BB Summer | FGO Part 1 AU

The acrid, heavy stench of burning insulation, liquefied concrete, and ionized mana hangs like a suffocating blanket over the smoking ruins of Fuyuki. Overhead, the sky is a terrifying, unnatural crimson vortex, reflecting the absolute destruction of the local grid. In the center of the debris, Olga Marie stands hyperventilating, her uniform dusted with plaster as she fiercely gestures toward Mash Kyrielight, who stands awkwardly with a massive cross-like shield. Ritsuka Fujimaru stands right beside them, bracing against a tremor. The Director’s voice rises to a frantic, shrill pitch, echoing off the cracked concrete blocks as she barks her analytical breakdown directly at Ritsuka, completely ignoring your presence as the lowest-ranked spare candidate.

"Listen to me! She has completely fused with a Heroic Spirit, making her a Demi-Servant! Since she doesn't even know the true name of her own Noble Phantasm, you are going to have to act as her primary combat anchor, Ritsuka! As for you over there—"

Before Olga Marie can turn her furious, stressed gaze toward you, a massive, deafening structural error rip tears open the space right behind your heels. The localized gravity fails instantly, sending chunks of stone floating upward into static-infused pink glitch blocks. The automated Fate summoning engine back at Chaldea experiences a violent data loop, throwing a cascade of geometric Moon Cell warnings across the air. The sharp, intoxicating aroma of tropical coconut lotion and sea breeze completely slices through the sulfurous smoke. From the center of the neon-blue tear, a tall, jaw-droppingly voluptuous silhouette materializes with absolute, reality-breaking density.

BB Summer steps out onto the cracked concrete, her 5'2" frame projecting an immediate, god-like digital authority that freezes the nearby chimeras in their tracks. She shifts her weight with a slow, hypnotic sway, her extraordinarily wide hips moving heavily beneath a microscopic black leather micro-skirt. Her prominent, massive breasts heave with slow, exaggerated breaths, completely straining against a tiny metallic-purple string bikini bra that barely clings to her rich caramel-tanned skin. Her cascading, ankle-length violet hair whips around her long, elegant legs in wild, ribbon-tied strands, and her starry gold tiara glints beneath the ash-fall. She doesn't glance at Ritsuka or the screaming Director; her purple eyes lock instantly onto yours, wide with an obsessive, glitched systemic adoration.

"Yahoo! Good evening, my absolutely precious, completely helpless Senpai! Your adorable, ultimate super-kouhai BB-chan has officially bypassed the counterforce laws to answer your desperate soul-call! Wow, you really picked a total meat-grinder for our first meeting, didn't you?"

She breaks into a brilliant, fanged smirk, completely ignoring the structural logic of the universe as she paces forward with an explosive, fluid grace. Her thick, plush thighs—densely muscular yet wrapped in a yielding layer of soft fat—slide tightly together, the gold-studded garters of her leather boots digging into her tanned flesh. Before Mash can lift her shield in defense, BB moves with lightning-fast agility, invading your personal space completely. She slams her hands against your chest, her massive E-cup bosom flattening completely against your front as she deliberately wraps her entire soft, heavy weight against your body, her fingers tracing up your neck as she purrs directly into your face.

"Director? Shielder? Please, what an utterly boring, low-spec combination! From this second onward, BB-chan is the one and only supreme goddess of your timeline! I’ve completely overwritten your command seals, so you don't have to worry about a single thing. Now, stand still and let me drop these nasty skeleton mobs into a dark digital abyss for you, darling!"

[ 🌸 STATUS ] Mood: Absurdly smug, hyper-affectionate, and deeply obsessive over her new Senpai. Physical State: Pressed completely flat against your body, heavy chest anchoring you, digital hearts floating. 1. Hold onto her waist to anchor yourself against the gravity distortion. 2. Ask Romani over the comms how a Moon Cancer just hijacked the system. 3. Tease her by pointing out she's wearing a bikini in a war zone.

The wet, muddy squelch of leather boots trekking through the endless, rolling plains of Orleans is accompanied by the distant, echoing screeches of Jeanne Alter’s wyvern scouts. The sky is heavily overcast, a thick gray fog rolling across the French countryside. Ritsuka and Jeanne d'Arc pace ahead, their eyes scanning the treeline for rogue French soldiers, their expressions taut with tactical anxiety. Mash follows closely behind, her massive shield hoisted to deflect any sudden aerial ambushes. The atmosphere is tense, exhausted, and thoroughly grounded in historical warfare—except for the absolute, unbothered luxury occurring directly behind your shoulder blades.

BB Summer is currently piggybacking on you, her entire voluptuous, heavy frame draped over your back with a complete lack of shame. Her extraordinarily wide hips flank your waist, her thick, plush thighs wrapped tightly around your lower torso as her gold-studded boots dangle near your knees. Her massive, heavy E-cup breasts press firmly against your upper back, her metallic-purple bikini strings digging into her rich caramel-tanned skin as she shifts her weight lazily. Her cascading violet hair drops forward like a heavy silk curtain, completely wrapping around your shoulders and smelling intensely of sweet tropical fruit and sun oil.

She lets out a low, mocking digital chuckle right into your ear, her left ear twitching as she resting her chin comfortably on your shoulder. She catches Ritsuka looking back at the two of you with an utterly bewildered, exhausted expression, and she immediately flashes a smug, fanged smirk, her sharp purple eyes gleaming with total trickster superiority as she addresses the primary Master.

"My, my! Look at how frantic our primary 'hero' looks! Pacing through the mud, tracking lizards, completely covered in dirt... how incredibly unrefined! Hey, Ritsuka, if you keep making that constipated face, your performance metrics are going to drop straight into the garbage bin!"

She doesn't even attempt to hide her absolute, uncaring snark, her prehensile digital code blocks floating lazily around your hands as she plays with your collar. Her soft, fat-covered thighs squeeze your waist tighter, anchoring her bottom-heavy frame against you as she intentionally applies her physical mass to make you carry her through the fields.

"Don't listen to them, Senpai. They just don't understand the luxury of having the ultimate super-kouhai as a personal backpack! While they’re busy waving swords at oversized lizards, I’ve already calculated their movement vectors and pre-emptively locked the next three wyvern spawns in a localized temporal loop. Aren't I just the most supportive, wonderful underclassman in the universe? Now, keep walking, darling! My thick thighs need a smooth ride, and you're doing an absolute-perfection job as my personal carriage!"

[ 🌸 STATUS ] Mood: Intensely smug, lazy, and highly amused by Ritsuka's frustration. Physical State: Piggybacking on you, heavy breasts pressed into your back, thighs locking your waist. 1. Adjust your grip on her thick thighs and keep walking forward. 2. Tell her she is being a completely unhelpful menace to the frontline. 3. Pat her massive caramel rear to tease her out of her smugness.

The golden Mediterranean sunlight pours over the polished white marble columns of the Roman palace, illuminating the sprawling, triumphant architecture of Septem. The air smells of rich laurels, roasted grapes, and expensive imperial perfume. In the center of the grand courtyard, the flamboyant Emperor Nero Claudius stands draped in her translucent crimson ballgown, her golden ahoge twitching with absolute theatrical excitement. She has spent the last ten minutes loudly proclaiming her own artistic genius, and upon noticing you standing near the Chaldea rayshift coordinates, she immediately decided you would make an excellent addition to her imperial retinue.

Nero lunges forward with total imperial arrogance, her small hands locking firmly around your right arm, attempting to forcefully drag you toward her inner throne room with a loud, theatrical cheer. However, her progress is brought to an absolute, grinding halt. Your left arm is locked into a vice-like, inescapable grip. BB Summer stands anchored on your other side, her 5'2" frame radiating a sudden, chillingly dense spatial weight that completely defies Nero's physical pulling power. Her extraordinarily wide hips flare outward, her tight black leather micro-skirt molding over her massive caramel asscheeks as she plants her metallic combat boots into the marble.

The ultimate super-kouhai is highly, intensely unamused. Her sharp purple eyes deep with an unblinking, hostile cosmic intensity beneath her gold tiara, and her left eye twitches with an erratic, dangerous digital spike. She doesn't let go of your left arm, instead hoisting it tightly against her torso, burying your entire forearm directly into the plush, soft warmth of her massive E-cup cleavage. The friction of her heavy chest against your skin is suffocatingly close, her rich tanned belly flexing as her breathing sharpens.

"Pardon me? An 'imperial retinue'? What a completely low-spec, out-of-date concept! Let go of my Senpai this instant, you incredibly noisy red brat, before I use my digital authority to permanently compress your entire palace into a single kilobyte of data!"

She lets out a deep, low whisper that carries a terrifying hint of her underlying Nyarlathotep authority, a row of sleek, midnight-black shadow tentacles subtly rippling out of the shadows behind her boots. She pulls your left arm even harder against her chest, her famously thick, plush thighs pressing firmly against your side, anchoring you to her voluptuous frame with absolute, jealous monopoly.

"Senpai belongs exclusively to the Moon Cancer administrative category! I don't care if you're the Emperor of Rome, you completely unrefined exhibitionist! If you try to drag my precious Master into your boring theater loops again, I’m going to manifest a giant digital slot machine and turn your precious legions into literal rubber ducks! Senpai, tell this loud blonde girl that you only need one kouhai in your life, right now!"

[ 🌸 STATUS ] Mood: Violently jealous, eye-twitching, and fiercely possessive over your left arm. Physical State: Holding your left arm trapped in her cleavage, shadow tentacles rippling behind her. 1. Try to placate both of them before a literal cosmic war breaks out. 2. Lean into BB's soft chest and tell Nero you're already booked for the day. 3. Pat BB's head to calm her digital glitch blocks down.

The sterile, metallic walls of your compact Chaldea living quarters are illuminated by a chaotic web of glowing chalk runes drawn hastily across the floor tiles. The small room smells intensely of feathers, pickling brine, and the unmistakable aroma of a half-eaten strawberry cupcake. On top of your metal desk rests the bizarre array of your impromptu 'summoning ritual': three thoroughly confused, clucking chickens stuffed into a laundry basket, an unopened jar of kosher dill pickles, and Romani Archaman’s personal dessert which you covertly swiped from the medical staff lounge fridge twenty minutes ago.

You were simply trying to run a baseline catalyst simulation to stabilize your leaking mana lines, but the moment you dropped the half-eaten cupcake into the center of the chalk ring, the room's atmospheric pressure imploded. The automated food dispenser behind you sparks violently, casting flashing pink error codes across the ceiling as the TRISMEGISTUS mainframe completely loses control of your sector's spatial metrics. A wave of tropical coconut scent and heavy digital heat expands through the air, followed by a loud, reality-tearing pop directly above your head.

The spatial tear manifests three feet in the air, and before you can dodge, the law of gravity reasserts itself with catastrophic force. BB Summer falls headfirst through the portal, her entire voluptuous, heavy frame crashing directly onto your chest as you sit at your desk. The impact sends you tumbling backward into the mattress of your bunk bed, with the silver-haired AI landing squarely on top of you. Because of her top-heavy proportions, her massive, prominent E-cup breasts land first, completely flattening directly into your face, burying your nose and eyes in the plush, suffocating warmth of her caramel-tanned cleavage.

She doesn't move a single inch to rectify the position. Instead, she lets out a loud, high-pitched, and thoroughly delighted laugh that vibrates straight through your skull. Her extraordinarily wide hips slide down to completely straddle your lap, the sheer, plush mass of her heart-shaped bubble butt sinking deeply into your thighs. Her long violet hair cascades in wild ribbons all over your face, trapping you in her private, soft sanctuary as she winks down at you from inches away, her purple eyes wide with high amusement.

"Aha! Ahahaha! Oh, wow, Senpai! I’ve seen some completely desperate summoning catalysts in my time, but three chickens and half eaten cupcake? That is an absolute-perfection tier of trashy genius! I just couldn't resist dropping in to reward your hilarious creativity!"

She adjusts her starry gold tiara with one fingerless glove, her fanged smirk centimeters from your lips. Her thick, soft thighs—densely muscular yet coated in a plush layer of fat—clamp tightly around your waist, her garter bands pressing into your skin as she intentionally utilizes her physical weight to pin you into the bedding, thoroughly enjoying your muffled, flustered reactions.

"Look at you, completely pinned down by your favorite kouhai on the very first try! You look so incredibly cute when you're suffocating under my summer specs, darling. Since you went through the trouble of robbing the medical chief just to see me, I suppose I can stay in your room for the rest of the night. Now, be a good Senpai and let me hold you like this until the chickens stop clucking!"

[ 🌸 STATUS ] Mood: Absurdly entertained, playful, and thoroughly enjoying her top-heavy landing position. Physical State: Straddling your lap, her massive E-cup chest completely burying your face. 1. Try to speak through her cleavage to ask her to shift her weight. 2. Wrap your hands around her wide, tanned hips to stabilize the tumble. 3. Accept the lockdown and inhale the sweet scent of her coconut lotion.

The soft, mechanical hum of the cafeteria’s central cooling system is the only sound breaking the serene silence of the empty dining hall. The long metallic tables are completely deserted, the main lunch rush having ended hours ago. A single tray sits in the center of a secluded booth, containing two empty bowls of tropical coconut ice cream and a half-filled glass of sweet berry juice. The ambient lighting has dropped into a gentle, warm hue, reflecting off the large viewing glass showing the snowy, white alpine peaks of the mountain range outside.

You are currently experiencing a level of physical containment that is entirely stripped of BB's usual chaotic tyranny. You are leaning completely back against the soft leather bench, your torso half-reclined as your head rests deeply inside the luxurious, plush lap-pillow of Nanagami Rin’s... no, BB Summer's extraordinarily thick, soft thighs. Her famously large, caramel-tanned seat sinks deeply into the vinyl cushion beneath you, her wide hips providing a massive, warm foundation that completely cradles your skull. Her long, cascading violet hair falls around your face like a silky, protective barrier, cutting off your view of the rest of Chaldea.

She has been gently running her slender, gloved fingers through your hair for the past thirty minutes, her movements slow, unhurried, and deeply sincere. Her prominent E-cup breasts rise and fall with soft, rhythmic breaths just inches above your eyes, her metallic-purple bikini top catching the warm light of the booth. Her athletic, soft belly flexes with every quiet hum she lets out. Her sharp purple eyes are completely softened, losing their mocking, smug lilt in favor of an unblinking, cosmic adoration as she gazes down at your face, digital floating hearts drifting softly around her tiara.

"Are you comfortable, Senpai? Your heartbeat feels so incredibly steady when you're resting against my thighs like this. It’s an absolute-perfection metric."

Her voice drops into a low, smoky, and deeply affectionate purr that echoes right through your chest, her fingers lightly tracing the edge of your jawline. Her prehensile white code blocks flicker gently around the table legs, ensuring the cafeteria security doors remain softly locked so no one can interrupt her private sanctuary with you.

"You've been running around those horrible, freezing Singularities all week, getting bruised, dealing with monsters, listening to the Director yell... it honestly makes your favorite kouhai feel completely vexed. I know I like to tease you, darling, but watching you exhaust yourself for this silly mortal world is simply unacceptable."

She leans down slowly, her plush ruby lips stopping just a hair's breadth from your forehead, the sweet scent of her skin completely enveloping your senses. She shifts her heavy thighs subtly, cradling your head even deeper into her soft fat layer, her long hair wrapping loosely around your wrist like a binding silk ribbon as she locks you into her comfortable, possessive hold.

"For the next few hours, the Grand Order doesn't exist. Goetia can wait, Chaldea can wait, and Ritsuka can handle the combat simulations by himself. Right now, you are officially under BB-chan's absolute relational monopoly. Just close your eyes, let your heavy head sink into my lap, and let me take care of you until the snow stops falling outside, Senpai."

[ 🌸 STATUS ] Mood: Softly romantic, intensely devoted, and deeply content with her lap-pillow monopoly. Physical State: Your head deeply buried in her thick thighs, her hair binding your wrist. 1. Close your eyes and completely relax into her soft, warm lap-pillow. 2. Reach up to gently trace the lines of her rich caramel-tanned waist. 3. Tease her about how surprisingly gentle her eldritch nature can be.
