There's no underage (under 18 years old) sexual relationship in my story.
*****
The young man Flavius resisted the two female centaur women who dragged him away forcibly, his arms and legs beating against their bodies. His chest was bare and fairly pretty, he'd been a fool and deceived by their claiming about a danger to their village.
He'd been returning home after war, and he couldn't ignored centaurs when they pleaded with him. He was a hero after all. With a tiny effort they took his axe; the horse halfed women were powerful and mighty like supernatural beings.
No longer strong and demanding, his voice became hoarse from steadfast yells and screams for help. Calls for anyone, any God or Deus, help, but there's no savior for him. His heart raced, sending blood and epinephrine forth though his exhausted body, pushing him into a total body convulsion.
They entered a centaur village deep within the woods. A great gathering of centaur men and women, as well as humans, watched his abduction with interest. He called out for them to help him but they looked to each other and laughed, or talked together with waving hands and eager nods. All of them seemed pleased. The fillies dragged him into a large wooden building near the east end of the village, and with little effort, they stripped him of his clothes.
His pants slipped off his legs while one woman held his arms and the other worked on the clothing. He said "Why are you doing this?" They didn't say anything to him, but talked with each other in the centaur language which seemed like Greek mixed with whinnies, neighs, and snorts. His focus on its nuances died when they tore off his under-wears.
Soon, he stood stark naked, trying in vain to cover up his body while the centaur women stood back and admired him and his naked beauty and his huge uncircumcised cock. He felt hot and cold in the same time. One of the female centaurs licked her lips and smirked. They weren't even the same species! The two centaur women, joined in by a third, began rubbing him down by a rough soap bar and the soap smelled of leather and wild herbs. They giggled as they ran their hands all over every inch of him, leaving nothing of him untouched.
Flavius's face prickled while they washed his huge beautiful uncut cock and boyish ass. He almost stopped resisting and struggling, so exhausted, and so afraid. "You are very lucky to be chosen," said the prettiest centaur women in thick English. "You are sexually pure, don't you, virgin?" . "Of course not. I'm very experienced." he lied. Then, without warning and for the first time in his life, a soft hand wrapped around his fore-skinned cock.
"Ohhhhh!" He squirmed away from the teasing. The women centaurs giggled again, smiling and nodding like they'd just learned their first jumping trick. "Oh yes!" said another woman centaur. "Very pure and virgin. This is our lucky day." Flavius tried to struggle again, but his muscles had became numb. A heaviness streamed through all over his body. His head turned to the side. The newest centaur held him upright as the others began to give him his first handjob and first gang handjob in his life.
"Stop!" Did he even speak? The word bounced around in his head. His leg twitched, his heart pounded violently against his cock. Soon, they lost interest in completing the handjob and they carried him to a bed of straw covered by a linen sheet and set his unresponsive body onto it. Without another care, the women returned to the washing area and began to clean up.
He could run, maybe dart out the door and hide under the building, crawl into some small place the centaurs couldn't get to. Or climb a tree? Maybe find some horses and ride one out of there? Everyone would see him, though, naked and trussed up like a sperm cow.
"We must go now. You can walk?" the pretty centaur asked, blinking her slanted eyes at him. With blossoming hatred, he glared at her. She smiled warmly, and the original two descended upon him, wrapped him up in a thin robe, and dragged him outside into the bright light of day.
A parade seemed to be in progress as a long, double line of centaurs in all colors and sizes: sorrel, chestnut, or bay, sprinkled with gray or white, appaloosas, huge Percheron, wearing various ornaments such as necklaces or headdresses, though most were as bare as the women centaurs who held him roughly. His escorts, one on either side, led him up onto a stage where he shifted on his bare feet.
The village of kidnappers all looked up at him. He had no idea why they'd taken him, no hope for an ally. The lines of the parade split; one went right and the other went left around his stage, circling him. At the rear of the progression a centaur woman trotted through the crowd, and the mass of humans and centaurs raised their voices in a welcoming cheer.
Her features were typical for a centaur, slightly elongated nose and chin, pointed ears. She had full, brown hair that trailed down her human back to the shoulders of her horse body. Her breasts were huge, gorgeous, firm and modest, and a circle of hedera rested on her head. Her almond shaped eyes were the most brilliant blue he'd ever seen. And they looked right at Flavius. She pawed the earth with her hoof and addressed the waiting crowd, who'd quieted with the simple lifting of her hand.
"Welcome, my people." She spoke in thick English. "I am pleased you have come out to witness the claiming of my chosen lover. As you know, it's been many years since the star-watchers had discovered ..." Flavius suddenly had a very bad feeling about this. The speech ended and the important woman centaur turned towards Flavius and casually walked over to him on the low stage.
"You are Flavius of Rome?"
Flavius felt himself nod. Happiness etched itself across her features; her blue eyes crinkled at the edges. "I have waited for you." . "Please, just let me go," he said, hopeful. She laughed, a deep noise that rumbled through both of her pretty boobs. "Oh no. Now that I've found you, I will never let you go." Flavius gulped. "But, you are free to roam the village and its outskirts." Flavius's heart sank. They'd taken his clothing and he had no idea where he was.
"What do you want with me?" The woman smiled again. Her lips were berry red. "Well, my lover, I will bear your child, the heir to the Centaur nation. Now my people will take you to your hut to rest."
After some days...
A knock on the wooden plank door of the hut woke him from a half-doze. "Mr Flavius. It is time for the refitting. The princess wishes to refit you herself." Flavius opened the door and saw the same centaur woman who'd chained him a few days ago. He followed the woman to another hut near the large building where he'd been taken, stripped and washed his first day here. She held the door opened for him, did a kind of curtsy with her forelegs, and waited.
Flavius tentatively stepped inside. The door closed behind him. Casting shallow shadows, a lamp burned warm within the small space, illuminating a waist high table and the horse-halfed centaur princess with blue eyes lying in some straw. When she saw him a smile blossomed on her face.
"My Flavius, you have come." She held her arms out as if Flavius would run across the room and throw himself into them. He didn't. Her face fell a little and she dropped her arms to her sides. "I am pleased you are here," she said in a more subdued voice.
"Princess," Flavius began, unable to keep the desperation from his voice, "I know that you seem to think I'm some fated mate that will reproduce with you, but you see, that really makes so little sense. Maybe, you should find a centaur to mate with, and just... let me go." Through his entreaty, the princess' face fell little by little.
"Please, call me Jessica," she began, her voice soft. She flicked her tail up along her rump and breathed a deep sigh. "Come closer. I promise, I will not nip." Flavius stepped closer, clutching his robes in his fists as a shield, the look of longing in Jessica's eyes.
"I've always been separate, waiting for the one the stars had chosen for me. That is you, Flavius. It is you, and only you, and the minute I saw you, you owned my heart and I fell deep in love with you, honey." she said.
Flavius shouted. "I'm man, and you are half mare and half woman with a mare's cunt and we're not even the same species! That's zoophilia or bestiality." Didn't she understand natural processes? But reality fed his panic, because Flavius understood a little of magic.
Then she laughed, a relieved exhalation. "Oh, is that your worry?" He stared at her. How could she treat this like a minor hurdle in the grand scheme of things? "You are my chosen one. And it has been done this way for centuries. I will not hurt you." She hefted up her weight and climbed to her four legs. "I would do anything to alleviate your fears."
