Twilight Velvet crawled obediently as she felt her Master tug on her reins. She cautiously peered up around her Master’s legs, wondering what the promised surprise was. She felt her heart leap at finding her son waiting for them. Kneeling on the floor beside him, held by her bridle, was an alicorn princess and her daughter-in-law, Cadance.
 
Her Master chuckled at her show of excitement. “Down, girl,” Master Night Light chided her, giving her reins a commanding tug. “You need to set an example for your slave daughter.” He waved his riding crop at the other mare crawling by his side. Twilight Sparkle rubbed her thighs together eagerly, but was otherwise the picture of a perfect sex slave. It was only to be expected. Twilight Velvet had trained her up personally.
 
She has also trained her up to become one of the best switch doms, feared by all subby stallions and mares across the Society. But that was something for another scene, another night. Tonight, they were playing the submissive mother and daughter slave routine.
 
“Here you go, son. This slave’s all yours. Don’t say your dad never gave you nothing.” Twilight Velvet snapped out of her reverie as she felt another tug on the bit gag in her mouth. This time it was Night Light giving her reins over to his son. Velvet trembled at being handed over like a used rag, to her son no less. She could feel her nethers drip with anticipation at the thought.
 
“You sure? Isn’t she your prize cocksleeve? She’s worth, what, nine hundred brands?” Shining pulled her reins, forcing her to look up into his eyes as he clutched her chin in his hooves appraisingly. Unlike his father, Shining’s acting was a little stilted, earning him an eye-roll from his wife. But there was nothing fake about his grip on her. He truly appreciated the feel of her face, her neck, her curves, her everything.
 
“Double that, actually. Most expensive slave in the Society,” Night Light chuckled at the sight of his son exploring his slave’s body. “Her market value shot up when her slave offsprings got collared.” He tugged on Twilight Sparkle’s reins, causing her to squirm with excitement. “You’ve probably also heard of her other daughter slave, Gleaming Shield.”
 
“Oh, I might have heard, yeah. She is a pretty loud bitch after all.” Shining Armor chuckled. Velvet, her daughter and daughter-in-law couldn’t help but stifle a giggle of their own.
 
“Everypony likes a broodmare that produces quality slaves.” Night Light nodded. “Hence why I’m giving this slave to you.”
 
“Ah, you want me to breed her?” Shining’s delivery was even more stilted, this time a result of the obvious excitement in his voice.
 
“Smart boy.” Night Light nodded. “By the way, these breeding chambers we’re going into are secured by a code hidden in these pregnancy test kits.” He tossed Shining a box labelled ‘CTRL’. “You have to get one of these to test positive to reveal the code to the door.”
 
‘Wait, when did he steal my experimental kit….oooh, the sly bastard!’ Twilight Velvet pouted up at the sidelong apologetic grin her husband shot her. ‘He’s so getting the dragon strap-on next time it’s my turn to dom!’
 
“So it’s a race then?” Shining chuckled.
 
“Last one out’s hosting the foal shower.” Night Light nodded. “The breeding chambers have two months’ supply of everything from food to estrus potions, in case it takes you that long.”
 
Velvet’s mind raced. They will be locked in the breeding chambers to get bucked, bucked and bucked some more until one of them manages to get bred successfully. Her nethers weren’t so much dripping as trickling as her petals winked uncontrollably at the thought. From the trembling and heavy breathing she felt from the alicorn slave next to her, she was not alone in her excitement.
 
“I’m more worried about you. Think you can keep up, old timer?” Shining nudged his father in the withers.
 
“I’m a sporting dad, so I’m letting you have double the chance of getting out.” Night Light nodded at both Velvet and Cadance. “That said, between my stallionly prowess and this slave’s talents, it’s barely a handicap.” He nodded down at Twilight Sparkle who smirked back up at them. Velvet knew her daughter loved a good test. “Hay, you might have to bring out Gleaming Shield to even the odds.”
 
“Heh, you’re on, old man.” The two competitors knocked hooves before pulling their respective slave teams into their breeding chambers. Velvet aimed a sidelong glance at her companion slave. Cadance smirked back. It would appear the young alicorn upstart was up for a little competition of her own. And Velvet was not above putting these youngsters in their place and showing them how it’s done.
 

 
A little something in celebration of Clocktower Society’s third anniversary!
 
 
By the by, you might notice I re-used part of my line-art from an old piece of art to save time coming up with Shining’s pose.
