Chapter 2: Processing
I awoke later, still held in place by the sticky tentacles, the lights having dimmed significantly so that I didn't wake. My cock and balls were free, but my ass once again gripped a tentacle, though much smaller than before and avoiding my prostate entirely. I wiggled and it felt like it went in pretty deep. Still held to the wall of tentacles, I wondered what the aliens wanted with me.
When I was starting to feel more wakeful, the wall of tentacles released another puff of pink gas, which made my head swim and my eyelids droop. I felt the tentacle in my ass thicken slightly, as if detecting that I could suddenly feel it much more distinctly. Across the room, the door dilated open and the slender alien entered once again. He carried a handful of rings with him as he floated across to me, long dick streaming behind him.
He gently grabbed my balls and massaged them downwards, like he was examining how far down they could go. He slipped one of the thicker rings around my ballsac, and touched it twice on the outside. The ring contracted gently around my balls, not tight enough to cause any discomfort, but enough to ensure it could not slip off, though the thickness remained the same, about two fingers thick. The pleasurable feeling of my ballsac being tugged on caused me to moan in pleasure, and the tentacle up my ass writhed as if happy about it.
Satisfied with his work, the alien then grabbed a much smaller ring and pulled back my foreskin to slip it over the head of my cock, resting it behind the ridge of my glans and over my frenulum. Thinking this ring was going to contract like the last, I braced myself. But when the alien tapped on the cock ring, it instead got warmer and lit up a soft yellow colour. I could feel it tightening, and then my penis began to tingle as it began to merge with my very flesh. After a few seconds, the ring had embedded itself under the skin of my cock, just barely visible, as it had conformed to the shape of my dickhead. The yellow light of the band blinked once and then went out.
The thin alien then grabbed my cock and started to jerk me off with one hand while he massaged his own dick with the other. Our penises both hardened, and I felt the weight around my balls as they flew up and down with the jacking of my hard dick. Recognizing that I had an erection, the dick ring started to glow a soft pink colour, just barely visible under my skin. It appeared to have expanded as my cock thickened, matching the size seamlessly.
Satisfied, the alien reached up above me and pulled out a thin, pink tentacle. The alien didn't seem to have any issue gripping the tentacle despite the coating of slime, even as the tentacle wriggled slightly in a circular motion. The alien brought the wriggly tentacle to my cock, and the ring turned a purple colour just as the tentacle seemed to sense it was there, encircling my dickhead and moving towards my piss slit. Covered in slime, the tentacle had no problem pushing its way into my dick and down my urethra. My cock throbbed as it felt the wiggling, and I moaned loudly.
The alien slid my foreskin up and down as I felt the thin tentacle poke further and further into my body through my stiff cock. My balls swung back and forth, providing waves of pleasurable sensations all the way up my spine. I could feel the tentacle still slithered up my ass thicken around the base, stretching my hole, and I instinctually tightened my hole back on it.
This combination of sensations was enough to start the flow of precum from my cock, which caused the tentacle inside of it to reach even further towards my prostate. With a popping sensation, it made its way in, and expanded the tip to stay lodged inside my prostate. That's when the alien released my cock and reached up to squeeze the root of the pink tentacle that had slithered down my dick hole. The thin tentacle then started to pump something into me. I could feel the pressure it added to my prostate, and it immediately made me even hornier. I wiggled my ass down on the tentacle in my hole, and it responded by thickening slightly and starting to slowly rub against my bulbous prostate from the inside. The pleasure was mind-blowing, and I threw my head back to yell out in ecstasy.
After watching me ride the sensation of my prostate being filled, the alien once again squeezed the root of the thin tentacle and it stopped its flow. The tentacle then made itself thin again, and released its hold on the inside of my prostate, slipping out easily and without letting anything escape behind it as the alien pulled it out of my cock. The alien then pulled a tentacle on the wall, and my legs were pulled upwards again, spreading my cheeks so that the tentacle in my ass would have unobstructed access to my lubed up hole.
The tentacle started fucking my asshole sensually, really working it over and writhing against my swollen prostate as much as it could. Once I was really getting into it, I could feel the tentacle get even thicker at the base, and started to stretch my asshole out like it did last time. Now that it was thicker, I could feel the sweet sensations all the way up my cock through my worked-over prostate. I was leaking precum like a faucet, and biting my lip.
Just as I was getting close to cumming, the alien squeezed the tentacle going into my ass and it contracted, returning to its normal size and slithering out of my hole. It was left open and gaping, and I could feel how worked over it was as I opened and closed it, hoping the tentacle would be returned to fuck me some more. The alien then left the room, and the beefy alien from before took his place.
Luckily, the beefy alien's giant cock was already rock hard and looked to be slicked up with slime, so when he walked over and shoved it directly up my waiting hole, he was able to go right to the base without a problem. I felt his big alien balls slap against my ass and lower back as he slid his big grey veiny cock in and out of my gaping hole, bringing pleasure to my anus with each thrust. Suddenly, much quicker than the first time, the alien tensed, his cock engorging for a moment, and he filled my guts with his cum.
