Exploring the butt plug store.

Arriving, the girls go in and immediately get to work perusing the store.

Now to answer some questions.

A quick search on your phone reveals that assholes in this universe self lubricate which would explain why all these girls were all so ready for anal sex. It makes sense, since constantly being ready to be fucked in the ass would normally cause damage. Assholes are more robust as well you notice. A quick google search results in much less warnings against anal sex. Bleeding is uncommon, and girls actually hold poop further up and poop less frequently as well. Weird, they clearly had to do some finagling to make this universe possible. Assholes are categorically considered a secondary sexual organ, and serves the strange evolutionary purpose of 'trying out girls.'

It's all fascinating stuff, but it essentially boils down to anal paradise, which is what you wanted. Entering the store after the girls, you walk down an isle of plugs ticking off names: Crystal, Cherry, Flower, Raspberry, Anise, Anal? One plug just says Sphincter. . . Are these really acceptable names?

You meet another girl browsing the isle. She seems to be just trying out plugs, pants off, grabbing stuff off the shelf like she's trying on shoes. Large bright red tassels are hanging from her butt with rings and jewels decorating them. She pulls at it roughly, and it comes out in sections exposing 4 individual black plugs. She tosses the slimy appendage on a bench littered with colorful plugs, shaking her head before slamming a big clear plug in her asshole. She crouches down and looks at herself in a mirror placed on the floor, spreading her cheeks.

"That's a nice one."

"You think so?" She stands up and bends over showing you her asshole being stretched by the glass plug. It's actually a hollow heart-shaped plug, made out of some sort of synthetic rubber. Her asshole faux-gapes at you and squeezes the material opening and closing it. You walk up to her and place your fingers inside of it. It's a fuckable, textured butt plug. It closes in on your finger, forming a nice tight seal. You notice it's delicately detailed with inscriptions and fine detail, the words "love tunnel" outline the rim.

"What's your name, Finger Trap?"

"Ha ha, no, here." And instead of telling you her name, she hands you a medium sized plug. Gabriella.

"You can call me Gape for short." Gape is dressed in a stylish blouse, super fancy looking jet-black heels, dangling gold ear-rings and a medium amount of makeup.

You notice the box for Love Tunnel sitting underneath the shelf. 350 dollars for this thing. Apparently it lights up the entire asshole and everything.

"It's a bit expensive though." Looking at the shelf you notice 350 isn't all that uncommon. Some don't even have one to try on, instead asking to 'see an associate for details.' Some made of gold, diamonds, and a few other rare materials.

"Yeah, I guess so. But I want something nice." She halfway agrees while straining her asshole, freeing your finger. She tugs out the plug part with a pop and snakes the rest of the cock-sleave out of her ass.

Looking along the wall you walk over to where the cheaper plugs are while she looks with doe-eyes at some diamond-golden plugs. Grabbing a display model on sale for thirty dollars, you walk over to her and jam it in Gape's asshole. Its a rather large plug and she has to brace herself on the glass display case as its spreads her wide apart.

"This one looks more your style" You press the button on the center of the plug.

Immediately, the plug lights up in rainbow colors, a glittery fan starts spinning around her ass as a pump activates sucking air in. Second later the pump audibly reverses, causing slapstick clown whistles to sound accompanied by some campy circus music. Accordions, fake sounding fart noises, toilets flush sound effects, and other silly sounds like splashes of police sirens and emergency bunker alarms. You reach for a hand pump dangling from her plug and squeeze the bag, which causes a muffled honking sound inside her ass which only adds to the cacophony. Each time it makes a buzzing sound, vibrating suddenly and causing Gabriella to perk up in surprise. You keep honking her ass a couple more times before turning a crank which went around the circumference of her plug. Much like a gyroscope, the interior of the plug began to rotate at extremely high speeds, oscillating in her asshole, almost fucking her and causing the fan to extend and twirl outward creating an even larger spectacle when she moved.

Gabriella looked a bit taken aback by this, but kept her butt thrust outward so as to not interrupt all the spinning contraptions in her ass.

"I don't know." She positioned her behind towards a mirror as whistles began playing La Cucaracha composed entirely of artificial farts, with lights changing colors to match the beat.

"It seems kind of... trashy."

"Trust me, this is what guys want, and this one works for you." Gape looked longingly one more time at a glittering gold plug.

"If you say so, still, I should keep looking. I can't go out in this. This ones, like, a joke gift or whatever."

"Nonsense, you should buy this one, guys will go crazy for you."

"Hmmm, I'll get it, but only because you're a guy and I'm a bit lost when it comes to butt plugs. Oh, god, is the Benny hill song coming out of my asshole?" As she says this her hand drifts to her crotch and a look of lust comes over her face. Her ass being a circus was having an effect on her, legs now squeezing together whenever particularly humiliating horns came from her ass. She picked up the the 'love tunnel' box and also one for 'the dazzler.'

"No, no, not this one." You take the love tunnel box and put it back and throw the dazzler box aside.

"You should buy the floor model." She looks confused but you pat her on the back towards the cash register. Reluctantly she walks away from you, looking back at you with raised eyebrows, clearly dumbstruck. You nod and smile to encourage her so she keeps going. She has to keep her ass pressed far out to keep from disturbing the contraptions while she walks. It was clearly meant to be used while the girl was bent over on hands and knees, probably at parties. You admire her backside as the star spangled banner starts playing out of her asshole as she waits in line.

The last you see of her, she is openly masturbating in line, and honking her own horn over and over again.
