Liam shook his head. "You'd think a kid from this town would know better."
Mike shrugged. "It's OK. Feels sort of weird, but good."
"Oh, it's about to get a lot weirder." Liam chuckled.
A shout from the kid and a tug on his penis made Mike twist around to look back. The boy was trying to pull his hands out from Mike's sheath, but they were stuck. Mike's cock emerged and revealed it had an iron grip on the poor boy.
With another tug Mike felt his cock take in even more of the boy's arms. When Mike's cock was fully erect, the lad was up to his shoulder into the cock, his head pressing right up against the gaping slit.
The boy felt the warm pre-cum hit his face and slide down his body. He still hadn't sop trying to free himself from the large black dick. Eventually, though the cock managed to drag in the boy head and his chest.
Mike on the other hand started to panic. His cock was being invaded by its own will and growing heftier with each intake of the poor kid. Mike thrashed around trying to shake the kid loose, but it was no use. His cock would not let go.
"Woah calm down," Liam said having held on to Mike's human back. " You could have thrown me off."
Mike looked at him. "I'm sorry. But you have to pull him out. I think my cock is eating him."
"Oh, it certainly is, and here's no way I'm going near that thing."
"But what'll happen if we don't get him out !?!"
"Well..."
Suddenly Mike twitched and moaned in pleasure. Liam hopped off and inspected what was going on underside the centaur. Liam's jaw dropped. The cock had the kid's body fully encased.
The cock gave one powerful twitch and mike's Centaur body spasmed taken with pleasure. The boy was shot right into Mike's
growing, accommodating testicles.
The centaur testicles fell to a few inches off the ground full of the kids’ weight.
Liam could only watch as the writhing figure struggled against its fleshy prison. Loud noises came from the centaur nuts as Liam realized the boy was being converted into Mike's sperm. Superior stallion cum frothed and churned in over grown balls.
Mike let out a gasp, and Liam knew it was over.
Liam walled up and pressed a hand onto the side of the balls, not a lump, or human shape anywhere.
"Well, that was something!" Liam said with fake enthusiasm trying to play the situation off. Mike breathing heavily could only look at him with disbelief.
Liam hopped back on Mike’s horseback "Come on we're almost there."
As Mike slowly trotted Liam rubbed Mike's human back and cooed in his ear, telling him " he did the best he could for the kid," and " how great a stallion he was.
Mike got the nerve to start walking at a normal pace and by then Liam was giving him a full, intimate, upper body massage. All the while Mike's balls sagged, full of his prime stallion sperm.
