It was getting harder and harder to think. And worse, Twilight didn’t want to. It was easier to lay helpless and keep breathing in the pleasant, pungent gas. She licked the condensation gathering around her lips as she started taking deeper breaths. Ropes dug into every nook and cranny in her body, from the back of her knees to a camel toe she was unknowingly showing off.

“Don’t worry,” Silver said, “I’m not going to leave you here all hot and bothered. That would be boring. I’ll take good care of you. Diamond wanted to, but like I said, she’s with Radiance right now. After they’re done bonding, Diamond is going to set up an auction for who gets to know your secret identities. The highest bidder gets to keep you as their pleasure mares. Last I heard, the Prankster was at the top of the list.” Silver laughed at the idea of Manehattan’s homicidal clown pony owning the leader of the power ponies as a sex slave. “But you get it now, what the gas is doing? And what I’m going to do?” Silver raised her head simultaneous to a stallion grunting lewdly somewhere in the distance. “It won’t be long before you’ll be happy to tell me Radiance’s real name to me, then the names of the other power ponies too, and maybe their friends and family.”

Tarnished Silver raised one hoof to her head, removing her purple visor. She grabbed Matter-Horn by the head, staring right at her captive.

Matter-Horn took one look into the shifting colors of the empath’s eyes before remembering exactly how Tarnished Silver’s powers worked. Closing them to avoid the power of mental suggestion—it only took a second for the horned heroine to feel Silver’s power increase the warmth spreading in her body, making Twilight feel the need to have her body touched and rubbed all over.

“You’ve never had a dick inside you, have you?” Silver asked.

The question fueled the lust permeating Matter-Horn’s mind. She could imagine something thick and hot pushing inside her, consummating that full and complete feeling. Tarnished Silver was right—Twilight had never been with a stallion before.

“Nah, not a pony like you,” Silver continued in a mocking tone, “You’re one of those mares that’s so full of herself when she’s at work, but totally the opposite when the costume comes off. I know the type, use to pick on you losers in school. Your only accomplishment is what that costume means to others. At the end of the night you’ll still go home to an empty bed, only your right hoof for company.” Silver frowned, imagining how sad and lonely such nights could be. That same loneliness overcame Matter-Horn fidgeting in the ropes as she imagined nights alone in bed, grinding against the pillow she would hug at night, pretending it was really some wonderful stallion waiting with a loving smile for her to come home from a night of crime fighting.

As those thoughts took over Matter-Horn, the whirlpools of color in Tarnished Silver’s eyes moved faster, deepening the emotional assault. Silver could tell she was in Matter-Horn’s head now, and the special gas was oxidizing in the Power Pony’s blood with every breath.

“I can understand that; wanting to be someone else outside of the costume. To be special without wearing a mask and hiding who you really are. Just keep breathing. Long, deep breathes… you don’t need to be a Power Pony. You’re just a mare. A mare who had one too many nights going to bed alone, going out at night to risk your life rather than going out on dates. Isn’t that right?” Silver asked.

Matter-Horn tried to nod or do anything to look away. Her eyes were half open as they stayed locked on Silver’s. She hated it: going to bed alone all the time, never having any chance to be with somepony, or meet anypony that wasn’t a costumed criminal. And it was true, her right hoof never really satisfied her. Not in the same way she imagined a strong, pulsing, horse phallus could. Simple rubbing could never replace the sensation of being plugged with something warm that made her overflow with pleasure. A load warming her belly and keeping her feeling full even after her partner’s penis popped out of her tight twat, ready for her to lick clean. It was a feeling she wanted desperately.

Wh-what… I’ve never felt that before… how do I know it feels that way?

The question weakened the illusion, bringing reality to her fantasy.

“Keep breathing, just like that," Silver said, "You know that smell, don’t you? It’s the smell of a stallion who wants you more than anything in the world. That’s a super power all mares have, to make a stallion want them and only them. Can you imagine it, hearing your real name being called out as the stallion lucky enough to mount you reaches his peak? Losing strength as he empties himself inside you?”

Twilight could hear it. Her real name being called out by a stallion with apple-red fur and hard, bulging muscles, pumping into her, trembling as her tightness, her heat, and her wetness encapsulated his member, pulling it deeper. She could picture the climax, all his impressive muscles tensing up as a last gasp escaped his lips and his hot jizz flooded her insides. He would roll off her in a sweaty mess, at her mercy, taken by pleasure only she could give, and his reward would be having their collective juices licked clean from his sensitive cock while he moaned her name in a deep, husky voice: “Twil-”

Wait… that’s not me! I wouldn’t do that!

It took effort, but Matter-Horn pulled her eyes away from Tarnished Silver’s gaze. She felt like she was only half awake, remembering fragments of a dream. Silver gasped, surprised for a moment, then laughed.

“Either you have some amazing will power, or you’re too horny for a fantasy. If the wet mark at your crotch is any clue, I bet you need a dick in you more than you even realize.”

Matter-Horn whimpered. With her attention free of Silver’s emotional influence, Twilight was ashamed to feel so aroused given her situation. She inadvertently took deeper breaths of the gas, her body showing symptoms. Her wings ached to be free. Her body had become more sensitive than she thought possible, and thanks to the tightness of her costume, she could feel herself winking. The ropes prevented her from turning her head, but she could feel her juices spreading under her costume, making the outfit cling to her even more.

I… feel so hot. Can’t-can’t keep my head clear…

“Am I right? Is the great, upstanding Masked Matter-Horn ready for a hard rutting? Or do you want to save yourself right now, and give me what I want? Tell me your friend’s identity right now… and I won’t have you fucked senseless.” Tarnished Silver brought her face down to her captive, looking Matter-Horn right in the eyes. Silver was reminded of how much she hated the power ponies, particularly Matter-Horn. Those feelings were shared with Twilight, helping distract her from the ache between her hind legs, but it also played into what Silver really wanted to hear.

“You won’t get away with this.” Matter-Horn’s muffled promised sounded weak behind the foggy oxygen mask. Tarnished Silver smiled in response, looking away from the power pony and cutting off her emotional influence on the mare.

“Oh, I just did. Remember when I said if you spoke out of turn, you’d make it worse for your friend? Well, you did that twice. That means you’re going to get two visitors, and your friend Radiance is going to owe Diamond two more hours of orgasms.”

Masked Matter-Horn looked afraid for the first time since her capture. Panic finally won out. “If you hurt Ra-”

Silver slapped Twilight again. The tightly strapped oxygen mask didn’t move. “That’s three hours now and three visitors for you! Unless you want more? You can totally speak up again, by all means.”

Matter-Horn stayed silent, the pain in her cheek fading away as its sting tingled with pleasure more than pain.

“Tarnishing your image with the spunk of three stallions is going to be so rewarding for me. It will feel even better for me when I hear you give up the ponies you care so much for.” Tarnished Silver laughed at the thought of doing what so many other villains tried and failed to do in the past—bring an end to the Power Ponies once and for all.

Silver moved behind Matter-Horn, grabbing her captive by her hind legs and spreading them apart.

“You’re soaking your costume... let me help with that.”

Matter-Horn could only shut her eyes as she felt Silver’s muzzle press into the warm, wet material of her costume, making Twilight squeal. She heard and felt Silver sniff at her, hard and exaggerated like a pony about to enjoy a fine meal, making her eyes water with tears from what was about to happen.

“You smell good,” Silver said, keeping her mouth close to the soaked sex of the Masked Matter-Horn. “Hey, can I tell you a secret? I utterly love the smell of superpony pussy. But, yours doesn’t smell as sweet as Radiance.”

Silver pushed her tongue out, dragging it firmly over the camel toe of Matter-Horn’s costume. The Power Pony squealed loudly, squirming to push her helpless snatch closer to Silver’s mouth, tears shedding as her body betrayed her.

“Plea-please… don’t do this…” Twilight tried to beg for Silver to stop as her captive licked harder, until she felt Silver’s teeth pinch her. Matter-Horn yelled out, feeling the teeth graze her covered flesh and fasten onto her costume, pulling at it.

Tarnished Silver yanked back hard, ripping Matter-Horn’s costume and exposing the warm source of wetness. Silver pushed her muzzle back into the bare, winking sex of the Masked Matter Horn to take a longer, shameless sniff of Matter-Horn’s sex.

“Gods…” taking a long drag from Matter-Horn’s swelling clit to her smooth anus, Silver announced, “You’re actually dripping on my muzzle, you naughty mare...” It was true, despite what Matter-Horn wanted to believe. The lips of her achy sex winked again and again, leaking shame.

D-don’t… want this. This isn’t me… it’s the gas. Those awful things she made me imagine. I have to save Radiance… have to save Rarity!

Matter-Horn shut her eyes tight, trying to fight against her growing arousal. With her eyes closed, Silver couldn’t force her own feelings on Twilight, and even if she was raped right there and then, she still wouldn’t give up her or Radiance’s identities.

Tarnished Silver had no interest in playing mind games anymore. Her full attention was on her captive’s hot pussy, smearing juices on her nose and tongue. Silver licked again, loud and hungry for the unending supply of honey. She used the smooth edges of her front hooves to spread the petals of Twilight’s sex open, admiring the bright pink. Twilight gave a lusty moan as Silver pushed her tongue inside, deep as she could, loving how Matter-Horn squeezed around it. Silver’s lips locked tight around Twilight’s sex, sucking hard and sudden. Twilight struggled to remain conscious as pleasure radiated from her loins, seizing control of her body’s every action.

Silver didn’t hold back. She rubbed her tongue along the slippery walls of Twilight’s love tunnel. Mare juice was beginning to drip down her chin and throat as Silver pushed her tongue in and out of Matter-Horn, lacquering the walls of her foe in a syrup of spit, sweat, and pre-cum. Moans vibrated against Twilight’s sensitive sex, making her own oratory louder, joining in the chorus of the ponies she heard earlier.

As Twilight felt one of Silver’s hooves edge down to tease her clit, Twilight gave up fighting how good it felt to get eaten out. She tried pushing into Silver’s face, eager to take the full length of her captor’s tongue inside her. Silver grazed the horny heroine’s clit with her hoof, giving Twilight the push she needed to scream in pleasure and soak Silver’s face with one of the fastest orgasms she had ever had.

The tongue inside her finally stopped, and Silver slowly pulled away. Matter-Horn was left gasping, breathing great gulps of gas that hadn’t stopped blowing over her mouth and nose. The pleasure didn’t end, and Twilight felt too good to feel ashamed. She couldn’t feel Silver behind her anymore, but could hear heavy breathing and heavy steps behind—Matter Horn realized the steps sounded too heavy to be a mare.

“There she is, just lean your head forward. Sniff her out and you can have her.”

Matter-Horn’s eyes shot open as she tried to turn her head to see who Silver was speaking to.

Behind the bound heroine, a stallion in a gimp mask was led into the stall by Tarnished Silver, his reigns in her mouth, pulling him along. The gimp mask covered his entire head, his mouth sealed shut with a zipper, so that only his nose was left uncovered. His body shined from a black latex body suit that left only his lengthy spotted penis exposed. He sniffed the air, lowering his head more and more until it came to Matter-Horn’s cum-soaked rear. The sudden intruder made the helpless Power Pony scream, struggling and thrashing to pull away from the stallion as he took deep breaths of the musk-infused air, then stepped forward over Matter-Horn’s bound body. She hung low enough that he could mount her with ease even though he was unable to see her.

Matter-Horn screamed as she felt his hot stallionhood poke against her thigh. Even through her costume, she could feel heat emanating from the stallion's privates as he blindly fumbled around. Tarnished Silver giggled, amused at how one of her eager ‘pets’ rubbed himself over the helpless heroine.

“Poor guy’s so eager. He’s been hard for hours and hasn’t gotten to cum, even once. I wanted him hard and ready for you. He’s been breathing in the same gas you have.”

Matter-Horn shook her head as much as she was allowed, eyes shut as she felt the brute pierce her exposed sex, wet and winking against the smooth head of his own leaky cock. He let Matter-Horn feel his muscles tense as he found what he wanted, pushing firmly into her.

It was happening too fast. Matter-Horn screamed in pain and pleasure as the thick head of the stallion’s cock pushed apart her slimy pussy lips. She bit her lip until it bled, hating that her first stallion cock felt every bit as good as she had fantasized...
