>It's simple darling, just let me get your full measurements!
>In a flash, Rarity cups you, lightly fondling them.
>She puts a finger to her chin with her spare hand.
"Needs extra space in the groin, most definitely."
>She unbuttons your pants, staring directly at your boxer briefs.
"Poor thing, it must be suffocating in there!"
>She lets go and immeadiately puts her hand down your underwear, lightly clenching your limp member.
"Your measurements are incredible, Anon! You'll be a fine test for a more custom fit!"
>She begins to lightly tug on you. While it's one of the most simple things you can do, she makes it feel like she's had millenia of experience doing it.
>Your legs give for a moment, before you regain proper posture.
"Hold your horses there, cowboy. I haven't finished measuring you yet."
>A fire sparks in your heart, as you gaze into the hypnotic eyes of Rarity.
>She stares blankly at you, with a seductive smile while she jerks you off.
>Your legs continue to attempt to buckle under the pleasure, and you seemingly stagger each time Rarity reaches your base.
"Now dear, before we get you a new suit for prom, we need to test how well you can handle being in tight clothing. We don't want you looking like a trash bag, you know!"
>Rarity pulls up her skirt, bending down over the table.
>With her grip still on your diamond dick, she gives you a light tug towards her.
>Excitedly, you follow suit, while she pulls her panties down to her heels and spreads her legs as far as her cloth binding allows.
>She presses your cock between her asscheeks, slowly grinding against it.
>You halfheartedly place your hands on her silky ass, attempting to use her as a balance.
>Grinding against her, you feel her pussy and asshole rub on your shaft.
>Rarity is definitely into this teasing, as you hear light huffs coming from her.
>An Occasional 'Eep' comes from her mouth, and breathes gasps of relief while you pry at her with your tip.
>You wrap an arm around her waist, and start stimulating her clit.
>Rarity retorts by gyrating her hips, sending you into spasms of euphoria as the both of you writhe in your seperate throes of nirvana.
>Almost like an automaton, Rarity works you like you were on a semen collection farm.
"Nngh, that's it Anon! Just like that!"
>Despite you being the one who'd nearly broken, Rarity nearly collapses, only caught by your hand and your index now penetrating her.
>A wail is heard from her.
"YeEESSSss-SS!"
>Rarity pulls off of your finger, only to cum all over your hand.
>Her legs tremble as she slowly rubs against you, hearing her pained moans and gasps of air.
>A strain of nirvana flushes through you, as you mention to Rarity you can't hold any further.
>She pulls away from you, only to turn around and kneel, cupping her hands.
>Sticking her tongue out, she explores every inch of your girth, until you release thick hot strands of cum onto her face and into her hands.
>She searches for each sticky rope of your seed, and cleans her face, licking her hands and face clean, slurping your load up.
"Oh anon, I haven't had such interesting measurements since I was a freshman!"
>Rarity's hands drop to the floor, nuzzling your limp cock with her cheek.
>Squatting down to meet with her, wrapping an arm around her shoulder, she keeps her face rested against yours.
>Rarity pecks your cheek, as you sit there and embrace her.
"I'll have your suit done in no time, Anon. Just as soon as.."
>You silence her with a finger to her lip, as you caress her perfectly styled hair.
>Rarity gently drifts off in your arms, eventually you lean against the wall and slide down, allowing her to rest comfortably on your shoulder as she slumbers.
