"Hydra, yes, a beast so resilient that even armies would struggle to defeat such a thing." Everything then goes dark all around you as you feel a prick in your arm, and you hit the ground unconscious.
You woke up with thick chains around your arms, legs, and neck. They were just loose enough for you to lift your head up and get a look around the large spherical room around you. You could see all of the other prisoners gathered around you in similar chains, but not nearly as thick. All of the others also stood upright while you were bound to all fours, and just beyond the men were large passages branching off from the central room you were all inside.
That’s when the voice boomed through the room, and the chains on all of the other prisoners suddenly unlocked and fell to the ground. "Go now, run, run before the beast transforms and finds you! The hunt is no fun without a chase!" The voice boomed throughout the room, and you watched everyone flee around you.
Wait but what about your chains? That question was answered for you when you felt a sudden surge of lust through every vein in your body. "Ah! Argh!" You cried feeling your cock instantly become erect and blow its load out all over the ground. However your body didn’t seem satisfied, you wanted to grab your cock, stroke it, suck it, and jerk it off with all your might until you felt relief.
"Yes, that’s it, feel my power, my might, spill your seed for me, my pet," The voice said again, and you felt your balls churn and your shaft tense up as you involuntarily orgasmed again and pulled on your chains to reach your cock.
"M-Must..." You muttered not even noticing the large cobalt blue scales spreading across your arms and back,"...f-fuuck..!"
"Soon, soon, but for now look up and see your master," The voice came again, and you lurched your head up and saw a cloaked figure in front of you. By now your hair started falling out in clumps, your teeth growing sharper and fierce as your tongue grew forked. You struggled to hang on, but as your eyes turned into golden yellow slits your mind slipped away into a much more feral state.
At first you growled and snapped at the figure, but then it reached out to you and touched your head. When you felt the figure's hand it was as if you stood in front of a being far superior to you in every way. The figure ran his hand across the scales on your growing snout, and horns as they poked out of your skull. Your body started expanding in size, your muscles bulking up everywhere they could possible. In seconds you went from human sized, to horse sized, and then looking like you could swallow a man whole.
Your neck snapped and cracked, and your chains strained the growth of your muscles. Eventually the bindings around your ankles and wrists snapped and you let out a terrifying roar that filled the room and echoed off into the labyrinth beyond. Your head was now entirely whatever kind of creature you were, and your torso was heavily muscular and lined with thick scales that were stronger than steel.
You looked down at your hands and feet and saw that your legs had changed into digitigrade claws with 3 toes with large curved talons. Your hands matched your feet identically in ferocity in appearance and functionality and you stared down at them in awe. Your mind tried to cling on to what humanity still lingered, and that humanity seemed completely shocked before it was swallowed up by a subconscious instinct to hunt, kill, fuck, and obey your master.
Your cock was now a pillar in its size, 4 to 5 feet in length as your central body stretched over 12 feet long, your neck an extra 8 feet alone. You saw the veins in your mighty dick throbbing, and behind them you saw two testicles the size of beach balls then behind that was a reptilian pocket for your cock, a sheath to nestle your manhood when not needed. Then a building pressure in your spine gave birth to a new tail that grew out to a whopping 8 feet in length, and you felt a similar pressure growing from your shoulders.
"A-A-Raaaaagh!!!" You let out a beastly roar as the chain at the base of your neck snapped, and the collar fell to the base of your body. Then suddenly two additional heads sprouted out of your shoulders and grew out proud and large, both roaring loudly as they entered this world as your conjoined brothers. However that seemed to cause a chain reaction in your body as two additional pressure points built up in your sheath and gave birth to two additional reptilian phalluses, and all three of you couldn’t help but give out one last orgasm before all three of you looked down at your master.
"Good, magnificent," The Wizard said then suddenly you felt a frustrating strain between your legs, and your balls churned once more as you and your heads growled.
"You must all be in agony, three heads, three minds, three stomachs, and three cocks," The Wizard chuckled then added,"But one nervous system, one drive for lust, one ultimate desire to breed!"
All three of you let out another loud roar, and you started drooling, hungering to please your cravings for sex, to mount and dominate your foes, to shove them down on their stomachs and lick their ass and ballsack with your long forked tongue. You felt your other heads start salivating, each had the same thoughts as you but were different, each a part of your body but each lesser and unique, and each having a similar drive but different satisfactory desires.
"You’ll relieve yourselves as soon as you hunt the humans that dwell here in peril. You will find them, breed them, turn each and every one into one of your kind, and drive give them a large filling of your seed as they become like you. If you do well I might just reward the three of you with a treat," The wizard exclaimed and you and your brothers' eyes widened.
You lowered your head and grinned as you struggled to form words in your mouth, and what words you did form were of your feral desires to satisfy your body’s needs. "Rrrrr...rrrr....maaaaaaastrrrrrr... w-wherrrrre?!" You roared and your brothers both purr and pant as your tail wags and your cocks throb in unison.
"That’s your task, find them, show them your power, make them all yours. You are the alpha beast, and you make them obey, but you only obey me, now roar to show your compliance," The wizard commanded and you and your brothers let out the largest and loudest roar that you could muster. Your voices pierced the air and ears of all as it echoed throughout the caves, and the entire labyrinth shook violently around you.
Your master vanished after that, but you had your orders, so you lunged out towards one of the cave passages. Although speaking was all but impossible for you now you’re brothers' minds and thoughts spoke inside your own. "Track them by sweat, musk, and blood," one of them said.
"Fuck, make them suck, become, and worship our might," the other added
"So many mates, want to taste their musk, their cocks, their asses! If we do well we’ll get a reward! Let’s go brothers!" You exclaimed to your brothers and all three of you roared in unison as you plunged into the shadows as one sex frenzied beast. Eventually...
