Dommy-Momcubus (Private wit AJbestpony)

Lillian was finally going to do it. Sure, it had been almost three years ago, but she was still mad. Her old boyfriend, who she once loved dearly, Gabriel, had stood her up at prom, just because he found out she was incontinent, and didn't want to pursue the relationship further. She sprinkled the last bits of talcum powder, forming a pentagram, surrounded by the letters of the english alphabet, with squares around them. She placed in the center of each point, a lavender-scented candle, and a blanket that she had as a baby was balled up, and put in the direct center of the pentagram.
"I'ah, I'ah, Domina Momcubyss!" She shouted, throwing her arms into the air, and preforming the semantic portion of the ritual, "I summon thy! In exchange for a new recipe for nutritious baby puree, to punish one who hath wronged me!"

As soon as she uttered that incantation, the lights in the room dimmed, and a strange smoke began to emanate from the ground. It was followed by a flash of light, and when the light faded, Lillian was no longer alone in the room.
Before her stood a tall woman with an hourglass figure, shapely hips, and almost ridiculously large bosom. She was clad in a black corset which left much of her rack exposed, along with matching gloves and stockings. Around her waist she wore a belt. "You have summoned me, dear one?" she said in a rather motherly tone.

"Yes!" She exclaimed, before taking in a deep breath, "Alright, so, I followed everything in the book right, and I have some requests to make. I heard you take things that aid in your job, so I thought you'd appreciate this."
What she handed to her, was an old recipe, written on parchment, for a mix that created a paste for the infants of ancient nobility to eat. It called for prunes, for laxative effects, and juniper berries, to act as a diuretic.
"Now, would you like to hear my requests?"

The Momcubus looked the recipe over, and she found it quite appealing. "This is sufficient to meet the requirements for my services."
As she folded the recipe and put it away, she asked, "Now, what would you have of me, young one?"

"So, there's this guy, Gabriel Walden, and he's was a big baby to me, at one point in our lives," She said, as she took out an old, dusty baby-blanket, "Is this enough to find him? If so, I want you to give him the most you've got. Utterly humiliate him, and never, ever tell him why. I want you to take photos, and make scrapbooks out of them, for each stage of babying you humiliate him through. Un-potty train him into diapers, and then intentionally poorly re-train him. The rest is up to you. Do it for however long you want, but I'd like enough for at least three scrapbooks, the scrapbooks being my final payment. Any questions?"

Momcubus was impressed with how much detail Lillian had taken into account. "He must have truly wronged you," she observed as she took every aspect of her plan to get back at her ex into account. "I have no questions at present; everything appears to be in order. Is there anything more I must know?"

"He's very feminine looking, and insecure about his masculinity, can't grow any hair for the life of him... use it." She said, "Now, he's alone, vacationing out in a cabin on the mountains. Nobody is going to look for him, for at least a few months. Strike at him there, got it?"

Hundreds of Miles Away:

Gabriel Walden returned to his cabin, glad to be out of the cold and snow of the mountaintops. This property had been in his family for years, and was insulated well, as well as virtually indestructible. He sighed, as he took of his clothes, put on his nightclothes, and got into his bed, dozing off, not knowing what was in store...

Momcubus waited until her prey had fallen asleep, and then she swept in. Moving carefully and gracefully so as not to disturb him, she pulled back his covers and began to undress Gabriel. Just as Lillian had claimed, he was rather feminine in appearance. He did not have much in the way of muscle, and if not for the lack of breasts, his physique could have easily been mistaken for a woman's.

"Better get to work," Momcubus thought to herself. She started by taking out a large diaper. A very thick, soft, and pink diaper. She carefully wrapped it up tightly around Gabriel's loins, patting the front when she was done.

Next came the restraints. She got out a straitjacket and forced his arms into it, cinching it up tightly at the back so that he had absolutely no room to wiggle free.

Finally came the gag. She took a pacifier, forced it into his mouth, and fastened it on the back of his neck with a strap. Now Gabriel was diapered and totally helpless before her. All she had to do now was wait for hi to wake up.

As the overcast sky lit up that morning, he began to stir. He felt the garment on his groin, and tried to reach to see what it was, only to be caught by the straightjacket. He attempted to yell out, but it was muffled by the pacifier. He was helpless.

(I'm not the biggest fan of straightjackets, if that's OK? Sorry)

[AJbestpony]

(That's quite alright. We won't stay in it for very long; just long enough for Momcubus to assert her dominance over him.)

"It would seem the baby girl is awake," Momcubus remarked from nearby, folding her arms and walking out of the shadows.
