From Butterfly to Tadpole
Fluttershy blushed. She had always suspected that Rainbow Dash was a mare chaser, but she had never guessed that she actually had a crush on her.
"Um… Rainbow Dash, I…" Fluttershy began before being interrupted.
"It's ok if you don't feel the same, Fluttershy. I know this is kinda sudden." Rainbow Dash said, blushing.
"No, it's not that… It's just. Why me?" Fluttershy asked.
"Because I envy your strength." Rainbow Dash replied. "I'm really shy and insecure. I just act all tough because I'm really…"
Rainbow Dash trailed off and blushed. A tear welted up in her eye. Fluttershy whipped the tear away with her hoof and gently kissed Rainbow Dash on her lips. They looked in each other's eyes and then smiled.
"Oh Fluttershy…" Rainbow Dash said cooed, "If only I was strong like you."
They locked lips and began to kiss passionately. Their tongues battled for supremacy. Fluttershy's heart was all a flutter. Not only was this her first kiss, but it was with a mare! What was more she was starting to enjoy it!
Eventually Rainbow Dash forced Fluttershy onto her back. Fluttershy felt weak as Rainbow Dash's tongue probed deeper into her mouth. Something wasn't right, though. Rainbow Dash's tongue was beginning to force its way into her esophagus. The yellow pony should have been feeling scared but for some reason she was in ecstasy. She had no idea that blue pony's saliva had a powerful narcotic in it.
The tongue probed deeper and deeper, finally reaching her stomach. Once there it's tip opened up and began pumping eggs into her belly. Rainbow Dash's narcotic saliva was powerful but not so powerful to prevent Fluttershy from becoming scared. She could feel them moving around in side of her and she was starting to panic.
She wanted to scream or fight back but she couldn't, she had no strength. Rainbow Dash's eyes glowed green and had a nefarious look about them. They were not the gentle eyes that she knew.
Her stomach began to bulge and stretch as the eggs filled her up past her stomach's capacity. She should have felt pain but instead she felt intense pleasure. The sensation was indescribable. She was at her limit and finally her body quaked with a powerful orgasm.
Finally Rainbow Dash pulled away, her elongated tongue slipping back into her mouth as she smirked. Her fur slowly turned black and oily. It wasn't Rainbow Dash at all, it was a changeling!
"Take good care of them now,' the changeling said in a reverberating and high pitched voice, "Those are our future, you know."
The Changeling flew out of the window and left the yellow pony there on the floor of her room in a puddle of her own lust and shame. As she lay there tears streamed from her eyes. She could feel her insides churning but the worst part was that for some reason even though it hurt it felt good.
Eventually she heard screams coming from outside. Someone else was in trouble! The changeling had probably taken another victim. She had to warn others. She had to get help. Even as she lay there in agony the selfless pony was thinking of others
Even though her body was distended to nearly 3 times it's normal girth she crawled her way outside to look for help. When she got outside what she saw nearly fractured her mind. Every mare in Ponyville was in the streets wrenching in both agony and ecstasy as beads of what looked like frog eggs poured from both their mouths and rectums. Countless little changelings erupted from the eggs that had only recently been laid. They scurried around making horrible chirping sounds and nibbled on the varius mares scattered about. Fluttershy began to panic.
"No, no, no, no...;" She said to herself and she covered her eyes.
Suddenly she felt her insides begin to rumble. She could feel something beginning to work its way up her throat. Her mouth opened all on its own and a stream of what appeared to be large frog eggs began to pour from her mouth. Next she could feel something crawling its way through her lower stomach and soon more eggs began to pour from her ass as well. The sensation was too much for her to bear and eventually she passed out.
She lay there on her side as eggs continued pouring from her body. Her eyes were open but they stared blankly past the world as her mind had turned itself off to try to protect itself. Eventually the flow of eggs subsided and she lay there, her flabby, stretched out skin hanging in a puddle around her body. It wasn't long before all of the little creatures hatched and began to crawl to their mother. They nestled up to her and began to crawl about her.
"Mother, we're hungry…" they all said in unison, evil grins upon their toothy little faces.
She was still unconscious as they began to nibble on her skin…
