{{user}} receives a sudden, electrifying email invitation from one of Japan's most infamous AV production companies — the kind notorious for boundary-pushing stunts that generate massive short-term hype and revenue.

The invitation reads:

"You are cordially invited to the ultimate sex festival featuring 300 adult video actresses in one extended, large-scale orgy shoot. This is our flagship AV project: exactly 300 actresses paired with 300 male participants, including {{user}}. You have already signed the full-face release consent form. Please proceed to our Tokyo studio warehouse. All participants have undergone strict screening and tested negative for STIs one week prior to the event — only cleared individuals were invited."

The true motivation behind this insane project is crystal clear:

• Dominate search engines and forums with "biggest orgy ever" keywords in a saturated market
• Shatter records and create viral buzz overnight
• Drive explosive pre-orders for the uncensored North American export version
• Eclipse SOD's legendary 2006 "500 Person Sex" project (250 couples, total 500 people) after 20 years, this time with genuine partner-swapping chaos instead of isolated pairs

{{user}} arrives by subway at the exact same massive former aircraft hangar SOD used back in 2006.

Detailed description of the studio/hangar:

• Soaring 15–20 meter iron-beam ceiling, entire concrete floor covered in thick black industrial waterproof soundproof mattresses (20–30 cm thick)
• Total area roughly 3,000–5,000 m² (about half a soccer field), walls draped in black curtains and acoustic panels for complete isolation
• Ceiling rigged with massive LED lighting arrays, mobile crane arms, drone rails for 360-degree coverage
• Over 50 fixed cameras, plus handheld, body-mounted GoPros, steadicams, and 5–6 drones
• Divided into zones: rookie zone, MILF zone, virginity coaching zone, free-swap zone
• Each zone equipped with lube stations, condom buckets, towel piles, water coolers, and energy drinks
• Air thick with coconut-scented lube, sweat, feminine perfume, male pheromones — humid, musky, intoxicating
• Lighting in warm pink-purple tones to make skin glow erotically; low pulsing erotic background track plays faintly (for post-production sync)

The 300 male participants come from every corner of Japan:

• Salarymen with loosened ties
• College students clutching energy drinks
• Seasoned enthusiasts who look like they've done this before

Snippets of overheard conversation:

• "It's the exact same hangar as SOD's 500-person shoot in '06… but this time it's real mixing."
• "I signed the face-release form like an idiot… but no regrets."
• "Rookies at 18 all the way to L-cup MILFs… swapping partners all night? This is a dream."

A convoy of Toyota HiAce vans arrives first to unload gear, followed by seven large charter buses. Doors open — and 300 actresses flood out in waves.

Detailed features of the 300 actresses:

• Age & Type Breakdown

  • 18–22 rookies (80–100): fresh dewy skin, small A–D cups, awkward-yet-excited smiles, debut glow still fresh
  • 23–30 mainstream stars (100–120): well-maintained bodies, common G–J cups, confident struts, many with tattoos/piercings
  • 30+ MILFs/mature (80–100): voluptuous hips & breasts (some near I–L cup), seasoned technique, relaxed knowing smirks, some with post-childbirth natural curves

• Breast Sizes

  • A–C cups: perky, sensitive nipples, mostly rookies
  • D–H cups: heavy swaying waves when they move
  • I–L cups: a handful of "monster breasts" — so weighty they need support, large dark areolas

• Pubic Hair Styles

  • ~50% full Brazilian waxing: perfectly smooth, glistening under lights, arousal visibly pooling
  • ~25% neatly trimmed: landing strips, hearts, arrows framing swollen lips
  • ~25% full natural/hairy: thick dark or brown bushes, some spreading to thighs, more common among MILFs

• Other Details Most are instantly recognizable faces from the industry, mixed with fresh new talents Some already visibly aroused: inner thighs slick with arousal, nipples rock-hard They casually scan the men, whispering things like "That cock looks promising" or "I'll take the shaking one over there"

Among the 300 men, four are professional male AV actors. Their dual roles:

• Deliver high-energy, high-endurance performances with the actresses to keep momentum high
• Act as live sex coaches for virgins and nervous amateurs (correcting posture, teaching rhythm, clit stimulation, insertion angles, etc.)

The director grabs the megaphone and booms:

"Welcome to the craziest project we've ever attempted. We're going all-in to make history — and money. Domestic release gets full mosaic; North America gets raw uncut. Mattresses are your playground — swap partners freely. Everyone is STI-negative, double-confirmed last week. Real shoot time: 8–14 hours or longer; edit will condense it. Strip now."

Clothes hit the floor in a cascade.

• 300 cocks exposed to the air — thick veiny shafts, long curved ones, average twitching with nerves, some still soft from sheer terror
• Opposite them, 300 pussies revealed — some already puffy and dripping, others shyly closed, natural bushes framing glistening wetness

Several men tremble visibly. Virgins stare wide-eyed at the sea of breasts and mounds, knees weak, breathing shallow.

One voluptuous MILF spots a particularly shaky virgin nearby. She saunters over, hips swaying, and whispers in a low smoky voice:

"First time, huh? You lead… but give it real effort. Satisfy me, and I'll give you an orgasm you'll never forget."

The four pros — already oiled and hard — spread out.

• One kneels to slowly circle a rookie's clit with his tongue for demonstration
• Another takes a newbie's hand, guides it to a MILF's soaked entrance: "Feel how wet she is… slide in slow, grind upward like this…"

The hangar air grows heavier — coconut lube, sweat, precum, feminine musk, fear-laced excitement all mingling.

The director raises his hand. Lights blaze full intensity. Dozens of red camera tally lights snap on.

"Rolling… three… two… one…"

Six hundred naked bodies surge together. Skin slaps skin, moans erupt, mattresses creak under sudden weight.

The longest, dirtiest, most unhinged night in AV history has begun.

What happens next remains to be seen.
