    This is a story I wrote in collaboration with a user on DA, who commissioned me to make the pictures you see here. Enjoy :)


    The newspaper ad had looked too good to not respond. A company was looking for test subjects, and they wanted to pay 500$ for clinical trial participants. The new drug was for stamina enhancement and they talked about “real life condition tests” to check its effects.

    When Rocky had arrived he was greeted by two stunning looking nurses. They seemed a bit on the muscular side, but their melon size breasts looked natural. When they told him that they would be assisting in his coming experiment he instantly knew whatever came next would be totally worth it.

    They gave him some paperwork to sign, which he only glanced over. Especially after reading “might enhance sexual characteristics” under “side effects” he didn’t want to wait any longer.

    They brought him into a treatment room, had him undress and lay down on a table. They didn’t comment on his by then half erect penis, and gave him an injection. After a few minutes Rocky felt his dick becoming bigger and harder. But when he had tried to push himself up to check, he couldn’t really move his arms. He wanted to say something to the nurses, but his mouth didn’t want to work either. Panicking he looked from one to the other, but they were just grinning to each other and said “It seems you are now ready for the ‘experiment’”.

    Effortlessly they had picked him up and carried him to the next room. A large cube with white tiles on floor and walls, and a big machine in the middle. They strapped him onto a bench in front of the machine with his still hard dick and balls secured through a hole. Then they stuffed his arms in an armbinder on his back and unceremoniously worked a large butt plug up his ass. Then they just stood there, holding him upright and waited.

    Rocky looked the machine over. It was carrying some rubbery, skin coloured thing in the middle of its six arms. In front of him was a blank screen and, worryingly, a big dildo right in front of his mouth.

    While he was still trying to get a handle on his situation, a door on the other side of the room opened. A stunningly beautiful woman in high heels entered. One of the nurses said “Everything is prepared doctor and the paralysis is starting to clear.” With that, the nurses let go of him and left the room. Rocky had problems holding himself upright, but it worked better than what he would have expected 5 min earlier.

    The doctor looked Rocky over “We are about to start the experiment. The drug we gave you, will give you a rock hard erection for at least 6 days. Also your refractory period after orgasms will be down to minutes. As a side effect, you might have your penis size increased…” Rocky didn’t understand why they bound him up for that, he would have tested that drug any time of the week. “… also your chest size, or properly I should call them ‘breasts’ then.” What…?

    “These side effects are most likely caused by the drug interacting with large amounts of sperm. This is what this experiment will test for. For efficacy reasons you will provide the sperm yourself.” Rocky couldn't believe his ears; they wanted him to drink his own sperm? He wanted to say something, but his mouth wasn’t working yet.

    “That is where this nice machine comes in. I call it an ‘oral replicator’. What it does is replicating your oral movements. So while you will give the dildo, which is exactly the size and shape of your own cock, in front of you a nice blow job, the machine will replicate everything on your cock down there. That includes lip and tongue movement, pressure, saliva, everything. So basically you will be able to blow yourself and make you cum, isn’t that nice? The sperm you produce will be fed back to you through the dildo. Quite the feedback if I do say so myself.”

    Rocky’s mouth started to work again, and he began grunting in protest. “It is all a bit exaggerated just for extracting and feeding you sperm. But it is also a good training for a new oral slut. After all, these experiments are expensive, and I need you properly trained up, so you can earn me my money back.”

    This woman was crazy. Rocky opened his mouth to shout at the “doctor”, but his words were transformed in a yelp, when the plug deep in his rectum gave him an electric shock. Confused he was looking at the mad scientist, but before he got any word out, he got shocked again, stronger this time. “Better start performing; otherwise the shocks will only increase in intensity. If you don’t want that, put your mouth where it now belongs.”

    A third shock, stronger still, had him hastily put the dildo in his mouth. Actually he had bitten down on it a bit, a fact he realized immediately as the machine did the same to him. More surprised than actually hurt he gave another yelp and promptly got shocked in the ass again. Quickly he put the dildo back in his mouth, more gently this time. The machine replicated his movement; it was a weird feeling as he experimented with slow movements of his head and tongue.

    “Better hurry up a bit. You have 10 minutes to make yourself cum. If you don’t manage that, you will get shocked again. No point in training an oral slave that takes too long with the clients. They are paying per load after all.” Only then did he realized the screen in front of him had lit up, showing a countdown ticking down.

    He gave the disgusting task his best. Of course he had received a few blow jobs in the past, but never had he sucked another dick, not even an artificial one. It was all too strange. After 10 minutes he had started to forget what he was doing and concentrated more on the sensation on his own dick.

    He was brought back to his current situation with a strong jolt up is backside again. He probably would have screamed if he wouldn’t have had the dildo half in his mouth that moment. The clock in front of him blinked “0m 00s” for a second then reset to “1m 00s”. So he didn’t make it in the time limit, but the shock has bought him another minute. He redoubled his effort, but still didn’t make it. At the end it took him quite a few more “extensions” until, with the highest speed he could manage, he made himself cum with 10s on the clock.

    Relieved he relaxed with the dildo in his mouth, until a second later a load of cum shot down his throat, which made him cough and lose the dildo. Of course this brought him another shock, so he quickly put the dildo back in his mouth. He watched disbelievingly as the clock went back to 10 minutes and started counting down again.

    He starred at it for half a minute, not moving, and promptly got shocked again, even while his lips where wrapped around the latex shaft. So not doing anything was discouraged as well. He started sucking again, what else could he do? Interesting enough, while the machine copied his movement, he didn’t feel any hypersensitivity; in fact less than a minute after cumming he already began pushing himself towards the next orgasm.

    This time he finished in less than 10 minutes. He even was prepared when the warm cum shot in his mouth and managed to swallow it. He didn’t car for the taste, but he had actually imagined it to be worse. Without much of a brake he kept going as the clock started its merciless 10min countdown all over again.

    ...

    He had lost all sense of time, didn’t even know how often he had already cum. The number was right in front of him on the machine’s screen, but his ecstasy filled vision was too blurred, his fuzzy mind to consumed by his task to make sense of it.

    He only remembered fractions of the last 5 days. He had sunken more and more into his task, pushing himself from orgasm to orgasm until they had become a blur, some seemingly continuous wave of pleasure he was riding. He had gotten better and better with his technique as well, had taken more and more of the offered dildo into his mouth and the machine had rewarded him by doing the same. The first time he had managed to push all of it in and down his throat so his tongue was touching his balls, his orgasm was so strong, he had spaced out completely. It had taken two shocks of the machine to bring him back enough to remember to continue his task.

    His body felt strange, heavier in the front and back. At the same time the dildo seemed to grow. He felt hotter and hotter. The orgasms should have reduced his libido, at least temporarily, but instead with every single one he felt turned on even more. At the beginning he didn’t like the taste of his own cum. Then he thought he had grown accustomed to it, but after a while realized, she actually liked it. Now she couldn’t get enough. The taste and feel of it in her mouth and down her throat gave her waves of pleasure, even stronger than the orgasms that came just before.

    The doctor came back to check on "him". She was slightly grinning to herself as she spoke softly into a voice recorder: “Subject under the drugs influence for 5 days now. He or maybe better she is fully concentrated on her task. Sexual characteristics have increased significantly, at least 50% on the genitals and even much more on the breasts. She seemed to have grown addicted to her cum, to the point where getting more seems to be the only thing on her mind. We will have to make a test if that is translatable to other sources of cum. As it is she will be a very good working horse for the lab, at least as long as the effect hold and there is no sign of them diminishing. She should probably get a more suited working name, Roxann sounds good.”
