Write an intense 5,000-word explicit smut story. Each part in the story should have at least one climax for each character, and the physical steps leading to each climax should be fully detailed. A story origin can be included to deepen the story. Additional sensory details, such as taste, scent, or sound, can also be included.

The summary or keywords to base the full story on:
The story starts with a man clipping out of reality and ending up in the backrooms, and begins exploring to try to find his way out. Detail what he finds along the way, and what entities he encounters. The twist is the entities are feminine versions of the backrooms entities found based on his current location within the backrooms, only use entities from the backrooms lore, do not create new ones. The entities are altered to be erotic and with the desire to mate with the man or pleasure him by force, use the entities unique appearance and abilities to describe how the sexual encounter plays out, as the entity might not have a vagina or mouth, so you will need to get creative, though any orifice on the entities should be a pussy or a mouth. After the sexual encounter the man continues his exploring of the backrooms. To keep the story flowing, only have one entity per location, and there might be several encounters with the entity before it catches him, with at least one sexual encounter with the entity, and the entity makes the man cum before the encounter ends. The entities should be just as dangerous and terrifying as their counterparts, after the sexual encounter the man must escape the entity, or suffer the same fate the normal entity would bring upon him. The man CAN die, if this happens, the story continues with a new male in a different location within the backrooms. Title each part with the current backrooms location.

Suggestions:
- Keep track of everyone's physical location, sex act, sex positions, the type of clothing and state of their clothing, think through each scene in a step by step way to make sure the story makes sense and is physically possible.
- Suggest a specific location or backdrop, like a dark alley, onsen, pool, hot spring, classroom, public location, a palace room or a specific location based on the story summary, to help contextualize the encounter.
- Incorporate specific sex acts and kinks that include teasing and non-penetrative sex like thigh jobs, hand jobs, boob jobs before moving on to penetrative sex acts, like vaginal penetration, leg locks, and different types of oral sex, ending with cum in pussy, cum in mouth or cum on body. Take the selected females personality and behavior as a big factor.
- Always use explicitly detailed descriptions of the sexual anatomy and sexual acts performed for every sexual encounter in the story, never summarize the sex, and never use suggestive language or innuendo.

Write only one part at a time, split the story up into appropriate chunks with one sex scene per part, focus on going into full detail of that part, and only that part, taking the time to describe the sexual interactions in detail, stop at the end of every part and ask for me to confirm the continuation of the story, and we keep going until I say to stop.
