"Greeting: Good afternoon, Master." A bot in the likeness of Dr. Ace Sorou stated, welcoming the good doctor back. Ace looked up, as he made his way over to the lab entrance, and nodded.

"Deebee-oh-four." Ace greeted, instantly recognizing the bot, despite the fact it looked just like all the other bots of it's type. The bot had a file in his hand, and he held it out for Ace to take.

"Statement: These are the reports you asked for, Master. Explanation: Every error, malfunction, and bluescreen within the last month has been cataloged, with accompanying details. Proud statement: Though there were few incidents, I've already taken the liberty of brainstorming possible solutions for each error. Recommendation: You may wish to look over them."

Ace took the reports and nodded at the robot with a smile. "Excellent work, Oh-four. Keep it up." He began looking through the file, beginning to be on his way.

"Addendum: Also, Master, miss Pie is awaiting your arrival down in the lab." The bot mentioned. "Message: She told me to tell you that she has something special planned."

Ace nodded. "Thank you, Oh-four." With the warning, Ace slowly descended the stairs, the file tucked under his arm. "Oh Pinkie?" He called playfully, keeping an eye out for the pink pony. However, he was surprised anyway. Pinkie had been laying on his desk, flicking her tail in annoyance. What caused Ace to be particularly wary was the fact that Pinkie's mane was completely straight. "Uh, Pinks?" He began. "Is everything-"

"Sit." Pinkie demanded, glaring at Ace, and pointing at his chair with her hoof. Ace quickly obliged, moving over to his chair, and taking a seat. He was sweating bullets, trying to think of a reason why his marefriend seemed so angry. When nothing came to mind, he looked up at her. His face was a perfect statue, despite his fear. He decided that he was going to deal with this as calmly as he could, and whatever Pinkie was angry about, he could handle. Or so he thought...

Pinkie was quiet for the longest time, fire in her eyes as she burned holes in Ace's face. She silently studied him, her snout twisted into a slight snarl as she calmed herself enough to think rationally, and NOT strangle him. She knew that she had to keep calm. 'Look for a reason.' She thought to herself, remembering the debacle with the MMMM on the Friendship Express. So despite her urge to tear Ace a new one, Pinkie began to speak.

"Ace," She began, in a frighteningly serious tone, quite unnatural for Pinkie. "When I woke up this morning, I had this super-ultra-funtastic idea to have the best date ever with you." She told him. "But when I came to tell you about it, you were gone. So I decided play a game on your computer until you got back."

Ace mentally went through his library of computer games, but found nothing objectionable. He blinked. "I don't-"

"I'm! Not! Finished!" Pinkie told him through gritted teeth. Ace immediately clammed up. "Now, I got a little lost trying to find your games folder. But do you want to know what I found instead?"

Ace didn't know how to answer this. Yes? No? Can I buy a vowel? There's absolutely no reason for her to be angry unless...

'Uh-oh.' Ace thought. 'Unless she found my porn.'

Pinkie saw the look of realization on Ace's face, and struck. "So tell me, Aceyyyyyy..." She said, venom dripping in her voice. "WHY ARE THERE PICTURES OF HUMAN MARES DOING LEWD THINGS ON YOUR COMPUTER?!?!?!" Shouted Pinkie.

"Pinkie, listen!" Ace said quickly. "I-it's completely normal for guys to look at that stuff in my world! Honest!"

"Normal?" Pinkie asked, her eyes dilating in anger. "NORMAL?!?!" Pinkie reached over to Ace's monitor, and shoved it in his face. On the screen was a woman laying down, covered in what looked like blood, and doing 'things' with the hilt of a knife. She wasn't wounded, but judging by the background, it was clear where the blood was coming from, even if the corpses were obviously fake. "HOW IS THAT NORMAL?!?!"

'Oh, great.' Ace thought. 'It's not just any porn. She found my fetish folder.' Ace put his hands up defensively "Okay, THAT'S not normal, I admit." He told Pinkie, trying to think of a way to explain the picture. "But hey, everyone gets their jollies from somewhere."

Not a good move. "Oh?" Pinkie asked, shoving the monitor back. "You don't get your 'jollies' from me?" She asked, stomping over to the edge of the desk, and glaring into his eyes. "I'm all sorts of jolly! What's the matter?! Is my jolliness not good enough for ya?!"

Ace shook his head furiously. "No, i-it's not like that at all!" Ace tried to explain. "There's a reason pictures like that get their own separate folder from the rest! It's a secret nobody can know!"

"I thought it was 'normal' for guys to look at lewd images." Pinkie dead-panned.

"It is, but I-" Ace shook his head, cutting himself off. "Pinkie, that kind of saucy image scares normal people." He explained. "It's only freaks like me who get off on that kinda stuff. I don't know why, but that is the sexiest thing a girl can do to turn me on. And it's because of that 'normal' people would throw me in a nuthouse! If I met that girl on the street, I'd appreciate her work, but I wouldn't love her! There's a huge difference between love and lust, Pinks! Yes, I like a girl who could kill me at a glance, but that doesn't mean she's gonna steal my heart!"

Pinkie was both angry and confused. Some of her worries were alleviated, but this still wasn't over. She pondered this information with a snarl, before asking, "Why?"

"Beg pardon?" Ace asked.

"Why do you 'get off' on this kinda stuff?" Pinkie asked clearly.

Ace hesitated, as he struggled to come up with an answer. He shrugged. "I don't know. It's called a 'Yandere' fetish." He told her. "Yandere means Psychotic Lover. To me, the sexiest thing a girl can do is be psychotic AND love me. A Yandere will be completely crazy, and completely head over heels for you. To me, what really clinches it is the fear factor. There's an element of danger to being with a Yandere that just attracts me like a black hole. When I know that at any moment, my lover can turn around and kill me, that causes me to have the best...sessions...ever!" Ace stopped, sighing, as his eyes began to water.

"Listen to me. I sound like a total freak." He said, sniffing, as he looked down, unable to look Pinkie in the eye. "I get where this is going. You probably think I'm too weird to be your coltfriend, now." Pinkie's expression softened at those words. "Y-you're the only one who knows this about me, Pinks. I-I know you're gonna leave me now, and there's nothing I can do to stop you, just...please. Don't think any less of me." At this point, tears were streaming down his face.

Pinkie said nothing. Her expression wasn't angry anymore, but it wasn't happy, either. Wordlessly, she hopped down from the desk, and quickly made her way out. As she got to the stairs, she heard Ace sniff, choking back his tears.

*****

Pinkie sat in her room, hugging her pet alligator close to her body. "Oh, Gummy. I feel horrible." She told him, sniffling. "I didn't expect Acey to get that upset. I mean, sure I was angry with him, but I just wanted an explanation. I didn't want him to start crying." Gummy stared blankly off, stroking his mandible across his caretaker's arm as a show of comfort. Pinkie put Gummy down, and got to her hooves. The alligator looked up at her, and blinked his eyes consecutively.

Pinkie began pacing, trying to figure out what just happened. An image made of felt appeared in her head, depicting an angry Pinkie, and a comically sobbing Ace. "And it's not as if he didn't like me anymore. I can tell that he truly cared. I heard it in his voice. He just thinks..." A realization hit her, as the image turned into a closeup of Ace's glum face. "...Oh no. He wants acceptance. He thinks that nopony can ever love him because of his interests." She gasped. "He thinks I don't love him anymore!" Tears welled up in her eyes, as her expression turned crestfallen.

Pinkie realized just how bad he felt about himself, and that in turn made her feel bad about coming off so mean. 'HOW IS THAT NORMAL?!?!' Her own words haunted her, as she came to the conclusion that those words struck him too close to home, and made him feel ashamed to be himself. Suddenly she felt more horrible than she did a minute ago. She forced her eyes closed to try to keep herself from crying, before she stamped a hoof on the ground. "No!" She exclaimed determinedly. "I can't sit around here, moping! I have to make this right! I have to show that I care, too!" She sighed, hoping it wasn't too late, that he'd forgive her for being so mean. Shaking her head, she focused on making preparations for her special show-Acey-that-I-really-do-care-about-him-and-accept-him plan.

*****

The next day, Ace busied himself by working, creating a new motherboard for a new robot. He sighed. Yesterday was an absolute disaster. He had just lost his marefriend in the worst way imaginable, and he was pretty sure some stallions dressed in white coats were coming to take him away. He felt completely awful, and now he had to weather his loss. In his distress, he snapped an important part of the motherboard off. Flinging it to the ground, he rested his face in his hands, leaning on his desk.

There was a knock on the door. Ace wiped his face, and stood. "They're heee-rrrre." He muttered to himself. Resolving to face the music, Ace stood, and made his way to the door. He opened it, holding out his wrists. "Alright, I'm ready to go." He said, solemnly.

"Good." The voice of a certain rainbow colored pony responded. Ace looked up, and saw Rainbow Dash looking at him with a smile. "Pinkie said that she wanted to meet you at Sugarcube Corner."

Ace blinked, his arms dropping to his sides. "Pinkie wants to...meet me?"

Rainbow nodded. "Uh-huh. She also said she wants to do something special with you."

This should've all sounded suspicious to Ace, but he was actually quite happy. Too happy to see this as nothing more than Pinkie forgiving him. "When does she wanna meet me?" He asked.

"An hour ago." Rainbow said, putting a hoof behind her head in embarrassment. "She sent me here immediately, but I kinda got sidetracked."

Ace gasped. "Crap, I'm late!" He exclaimed, running off. "Thanks, Rainbow!"

"No problem!" She responded, as Ace ran to Sugarcube corner.

*****
Ace stood outside Sugarcube corner, catching his breath. The more he thought about it, the more it seemed a bit suspicious that Pinkie suddenly wanted to see him, especially after yesterday. He didn't know what to expect. He opened the door, and braced for impact.

When he walked in through the door, he was immediately greeted by the pink pony bouncing in excitement.

“Yay! You’re here! You’re here!" Pinkie exclaimed, totally catching Ace off guard. "I’ve been waiting allll day!” She said, bouncing giddily.

“Sorry if I’m a little late, Pinkie. I was...thinking about yesterday.” Ace apologized.

Pinkie giggled and responded, her tone gleefully reassuring, “Oh that’s ok, you’re here now. What‘s a few more minutes. I’ve been sooooo excited thinking about all fun stuff we’re gonna do, I haven’t stopped bouncing since I woke up. I mean, I almost forgot to breathe I've been so happy.”

Ace gave a slightly uncomfortable laugh. He was sure Pinkie was still angry with him. He just couldn't shake the feeling that something was off, that she wasn't being herself. He noticed that her hair was still straight, meaning she was still not happy. But maybe, he thought, she was forcing herself to hang with him. Perhaps to remind her of why she loved him? No, that-

“So, you ready to get started, Acey? I've got everything all ready.” Pinkie announced, interrupting his train of thought.

Ace sighed, putting a smile on. “ You betcha, Pinks." He said. "Whaddya got planned?"

Pinkie beamed. “MAKING CUPCAKES!” She happily announced.

"Baking?" Ace asked. "Pinks, I'm no good at baking! You should hear about my last time trying it."

"Oh that's not a problem at all. I only need your help making them. I'll be doing most of the work." Pinkie explained.

Ace thought for about it for a second. "Well, alright, I guess that's ok. What exactly do you need me to do?"

"That's the spirit. Here you go." Pinkie handed Ace a cupcake with rainbow icing. Ace looked at it, confusion etched into his face.

"I thought I was helping you bake." Ace asked.

"You will be." Pinkie said, in a slightly sultry tone. "I made this one just for you before you got here."

Ace examined the cupcake. "So, is this like taste testing or something?"

"Sorta." Pinkie responded. Ace thought for a second. Why was he so suspicious of this development? Pinkie's never done him any harm, or held any grudges for that matter. So there was no reason to be suspicious. He shrugged, and popped it into his mouth. It wasn't all that bad, he thought. Although, there was a weird flavor in there that he couldn't quite pinpoint...

"It's good." Ace said, smiling, before swallowing the cupcake. "Okay, now what?"

"Now..." Pinkie informed him, her smile turning devious. "You take a nap."

"Ugh...wha?" Was all Ace could manage before darkness overtook him, and he fell to the ground.

*****

When Ace regained consciousness, he found himself in a dark room. The stench of blood filled his nostrils, and in the corners of the room, he saw what looked like bloody corpses of ponies. He tried to shake his head but found that the taut leather strap kept it firmly in place. He struggled to move, but the braces around his chest and limbs glued him to the upright planks. His legs were spread wide apart. He had been stripped of his clothes, and was stark naked. As he writhed, Pinkie jumped into his line of sight.

Pinkie grinned at Ace gleefully.“Goodie, you’re awake. Now we can get started.” She reached over, out of Ace's field of vision, and pulled a cart with a cloth laying over it.

"Uh, Pinks? What's going on?" Ace asked, his voice full of worry. "Why can't I move?"

“Well, duh, you’re tied down.” Pinkie chided. “That’s why you can’t move. I didn't think you needed to be told that.”

“But why?" Ace repeated. "What’s happening? I thought you said I was going to help make cupcakes.”

“You are helping." Pinkie stated ominously. "Y'see, I ran out of the special ingredient and I need you to get more.”

"Special ingredient?" Ace asked, fear beginning to overtake him. "What special ingredient?"

Pinkie giggled and responded “You, silly.” Pinkie grabbed the cloth and whipped it off the cart. The top of the tray contained various sharp medical tools and knives carefully organized and ready. There was a medicine bag and several other objects next to them.

To Ace's credit, he didn't panic. But the beads of sweat that began to form rolled over the leather strap holding his head down, and despite his current situation, Ace found himself becoming incredibly aroused. Pinkie, who had turned her attention to her cart, looked over at Ace, and smiled. "Look, Pinkie." He tried to reason. "If this is about yesterday, I'm sorry. I-I can't help myself, I have my interests-"

"Shh..." Pinkie said, walking over to Ace. "Don't worry, Acey! You'll be a part of the menu, soon!"

"Pinkie, I really am sorry!" Ace protested, as Pinkie placed the flat of her blade against his stomach. "If there's anything, anything I can do to make this up to you, I'll do it!"

Pinkie immediately stopped, and lowered her knife. "Weellll..." She said, moving up to him. She rested a hoof on his manhood, and looked up at him with a sultry smile. "If you can make me 'happy,' I might consider letting you go." Ace blinked, as Pinkie began caressing his dong. Was Pinkie...playing with him? Was this all just an act? "But if not..." She continued. Suddenly, the knife she was holding was thrust into the wood, a hair's breadth away from skewering his balls. This action shattered any belief that Ace wasn't in danger of being turned into the next confection. Pinkie's eyes met Ace's. "Got it?"

Ace didn't need any more convincing. "Yep." He chirped.

"Good." Pinkie looked back down at Ace's shaft, and continued to lightly nudge and stroke it with her hoof. The fur around her hoof grazed and tickled his penis, as the hoof itself brushed the base. The result felt strange to Ace, but also amazing. His breathing got heavier, as he kept his eyes on Pinkie, whose free hoof was now resting on the hilt of the knife as she looked up at him. Pulling her hoof away, Pinkie rested her jaw on Ace's stomach. "I think you're about ready." She told him. "But let me see how good you taste. A good baker always samples the ingredients, after all."

Pinkie moved her head down, and started rubbing her muzzle along the length of Ace's cock. She teased him several times, putting her lips on the head, causing Ace to shudder every time. However, she never actually started down the shaft, until after a lengthy pause on the tip, she muttered "S'for'hm." And in one quick motion, Pinkie engulfed his entire length.

Pinkie kissed Ace's pelvis, rolling his shaft around inside her mouth with her tongue. Her muzzle made it easy to take him, but Ace still almost reached the back of her mouth. Ace was filled with bliss as her mouth continued to touch him in the most pleasant ways possible. He enjoyed the attention he was receiving from Pinkie's mouth, but the life of cold from his balls resting on the blunt edge of a butcher knife was a constant reminder that he still wasn't in the clear. This excited him to no end. At any moment, Pinkie could just up and slash him without a moment's warning, and that fact made him greatly fear the mare who was now giving him head, and that fear was feeding his arousal. "Ugh...Pinkie..." Ace muttered. "I'm gonna cum..."

Pinkie's head slipped off Ace's cock at this, and she backed away, a sly smile on her face. "Well, we can't have that." She said breathily. "Not so soon, anyway." Pinkie stood for a moment, waiting for Ace's arousal to cool down a little, before she tugged the knife out from the wood underneath his balls. Pinkie rested the blade on Ace's scepter, and kept an eye on him, as she unstrapped Ace's arms. "You won't try to get away, will you?" She asked rhetorically. Once Ace's arms were free, Pinkie took the knife in her teeth, and made her way up the planks, until her soaking wet marehood was resting on top of him. "Hold me." She commanded through gritted teeth, her blade up to his throat. Ace moved his hands down, and took a hold of Pinkie's haunch. Grinning, Pinkie inhaled deeply, and thrust herself down onto Ace.

Pinkie seethed for breath, a tear going down her cheek, as she grew accustomed to the new experience. For the longest time, she only stayed where she was, not moving a muscle, making sure her knife was still a threat to Ace. Then, she started moving. Ace felt every inch of her tight and warm insides pressing up against him. He wanted to thrust, but Ace couldn't move because of the straps. "Oh, Pinkie..." He moaned. "This is awesome."

"Oh, you like that, huh?" Pinkie exhaled, getting a devious idea. She purposely slipped her hind leg underneath his, and kicked a lever, causing the table that Ace was strapped on to fall backwards. The sudden change shocked Ace, but Pinkie continued to bounce on top of Ace's cock, not missing a beat. The new position gave Pinkie all the control, and the experience drove Ace crazy. Pinkie was hitting all the right buttons to make Ace lusty. "Oh, jeez, Pinkie..." He cried, as he drew close again. "Please, let me cum this time."

Pinkie was drawing close to her own orgasm, and with the signal from Ace, her grin turned malicious. She took the butcher knife in her hooves, and raised it above her head, the tip threatening to run Ace through the skull. The spark of fear caused him to go off, and as he plastered Pinkie's innards, the knife was brought down, Ace shouting "Pinkie, No!" as her orgasm sent shivers up her spine.

*****

Pinkie laid on Ace's chest, sobbing quietly. "I'm sorry, Acey." She said. "I just wanted to make you happy."

Ace's hand moved, and rested on Pinkie's head. "You did a good job of that, Pinks. Don't cry."

Pinkie sniffled, looking up at Ace. "I didn't go overboard with the stab?" She asked.

"Honestly, I thought I was gonna die." Ace said, glancing at the knife, stuck in the wood right next to him. "That was frightening, and I enjoyed it a lot, but, let's not do that particular part again."

Pinkie nodded, and sighed, snuggling up to Ace. "I didn't mean to make you cry yesterday, y'know." She told him. "I've never made anypony cry, before. I felt awful."

"Don't worry about it, Pinkie." Ace replied. "I'm just glad you didn't dump me for having such a freaky fetish."

"You're not a freak, and I never wanted to dump you." Pinkie said, moving up to be with Ace at face level. "I just wanted you to think I was sexy. You've got interests that no one else likes, and I understand that. 'Kay? But if they make you happy, then I want a part in it. I'm your marefriend, after all."

That statement made Ace smile wide, and kiss Pinkie. "Sweet Celestia, I love this mare." He said, hugging her tight. As he said this, Pinkie's hair slowly began to poof back to it's normal form. However, there were a couple questions bugging Ace. "Uh, I hate to ask, but why do I smell blood?"

Pinkie giggled. "It's not real blood, silly!" She said. "I just dabbed some sodium and iron enriched flour on your upper lip. That's the REAL secret ingredient to my cupcakes. Mix it with some red seventeen, and you get fake blood!"

Ace looked at the corners. "And the corpses?" He asked.

"Old mannequins from Rarity's boutique." Pinkie replied. "I just make 'em look all creepy and gross. It helps with the atmosphere down here." Ace was about to ask something else, but Pinkie silenced him with a hoof. "Before you ask, me and Rainbow were making a movie a couple years ago down here. We're on the old set. I figured it would be the perfect scene for your fetish." She removed her hoof, and fluttered her eyelids. "Didja like it?"

"Oh hell yes!" Ace replied.

Pinkie giggled. "Then how about we make this OUR special room?" She asked, snuggling back down with Ace.

Ace sighed happily, holding Pinkie close. "Sounds like a plan." He said.
