A Nightmare of a Foal (Private with Jacob kojitsu Midnight)
 

Nightmare Moon smiled, as her body finally reformed. For quite a while she had been craving a child, someone she could mold into the perfect foal, and to appease her motherly nature. She had been looking into the house of a young boy named Jacob, on a planet known as Earth. He was reading a book. Chuckiling, she readied the nursery within the remains of her former castle, hoping that mistake Nyx would never come here. She formed a portal, ready to suck him in.

(Can Jacob be a Brony?)

(i suppose he could.)
Jacob was in his room, reading a book on gaming. he was your standard nineteen year old, content to laze around the house until he found something to do.

"Perfect." Nightmare chuckled, as a vortex appeared behind Jacob, and pulled him into Equestria. She towered over him, smiling, "Welcome to Equestria, Jacob."

Jacob let out a cry of shock when the portal pulled him in. when he saw the pony towering over him, he froze. "e..equestria? this..this can't be real.." he muttered in slight fear.

"Oh, it is Jacob." Nightmare smiled, levitating him into her back. "And e reason I have brought you here is because I have been wanting a child to take care of, and you were the most likely candidate." She brought him into the nursery.

(Hey, I was reading an RP between you and Zilla where a similar thing takes place, except with Twilight. Sould Jacob be forced to like being treated like a foal, or on his own? Because I would want him to like it on his own.)

(sure he can grow to like it.)
"b-but..why me?" Jacob asked, a tremor to his voice.

"Because you enjoy the show that has taken inspiration from us. We have contacted the writers and cast to get it down perfectly." Nightmare smiled, removing his clothes and powdering and diapering Jacob. "Now, you look adorable." Se nuzzled Jacob, dressing him in a dark blue footed sleeper with stars on it, and attaching a pacifier to his neck around a cord. "Would you like to play a game or watch Tv?" She asked, pointing to some game consoles, foal toys, and a TV.

Jacob blushed as he was diapered and dressed in the baby clothes. he knew he couldn't resist because frankly, she was massive compared to him. "Tv?" he half-asked, not sure what shows or games they had in equestria.

"Of course. Oddly enoughly, it seems most of the video games Luna acquired over the years we were fused together are pony, or really any of the species on Equis, versions as the ones on Earth." Nightmare smiled, nuzziling her foal, "Go on dear." Se smiled, gesturing with a wing.

tenatively, he began to walk towards the tv, though he noticed the padding was making walking difficult. after five steps or so, he wobbled before falling on his padded rear with an eep.
