Serena had heard about this place from a trusted girlfriend; during a long and tipsy happy hour, the friend had described this place as a "sex fantasy amusement park/spa." Her friend had given her a simple business card, with only a phone number on it. Serena brushed it off at the time, but after several weeks of wondering, she caved and gave the number a call.
Now she found herself sitting in a simple, yet fancy modern office. Across the desk from her was a calm, professional woman named Elizabeth, explaining all the paperwork and answering her questions. Elizabeth had given her a list of sexual situations, kinks and fantasies to look through. The idea was that each guest would craft a personal fantasy they'd like to live out, and for a hefty fee the establishment would create that "Experience" for them.
Serena browsed through the suggestions, and one of the menu items jumped out at her immediately - it was something she was always curious about, but never wanted to bring up with an actual partner. She quickly checked off some boxes, before she lost her nerve, and handed the form back to Elizabeth. Elizabeth looked over it and smiled, saying, "Wonderful, I'll just need you to sign here and we can begin the experience."

Serena wakes up slowly, she feels a little groggy, and it takes a few moments for her to blink her eyes open. She is lying down on her back, above her is a gray concrete ceiling. Serena tries to to rub her eyes with her hand, but she finds that they are bound together and secured above her head. She quickly looks down the length of her body to assess what else might be bound. She finds that her feet are also strapped down, each ankle is secured and spread slightly apart, resting next to the edges of the surface she is lying on. Serena can only lift her head so high, but it seems she is lying on a flat table, it has some padding and reminds her of the exam table at a doctors office, but longer to accommodate her full length. Serena is happy to find that she is somewhat clothed, wearing a hospital gown-like garment.
Looking around, it seems like Serena is alone in the room, at least for the moment. It's a reasonable sized room, but it feels larger due to it's cold and industrial nature. There are fluorescent lights, gray concrete floors and drab walls. Around the room are various cabinets and mysterious looking equipment, along with a small seating area. The oddest part is what looks like a large, caged-off area in the corner.
As she's looking at the cage, Serena here's a door open on the other side of the room. She whips her head in that direction and sees two men entering. Both are handsome and stoic, but one is clearly the leader due to his more mature age and general sense of confidence. Serena feels a shiver of hesitation, wondering what she has gotten herself into; here she is completely bound and barely clothed, apparently at the mercy of two complete strangers. The two men walk towards her and look her over with their eyes; Serena feels incredibly self conscious, but she cannot move any part of her body to hide.
The older man says, "Hello Serena, you may address me as the Doctor, and this is my assistant."
Serena nods, unsure if she should speak or not.
"We will begin your experience with an examination," says the Doctor, who gives a slight nod to his partner.
The Assistant takes action and wheels over a cart that has a multitude of implements on it. The Doctor starts with simple tasks, like taking her blood pressure and listening to her breaths with a stethoscope. Serena shivers with each touch, not yet used to this stranger's hands. Without much warning, the Doctor slides his hand under the collar of Serena's gown, and places his hand on her breast. Serena's pulse quickens as he deftly examines her breast through touch. He removes his hand and moves down the table, this time he gently lifts the hem of her gown, and folds it over, exposing her from the ribcage down.
Serena pulls in a sharp breath; a quick peek confirms what she suspected, that she has no underwear on. The Doctor and the Assistant can both see her completely exposed vagina. The Doctor places his hands gently on her abdomen and applies pressure, moving his hands this way and that. The Assistant is holding a small bottle out towards the Doctor, anticipating his next step. After applying a small amount of lube, The Doctor swiftly enters Serena with two fingers. She gasps at the sudden intrusion, but the Doctor stays stoic faced as usual. He moves around, clinically assessing her vagina. Before Serena can even get comfortable, he is back out and nodding to the Assistant.
Each of the men unstrap one of Serena's ankles, and the Assistant moves to take both of them in his hands. He holds her ankles shoulder width apart, and raises Serena's legs up straight up. This leaves not only Serena's vagina exposed, but also her asshole. The Doctor busies himself at the cart and when he turns around Serena's eyes go wide; in his hand is a butt plug, something she has never used before. The Doctor walks over and Serena starts squirming; the Assistant strengthens his grip on her and pins her down further.
Once again, the Doctor applies lube to his fingers and slowly starts tracing around Serena's asshole. At first Serena is very tense, but soon she finds herself enjoying the sensation and relaxes. The Doctor presses the tip of his finger up against her hole, and slowly pushes in. Serena's muscles instinctually resist, but the Doctor keeps pushing, eventually inserting his entire finger. Slowly, he moves around and around, in and out, stretching and loosening Serena's asshole. Once satisfied, he removes his finger and grabs the butt plug.
Placing it against Serena's opening, he slowly pushes it in. Serena gasps, it's not huge but it is certainly bigger than a finger. The widest part slides past her opening and she can feel the flat bottom coming to a stop against the outside of her asshole. She clenches a few times, eventually getting used to the sensation.
The Assistant brings her ankles together and lifts upwards, raising Serena's bottom off the table and surprising her. She hears a crinkling noise and looks over to see the Doctor with an adult diaper in his hands. Serena's eyes widen, not sure if she's ready for this. The Doctor unfolds the diaper and slips it under Serena's hips. She certainly feels like a baby, with one man holding her up by her ankles and the other putting a diaper on her.
