It is a warm spring day in the city of Canterlot. The streets are bustling, as ponies wander about with their daily activities. As you walk through the town, you notice a certain pony pushing a rather large, heavy, blue piano. You walk up to Rarity as she pushes the piano. You call out to her and catch her attention, catching her saying something about a band practice with Twilight Sparkle, Fluttershy, Rainbow Dash, Applejack, and Pinkie Pie. You had thought of joining up with their band, but Twilight Sparkle insisted it just be the 6 mares and Spike. Rarity backs away from you as you approach her.
"Please back away! I'm not wearing deodorant today and I'm all sweaty! I must insist!"
You have a smirk on your face as Rarity cowers from embarrassment.
"Don't worry Rarity, I'm sure your armpits smell as beautiful as you are," you flatter her, not sure if the pits between her legs and barrel could be called armpits. Rarity perks up and looks at you with a confused and disgusted look on her face. Eventually her face turns to joy and expresses her understanding.
"Oh, if you really like how I smell, then why don't you come over here and take a big whiff."
You oblige and approach the pale sweaty mare slowly as you try to detect her scent. Once you are an arms-length away from Rarity, the sour pungent smell of onions hits you in the face. At first your reaction is repulsion but then your dick starts to fill up with blood as Rarity smiles at you and asks, "Do you like it?"
Your dick reaches full capacity and feels like it is about to burst. You struggle to give Rarity an answer, no longer able to hold in your desires. You grab Rarity by a front leg.
"Oh my, can't get enough of that stink can you?" You struggle to pull Rarity's top off.
"Be gentle!"
After several awkward seconds of trying to get to the pit of gold, you manage to strip Rarity down of her top. Rarity giggles. You waste no time and snort every molecule of Rarity's essence into your nose directly from the source. Her scent is intoxicating and causes your penis to fill up with even more blood. You feel like the blood vessels in your penis are starting to pop. Before you get too far, though, Rarity stops you.
“Oh my, I have to get this piano to the music hall soon! I need to find deodorant, we can meet up later if you want."
She gives you a wink. Rarity grabs her saddlebag and struggles to find deodorant inside. You aren't finished with Rarity, though, and grab her leg again.
"Oh come on! You don..."
You waste no time and slap your tongue directly on Rarity's armpit. Slowly you move your tongue up and down, can feel the long hair of her unshaven armpit, or whatever you would call it, prickling your tongue.
“Oh..."
After about a minute of licking both Rarity's armpits, you can no longer hold onto the pressure built up in your penis. Your penis explodes with your pants still on and semen starts to drip down your leg. Rarity notices that you stopped and starts to see a huge wet spot on your pants.
"Finished already? Aww.. At least you made me all fresh again, now I can make it to the music hall."
You collapse onto the ground, twitching as you continue to orgasm. Rarity picks up her top and puts it back on. She walks towards the music hall and looks back at you.
"See you after practice," she says with a wink.
While Rarity attends her practice, you rush to your house which is just right around the corner. You have to change your pants and underwear from your encounter with Rarity. It takes some time and by the time you return to the middle of the city, half of the rehearsal is already over. You have no idea why Rarity was pushing a piano as heavy as that, but it did give her that nice scent that you liked.
Your thoughts are interrupted when you hear the sound of the mare's hooves. You look up in time to see Rarity, the object of your affection, descending the stairs of the music hall. You call out to her and catch her attention again, confused.
“Oh! Hello, you look confused. Today was only a half day,” she explains, the mare covered head to toe in sweat. You look her over and feel your cock twitch. You ask her about her current state.
“Oh, yes, Pinkie Pie wanted me to try out a drum solo. I tried, it sounded awful, and it made me all sweaty!” she complains to you. "You know how much I take pride in my appearance."
As soon as she mentions sweating, your pants bulge out. You grab Rarity by the hoof and run off, pulling her into a dark alley. Before she responds or says anything, you pull off her shirt again and shove your nose into her pit. You sniff deeply.
“I've seemed to have lost my stick of deodorant and of course the music hall has no showers, but I guess you don't care about that, do you?”
You shake your head and give licks to Rarity's hairy armpit. You let out a loud moan as your bulge gets bigger. Rarity giggles and decides to humor you, using her magic to unzip your pants. Out springs your big dick, throbbing in the hot air.
You reach around her body and pull off her top and dress, letting her large C cup crotchbreasts spill out. You move from smelling her armpit to rubbing your face on the sweaty breasts. You do this for a while before giving her a small shove.
Rarity falls to the ground, confused at the sudden push, but her protests aren't vocalized when she feels a nuzzle against one of her hooves. She looks down and smiles, watching you as you shove your nose against the pungent underside of the very sweaty hoof. You're not very surprised to see that she's not wearing socks.
You give a lick to the underside of that hoof, letting your tongue slide all over it.
“Oh, I never get a chance to clean there, thanks! And I hate the feeling of socks.”
You quite enjoy the pungent, grimy taste from the bottom of her hoof. Rarity ends up shoving her whole hoof into your mouth as you suckle and clean it, Rarity taking the lead. You nearly cum right then.
Suddenly you find yourself on your back, Rarity copying your earlier action. You stare up as Rarity pulls out a pair of soaked panties from her bag and shoves it on your nose. You inhale sharply, your cock throbbing and dripping with pre.
“I was lucky I brought an extra pair of panties to put on. I got completely soaked in sweat, even down there,” she says with a sly grin. “But I bet you're hoping I had.”
You were indeed hoping that, thrusting your cock into the air as more and more pre leaks out. You watch as she pulls her panties down that she was currently wearing, not quite as sweaty as the ones in your mouth. She drops them onto your throbbing member as she squats down.
She shoves her stinky, sweaty, smelly pussy against your lips, grinding a little. Cum drips out of her snatch and into your mouth.
“Sorry about the cum, I had to do SOMEthing to convince the owners to let us practice in the hall.”
All the tastes and smells set you off, soaking the panties on your cock in your cum. Rarity smiles and stands back up, masturbating furiously as she stands over you. The rush of possibly getting spotted spurs her to work quickly, the mare squatting back down again and shoving her pussy back on your open mouth. It doesn't take long for her to have her own release, her pungent femcum dripping out into your mouth.
“Thanks, I really needed that,” she says before smirking. “You know what, I'm making you my personal shower away from home.”
She snaps a collar around your neck and drags you off. You're hopeful she'll use you every day, after every workout, and possibly after every fuck session.
