“You must be crazy! There's no way you're using that thing.”

She was totally terrified...

“Silvia, please... you've never used such a big nozzle!”

She blurted out, jumping up a little!

Silvia, who already had the second syringe in one hand and cotton wool in the other, was beaten to it by her friend.

“Giulia, stop acting like a child!” She said, almost shouting.

“It's your fault we're here now. We'd rather be at the beach. Instead of whining, you should thank your sister for taking care of you!”

Girls like you need a good spanking, just like they used to do in the old days!

Silvia, in complete agreement with Floriana, added fuel to the fire.

“Floriana is right! If you hadn't come home drunk again, we wouldn't be here now!

“Now be a good girl, lie down so I can give you your second injection.”

Giulia, red with shame and not in the best shape, could no longer find the strength to argue back and could only manage a timid “ugh” as she turned onto her stomach, ready to receive the dreaded vitamin injection.

Silvia approached her sister's bottom again and began to gently massage the upper part of her left buttock with cotton wool soaked in alcohol.

The cold on her skin sent a small shiver down Giulia's spine, causing her muscles to tense slightly.

Silvia, knowing this reaction, told her to relax and began to gently touch the area where the injection would be given with her fingertips, then with her usual decisive gesture, she stuck the needle into the young girl's bottom.

Giulia, now at the mercy of the situation, tried to remain still, waiting for the liquid to start entering, but as soon as her sister began to press the plunger to inject the red liquid, the poor girl began to feel a terrible burning sensation.

“OOOUCCHH It burns, it burns!

Please take it out, I can't stand it!

Silvia knew her sister would react that way.

In fact, in addition to the usual 3ml of vitamin mix, which was already a little painful in itself, she had added another 2ml of water for injections to the syringe. She had used the sterile solution on herself once, partly for fun and partly to test its effect, and she still remembered how much her bottom hurt after that injection she had given herself!

It wasn't the first time she had enjoyed making injections a little more painful than normal, and this time, when her sister had behaved really badly, she didn't hesitate to fill the syringe completely by mixing the two liquids, creating a mixture that would be a real punishment for Giulia.

Silvia continued to slowly press the mixture into her sister's bottom, trying to calm her down.

“Giulia, be good darling, we're halfway there.”

But the pain for the poor girl was truly terrible, and she continued to scream and cry like a child for all those endless five milliliters.

Finally, all the liquid went in, and Silvia slowly pulled the needle out of her sister's buttock, immediately applying cotton wool to the injection site so she could massage it well to distribute the liquid evenly.

Giulia, her eyes swollen with tears and her bottom still terribly sore, continued to whimper during the massage, knowing that the worst was yet to come and that those two would give her the enema, ignoring her complaints.

In fact, after enjoying that painful injection, Floriana couldn't wait to see how Silvia would handle the enema.

In fact, as soon as she put the empty syringe and cotton ball on the dresser, she wasted no time in starting to organize the second and no less difficult part of the visit.

“Giulia, now get comfortable on the bed on your stomach.

Put the pillow under your stomach if you need to...

That position would help Silvia insert the nozzle, making the girl's orifice more accessible, but it would certainly be much more embarrassing!

Giulia, still naked on the bed and slightly curled up on her side, did not want Floriana to see her in that position, especially while she was being given an enema, and she attempted a timid protest.

“No, Silvia, please! I'm embarrassed!”

Floriana, who had been standing next to the 18-year-old the whole time enjoying the show they were giving her, tried to reassure her and help her get into the position her sister wanted.

“Giulia, don't worry, I've known you since you were born, we're among women... give me the pillow and I'll help you...” she said in a calm and reassuring voice.

Her sister placed one hand on her shoulder as a gesture of consolation while gently removing the pillow from under Giulia's head with the other, then began to help her get into position.

She gently guided her movements and, after lifting her pelvis slightly, placed the pillow under her stomach, bringing the young girl's bottom into position for the enema.

She couldn't help but notice how embarrassing that position must be for an 18-year-old girl, completely naked and now with her genitals and little hole practically at the mercy of the two girls.

While he understood Giulia's discomfort, he also envied his friend, who would soon be inserting the large nozzle into her little butt, punishing her for her various acts of disrespect.

She sat down on the bed next to the unfortunate girl, knowing that she would soon need comfort.

Silvia, meanwhile, satisfied with her sister's cooperation, had filled the bulb syringe with soapy liquid and, after carefully lubricating the nozzle, approached her sister armed with the enema.

Silvia knew, however, that the bulb syringe required two hands to squeeze properly in order to extract all the liquid, and every time she had used it, she had always found it a bit difficult. Insertion and subsequent emptying were a bit complex using only one hand if she had to use the other to spread the buttocks of the patient on duty.

Today, however, luckily for her, her friend Floriana was there, and she thought she would be happy to help her with this procedure.

“Florian, I need your help.”

Floriana jumped to attention, waiting for nothing else...

“Sure, Silvia, what do I need to do?”

“Since this bulb nozzle is a bit large, could you hold Giulia's bottom slightly open?”

As soon as she heard those words, Floriana's eyes lit up and in an instant she placed her hands on the poor girl's buttocks.

Giulia wanted to bury herself in shame. She wasn't generally modest, but this was really too much, so instead of cooperating, as soon as she felt Floriana's hands on her skin, she clenched her buttocks in resistance and begged her sister not to give her an enema.

Floriana understood Giulia's embarrassment and tried to convince her gently, telling her that they would get it done sooner and it would all be over more quickly.

Silvia, on the other hand, tired of her sister's protests, threatened her!

“Giulia, open your buttocks properly or I'll spank you like Floriana said!”

Hearing her sister's angry words, Giulia relaxed her buttocks, which began to open with Floriana's help.

Grasping the two buttocks firmly with her hands and finding no more resistance, Floriana opened the girl's bottom in an almost obscene manner, completely exposing the young hole that was now ready to receive the nozzle.

Silvia, almost surprised at how quickly Floriana had spread her sister's buttocks, had already approached, holding the large bulb syringe in her hand. With both hands, she finally placed the nozzle against the sphincter and, after telling Giulia to relax, began to press it in.

However, Giulia, partly because of the size of the nozzle and partly because of the tension, began to feel a lot of pain and immediately started to complain.

“Ouch, Silvia... it hurts!”

“Stop, pleeease!”

Silvia initially ignored her sister's complaints and continued to push to get the large plastic tube in, but she had to give up when she noticed how tense and tight her sister was.

“Giulia, try to relax...Now I'll lubricate your bottom a little, so it will hurt less.”

After placing the bulb syringe on the bedside table, she reached over to the dresser and took the tube of lubricating gel she had used to lubricate the nozzle.

She squeezed a generous drop onto her sister's little hole, and as soon as she felt the cold gel, Giulia arched her back.

With her middle finger, she began to gently spread it over the sphincter, making Giulia die of shame.

She lay there motionless while Floriana held her buttocks open and her sister touched her in such an intimate place, as only a few boys had ever done!

The umpteenth protests were not long in coming. Silvia had decided that to facilitate the insertion of the nozzle and dilate it a little, it would be better to lubricate it internally as well.

So she began to insert her middle finger into the poor girl's bottom right under Floriana's watchful eyes, making the whole thing extremely embarrassing.

“Silvia, NO! Please... not like that! …please… It's too embarrassing!!”

Her sister, albeit in a very professional and careful manner, was penetrating her buttocks in a way she had perhaps never done before.

That delicate yet invasive movement of that finger inside her began to generate waves of heat that she couldn't tell whether they were due to extreme embarrassment or perhaps slight arousal.

The one who was definitely aroused was Floriana! The spectacle offered to her by the two sisters was absolutely incredible. She would never have imagined that Silvia would subject Giulia to such delicate treatments right in front of her, nor would she have imagined that seeing a girl of that age undergo them, as if they were a punishment, would excite her so much.

Perhaps it was the heat in the room or perhaps it was the excitement, but she felt herself boiling and wanted so much to touch herself, enjoying the scene that was unfolding before her eyes.

After almost a minute of lubrication, Silvia removed her finger from the poor girl's bottom, ready to return to the charge with the nozzle.

She had already performed several enemas and knew how delicate the insertion of the nozzle was.

With a slow but steady movement, she began to insert the nozzle into her sister's bottom, who, unlike a few moments earlier, no longer resisted, perhaps thanks to the meticulous lubrication, perhaps now resigned to receiving yet another embarrassing treatment.

It wasn't the first enema Giulia had received from her sister. In fact, since her sister had started nursing school, she had received them for one reason or another.

She didn't like them very much, as probably no girl her age did, but especially when Silvia used the hanging bag, she didn't mind the feeling she got when the warm liquid began to fill her belly.

Silvia began to slowly pour in the warm liquid, squeezing the bulb of the syringe with both hands.

The first one was gone, but Giulia knew that unfortunately it would not be the only one, and in fact, once her sister had removed the nozzle from her bottom, she approached the basin again to fill the second dose.

“Giulia, I'm going to give you three enemas, so you'll have about a liter. Try to be good!”

Giulia didn't even have time to answer her sister before she felt Floriana spread her buttocks again to facilitate the insertion of the long nozzle.

She was extremely embarrassed and perhaps afraid of losing some of the liquid from her buttocks, but this time she resisted a little, contracting her little hole slightly.

This time, however, her nurse sister had no qualms and with a decisive movement inserted the long tube into her bottom again, causing her to groan in pain. The second dose of warm liquid began to enter, filling her intestines even more, transforming what had previously been almost pleasure into slight cramps.

To make matters worse, Silvia, once she had emptied the rubber bulb, began to move the nozzle slightly inside her little bottom in order to distribute the liquid better.

Giulia, now completely at the mercy of events, her face hidden in her hands, began to moan, halfway between pain and pleasure.

She wanted to escape, but Floriana not only held her buttocks open but also prevented her from moving. Silvia gave her sister one last moment of peace and removed the nozzle from her buttocks again.

Floriana, very focused on her role, let go again, allowing Giulia's buttocks to close, and watched intently as her friend refilled the bulb. While she hoped this scene would never end, she couldn't wait for Silvia to finish this series of enemas so she could finally be alone and touch herself.

The sound of the water being sucked back brought her back to reality. After refilling the bulb, her friend applied more lubricant to the nozzle, knowing that the third and final insertion would not be easy.

Floriana watched her approach again, armed with the bulb syringe, and with no small amount of joy, she opened the poor 18-year-old's buttocks again, ready to enjoy the third and final torture.

However, Silvia knew from experience that the third insertion would be the most difficult, considering that her sister was starting to feel full and would instinctively not relax her muscles.

So, before penetrating the young butt again, with her finger still covered in the gel used to lubricate the nozzle, she began to touch Giulia's little hole again to make it easier to insert the long nozzle.

The pleasant touch lasted only a few moments, until the poor girl felt that tube entering her butt again.

The only resistance due to her fear of losing fluid was immediately overcome by the lubricant and Silvia's firm hand, who did not hesitate to insert the fifteen centimeters of nozzle and then begin to squeeze the last but no less painful dose of fluid into her.

That third of a liter of warm soapy water, which had been almost pleasant the first time, now squeezed energetically into her by her sister, began to cause her severe cramps and a terrible urge to go to the bathroom.

“Silvia, please let me go, I can't hold it!”

She said, still hiding her head in the pillow.

But her sister was used to the protests of various patients and, knowing that the enema had to be held in for a few moments to take effect, she reminded Giulia of this in a professional manner, but this time keeping the nozzle inserted in her bottom to avoid unpleasant leaks.

In fact, to make sure that the liquid remained inside and was distributed well in the intestine, Silvia, somewhat sadistically, not only left the nozzle inside but also began to move it slowly in and out and in a circular motion, generating a sensation in Giulia that she had never experienced before!
