been no sense in wearing her out a head of time so he let her use her lips, tongue and breasts. It took a while but she managed to get him off. He managed to prolong his pleasure a bit drawing out her own as the collar fed her even taking a few breaks her and there to collect himself.

In the end his biggest decision was where to cum. As appealing as spraying all over those tits or her face was clean up was a bit of a problem so he had her drink down his spunk. Satisfied after being cleaned off he gave her the order to stay her until she counted to a particular number or someone came for her, whichever came first. She didn't have to start until he left. He was unsure if her own arousal would settle by then not to be so easily detected by the crew or not. They wouldn't do much on duty but he wasn't going to take any undue chances seeing that he had an idea as how the night would go for her.

From his pocket he took out a small orange capsule. “This pill will get you so fucked up that you'll be able to check out of the worse of things. By fucked up I don't mean that it will damage you, just blow your mind.”

He grinned as he gave her the pill. “I'll most likely see you later tonight but I doubt you will remember. You can hide the pill under your tongue before you go see the captain. Any questions before I go?”

"Yes, Master," Alexandra replied as she fell to her knees.

She wasted no time as she took hold of the alien's phallus and proceeded to stroke. Her warm breaths soaked into the shaft as her lips came closer. She slowly parted them as the tip slid inside the woman's mouth. "Mph..." Her tongue swirled around as she brought more of the alien's manhood into her. The collar was already awarding her with pleasure while she began to suck deeply.

Alexandra gave Scar exactly what he wanted. Her head bobbed, taking deep sucks as she drew her head back and lathering the member with her tongue as she took him back in. His tip pressed against the back of her throat, taking as much of him as she could without choking. Her entire body tingled from head to toe as the collar continued its insidious work. Besides the occasional breath, Alexandra only stopped when Scar wanted her to stop, prolonging this moment as long as possible.

Soon, she was given his hot load and ordered to swallow the thick salty substance. Alexandra swallowed every drop and cleaned the alien off. The agent accepted the pill, uncertain of what Scar meant exactly by being 'fucked up'. "No, Master," she replied, "Thank you, Master..." The agent waited until he left before starting the count and returning to her duties. The act of counting sent pleasure through her body, doing very little to stave off her arousal. But, that was common due to the collar being active all day and night.

Each number she made it to brought pleasure, her own arousal growing. Rather than allowing her to calm down her situation only grew more intense. Her collar being a simple one took the command to count as any other command and in the end she came. The continued counting ensured that she came again and again and again.

It was fortunate that Alicia had been the one to find her, or at least more so then a crew member. She was pleasured again but the collar was no longer in effect. She had been left in the store room for a time and fetched later when it was time. Had she remembered the pill and actually took it there wasn't much she would remember from the night before. Vague glimpses of events that didn't seem real as if she was watching them unfold as a spectator rather than a participant.

Without the pill made little difference as the counting and Alicia did a number on her already. She had to endure both the captain and crew, one after another after another. Cum stained her body so much that all she could smell had been the spunk of these aliens.

She was tortured a bit. Later aches and pains would tell her where she had been whipped or shocked. She was fucked into oblivion and beyond. When next she came too a full day had elapsed. Her body covered in ointments and medicinal oils that dulled that ache a little.

There was a window in this room, they must have made it to a planet. No one was present in the white room and she had been naked beneath the sheet. Some folded clothes had been on a seat near the bed. Checking them out they were sexy, a low cut skirt and blouse that showed off her tits along with some under garments. All would actually fit well enough.

An IV had been attached to her, half depleted. Either medicine or food. There had been some chances to get some answers as a call button for a nurse had been here indicating that she had been in an actual hospital some place. From outside the room she could hear occasional movement and sounds of people coming or going as if she were in an actual hospital.

Alexandra took the pill after Alicia teased her already heated form further. The rest of the day was incoherent for the woman from then on. When the agent came to, the pain she felt revealed that she had a very long night with the captain and the crew again. Not knowing the details was probably best but that only left questions lingering about the source of much of aches and pains. There was also the matter that she woke up in a hospital bed with an IV re-hydrating her exhausted body.

With the IV attached, changing into the skimpy clothes seemed out of the question for now. The agent would not even check if she was still collared, not that it made much of a difference. At least the pill spared her the details. For now, she would try to rest and hope the pain faded in time. She was uncertain where she was but she could assume that Alicia would arrive with the details soon enough.
