Background Pony #999E
Twilight couldn’t help herself, even though she knew the consequences of further expression. Of what was going to happen to herself.
She began to reach out her finger…
It had begun a month ago. She had always been enamoured with her dear friend Fluttershy, but she couldn’t help but be drawn especially to said pegasus’ enormous bosom. It wasn’t until that fateful day a month ago, when an accident in her cottage tripped Twilight into faceplanting in that gorgeous bust, that she discovered Fluttershy felt the same way, the yellow mare trapping her face in her cleavage and encouraging her to motorboat them. That day led to much affection for Shy, and her stupendous spheres…
… and when Twilight awoke the next morning, she was astounded to discover the front of her pajamas had popped a button. After having been a steady C-cup for years, her OWN breasts had suddenly gained a couple of cup sizes overnight.
As Twilight and Shy began dating steadily, it wouldn’t be long before the unicorn began to see a pattern emerging. The pegasus absolutely loved her breasts being adored and played with, and Twi was only too happy to indulge her… but every time she did so, she would discover her own tops becoming even tighter the next day, her breasts having grown even bigger. By some mechanism she had yet to uncover, the act of giving Fluttershy’s breasts love and attention, was making her OWN breasts grow.
Even as this became abundantly clear, Twilight simply could not stop. Day after day, week after week, more and more, bigger and bigger. Her wardrobe was a shambles from the constant growth she was undergoing, and was forever having to re-find her center of balance as she became more and more top-heavy. She knew what was causing it. She knew it wasn’t going to stop unless SHE stopped. Stopped loving Fluttershy, and her own magnificent mammaries.
She couldn’t do it. Nor could she TELL Fluttershy what was happening, she knew the guilt would kill the poor mare. Already her lover knew something had been going on, having noticed and watched her growth over the past couple of weeks. A couple of days ago, she had offered Twi some of her old tops, to replace those casualties from the ongoing containment war.
It was one of those old tops that Twilight was wearing tonight. She had been spilling out from its neckline since the word go, lavender muffin-tops rising up and out into the air, cleavage fully on display.
My goddess. I’m almost as big as Fluttershy now.
And yet, she found it hard to worry about, as she wined and dined that night with her love, Shy herself having opted for something absurdly low-cut, leaving plenty of tempting cleavage for the unicorn’s eyes, no doubt with the intention of allowing said unicorn to take advantage of it later. An invitation to adore her wonderful marefriend, and her bountiful bosom…
Twilight couldn’t help herself, even though she knew the consequences of further expression. Of what was going to happen to herself.
She began to reach out her finger… and then lightly prodded the nearest yellow swell, eliciting a sigh, followed by a giggle from her love.
“Boop!… I love these girls.”
Shy blushed, though a knowing smile spread across her lips. “I know you do… and, you know what?”
The pegasus lifted a finger of her own, and brought it over to rest on Twilight’s own exposed boobage, tracing a circle on the purple surface. “Yours have been looking very lovely lately as well… they deserve a little attention too.”
Twilight was stunned into silence, even as Shy pulled back and took another sip from her glass-
wait… was that a trick of the light, or…
… did Fluttershy’s own tits… grow a little bit, just now?
Twilight couldn’t be certain… but she had a feeling she was going to really enjoy putting some new theories to the test tonight!
