well...you always did want riding lessons

You couldn't escape even if you tried, with his strong hands gripping your legs and your hands already chained above his body you're about as helpless as can be and completely at his mercy. "W-wait....please can't we ta-" you go to say but your words fall silent and your eyes widen as he suddenly begins to impale you on his fleshy log of a cock. All you can do is let out a silent scream as inch after inch of the equian length sinks deeper and deeper into you. It feels as if its about to split you right down the middle, each pulsing vein along its meaty shaft can be felt rubbing against your inner walls as it continues to **** its girth deeper and deeper into you.

"GHHH!...W....Wai...wait!!" You cry out, slobber flying from your mouth as a large and visible buldge begins to **** itself out of your mid section. The centaur all but completely ignores you as his powerful arms eventually leave you half impailed on his length. "Do not worry, we will breed many times in the near future so you will have a chance to get used to its size." He says rather nonchalantly, almost as if you weren't currently impaled on his meat underneath him.

You try to speak, to cry out, to do....something! But its almost as if his cock has speared you right through the brain, interupting all of your thoughts and replacing them with nothing but the image and sensation of its size violating your womanhood. This is only magnified by a factor of ten or so as he begins to move, his massive hooves thumping against the dirt as he turns and starts on the journey back to presumably his home. Every little movement from the slightest jostle to a large gallop sends shockwaves of pleasure roaring up your spine and directly to your nervous system as this hulking beast of a man begins to pick up the pace.

"Ngh....nice and tight, you're already proving yourself as a natural heifer!" He exclaims as the wind starts to rush past you both, you don't understand a word of it though. Your body is currently swinging back and forth against his length rapidly, sending the massive member in and out of your gaped insides again and again as it continues to destroy not only your pussy but your mind as well. Your tongue hangs loosely out of your mouth and after the first few miles the only noises that escape from you are a series of incomprehensible moans, babbles and cries as you're easily **** to orgasm after orgasm.

After about your fourth or fifth explosive climax something suddenly begins to happen, without any warning signs or even a word from your equine captor his cock begins to twitch and spasm, each vein pulsing rapidly as they bulge out against your walls. Moments later the final nail into the coffin that is your current mental health comes in the form of a tsunami of warm, thick seed. It knocks the breath right out of you and all you can do is stare blankly at the ground with your mouth agape as you're almost certainly fertilized with shot after shot of this powerful beasts semen. The powerful beast in question though barely even reacts, the only evidence that he's currently pumping you full of his seed is the salty trail dripping behind you as the excess cum practically flows out of your broken body.

Even though in your cross eyed, dumb fucked, sexually destroyed and cum stuffed state you wouldn't possibly be able to tell you've actually arrived at what appears to be the beasts domain. A large cave stands in front of you and your captor seems rather content as he slowly trots in the entrance with his busty slut of a prize still hanging underneath him
