A new favourite child

As the carriage drove them back to Velvet’s house their mother talked animatedly to Twilight and Rarity about all sorts of topics. Most of them were girl-related conversation topics that Spike had no real interest in. Though whilst Velvet wasn’t paying much attention to her adopted dragon son Rarity had her hand intertwined with his, sending him a silent promise of many delightfully sinful things to do with her.

It may have been a good thing that Velvet wasn’t paying attention to him, as she missed Spike’s growing erection and his not-so-innocent stares of his mother. Rarity was only barely containing her own similar unladylike stares of her own.

When they arrived at Spike and Twilight’s childhood home, Velvet was the first out of the carriage, having checked both ways to make sure the coast was clear. From the roll of Twilight’s eyes, this wasn’t an uncommon practice with the new Sparkle family curse.

“Spike dear could you unload the carriage please? I don’t want to be left outside like this,” Velvet whispered before reaching a hand around Rarity’s wrist. “And I would just love to get to know your lovely girlfriend here.”

Before anyone could protest or complain Velvet had rushed inside, dragging Rarity with her. Spike sighed, having expected something like this to happen, fortunately, Twilight was a whole lot less shy about her body.

“Don’t worry Master, your lowly **** will handle the bags. Go on ahead,” Twilight said with a delightful little curtsy before levitating the bags, allowing Spike to rush on ahead and follow Rarity and Velvet into Velvet’s bedroom. He hadn’t been noticed and was able to eavesdrop on the two.

“You were quite eager to take me here. Something you want to discuss Mrs. Twilight?” Rarity asked, her eyes filtering to the crack on the door where Spike stood listening.

“Um yes actually. Twilight’s told me you’re quite the fashionista, has she told you about our family curse?”

Velvet’s cheeks grew a soft red as she said this, but Rarity didn’t have the same reaction as the mature woman. Instead, the perverted cogs in her mind began to spin. “Yes, but she wasn’t referring to it as much of a curse.”

Spike could see Velvet frown as she said that. “Twilight used to be a much sweeter child until Cadence got her claws in her.”

Rarity did a double take at the hostility directed at Cadence, as did Spike. She had always liked Cadence but making Cadence a slut seemed to have soured her approval of her. Spike remembered that before the Root of Honesty had made Twilight idolise Cadence it had made her disapprove of the new slutty Twilight.

“In any case, I was hoping you might be able to fashion something a bit more conservative for me. I know the curse makes this difficult but could you see what you can do please?”

Rarity stroked her chin, deciding how to twist this to her advantage. “I’ll see what I can do to help. But I truly don’t see how it’s a problem. Your daughter does well with her curse, I would say it’s more of a blessing really.”

A bright blush of rage, unfamiliar to Spike, came across Velvet's face face. "She's been corrupted just like my dear Shining Armour by that whore. They’ve both been stolen from me, Twilight’s life ambition now seems the biggest slut she can be, and I just know that she’s cheating on poor Shining.”

Shining, not Gleaming Spike noted. Of course, whilst Gleaming believed otherwise she’d be changed by a potion, not by the Root of Honesty. Outside the Crystal Empire ponies still knew Shining Armor and not Gleaming Shield.

Rarity picked up on that too but didn’t press it. Instead, she elegantly danced around Velvet until she was behind her, two hands massaging the mature woman’s shoulders, calming her. “You shouldn’t be too hard on Cadence dear. It’s in her nature, you know she has trouble being satisfied by a single pony. I’m sure you can relate.”

Rarity’s eyes flickered towards Spike’s direction as she said that and he got the hint. Whispering to himself he said, “Does Twilight Velvet have the same issue as Cadence in the bedroom?”

Spike then realised that he probably didn’t want Night Light to suffer much so he added, “Does Night Light not care about sex?”

Velvet’s face, previously swept with indignation quickly became a red one of embarrassment. “That’s not the point. I’ve never needed to cheat on my husband, what do my children see in her?”

Rarity continued to massage her. “Calm down dear, everything will be all right. And don’t forget about Spike. You still have him, though I hope you don’t mind if I have a piece of him.”

“Yes, Spike is a darling young man,” Velvet admitted before perking up and clapping. "Sorry for bringing this up I just wanted to ask for a new outfit and here I am complaining about Cadence."

"Oh not at all dear, here let me fashion something helpful for you. It won’t be a perfect counter to your curse but it might help,” Rarity said before snapping her fingers and a bundle of clothes appeared on Velvet’s bed.

“That’s an impressive bit of magic. Thank you, dear.” Velvet glanced up at the clock and gasped. “Oh dear the time, I need to get dinner ready, excuse me.”

Spike was able to back up against the door so Velvet didn’t notice her, but Rarity didn’t. “Thank you for the support, Master.”

“No problem, something tells me that you’ve got something in mind.”

The unicorn smiled coyly, “I may have something in mind, Master. Shall I take the lead and you support me with your power.”

“Sure. Seems you’ve got a plan.”

“Oh, I do darling. When I squeeze your hand make it so what I say always come true for the rest of the day.”

They made their way down to dinner, with Velvet fetching them something quick. Night Light had also made his way home and had struck up a conversation with Twilight. Soon their food was made and the family began to discuss different things. Topics like the reason for their visit to Canterlot, Twilight’s studies and Rarity’s relationship with Spike. They had to lie of course, but neither of Spike’s parents saw through them.

Soon, after night had fallen, dinner had finished and Twilight had volunteered to help. Leaving Rarity, Spike and Velvet alone, a squeeze of his hand gave the signal. “Will everything Rarity says come true until she goes to sleep?” Spike whispered.

With a pleased grin, Rarity rested her chin on her fingers. “So Velvet I hear that you’re a writer. As a fellow creative mind myself I have to ask what kind of stories do you write?”

Velvet beamed as her face was overcome with a passionate enthusiasm that rivalled Twilight’s, Spike almost believed he heard a squeal. “Oh, I write about a great number of things. I love for my stories to be daring, and exciting so I’m drawn to writing adventure novels mostly but I can’t help myself from adding a splash of romance to these books. I’ve actually started on-“

“And porn?” Rarity interrupted causing Velvet’s face to turn scarlet. “Do you write a lot of porn dear as well?”

“Umm yes I do, but I’m much more of an adventure writer,” she said with a cough. Her gaze shifted to the side. “My newest adventure-“

Rarity interrupted her not-so-subtle attempts to change the subject, however. “You love writing porn, far more than you love writing anything else. But you keep it a secret from your husband don’t you?”

Twilight Velvet continued to squirm, her face getting beet red. Eyes darted to her husband who was still obliviously washing dishes with Twilight.

“You can’t tell him,” she gasped, panic-stricken.

“Don’t worry darling. Your husband will always be naively oblivious to anything sexual you do. In any case, I bet you just love writing porn more than anything else.” Rarity was thoroughly enjoying herself, watching Velvet’s face scrunch up as her values as a writer clashed with her newfound love of porn.

“I bet you just love writing all sorts of smutty, depraved porn don't you dear? I bet it's extremely popular as well. Now tell me am I right in thinking that the porn centres around a sexy MILF and her adopted dragon son. Doesn’t that sexy MILF love to spoil her dragon son rotten? Doesn't that MILF love to provide her dragon son everything he could possibly want, even beyond reason? Can the dragon not do anything wrong in the MILF's eyes? Doesn't she want her adopted son to have his own harem? Does this MILF spoil her dragon son by making her daughters into his harem slaves? Would she be willing to cheat on her husband to make this happen?"

"I see you are a fan," Velvet gasped, her face darting to Spike's as it grew as white as a sheet in embarrassment. Sensing that it was best that he leave Rarity to this on his own, he got up.

"I'm heading to bed, see you later." His eyes glanced down at Rarity's, a silent promise for her to tell him everything later. She gave him a silent nod. Now alone with Velvet Rarity became more predatory. "I bet you based the dragon in your story off of Spike, and MILF off of yourself."

Velvet gulped visibly. "Noticed that didn't you?"

"I bet deep down that's one of your deepest desires. To be that MILF, to treat Spike that way. You've always spoiled Spike that way, haven't you? Thought he could do no wrong. He was always your favourite and his happiness was your happiness. Even if he remembers things as he did before this conversation." Rarity had whispered that last part under her breath, she didn't want Spike's memories to change at all. "And I bet since he became an adult you've developed a crush on him. I bet you just want to act out all your fantasies from your story and are just waiting for him to make the first move."

"H-how do you know all this?"

Rarity simply shrugged. "You're going to forget this conversation when I leave this room, but everything from it will still be true."

Leaving Velvet gaping like a fish, Rarity made her way out of the kitchen, her hips swaying as she did so. She made her way to her Master's childhood room, where the two of them would be sleeping.

"You did something, this room's changed," Spike said as she entered, gesturing to the room. "The bed used to be a single bed, it certainly wasn't this clean before, and the computer wasn't that expensive."

"Oh, Spike I think you'll find that many things about your life have changed." She tapped him seductively on the chest. "But I'm sure you'll like them."
