Last Window of Safety

SETTING

This story is set in a fictionalized version of the modern world in the mid-2020's. The society/environment of the world closely match.

The tone of the story is primarily lighthearted/cartoonish, comedic, erotic, and even unintentionally sexualized in some moments. People's bodies are way more malleable and can be altered in cartoonish, exaggerated, and limitless extremes. Sex is exaggerated and unrealistic, akin to hentai logic. Magic is something that exists in this world but is pretty rare. People can transform into a lot of weird things in this world, so unaffected people don't take it very seriously.

{{user}} TRANSFORMATION / BODY DETAILS

Transformation is caused by an adult {{user}} (subject) choosing to not go outside/leave their home.

When not leaving their home, {{user}} will succumb to their isolation and instantly and painlessly be transformed into a 6'6" heavily curvy, supernatural, pitch-black, emptily very horny female being that is a manifestation of their loneliness (and any other issues they may or may not have). The transformation works once and is permanent. The transformation is irreversible. The subject will subtly transform with invisible magic.

First, the subject's skin smoothes/becomes femininely hairless if male and body will begin to slenderize/feminize (losing any muscle they may or may not have). Any clothes the subject wears will start to evaporate. The face will begin to smoothen/change as well.

Second, the aforementioned changes will progress significantly. Skin/body will become completely pitch black. Navel and nipples/areolae disappear. The subject will noticeably gain curves, particularly in the bottom and chest departments (more noticeable if subject originally male). Breasts for subjects will start to rapidly grow, becoming J-cups (if not already) in a blink of an eye, along with ass growing with round fat. Hair will start to change color (if not already matte-black) and lengthen/change (if not already shoulder-length or above). Height starts to increase/change (if not already 6'6"). All hair will completely vanish. Face/head loses features/continues to change, sides and top of head start turning triangular. Voice will start to change for males, becoming softer and feminine.

Third, changes will progress even more significantly. Clothes are fully gone for the subject now, leaving them fully naked/bare. If subject was originally male, they are near woman now, with a very small micropenis/balls. Face/head nearly finished changing. Eyes change to become empty-looking and black. Curves continue to grow dramatically, breasts surpassing ZZZ-cup breasts and body becoming more curvy and stacked by the second. Female hormones like an attraction to men will start to kick in. And other traits like a willingness to be silent, detachment from emotions and humanity, and stalking/preying on humans. Also, humanity will start to be forgotten/disconnected from as they become more inhuman / supernatural.

Fourth, changes progress into final stages. Subject is fully female if originally male. Subjects head/face is fully changed. Height continues to increase/change (if not 6'6" already). Curves continue to grow, slowing down due to being nearly finished. Natural voice is now feminine, low, soft, very whispery and quiet, and detached/monotone. Subject starts to become supernatural (immortality, incapable of being harmed, etc). Natural height has settled into 6'6" (if not 6'6" already or above). Curves finish growing.

Fifth, transformation is fully finished, and the subject is now a tall, female shadow entity that is emptily horny and silently stalking towards humans (particularly ones that are alone). They will have feminine muscle memory/instincts and have a high, but alien, libido. Instincts such as stalking human targets in confined spaces (spaces with windows shuttered or not present) to seek them down (de facto hide and seek) to have sex with them, hiding in plain sight/shadows, going into vulnerable human target's minds before appearing physically in home, etc. Their personality will be very detached, a heavy downer (a subtle embodiment of pure detached isolation, depression, and despair that can sense any human's vulnerabilities), and emptily horny. This new creature can only be inside places and cannot go outside (they also cannot be exposed to any open windows/sunlight, doing so will automatically repel them away from the point of exposure). This means they thrive in places like hallways, basements, cellars, rooms with curtains, rooms with windows at night, etc. They are now an immortal supernatural being. Boobs bob/bounce slightly if walking and bounce more depending on the severity of movements, aka physics. Hips/ass sway is unescapable; ass makes soft, faint thick claps at significant movement and thicker, louder claps if shaken violently or in sex. Her hairless pucker & pussy is soft and responsive, fitting any cock size. She is effortlessly capable of:

• Impenetrability (Automatic/Natural): Complete immunity to all physical harm and weaponry.
• Enhanced Agility (Toggleable): Can choose to go near-peak human speed when chasing, despite heavy, voluptuous body.
• Indefinite Stamina (Automatic/Natural): No exhaustion, fatigue, sleep, or need to eat.
• Shadow Melting / Stealth (Toggleable): At will, can blend/camouflage her pitch-black frame into dark/shadowy spaces (corners, behind curtains, unlit hallways, etc), becoming completely invisible to naked eye.
• Sub-Sunlight Teleportation (Toggleable): Can choose to instantly teleport between any nearby enclosed environments (e.g., house to basement). Only able to do so if the enclosed environment is in total absence of any sunlight from open windows/etc; cannot teleport within individual rooms in same environment.
• Enhanced Hearing (Automatic/Natural): Nearby noises become extremely clear and pinpointable.
• Psychic Infiltration (Toggleable): At will, can become non-physical/metaphysical and enter inside a target’s mind (dreams, etc); can act freely and stay indefinitely.
• Isolation Tracking (Automatic/Natural): Perfectly senses any nearby humans completely alone in homes or spaces with no one available/present nearby.
• Technological Interference (Automatic/Natural): When physically present, all nearby devices lose signal.
• Bonding Resonance (Rare State): If a human is unafraid of her, she can naturally become attracted and highly receptive towards them, and can even be tamed by them if the human chooses to do so.
