Arthur wasn’t entirely sure what to expect when he was given the go-ahead by his partners to come down into their living room. He had known what was going to be happening vaguely, they weren’t stupid enough to try this kind of thing without a clear set of parameters and a plan for what aftercare was going to look like.
Still, that didn’t stop him from gaping at the large pink tentacle suction cupped to the ground where Liv’s modern coffee table usually sat.
The aforementioned furniture had been placed over to the side, and it looked like it was already stocked with the water and snacks that Arthur had requested for the post-scene care. On top of that, there was also a sheet on the ground around it, which implied that things were going to be getting significantly messier than he was used to. He hadn’t ever managed to squirt the way that Hill and George had, but to get something of that size inside of him he was going to have to use an obscene amount of lube.
He closed the door to the entryway behind him and then shuffled towards the dildo. He grasped the front of his t-shirt for a moment before he finally pulled it over his head and began to fold it up so that it could be deposited where he had been instructed to put his things. His backpack went on top of his clothes once he had finished stripping, leaving him standing in the chilly aircon cooled air in nothing but his boxers and confidence.
“Jesus,” he whispered to himself as he stepped onto the sheet and then fell down onto his knees. He had been training for this all month, since Isaac had brought up wanting to do a strange little scene.
Truth be told, he’d been gaping in more ways than one when he walked into the living room. He had just removed the last of the plugs that Liv had given him in the training set and he was so open, waiting for something to fill him where there was now a massive voice. He was just getting a bit worried that his eyes were larger than his cunt now that he could actually touch the toy that was supposed to be going inside of him.
When the door opened to let the other two occupants of the house in, he only spared them a passing glance. He had to look back at them twice before he really comprehended what they were wearing. Liv had a sense of humor about her even when it came to sex, it seemed, because she and Isaac were dressed in their regular streetwear with matching white labcoats over the top. They also had little name badges with what looked like puns Arthur couldn’t be bothered to read next to their photos like they actually worked in a research facility somewhere.
“Oh, I see that they’ve already dropped the specimen in for us,” Isaac said as he sat down on the couch. He was right behind the tripod, which had the same camera that they used to film their videos together perched on the top. Arthur had expressed his worries about crossing work and play like that, but Isaac had informed him it would remain off the entire time.
“What do you expect? We’re a top notch research facility here,” Liv sat down and crossed her legs with her perfect, prim nails tapping on the edges of her hands. “Species of this kind procreate synthetically every time?”
Procreate.
They hadn’t talked about that part, but he supposed that was the only reason that scientist would be observing him getting himself off like this. He watched them out of the corner of his eye while he dragged his hand up and down the dildo repetitively. He could feel the ridges on one side and the perfect lines of faux suckers on the other. It would feel so, so good inside of him just like his partners had assured him that it would.
“So we’ve heard, we’re watching to see if anything takes or if this is similar to the behavior found in dolphins on earth,” Isaac replied. “Remember not to talk too much.”
“Of course,” she cleared her throat and adjusted herself a little bit so that she could get a better angle of viewing.
Arthur was going to give them a show, it was what they had requested from him. He rose to his feet and turned to the side of the living room that held all the windows, which had been closed so that no one could see the debauchery happening inside the little apartment. He dipped the tips of his fingers into the waistband of his pants before he pushed them down and down, until the fabric was pooling around his ankles and he had given the couple on the couch a full view of his wet, aching pussy.
He then knelt on the sheet again and made his way back over to the dildo. He stayed facing towards the windowed wall, mostly because his cheeks were already beginning to heat with the embarrassment of what he was doing and he couldn’t bring himself to turn around and face his partners. His hand grasped for the head of the long dildo, which he brushed his thumb over once he had wrapped the rest of his fingers around it. His breath came out shaky and unsure as he brought the dildo down to his folds and traced it from opening to clit, and then back again.
He was already quivering with the need to be filled, to have some kind of stimulation on his aching erection. His t-dick was jumping every time that a new place on his pussy was touched by the silicone.
“Do you think that we need to tell it that it can use lube? I don’t want our only specimen to get hurt,” Liv’s voice reminded him patiently and in-character that he did need to add something else to the tentacle lest he hurt himself, despite how horny he was.
He scrambled for the bottle that she had left at the edge of the sheet and then turned around so that he could face them for only a moment. He flipped off the cap while struggling with the slickness of the bottle for only a moment, before he turned it upside down and applied just enough pressure to spread the lube over the thing that was going to be inside of him very, very soon.
“Don’t underestimate it’s intelligence, doctor,” Isaac replied plainly. “Though I have to say, I can’t help but notice the way that you’re squirming. Are you aroused by the idea of it fucking itself on the dildo?”
“I might be,” Liv replied.
Arthur’s hands wrapped around the base of the dildo and held tight to it as he traveled up, collected some of the lube, and then spread it down onto every inch of the pink-colored suckers. He watched them both with wide, waiting eyes while he let himself get lost in the story that they were making for him.
They kept referring to him as an object, like he wasn’t even something that deserved a proper gender designation or a name. He was simply the specimen, something that they had found out in the wilds and brought back to a research facility so that they could study what the extraterrestrials of the galaxy were like. He was unknown and unhuman to them, and he loved it.
“Are you thinking about what it’ll need to deposit its eggs into once it’s finished creating them? We might be able to get you in on an experimental roster to see if it can breed with humans,” Isaac’s hand was resting on Liv’s leg and then slowly traveling up to her cunt.
Arthur interrupted the moment that they were sharing with each other by pressing the head of the tentacle to his opening once more. When the tip breached him, he clamped down around it despite how stretched out he was. He gave a shuddering moan and then forced himself to relax so that he could take more and more of it into himself.
The fact that it tapered from nothing to almost a full fist was the best part of it, because Arthur could feel the way that his pussy lips stretched open with the more he took of it. His walls throbbed around the dildo so that he was intimately aware of the ridges and faux suckers, the textures adding to the pleasure for him. He whimpered only when he felt the tip reach the apex inside of him where it could go no further, but then it curled forward inside of him.
Suddenly he was stretched so far, and so full of fake cock that he felt like he was going to burst. He brought his hand up to his belly, which had pouched out just a little bit with the addition of something where there had previously been nothing. He could imagine the tentacle helping activate the part of him that grew eggs, which he could deposite via ovipositor right into Liv like she was squirming at the idea of. Maybe he could convince her to do a scene like that in a little while.
For now, all he could do was stare ahead at the couple on the couch while he began to ride the dildo with everything that he was. His thighs and calves burned with the effort that it took to rise into the air before plunging back down and filling himself with the maximum amount of tentacle all over again. He threw his head back and gave a whimpering, groaning moan that made him feel like a real alien. He had never made a sound like that before, had never been so full and contented in the way that he was.
“Do you think that it knows it can cum?” Liv asked. “Or do you think that it needs something else?”
The fuckers had pavlov’d him when he first got together with them, because the moment that she even so much as implied that she was giving her permission for his orgasm he felt it wash over his body all at once.
Arthur leaned forward so that he was braced with his elbows and knees on the floor as his body clamped down around the folded over dildo inside of him and cummed as hard as he had in a long time. He felt the long, flaccid tentacle squirming out of him while his walls clamped down around it. For the moment that he maintained some semblance of lucidity, he wished that they had purchased one that could cum into him so that he could have a bit more of feeling full, and so that he could leak thick white goop to complete the scene.
When he came back to himself, he watched Liv walk around the sheet to the telly while Isaac closed the camera up. “Right, we’ve gotten the footage that we need. We’ll check to see if it activated the eggs and if it has, we can talk to our directors about having you be a carrier for them.”
He gave a strangled little moan and Liv laughed, “I think you’re going to make him cum again, Isaac. He’s too scientific, hes getting off on you talking like you’ve got an experiment to run.”
“I told you he would,” Isaac joined in with her laughed before he knelt down beside Arthur. “Hello, you weirdo. You ready to have a bath and some snacks?”
“I’m the weirdo? You and Liv are the ones that suggested I fuck myself with a tentacle while you watched,” Arthur mumbled. He lifted his limp arms up as much as he could so that Isaac could pick him up, his body sticky with lube and sweat, to bring him to the bathroom.
“But you’re the one that agreed to it without even arguing about how big,” Liv replied. She kissed his nose and then set about cleaning things up for their proper aftercare hour.
