You turn toward the group. "Maria, thank you for ying that out. Anyone have immediate questions about the contract?"

  Several moments pass. No one speaks.

  "Alright. Riviera, Musashi, Sango, Yoruichi, come with me for a minute. There's something practical we haven't covered yet."

  Yoruichi raises an eyebrow. Musashi tilts her head slightly. Riviera's expression remains composed. Sango adjusts the Hiraikotsu strap on her back but follows.

  The five of you enter one of the staging RVs. The door closes behind you. The interior is clean, simple, small kitchenette, bathroom alcove visible through a sliding door, benches along the walls.

  You sit down on one of the benches and look at them directly with an arrogant grin. "Strip."

  Sango's hand moves toward her weapon immediately. Musashi's eyes narrow. Riviera's posture doesn't change, but her gaze sharpens. Yoruichi grins.

  "Before you kill me," you continue, "Yoruichi probably knows what I'm about to demonstrate. Her purpose here is to sit on my p like a beautifully dangerous kitten and protect you three completely defenseless women from my overpowering might."

  Musashi snorts. "Defenseless."

  "Each of you could fold me like origami," you agree. "But humor me."

  Yoruichi moves first, shrugging off her jacket and letting it fall. Her shirt follows. She's not shy. Within moments she's down to nothing, walking over and settling onto your p with feline grace. Her weight is warm, her skin smooth against yours.

  Sango hesitates, then begins uncing her armor with practiced efficiency. Musashi unties her gi without ceremony, folding it neatly before setting it aside. Riviera removes her robes with measured precision, revealing pale elven skin.

  They stand before you, three warriors, beautiful, naked and wary.

  "Sango," you say, gesturing toward the kitchenette. "See that small metal basin? Turn the blue knob to the right twice, then touch the water coming out."

  She moves cautiously, fingers gripping the blue knob. She turns it. Water flows. She touches it.

  "Cold," she says, surprised.

  "Now turn it back to the left twice to stop it. Then do the same with the red knob."

  She complies. The water stops. She turns the red knob. Water flows again. She touches it, then jerks her hand back.

  "It's hot!"

  "Indoor Plumbing," you expin. "Hot and cold, controlled by those knobs. This is standard in modern homes. You don't need servants or fires. it's mostly automated, just turn the knobs. The exact design might change a little, but the overall result is the same."

  Musashi steps forward, testing the knobs herself. Riviera watches with academic interest.

  "Now," you continue, "all three of you, into the tiled alcove there."

  They gnce at the bathroom. Sango enters first, followed by Musashi and Riviera. They stand together in the small shower stall, clearly uncertain.

  "Gently twist both knobs once," you instruct. "Then turn the red knob a second time."

  Sango reaches for the controls. She twists both knobs. Nothing happens for a moment-

  Then water cascades down from the showerhead above.

  All three react instantly. Sango yelps. Musashi dodges sideways, pointlessly, since the water fills the entire stall. Riviera freezes, eyes wide.

  Yoruichi ughs against your chest. "You didn't warn them."

  "That's the point," you reply.

  Sango wipes water from her face, gring at you. "What is this?" anger meaningless with water flowing down their distracting naked bodies.

  "A shower. Running water from above. Adjust the temperature with the knobs like before, blue for cooler, red for hotter. This is how modern people bathe. No buckets. No hauling water. Just strip, turn the knobs and stand under it."

  Musashi runs her hand through the stream, testing it. "Efficient."

  Riveria studies the mechanism with clear fascination. "The water pressure is consistent. There must be a reservoir and pump system."

  "Correct," you confirm. "This RV has an enchanted water system. Infinite supply, perfect pressure. Every RV we're loading has the same setup. You'll never need to worry about water again."

  Sango turns the red knob further. The water grows warmer. She rexes slightly, letting it run over her shoulders.

  "This is... pleasant," she admits.

  “Some cultures figured this out a long time ago,” you say. “Bathing wasn’t just about being clean. It was... mental. A way to let the day drain out of you.” You shrug. “Hot springs. Bath houses. Communal soaking. People treated it like therapy before they had the word for it.”

  Your gaze flicks to the falling water. “Modern plumbing just made it private, on demand, and reliable.”

  Yoruichi shifts on your p, her voice amused. "You knew they'd like it once they stopped panicking."

  You gnce down at Yoruichi, one arm loosely around her waist as water continues to hiss behind the sliding door. “Indoor plumbing, is called a modern miracle for a reason.”

  She tilts her head, amber eyes bright. “Bold cim.”

  “You don’t notice it until you don’t have it,” you continue. “Hot water on demand. Clean water. No fires, no hauling buckets, no servants standing around awkwardly pretending not to listen. Just... knobs.”

  Behind the door, Sango adjusts the temperature again, shoulders easing as the water settles into something comfortably warm.

  “If the three of you had hopped in with your clothes and gear still on,” you add casually, “everything you own would be soaked. Armor, silk, leather, weapons. That’s why I had you strip first.”

  Musashi huffs a quiet ugh from the stall. “So this was mercy.”

  “Majoritively,” you confirm. “Dry clothes are underrated. So are beautiful women.” giving Yoruichi a light squeeze.

  Riveria’s voice carries over the sound of running water, thoughtful. “And the supply truly doesn’t run out?”

  “Nope. Enchanted reservoir,” you say. “Self-refilling, self-cleaning, no maintenance. Same for waste. Same for pressure. Every RV has identical systems.”

  You lean back slightly, careful not to disturb Yoruichi. “You could stay in there for hours if you wanted. Vigor and Sustenance enchantments will keep your skin from drying out, muscles rexed, no fatigue buildup.”

  There’s a brief pause. “...That seems excessive,” Sango says, though there’s no real protest in her voice.

  “It is,” you agree cheerfully. “Also completely unnecessary. The enchantments from your rings already keep you clean automatically.”

  Musashi gnces up at the showerhead, water running over her hair. “Then why include this?”

  You answer without hesitation.

  “Because even when you don’t need it,” you say, “warm water still feels nice.”

  That earns a quiet moment.

  Riveria closes her eyes briefly, letting the spray run over her shoulders. “I understand the appeal.”

  Yoruichi chuckles against your chest. “Most of us come from pces that already figured this out, you know.”

  “Yeah,” you reply. “Which is why I didn’t bother expining it to most of the group. You three just happen to come from worlds where ‘bath’ still involves pnning.” moving a hand up to gently cup her breast.

  Musashi snorts softly.

  Sango exhales, tension fully gone now, hands braced against the tiled wall as the water runs over her back. “I can see why people would consider this... civilized.”

  You smile faintly.

  “Welcome to one of humanity’s better ideas.”

  The shower continues to run, steam fogging the small alcove, not because it’s required, but because, for once, no one is in a hurry.

  Outside the RV, the harbor keeps moving. Inside, the lesson nds exactly as intended.

  You rub your hand across Yoruichi's thigh, keeping your tone easy, conversational.

  “So. You all already understand the first principle,” you say. “Water flows downhill. Gravity does the work whether you believe in it or not.”

  Musashi’s voice comes above the water, amused. “An uncompromising force.”

  “Exactly. In a lot of older towns,” you continue, “people were clever about it. They built bathhouses near hot springs, or uphill from rivers. Channel the water down through stone or cy pipes, let gravity handle distribution. Efficient, but very location-dependent.”

  Riveria hums thoughtfully. “I’ve seen simir designs. Elegant, but fragile.”

  “Right. Eventually water demand outgrew geography,” you say. “So people built towers, big ones. Elevated tanks or barrels. Rainwater collection, river pumps filling them when possible. You open a valve at the bottom, gravity does the rest. Cooking, washing, year-round supply.”

  Sango listens intently now, water streaming over her shoulders. “So height repced proximity.”

  “Exactly. Later, homes got smaller versions,” you go on. “A reservoir mounted above a stove. Fire heats the container, hot water rises, cold settles. Primitive, but it worked through winter. Over time that split into separate hot and cold reservoirs.”

  Musashi tests the temperature again, nodding. “This expins the dual controls.”

  “Yep. Red is hot. Blue is cold. mixing is comfort,” you say. “Eventually, cities scaled it up. Massive pump stations, pipe networks, electrical systems. So big that one household couldn’t possibly strain it. You just... turned a knob and never thought about it.”

  You let that hang for a moment.

  “The zombies broke that,” you add quietly. “Electricity fails. Pumps stop. Water stops. Toilets, sinks, baths, gone overnight.”

  Riveria’s expression tightens. “Infrastructure dependency.”

  “Very good. Now, RVs,” you continue, shifting the tone back to practical. “They’re designed as traveling homes. Normally they carry limited fresh water, limited waste capacity. You ration showers, you pn meals, you dump tanks.”

  You tap the wall lightly.

  “The enchantments remove those limits. Infinite refill. Automatic purification. No pumps to fail. No maintenance. Gravity still matters, but magic handles the rest.”

  Sango exhales slowly, letting the warm water run. “So this isn’t just comfort. It’s resilience.”

  “Bingo,” you say. “You could park one of these in the desert, the tundra, a ruined city, and it functions the same. Clean water. Heat. Sanitation.”

  Yoruichi grins. “And here I thought you just wanted to show off.”

  “Oh, I absolutely wanted to show off,” you reply without shame. “But also, this is why I wanted you to experience it directly. No expnation sticks like warm water after a long day.”

  Musashi chuckles. “You’re not wrong.”

  Inside the open-door shower, three wet-naked women settle fully now, tension resolved, no urgency. Just the quiet sound of water and the simple luxury of something that used to be invisible, now understood.

  Outside, the world is broken. Inside the RV, gravity, water, and a few good ideas still work exactly as intended.

  “This,” you say, voice steady, “is also why it’s important we get each of you your own RV onto the ship before they disappear.”

  Musashi’s attention sharpens immediately. Riveria turns slightly, listening more closely. Sango gnces at you.

  “Each of you gets your own space,” you continue. “Your own bed. Your own storage. Your own routines. If you want company, that’s a choice. If you want privacy, that’s also a choice. No one sleeping shoulder-to-shoulder unless they want to.”

  Sango nods slowly. “That... is more than I expected.”

  “The ship will have proper facilities,” you acknowledge. “Large communal showers, divided stalls, plenty of room. Functional. Efficient.”

  You gesture vaguely around the RV.

  “But this is different,” you say. “This is yours. A pce you can shut the door, control the temperature, take a shower at two in the morning without scheduling it around twenty other people.”

  Riveria’s voice is thoughtful. “A personal domain.”

  “Personal control,” you reply. “And once we’re not just driving them for a few hours at a time, once we actually live in them for a few days, you’ll feel the difference.”

  Musashi smiles faintly. “A warrior rests better when she controls her own space.”

  Yoruichi stretches on your p, her arousal visible, nipple hard against your palm. “You’re nesting.”

  You snort. “I’m logistics-nesting.”

  Sango turns fully under the spray now, shoulders rexing. “I understand why you’re prioritizing this.”

  You nod. “Comfort isn’t a luxury anymore. It’s sustainability. People hold together longer when they have somewhere that feels like theirs.”

  The water continues to fall, warm and steady.

  The three women step out of the shower stall, Riveria turning the water off leaving st, water still dripping from their skin. None of them move toward their discarded clothing. Sango gnces at her armor briefly, then back to you. Musashi's expression remains composed, unbothered. Riveria's analytical focus hasn't wavered.

  Yoruichi shifts on your p, her weight settling more deliberately. Her hand drifts down between you, fingers finding your waistband.

  "You're not the only one getting bored," she murmurs, tugging the fabric open.

  Your erection springs free. She lifts herself slightly, positioning, then sinks down onto you with aroused ease. Her inner walls grip tight, slick and warm.

  "Much better," she purrs, rolling her hips once.

  Sango freezes mid-step. Musashi's eyes flick to Yoruichi, then back to you, one eyebrow raised. Riveria's gaze lingers for a long moment before she returns her attention to the kitchenette.

  "Now," you continue, voice steady despite Yoruichi's slow grinding rhythm, "the stove works simirly to water. See those knobs?"

  Yoruichi leans back against your chest, giving the others a clear view of where you're joined. She moves deliberately, unhurried, her breasts swaying with each roll of her hips.

  Sango swallows, her eyes darting between you and the stove. "The... knobs?"

  "Turn one clockwise," you instruct. "You'll hear a click, then see fme."

  Musashi steps forward and complies. Blue fme springs to life beneath the burner. "Efficient."

  "Grab that pot from the shelf," you continue. Yoruichi clenches around you, her breathing deepening. "Fill it with water from the sink. Two-thirds full."

  Riveria retrieves the pot while Sango operates the faucet, their movements mechanical, focus split.

  "Now pce it on the fme," you say. "It'll take a few minutes to boil."

  Yoruichi's pace increases slightly. Her fingers dig into your thigh. "Don't stop on my account," she says, gncing over her shoulder at you with amber eyes bright with mischief.

  You reach around her, cupping her breasts, thumbs brushing over hardened nipples. She gasps softly, inner muscles tightening.

  "The ramen packets are in that cupboard," you manage, nodding toward the storage. "Open one."

  Musashi locates the package, examining it with clinical interest. "Dried noodles. Preserved."

  "Once the water boils, add them. The directions say three minutes, but you can tell easily when then they're not stiff."

  Yoruichi grinds down harder, her breath coming faster. The wet sound of her riding you fills the small space. Sango's cheeks flush. Riveria's composure cracks slightly, her gaze drawn repeatedly to Yoruichi's movements.

  "There's also an oven," you continue, voice rougher now. "That rger door below. Same principle, but it heats the entire enclosed space. Good for baking, roasting."

  Yoruichi moans softly, leaning forward to brace her hands on your knees. The angle changes, taking you deeper. Her back arches, head tilting back.

  "Watch the pot," you remind them. "When bubbles form, that's boiling."

  Steam begins to rise. Musashi tears open the ramen packet, waiting.

  Yoruichi's rhythm turns erratic. Her thighs tremble. You grip her hips, guiding her movements, feeling the tension coil through her body.

  "Now," you tell Musashi.

  She drops the noodles in. Yoruichi cries out, spasming around you as she comes, her nails raking your thighs.

  The three women watch in silence as Yoruichi rides out her orgasm, your hands steadying her, while squeezing her breasts.

  "Three minutes," you repeat calmly. "Then you drain the water, add the seasoning packet and it's ready to eat."

  You pull Yoruichi into a kiss as her trembling subsides, her lips parting eagerly against yours. Her tongue meets yours with ease, the taste of her still vivid as you hold her close. When you finally break away, she's smiling, amber eyes bright with satisfaction.

  "Alright," you say, gncing toward the kitchenette where steam rises from the pot. "Musashi, drain the water. There should be a strainer under the sink."

  Musashi locates it quickly, efficiently pouring the noodles through while Sango tears open the seasoning packet. Riveria watches with academic interest as the powder dissolves into the drained noodles.

  "Now stir it together," you instruct. "That's it. Grab some forks from that drawer."

  They divide the portions onto small ptes, each taking a fork and examining the dish with varying degrees of curiosity.

  Sango takes the first bite. Her eyes widen slightly. "It's... salty. Rich."

  Musashi tries hers next, chewing thoughtfully. "Simple, but satisfying. Efficient."

  Riveria samples hers with careful precision. "The texture is unusual. Soft but structured. The seasoning is... aggressive."

  "Welcome to instant ramen," you say. "One of humanity's greatest contributions to zy cooking. Three minutes, hot water, done. Most, myself included usually don't even strain the noodles, we just use less water and drink the broth once the noodles are done."

  Yoruichi shifts on your p, still gloriously naked and unbothered. "Most modern food is like that, isn't it?"

  "Exactly," you confirm. "Most modern cooking has forgotten all the steps you three probably know. No grinding grain, no butchering meat, no preserving vegetables. Everything's pre-made, packaged, stored in refrigerators or freezers. You just heat and eat."

  Sango frowns slightly. "That seems... hollow."

  "It is," you agree. "But it also means anyone can feed themselves without training. That's the trade-off. Convenience versus craft."

  Musashi nods slowly, understanding the cultural shift. Riveria continues eating, clearly analyzing the meal from multiple angles.

  Yoruichi gnces over her shoulder at you, grinning. "So what's next in your educational demonstration?"

  "Get dressed," you tell the three women. "There's one more thing your cultures likely didn't have."

  They move toward their discarded clothing. Sango ces her armor back on with practiced efficiency. Musashi ties her gi with quick, precise movements. Riveria dons her robes with measured grace.

  Yoruichi remains on your p, making no move to retrieve her clothes. You pull her into another soft kiss.

  Once they're dressed, you gesture toward Maria through the Telepathy Web. A moment ter, she steps into the RV, holding a small pill case.

  "This," you say, motioning to the case, "is anti-pregnancy medication. A simple daily pill that prevents conception. Allows for sex to be had commonly without risk."

  Sango's eyes widen. Musashi tilts her head thoughtfully. Riveria's expression sharpens with immediate interest.

  "Maria just mentioned there's the benefit of the master-servant contract," you continue. "Toggle menstrual cycles, manage biological needs. But Yoruichi doesn't have a contract yet. She might not accept it at all."

  Yoruichi grins, finally sliding off your p and stretching nguidly. "So I'm taking the simple version. One pill, every day, no babies."

  Riveria steps forward immediately. "May I examine one?"

  Maria hands her the case. Riveria opens it, studying the small white tablets with intense focus.

  "This is... pharmaceutical?" she asks.

  "Correct," you confirm. "Hormone regution. Prevents ovution. Completely reversible once you stop taking it."

  Sango looks uncertain. "So... intimacy without consequence?"

  "Without pregnancy," you crify. "All other consequences still apply. Emotional, retional, diseases, whatever. But no unpnned children."

  Musashi crosses her arms, thoughtful. "That would have changed much in my era."

  "It changed... almost everything in ours," you reply. "There's still no cure for stupidity."
