It's Rainbow Dash's birthday, hurray! A mystery gift from Princess Twilight Sparkle, hurray! A sudden and unexpected transformation leaving Rainbow Dash packing a throbbing member inside of her pants, hurra--huh?
That's the situation as Canterlot High's top athlete grows a new attachment right there at her birthday party sleepover. Thankfully no circle of friends is more supportive, and none other than Pinkie Pie drags her off to the closet to take the new part for a spin. What secrets does Rainbow Dash's new attachment hold? Is it possible for something to be so tasty that it's addictive, or is there some sort of magic at play here?
Note: The chapters of this story are episodic in nature. You can easily pick and choose which ones you'd like to read based on the pairings and not really be lost in the story. Basically, everything that happens is because Rainbow Dash has a magical cock amulet...and that's all you have to know! I encourage you to check out either the whole story or merely the chapters that appeal to you. (I've included character tags beside every chapter.)
An ongoing story commissioned by RoastPelican. Thanks!
