It all started happening so fast, Andre didn't know what was going on. One minute he was walking out of his friends' bedroom, about to head to the bathroom, next thing he knew a yellow pegasus pony was giving him orders. Now, normally, he wouldn't listen to strange hallucinations, but hey, gotta live a little, right? What's the worst that would happen?
A lot of things, apparently. As he got on his hands and knees with his eyes closed, suddenly a foreign object got shoved into his mouth. It was so hard and long that he found himself choking on it, but he couldn't get a sound out. He couldn't even move, as the strong pony kept his hoof on his back.
"Hey, just make this easier on the both of us, okay? It's my duty to the princess, so this is happening whether you want it or not. However, I'll do my best to make it enjoyable for you." the stallion who you know as Thunder Flash says.
Before Andre even (attempted) to beg through his stuffed mouth, he sees Thunder start to thrust into his mouth.
'Oh god, is he going to...?' Andre thought. 'I'm...gonna be sick...'
He really truly tried to break free once more, giving it his best college try, but the pegasus was too strong for him, despite their size difference. Soon, he felt a hot liquid shoot down his throat, making him want to gag, but he could already barely breathe. Reluctantly, he opted to swallow now and vomit later.
But, the moment he did that, his whole body started to tingle. It was a feeling unlike anything he'd ever experienced. Slowly, he noticed that the railign next to him was getting taller, and he noticed himself shrinking to Thunder's size, if a bit smaller. His whole skeletal structure started to morph into that of something fit to walk on all fours. It should have hurt. No way something like that wouldn't have, but for some reason, it didn't. Did it have to do with Thunder's...no, can't be.
Thunder looked at Andre, still holding him down, but taking his member out. "I told you I'd make it enjoyable. Just relax, and let it finish."
"W-what...urk...is happening to me...?" Andre gasped, dry-heaving. He saw his hands forced into fists and his fingers starting to melt together into one stubby appendage. "No...no....you're turning me into a pony??"
"Not just any pony. Aqua Heart," Thunder smiled, glancing at the light blue fur starting to spread over Andre's body, his legs and feet having changed as well.
"A-aqua Heart? But...Aqua Heart is a mare!" Andre gasped, his voice turning very...feminine...during the last word. He gulped, realizing what truly was going on as a cyan strand of hair flowed down over his face, a matching tail flowing out from above his butt, or rather flanks, now. He wrenched his eyes shut as they grew larger, feminine eyelashes growing from the sides of them. With a pop, his face stretched out into a mare's muzzle, as his ears moved to the top of his head and became pointed.
Two nubs sprouted from his back, growing into skeletal wings before the skin and feathers grew. And lastly, the part of this he did not want, started to occur. His body become more curved in places, and his figure slimmer. Not skinny, but fit, like an athlete. He then felt his male bits start to retract into him, and winced as shifting started to occur inside. And on the outside, two mounds grew.
She exhaled and looked up at Thunder as he released his hoof from holding her down. "I...um..." she didn't know what to say. How does someone react to being turned into a female horse except for sheer shock and speechlessness?
Thunder grinned and reached into his saddlebags with a wing. He pulled out a necklace. One made of silver with a bright blue sapphire in the center. The same one Andre gave to Julie, made to look like Aqua Heart's necklace from the show. While Andre laid there, still unsure what to say, and a bit exhausted to fight back, Thunder put the necklace around her neck.
Suddenly, her eyes widened and everything became clear to her. She was Aqua Heart, a confident and playful pegasus mare. Working as a lifeguard at Coral Bay. She was married to Thunder Flash, who she loved with all her heart.
With a smile, she got up and leaned in for a deep kiss. "I missed you, dear."
"You too, Aqua. Mind helping me with something, though?" Thunder asked.
"Anything, my love. What is it? If you mean what I think you mean, I'm down for some horizontal tango," she winked. "Or is it royal duties again?"
"Well..." he started.
