Dayson couldn’t have stopped himself if he wanted to. Whatever Study Break had done to him had filled his mind with the need to take this gorgeous mare. Some part of him thought of it as a rut, but he didn’t care. Instead, he stood as Study Break looked over her shoulder at him. With a twitch of her fingers, she sent an invisible wind to wrap around his cock.

Dayson groaned as he felt himself grow. He glanced down and blinked as he watched his manhood thicken and lengthen slightly.

His clothing shifted… and then fell off.

For a moment, he found himself entranced by the sight of his own dick and heavy balls. He looked at his… his… stallionhood and stroked it once.

Study let out a single needy whimper.

He knew she had done something to him. He didn’t care. Only one thing mattered: he needed to fuck this mare. Right now. There wasn’t anything in the world more important.

He wasted no time in lining himself up. If the need to… to… breed this mare hadn’t been so strong, he might have teased her a little. Some part of him thought about it… for half a second. Then he slammed himself into her all the way to the hilt.

Study Break’s back arched and her tail wrapped around his chest as she let out a cry of desperate passion. She shouted his name as her whole body convulsed. Like he had when she had wrapped her hot muzzle around his stallionhood, she came the moment he thrust into her. She squeezed him tight, her experienced pussy sending shivers through his body, up his spine and into his…

For a split second, he was confused, knowing something else should have happened. But then Study Break bucked desperately and he thrust again. She let out another cry as she came around him, jiggling and shivering like a mare in heat. The scent of her drove him wild, filling his nostrils and his mind with images of fucking pony people.

He leaned down and grabbed her hips instinctively, slamming her thick rear into his crotch.

“Oh… oh Day…” Study moaned. “Oh, you feel incredible!”

Dayson knew she had called him something strange, but it didn’t matter. All that mattered was the need to pound this mare. All the mattered was he needed sex. He needed to mate. She couldn’t conceive, of course. But fucking was still mating. And he needed it. She needed it. He needed to make this mare cum until his cum erupted into her and filled her to the brim.

So, that’s exactly what he did. With every thrust, she gasped, groaned and moaned. She braced herself on the chair, making sure he had full access to her pussy and hips, though when he tried to grab for her tits, she playfully batted his hands away. He… he couldn’t bring himself to try again. Those were the final lesson. He knew it.

“Celestia above…” Study moaned. “I… I’m… I’m going to… again…”

He rode her through her third orgasm and that’s when she looked over her shoulder, her mane a mess, her breathing heavy and her eyes desperate.

“Cum in me, Day,” she begged.

The voice seemed to reach down inside of him, bypassing his brain entirely. With renewed ferocity, he pounded her wonderfully warm and wet pussy. No matter how wet it became, she gripped him hard.

“Pull… pull my… my tail…” Study whimpered. “One more… do it… do it when you…”

Then her panting drove out any words, but Dayson knew what he had to do. He had to make her cum one more time.

His stallionhood stiffened inside of her. His balls began to churn. He thrust himself as deep as he could and yanked her tail hard.

She screamed so loud it left his ears ringing. Her supple and voluptuous body went into convulsions around his enormous stallionhood as he began to erupt into her depths.

“Dayyyyy…!” she howled as she thrashed and bucked. But he didn’t stop. His hips moved of their own accord. He held her hips and sprayed his cum into her hungry pussy, feeling her inner walls massage him, clamp down on him and milk him as if he were nothing more than a breeding stud.

Finally, Study let out a long, low gasp and collapsed atop the chair. The shift in her position managed to make his slightly softened member slip out of her.

That’s when he realized he had just fucked a horny ponygirl with… with… a stallion’s cock. Because there was no way what hung between his legs was human. He collapsed back into his chair, staring between her sopping wet pussy and his enormous cock.

But… hadn’t he always had one?

No, of course not. That was… silly?

“What… what just…?” He tried to ask a question, but the thoughts were murky and slow. He gently brushed his right hand against his stallionhood as the band shone with pink light. He stared at it and finally understood.

He hadn’t had one ever before, of course. This was all his magic. Like the pony person virus was all him. He was responsible for it all. So much delightful…

Somepony giggled.

Dayson shivered as something in his mind yanked back. He felt his mind rearrange itself and had the oddest sense of deja vu. Then it the truth came back to him.

He had been transforming everyone around him into ponies. Now… it was his turn. And if what lay between his legs was any sign, mares would be falling over themselves to get a taste of him.

He giggled as he realized his days of fantasizing about girls was over. Now, his days of actually fucking them started.

The light from the band burned even brighter as movement caught his attention. A very naked, sweaty and lusty Study Break had managed to get herself back to her feet.

“Well…” she said, her tone husky and heated. “You… you definitely… passed that test.” Her eyes rolled slightly and her tongue lolled. “But now it’s time for the final lesson.”

Despite everything, he felt himself stir again as she stalked toward him, hunger glinting in her eyes.
