Sakura's Enema Training, Part 1
Content warning: this story contains graphical description of rape and scat.
Sakura entered the nurse's office of the Academy, and was surprised to see Shizune waiting for her. Today, she was scheduled to have a practical lesson with Tsunade and a patient, but neither of them were present.
"Afternoon, Sakura. And no, your lesson for today isn't cancelled. Something urgent came up for Tsunade so I'm here instead, and the patient who was supposed to be treated today said she was feeling better and cancelled."
"So that's how it is. But I'm supposed to practice giving enemas today. If there isn't a patient, how am I supposed to practice?"
"You'll be giving me the enemas," Shizune said, smiling gently. "I've had an awful stomach ache since this morning." That was a lie, but she was banking on Sakura to buy it. The truth was, Shizune had an extreme enema fetish. Just the thought of being on the receiving end of one made her wet, so the moment she learned from Tsunade that the constipated patient had bailed, taking her place was the obvious choice.
Shizune closed the window curtains and walked past Sakura to lock the door. "Just so you know, I'll be giving you an enema first, to show you how it's done."
Sakura tensed up. "… can I not, Shizune?"
"I'm afraid you don't have a choice. Tsunade gave the order, and there are good reasons for it. For starters, one of the most basic principles of being a doctor is that you mustn't do anything to a patient that you wouldn't do yourself. If you can't give yourself an enema, how can your patients come to trust you?"
"Right…"
"And secondly, by giving you an enema, you'll understand the process on a personal level. This will help you learn much faster."
"But I'm feeling fine," Sakura said, in an attempt to get out of it.
"There are no side effects, and even healthy people take them from time to time for personal hygiene." Shizune walked Sakura over to the bed in the corner of the office, and immediately started with taking down her apron skirt. Sakura noticed the box of pink disposable enemas at the end of the bed. There were too many to count. Next, Shizune effortlessly removed her black shorts, and finally, her white panties. "You smell great, Sakura. If every patient was this clean, our job would be a lot more pleasant."
Sakura blushed. What came next though, she did not expect. Shizune pressed her down onto the bed and began unzipping her red top. Sakura grabbed her hands and glared at her with a betrayed look.
"Sakura, in order to complete this lesson, you must understand how every bit of the human body reacts to an enema. In order for you to experience it with all of your senses, you need to completely undress. If you back out here, you fail."
With a sigh, Sakura let go of Shizune and closed her eyes. Shizune worked faster now, and in just a few seconds, Sakura's top and bra were off, revealing a modest but gorgeous set of breasts with pink nipples.
On Shizune's command, Sakura lay down on her back and spread her legs wide open. Shizune grabbed one of the disposable enemas from the box. The bulb of the enema was a translucent pink, and the clear liquid inside of it was visible. Extending from the plastic bulb was a tube that was clearly meant to be inserted into the anus. Shizune removed the cap and brought the enema to Sakura.
"Inside every enema is glycerin, a liquid that induces diarrhea. The tube is already lubricated, and is meant to be fully inserted into the ass. The hole at the end of the tube is where the glycerin comes out when you squeeze it."
Shizune brought the enema to Sakura's private area, and with her free hand, spread one of Saura's butt cheeks to reveal the anus. "Always make sure you can completely see their asshole before you insert the enema."
Sakura nodded, and Shizune continued. She pressed the tip of the enema on the center of Sakura's rose bud and gently pushed it in. When there was a bit of resistance to the insertion, Shizune twisted the tube a bit while applying a bit more pressure. Sakura could feel the tube going inside of her and let out a slight moan in response.
"As you can feel now, the rectum is very sensitive," Shizune explained, as the enema was fully inserted. "That's why you have to be careful. Some patients are turned on by the sensation, so expect boners from male patients and wet vaginas from female ones."
Sakura would never have guessed that she'd be one of the people turned on by an enema. Her vagina dampened, and a massive urge to masturbate overwhelmed her. Shizune squeezed the enema, and the cool liquid flowed into Sakura.
"Just like how you can feel water going down your throat when you drink, your rectum will feel the liquid going in as you receive an enema." Shizune continued to squeeze until most of the liquid had been injected. Then, she slid the enema out and showed it to Sakura again. "See this?" She let go of the fingers pinching the enema bulb and air came rushing back in. Once the bulb had fully expanded again, Sakura could see about a third of the glycerin remaining. "By the design of the disposable enema, you will never inject all of the liquid in one go. When you've squeezed as much as you can, you pull it out, let the air refill, and then you reinsert it to inject the rest."
Sakura nodded, and Shizune went back to her private area and re-inserted the enema. "Once it's in the second time, you lift it up a bit so the remaining glycerin flows down to where the tube is. Otherwise, you'll be injecting air first, and you won't be able to inject every last drop. Alternatively, the patient can reposition themselves so that their butt is facing the air. That way, the enema is pointed down." Sakura opted to continue lying on her back, and Shizune did as she had just instructed. When the tube was fully inside Sakura's asshole again, Shizune tilted the bulb up. The tube inside of Sakura's ass was pushing down in response and Sakura let out another small moan. Quickly enough, Shizune squeezed the rest of the liquid in and pulled the enema back out. She gave the empty enema bottle to Sakura, who brought it closer to her nose. The enema tube smelled like her butt, and there really wasn't any more glycerin left inside. Before she could make any more observations though, her rectum began to burn and her stomach churned.
"Patients will react to the enema between 30 seconds to 2 minutes. The burning sensation is perfectly normal, Sakura, so don't freak out."
Sakura shot up and looked around the room for the washroom. There wasn't one anywhere in sight. "Shizune, I need to go right now!"
"Then go right now," Shizune said, pressing Sakura back down. "The final part of the experience is understanding how your body reacts to it. Your nipples are erect and your vagina is wet. It's evident that you're turned on by it, you dirty girl." Shizune forced an index finger into Sakura's anus. "The insides of your butt is soaking wet too, which is proof that the enema is working. You should also be feeling extremely weak, because enemas drain strength." Shizune was right, because Sakura struggled very weakly and was unable to break free. The urge to evacuate was growing stronger and stronger.
"If your patient resists an enema," Shizune whispered erotically into Sakura's ear, "you should give them another one." Keeping Sakura pinned down, Shizune grabbed another enema from the box, uncapped it, and gently slid it into Sakura's asshole. Sakura kicked and turned but it was no use. Tears began to flow down Sakura's cheeks as Shizune squeezed the liquid inside of her ass once again. Finally, Sakura's vision began to blur, and she knew that the second enema had done it. Her fight was over. She covered her face with both her hands as soggy brown shit flew out of her anus, along with the glycerin that had been injected. The shit was blasted all over the bed in front of her, and onto the floor as well. Sakura had lost all control of her rectum as it spasmed uncontrollably, and before she knew it, she was pissing herself while excreting the remainder of her watery shit.
Shizune pried Sakura's hands out of her face and forced her to stand up to show her what she had done.
"Another thing you should always remember is that if the patient makes a mess, you have to clean it up."
Sakura's tears slowly began to dry as she grabbed the mop from the closet. Shizune took a seat to watch.
"Oh, and don't look so worn out, Sakura. After you finish cleaning, you're going to give me the rest of the enemas. If you're angry that I humiliated you, you'll soon have your chance to get even."
The thought of Shizune writhing in pain and shitting herself gave Sakura a bit more strength as she cleaned her shit. The thought of receiving a dozen enemas from a pissed off student excited Shizune so much that she began to discretely rub herself when Sakura was looking away.
Shizune's up next. If you enjoyed this, please leave a review.
