shadowess: I love this, but I think Harry is only pretending to be a 13yo girl to get what he really wants. *evil grin*
INSANELY DIRTY COMMENT PORN:
Harry straightened his skirts, then ran the curry comb through Severus' mane a few more times. "I love my Severus!" he declared as he ran the comb further down the strong pony body. Severus' coat was a grey so dark it was almost black, though he was lighter on his belly, and a smudge of white made his nose seem quite prominent. "He's the best pony ever," said Harry, his voice lower now, comb forgotten as he explored the pony's sizable undercarriage.
Harry had always been fond of his lover's size, satisfied with it, but when Snape had perfected his Animagus transformation and turned out to be literally hung like a horse, Harry had felt like a 13-year-old girl getting a pony for Christmas. Only this time the pony would, if the spells worked as they'd hoped, be having him.
Harry shifted his hips, his own prick jutting up from under the frilly little-girl skirts, while his hands coaxed Severus' huge cock from its sheath, then slicked every inch of it with the magical lubricant Severus had brewed for them, in human form. An impatient whinny reminded Harry that he wasn't the only one looking forward to this, and Harry sighed, letting go of his prize. "All right, Severus, I'm getting into position now," said Harry. He slipped under Severus completely, awkwardly bending over the padded bench they'd conjured for the exercise. His skirt was so short he didn't even need to flip it up, and he reached back to spread his cheeks wide, to give Severus a better chance of finding his goal.
Another whinny warned Harry that Severus was about to try, and Harry bit his lip and hoped the spell and everything else they'd done that day was enough to prepare him. He gasped when the tip of Severus' cock found its mark, moaning as it sank inside him with the same ease as always. "Oh, Severus, it's perfect," he mewled, letting go of his cheeks and gripping the bench instead. And it was, hotter even than Severus' cock usually was in him, bigger and more forceful as the powerful hips began to thrust forward, using Harry's willing body.
It didn't take long before Harry was thrusting back, prick shoved into the velvet cushions and his high, shaved balls battered by the rough-haired bollocks of his very favourite pony. Everything was perfect, from the rustle of his petticoats to the press of Severus' heavy body above him, the rub of the velvet and the inexorable pressure inside him. Harry cried out and came, soaking the cushion with his seed while the pony kept on thrusting, as deep as it could go into Harry's spell-protected body. "Please, Severus, please!" he begged, though neither of them was quite sure about what to do with the quantity of come a pony could produce.
Severus neatly solved the problem by turning back into a delightfully naked man, pausing only long enough to give Harry's body time to adjust to his smaller stature before giving the last few thrusts and coming deep into his lover's well-used arse. "You've never been tighter," said Severus wickedly, giving each upturned cheek a swat.
Harry grinned and stretched, clenching around Severus deliberately. "You've never felt bigger," he teased, though in a way it was true; even after the pony, the spell on him had easily restored his body to its usual tightness, and Severus felt huge inside his deliciously sore arse.
Severus laughed and swatted him again. "I overindulge you," he said fondly.
"I'm a very spoiled little girl," Harry agreed readily, twisting around for the one thing he couldn't get from his pony, a kiss.
