Compulsory modifications

Riley opens his eyes, but unable to move his body. Lifting his head up slightly, he sees that his arms and legs are spread out and strapped on a table in the centre of a massive operation theatre. Dozens of mechanical tentacles hang from the tall ceiling, with strange and complex tools extended from their ends.

After the AI had accepted Riley’s command, it instantly began the operation to merge Riley’s body with the extinct creature’s mana crystal. The first shot was a **** to put Riley to sleep so that he doesn’t have to experience the gruesome cutting and genetic modifications while awake. However, the next part is the most crucial, requiring Riley to personally perform.

Realising his situation, Riley opens his mouth. “Why the hell did you start…!”

Without giving Riley a second to speak, a large syringe stabbed into Riley’s belly button causing intense pain and tears to run down his face. Strangely, the pain briskly fades, replaced with a tingly and hot sensation between his hips and deep inside his abdomen.

“I apologise for any inconveniences; however, this operation must be performed quickly as managing your safety is my top priority. The backlash if it were to take too much time would be disastrous.” Said Shelly.

“Mmgh… Aah!” Muffles Riley in reply.

At this point, Riley could barely focus on the voice speaking in the background. It took all his all to distract himself from the burning sensation between his legs. Hot sticky liquids flowed out of his vagina, running down between his bottom and eventually drips onto the operating table. His breasts felt so lonely without being touched that the erect pink nipples sitting atop throbbed with every heartbeat.

Then, the most unimaginable thing happened that if Riley had not seen with his own eyes, he wouldn’t have believed it.

“This serum will fully activate the absorption process which utilises your body’s affinity to plant elemental particles~”

Although most of Riley’s view is blocked by his breasts, a large hole forms around the front of his tummy from where his belly bottom used to be. Seconds later – which seemed like hours to Riley – thin green vines grew out of the hole in his tummy, wriggling towards the air like an octopus’s tentacles. The vines then wrapped tightly around his whole body, touching all the parts that needed to be touched, bring Riley to his third orgasm.

“Ah!”

“Host is ready to absorb foreign mana crystal.”

A shiny fist sized stone with a violet lustre descends from the ceiling on the end of a robotic tentacle. Something about the stone made Riley focus in on it, unable to look away. Deep inside, a feeling edges a recurring thought into his mind: engulf it… make it mine…!

As if they were always a part of his body, with his intentions, the vines around his body wriggles in reach towards the direction of the crystal in the air. Like a shameless junkie, about to get their hands on their next dope, the vines’ wriggling intensifies as the distance to the crystal becomes smaller.

When the crystal finally reaches Riley, his eyes emit a green glow and becomes bloodshot. Countless vines envelop around the violet crystal, digging their roots inside. The ones that first met the energy inside the crystal turned black and fell dead. Nonetheless, dozens more replaced the gaps created, until eventually no more vines died.

With the last of his energy to stay conscious, Riley sees the vines bring the crystal inside his body through the hole in his abdomen, then he passes out.

He is falling into an endless dark void. Severe vertigo assaults his senses, everything starts to spin around him like falling into a deep dream, so he closes his eyes.

Once he opens them again, this time the spinning stopped, and he is near the rocky walls inside a large cave. The air is warm and moist; sounds of dripping water can be heard in the distance. All around him are mounds of black, slimy tentacles, tightly stacked and slithering slowly.

Riley flinches and tries to move away, but he is unable to. He notices that he’s back in his original male body albeit he’s floating and his whole body is semi-transparent. Underneath him is a tentacle creature that’s shuffling towards the direction of the water sounds, and wherever it went, Riley floated with it.

Gradual time skips outlined the course of this creature’s life and Riley realises that he is only a spectator, seeing parts of its memory.

One of the most impactful and clear events is when the tentacle creature arrived at a large Frawnian city. Others of its species had already captured dozens of people and are harvesting them by extracting their sexual fluids, regardless of their gender.

Joining in with terrorising the city, showing outstanding proficiency, the tentacle creature underneath Riley grew faster and stronger than the rest. From all around, moans of pleasure and endless orgasms and ejaculations brought Riley’s libido to an all time high. “When did I become such a sexual deviant…” he thought.

Through many thousands of years, the members of this creature went into hiding, but slowly died out as they were relentlessly hunted down by knights and sorcerers. Riley’s creature lasted longer, but eventually perished under the same fate.

*** Author's note ***

I really dislike how fucked up this chapter's gotten; it scared me when I re-read it. I thought "What sort of crazy psychopath can even come up with this stuff?"... And it's me. So I'm planning to completely redo this chapter into something 'more comfortable' when I have time. Also I'm currently working on another gender bender skinsuit novel which came to me in a dream ¯\_( ͡° ͜ʖ ͡°)_/¯.

P.S. Sorry if this chapter scarred you. m( _ _ )m
