> Be Anon, watching Rainbow Dash's soccer game
> Not that you even like watching soccer
> You just got swept up with the girls in "supporting your friend!"
> At least you are in good company, while being bored out of your mind
> Rarity is on your right, staring at herself in a hand mirror and touching up her make-up from time to time
> On your left, Sunset Shimmer has pulled her shirt up and is idly playing with her tits
> Nice
> You find it increasingly difficult to pay attention to the game
> Sunset looks at you quizzically
> "What's up?"
> You get an idea
"Rarity, Sunset, could I borrow your panties for a bit?"
> Sunset shrugs and starts to reach under her skirt
> "Sure."
> Rarity tilts her head this way and that, staring into the mirror
> "I'm afraid my hands are full right now, Darling. If you want my panties, you'll have to take them off yourself."
> You love this world
"Don't mind if I do."
> You slide your hands up her creamy thighs
> She lifts her bottom slightly, and you pull her panties down, stroking her silky skin as you move the underwear down her legs
> After a tricky bit with her high heels, you now hold a pair of warm, lacey purple panties in your hand
> Sunset taps you on the shoulder and hands you her red silk thong
"Thanks."
> She smiles
> "Anytime. Do you need a hand with what you're going to do?"
> You look her over, noticing a slight blush on her cheeks
"Why don't we help each other out?"
> Sunset grins
> "I was hoping you'd say that."
> You unfasten your pants and slide them down a bit, giving your erection room to breathe
> You pull it out of the hole of your boxers and wrap it in the soft fabric of your friends' panties
> Sunset grabs your erection in her slender hand, while her other one stuffs your left hand down her skirt
> Your hips buck at the sudden pressure, and she giggles
> "So sensitive."
> You roll your eyes, and start rubbing circles on her vulva
> She hums in pleasure, leaning against you
> You are suddenly very aware of the warmth of her breast mashed against your biceps
> Her face is so close, her eyes sultry, her lips parted 
> Your cock slides in her firm grip, thrumming with pleasure as the silk slides against the underside of your glans
> You pull her head closer with your right hand and kiss her on the lips
> She moans, hips rolling under the ministrations of your touch
> Her tongue instinctively wraps and wrestles with your own as you deepen the kiss
> You slide a finger inside her, searching for that one-
> She convulses, whimpering into your mouth
> Her hand clenches almost painfully around your dick, making short, jerky motions
> You groan, breaking the kiss
> She pants heavily, thighs clenched tight around your hand
> "That's it, hah, right there."
> You can feel the tension in her body build, her pussy pulsing around your hand
> Sunset's hand pumps your panty-clad dick furiously
> You can't help but thrust yourself into her grip, clenching your teeth
"Fuck!"
> She makes a low chuckle
> "Very nearly."
> You slide a second finger inside her, joining the first as you attack her g-spot
> Her breath comes in gasps now, and she crushes herself against you
> You are getting close yourself, an exquisite pressure building inside you
> Sunset whimpers with a tiny voice
> "Please, more! More!"
> Your fingers are starting to cramp but you oblige, plundering her depths with increasing speed as she coats your hand in her delicious juices
> She writhes against you, humping your hand like an animal
> "Fuck! Yes! Fuck me, oh Celestia, Fuck me!"
> It's too much
> You explode into the panties, the pleasure robbing you of your sight for a few heavenly seconds
> And she doesn't stop stroking
> You surge again and again, your cum soaking into the fabric, glistening between her fingers
> Thankfully, she slows to a stop as she comes down from her own orgasm
> The two of you lean against each other, breathing in sync
> Rarity titters behind her hand
> "Such a vigorous way to pass the time."
> You pull your hand from Sunset's crotch and start licking her juices off of it
"Don't knock it until you try it."
> Sunset gently extracts her thong from where it's plastered to your cock
> Rarity rolls her eyes
> "Please, a lady never improvises in such a manner. That's why I have two vibrators inside me at all times, in case I need some stress relief. Now, if you are quite done, would you kindly return my panties?"
> You pause to watch Sunset put on her semen coated thong, the side of her ass visible as she pulled the thong snug against her pussy
> Goddamn
> You pull Rarity's panties from your softening member and twitch at the stimulation
> You're still pretty sensitive
> You look at the fashionista, still preoccupied with her mirror
"Shall I put them back on for you?"
> "That would be ideal, Darling."
> You kneel down next to her legs and thread her feet through her panties
> Looking up her skirt you can see her perfectly shaved pussy, with a small pink plastic knob peeking out from her folds
> Once again, she rises to allow you access
> You pull her panties up high, the fabric conforming perfectly to the contours of her womanhood
> You cannot resist the temptation
> You let go of the sides of her panties and press your fingers through the cum-covered fabric, smearing your jizz inside of her
> "Oh!"
> You grin at Rarity's rosy cheeks and sit back down like nothing happened
> She squirms in her seat, and you can hear a low buzz start up
> "You tease! You are fortunate I came prepared, or else I would be quite put out with you."
> You kiss her on the cheek
"I am lucky indeed, to have such a beautiful friend willing to accommodate my desires."
> Rarity smiles in spite of herself
> "Flatterer. Now be still, and let me use you as a backrest."
> You nod graciously
"As you wish."
> The game continues, with Rarity shuddering in pleasure beside you, and Sunset resting her head on your lap
> All in all, you're glad you came
