Love Poison +

It was that one time in the early year again, when it was truly meant to spend time with your loved one. The one you considered a girlfriend or wife at the time, hoping to stay with her forever and ever. Hearts and Hooves day in Anthroville. Every year Hearts and Hooves day showed off the many couples that lived here, as well as show the loneliest. As usual, the Cutie Mark Crusaders didn’t have anyone to spend their time with. As they were too busy trying to get their Cutie Mark still. It still feels like they tried everything but they never gave up hope, for one day they will find it.

“Oh I know, how about we try matchmaking again?” Scootaloo spoke up

“We tried that last year and didn’t work out so well.” Sweetie Belle complained.

“Yea I know, but what if the pairing wasn’t right? Maybe Big Mac and Cheerilee aren’t meant for each other; maybe Big Mac should be with someone else.” Scootaloo didn’t want to give up on the chance.

Applebloom finally spoke up. “She has a point ya know. Maybe my brother is suppose to be with someone else.” She put on a thoughtful look. “Hey why does it got to be mah brother anyways?”

Scootaloo laughed nervously. “Heheh well, I was thinking we could put him with Rainbow Dash. She isn’t hanging out with anyone, says they’ll slow her down. But I can just imagine Rainbow and Big Mac together.”

Sweetie Belle wasn’t convinced. “What makes you think they would go so well together? Big Mac is an earth pony; he’ll be grounded all the time.”

“Don’t worry about that, let’s just make the potion and we can see what happens, Applebloom can make a mean potion still I bet.”

“I suppose I could, but I’ll need to see the recipe again to make sure.” Applebloom thought of where they can get it. “We should check with Twilight as usual.”

The three got off the floor and exited their clubhouse. “CUTIE MARK MATCH MAKING CRUSADERS GO!” They all screamed as they ran into town. The town was covered in pink. Seems like Pinkie Pie might have done the decoration, but that wasn’t true. Throughout town the fillies can see all kinds of couples. Bon Bon and Lyra, Doctor Whooves, and Derpy, and many others.
“I really hope your right Scootaloo, it’ll make me sad if they aren’t meant for each other.” Sweetie Belle said, always one to love sappy moments.

“It’ll be easy, we make the potion, get them to drink it somehow and bam we get our cutie marks.” Scootaloo said confidently.
After a while of walking they finally made it to Twilight’s library tree house. They knocked on the door hoping Twilight was home. Inside they can hear Twilight talking to someone it sounds like. “Shoo be quiet Fluttershy, they can probably hear us. Just go to my room, I’ll be back.” The last sentence with a hint of seduction. Soon enough the door opened to Twilight’s magic. “Hello girls, you three didn’t hear anything right?”

The girls decided to play it safe and shook their heads no. “We were uhh just here for a book.” Applebloom started.

“You girls aren’t planning to make Big Mac and Cheerilee fall in love again are you?” Twilight accused.

“What again? No we learned our lesson last year.” Scootaloo said innocently.

“It’s even better this year, it’s going to be-“ Sweetie Belle stopped as the other two put their hands over her mouth.

“Heheh see, nothing.” Applebloom knew Sweetie Belle was probably going to mess them up.

“Alright fine girls, don’t do anything crazy, I’ll be in my room if you need me.” With that Twilight left the door open for the girls and went up into her room. The girls quickly moved in looking for the book. Looking up and down anywhere for the book.

After a while of searching, Applebloom spoke up. “I found it.” She raised it up for the others to see it. She set the book down on a table and began to read it. “Love poison +? That’s new to me girls. Let me read it. “This is an improved version of the Love Poison, the + means the love~~rs~~ will grow more and more over time.” My gosh this potion is awesome, not only will they fall in love, but the more in love they are the stronger it gets, this will surely get our Cutie Marks now.”

“I don’t know, “rs” has a line through it for some reason.” Sweetie Belle pointed out.

“It’s a typo silly; they clearly meant to say “Love” why would “Lovers” grow? That sounds dumb to me.” Scootaloo said with a matter of factness in it.

“Scoots does have a point Sweetie Belle, maybe your just overthinking it a bit? Now come on, we got to make this potion quick.” Applebloom closed the book and ran out with the other two girls behind.

After having found the needed ingredients, Applebloom was able to create the potion. “Hmm it sure does look different from the last one.” Applebloom noted outloud.

“Well duhh, it is a different potion, of course it’s going to look different, why would it look the same? Now come on, it’s already late in the morning we gotta deliver this soon.” Scootaloo rushed out the house with potion in hand to where hopefully Big Mac and Rainbow Dash would be waiting for them.

In the Apple Family farm, Big Mac was walking around trying to find some kind of rat that Applebloom claimed to have seen. Applebloom said it was a big rat, hard to miss too, but Big Mac just couldn’t see it, was his little sis lying to him again? Soon enough he heard wings flapping outside and a feminine voice call out.

“Scootaloo you in there?” It sounded like Rainbow Dash, why would Scootaloo want her here? “I’m here to see the new exercise you got set up.” Rainbow Dash started to walk inside the barn. Upon entering she could see Big Mac. “Oh hey Big Mac didn’t know you were here sorry.” A slight blush appeared.

“Eeeyup, no worry. Just helping my sister.” Big Mac didn’t seemed bothered seeing Dash come in, even though his shirt was off. Big Mac was just about to give up when he heard his sister’s voice and her friends.

Soon the trio came crashing in next to Rainbow Dash. Scootaloo spoke up first seeing her role model. “Oh Rainbow Dash you’re here early, that’s great. I hope I wasn’t keeping you waiting for too long.” Scootaloo said trying to think of something.

Applebloom spoke up next. “Hey big brother. Mind testing out a drink we made? Zecora says it helps one’s body relax or something. Since you and Dash like to work out a lot, maybe you two can try it out.” Applebloom looked at Big Mac with puppy eyes hoping to make them accept the potion.

Scootaloo did the same thing to her idol. “Please Dash, we’re hoping to get out cutie marks.” Both Dash and Big Mac look at each other wondering whether to accept or not.

Finally Rainbow spoke up. “Alright fine, I guess we can try it, but nothing weird better happen, I need to keep in good shape you know.” She pointed at her body to indicate how she wanted to stay fit. “Alright so let’s try it then.”

The Cutie Mark Crusaders cheered ready to see the results. Sweetie Belle gave both Dash and Mac a vial filled with the love poison +. “Drink up, and you’ll uhh…start feeling better in no time.” She looks over at Scootaloo and Applebloom and winks at them for having saved herself. They weren’t sure what to think about it.

Soon the two began to gulp down the vial, waiting for the results. In no time both Dash and Mac did seem to relax. “Hmm this potion you two made seems to work well, wouldn’t you agree Big Mac?” She looks over at him.

He nods his head and replies with his usual “Eeeyup.” and looked over at her. That’s when the girls knew that their potion has taken effect. “Well howdy there Miss Dash, you sure look lovely today.” Both their eyes turned pink indicating the Love poison +.

“Oh thank you Big Mac.” Dash blushed, “It’s nothing really, I should have dressed better for the occasion.” They both moved in close and gave each other a hug. “I love you Big Mac.”

“I love you too Dash.” The two continued to look each other in the eyes embracing each other in their touch.

Scootaloo cheered. “Yes I knew we could do it, I told you it would work. Look how much they love each other.”

Applebloom whistled seeing the results. “I suppose you were right Scootaloo, well I’m glad this worked out well enough.”

“Umm girls, I think something is wrong, I’m hearing rips for some reason.” Sweetie Belle said. “That shouldn’t be happening I think.”

“Oh relax, what can the ripping sound possibly be? It’s not like their ripping their clothes to have sex, we’re too young to see that.”

“Yet you know about it Scootaloo?”

“Umm yea, Dash taught me a few things, she like the only family I have, someone has to teach me.” The girls stopped paying attention to the ripping noise as they argued between each other about sex and how it works. Unbeknownst to them, the ripping sound did come from the two lovers but for a different reason.

The two lover’s eyes focused on each other never moving, their ears only listening to what the other had to say. “Oh Big Mac, why didn’t I notice you before? You’re handsome, strong, quiet, and handsome.” Rainbow Dash said, not paying attention to the trio of girls, or her shirt for that mattered. The more she spoke the tighter her shirt seemed to have gotten. What use to be a flat chest was rapidly forming breasts underneath her shirt.

“It’s okay Dash, I’ve always admired you from a far, but my sister wouldn’t let me, but now we should take the chance.” Big Mac as well was experiencing a similar development but instead of her chest, it was closer to his legs. His pants and boxers were having a hard time trying to contain his member that seemed to grow underneath.

The Cutie Mark Crusader had no idea what was going on, but neither did the lovers as all they did was talk to each other. Soon enough the rest of the clothing on the lovers began to tighten as well.

“Eww they almost sound like last year with Cheerliee, you sure this was a good idea?” Scootaloo complained.

“What? This was your idea Scootaloo, what do you mean we were sure this was a good idea?” Applebloom protested.

“Well you two could have said no to my idea and this wouldn’t have happened; now we have to listen to them.” Scootaloo pointed at the two lovers, who were inching ever higher. Soon the two were at eight feet each, their clothes barely holding on to them.

“So how are you feeling Big Mac? Nice and heavy I hope.” Rainbow Dash took notice of the ever increasing bulge that was hiding from her. “You know I love you, and you love me.” She whispered in his ear.

“I love you too Dash. And I sure am thirsty for some milk.” As he stared at her chest, her expanding breasts hardly contained by her now small bra.

As the two kept exchanging words with each other it seems to only fuel the growth, faster and faster they grew, already passing ten, eleven, twelve feet, they grew on and on. While the three girls continued to argue among each other ignoring the older anthros growing in the barn.

Finally at twenty feet did the last remainder of their clothes decide to give out. Rainbow’s bra popped off her now G-cup jugs, and her panty snapping off as well, showing her bubble butt, and soaking sex. Big Mac had an easier time as his member ripped his boxer in the middle, now showing his four foot erection. There was only one thing for the two to do now.

Further their loving by embracing each other. Rainbow Dash pushed Big Mac to the floor and admired his rod. “Oh Big Mac, all this for me? This is too much you shouldn’t have really.” She began to position herself above it. Her pussy wet from excitement wanting to take it all in. As Dash began to lower herself, she moaned out loud. “Ahh, so long.” She panted as best as she can, taking the immense dong inside her.

The three fillies stopped arguing as they heard Dash scream out in pleasure. Scootaloo spoke out first. “Umm girls, I don’t think this is going exactly as planned…” She began to back away slowly.

“Geez you think Scoots? I thought your idea was great for once.” Sarcasm in Applebloom’s voice, as she followed closeby.

Sweetie Belle said nothing too disgusted by the images in front of her. The three fillies quickly got out of the barn while there was still room for them. They weren’t sure how much more the barn can take of the two growing lovers. The barn was only forty high and about forty long as well, the girls couldn’t tell how big Rainbow and Mac were when they left. Soon enough they heard the barn creaking and struggling to hold whatever laid inside, but they knew all too well.

Eventually the barn exploded showing the now heavily muscled Big Mac, with busty Rainbow Dash still on top of him, riding him to show her love for him. By now they were both possibly forty feet, the barn couldn’t contain eighty feet of lovers.

“Looks like the barn will need to be rebuilt again huh?” Rainbow joked as how the barn always seems to break.

“Eeeyup.” As Big Mac would always say, giving everything his lover wanted.

“Oh yes, Big Mac, faster, I need to feel more of it inside me, it feels so good.” She moaned outloud, the sex further increasing their height to heights never thought possible for the anthro race.

Their titanic bodies inched ever closer to the fillies, they almost froze and got squashed but luckily Applejack heard all the sex happening. “What are you three doing? Don’t ya’ll see them growing, get going, Twilight will have an answer.” With that the four of them started racing towards Twilight’s library hoping she would have an answer.”

Applejack didn’t have time to worry about the other folks running around wondering what to do, she had to get to Twilight and fast, hoping there was a way to stop her friend and her brother from growing to proportion big enough to destroy who knows what. Finally arriving at Twilight’s house, she began to knock.

“Another interruption? Who is it now?” Twilight screamed annoyed.

“Twilight, my sister and her friends did something weird to my brother and Rainbow Dash, I don’t understand.” Applejack screamed through the door hoping that Twilight would hear her. She kept banging on the door. Finally the door opened up revealing the purple anthro unicorn. Naked.

“What kind of weird thing are they doing exactly?” Twilight questioned, but soon saw the answer herself when she noticed the combined two hundred feet of lovemaking happening from too far away. Her mouth dropped. “Oh you gotta be kidding me?”
“What do we do Twi?” Applejack was in a panic.

“I honestly don’t know Applejack, I’ve never seen anything like this before. We have to get everyone out of here before Big Mac and Rainbow Dash destroy the town.” Twilight went back inside putting on some clothes and grabbing Fluttershy along with her. “I can explain later, right now we need to evacuate.” Both Fluttershy and Applejack blushed at having seen each other at an awkward time. As the five of them started getting out of town Rainbow Dash and Big Macintosh kept going at it, nothing stopping their sex or their growth. Ever fueling by the pleasure that they feel. Soon each one was about five hundred feet, the town was long gone.

Twilight was somehow able to manage to move everyone out and into Canterlot where they would be safe with the princesses. “That was close. Alright so what happened exactly Applejack?”

Instead of Applejack, Applebloom spoke up. “It was our idea Twi, we just wanted to try potion making again and we wanted my big brother to fall in love with someone, so we found something called Love poison plus. The description looked fine to me, it said “This is an improved version of the Love Poison, the + means the love will grow more and more over time.” But love had “rs” after it and it was crossed out.” She quickly said.

“Why would you use that? Can’t you two read?” Celestia’s voice boomed nearby, and finally she appeared in front of them. “That is a forbidden potion. Where did you find the recipe for that?”

“Umm we found it in the same book as the original love poison potion.” Applebloom said terrified of what she has done.

“That potion is chaos magic, created long ago to try and destroy this kingdom. Luckily my parents were able to control their size and sex before things got out control, like those two.” She pointed out in the distance. It wasn’t hard to miss the two colossal lovers.
They must have been a mile by this time.

Rainbow Dash’s curves had come out very nicely. Her breasts about a I cup at this time, her hips wider than normal, and her butt able to fully take Big Mac’s penis and more! Big Mac’s rod itself must have been about a third of his size or so. They were able to see it as they changed position, looked like he wanted some titty action. As Rainbow Dash started to turn around putting her mountain sized boobs on his gigantic rod. As she moved up and down, Big Mac started to lick and bite down on her nipples. Had she been normal size they would probably be as thick as soda cans!

“Unfortunately there is nothing we can do. They are in a haze of lust, sex, and growth. Nothing will stop them. We are doomed…” Celestia said with much dread in her voice. The setting turned gloom as everyone heard her and waited for the inevitable to happen.

Eventually the screams of pleasure could be heard all over Equestria, as Big Mac came all over Rainbow Dash’s boobs, gallons upon gallons of semen spilled all over her, some on himself, and whatever was left of the ground underneath them. Each about ten miles now and still going. Rainbow Dash needed more. Big Mac needed more. In one final attempt Rainbow got up and brought herself down on his pole inserting into her moist snatch once again. Waves of pleasure filling both of them.

The Love Poison seemed to love this kind of position the most, as their growth kicked into overdrive. Big Mac knew he was big, but feeling himself fill more and more of Rainbow Dash was incredible, he wished this would never stop, he needed to be bigger and he needed it to be bigger also. No one will be bigger than him, not even he himself.

Rainbow Dash couldn’t get enough of it either. Every second of sex and growth was pure bliss for her. Her pussy taking more and more of Big Mac was incredible. She never thought such a possibility was possible. She just knew she needed more, and she hoped he needed more. Which was true, he did want more.

As the two developed a rhythm for each other, they kept screaming for more. To be bigger, to keep going. Hoping nothing would stop them. But some things have to end. Finally with one last push, both of their released their cum everywhere, and with their they grew so fast they had left the atmosphere of the planet and hovered around the planet. The planet so small in fit perfectly in the cleavage of Rainbow Dash. But they didn’t want to destroy it. Everyone they cared for was there. So instead they hugged it as gently as they could, between them, waiting for the moment to start again.
