Knock knock...

It was the second time this week that he hadn't shown up for lunch.

Even her grandparents, who had come down to Salento for a week to visit family who were on vacation there, were upset.

Almost every evening, or rather night, she came home very late, often completely drunk.

Giulia was an 18-year-old who was very resistant to rules and discipline, so much so that in June this year she had failed her senior year, but somehow she always managed to get away with it, especially in front of her parents, who were now tired and helpless in the face of this behavior and had lost the energy to keep up with their disobedient daughter.

Her sister Silvia, six years older, had never been a star pupil at school, but somehow she had always managed to get by, until a couple of years ago when she found something she really liked. After a year of political science down the drain, she enrolled in nursing, a rather demanding degree course but one that made her feel important.

Silvia, like her parents, was also quite irritated by her sister Giulia's behavior, and after yet another embarrassing incident involving her sister and their grandparents, she decided it was time to do something about it.

After lunch on the beautiful sea-view terrace of their vacation home, she decided, in agreement with Floriana, her longtime friend, who was also vacationing at their house, that she would give her sister a good scolding. Floriana couldn't help but agree with her, knowing full well how undisciplined girls of that age could be. The two girls walked over to the 18-year-old's room, which was right next to Floriana's, and knocked on the door.

Giulia, her voice sounding as if it came from beyond the grave, asked who it was.

“Giulia, it's Silvia, can I come in?”

What did she want, why did she want to disturb her?

“Yes, come in, come in...”

She poked her head out from under the covers and saw Silvia and Floriana entering her room. Her sister immediately pressed her.

“Why didn't you come down for lunch? Grandma and Grandpa were upset...”

- I'm sorry, but I was late and I felt sick... I threw up...

Silvia, who was already annoyed, got even angrier when she heard this e d story for the umpteenth time.

“You'd better start behaving more civilly and like a mature person!

“Silvia, don't bother me... I'm on vacation!”

Giulia tried to cut the conversation short, covering her head with the sheet again.

Silvia, on the other hand, had no intention of cutting it short. In fact, the more Giulia acted like this, the more her anger grew!

- Even though you don't deserve it, I'm going to get you something to make you feel better! Floriana, wait here.

“Silvia, it's really not necessary...”

She didn't even have time to finish her sentence before Silvia had already left the room.

She imagined what was in store for her, as had already happened in similar situations. Her sister would give her something to make her feel better, but it was always injections or enemas! She had always been close to her, so it wasn't a question of embarrassment, but she really didn't like certain practices, such as those painful vitamin injections!

It had all started when she began attending that degree course.

For every little problem, Silvia always offered to help her sister or friends, but always with rather embarrassing or painful practices.

It almost seemed as if she had started to enjoy it.

A somewhat sadistic taste that she noticed mainly when she gave her those injections.

Floriana, who had remained silent in the room with her until then, told her that she would do better to follow her sister's instructions and not protest unnecessarily. She had rarely seen Silvia so angry, but she still didn't know what her intentions were with her sister.

Giulia simply nodded her head, hidden by the cotton blanket, thinking that perhaps something to cheer her up a little wouldn't hurt.

The confirmation came along with Floriana's astonishment.

Silvia returned to the room with a basket containing some syringes and medicines.

Floriana couldn't believe her eyes. Was she going to give her injections? Right in front of her, or would she ask her to leave?

It wasn't the first time she had seen an injection being given, and she had even received one from her friend, but she had never witnessed two injections being given to the bottom of a girl about the same age as her students.

Floriana was just starting her teaching career and during some substitute teaching assignments she had encountered girls Giulia's age who lacked any sense of discipline and often deserved severe punishment to bring them into line. In fact, Floriana had often fantasized about punishing some of those girls herself or some older, more professor.

Silvia broke the silence and brought them both back to reality.

“Giulia, since you've been vomiting, I'm going to give you an injection for your stomach ache and a multivitamin injection. It will help you perk up a bit.”

Floriana couldn't believe her ears. Was she going to see that 18-year-old girl receive two injections right in front of her?

It wasn't so much the injection itself that excited her, but rather the idea that Giulia would receive them right in front of someone else.

Giulia had only ever had an injection in front of a friend once before, and it had made her a little uncomfortable, but she knew they were among women and decided not to protest further.

She was more concerned about the pain.

While Giulia remained hidden under the covers, wearing only a camisole and a pair of panties, Silvia placed everything on the bedroom cabinet and began preparing the two syringes.

Floriana, on the other hand, didn't miss a single movement her friend made, being particularly attracted to her professionalism. Looking at those two syringes, she thought it was a very unusual punishment, but it didn't seem particularly severe to her. She had never thought of medical procedures as punishment; she had always imagined the classic old-fashioned spanking.

Suddenly, out of nowhere, she remembered seeing an enema in the bathroom, one of those old-fashioned ones.

She had seen it one morning in the cabinet under the sink while looking for something else and was immediately intrigued. Who used it on vacation? Silvia? That object really intrigued her.

It was white with a long, slightly curved tube, probably originally used for vaginal douches. That would be a real punishment for Giulia. She had received an enema several years earlier and still remembered how embarrassing it had been, but at the same time, she remembered feeling much better afterwards!

She tried not to miss this golden opportunity and, while watching her friend remove the air from the first syringe, tapping it lightly as per procedure, she suggested her idea.

“Silvia, do you know what might help Giulia recover?”

“What?”

Silvia asked, intrigued and always open to advice.

“A nice enema! It would help her get rid of all the junk she drank.”

“Sorry, but I saw it in the bathroom the other day and thought about it!”

She said shyly, almost apologizing for sticking her nose where it didn't belong.

As soon as she heard that word, Giulia jerked her head out from under the covers and waited a second to protest, even though her head still hurt!

“No way, you're crazy!

You're not giving me an enema!

Floriana, having already seen her friend's condescending look, tried to convince Giulia.

- Look, Giulia, it would really do you good. I had to do it too, and I felt much better afterwards!

Giulia was familiar with the practice. Silvia had done it a couple of times when she couldn't go to the bathroom, but she had never done it in front of strangers, and it would be too embarrassing!

Silvia, on the other hand, thought her friend's idea was really good and immediately told her to go and get everything she needed from the bathroom cabinet.

“I agree! Please go to the bathroom and get it. It's in a basin with some soap in it. Fill it with hot water and dissolve some soap in it.”

Giulia couldn't believe her ears. Did they seriously want to give her an enema to punish her?

“Silvia, please forgive me!”

“… please, I'm so ashamed!”

She tried to convince her in every way she could in a last desperate attempt.

Silvia, however, having finished preparing the second syringe, refused to listen to reason.

“Listen, Giulia, today is really not the time to protest!”

“We're doing this to make you feel better! Just take off your underwear so we can give you the first injection.”

Just before leaving the room to fetch everything she needed for the enema, Floriana took one last look at the two syringes ready on the dresser, noticing how unusually full one of them was, at 5 ml.

The idea that her friend's sister was being punished for all her various acts of disrespect convinced her more and more. Every now and then, these girls needed to be taught how to behave.

But the idea that she would be a spectator to this particular punishment began to excite her a little!

Luckily, the bathroom was right next to Giulia's room, and knowing where to find everything she needed, she tried to do it as quickly as possible so as not to waste a single second.

In fact, under the sink, there was a large white bulb syringe in a plastic basin, along with a bar of neutral soap and a tube of lubricant.

It seemed that someone used it often, given how meticulously organized it was!

She couldn't help but notice the size of the nozzle again. It must have been at least 15 centimeters long and thicker than her finger.

It was much larger than the one she had used that time, and she immediately imagined how much Giulia would protest!

She immediately turned on the hot water and, leaving the bar of soap in the basin, filled it as much as possible, roughly a liter of water.

She tested the temperature of the water with her hand and, once she was sure it was warm enough but not too hot, she began to dissolve the soap with her hands until the water became whitish and opaque.

She still remembered that when they gave her an enema, she was told that the water temperature should be about body temperature, and the water in the basin looked just as opaque as the water in the bag she had been given. She removed the soap and placed it on the sink. It seemed perfect to her!

After placing the enema nozzle upside down in the basin full of water and taking the tube of lubricant in her hand, she quickly returned to the small room that would soon be transformed into a clinic.

She hadn't yet returned to her room to fetch everything she needed for the enema when she immediately recognized the smell of alcohol used for disinfecting. That intense smell she had always associated with injections.

The scene she found when she returned to the room was absolutely unforgettable.

Giulia was lying on the bed with her beautiful bottom exposed and her sister busy giving her the first injection, a medication that would help relieve her stomach ache and nausea.

If Floriana was somehow attracted to injections, this image was close to perfection. Giulia was a rather tall girl with two beautiful legs that ended in a nice round bottom. Her 18-year-old skin made that backside perfect for injections.

Silvia had just inserted the needle after gently disinfecting her sister's right buttock. She now had a lot of experience and a very delicate hand.

She firmly grasped the syringe plunger and began to inject the few milliliters of medicine. Giulia, perhaps more for show than anything else, let out a few small moans of pain, perhaps hoping that her sister would spare her the second syringe.

Silvia, accustomed to her complaints, paid no attention and completed the injection, administering all 2 ml to Giulia.

Floriana, on the other hand, had noticed those little moans of pain and, thinking about how much Giulia would complain with the large nozzle she was about to receive, began to feel a slight sense of excitement.

Giulia, lying naked on the bed waiting for the second injection, immediately looked at what Floriana had brought and couldn't help but notice the large syringe standing upright on the dresser. It was much bigger than anything that had ever entered her buttocks, and her blood ran cold at the thought that it would soon be used on her.
