They emerge onto the outskirts of Slut City.

The air was thick with fuck-musk. It hung like a cloying fog along the walkways between buildings. To David's surprise there were no roads to speak of – no cars revving along, running over squirrels and drunk pedestrians.

Instead, tree-lined paths extended in every direction, dotted with glassy booths and grassy common areas. All the scantily-clad bodies he saw appeared to be human, though they came in all shapes and sizes. Some were lanky like him, others draped with meaty folds; the skin colors and hairstyles among them were countless.

He turned to see that Kana was already marching off toward a booth between a couple of benches. David trotted along behind her, bumping into people as the surrounding overload of bare tits sapped his spatial awareness.

A scrolling, digital marquee atop the tall, mechanical structure proclaimed that it was an "EZ-Kum Station" – and it seemed to be made up of stacks of individual glass boxes. A gallery of spitty, cummy, crying faces groaned and sagged from the shiny wall; women of every description stuffed into transparent crates with their arms and legs folded underneath them.

"Damn, what's this thing?" David relished, cock engorging in the breeze.

"No idea! These weren't here last time – hi," Kana caught the eye of one of the women crated at waist-height, but the pale-faced prisoner ignored her.

"Hey man, what's up with the boxes? These free to use?" A hairy guy in a leather harness paused when David jabbed at his shoulder. He looked at the crates, then back at the little hornball grinning like a moron.

"They're prudes, just hit the button on the one you want." The hairy guy explained it like he'd been asked how to flush a toilet.

"Prudes?" Kana asked over her shoulder, tracing her fingers through a streak of cold jizz on one of the girl's faces.

"Yeah, like – they're not into sex. You guys aren't from here? Mayor finally issued an ultimatum a few years ago. 'Prudes get servitude,' that whole slogan?" The vacant look on their faces betrayed their ignorance.

"Just hit the button," the guy gestured impatiently, and carried on down the walkway.

"This one!" Kana chirped, and smacked a glowing yellow button on one of the crates.

"No, wait!" David had wanted to browse a bit before making a selection, but a big mechanical arm extended from the top of the booth. The crate slid out to the side on some chrome-plated tracks, and the mechanical arm locked into the top of it, hoisting it free.

The clear, hard box lowered to crotch height, so that the purple-haired woman inside was suspended perpendicularly in front of her selector. She was young, maybe 22, and had some sort of oxygen mask secured over her nose and mouth. The front of it had a rubbery seal that a dick could press through, to access her mouth which was pried open around a ring-gag.

As David stepped around to look at the little mask-gag combo, the back of the crate clicked open, exposing the girl's other well-used holes. Kana kneeled close to gaze at them, admiring how sloppy and stretched they looked.

"The fuck is…" David poked at the little rubber seal on the girl's mask, and a wisp of pinkish smoke slipped out. When it entered the shrimpy gremlin's nose he twisted up and shook his head. It felt like he'd just sucked in a huge whippet with his buddies in the restaurant freezer.

"God-damn!" He cackled. "They're high off their shit!" His dick jerked to attention, smacking the bottom of the girl's chin.

"Guess they keep them **** up? I wanna get fucked in a **** box all day," Kana pouted, stuffing a few fingers into the girl's oozing snatch.

"Prudes only, don't think you'd qualify," David said, pulling the girl's head up by her silky hair and working the tip of his dick through her gas mask. She sobbed once or twice before her mouth was completely filled with white meat, and the crate-arm rocked slightly while David started banging her face in earnest.

Her other holes puckered and twitched behind her while Kana tasted and toyed with them. The rest of the fuck-slaves watched or dozed in a ****-addled haze, waiting for their own buttons to be pressed and their own crates to be lowered.

"Ungh, fuck yeah. Wish there was a punishment for prudes back on Earth," David laughed, tightening his grip on the girl's hair. She retched and spilled thick slime around his shaft, which drained through the seal and down over his huge, swinging nuts.

"Are lots of humans prude?" Kana peeked around the crate with most of her fingers buried in the girl's cunt.

"Fucking unfortunately – the stuck-up, bitchy ones anyway," he thought of Valerie for a moment. "But it's kind of fun to break them down, though."

"I don't get it, who doesn't like sex?" Kana peered up at the wall of mask-gagged faces. She tried to imagine being like the celibate clerics back in her own world, and shivered at the thought of having "godly grace" as a substitute for a lifetime of big, pulsating cocks.

The crate-girl squirted over the elf's plunging fingers, splattering her chin and tits with pussy juice. "Haha! Maybe she does like it!"

"Don't think she has a choice," David sneered, 12-inch cock bulging her throat like a bullfrog. The girl's eyes were closed, but she twitched and moaned softly between gurgling hurls. He wondered who she was before she got stuffed in a glassy fuck-box. But it didn't really matter.

"Fuck yeah… here we go," he panted, feeling his nuts tense up. He bashed his hips against her face, almost knocking the mask askew, and another pink tendril of **** smoke slipped into his flared nostrils.

"Ohh… ghhaaaddd!" He hollered, and a few passers-by grinned at the sight. Kana was wrist deep in the girl's cunt as David blew thick reams of spunk straight into her stomach. It flooded the mask as it backed up in her throat and mouth – but there didn't seem to be a safety protocol in place to keep her from drowning.

He humped a few final spurts into her neck, then slowly tugged his meat out through the rubber seal. A splash of jizz dropped onto the walkway before the rest was sealed inside, and David watched cummy air bubbles slip from the girl's nose.

She jerked a couple of times, her face starting to turn a concerning maroon color, as Kana circled around to see what was happening.

"Should we help her?" She looked at David, then at the booth, which gave no indication what was expected. Maybe there were enough prudes to replace any that got fucked into disuse. Or maybe guys in Slut City didn't usually cum as much as David had.

The shitty little man-spirit scratched his head with one hand and massaged his cock with the other, looking around at the residents coming and going.

"Uhhh…"
