He didn't care for Guaco, not even as the tapir's body trembled around his tentacle, taking pleasure from it too. For he could not help but feel good as his prostate was teased, the push and thrust of the tentacle rammed up there caressing it with every stroke. It was so thick that Guaco could hardly think straight, though his mind was not with him, not as he moaned out in confusion, something thick in his mouth, wriggling down his throat. He felt as if he needed to breathe too but, somehow, that was taken care of for him, leaving him aching, his cock hard, so very hard, throbbing for release.
That release was to come too as Guaco thrust and trembled, laid out across the very counter that he did his business on. if he had been able to understand what was happening to him, that would have been an especially humiliating moment for him and yet all he could do was moan and whimper and slurp helplessly on the tentacle. His backside ached and yet it was a good kind of ache, the kind of ache that made his gut throb, wanting more, always more.
"Good..." The mind flayer murmured, eyes alight with dark greed. "I might even return to you... Though this will feel solely like a dream to you. Or perhaps a nightmare. You are a willing one..."
Still, it being against Guaco's will overruled any willingness for pleasure that was at play there, regardless of what the mind flayer considered it to be. The shape of the tentacle pounding Guaco's arse showed through his lower abdomen as if it was trying to push all the way through, though his body remained soft and flexible around it, despite the natural contractions of his muscles. He squeezed on the tentacle, stars leaping and dancing behind his lowered eyelids, unable to hold back (why would he be doing that anyway?) as his cock spurted, drooling and dripping cum over his own stomach.
Up and down... His body rotated. Somehow, he was up in the air, the mind flayer holding him there, though it was not the strength of the tentacles crawling over him that kept him aloft. No, it was magic, not the kind of magic that he brewed in his shop but something far more carnal, something darker. As evil as it was, it came with a sparkle of excitement too, the lure of power too great for many creatures. And it was that magic that ploughed brutally up into his tail hole as he was fucked, again and again, stretched open by a second tentacle.
Guaco's head rolled from one side to the other, no longer even able to hold it up, chest heaving, even his jaw falling slack. All he knew was pleasure, how it blistered through him, though there was still a part of his mind that scrabbled and clawed, begging and pleading with the horror that was his reality. The mind flayer dealt with that, however, with a sweeping pound of both tentacles at once as something stealthily rumbled deep in the pit of the monster's being.
"Raaaaarrrrrggggghhhhhh!"
It was coming, whether Guaco was ready or not, the mind flayer filling him with his cum, though it spilt quickly into him, pump after pump, as if he was being filled from a cask. But his belly had to make room for it, bloating out and out, first as if he was a little on the plumper side and then swiftly in the lure of erotic inflation, bulging smoothly to take every drop of cum that the mind flayer's tentacles had to give. More and more flowed forth, the smooth rise of his stomach holding it all, forced up his backdoor entrance, even as Guaco squeaked and squealed on the penetrating force of two tentacles at once.
"Ah... Yes..."
The mind flayer trembled, softening a little after climax, though there was still one more thing to go, the tapir's belly bloated out as if it was a child's toy ball -- something oversized and large, bigger than any natural pregnancy would have been. Yet it was the male who would be forced to carry a pregnancy of sorts too as the tentacles bulged, moving the next course into action.
Eggs. One after the other, they brought the final debasement to the tapir's humiliation as bulge after bulge forced their way up into his backside, straining his tight tail hole around them. Hazy with pleasure and strain, the tapir shook as he moaned, head hanging, on his side on the counter where his belly could rest, the tentacle that had been in his mouth now wrapped around his snout. He didn't have the energy to cry out for help anyway.
So it was that the eggs were forced up inside his tail hole, landing in his belly as that smooth round became lumpy, bulging where the eggs were cushioned with the mind flayer's seed. The tapir whimpered mutely, yet his cries were ignored as he was fucked and bred, his belly rising even more to take in the massive volume of eggs.
There was no escaping and it was a pregnancy that the male would hold until it came time to lay the eggs, though no one would know what could be done then. Few survived an encounter with a mind flayer or returned to their normal lives afterwards, but the particular mind flayer that he'd encountered had a plan.
The tapir moaned, belly aching, his cock hard all over again, helpless under so much stimulation. All against his will...and yet he would bear the marks and the belly of his taking for months to come for all to see. With cum leaking over his stomach, he moaned, slipping, finally, into sweet unconsciousness.
The mind flayer had gotten all he needed.
