Starlight watched Chrysalis fly off and decided that she was going to be a threat, and shot a spell at her, catching her in the back of the head, causing her to fall forward onto the ground. She quickly teleported herself and Chrysalis out of there and to the old castle's dungeons to reform her in her way, by destroying the mind and giving it a new purpose.
After getting situated, she heard a soft groan from Chrysalis as she started to wake up. Starlight walked up and said, "Hello my slave, you finally woke up." She wore something that was a cross between a lab coat and a bondage outfit. With every step, there was a soft click of metal hitting metal, her breast hung out and was made completely perky was a mesh that looped around in case it was needed."
Chrysalis shook off the shock of the outfit and said as she spat venom at her, "What is the meaning of this. Unhand me before this gets ugly, you have no right to handle royalty this way. "
A good slap across the mouth silenced her. She just stared at her with shock, unsure what to do now. Starlight grabbed her muzzle and said as she plucked the crown off her head, "I will have none of that. I did offer you friendship before, and since you declined that, I'm going to go with an alternative route, turning you into my sex slave." The rage overcame the shock and as soon as her horn lit up, she brought a riding crop down on it.
Chrysalis' body shook as the spell sputtered out. She fell to the floor and looked up at Starlight, the rage was still there, but it was dwindling compared to the other feeling running through her, arousal and fear. She took a gulp and said, "What are you doing, you do know stopping one's magic is dangerous?"
Starlight just grinned and said, "Only if it's done incorrectly, and don't worry, I'm not going to keep doing it, I just did that to keep you from using magic." A collar appeared in her hand and she added as she walked towards, "This is what I'm going to use to redeem you."
Chrysalis tried to back up, but she was against the wall, but it was no use. the collar clasped on her neck and she slightly winced. After a few minutes, she opened her eyes and looked at it in the broken mirror while fiddling with the ring in front. She turned to Starlight and said, "If you wanted to play dom, you could've just told me, I just happened to be a switch, but main with being the dom." She stood up to her fullest height, she added as she looked around the ruined building, "So is this my sub outfit, or do you have it somewhere?"
Starlight dropped the riding crop into her hand and said, "That's not it and your outfit will come after we're done." Before Chrysalis could question, the collar sparked before releasing volts into her neck, she screamed as she dropped with her back on the tiles. After the writhing ended, she added to answer the unspoken question, "That collar on your next will electrocute you into your new form, or should I just fry your mind completely."
Chrysalis growled and said as she tried to run at Starlight, "I'm not going to change, I'm the queen of the changelings." Before she could get up to her feet another jolt ripped through her. She added through clenched teeth, "I'm never going to surrender to you or the worthless princesses."
Starlight sighed and said, "guess I'm destroying you." the jolt grew stronger and her screams tore through the castle. After it was done, there was a bit of drool and smoke coming out of her mouth. She bent down and prodded her while muttering, "I think I overdid it."
She jumped back when she started to stir. Chrysalis wiped the drool from her mouth, and said, "I'm sorry, mistress, please use me as you wish." she fell to her knees, making her breasts jiggled and the collar clank against itself. Starlight walked over to her and slightly lifted her face while clearing the loose main out of her eyes. The rage that was there was completely demolished to the point that there was none left.
Starlight stood up and said as she tossed her riding crop, "If you're truly sorry, why don't we go have some fun. I'm sure there's a cushion for me while you satisfy me." Chrysalis stood up and wobbled after Starlight as she headed up the stairs.
After looking through a few of the rooms, she came across one of the princesses' bedrooms, it was in so much disarray that it was hard to tell who's it was, but the mattress was somehow still in good condition. She fell on it and thought about taking a nap, but she was too excited to sleep. She called out as she took her panties off, "Slave, I'm in here."
Chrysalis slid past the door and knelt in front of her.
Starlight added as she opened her legs, "I want you to lick my pussy."
Chrysalis didn't say anything and just went to town on her pussy, Starlight moaned as she lay down on the old mattress, taking in the slut's expertise in giving pleasure to others. She grabbed her horn and pulled her head more into her pussy. Her fingers were losing their grip, due to the pleasure going straight to her brain, she quickly wrapped her legs around her new slave and laid back as a brain-shattering orgasm hit her hard. She screamed in pleasure and said as she fell back, "That was amazing, fuck."
She was about to fall asleep, when she heard Chrysalis say, "That could be arranged." Starlight opened her eyes to see Chrysalis standing there, sporting a stinger-looking dick. Before Starlight could say anything, Chrysalis grabbed her legs and penetrated her pussy.
Starlight moaned and she dug her fingers into the bed and said between moans, "Yes, fuck me like the breeding slave that you are." She flipped over and let Chrysalis go crazy with fucking her.
She lost count of how many orgasms happened between the two of them, and when she passed out, but she woke up to the evening sun shining through the broken window over her head. She looked over to see Chrysalis snuggling into her side, with a content smile on her face. She slid her legs on the bed and started to walk funny back into the main room to pick up the items that were strewn about until she came across the box that she was hiding in the first place. She levitated it after her and headed back up to the room.
Chrysalis was awake and stretching out her limbs when Starlight re-entered the room. She looked over at her mistress and said as she walked up to her, "Hello, Mistress, what do you have in that box of yours?"
Starlight shivered with pleasure from that, and said while trying to keep her composure, "Our items, and your new outfit." She tossed the rest of the items onto the bed and pulled it out of the box. It looked like a nurse's outfit, but it was black with dark purple trim on the opening, her cutie mark was on the left side, and it had Chrysalis' name under it.
Chrysalis pulled it away from Starlight carefully and said as she examines it, "It's cute and better than that ragged look of a dark queen. did it come with any other items?" She reached into the box and pulled out what looked like a dog tag with nothing written on it. She looked at Starlight and asked with a confused look, "What's this?"
Starlight just smiled and without saying anything, just grabbed the dog tag and clipped it to the collar. The collar vanished from sight. She giggled at Chrysalis' surprise and said as she tossed the box on the bed, "It has an invisibility charm on it that works on the collar, we wouldn't want the patients at the hospital to see it, now would we?"
Chrysalis showed a look of concern and said as she started to put the outfit on, "So I'm going to be working at the hospital, are you sure that's a good idea. I mean, ponies are still scared of me and I don't think I'll fit in."
Starlight rubbed the top of Chrysalis' head and replied as she got dressed, "It'll be fine, and why not start big on telling the world that you're a new mare, plus if you ever revert to your old self, that collar will straighten you out. Think of it as a reformation and you get feed from the ponies your help. Now hurry up, we have things to do before that day's over." She headed to the front door, as Chrysalis cursed and started stuffing their items into the box and ran after her mistress.
She turned the corner to see the four princesses standing there in the doorway. She quietly cursed her luck and heard Chrysalis whisper in her ear, "You did say to start big, and what can get bigger than confronting the princesses about making me your slave and setting me loose on the hospital." She needs to correct that tongue on her slave, but that might be after this is over.
