Mina took off her lab coat and switched her bifocals for goggles, donning very long latex gloves and rubbing some kind of liquid on herself. “Stay as still as you can” Mina said as she easily spread the large cheeks of her patient, taking Marina by surprise. Mina started by feeing inside the rim of her anus, teasingly circling it, making Marina shudder at the cold touch. Then she went deeper, fisting the skunk’s large but tight hole, making Marina moan in pleasure. All of the sudden, she felt something getting shoved into her, something large, something moving. Mina was inside her ass, crawling through her lower intestines like a snake. Marina’s cock had never been so erect from anything she’d done to herself, she felt like she could cum at any moment. She felt pressure building in her gut, so she felt like she had to let another of her signature farts go, but she was a little hesitant with the small girl inside her. Mina poked at something inside her and she lost all control. A set of 20 second chainsaw farts erupted out of the fat skunk, setting her over her limit as she once again jizzed while farting. She painted an entire wall with her cum, while the other side was basically dead space. Marina was in so much bliss that she fell face first onto the ground, exhausted from her emissions. A few seconds later, the resident reappeared out of her asshole, but looked quite different. She had claws, gigantic ears, a long, slender tail, and a tiny snout.

Lifting her head, she barely managed to make out the top of Mina’s ears as they moved from screen to machine to another screen. Marina made some audible grunt (not awake enough to make a sentence) that caught Mina’s attention, so she slowly got into Marina’s view. Once in view, Marina realized that she never cleaned herself off after going into her ass, she smelled just like her. She should’ve been put off by it, but it just left her amazed. Mina finally spoke up, “So my patient is finally awake, good to see your producing a healthy amount of stink, your anal cavity is actually pretty clean, no sign of growths or residue, you must purge your system regularly. I must applaud you for that. I’m running some machines to monitor your vitals and making sure that nothing abnormal happens when you skunk out. It may be necessary to run other test by I will only do them with your consent. As for now, just rest, we have much to do and very little time to do it all.” Marina just had to stare at her, she didn’t catch everything that was said, so the only thing she could get out was, “How are you not dead?” before basically pulling back into unconsciousness. Mina whispered to her, “All in due time, my favorite patient, all in due time.” Mina prepared another device to...
