You sit in silent terror at what has become of your body. You want to scream, panic, or at the very least touch the grotesque cluster of manhoods attached to your groin to verify they're truly yours, now. However, your body is still thoroughly numbed by whatever your cowtaur captor used on you from the operation. You can barely move your eyes, much less your limbs.
"I can only wonder what's buzzing around in that little skull of yours, my little milk-man. Is it pride? Fear? Oh, the fun we'll have once you're back in working order." To accentuate her words, she daintily taps each of your three horse cocks as they remain contained within their sleeve, causing you to feel a distant thump through your sleeping nerves with each strike. "My mind is already alive with the possibilities! Do I try three different experiments, one for each? Or do I make you my big producer, so I can practice on fresher subjects?"
Bessie paused from tormenting you, looking down one of the blackened paths leaving this room. "Oh my. More invaders in my labyrinth." She turns back to you. "Maybe you'll have some little companions at your stall. Or, maybe you'll have some more donors to help your productivity." She regards your current condition. "This shouldn't take long. Don't go anywhere!" She gave a playful caress of the engorged bull testicles laying between your legs, causing them to pulsate and shift in response.
Now was your moment. Bessie would surely keep growing your balls until you truly were a permanent fixture to her farm. You frantically struggled to get some sort of response from your body. You try raising an arm, clenching a hand, twitching a finger. But alas, all you could do was blink.
Adrenaline rushing, you continue to press for some kind of activity from your body, until finally, you managed to move your mouth. What started as a twitch slowly progressed into being able to open and close your jaw. With that, control slowly started to creep back through your body. After your jaw, you started to turn your head. Some time after, your arms began to flop about at your command. Finally, you started to move your legs. Unfortunately, you could barely feel anything throughout your body, apart from the distinct existence of your various limbs and sets of genitals. Still, you didn't have time to fully recover!
You clumsily half-kick the gargantuan set of bull testicles between your legs until they're hanging off the side of the bed. You lean to stand up, then immediately topple forward. This causes you to bodily crush your three sets of centaur genitals, causing one to be caught directly beneath you while the other two splayed off to your sides. Unlike the other actions you'd taken so far, this seemingly fully awoke your body as you involuntarily vomit some of Bessie's milk from the pain.
You scramble off your newly-acquired testicles, massaging them so you can mitigate some of the pain. You keep yourself hunched so you don't topple over a second time. With a careful lurch forward, you're surprised to feel comparatively little from your bull testicles as they drag along the floor. The engorged scrotum may still be numb, or perhaps the skin had grown thicker with it.
You'd have to count your blessings later. You need to escape now.
Dragging your body down one hall after the next, you realize that you truly have no idea which direction you should go. As you wander from one tunnel to the next, passing through the odd room rarely, you start to reflect on your predicament. What would happen if Bessie caught you? She clearly had some sort of knowledge of the labyrinth's inhabitants, or maybe she was just paranoid? What would you do if you escaped? Your plumbing is a nightmare. Could it even be surgically removed? What if you found some other denizen, and they wanted to do something even worse than Bessie? How long did it take for you to start escaping, and how long had you been moving?
That last question became increasingly important as the numbness continued to subside. As much as you hated to say it, your bull testicles were starting to produce, based on how pent up they felt. Worse yet, the centaur cocks were rubbing one another, and they were causing you to inadvertently pop a boner or three. What you hadn't expected was how much growing they'd do when erect, or how much they'd leak once "ready." You were disgusted by their alien appearance, but the bouncing provocation of your movement kept them hard.
As you rounded yet another corner, you quickly realized you'd found something...
