Thanks for the Mammaries...
The smell of testosterone, fresh sweat, and overcompensation fills the air around you. You breathe in it’s heavy musk, enjoying the sweet perfume of this place that has become a second home to you. Gyms have always been a place where you feel most at ease, most purposeful, and though the company at this one isn’t perfect, it’s better than nothing. Snowflake finishes his usual reps and turns to you for a brohoof.
“YEEEAH!” he roars.
You hear Iron Will scoff from where he’s doing a wallsit to rest in the corner.
“Only a hundred bro? Shit. If you’re not pushing yourself as far as you can, you can’t honestly call yourself a man!”
You’re so sick of his damn rhymes, but these two are your only workout buddies. No one else in Equestria has their kind of muscle and motivation, not to mention their unstoppable high-volume yelling which suits you better than the sweet coos of smaller, weaker ponies. Given that none of the female ponies you know are putting out, this is the best way to occupy your mind. Snowflake regards Iron Will warily, but says nothing.
“Bro, I know that’s not all just workout you got going on,” you grumble. “You’ve got some extra help from what I hear.”
“What’s that bro?”
“You heard me, bro,” you growl, standing and approaching him.
“Oh yeah Bro?”
“Yeah Bro!”
“YEEEAH!” roars snowflake, which effectively breaks some of the tension.
You and Iron Will stare coldly at each other, muscles twitching with masculinity. At last, Iron Will looks away and sighs.
“Ok, so yeah I’m using,” he says. “But it’s working so well. This new stuff is so fast acting, it just makes me feel like more of a man. If your muscles are faster generated, the ladies will be faster penetrated.”
You don’t acknowledge the rhyme.
“Steroids?”
“Yeah.”
“YEEEAH!” roars Snowflake.
You ignore him.
“No shame in that,” you admit. “You look great, so whatever it is seems to be working well for you.”
Iron will seems to brighten a little, he glances at you and his confident smile is instantly back.
“Want to try some? I can get my guy to give you more if you like it.”
You consider if that shit will shrink your balls irreparably. Ah, fuck it, you’re not using them here anyway. You shrug and hold out a willing hand.
“Sure, pass it over.”
Iron will fishes a small blue bottle out of his gym bag and passes you a large pill that looks like something they would force-feed horses. Yeah. Of course. That makes sense. You examine the pill a little warily and watch as Snowflake puts out his hooves and accepts one too. Iron will holds up his pill and you do as well, the three of you toasting as if you’re holding champagne.
“To being buff,” he bellows.
“To being buff!”
“YEEEAH!”
The three of you swallow the pills, and after a hearty brohoof and fistpump, you head on home.
----
You awaken in the morning feeling heavenly. Everything just feels right in the world. Your head is resting lovingly against some nice soft pillows…pillows? You don’t own any nice soft pillows. Oh. Oh crap, what are these?!
You sit upright in bed and let out a shriek as your newly grown, pendulous breasts bounce up and down, smacking you squarely and squashily in the face.
BREASTS?! Really, breasts? What in the princesses undergarments is going on here? You stand up, trying to maintain balance as your breasts continue to bounce. It’s hard to even stand straight with these things! Fuck, they’re probably at least double Ds if not bigger. Are these…are these from the steroids? Crap, they must be. All from wanting to be buffer. All because you couldn’t get fucking laid.
Grumbling, you curse the fact that you only have skimpy muscle shirts anymore, and that you have nothing that even resembles a bra. You tug a black shirt on, trying to hide your newly curvy figure, and throw on a jacket for good measure. You jog to the gym, hoping to find Iron Will. He’ll be able to fix this, you’re sure of it. You wrap your arms tightly around your chest and squeeze tightly to keep them from bouncing with each step. Fuck, running with these things fucking hurts! You reach the gym, already feeling an ache in your back. As you reach for the door you hear the sound of someone yelling inside. You pause, listening.
“Y-yeeeeah! YEEEAH! AAAWH YEEEEEEEAH!!!!”
Snowflake? You burst inside.
What you see makes your jaw and newly unsupported breasts drop.
There, laying on his back on an exercise machine, is Snowflake. He has his head thrown back, his arms at his sides, and there’s a soft rosy glow in his cheeks. His new breasts are naked, and you can see that they’re considerably bigger than your own. For some reason, you feel a twinge of jealousy at this, but it soon fades as you take in more of the scene. Standing over him is Iron Will, who also has breasts, but that’s not the really terrifying thing.
The terrifying thing is that Iron Will is leaning over Snowflake and sucking on one of his tits. With his other hand he tweaks one nipple harshly, squeezing it until it’s bright red. You can see a raging erection in snowflake’s shorts, and hear his muffled moans of ecstasy. It looks like it’s ready to blow at any minute. Your eyes widen and you wish you could look away, but that just isn’t happening.
“YEEEEEEEEEEEEEEEEEAH!” cries Snowflake suddenly.
All at once, a gush of white leaks from Iron Will’s mouth as milk shoots from both Snowflake’s breasts, the stream of the free one arching high into the air like a creamy fountain. The bulge in his pants also quivers and a dark wet stain spreads over the front of his crotch. What. What the fuck. Iron will looks up, milk still draining from his mouth. He smiles.
“Hey bro! Didn’t I tell you these pills were the shit?”
Wat.
"You gotta try this man, feels better than pumping Iron."
"Yeeeeeeah," Snowflake moans weakly.
You stand, frozen for a moment, staring at the panting Snowflake and grinning Iron Will. Then you shriek and turn, running headlong out of the gym without saying a word. You haven’t gone more than a step outside before you run headfirst into a pony. She cries out and you both fall backwards onto the ground. You look up, terrified that you’ve seriously injured whoever it is you just aggressively motor-boated.
“Shit I’m sorry are you…”
You look up to see Pinkie Pie staring at you wide-eyed. You glance down and realize that your jacket front is open. Your massive breasts bounce rhythmically beneath the thin fabric of your t-shirt and her pupils bounce up and down in unison with them. The cool air as put your nipples at attention, and they point out almost a full inch towards Pinkie. You reach up to cover them, embarrassed and blushing.
“A-anon, I didn’t…” she says, blinking.
You try to say something, but all that comes out is random uncomfortable sounds. Then, all at once, Pinkie grins.
“Ohmygosh Anon their fantastic!” she cries, clapping her hooves together. “Their so big and bouncy, and look, their pointing at me!” she giggles.
Still no words.
“Now those are some real funbags, they seem like a great time. I could use those, you know. It’d be just super-de-duper great!”
Use them? Is…Pinkie coming onto you? Because you have breasts? You had no idea she swung that way, but maybe that would explain her lack of interest in your elite buffness.
“You…like them?” you stutter.
“Oh yes Anon, they’re all big and squishy and full! Perfect for me.”
“I-I didn’t know you felt that way.”
Pinkie bats her eyes at you, and her smile grows.
“You know, the Cakes are out, and I could really use some help in there. It’d be just you and me playing games and having fun…”
You don’t need to hear any more. You smile and straighten up, almost losing your balance as your melons sway forward, bending to gravity’s whim. Pinkie laughs as your breasts bounce.
“Lead the way baby,” you say, giving her a cocky grin before reaching up to stop them from moving.
She beckons you towards the Cake residence, and you follow, a little less sheepish of your sweet-ass rack now. Maybe Iron Will was right. Maybe these steroids will get you the ladies.
----
Half an hour later, you sit completely drained in a chair. You feel weak, completely worn out. And your breasts, god do they hurt. But they’re not done yet, oh no. You groan as Pumpkin Cake and Pound Cake suckle at your tits, drinking every last drop of milk.
Pinkie didn’t tell you she was babysitting. She didn’t tell you that the Cake kids could chase down and take advantage of anyone if they had food using their flight and magic. She didn’t tell you that breastfeeding was all she’d ever intended. Why? Just…Why?
Pinkie looks at your pale and now dehydrated face, smiling.
“See Anon? I told you those boobies would be fun!”
