Rainbow woke up feeling heavy. Breathing in was a little harder than she expected. Not a chore or a problem, but she could tell that something was different. Something was off, or, more accurately as she looked down, on.
Her breasts were… Well, that had been puny before. While she was awesome in every aspect, being awesomely flat had always been a bit of sticking point for her whenever she hung out with her friends. Or, worse yet, when her boyfriend noticed how her friends had developed more than her.
Now though…
Now they were almost as big as her whole torso, and at least a good bit bigger than her own head. She bit into her lip, considering what could have done it recently as her fingers came down, tracing themselves around her now large, erect nipples. Just the gentle caress made her coo a little from how sensitive they were, something she was all too happy about.
As she gave them a hard squeeze, pushing them forward as her own hands sank into the base of her breasts, almost disappearing into the soft flesh, she waited for milk to come out. Nothing did though, unlike what she knew would have happened to…
She blinked a few times, her hands still playing with her chest as a few lights came on in her head. Fluttershy was currently stuck at home from an experiment Twilight had her doing, and Rainbow had snagged some of the milk her friend had had in the fridge. It had tasted oddly good though, and now…
She massaged her nipples, moaning again as she laid back, loving how much her skin gave to her strength. How wet just this small bit of stimulation was making her. It was something she had dreamed of, and it almost made her laugh that drinking her own friend’s milk had finally done it for her!
Rainbow wanted to keep playing with them though. Wanted to see just how amazing they were, and so began to push them up. They were so heavy, making her wonder how Fluttershy’s poor back didn’t just snap from holding her own set up, and they jiggled without support. Just a little nudge or jostle sent them spilling out every which way as if they had minds of their own.
As she played with them though, one thing kept making her bite her lip. How her nipples swayed. They used to be so small and like little nubs, but now she could just envision how far they would poke out of any shirt she wore.
However, with how malleable her tits were… She grabbed ahold of one of them, pulling it up and closer to her mouth, before opening wide for it. Her tongue flicked against it, tasting her own sensitive teat before she closed her lips tightly around it, sucking on the nipple as she moaned and laid back down.
It was better than almost any masturbation session she’d had already, and she could feel herself coming closer and closer to cumming. She bet all she would need to do was give her clit a firm pinch, and she be in heaven.
Slam!
She blinked a few times as she heard the sound of the door, smiling to herself as she wondered why she should put herself into heaven when she had a boyfriend who could.
Green Thunder, her boyfriend, was not entirely the sort of guy who would have agreed so readily. While being an alicorn would make one think he was, he wasn’t really an alicorn of anything. He was a decent flyer, a good writer, but mostly did odd jobs and played video games. He would say if anything ascended him, it was in fact Rainbow.
Not that he ever found he had anything to complain as he started up his Xpone and sat down on the couch, letting out a small sigh as he decompressed from the day. He had no idea if Rainbow was home or not, but that never really mattered with her. She decided whether or not she wanted to hang out and what they were doing, so even if she was home, he was better off letting her come to him.
And then he felt something he sometimes dreamed about. It was maybe the one thing that could make his life better, but right now, it made his body freeze like ice. Two, large, soft mounds pressed into his back, the heat from them beating against his neck as two, long, blue arms wrapped over his chest. “Hey there, stud. What do you think you’re doing?”
The voice was Rainbow’s. The color was Rainbow’s. The boobs though? Green almost threw himself off of the couch if Rainbow didn’t keep him on it, not wanting to somehow be caught by his girlfriend flirting with another mare.
When she came around the couch though, it was her, but also… not? Maybe? He wasn’t sure, but he definitely couldn’t take his eyes off of her.
Rainbow wore nothing to cover her nice, lithe hips or stomach, which was something she had done before. She had even before come to him dripping wet like right now and obviously in the mood to fuck. It had been hard for him to properly handle the suddenness of it then too, but now… With her breasts… It was almost impossible.
It didn’t help with how they were presented. He knew better than to say that she needed to cover them, as she was likely already ready to ay they were, which was about half true. After all, he could see about half of her areolas under her shirt. Of course, that was because the tight, small shirt barely stretched over her any of her chest, and sank in tight against it at the bottom of the hem, making sure it was all too apparent just how soft they were. What he could do them with his hands, or with his ever rising cock.
He tried to stammer something out as Rainbow stepped closer, her chest swaying from side to side. It was hypnotic to him, and it froze him in place as she started to crawl over him, one of her hands brushing against the growing bulge in his pants. “So, notice anything new yet?”
He swallowed hard, his cheeks turning an ever brighter shade of red as her hand began to undo his pants. He… He needed to stop this. Needed to get at least an explanation first, but it looked so good, and felt so good that… Green didn’t know how to respond before his cock was out, giving Rainbow a standing salute that she smiled at.
Her hand ran along his shaft as she asked, “He sure seems to have. I wonder though, could he even handle a hug from my new friends?”
Green smiled a little at the joke, internally wondering about that himself before finally asking, “I-I don’t know. He might want to know where they came from first.”
Rainbow only half listened to him, letting herself lay on top of him. Her shirt kept the space between her breasts tight, making a small, tight hole between them for his cock to slide into. It was warm and soft, yielding to Green’s throbbing member, and he bit into his lip as she giggled. “I would probably say one of Twilight’s experiments went right for once, even if she doesn’t know about it. I promise they’re entirely natural though.”
Green didn’t doubt that for a second. As much as he bet a surgeon could do wonders given enough time, one day wasn’t going to get these perfect balloons grafted onto his beloved. It was amazing for her to have them too, and he wanted to just let the matter drop as his hips thrusted into her cleavage, moving on their own as they merely wanted more of her thick flesh.
However… A small part of him froze. Green didn’t think of himself as a bad stallion, just… unremarkable, something his alicorn status made all too clear to him at times. The day he’d mustered enough courage to ask Rainbow out was a day he held as special to him. A time when he managed to be a stallion worth someone so amazing, and for the most part he thought he had kept to his promise since then to make sure he stayed that way.
But these changed things to him. They obviously felt nice to her as she hummed and joked about how his cock felt between them, but what about another stallion decided to come? When her new found… gifts brought along a suitor that deserved her more than him?
All the while he continued to push against those breasts, his cock grinding against them while Rainbow pushed her chest against it. She made sure that the pressure kept up on every inch of him. That his hips knew only her body and heat, and that his tip didn’t find it rubbing against her shirt, though it was barely on at this point.
Green loved how hard she worked at this, but she shouldn’t be. He should be trying to show her what he could do and-
“Shut up, dummy.”
Green opened up his eyes, staring into Rainbow’s fierce, purple ones as she stared up at him. She… she didn’t stop, not entirely, but the pressure felt different. Instead of two pillows on top of him, they were now a case trapping his cock where it was, only allowing it to move a little at a time as his precum soaked into her coat. He hadn’t said anything, from what he could remember, and swallowed hard as she continued to look at him. “W-What?”
“You’re getting that stupid look on your face that you do whenever you’re being dumb.” Rainbow lifted herself up, letting part of his cock breathe, but that only made the teasing and friction against his tip all the more apparent. “When i saw these, this is what I wanted to do. I wanted to have fun with them with the one I love. Show the one I love the fact that I finally was complete because…”
She bit into his lip, looking adorable as she looked to the side, her thick, fluffy hair covering part of her face as her cheeks turned red. “I kept worrying you’d leave if I didn’t get a boob job soon, so… I want you to like them. I… I do.”
Green was speechless for a moment as he heard for one of the first times from Rainbow her be afraid about their relationship. That she felt insecure. That she worried about losing him, all while looking about as cute as she ever had with him. It… It was too much, and as he pushed up into her breasts, he didn’t respond, but only grunted as he felt his shaft tighten, and his seed be pushed out of his balls.
It caught Rainbow off guard as his cum came out from inbetween her tits, bubbling up from between them, before getting somewhat mopped up by her shirt. She blushed as Green laid back, blushing at how suddenly he had just cum, before she peeled off of her shirt and began to properly clean herself off, smiling at him as she looked between a few strands of hair. “Can… Can I take that as a yes?”
Green smiled, his cock quivering as it quickly recovered from his climax, already standing back up for her. He could see her glistening between her thighs, and he began to push himself up, wanting to do something about that after the amazing gift she’d given him. “I did. I really did, but now-”
“No.” Rainbow, with one hand, pushed him down, crawling over him as she smiled, nothing hiding her body now. She grabbed one of his hands and led it to her breasts, letting his fingers sink into the soft bosom as she moaned. “I… I just want you to be able to focus on these. That’ll be more than enough right now, I promise.”
Green opened his mouth to argue, but then decided to close it. Rainbow had just pushed his fears back, and he was being told to play with some of the largest breasts he’d ever seen by the mare he loved. For him to bitch about this anymore was just going to risk him missing out, and so he reached out with both of his hands, grabbing ahold of them with everything he had.
They were unbelievable soft, but he could tell there was a limit to it. After all, it was still Rainbow’s body, and she was almost as strong as they came, so they weren’t going to sag or fall as much as Rarity’s or Fluttershy’s. No, he bet that she wouldn’t need even half the support those two did to get them to stay up.
Her nipples were nice and large, grinding against his palm as he began to message into the chest. They were firm and he could tell that teasing them was almost ecstacy to Rainbow as she let her slit slide along his shaft, soaking it in her arousal as she panted. It was almost too good for him to believe in. At least, without lines like, “I don’t know if I actually need to hop on you if you’re going to be this happy just playing with them.”
Green wasn’t going to just let her tease him though as his fingers came around her nipples, causing her to perk up. “Wait, I don- Aaaah!”
Hearing Rainbow moan like that as her juices poured over his waist was wonderful, and it was all because of simple pull on her nipples to bring her closer. She panted against his forehead as he kept teasing her nipples, letting them hang in front of his face as Rainbow finally began to lift her hips.
Green let his breath beat upon her nipples, keeping them there by holding each between two of his fingers. His thumbs ground against them, pushing them down while they couldn’t hide before going in circles like on a joystick to make sure he forced even more of Rainbow’s small, cute moans out of her.
And then she let her hips drop back down, her pussy eating up the tip of Green’s cock easily, before she slid down along it, her pussy opening up for the throbbing member it knew all too well. Green groaned in response as she fell upon him, her chest smothering him as he thrusted up into her, stirring up her insides as they fell into roles they knew all too well.
Except, now Green could do something new while she sat on his lap, weakly bouncing on his cock as she tried to calm herself down enough to find some strength in her legs. They were usually just out of reach, but now they were begging for it. Her nipples were practically trying to open his mouth at this point after all, and he wasn’t going to tell them no.
He opened his mouth, letting his hips rock Rainbow as he let her breast fall into his mouth. Her nipple was sweet to taste, with only the slightest hints of her sweat as he suckled on it. Her pussy tightened up even harder the moment he began suckling on her teat, and Rainbow mumbled, “Shtop. That’s… Too… sensitive…” before simply collapsing again, unable to do much more than enjoy what she was being given.
Not that he didn’t have plenty to give as he sucked ever harder on her nipple, unable to get more of her as he reached around her. She felt so good, but there was one part of anytime they did this, and he wasn’t going to forget about it. Not when it made it feel like more to him than simply loving her body, and that was especially important today.
So, as the two moaned against each other, his hard cock slapping into her thighs as she rode him, one of his hands gripping her breast, while the other tenderly, sweetly found the top of her head. Her bright, rainbow mane was there. That mane that had caught his attention in the first place, and he made sure to always find when they were intertwined with each other.
Rainbow panted as her breath beat into his ear, her words still coming out in gasps as she whispered, “I’m… right… there. Give… it…” her hips lifted up unexpectedly, catching Green off guard as she brought them crashing down, screaming as she did so, “Me!”
Green’s eyes almost popped out of his skull as her pussy felt like it was trying to squeeze his cock off all of a sudden, and his eyes rolled back as her folds began stroking his cock, calling out for every single bit of cum he could manage. He almost didn’t think as his body tensed up, her teeth grinding on the nipple between them for a few moments, instead of just chomping down on it as he came. It only led to more moans and pants in his ear though as thick ropes of his cum poured into her, filling her to the brim as they both collapsed.
Rainbow didn’t add anything. She only slowly shifted herself, making sure her chest didn’t smother him as they kept themselves together, his lightly grinding inside of her as they held each other. Green simply reached up, continuing to stroke her hair as he snuggled into her soft pillows, his breath gently beating against them as it slowed.
And soon enough, they laid there like so many times before. His hand ran through her hair once more. It was as long and soft as it always had been. He couldn’t help but smile at himself as he remembered a day when he had told her that her hair made up for her small chest. How he loved how it found her ass, before then trying to touch it and getting slapped on the hand for it.
Those were their early days together. Now… Now he could probably get away with grabbing at her chest. To go to sleep with his fingers deep inside the flesh he always coveted. It slowed his hand as he considered it, and he sucked in a tight breath as his fingers wove themselves into her long strands.
Rainbow’s hands squeezed his shoulders hard, forcing Green to wince in pain before she said, “You take that hand off my head, and you aren’t touching my breasts for a week. Got it?”
He looked up, smiling at the threat, just as Rainbow looked down. She was trying not to smile, but her normal warmth for him was there in her eyes. He probably could have gotten away with teasing her breasts, just for today at least, but he didn’t. They were just another new way he had discovered that she was perfect, and she made sure she knew it by whispering, “I love you.”
Rainbow didn’t say anything. She liked actions more, bending herself over a little in order to bring her lips to his. It wasn’t a long kiss. They didn’t need one right now, especially while it was so uncomfortable, but a small one like this…
Yes. They both agreed that it was the best way to end such a wonderful day before their arms wrapped back around each other, and their minds went to drift into each other’s dreams as they shut their eyes.
