> Simulated Depravity > by Shakespearicles > -------------------------------------------------------------------------- > Changing It Up > -------------------------------------------------------------------------- "So, I was thinking..." Princess Cadance said, sitting at the dinner table, across from her husband, Prince Shining Armor. 'Uh oh,' Shining thought. Whenever she starts off a conversation with that, it usually meant something bad. "I was thinking about inviting another mare into the bedroom," she said. Shining nearly choked on his broccoli. He coughed and sputtered, finally managing to swallow his food. "W-what!?" he asked with a start. "I said 'I was thinking about inviting another mare into the bedroom'," she repeated. "I heard you," Shining said, "I was just surprised. I didn't think that you would- that you were... into that." "Well, you know I've always been a little adventurous," she said with a smirk. "I was just hoping that my days of filly-fooling didn't have to end with being married. So I wanted to talk to you about it." "Oh." "I just thought that this was every stallion's dream. But we don't have to if you don't want to," she said with pouting eyes. "Yes! I mean, no. I mean, I want to do that!" Shining said, trying his best to not do a back-flip out of sheer excitement. Cadance clasped her hooves and smiled. "Perfect." She resumed her meal without another word. Shining sat there, stunned for a few minutes. "So... we're going to do it?" he asked. Cadance looked up from her salad. "Mhmm," she hummed as she chewed. "When? Who would it be?" he asked, impatiently. Cadance smirked. She finished chewing and wiped her mouth. "You just let me worry about the details," she said. "I'll set everything up for this weekend." "Okay!" Shining said. His cheeks were beginning to ache from smiling so hard. His end of the table began to rise from the fierce erection he was sporting from the thought of it. The weekend couldn't come fast enough. And right then, neither could he. He reached under the table to relieve his condition. "Ah ah ah!" Cadance scolded him. "Don't you dare! Not until later!" Shining reluctantly took his hoof away from his throbbing member. The prospect of abstaining for a few days would be worth it if it meant having a three-way, he decided. At last, the big night arrived. Cadance had just stepped out of the bathroom. "Shining," Cadance said as she toweled off, "our guest should be here soon. Why don't you take a shower too and freshen up for when she arrives?" "Okay!" Shining went into the royal bathroom and bathed, making sure to scrub everything thoroughly. After all, nopony wanted to felate a smelly stallion. Afterwards, he toweled off and brushed his mane to perfection. He spritzed himself with a bit of cologne and looked himself over in the mirror. His erection was standing at full attention in his excitement. But he didn't mind. This would be an occasion to show it off. "Shining!" Cadance called from the bedroom, "Our guest is here! Why don't you come out and meet her?" He smiled in the mirror. "Here we go." He turned and walked out of the bathroom. Or rather, he strutted. It was the kind of swagger that only came from a stallion that knew with utter assurity that 'I'm gonna get laid!' He strutted into the bedroom. There, on their massive bed, lay Cadance, grinning. And there beside her was another mare with purple fur, and a violet mane. "Twilight!?" Shining gasped, grabbing a pillow to hide his erection. "What's going on?" His surprise turned to confused anger. "Oh, I see what's going on! Ha ha, very funny Cadie. But this prank is a little much, even for you!" He said, shifting uncomfortably in the doorway. "Shine, what are you talking about?" Cadance asked. "It's not very nice," Shining said, "teasing me like that all week with the promise of having a three-way, and then having Twilight be here to laugh at me when it turns out to have just been a trick! Were you in on it Twi!?" he accused. Cadance and Twilight looked at eachother. "It's not a prank, Shiny," Cadance said. She patted the space on the mattress, inviting him over. Shining recoiled. "Cadie! Come on! I'm not going to- We're not going to do- that with my sister! EWW!" Shining scoffed. "Surely you can't be serious!" "I am serious," Cadance said, "And don't call me Shirley." Shining continued to stand there in disbelief. The joke had gone far beyond the point of being funny. "Fine then," she said. "If you don't want to join us, you can just stay over there and watch." She motioned to Twilight with a come-hither look. Twilight crawled across the bed as Cadance spread her legs, giving her access. Twilight's face vanished between Cadance's thighs, eliciting a moan from the pink alicorn. "Mmmhhf..." "Twilight!" Shining shouted. He couldn't believe his eyes. He rushed over to the bed. Sure enough, she was going to town on Cadie's marehood, happily licking and slurping away and wiggling her purple rump at him. "I can't believe this!" Cadance rolled her eyes. "Alright, alright, you got me," she said, shooing Twilight away. "S-so your not- we're not- buh b-but she was just-" Shining babbled, still seeing Cadance's wetness dripping from Twilight's chin. "I mean this isn't actually Twilight," Cadance said. Her horn lit, and with a soft pulse of magic, Twilight's form peeled away, revealing the changeling. "A changeling?!" Shining said. "I have a name, you know," she said. "Shining, this is Ocellus," Cadance introduced. "Hello... Ocellus," he greeted. "Charmed," she replied. "Okay, so, a changeling!?" Shining asked Cadance, seeking an explanation. "Shining, we can't very well just go out into the city and pick up a random pony. We're royalty. A rumor like that could be very damaging," Cadance explained. "Ever since Thorax assumed rule over the changeling kingdom, he has encouraged them to go out and... feed on love through more polite means than by conquer or subterfuge. I sought out Ocellus's... services for this occasion, with the promise of discretion." "Discretion is my first rule," Ocellus said. "Your celebrity gossip tabloids are no concern of mine." "Thank you," Cadance said. "Okay... I get that part," Shining said. "But... why Twilight!? Why my sister!?" he cringed. Cadance blushed in embarrassment. "Well..." she started, trying to find the words. "Twilight and I may have fooled around a bit in the past." "What!? When?" he asked in shock. "Years ago, when she was younger. Before she moved to Ponyville. She was still figuring out who she was and what she liked. So, yeah. For a little while," Cadance said, turning a deeper shade of red. "Again," she said to Ocellus, "this doesn't leave the room." "Of course," she affirmed. Shining was still reeling, even more so from the news of his sister's first experience with his (now) wife. "Alright. Alright, fine," Shining took a breath. "All that aside, though, why this now? Why have her be Twilight with us? With me!" Cadance couldn't hide her coy grin. "Well, I've kind of always had this... thing," she began to say, "I've always had this little... fantasy of you two, together." "Ugh! Cadie! I feel like I don't even know you! Wuh- why!?" he asked. "Shining, please!" Cadance begged, feeling hurt. "It's just that, since, you know, I've been with both of you. I know what each of you are like, in bed. And I just sort of think about what it would be like if you two... you know." "And that turns you on!?" he asked, incredulously. Cadance's smile fell and she just shrugged in guilty shame. "Well... yeah," she admitted. Shining was in a daze. He slumped and sat on the floor. He didn't need a pillow any longer. His erection had wilted completely, vanishing back into his sheath. "Ohhh, you two are really bumming me out," Ocellus said. "Shining, I love you!" Cadance said. "If you don't want to do this, you don't have to!" "But you want me to?" he asked. "I do! Shining, look, it's not really her. Okay!? It's just pretend," she said. Ocellus shape-shifted back into Twilight Sparkle. "Yeah, come on b.b.f.f.f!" she said in Twilight's voice. "Uh, its b.b.B.f.f. Big brother Best friend forever," Cadance corrected. Ocellus visibly counted out the letters. "Be, be, BEE, eff, eff... got it!" she said. "Shining, I sent Ocellus to spend time with Twilight all week, to learn all about her. Her appearance, personality, and mannerisms. I told her it was for her to be able to study changelings." "Which she did. But it was also reconnaissance for me," Twilight said. "Win, win." She put on her best seductive look. "Shall we engage in sexual coitus now, brother? I've read a book about this!" Shining couldn't help but smile a little. "That is endearing, disgusting, and probably exactly what she would say," he sighed. "You know, that is if she was going to proposition her own brother for sex." "I got every part right. Look!" she turned around on the bed and flagged her violet tail, revealing her moist, purple marehood to him. Shining reflexively averted his eyes. Not normally wearing clothes, a pony's privates were only ever occluded by their tail, but still easily visible to even a cursory glance of the eye. It was just polite to not look. Although admittedly Shining had, as a curious colt in the past, stolen glimpses of the female privates in his home. Forcing himself to look now, he mentally admitted the success of her accuracy. Cadance moved over to her and grabbed her rump with her hooves, giving her pussy a lick. "Ooh!" Twilight yelped. "She even got the flavor right!" Cadance said. "Cadie-" Shining scolded in resigning frustration. Cadance stopped and took Shining by the hoof, pulling him up onto the bed beside Twilight. "Pleeease!?" Cadance begged with those doe eyes she knew that he couldn't resist. "This really turns you on?" he asked. "Oh, like you would not believe!" she said. He looked back at Twilight and winced, trying to remind himself that it wasn't actually her. "Ugh..." he groaned. "This is so weird. But if it's what you really want... I guess I'll do it." *Squee* Cadance practically pounced on him, pinning him onto his back. "Thankyou-thankyou-thankyou!" she squealed, immediately diving between his legs, licking and teasing at his sheath. Cadance had always been willing to engage in fellatio in the past. But he had never before witnessed her initiate it with such eager gusto. He felt the blood rush to his stallionhood so quickly it almost hurt. In seconds he was already at half mast. The other mare joined her. He felt his stomach do a flip as she leaned in on the other side of him to lick along the side of his shaft with Cadance. "It's not really her. It's not really her," he mentally repeated to himself as Twilight helped his wife lick along his length. He shut his eyes and just tried to focus on the feeling. He had never had two mares servicing him at once like this. Objectively it felt amazing as two mouths and tongues pleasured his shaft and balls, alternatively sucking on his tip. With his eyes screwed shut, it didn't matter who it was doing it. It could have been a stallion doing it. "No no no! That's not better! Bad brain!" He hazarded to open his eyes briefly, if only to confirm to his brain that it indeed wasn't a male down there. Cadance was busy gently sucking each of his balls. He caught eyes with Twilight, bobbing her head on the end of his dick. He felt a twist in his gut and genuinely felt mentally conflicted whether it indeed would have been worse to have seen his sister or a guy. And at the same time, it felt amazing. Twilight was swallowing his dick and sucking it like she invented it. "Mmmff," Cadance moaned into his balls. He looked over at her and he could see that her hoof under her body was clopping herself silly. She really was getting turned on by all of this. Shining grit his teeth. As much as he didn't like carrying bags, or taking out trash, or changing Flurry's diapers at two in the morning, he did all those things for Cadance because he loved her. That was why he was doing this. It was for Cadance, he reminded himself, and it was just pretend. "He keeps closing his eyes," Twilight said. Cadance looked up at Shining, with his eyes closed again. "Hmmf!" Cadance huffed in frustration. The entire point of the fantasy was for him to be aware of what he was doing. But barring that... "Fine, if you don't want to watch, you can at least participate." She crawled across the bed over to where he was, and stood over him. Shining looked up above him in time to see his wife squatting down on his face. Her tail filled his field of view as she mashed her sopping pussy against his snout. He needed no further direction, happily lapping away at her familiar flavor. He felt the weight of the other mare shifting off of the bed. Cadance took his dick in her magic, aiming it upwards. He expected to feel his wife's mouth on him in this position. But then he felt a weight climbing back onto the bed and a hoof on either side of his waist was the other mare lowered herself onto him. Cadence helped to guide his tip to Twilight's pussy, rubbing it against her, getting it slick with her wetness. She applied a bit more weight, and he felt himself pop into her, a barrier giving out to his penetration. She had even managed to simulate a hymen, he realized. She sat down, sinking his length into her until her hips met his. "Oh, fuck!" Cadance trembled as she straddled his face. He couldn't be sure if it was from him licking her pussy, or from watching his white cock vanishing into Twilight's lavender pussy. "Yes! Ride your brother's dick!" He strongly suspected the latter. Twilight began to hop up and down on him. Shining tried to focus on pleasing the mare sitting on his face. He ran his tongue back and forth along her slit, diving into her wet foal hole, and back to flicking her little love nub, giving her little shivers of pleasure. "Ooh, my brother's dick is so big!" Twilight said, playing into the role, "He's gonna make me cum!" Cadance shuddered and cried out on top of Shining as her legs squeezed the sides of his head. His mouth was flooded with her marecum as she climaxed. She was clearly enjoying the spectacle. Twilight continued to slide up and down on his shaft, grinding against his hips each time she came down, tensing and flexing her pelvic muscles. He could feel himself getting close. And she could too. Twilight sensed him growing thicker inside her, signalling his approaching orgasm. His extra girth being the final bit to get her to the top. "Ah! Ah! I'm cumming!" she cried out. Her pussy trembled and rippled around his dick, milking him with her muscles, beckoning him to cum as well. Shining struggled for breath amidst his wife's flood. Her legs had his hooves pinned at either side of him. He called his magic to his horn to lift her from his face, gasping for air. She reached down with her hooves and took his head, adjusting it upwards before sitting back down on his horn, dispelling his magic in her warm wetness. Cadance's horn glowed, her magic surrounding his balls. He could feel her warm magic on him, causing his balls to swell and churn with extra volume of potent semen. He felt himself nearing the point of no return, but in his new position he was forced now to look at Twilight. He could smell the musk of a mare in heat wafting from her. He felt that pang once more. An internal conflict of the pleasure he was feeling, and the sight of his sister giving it to him. Twilight felt him flare inside of her. "He's going to cum! He's going to cum inside me soon!" Twilight said. Cadance came again at hearing those words. Her legs gave out and she tumbled backwards off of him, freeing his horn once more. Out of the corner of his eye, he saw Twilight standing in the doorway. "Twilight!?" he gasped, seeing his sister having walked in on them in the middle of such a lecherous act. "Shining?" she asked from the doorway, confused, seeing a copy of herself having sex with her brother. "It's not what it looks like!" He cried, "It's a changeling!" With his last ounce of strength he threw magic at her with his horn, to dis-spell her disguise. The Twilight riding his dick had the spell hit her, and buffer off as though nothing happened. The Twilight in the doorway shimmered and turned back into Ocellus the changeling. "What the hell!?" He looked back at the Twilight riding on his cock. The real one. "Surprise," she said meekly. "TWILIGHT!?" He screamed. "We switched when you couldn't see," Twilight said. It had been her plan all along, with Cadance's help. Cadance moaned from the most powerful orgasm she'd ever had, at his revelation. "This is so fucking hot!" She climbed back on top of Shining's horn. Her pussy gushed marecum down his forehead in hot torrents, keeping him from being able to use his magic any longer. Her weight kept his hooves pinned down. She leaned over and kissed Twilight deeply as she continued to fuck her brother. "Mmf! Yes! Cum inside me!" Twilight moaned, "I'm in heat!" Shining struggled to get free, but he couldn't. He teetered on the brink of ejaculating, fighting with all of his willpower to stave it off. "Do it Shining!" Cadance commanded, "Let it go." And cue the music "Let it go!" "How 'bout no!?" "He can’t hold back anymore!" "Let it go." "Let it blow!" "My mind and body are at war!" "Concentrate, don’t ejaculate, don’t let it blow, or else she'll grow!" "It’s funny how some resistance makes everything seem hot. And the fears that once controlled him, can’t get his shaft to not." "Up here on this hard thick cock I can finally conceive!" "I don't want to make my sister a mom, but I’m too restrained to leave!" "Let it go!" "Nooo!" "Let it flow!" "I can’t hold it back anymore!" "Let it go!" "Ooh!" "Let it go!" "On my back, inside Twi, to the core! And she's in heat, on top of my meat." "Let it go!" "Let it go!" "My heart is pumping like this swirling sperm inside. Couldn’t hold it in, heaven knows I tried!" "Don’t pull it out, just cum inside, just finish up, and end the ride!" "His cum churned white in his ball sack tonight. Now it's bursting from that thing!" "A kingdom of impregnation And it looks like I'm the King." "Twilight is moaning with his swirling seed inside!" "Couldn't hold it in! Heaven knows I tried!" "He let it go! He let it blow!" "He finally did the deed! "He let it go! He let it flow!" "Filled my desperate need!" "And here I lay! Helpless on this day!" "Filled my womb with his seed!" "Incest never bothered me anyway!"
