Lucy was enormous. She was nearly eight feet tall, with the voluptuous proportions of a Greek Goddess to back it up. She had long, straight blonde hair and large green eyes, with the kind of angel's face that didn't seem altogether human. She wasn't.
Her breasts were round and full, each tit bigger than his head, probably bigger. The sharp, turgid points of her teats poked out from her tight latex catsuit, and suddenly James felt his cock harden and swell before conscious thought entered his mind. Her legs were impossibly long, ending in two high-heeled pumps that made her seem even taller. She looked like the true epitome of the female sex, with the kind of curves that could bring any man to his knees just by looking at them. James certainly felt that way, but he was frozen in place, too scared or astonished to move as she stepped inside his hotel room and locked the door behind her.
James was instructed to wait naked, on the bed, curled up in a fetal position. This was his first time with a dominatrix, and he knew there were a lot of surprises in store for him. What he didn't know, however, was that she was a space alien from a planet that specialized in the milking of captured male specimens.
Lucy opened an airtight metal canister. From it she produced a pink-colored slime putty which stuck to her fingers in a way that was nearly autonomous, as if it had a brain of its own.
"What--what is that? What are you doing?" James said, struggling to turn his head sideways from his prone position.
She only giggled as she pulled out more of the slime; a lot was packed in there. Between her hands she held up a wide, thin blanket of the stuff, the slime rippling and contorting with a lascivious sentience that was eager for its next meal. Her latex gloves masked her scent; without them, the slime would have attacked her. Instead, it hungrily stretched towards James's exposed back.
She threw the blanket of slime over James. He gasped, tensing up as it draped over his neck and shoulders. Then she rolled off of him, eager to watch the unfolding spectacle from a safe distance. This was always her favorite part of the job. She licked her lips and waited.
The blanket of slime began to spread all across James's backside until it had nearly covered the entirety of the mattress, thick tendrils firmly attached to each corner of the bedpost like the corner weights of a large net. It had effectively flattened him against the bed, and Lucy couldn't help but smirk as James began to uselessly buck and thrash his weight in a futile attempt at escape. It was no use; the net was too strong. He let out a moan of exhaustion.
A thick node of pink slime coagulated near his buttocks until a small tentacle formed. Curiously, it circled the rim of his butthole as if searching for a way in. James let out a whimperish gasp as it slipped inside of him; he could feel it pulsing and throbbing in him, massaging him with an inhuman dexterity that made his legs go numb. It soon found the little walnut-shaped gland that was his prostate, coiled around it, and began to vibrate.
"Oohhhhhhh!" James mewled involuntarily, and Lucy grinned. The slime was starting to have its effect on him.
James's fingers gripped the bedsheets until his knuckles turned white. He lolled his head, both out of a pathetic sense of rebellion as it was from inconceivable pleasure. Lucy watched as his backside writhed in the little space he had, trying to force out the clever intruder that was designed to find his deepest pleasure centers and break him--physically, emotionally, sexually.
If he didn't escape now, he never would. James let out a roar of exertion as he began to climb onto his knees. Against the luxuriantly soft mattress, he might as well have been swimming against quicksand. Still he managed to work himself onto his knees, buttressing his backside against the slime net. Lucy was impressed; she didn't know James had it in him, but that was as far as he could go.
James was stuck in a more humiliating position than before. His butt stuck up in the air, his balls dangling loosely between his thighs. His head and arms were still pinned down. "Urrghhh!" he screamed. The slime net became only tighter, immobilizing him with an almost sadistic strength as the net redoubled its efforts and pushed his face into the mattress.
"Enjoying the view, slave boy?" Lucy said, stepping in front of him and pushing her chest out. Beads of sweat rolled down James's brow. His face was masked in a hot blush of exhaustion and arousal.
"Fuck--" he panted. "Fuck y--nnnnnhhh!"
James shuddered violently, his eyes rolling into the back of his skull as the tentacle pump-fucked him so rapidly that it became a blur. A long, syrupy string of precum drooled out of the tip of his cock, which swung beneath him like a large pendulum.
"Still think you're so tough, huh?" Lucy said. "Well, let me change your mind."
Lucy circled around the mattress, not failing to notice James cast a wild, panicked glance at her that she pretended to ignore. He wasn't going to beg... not yet, not until he had been reduced to the hot, whimpering mess she needed him to be. She pulled out another canister of pink slime from her duffel bag and unscrewed the cap.
James was so busy concentrating on the strange, explosively pleasurable sensations that were squeezing and milking his little prostate that he hadn't noticed the gloved hand reaching under him, a thick slab of pink slime on its palm. Before he could react, Lucy had stuck it against his cock and balls, and the pink slime awakened.
He felt it form a ring around the base of his cock, preventing him from ejaculating no matter how hard he tried. The firm constriction was not uncomfortable, but the pressure was something he'd never experienced before... it reminded him of one of those blood-pressure cuffs that you used at the doctor's office. The pink slime formed a hot sleeve around his erection, the inside studded with hard little nodules and swirls. A separate chunk of pink slime closed around his head and began to nibble, chew, and squeeze at it like a disembodied blowjob, while another chunk of slime stuck to his testicles began to mercilessly knead and fondle his family jewels with just the right amount of pressure--not to hard as to be painful, not to soft as to be ignorable.
James gritted his teeth. It felt like the entire lower half of his body had dissolved into a hot wave of pleasure, and he unknowingly found tears leaking out of the corners of his eyes, completely overwhelmed by so many new sensations. As if to tease him a little more, the pink slime on his cock went berserk for a brief moment, fondling and fucking him so expertly that his knees gave out from under him. He threw his head back and screamed as he flopped onto his stomach again, completely prone. Despite his erection, his cock had been pinned down the other way, poking out from between his legs like a caveman's club.
Even so, the pink slime continued to work on him. The head of his cock transformed into a thick, purple, throbbing thing, but no matter how hard he 'bucked' it, he just could not come. Lucy tittered at this. Watching her slave boy so helpless to the pink slime was a pleasure in itself. Driven mad with stimulation, James began to rut his hips against the mattress in a lustful frenzy, trying in vain to bring himself over an edge that the pink slime simply would not allow him. The sentient goo covered his cock so completely that he couldn't feel anything beyond its tight, slick insides, but when he lowered his body to hump at the mattress again, a small aperture suddenly opened at the head just before he made contact with the bed.
The harsh friction of the bedsheet chafing against the tip of his cock sent up an incendiary burst of numb stimulation that he simply was not ready for. James howled. The pink slime closed over the head of his cock immediately, as if all of this had been done on purpose.
"Please!" James screamed. "I can't take this, Lucy. I can't! I can't!"
"That's what happens when you misbehave," Lucy said chidingly, placing a proprietorial hand over his left buttock. Although James stiffened at her touch, he didn't try to shrug away from her. They were making progress. The pink slime had a way with stubborn men like him. In her line of work, she had seen the pink slime permanently turn even the most battle-hardened soldiers into mewling, pathetic little fucktoys in literal minutes. On her planet, it was used as a form of torture for only the most heinous of crimes.
"Are you ready to be a good boy and let it do what it wants?" Lucy said.
"Yes! Yes!" James yelled. "I'll do--ggghh, fuck!--I'll do anything!"
"You're not going to fight it like a bad boy, are you?"
"No! No I won't. I promise!" he whined.
