Tooru had always been obsessed with aliens. Ever since childhood, he has watched alien documentaries, read articles, and watched many sci-fi movies with aliens. He had a bunch of plushies that had accumulated in his room over the years. To say he simply liked aliens was an understatement.
One night, after looking over an article about UFOs, he decided to step outside into his backyard for some fresh air. He had to be quiet when walking down the steps, due to the fact that it was around three AM.
There was a quiet breeze brushing Tooru’s face. It was calming. He looked up at the stars and spotted the constellation “Orion”. He was a fan of the stars too, someone who could spot almost every single constellation in the sky.
He took a deep breath, the cold winter air filling his lungs. He heard the sounds of cars passing by a few roads down. He had heard a weird whirring sound above him. Like any other normal person, he looked up. Above him, was a UFO. It was casting a green glow upon Oikawa’s face.
A blood-curdling scream tore from his throat — not from fear, but from exhilaration. It was his first time ever seeing a UFO. Without hesitating, he took out his phone to take a photo. That is, until he felt himself floating up into the sky.
“HOLY SHIT!” Tooru yelled, squirming in the air. He found that he was floating up into the spaceship. He felt a wave of adrenaline wash over him, as he continued to fly up. Tonight was his night — he would be one of the first people ever to be inside an alien spaceship.
He was ready to be a victim; ready for abduction.
Oikawa’s head felt dizzy and he felt lightheaded. He couldn't help but lose consciousness as he reached the entrance of the UFO.
..
When he woke up, he was in some extremely ultramodern cell. He wasn't chained up or anything, he was just held captive. He looked around and from what he could see, the ship had an extremely futuristic look. The room gleamed with harsh white walls, the black tiles reflecting sterile beams of light. There were also some huge, weird gadgets in some parts of the area where he was captured.
Soon, a weird-looking creature walked its way up to Tooru’s cell.
It was an alien.
Surprisingly, they looked similar to the ones that were in movies. Except, they had 4 arms and were an odd dark blue color. They had antennas on the top of their head, weird tentacle legs, as well as pitch black eyes.
The alien had spoken to Tooru in its own language and the brown-haired man couldn't make out what the creature was saying. That is, until a speaker with a translation started to play.
“Hello, human. We have you captive because we are researching the reproduction of humans and want to know if homo sapien males can reproduce human-alien hybrid off-spring.” the speaker spoke, the translation coming out with a robotic voice. It caused Tooru’s eyes to practically pop out of his head.
He was meant to be an experiment? He must be hearing things, he thought. But when the alien looked him dead in the eye, he felt cold sweat drip down his face.
The creature unlocked Tooru’s cell with a special card. It proceeded to grip onto the brown-haired man with two of its arms. It took Oikawa to a room.
For a heartbeat, his mind blanked, every nerve buzzing with disbelief.
The room was a lab, a lab full of humans, both men and women, each in a different cell. They were having sex with other blue alien creatures. This must be where he was gonna be experimented on, he thought. Great. Wonderful. Abso-fucking-lutely terrific. I am going to get forcefully get fucked by an alien to see if we males could reproduce a human-alien hybrid.
Obviously, Oikawa complied and didn't try to fight the alien. He would rather have sex with one than to potentially get murdered by one. The thought gave him the chills.
The blue-skinned creature threw Tooru into one of the cells. There was what he thought was a bed, at least.
Oikawa was sitting on the mattress patiently until a creature came up to his cell and stepped inside. He took a closer look at the creature and realized it was an alien-human hybrid. It had two normal legs, but still had the four arms. The alien was tall, roughly about 5’10.
“Hello,” the creature spoke, looking slightly intense. Tooru was stunned. The creature knew English? Forget that, this creature was very handsome, so much so that Oikawa didn't mind being an experiment.
“Hi,” Tooru responded, trying to appear friendly. “You were assigned to me, correct? Let's get it over with,” he smiled warmly, despite his heart practically pounding out of his chest.
“By the way, do you have a name by any chance? I go by Oikawa.” Tooru asked.
“I am called Alien 2457, or just Iwa.” Iwa responded, rubbing the back of his neck. He went and sat next to Oikawa.
“Why don't I take the lead for now?” Tooru smirked. He grabbed Iwa’s chin and kissed him. It was awkward at first, but they soon fell under a steady rhythm.
Oikawa was straddling Iwa, kissing his neck, and took off the piece of clothing the aliens had around their waist to serve as clothing.
To say Tooru was shocked was an understatement.
Iwa was enormous, thick in a way that made Tooru’s breath stutter and his body ache with want.
It was unlike anything Oikawa had ever seen. He couldn't help but become aroused at the sight of him. He felt himself grow hard through his pants.
The brown-haired man slowly stroked the Alien hybrid's cock. Iwa threw his head back a groaned. Oikawa took off his own pants and underwear.
This was the oddest thing Tooru had ever done. Having an alien run its hands all over his body felt so foreign, unlike anything he’s ever done with a human.
The lewd look Iwa had in his eyes made Oikawa’s knees weak. He was hypnotizing.
Oikawa’s slick hand pumped faster, each stroke wringing a throaty whimper from Iwa. He had thought that this creature would have had more of a dominant role, but he was so, so wrong. Feeling it writhe under him was addictive. He was keen to be fucked by Iwa, for it to fill him up.
Oikawa climbed on top of Iwa, and positioned his hole with the blue-skinned creature’s dick. He slowly sank down with a long moan. Iwa too, groaned very loudly.
Tooru slowly went into and up and down rhythm, while slowly stroking his cock. It felt supernatural — maybe even Extraterrestrial. Iwa’s dick was hitting all of his sweet spots, causing a knot to develop in his abdomen.
“Fuck,” Iwa groaned, digging his nails into the brown-haired man’s hips. That was definitely going to leave a bruise, Oikawa thought.
“Shit, im close, Iwa,” Tooru whimpered, playing with his nipples.
Oikawa was close to orgasm. He felt precum leaking from his tip and his legs starting to twitch. He saw that Iwa was close to cumming too, by the way his face contorted due to the pleasure.
He quickened his pace on top of Iwa, aligning it to the rhythm of his strokes. He continued at a very fast pace until he came. He threw his head back, groaning loudly as he rode through his orgasm. It felt as if he was floating. Not long after, Iwa bucked his hips and came inside of Oikawa with a low groan — filling Tooru with his semen.
Tooru collapsed on top of it and gave Iwa a light peck on the lips. “That was amazing.”
