Still swirling the taste of your cum in her mouth, Samus was raring to go. Both her holes, her ass and pussy, throbbed with excitement. As badly as she wanted to stuff you up her dripping womanhood, she knew she'd get a bigger reaction from you if you went up her ass. Besides, she hadn't felt a good buttfucking for a while, and was looking forward to giving her big booty some love. The only problem was her little friend was nowhere near big enough to fuck her on his own. Samus had a plan for that though, and promptly left the room. She knew you weren't going anywhere.

You were essentially paralyzed for the time being, still reeling on the table in extreme pleasure from the bounty hunter's potent fart. You hated it, but your body couldn't stop spasming in painful bliss. You rolled from side to side, frantically arching your back while gasping for breath. Your lungs could barely take in air, and what little you got was stained with the scent of Samus's gas. It took a few minutes for you to regain motor control of your body again, but by then it was too late.

Samus returns primed four torturing you once more. This time she had a different sort alien goo with her, it was bright yellow and contained in a large vial. She snatched you up in her hand and poured some of the yellow liquid on the table. Instead of explaining what the substance did like last time, she simply placed you on top of the puddle of slime and held your body in an upright position. The sticky goo went up to your ankles, before Samus took the vial and started to pour more around your legs. You tried to break free of whatever it was but the yellow slime became more dense by the second. Before long your knees-down were encased in a shell of hardened goop, the colour of which had turned from yellow to orange.

"Pretty great stuff isn't it? You can mold it into pretty much anything, but right now it's going to keep you stuck to that spot." Samus said.

With ease, she lifted her massive body on top of the table and turned around. She kneeled on the smooth surface, and looked back as she stuck her gargantuan ass outwards. It wiggled from side to side, getting into position directly above your tiny body. You cowered in fear below. Was this really happening? Samus's round butt cast a huge shadow from above, her two colossal cheeks loomed overhead ready to crush you again at any moment. Between them you could see her puckered butthole, still twitching with excitement. You looked deep into the sweaty hole and heard Samus speak, still keeping her ass pointed straight at you.

"I just gave you the best orgasm of your life, little guy. Now it's your turn to make me cum..."

Then she slowly began to lower her ass down on top of you. You were frozen in terror, your mind still processing what was happening. Samus, the legendary bounty hunter, was going to send you up her ass. The asshole that was right in front of you. If you went inside there it was going to be the end of you. The pain and smell of her ass would be too intense and your mind would surely break. She reached her hands back to her behind and spread her twin globes apart, her fingers digging into the soft butt flesh. She was giving you a clear view of the dirty hole that was about to eat you. With the orange goo holding you in place you realized how you must look right now. You were going to be her dildo, her fleshy, struggling anal dildo. You weren't even a person anymore, you were just a tool for pleasuring her ass.

"P-Please..." you begged softly "Don't... don't send me up there..."

Your only response from Samus was her wet asshole being planted on your face. The puckered anus was slick with the woman's runny pussy juices, which acted as lubrication. Your neck was bent backwards by the overwhelming weight of her butt, and your head began to sink into the wrinkly pucker. It was hot and sticky, and still wafting with the stench of her rank farts. If being pressed into the rim of her shithole was this bad, you couldn't imagine how bad it was inside.

Samus had her eyes closed and smiled as she wormed your head into her butthole. It pulsated grossly, expanding and contracting like some sort of horrifying mouth. It was an accurate comparison, Samus's huge anus was starving, and had been waiting to devour your body for some time now. The fleshy hole was slurping on your skull, eager to gobble you down and chew you up inside. You cried as the giant anal wrinkles rubbed themselves all over your face, filling your gasping mouth with a mix of hot sweat and juices. You shouted as best you could for mercy.

"PLEASE-!"

SLORP! Samus pushed down with her butt and sent your head all the way inside her. You screamed, your vocal vibrations caused the hot pucker to shudder around your neck. The flesh inside her ass was blazing hot and wrapped firmly around your head. The stench was horrible, it made your stomach turn while your dick became rock hard. Samus leaned further backwards, gradually feeding the rest of your body to her hungry depths. The anal maw gorged on your torso, then followed with your hips. Slowly you slithered inside her ass, passing through the tight muscles of her sphincter into the more spacious area of her rectum. The atmosphere inside Samus was beyond foul, the air tasted of pure shit and burned your lungs again. You felt your mind start to slip. The blistering sensation made you moan with delight and start to writhe around.

Outside, Samus's spread asshole had eaten all the way past your legs and reached the hardened holding goo. Your body was completely inside her, no longer visible to the outside world. Feeling this, Samus let go of her ample butt cheeks and let them slap against the table. She sat there for a moment and reveled in the strong tingles you were making inside her butt. Focusing her ass muscles, she squeezed her bowels hard around your body, like she was pushing out a turd. The squirming tingles stopped for a moment, before they returned again with added enthusiasm. Samus drooled with ecstasy, moaning like a young girl in heat.

"Mmhhhhhnn~! You feel so good inside my ass!"

You found yourself being suffocated by the powerful cramped walls of her butt. Like a snake, they coiled around your body and forced the air out of your chest. You couldn't stop yourself from wriggling against her slimy muscles, which made the sensitive flesh squeeze even harder. The loud moans coming from the giantess above were muffled by her butt meat, and almost completely drowned out by the sickening noises echoing deep inside her bowels. Wet squelches filled the chamber as her undulating walls massaged your body, wrapping you tight with a juicy embrace. Her dark pit throbbed and pulsed before finally releasing its grip on you.

Samus was panting a little. You were small, but felt way better than she expected. Planting her palms in front of her for support, she slowly started raising her hips. Your tiny body slid out the dank hole, sticky threads of anal juice stretched across your exposed skin. The anus went all the way back up to your shoulders and stopped, keeping your head inside. Samus's asshole was relaxed and breathing. Faint bits of light entered inside the gaping hole, illuminating the humid bowels. You could see her red walls quivering in anticipation, ready to swallow you again. Beyond that the oozing cave led into a deep darkness, one that extended into the girls very core. The view filled you with dread, right up until the moment Samus started to push her massive ass back down into the table and submerged you in darkness once more.

Lubricated by her anal juices, you slid back inside her booty smoothly. Picking up the pace, Samus forced you all the way up her heavy ass and then immediately started to drag you back out. This was it. She was going to start fucking you like a dildo now, and there was nothing you could do to stop her. Moaning, she sped up her steady hips into a gradual rhythm. Your slow sliding within her ass escalated into a rough pounding, driving you face-first into the hot pumping walls. Splashes of anal juices cascaded from her depths into your mouth, filling your gasping throat with the taste of feces. Savagely she rammed you into her bowels, your head was used to force the thick throbbing walls apart, over and over again.

The tightest part of her ass was definitely her cramped anus. The ring gripped you with incredible strength, crushing your body as it went up and down your form. Repeatedly, you were squeezed inside her putrid anal tube like toothpaste. It felt like you were going to burst at any second. Her sensitive pucker quivered, loving the feeling of fucking your squishy body. Every time it passed your dick you winced, the pressure from her asshole felt unbelievable. You tried to compose yourself but it was impossible, and after only a minute of being fucked you came.

Samus didn't notice your orgasm or care, she was too busy working on her own. Her pussy leaked juices onto the table, raining droplets on the shiny surface one thrust at a time. She leaned back into her sex toy, and changed positions from being hunched over to drilling you straight up her back. Bouncing her huge booty on you from this angle felt wonderful, it made her shout out loud with each thrust.

"AHHN! YES! YES! YES! GET! IN! THERE!"

The heavy thumping of her ass hitting the table over and over was intense, it shook you to your core. Her movements got rougher, but she still wasn't ready to cum yet. You, on the other hand, had already cum multiple times. The excruciating pain and rank stench were being converted into pure pleasure thanks to that green alien extract you drank, and her hard ass-fucking kept you in a constant state of ecstasy. Had the stimulus been different cumming this much would have felt amazing, but because you were being raped by a giant shithole it made this whole ordeal a life-scarring experience. You screamed for her to let you go free, but your voice was lost in her deep dark ass-cavern. It was overpowered by the wet squelches surrounding you and the sexy muffled groans outside.
