Rainbow's Magical Boobs

Two weeks passed, and while the drink didn’t seem to take any immediate effects, but as the days trailed by, her bodily changes were becoming more and more noticeable. It was subtle at first, only seen after a few days, but then her chest grew, and grew, and grew, and grew. It seemed she may have over indulged, but Rainbow didn’t care. Her tits were growing, becoming bigger, absolutely massive. And by the end of the two weeks, she was striding through Ponyville with the biggest smirk on her face. Her boobs had swelled to the size where they could be considered more than twice or even three times her body weight, surpassing her friends, and maybe even rivaling the Princesses in size.

As well as this, her confidence was beyond inflated, taking pride in the stares she would get in town whenever a pony turned their head to look at her. Stallions glanced at her with a mix of curiosity and lust, while mares would glare at her with envy and maybe more than a little curious thoughts as well. Rainbow didn’t care, the only eyes that mattered to her were that of Green’s. Thankfully, her skills as a flier didn’t diminish from her gargantuan tits. Maybe a little slower at first, but being such an expert flier, Rainbow was able to figure out a new way to fly that didn’t get hindered or slowed down by these tits. So now with her Wonderbolt career still soaring, and a pair of beautiful boobs to show off that matched with her long mane, the mare was practically skipping whenever she walked down the street.

Returning home after another pleasurable jog, Rainbow walked in the house, panting a little. Stretching a little, she was amazed at her tits, even if she had to push at them a little to even get through the front door. But there was another side effect, or it possibly was a result of the mare’s growing confidence, borderline smugness. Rainbow was horny, incredibly horny, more aroused than she normally has ever been. As soon as she was in her living room, the clothes came off. The body tight fabric were flung about in all directions, nearly knocking some things over. Green, who was relaxing on the couch, looked up at his marefriend.

“Hey, babe. Did you enjoy your jog?” Green asked, smirking as he knew what was on her mind. “Looks like you’re still pretty pent up.”

“Oh, oh I am.” Rainbow smiled, her eyes narrowing as if devouring her lover’s body. “You…me…bed…now!” Green chuckled, getting up as he was ready for her.

“Fuck, fuck, fuck, fuck, fuck me!” Rainbow screamed out, riding the alicorn’s cock, feeling as he was stretching and filling out her soft embrace. Gasping as she lifted and slammed herself over her lover’s thick size. “You call that…fucking?” She hissed as she was clearly cumming on his length. “Fuck me with that cock! Break my pussy with that fucking…oh fuck!” Arching back, she came, spraying her sweet nectar all over his size.

Laying on the cloud bed, each rippling slam of Rainbow’s perfect ass was making it shake, Green was fucking upwards, loving every second of the mare bouncing on his dick. She was facing him, the body sized tits pressing against him, nearly crushing him as he was throbbing deep in her soaked, tight pussy canal. Reaching up, he was groping, tugging, teasing, fondling, squeezing, and suckling at the mare’s massive tits and nipples. The effect of this drink seemed to no only make her boobs huge, but extremely sensitive when she was horny. And now, she was cumming as her lover was suckling on her plump, soft nipples.

“Come on, come on, come on. Cum for me. Cum in your fucking, fat tittied marefriend’s soaking, fucking pussy!” Rainbow’s moaning and dirty talk pushed the alicorn stallion to keep going. Bouncing harder on this dick, while he was thrusting upwards, she could feel herself getting ready to cum again. “Give it to me, give it to me. I want it, I want it!”

“Don’t worry. You’ll get it.” Green chuckled, smirking as he tugged and squeezed on her nipples even harder. Rainbow gasped and moaned, her eyes rolling back, mouth giving off a goofy, orgasmic smile, and her tongue dangling out from the side of her lips. “Keep moaning for me. Show me how much you love this cock!”

Beating his length in and out of his lover’s pussy, Green’s cock throbbed, swelling as he was going to get ready to cum at any moment. Rainbow’s face was twisted in a pleasurable look, smiling as she panted and moaned. Her tits bounced, smacking, beating down at the stallion the same way his dick was punching deep against her cervix. The feeling was so good, causing her to clamp down on his length, wanting to milk it for as much as he could spare. It had been a while since the two had fucked, and Green’s balls were churning with the hot and heavy load that he was getting ready to pump deep inside of her.

“Keep going, babe. I’m getting close.” Green groaned, looking up at his love with passion in his eyes. “I’m gonna cum. I’m gonna cum right in that tight, sexy pussy.”

“You better…” Rainbow moaned, looking down at Green, though couldn’t exactly see him through her massive tits. “I want it, I want it, I want it.” Leaning over, she was practically smothering him in her breasts as she beat down her round ass faster and harder on his cock. “Give it to me, give it to me, give it to me.”

The two of them were panting and moaning together, pushing the other closer and closer to their next orgasm. The mare’s insides were tightening, her boobs pressing, nipples quivering, all while the stallion’s cock was throbbing, swelling, pulsing, and his balls were tightening against his body. Green moaned out, almost screaming, but the sheer volume of these fat tits was muffling much of the sound as he reached up. Wrapping his arms around his marefriend, he pulled her down as he slammed upwards. Rainbow gasped a breathless scream, feeling as the hot cum was flooding deep inside her pussy.

The warmth filled her, sending a pleasurable shiver down her spine as she quivered and cooed. Green’s cock pulsed and throbbed again and again as he let out more and more of his passion deep inside Rainbow’s pussy, not letting go as her womb was becoming saturated in his hot spunk. Laying forward, the mare cooed, cuddling against the alicorn stallion’s muscular body, loving not only the warm sensation of Green’s cum inside her, but how his strong hands were gently rubbing and stroking along her mane. Laying in their afterglow, the two of them were ready to let the fatigue kick in.

As she rested atop him, Rainbow’s chest started feeling warm. Moaning a little, her tits were almost pulsing as the heat swelled within until it suddenly settled down. Looking down, both her and Green’s eyes widened as the mare’s breasts grew, at least another full cup size. Stroking at her mane a little bit, the stallion’s cock throbbed in her pussy, but seemed to only stay hard. Rainbow’s body was also getting hotter again. Not only that, it felt like she got some energy back, as if she had rested for days, and was not just as horny as she was when she first got home; maybe even more so than before.

“So…wanna go again?” Green asked, playfully teasing the mare as he helped lift her up, pushing his strong hands against her soft tits. Rainbow moaned at his touch, her boobs becoming even more sensitive than before. “I’ll take that as a yes.” His marefriend smirked, feeling the throbbing hard cock still in her cum stuffed pussy, and started shaking and grinding again. “Alright, babe. Let's see how big we can make these babies!”
