Chapter 2: Call of the Zebra

It has been a couple of weeks since Flash came back from the Crystal Empire. He didn't tell the girls about what Cadence wanted, only that it was a personal matter that she needed help with. Since then, he's been taking care of the girls and making sure they're all right as well as their unborn foals. Twilight then told him to go visit Zecora because she asked for his assistance and that it was urgent.

Flash made his way through the Everfree Forest and to Zecora's Hut, but he could hear moaning coming from the direction of her hut. Flash could even smell a odd scent in the air, but he didn't have time process on this as the moanings were getting louder the further he got until he reached his destination. He could hear moaning coming from the other side of the door before he noticed it was crack open. His curiosity got the better of him as he looked through the crack and saw what he couldn't believe.

Zecora was shoving at least three of her fingers up her cunt while her other hand was playing with her breasts. Flash can see that her breasts were bigger than Twilight's and her friends' as well as her ass. He heard that zebras were more fit and had more exercise in their own homeland than ponies, but to see one with busty breasts and a big ass was almost mind blowing.

But what really surprised him is what she was saying through her moans. "Oohhh, Flash...take me...! Take this zebra slut...I need you...so bad...!"

Flash was shocked to hear that Zecora is fantasizing about him taking her. He has helped her out a few times in the past and had always thought she was hot in her way with the way she looked, with those stripes along her body and curves. Flash quickly shook his head and focused on why he's here before he gave the door on gentle knock. "Zecora, it's me Flash!" He called out before he heard fumbling inside as if she was trying to hide what she was doing.

The door was the quickly opened as Zecora was breathing heavily as if she was in a rush before she stood up straight and looked him in the eyes. Even with a brave face, flash could see her legs were shanking and could see streams of her juices coming down her leg from her cunt underneath the loincloth she is wearing. "Hello Flash! It's so good to see you!" Zecora exclaimed as he noticed she wasn't doing her usual rhyming that she always does.

"Good to see you too." Flash responded. "Are you feeling okay? Because you're not speaking in rhymes like you always do."

"I'm...uh...let's just say that it's the reason why I asked for you." Zecora told him as there is a blush on her face. "Please, come in. I already have refreshments prepared." Flash walked into her hut after she stepped aside and her cauldron was already filled with pinkish red potion.

The two of them sat down at a table where she had two cups of tea at the ready. After taking a sip of his tea, Flash let out a sigh and felt like he needed to know what's wrong. "Zecora, if there's anything that's bothering you, I am willing to help." He told her with a comforting smile. "Just tell me what it is that you need help with." Her ears dropped back as if she was embarrassed to tell him before she let out a sigh and looked him in the eyes.

"I-It is...heat season for zebras..." She told him as her face turned bright red. "You see...it's that time of year where zebras, both male and female go into heat. The stallion zebras' cocks become so erect that their pants are ripped apart and the mare zebras can't help but become wet... and not only that, but both genders can't think straight this time of year."

Flash was taking back by this, but was a little not surprised because of what she was doing before. "So that explains why you're not rhyming." He said before a thought just occurred to him. "But can't you just whip up a potion to help with your problem?"

"NO!" Zecora quickly explained. "Only the sperm of a staillon can help! It will help cool me down and as well as help me think stright again!" She then quickly hopped onto his lap and looked into his eyes with a pleading look. "That's why I asked Twilight and her friends if I could be fucked by you! Ever since I saw you made love with Pinkie Pie at that club, I couldn't stop thinking about me in her place! I have been having wet dreams about you fucking me so hard and getting me pregnant!" She hugged him close and her breast were pressed against his chest. "You always helped me when I ever needed it and now I need you more than ever! I love you so much and I want you to be my first!

Flash was shocked to hear that last part and he can tell that she desperately needs it. He then gave her a comforting smile before placing a hand on her cheek. "I'm always happy to help." He told her with a soft tone. "Plus, I always thought you're sexy. The way your stripes run down your body and the curves of it and your mane looks really cool. I be happy to be your first." Tears of joy ran down her cheek before she locked lips with him and wrapped her arms around his neck.

He soon kissed back as he kept one hand at her cheek while the other traveled on down her back. Both of them have their eyes closed as they were making out and moaning in their kiss. Their tongues soon wrestled for dominance as they continued and Zecora's was winning for about a few seconds before Flash's took control. He could already feel her nipples getting hard through the cloth around her breast before they pulled back and a strain of saliva were connecting their mouths.

Zecora then ripped off her top to let her busty lactating breasts bounced free. "Drink up...gets nutrients from my breast milk..." Flash complied and took her left breast into his mouth and began to drink her milk while he began to play with her right by twisting her nipple and massaging it a bit. He had his first taste of zebra milk and it tasted amazing to him that he sucked harder on her breast. "Oh yes...drink all that you desire..." She moan as she loves the feeling of him sucking her breasts. He would switch between her breasts after a few minutes of drinking hee milk before he took both nipples into his mouth and drink both at the same time.

Zecora pushed his head back and got down on her knees. She can see the round bulge in his pants as she worked to unbuckle and unzip them. She slowly pulled both his pants and underwear down before his cock was released. "Mmmm, seems the potion I made for the princesses, the girls and the queen worked to perfection." She said as she already have two hands on his cock and gently rubbing it. She then place his cock between her breasts and began to rub it with them.

"Oh fuck..." Flash moaned as his cock was getting massaged between her busty breasts. She rubbed her breasts either in sync or wildly by moving one up in the other down. She would even lick the tip of his cock as she rubbed it between her breasts. Zecora continue this actions for about a few minutes before she felt his cock throbbing between her breasts. "I...I'm going to cum..."

Zecora had a smirk on her face before she took his whole cock down her throat and sucked hard on it. Flash's eyes widen as his cock went down her throat before he unleashed his cum down it. Zecora drank up every last drop of his cum before she let it out and some of his load got on her face and breasts. "So delicious." She moaned before she stood up and removed the last bit of clothing she had and stood in front of Flash naked. “Now Flash before we continue, I need you to strip like me.” Zecora explained. “Partly because of the potion I’m brewing. It can cause our clothing to disintegrate or worse.” Flash finally got the hint and did as was asked.

A little time later, Zecora was finishing up her brew and Flash decided to ask her another question. “So Zecora. I know this out of my way to ask, but is there a reason why you choose me to be your first, other than what you witnessed with me and Pinkie Pie?”

"W-Well...it's because I truly love you." Zecora admitted with a large blush on her face. "When you were transferred here from the Crystal Empire, you helped out everypony in Ponyville. And when I am always out to get some ingredients for my brew, you always helped me out without question. I can see why Twilight has fallen for you as much as I have." Flash gave a warm smile before he pulled her in for a passionate kiss before pulling back.

"You could have just say so in the first place." Flash told her. "I'm sure Twilight and the girls won't mind having more in our herd. We care for one another all the same." Zecora smiled before taking a spoon and taking a sip of her brew. After a bit, she walked over to her bed and shook her flank at him with her tail raised and showing off her wet cunt.

“Then by all means my love, take me~” Zecora said in a calming yet lustful tone with bedroom eyes to him. “I want to be taken doggie style, make me feel free!”

"Okay, but you should brace yourself." Flash told her as he walked over to her and before starts, he gave her cunt a few licks to get a taste of her. The feeling of his tongue laughing around her cunt was already enough to make her moan. After getting in a few more licks, Flash stood up and rubbed his cock near the entrance of her cunt just to tease her. "Are you ready?"

"Mmm, yes. Take me!" Zecora exclaimed as he grabbed hold of her hips and slowly pushed his cock into her. The both of them were breathing heavily as she felt how big he is and he felt how tight she is. "S-So...b-big..." Her arms and legs trembled as her virginity was taken and her pussy was adjusting to him.

"And you're...so tight..." Flash told her as he pushed a little further into her. "Are... you a virgin...? How...come you were one...a-and you di-didn't let a zebra stallion...take you...?"

"I...I left my h-homeland before the heat season came...ah!" Zecora explained through her moans as he went deeper. "I'm gl-glad I saved it...for somepony I fallen for..." Flash leaned forward so that they were ear to ear as he pushed further inside her.

"You...are a one of a kind..." He told her before she brought her lips to his as he was all the way in. The two of them made out as he gave small thrust into her and her breasts were swinging from side to side with each thrust. Their tongues started to wrestle again as he began to speed up his thrusts and they both moaned in their kiss.

Soon his thrusts went wild as his hips plowed into her womb and he grabbed hold of her breasts. He pulled and massaged both of them as he continued to plow her so hard and rough. Each thrust into her made Zecora moan louder in their kiss. Her breasts began to lactate more each time he massaged or pulled on them. The two of them soon broke their kiss to get a breathing as his hand travel down her flank and gave it a good smack to leave a handprint.

"Yes...yes...fuck me harder!" Zecora begged with pleasure as her eyes rolled in the back of her head and she was in heaven. "Yesyesyesyesyesyesyesyes!!!" After many hours of him thrusting inside of her and the whole Hut being filled with their moans and the sounds of thighs slapping against each other, she could feel his cock throbbing inside of her and knew it is time. "Cum inside me!!"

"As you wish!" He told her as he gave a few more thrusts before ge unleashed his cum inside her womb. Zecora screamed out in pleasure as she came with him and can feel his cum filling her up. So much cum was entering her that he couldn't even pull out. The two of them laid on the bed with his cock still inside of her and drifted off to sleep.

The next morning, Flash to find himself the only one in the bed. He looked around to see of any sign of Zecora until he spotted a bottle on a small table with a note next to it. He got up and picked up the note before reading it. It was from Zecora and saying that she's back to normal and is out for a few things. It also says that she made this special cologne out of his musk this morning for the women the Mane Six have planned to have him fuck.

Flash let out a sigh before he put his clothes back on, put the cologne in his pocket before he headed home. Flash may not know who the girls have planned to fuck with him, but he'll do his best to pleasure them and make them happy no matter what.

In Spike's room, Smolder was dressed up like a princess with only bright blue leggings as Spike was dressed up like a royal night and plowing into her ass hard with his first dick while the second was ramming into her pussy. "Ooohh my knight!! You really d-don't have to do this..." She said in a fancy accent. "I...ah...don't want my curse to be passed to you..."

"No my princess..." Spike spoke up with grunts as he thrusts into her. "You placed yourself in this tower for too long...my heart belongs to you and... you deserve your freedom..." The two of them locked lips before Spike unleashed his load in both her ass and her womb.

Chapter 3: Soldier’s Workout 102

Flash is seen punching a punching bag at ponyville's local gym as he was getting his daily workout as part of his royal guard agenda. He's been taking care of Twilight and the girls for quite some time and they told him that it was okay for him to resume his agenda because they like to see their stallion stay fit. Once he was done with the punching bag, Flash took a towel and wiped off the sweat from his brow before taking a drink of water. "Okay, next up is a few lifts with the weights and then some minutes with the treadmill." He told himself before he noticed a familiar unicorn with a broken horn just walked in. "Tempest?" He asked and getting her attention.

"Flash Sentry, the lieutenant and impregnator of the princesses, Equestria six heroes, and the changeling queen." Tempest said when she saw Flash. Flash could see her eight pack abs because of her workout clothes and could see how busty her breasts are because of her tank top. Tempest walked around him and was looking like she was inspecting him.

"Anything I can help you with?" Flash asked as he felt a little off about her inspecting him like this.

"Honestly, it's nothing." Tempest said as she turned her back towards him and set her bag down on a bench. "It's none of my business anyway." She unzipped her bag and started to look through it for a bit. When she was done, she punched a wall in frustration. "Damn it! Forgot my training equipment!" Flash was a bit surprised by her sudden action before he approached her carefully and tapped her shoulder. "What do you want?"

"I just wanted to share my training equipment." He answered with a calming smile. "I can even help you with your workout." Tempest just let out a sigh and look at him with her arms crossed under her breasts.

"I guess I could use a sparring partner.” She said before she cracked her knuckles. "But a heads up, I train very hard when I was working for the Storm King. So don't expect me to go easy on you."

"That's cool." Flash responded in a calm tone. "I am a royal guard and sparring with a fellow warrior is good for both. But just out of curiosity, what kind of training do you do?"

Flash was flipped on his back on a training mat by Tempest herself as she had a smirk on her face. "Taekwondo... good to know..." Flash groan in pain a little.

‘’Not enough soldier." Tempest told him as she yanked him off the ground and took a battle stance. "You need more exercise to be Princess Twilight’s personal bodyguard.” Tempest started to throw some punches as Flash put up his arms to block each strike before she grabbed him by the arm and flipped him over again.

"Just how long have you been training?" He asked before getting up again.

"Long time." She answered as she continued to throw her punches before she did around house kick. Flash was fast enough to quickly duck under the kick and grab her by the arm before he got behind her and manage to knock her down by sweeping her legs.

"How's that for a lieutenant?" Flash asked as he had her pinned down. Tempest just gave a smirk smile before letting out a scoff.

"Even I will admit," Tempest said before she was helped up by him. "No one has ever gotten me pinned down before." She then noticed the time on the clock and saw how late it was. "Look at the time."

"Oh man, it's night already?!" Flash asked in a worried tone when he saw the clock. He then gathered his things in his gym bag after quickly wiping off the sweat off him with his towel. "I better get back home!" Just before he could run out, Tempest grabbed him by the shoulder and made him turn around.

“Not yet.” She told him. “There is one last exercise we need to do, and it requires two of us in order to reach our full potentials.”

Flash looked at her with an eyebrow raised asking. “What do you mean?” Tempest then yanked him to come with her and so he did. They reached the storage room, and the broken horned unicorn mare pointed him to go in there. Flash didn't know what she's planning, but he definitely didn't want to be forced in there by her. So Flash complied and went into the storage room as Tempest followed close behind. "So, what exactly are we doing in here?" He asked as Tempest closed the door behind her and she had a small blush on her face and she looked down.

"It's, uh... special kind of training." Tempest said as she sounded a bit nervous. "But, I got to be honest, I never done this before." Flash just smile before he place a hand on her shoulder.

"It's okay if you're nervous about it." He told her. "I won't judge you and I promise I won't tell anypony."

"Okay," Tempest let out a sign before she looked at him with determination. "First, you need to get naked." Flash was surprised she asked him to do that before he turned around and took a few steps forward and started to undress. He wondered why he needed to get on dressed for this special training and once he was done he turned around and saw her completely naked as her ass was towards him and she was putting her clothes folded neatly on the floor.

"T-Tempest..." Flash said nervously, even though he should be used to it by now considering how many times he seen the girls naked.

"Good, now we can get started." Tempest said when she saw him naked and took a combat stance. "The reason why we're naked is because this used be how soldiers prepare their bodies for both combat and produce healthy children." Flash did a double take on that last part.

"I'm sorry, it's to help prepare for combat and what?" He asked with a blush on his face.

“Okay, there is another reason why I want you for this. Because I want to have a child with you, a strong child.” Tempest admitted. “Twilight was the first friend who gave me a chance after the storm king was defeated. When I heard she got pregnant by you, I got a little jealous and well, I’ve been wanting to experience motherhood myself.”

"So this "special training" is just another wat to say you want me to have sex with you?" Flash asked as she gave a nod in response to confirm. "Well okay, but there's no need for a combat stance." Tempest raised a brow as he approached her while his cock was becoming erect. "It's clear that you don't know how it's done, so I'll show you how."

"What do you mea--" Tempest was about to ask before Flash locked lips with her. She was both shocked and surprised by his sudden action and was almost about to punch him for it before she felt two fingers going up her pussy. Tempest moaned in the kiss as she started to kiss back and enjoyed it. Flash started to kiss his way down her body as she let out a moan with each kiss. She felt his fingers leave her pussy before she felt his muzzle go in and began to look out her inner walls. "Ah...fuck..."

Flash rubbed her clit as he continued to eat out Tempest as hard as he can. "Holy fucking Celestia, I can see why Twilight, the girls, the princesses, and Chrysalis wanted to be fuck by him." Tempest thought as she moaned in pleasure. "But how good is he with his cock?" She then looked down at Flash and made him look up at him. “You know Flash, I bet you know how to fuck a princess; let alone a changling queen. But are you sure you’re ready to handle this body? A mare of pure military muscle?” She taunted by folding her arms in to back of her head while showing off.

The pegasus guard took this as a challenge and approached her. “Yeah, you may have experience in combat. But you lack in my field of battle, battle of sex.”

“Then show me Flash Sentry.” The broken-horned mare said while readying to fight. “Show me why the Equestrian royal guard recruited somepony like you. Show me you’re worth being something greater.” Flash then smirk as he took the advantage of being lower than her to knock her to the ground by grabbing her legs and sweeping them.

He then gets on top of her and rubbed his cock against her cunt before she quickly rolled him over and got on top. She then bite down on his neck as she rubbed her pussy against his cock. "I'm going to be the alpha in this one." She whispered in his ear.

"I...don't...think...so!" Flash grunted as he managed to get her off and quickly got behind her with one arm around her neck and he shoved his cock up her pussy hard well she's in the doggystyle position. She's screamed out in pleasure when she felt him enter her so deep and felt how big he is as her eyes rolled in the back of her head. Flash began to thrust his hips as hard as he could into her while he nibbled on her ear.

"You're...just...so...thick!" Tempest moaned as Flash continued to thrust into her.

"And...you're...so fucking...tight!" Flash grunted with each thrust. "You really needed this!" He then pulled her head back to pull her in for passionate kiss as he twisted her nipples. He pinched, twist, and pulled on her nipples, causing her to moan in both pain and pleasure in their kiss. Flash soon pulled her up and forced her on to a sitting chair position as he continued to thrust into her rapidly.

"Yes! Fuck me like the slut that I am!" Tempest shouted in pure pleasure as he continued to pinch and twist her nipples while penetrating her womb. Flash brought her breast up so he can suck on her nipple as he continued to thrust harder into her. He licked, sucked, and bit down on her nipple to hear the sweet sounds of her moans. "Fuck yes!! Use me however you like!"

He can clearly tell that she is loving this in every shape and form as he felt her walls grip tighter around his cock. Sweat was running down the two as they continued their little training session together and have lost track of time. Flash soon felt his cock throbbing inside her before he forced her up against a wall and continued to thrust into her as she screamed out in pleasure. Tempest then felt his cock unleash his load deep within her womb, causing her to cum with him and cover his crotch area with her love juices. After a few minutes of cumming, Flash pulled out of her and Tempest fell back into his arms.

"Whoa!" He said as he caught her. "I guess I may have overdone it bit." He then set her down gently before covering her up in a jacket from his gym bag and quickly put on his clothes before carrying her bride style. "I'm sure the girls won't mind having you around. There's plenty of room in the castle anyway." Carrying Tempest and both their gym bags out, he made his way back home after a nice day of workout.

In the castles homemade sex dungeon, Spike had his hands chained up to be raised up while his legs were chained down. His clothes were taken away and he had a ball gag around his mouth as he heard someone come in. He turned his head from the bench he is strapped down on and saw Smolder with a strap-on double dildo on. "It's time to see how well you handle this little bet." Smolder said with love and lust filled in as she put lube on both the dildos. His eyes grew wide and sweat was running down his head and body as he was very nervous about what she's about to do to him all night long.

Chapter 1: Help a wife for love

The train arrives at the Crystal Empire and Flash Sentry steps off with a few other ponies before he looks upon the vast kingdom made of crystals he was once posted at. "Long time no see." He said to himself as he got a nice view of it. He then remembers why he's here and not for a trip down memory lane. He's here because Princess Cadance has requested his help for something, only he wasn't told what that thing is. Flash took in a deep breath before he made his way towards the Crystal Empire's Castle where the guards escorted him towards a living room with a fireplace, a small table, and a couple of chairs. Those items weren't the only thing in the room as Princess Cadence herself was reading a book in that very room. "Princess Cadance, I'm here to answer your call." Flash said as he bow down to her.

"Thank you for coming," Cadance turned towards him and revealed she was wearing a form fitting white dress with her golden necklace and crown. She then gestured to a pair of seats facing each other. "Please, sit down." They moved over to the seats and sat facing one another, Cadance sitting in a manner that allowed Flash to see down her dress.

"What is this about, Princess?"

Cadance smiled at him, "I have need of your...expertise." That confused him. "You've managed to knock up not only my sister-in-law, but all her friends, the two other alicorn princesses and who knows who else." Flash was still confused, "how would you like to complete the set and knock up the last alicorn princess?"

Flash's eyes went wide, "Princess! Surely, you can't be serious."

"I'm very serious," Cadance smirked. "And please, don't call me Shirley." Flash frowned at her, as she sat back to try and show off more of her body. "What's the matter? Don't you find me attractive." Flash gulped as he remembered the many fantasies he had had of this very princess, even before Chrysalis blasted him with her spell. He hated to admit it, but Cadance had been his favourite masterbation image when he was younger.

"Of course I do. Honestly, if you were single I'd already be on you." Cadance smirked. "But you're married. And not just to anyone, but to my captain and the uncle of one of my future children. Why do you even want me to get your pregnant when you have him?"

Cadance sighed. "Believe me, I've tried." Flash raised an eyebrow at this. "Ever since Twilight and the others got pregnant, Shiny and I have been trying for a baby. But it hasn't happened."

"It will," Flash assured her.

"No, it won't. I secretly took a sample of Shining's sperm and had it tested. The chances of him impregnating me is very slim." Cadance told him before Flash frowned, "and I think I know why. In Shining's first year in the guard, he received an injury to his groin. It had him laid out for weeks, but it seemed to have had another effect."

"I see," Flash sighed. "Have you told Shining about this?"

"Of course not," Cadance shook his head. "Shining's always been Insecure about his manhood. If he found out he was infertile, I fear the shame my make him suicidal. And if I don't get pregnant soon, he might decide to test himself and discover it himself. That's why, I need your help."

Flash sat back and let this information sink in. Honestly, he could understand what Cadance was thinking. He had already proven more then once how good he was at repopulating the species. Her plan was a good one. She and Shining would have the child they want, Shining wouldn't need to know about his inability to breed and Flash would get to have a night of passion with his teenage crush. Everypony would win. However...

"I'm sorry princess," he stood up. "I understand where you're coming from, but I can't do this to the captain. If I did, your child would think it's mine's cousin. They'd always been playing together and I'd have to see Shining make a fool of himself thinking he's raising his own child. I respect him too much to let that happen."

Cadance sighed, but smiled. "You don't have to worry about that. I've already taken precautions to make sure the child is Shining's." This confused Flash, as a knock at the door caught their attention.

Cadance stepped over to it and opened it up to show a Crystal Unicorn mare. "Good evening, princess."

"Hello Ruby," Cadance smiled. "Do you have what I asked for?" The pony nodded and held up a bottle of silver liquid.

"I managed to get the hairs like you asked for and added them to the potion before the captain left." Cadance nodded and took the bottle, thanking the mare before closing the door and moving back over to Flash.

"What is that?" Flash asked, as Cadance stood over him.

"A potion I asked Zecora to make. If somepony drinks it, it'll temporarily rewrite their reproductive material to match that of whoever's DNA is mixed with the potion. I'm guessing you know whose DNA is inside it."

Flash took the potion and looked it over, "Shining's."

"Exactly. Drink that and for twelve hours, any child you father will be Shining's instead of yours. Don't think of what you're doing as betraying my husband. Think of it like...tagging in for him in a sport. The guards are all about working together towards a common goal. I'm sure if the roles were reversed, Shining would be willing to do it for your." She stepped away from him and walked towards another room. "My husband is out on an exercise and won't be back with his troops until tomorrow afternoon. That gives us all night to make a child before he gets back." She turned to smile at him, "still don't wanna do it?"

Flash thought it over and he knew this was wrong to take another's wife, but both Twilight devastated to find out she won't become an aunt. Not only that, Shining Armor would blame himself to find out he won't ever give Cadance a child. Flash let out a sigh before he gave an answer. "Okay, I'll do it your highness." Cadance smile as she handed him the potion before headed towards the door. "Let's go to your bedroom and we can get started." She smiled as she followed him out the door and to her bedroom.

Flash drink up the potent and was waiting for Cadance to come out of the bathroom because she said she wanted to change into something before they start. As he waited, Flash looked over himself and he wasn't any different. "Maybe the change is on the inside?" He wondered as he still felt a little uncomfortable about this. A part of him felt it was taboo to fuck another stallion's wife in the same bed they shared. He even thought his coat would turn white and had another thought that maybe Zecora's potion didn't work.

Cadance finally stepped out and Flash was greeted to the sight of her in a light blue silk nightgown. It was sheer, allowing him to see almost everything beneath it.

As he sat on the bed, he felt his pants growing tighter as Cadance got closer. As she did, she slowly and sensually began to undo the belt and slid it out of the gown. She threw it at Flash and he grabbed it, feeling the softness of the fabric as his imagination went into overdrive and he suddenly found himself picturing Cadance tied to the bed with this belt and helpless against whatever Flash chose to do to her.

Cadance then slowly slipped the gown off, first revealing her shoulders before letting it slide down her body to reveal what was underneath. And what she was wearing almost had Flash blowing his load right then and there.

She was wearing a three-piece lingerie set, which was almost completely transparent with the exception of the straps. It was the same light blue as her nightgown, matching her cutie mark beautiful. Her bra was holding up her large breasts and allowed Flash to see her dark pink nipples through the fabric, which were already starting to go hard and poke out. She was wearing a frilly garter belt around her beautiful hourglass waist, which had straps connecting to thigh-high stockings that stopped just below her cutie mark. Finally, she was wearing a pair of light blue panties that completed the image and made her look like something out of heaven itself.

"P-Princess... you look amazing." Flash told her in a nervous tone as his face was red as a tomato.

"Please Flash, call me Cadance." She told him as she got on his lap. "No change? Must be on the inside." He can tell that her tone was seducive as she started to kiss along his neck. Flash groan as she help them remove his jacket before she slowly took off his shirt and tank top to reveal his bare chest and muscular abs. "Just like his~." She then started to kiss his abs as her hands started to unbuckle his belt and unbutton his pants. After she pulled down his pants and underwear, she gasped in surprise when she got a good look of his cock. It was still 20 in long from the time he fucked the main six, the royal sisters, and Queen Chrysalis. "How did Twilight and her friends let you come here with this monster?!"

"Well, it's a long story." Flash told her as he rubbed the back of his head with a small blush. Cadance couldn't take her eyes off his cock as he looked bigger than Shining. She licked her lips before she began to lick his cock from the base to the tip. She then leaned forwards and gave the tip a quick kiss, getting a moan from Flash, then started licking it like it was the last popsicle in the freezer. "Oh fuck...Shining is a very lucky stallion." He moaned at her tongue skills.

"I'm glad you love it~." Cadance said before she pushed him on his back and put her cunt with very wet panties over his face. "But don't expect me to do all the work~." He smiled before he grabbed hold of her panties and slowly pulled them down to reveal her soaking wet cunt. Flash didn't want to disappoint her, so he took his muzzle deep within her cunt and lick every inch of her walls. "Aaahh~!!" She cried out when he began to eat her out.

Cadance then surprised him by sticking his whole cock down her throat. Flash moaned inside her cunt as she was able to deep throat him with ease before he continued to eat her out. The two of them were like this for what seems to be hours to them before she felt his cock throbbing in her throat. She didn't even slow down as she deep throated before with Shining Armor and wants to see if she can handle him when he cums. Flash soon unleashed his cum down her throat just as she came all over his muzzle. Cadance was drinking loads of his cum as she felt her lungs burn from the lack of oxygen but was not going to let his cock out of her mouth till she drink up every last drop.

Once his cock stopped, she let it out with a loud pop from her mouth before to her surprise, Flash quickly got her on her back to lay on the bed before he grabbed her bra and took it off with one pull. He then latched on to her right nipple while he played with her left breast by squeezing or pinching her nipple. Cadance let out a lustful moan as he was enjoying her breast as she felt his cock poke her below. She held his head close as he continued to suck on her milk before he quickly locked lips with her.

Cadance was surprised by his action before she quickly kissed back and tongue wrestled while they moan. She hugged him tight before he aimed his cock towards her cunt and gave one powerful thrust into her that caused her to moan so loud. "Fuck! You're...so...tight..." Flash grunted as he humps her. Cadance wrapped her legs around his waist as he thrusts into her rapidly.

"Oh Celestia!! Don't stop~!!" She told him as she brought her list up to his again and started making out while he thrust into her. Flash picked her up and continued to thrust into her rapidly while they make out. Flash then had her top half lay on her back while he thrusts into her harder. He didn't slow down as he pound into her even harder while he holds her legs up. Sounds of her moans and her flank being slapped with each thrust filled the room as she was enjoying his cock.

After almost thirty minutes of their constant pounding, and three orgasm for Cadance, the pair finally felt themselves hit their peak and they climaxed together. Cadance cried out and was glad she had soundproofed the room. That was the last thought before the mixture of pleasure and exhaustion overcame her and she blacked out.

Cadance's dreams was one she had had many times, of a great knight coming to free her from an evil villain and claiming her. But instead of her husband, who had always been the star of her wet dreams, it was Flash that burst into her tower room and took her.

This dream made her moan and as she faded out of it, she became more aware of her real body and realised her arms were up by the headboard and bond to it by something soft.

And as she became more aware, she realised something was touching her. A pair of lips were slowly travelling up her stocking clad legs. And when she opened her eyes, she saw Flash was awake and doing just that.

Her movement made Flash aware of her awakening. He looked up at her and smiled, Cadance smiling back as an idea popped into her mind. Shining didn't enjoy roleplay, but maybe he did.

"Oh," she moaned, "Who are you? What are you doing here? Why am I tied to the bed?"

Flash seemed to instantly realise what she was getting at and started playing along. "You've been teasing me and the rest of the guards for too long. Your husband kicked me out of the force when he caught me checking out your sweet ass. Now I'm gonna get what I lost my job over."

Cadance pretended to gasp, "Please no. I can't be untrue to my husband."

"Oh, you'll soon change your tune." He said before he ground hold of her hips and begin to thrust into her. Cadance couldn't help but let out a loud moan as he thrust into her really rough. Flash then leaned forward and nibbled on her neck as he continued to thrust. "Ah! I bet your husband never fuck you like this before~?!" He asked before giving her breasts a few good smacks.

"Ah! N-No he...ah!..ne-never did!" Cadance answered through her moans of both pain and pleasure. Flash was only getting rougher as he pinched both her nipples and pulled on them hard. Her eyes rolled in the back of her head as he continues to plow her. "Pl-Please...don't...aahhh...stop~!!"

"So, you love how I fuck you better than your husband?" Flash asked as he slapped her flank hard to leave a handprint where her cutie mark is while he thrusts into her more.

"Much better~!!" Cadance shouted as her tongue started to hang out of her mouth. "He never gave me this much pleasure before!! Fuck me harder~!!" Flash granted her wish as he thrust into her even more while he sucked on her breasts. The wet sounds of his thrust mixed in with her moans filled the room as he took her.

"I-If you want me to c-cum in you, call me your master and say you're the princess of lust!!" Flash told her as she felt his cock throbbing in her womb.

"Please!! Pl-Please master, c-cum inside the princess of lust!! I'm your princess of lust~!!" Cadance begged. Flash smiled before unleashing his cum into her womb yet again and bloated her belly even more. The fun didn't end there, however. As after only an hour's rest, Flash was ready for another go. He untied Cadance and the pair were at it once again, with Flash lifting them into the air and performing a technique he and Rainbow perfected.

He flew up with Cadance on his cock and stopped mid air, allowing Cadance to almost fly off his dick until gravity stopped her right at the tip and pulled her down onto him hard and fast. They did this several times and Cadance was in heaven.

She had a feeling that potion had an added benefit, allowing Flash quick recovery. It only took him a little bit of rest after that event to be at it again, then again and again. All throughout the night, the pair were at it like rabbits and Flash's balls never seemed to empty.

Her belly bloated from the amount of cum getting poured into her and impregnating her. Once they finally stopped, after what was probably their tenth go, Flash was resting on her as his cock was still inside her. Cadance never felt so much pleasure before, even when Shining Armor took her in bed. She smiled as she cuddled him close and the two of them fell to sleep.

The next morning, the two of them were still asleep until Flash woke up and remember what happened last night. He gently pulled out of Cadance before hitting the shower. After a few minutes, Cadance slowly woke up to find Flash putting on his clothes and looked ready to head out. "Leaving already?" She asked him.

"So sorry your highness, but I'm a little concerned with Twilight and the others." Flash told her. "What if they need me and the babies are coming? I want to be there for them and well--" He was silenced when she used her magic to keep his mouth shut. Flash looked at her and saw that she had a warm smile on her face.

"It's okay Flash, I understand." She told him. "And you can call me Cadance. Just have yourself some breakfast before you leave and tell Twilight I said hi and I'm proud of her, along with her friends." Flash smiled before he took the handle of the door. "And one more. For what it's worth, I think you make a good father and a great husband to them. You really convinced me last night." Flash chuckled a little before he gave a smile back to her.

"Thank you, and I hope you give birth to a great kid." Flash told her before he opened the door and went on his way. Once Flash was gone, Cadance sighed as she let herself continue to lay upon the bed.

She could still feel the enormous amount of cum flowing through her body, trying to get out. But she wouldn't let it. She grabbed a pillow and pushed it under her, keeping her body folded so her cunt remained pointed to the ceiling and the cum pooled down into her womb. As she patted her slightly swollen belly, she realised Flash had probably shot more cum inside then in one night then Shining had throughout their entire relationship.

A knock on the door caught her attention and she pulled her blanket over her body, "yes?"

"Princess," it was Ruby, "can I come in?"

"Of course," Cadance nodded as Ruby stepped into the room. The crystal unicorn looked her over and smiled.

"I can see you've had quite the fun night."

"It was wonderful," Cadance told her. "And hopefully, it will lead to the results I'm hoping for."

"So do I, princess. So do it."

Cadance nodded. "Thank you again, for getting the hairs I needed. If you hadn't, Flash never would have agreed to it." Ruby nodded as Cadance's curiosity got the better of her. "So, what did Shining do when you got the hairs. Did he flinch or anything?"

"No. He was too busy marching towards the border with his troops. None of them would notice a few hairs flying off of him. A quick snip with magic and they were mine."

Cadance nodded, then heard what she said as her eyes went wide. "Snip. You cut the hairs off him?" Ruby nodded, looking confused.

"That's what you told me to do. Get a few hairs and put them in the potion."

"But I didn't mean cut them off. I needed you to pull them out, hair follicle included."

"Why? He would have noticed if I did that." Cadance wanted to yell at her, but realised she wouldn't know. She and the rest of the Crystal Ponies were from a time before science really advanced. They wouldn't know hair itself didn't have any DNA. But this meant the potion hadn't had any DNA to rewrite Flash's genes with. That meant...Flash had been shooting his own loads into her all night.

Cadance removed the blanket and looked down at her stomach, now realising that it could possibly be growing Flash's child within it instead of her husband's. She wanted to be scared, but for some reason she was actually kind of...happy. She didn't know why, but the thought of having Flash's child alongside the rest of the alicorn princesses just felt right to her.

She sighed, a smile appearing on her lips. There was a chance she hadn't been impregnated, but she knew in her heart she was. She was going to have Flash's baby and that was alright with her. Though a part of her also wondered if she could convince Flash to give her a second baby later on, then a third, forth and maybe fifth.

Back in Ponyville, within the castle of friendship, Applejack and Fluttershy had finally come up with one or two mares for Flash to have fun with. Fluttershy thought that Dr. Fauna and Zecora for Flash to fuck and Applejack thinks her old friend Rara would be perfect. Twilight caring a list of mares for Flash as she walked down a hallway before she stopped and heard moaning coming from the room with the pool. She open the door and saw Spike on top of Smolder as he was thrusting into her cunt. "Oh fuck Spike, take me harder~!" Smolder mona as he slapped her ass.

"Celestia, I love how hot and tight you are Smolder~!" Spike told her as he continue to thrust into her on the edge of the pool. The two of them were so focused on their little fuck session, that they didn't notice a flash from a camera flash on them. Twilight quickly close the door with a camera in her hands as she looked at the picture of her son and his mate.

"I'm so proud of you, Spike." Twilight said as she continued her way down the hall and couldn't wait for Flash to get home.
