I developed this series idea inspired by a short tale titled The Thing From Within the Drain (https://forum.hentaied.com/index.php?threads/kelsy-in-distress.1985/#post-5537). Building on that concept, the series unfolds across six interconnected episodes, each exploring the terrifying creature that lurks within the gym’s hidden spaces and the dark, complicit bond it forms with Erika de Vianté, the gym’s enigmatic owner.
This series follows a bizarre and unsettling creature, known only as The Thing, that grew up within the hidden pipes and vents of a gym. Its body is tubular, with writhing tentacles surrounding a gaping mouth. The creature attacks its victims by teasing and stimulating them until they lose resistance, overwhelmed by unnatural pleasure. At the height of climax, the tentacles release a fluid that covers the victim—after which the creature devours them whole.

Based on The Thing from Within the Drain, this episode introduces Kelsi, a dancer and digital influencer. Kelsi is a blonde bombshell known for her sultry workout and dance videos. One night, she convinces Erika to let her use the gym after hours, arguing that her large following is good publicity.
With Erika in her office and the weary receptionist Maria at the front desk, Kelsi heads for a relaxing shower. There, she has a surreal encounter with something lurking in the drain—something with hungry, searching tentacles.

Weeks after Kelsi Summers’s disappearance, Maria has quit her job. In her place works Vika, a sassy and charming brunette with a sculpted body. Confident and seductive, Vika treats the job as a temporary stop to cover her college bills, supplementing her income by filming adult videos with her boyfriend.
After hours, she sneaks into the tanning booth to prepare for her next shoot. But as the machine hums, the creature emerges—not from the drain this time, but from the vents—giving Vika an unforgettable fate.
This is the first episode that hints Erika might know more about the creature than she admits.

Erika personally assists Lily, a flexible and graceful young woman of Asian descent, with her stretching routine. Afterward, Lily asks for a massage, but the masseur is off-duty, and her appointment hadn’t been booked in advance. Not wanting to disappoint a good customer, Erika offers to perform the massage herself.
In the softly lit massage room—candles glowing, incense curling—Erika begins. But when she steps out briefly to speak with her secretary, Lily is left alone. The creature seizes the chance, slipping from the vent. At first, Lily mistakes the touch for some innovative technique… until she realizes she is surrounded by tentacles.
By the end, as the monster withdraws back into the vent, Lily is gone—and Erika, returning to the room, carefully removes every trace of what occurred.

Sofia, Erika’s secretary, manages the gym’s paperwork and discreetly erases traces of the disappearances. A curvy Latina, pragmatic, and unquestioning, Sofia is useful—but one day, she nearly exposes Erika’s secret by forgetting to delete compromising security footage.
Furious, Erika punishes Sofia not by firing her, but by delivering a harsh spanking. When she notices Sofia actually seems to enjoy it, Erika decides to take things further. She binds Sofia and presents her as both plaything and offering to her monstrous ally.

A new client arrives one evening—Alex, a cunning journalist eager to move beyond glossy magazine work. Alex suspects a connection between the gym and the string of missing women. Her theory points first to a male customer, but the lack of footage suggests a more sinister cover-up.
Feigning cooperation, Erika leads Alex to the basement, claiming she has a lead. There, Erika seduces her. Just as Alex yields, the creature emerges, drawn to the heat of the encounter. It overwhelms Alex while Erika looks on in ecstasy.

With police closing in on the investigation, Erika senses her time is running out. Late at night, she returns to the gym one last time. There, the creature—now massive from its many meals—crawls toward her.
Erika confesses her obsession: ever since she first witnessed the monster devouring Kelsi, she has been entranced by its dark allure. Each new disappearance only deepened her desire.
As the moment of truth arrives, Erika accepts the only fitting end—offering herself to the creature, body and soul, in a final act of twisted ecstasy before being consumed.
