Chapter Text
It had been three weeks since the ceremony to purify the Nemeton, and thanks to the runes and spell's woven into his room to accelerate gestation periods, Stiles was ready to give birth. His belly was swollen huge with child and had forced him to remain bedridden as the weight pulled too much on his hips and lower back, and while Peter humoured the idea of letting it paralyse Stiles from the waist down he ultimately decided against it, he did like the fight in the boy after all.
On the day of the birth Stiles found himself returned to the room he had been bred in and strapped back into the breeding bench, this time though with his hips tilted lower, drawing a groan from him as it increased the pressure on his hips. A blindfold covered his face as he heard several footsteps enter the room, flinching as hands touched his lower back.
A sudden ripple of pain distracted him from anything the people might have been saying, so he didn't notice as runes were traced onto his skin to increase his body's healing and flexibility. All that mattered was a sudden feeling of something forcing its way out of his ass, his cervical plug and the following amniotic fluid splashed onto the floor beneath him.
"That would be your water's breaking right on time." Came the now familiar voice of Arcenio behind him, hands testing the looseness of his hole as his lower abdomen seemed to roll and tense with the sudden urge to push. "That's it Stiles, push."
Tears dampened the blindfold as he screamed in pain, the feeling of something a lot bigger than anything he'd ever taken suddenly beginning to move into his anal canal which stretched to accommodate thanks to the runes and spells already cast on him. Stiles felt his legs wobbling and was grateful of the fact he was strapped down as he allowed them to flop as the desire to push stopped, panting through the mild discomfort he found himself in.
It didn't last long as his body soon tensed again in pain, legs scrambling for grip beneath him as his body tensed and pushed before it abated again. He shuddered as he felt a hand rubbing against his belly, his body seeming to tense and push again with the touch and forcing a scream of agony from his lips when the thing shifted down a little more within him.
"He's too tense, this will take hours if we continue like this Mr Hale." Arcenio spoke from beside him, a second hand joined the first and felt along his extended belly.
"Hmm, you may be right, and while I do enjoy seeing him like this, I would prefer that this happened quickly, the faster to get him ready for his next customer. Arcenio, open the door and let our returning guest in to reunite with the mother of his child." Peter' voice seemed to smirk before Stiles heard both sets of feet move away from him and the slide of a door open.
Another ripple of pain took his mind away from anything else, body straining to push out a child it was never designed to hold. As he lay panting for breath when it passed he became aware of a shadow looming over him, a small whimper of fear passed his lips as hot breath whiffed against his ear and something sniffed at his growing hair. He thought it might have been the stag from that night but blinded he couldn't be sure and was left wondering as the hot breath left and he felt the frame around him rattle with the weight of something heavy.
His mind soon went blank as something hot and dripping pressed against his lips, mouth dropping open eagerly for the cock that began to piston in and out quickly, heavy balls hitting his chin with every thrust. The next wave of contractions he barely noticed other than the feeling of his hips jerking in time to the waves, and it wasn't long that as the stag above him roared and came down his throat, Stile gave a gurgling scream of his own as he too came. The thing inside him shifting further down as his body jerked and spasmed around it, Stiles' eyes rolling back in his head as it began to press on his prostate.
Lost to the feeling of mixed pain and pleasure he was only aware of the stag moving off of him as he was suddenly able to babble pleas for more, hips shifting as much as they could as his contractions continued along with his orgasm, forcing what was inside him further and further, his hole beginning to open wider as long legs began to breach, a groan announcing the arrival of the faun's head as it pressed hard on Stiles' prostate and stretched his hole wider.
His mind stretched thin by the never ending pleasure it wasn't long until he was merely a drooling wreck, paper body slumping in the stand as his hips continued to jerk and spasm, working the rest of the faun out until with a gush of more liquid and some blood it slipped fully free. Arcenio was immediately there to tear the amniotic sac since Stiles wouldn't be able to and used a towel to clean off the fluid from the faun.
Unlike its sire the faun wasn't pure white, it bore soft brown freckles across its back and hind legs, and as Arcenio stepped back to let the stag himself finish cleaning the faun and urge it gently to its feet he could see it had the same shade colour eyes as Stiles, an intelligence behind them that seemed more than just supernatural. He didn't think much of it as he began to clean up the floor and wait for Stiles to finish passing the placenta, taking it away with the towels to examine and ensure everything was healthy with it.
Peter and Denton watched as the faun quickly got control of its feet, starting to prance around the room before moving to nuzzle Stiles's non-responsive form. A snort from the huge stag drew it away and the two men watched as it reluctantly followed after its father and left the room.
They smirked to each other as they stepped closer to the body laying lax on the bench, runes sparking across his hips as his body began to heal anything that had been damaged by the birth. "I must say I expected it to be a lot bloodier than that, after all, no male human body is designed to have something that big forced through without some kind of prep, even if it is magically altered somewhat." Peter confessed softly as he gazed into the aping hole before him.
Denton chuckled, kneeling to inspect the gape as well, fingers brushing against the stretched rim in fascination, clearly able to see deep inside the boy, even able to make out the gaping hole further in that must be the boys cervix. "The boy is a spark remember Peter, so whatever suggestions you convince his mind of, the results are limitless, imagine him breeding with a cyclops, nothing but a living cock sleeve." the vet groaned, palming his pants as the image came to mind.
Peter chuckled, "I might be convinced to let you record that breeding session, Arges is much looking forward to it when his time comes. His brother too," he chuckled, drawing Denton to his feet and leaving the room, knowing Arcenio would look after Stiles and return him to his room.

Peter had been pleased with the results of the afterbirth tests and how quickly Stiles recovered, so after a week of monitoring he was ready to start the program properly with Stiles, sending out the first confirmation letter to call upon Stiles' first paying customer.
