... the physical

Mackenzie and her guard stopped in front of another door. The guard knocked and the answer was prompt. "Enter!" she heard from inside and Mackenzie was led into a windowless but well-lit room, immaculate and furnished sparingly: a desk, an examination table, and an examination chair. A nurse dressed in white scrubs was sitting at the desk, working something on her computer. "New inmate for her physical." said the guard.

"Alright, put her on the chair. I'll be right there" answered the nurse while pulling a pair of latex gloves. Mackenzie was put on the examination chair, where her hands were unshackled again and restrained her with tight straps. The examination started very routine, like a regular physical. "So far so good. Lift her feet up." said the nurse again, making a few notes in her book. The guard lifted the chair's stirrups and reclined it, so Mackenzie was **** to lie on her back with her legs lifted and spread, while the guard restrained them too.

The nurse squirted something on her gloved fingers. Seconds later, Mackenzie felt her labia parting and the nurse's index and middle finger entering her. The redhead felt overtaken by a deep sense humiliation, but also, to her embarrassment, arousal. She tried to say something, but a quick glance at the guard, with her hand on the stun gun, kept her silent. Mackenzie moaned instead, as her pussy became more and more wet and the nurse began moving her fingers in a rapid, pumping motion. "Oh my fucking god ..." Mackenzie felt like she was irreversibly heading toward an orgasm, but the nurse stopped suddenly and pulled out her fingers, taking a few notes. The sudden stop and the sense of emptiness left the redhead wistful and needing more.

The feeling of emptiness didn't last long. Another soft squirt and Mackenzie felt a dull pressure against her anus, which turned a little sharp as the nurse's index opened her sphincter. "Try to relax. This is not gonna hurt much." said the nurse. "You should be already loosened up a little from the enema." The nurse pushed her lubed finger inside of her completely, sliding in while her muscles tightened and relaxed involuntarily. Mackenzie's history of butt play was limited - one of her exes had talked her into it and the experience had put her off completely - but now she felt full, pleasurably full. She felt even more humiliated and aroused now, and gasped again loudly as the nurse moved her finger in and out with gradually increasing speed, her arousal building up quickly before the nurse stopped abruptly and removed her finger again.

"OK, done here." The nurse took off her gloves and threw them in a garbage bin. She looked at her notes and wrote down something on her computer, while the guard let her go off the chair and handcuffed her again. Mackenzie arched her back a little bit, the memory of the nurse's finger and the sensation of fullness lingering as she was led outside the room, to her next destination.
