>Bon-Bon was really nervous.
>She never had been with a stallion before.
>It was never something she wanted.
>But, the cravings... it really screws with your mind.
>Bon-Bon had been eyeing a certain red-bodied and strong stallion with a apple cutie mark, whether he was at the market or anywhere near.
>Ever since she got inseminated from the clinic, ever since she was told it was his sperm. Her infatuation grew like her big belly did.
>Now eight months pregnant, the colt inside her was lively.
>She remembered the way to Apple Acres ever since she went with Lyra to drink apple cider.
>It was dark and perfect for sneaking.
>Bon-Bon had to meet with him, to satisfy herself and her crazy instinctive heat.
>Past the barn with a bag, lockpicking the door to the western home, tip-toe through the kitchen, up the stairs as silent as a mouse.
>Now to look through the keyholes.
>First door on her left was a little filly, she was sleeping soundly mumbling something about cutie marks.
>She trotted silently and looked through another keyhole to find her prize.
>He was sleeping on his back, in his room there wasn't much to look at except family member pictures and cabinets for clothes and such.
>Bon-Bon turned the knob on the door, it screeched a bit, yet she opened just enough for it to not be too loud.
>She neared him, making not a sound, she eyed him, so asleep and father to her colt.
>The heat was so unbearable, but she regained her calm.
>From her side-bag, she pulled out a needle, it contained an aphrodisiac that would make stallions wild.
>She quickly injected the tiny needle into his neck, it caused his member to erect while he slept.
>Seeing the bedcovers heighten, Bon-Bon could not resist it any longer.
>She ripped off the covers and awoke the sleeping stallion.
>Pinning him down, she smacked her mouth right into his, while she felt the erect phallus on her ass.
>Big Macintosh's eyes where wide with surprise, then the injection took full affect on him.

>Big Macintosh, with new ferocity and unyielding sexual aggressiveness, pushed Bon-Bon on her back to the bed.
>She yelped quietly as she saw the crazed stallion drool on top of her, eyes filled with animalistic fury.
>Bon-Bon was scared, what had she gotten herself into, she would ask herself.
>All the regret and fear, all the nervousness just melted away when she felt that penetration.
>It was quick and powerful, expected from a strong stallion of Big Macintosh's caliber.
>It stung her in a good way, the friction of his member sloshed aggressively with her insides.
>She tried her best to keep the moaning at bay, but the pumping was too much.
>Big Macintosh groaned repeatedly, breathing heavily and quickly with each pump.
>As the pressure became unbearable and felt incredibly good, Bon-Bon was about to scream loudly.
>With a plan in hoof, she pressed her mouth into his and moaned with a kiss.
>With a powerful thrust, he hit deep inside her and let loose his seed with locked lips.
>She groaned with each spurt, her vaginal walls tightening around him, sucking each drop.
>Bon-Bon released her kiss and lay on the bed exhausted.
>Big Macintosh lay on her pregnant belly softly, like a pillow.
>He could hear the heart beat inside her stomach, the furtive life within.
>He slept soundly on his own sons home.
>Suddenly, a light-turned on and there was a surprised Applejack just watching them both.
>Bon-Bon looked at her with those eyes filled with surprise and felt a feeling of gratification.
>The little filly from next door trotted to see what was going on.
>"Applejack, whats going o-"
>"Go back to bed."
>"But, Applejack!"
>"I said go back to bed! Now!"
>Applebloom trotted back to her room, waiting for whatever might have happened.
>Applejack walked towards the bed in a menacing manner.
>Bon-Bon said nothing, she only breathed, her cheeks red like fresh cherries.
>Applejack smacked him in the head awake, he clumsily got up from Bon-Bon's pregnant belly.

>Big Macintosh got out of the bed with the weak Bon-Bon and her eyes filled with tired haze.
>He pulled out his member with confusion as his tip spilled drops of after-cum on to the roughed-up bed.
>Applejack scrunched her face and trotted out of the room, she turned towards Big Macintosh with an angry glare.
>Big Mac trotted his way to meet up with his sister.
>Applejack closed the door, leaving Bon-Bon to close her eyes and rest.
>He stared into his sisters eyes with fear.
>"Why? Why did you do this Big Mac? We have a beautiful daughter together and you had to sleep with some hussy!?" whispered Applejack.
>Big Macintosh looked away with guilt.
>"What about Applebloom!? Have you forgotten that she is your own daughter!?"
>"I... I haven't forgotten, it's jus', I don't know what came over me. I couldn't control myself."
>"That still doesn't explain her big belly!"
>"Applejack, I don't know if thats mine or not! I haven't slept with another mare other than you and with protection."
>"I don't know if your sincere or not, but I know that you have to be punished, seeing that mare with that belly is making me right jealous..."
>"What are you suggestin!?" whispered Big Macintosh.
>"Mac, I want another one, we can just make up some excuse! It will be fine."
>"I dunno, ya sure bout this?"
>Applejack didn't give him an answer, she only trotted past him while caressing him with her tail, looking at him back with bedroom eyes.
>He gulped and followed her.
>After a while, Bon-Bon awoke from her orgasmic fever. She got up from the bed and touched her belly, feeling the unbearable heat was finally gone.
>She trotted out of the room, making her way down the home.
>She exited through the door that she entered with, it was a dark morning and she had to get back home before Lyra became suspicious.
>Bon-Bon stopped, hollering was being heard in the red structure to her left.
>Curiosity enveloped her, she went her way and poked her head in the red farm house.

>Bon-Bon watched enchantingly as the two went all out.
>Big Mac smashed his pelvis into her sister with all the love he felt.
>Applejack was screaming with pleasure, her face was so orgasmic.
>Mac, eyes squinting, teeth grinding, thighs pushing, body tensing, and sweat pouring down.
>Jack, pussy enveloping, body pushing to get that meat as much in her as possible, fierce grinding against each other, both parties relishing the sex.
>Bon-Bon was enchanted beyond belief, it was so hot that she began pressing herself into her mare-hood.
>Her pussy watering with each push on her pussy.
>The three relishing the incredible stimulation.
>Then, Big Mac put out, leaving Applejack to lose footing and drop her hat.
>Applejack screamed a high-pitched scream as her womb was splashed with a wave of Big Mac's semen.
>She coughed at the intensity and fell on her face, dizzied out by the intense orgasm.
>Big Macintosh's penis slid off as she fell to the ground, cum pouring on her.
>He stood on two hoofs for a few seconds before losing footing.
>He fell on top of his mate after losing consciousness.
>Bon-Bon was just about finished, she climaxed and made a tiny puddle of liquid under her.
>She started breathing, feeling the climax as she remembers Big Mac's powerful cock.
>She trotted away back to Ponyville, through the market place, through Sugar Cube Corner.
>Made it to her home that she shared with Lyra.
>Entered the door, went to the bed and shook the green-minted unicorn awake.
>"Bon-Bon? What is it..." said Lyra lazily.
>"Lyra, I have something to tell you."
>"Can't it wait later?"
>"Lyra, I'm leaving you."

>"What!?"
>Lyra rose from her bed in shock.
>"I'm sorry Lyra, but I can't be with you anymore, I must have... him!"
>"Who?"
>"Big Mac! You see Lyra, I was in heat and no matter how much you and I had sex, it just wasn't enough."
>"I was disgusted, but I craved it, Lyra, I craved that abominable organ from a male, I'm not a lesbian... not anymore."
>Lyra stood from her bed with confidence.
>"Fine, show me this stallion you fell for, at least let me try 'em out."
>"What!?"
>"I may be a lesbian, but I can experiment sometimes."
>Lyra got out of bed, Bon-Bon was filled with worry.
>"Hmmph, alright Lyra, follow me." said Bon-Bon with a smile.
>They both exited the home and went there way while the morning sun shone brightly above them.
>They arrived at Sweet Apple Acres and Bon-Bon personally knocked on the door.
>The hinges screeched and a hatless Applejack trotted outside.
>"You! Get out of here before I get my dog you succubus!."
>"Please! If you do that than I might spill the beans on your 'relationship' with your brother." said Bon-Bon.
>Applejack grew furious, but was only met with a smirk from Bon-Bon.
>"Sigh... Whatta you want?" said Applejack defeated.
>"My friend here wants to sample your merchandise."
>Lyra looked up from the ground in embarrassment.
>"No! He's mine! He's not to be passed arou-"
>Bon-Bon only smirked again and it gave Applejack a feeling of dread.
>"Ugh... fine, but this will be our little secret, ya hear!"
>Applejack let them both in and they followed her upstairs until they made it to Big Mac's room.
>"Wait, here." said Applejack to the two.
>She trotted and whispered a few things into his ear as he lay on the bed.
>He got out of bed and Big Macintosh trotted his way to meet with his partner.
>"Make it right quick!" said Applejack as she trotted to her room.
>Lyra frowned nervously at the towering behemoth before him.
>"Eeyup, right this way missus."
>Lyra followed him and they both sat on the bed.

>Lyra looked around the room, Big Mac only stared awkwardly at her.
>"Oh for Pete's sakes!" said Bon-Bon.
>She went to the bed and spread Lyra's legs for Big Mac to go in.
>Lyra screamed "Wait!" over and over again before she got penetrated.
>There was no stopping it now, Big Mac began groping and thrusting into her in ten seconds flat.
>Lyra was in shock, she has had it with men before, but never felt this good.
>It felt like she actually wanted the cock.
>She also moaned, just like that! Lyra was amazed while she got pounded.
>Big Mac went in and landed a kiss on the surprised Lyra, then closed her eyes and went with it.
>Lyra felt unlike herself, suddenly, womanly urges started to overwhelm her. Gone was her Lesbian deep voice.
>She screamed like a helpless and confused, but orgasmic slut.
>Then, Big Mac fired his load deep in her, his seed spreading all the way inside.
>Big Mac got off of her and released his member from her snatch.
>He lay on his bed looking at the ceiling tiredly.
>Lyra was knocked out almost completely, with a trail of saliva dropping from her mouth.
>Bon-Bon looked at Lyra with pride, she had just gotten penetrated beyond belief.
>"Heh, you'll be pregnant in no time you cock hungry slut." said Bon-Bon.
>She trotted to the bed and lay on her back next to Big Macintosh and just watched her fallen compatriot slumber away.
>"I'm back from school!"
>The screech of the door spelled doom, and Applejack hurriedly got up from her slumber and ran to Big Mac's door before she had a chance to see what was going on.
>"Applejack? Whats going on? Why are you covering the door to Big Mac's room?"
>"Uh... he is kinda busy, Sugar Cube... heh, just go on to yer room and give him some privacy ok?"
>"Uh, well whatever you say, Big Sis!"
>Applebloom trotted to her room.
>Applejack gave a breath of relief and went inside the room.
>She went to the bed and told the two to wake up.
>They snuck out under Appleblooms noses and left on their way to home.
