In Jura Tempest Federation: Rimuru City, two young women walked side to side.

One with white skin, light purple hair combed with a ponytail and large purple eyes. Her curvaceous figure is something that cannot go unnoticed with each step she takes. She wears a yellow-green shirt covered up with a purple jacket and purple pants with black and gray belts and black boots. The other is shorter and her skin is similar, but she is different as she has long, wavy, pink hair, coupled with large hot-pink eyes under very light, barely existing eyebrows. She is wearing a simple pink kimono, covered by a similarly simple white robe that covers her arms in excess.

With each step they take, they look at each other. Both are guards of Master Rimuru, founder of the country where they live, so serving and protecting him is considered an honor among the inhabitants of that country.

Despite being friends, both girls have maintained a rivalry for years and are always trying to show who is the best in order to achieve a much higher degree in the hierarchy, but this can be achieved only by completing the most difficult tasks.

Shuna, the girl in the pink kimono, had the category of princess, which gave her much more prestige to increase her social status, plus the fact that she is much better at the tasks assigned to her, which in the end aroused the frustration of Shion, the girl sheathed from head to toe in the tight purple outfit.

"You know I'm better than you," Shuna said, waiting for her partner to finally accept who was better of the two.

"Of course not," Shion replied. "If we did a competition, I would beat you with ease."

"Are you challenging me?"

"Of course! I know you wouldn't hold out against me. Suggest any challenge and I will take care of making you bite the dust, little princess."

Shuna clenched her fists at the notice of her friend's challenging attitude, but to protect her honor, she was willing to accept, but she would not let a simple challenge stain her reputation, so she decided to respond quickly and thus accept the request her friend had made, but on her own conditions.

"So you want a challenge eh? Well, how about it if we get in the ring and see who can get the other one out..."

"It sounds pretty good," Shion said, feeling confident that she could beat her rival in a fighting ring.

"We just won't use our punches to fight, but we will do it with our butts."

"What?!"

"You said I could suggest any challenge right? So, I want us to fight in the ring, but using all the strength of our asses to make one of the two fall and bite the dust, just like you say you can do it."

Shion didn't have much ability to carry out a fight with her own ass, but she knew that if she refused the challenge then she would be left as a coward. If Shuna made this news public, then this would not allow her to move towards the position she so wanted: To be the master guardian of all. With his goal clear, Shion knew what she had to do.

"Very good, let's go then."

To prove their bravery, they both went to a huge fighting ring where they would face off to prove who was the best of them. For the challenge, both left their typical outfits and changed their clothes to wear a set composed of a sports top and shorts that showed their extraordinary bodies, which were sweating thanks to the heat of the day.

"It will only be you and me," Shion said.

"I wasn't expecting anyone else... Surely you want to prevent everyone from seeing your defeat, but don't worry, I understand it and I will be kind to you so that you don't go home humiliated."

"Let's make a deal then if you're so confident..." Shion proposed.

Curiosity grew in Shuna. Earning more than respect and prestige could be an interesting thing that would add some flavor to the battle.

"What do you propose?"

"Whoever wins will become the other's Mistress."

"What?! What do you mean by Mistress?"

"It's simple," Shion explained as she warmed up to be ready for the challenge against her friend. "If I win, you will recognize me as your Mistress and do everything I tell you as a good apprentice, whatever it is and without refusing."

Shuna analyzed the idea because she found it impressive. Her own friend was offering to be her apprentice in case she lost, something that would surely happen, as she had always shown that she was much better. Many ideas popped into her head and Shuna felt excited while thinking about everything she would put her friend to do when she lost. There were endless possibilities ranging from her Shion doing her laundry, carrying her things and even admitting in public that she was a loser.

"All right, I think that's a perfect for the winner," Shuna said.

"Then let's not wait any longer and get up!" shouted Shion.

Already in the ring, both girls stared at each other. There was no one to speak to give them the indication that they should start, but they were so focused that they didn't need that. The one who made the first move was Shion, who ran with impressive speed to catch up with Shuna, who didn't expect her friend to attack her so fast.

Fortunately, Shuna managed to dodge Shion just before she tried to hit her with her bulging butt, which passed right next to her and hit the ground along with the girl's entire body.

"Good try," Shuna cried. "Is that all you have?"

"Of course not!" Shion shouted to run back to her friend and try to attack her again.

Shion relentlessly attacked Shuna, who with each blow she dodged noticed something that made her loose concentration. Her friend Shion was now showing a lot of skin and looked quite sexy dressed that way, plus her wild attitude and passion were something that made her feel the thrill of battle.

Even though Shion wanted to hit her, Shuna felt quite attracted to her friend, something she wouldn't have imagined but was now happening.

Thoughts slowly clouded Shuna's mind, and she imagined herself naked before Shion. In that fantasy, they were both kissing and their bodies were glued together as they touched each other everywhere.

"I got you!" shouted Shion when she saw that her friend had neglected her defense and left a huge hole on it.

Shion's butt hit Shuna in the face so hard that it made her fall immediately. The pink-haired girl flew out of the ring and stared at the sky. Looking at the bottom of her shorts, she could notice a huge spot that had been created where her pussy was. The excitement of that fantasy had made her get wet and that had made her lose, but apart from losing, the important thing was what she had felt.

Shion didn't stop celebrating and jumped as high as she could. She had gotten her friend to accept her as her Mistress and this would be something she would take advantage of. The ideas she had to carry out with Shura were very different and soon her friend would find out.

"Let's go to the hot springs," Shion said as she offered her hand for Shura to stand up.

After having had such a hectic battle, the girls walked to the hot springs so they could relax. Shion hadn't forgotten her agreement and only thought about the way she would subdue her friend; Shura for her part was deeply curious about what would happen after she had lost that battle. Everything would be resolved as soon as they were alone in the hot springs.

The clothes of both girls fell and they entered the hot water to enjoy for some time, and as soon as they were completely submerged, Shion took her role as Shura's new Mistress.

"Well my dear, now that you lost, you will have to do what I tell you."

The warmth in Shura increased as he heard what Shion told her. In a normal situation, she would have objected to what she was told, but seeing Shion's naked body through the water increased her excitement much more. She had never seen her naked and having that voluptuous body in front of her awoke her darkest instincts.

"Okay Shion, I will do what you ask."

"Excellent! I'm glad you respect our deal, but from now on you will call me Mistress Shion, understood?"

Accepting what she would now have to do, Shura replied with complete sincerity.

"Yes, Mistress Shion."

Shion's smile increased and knowing that she had control over her new acquisition, she would use all the time she had alone with her to enjoy the fruits of her victory.

"Now I want you to come and massage my body."

"Yes, Mistress Shion,"Shura said mechanically and placing herself behind Shion so she could massage her.

The girl's hands passed through Shion's soft back and as she made contact with the skin her excitement grew even more. Now Shura no longer knew who was enjoying more.

With gentle movements, Shura traveled through Shion's back with her hands and Shiob turned to be naked before her friend, who smiled with hunger.

"I want you to massage my tits, Shura," Shion ordered.

"Yes, Mistress Shion," Shura said with a smile and feeling glad to be able to obey the girl who would now be her Mistress from now on.

Now nothing mattered. Shura had lost a battle and the humiliation had been too great, but on the other hand, she had won a prize that nothing could give her, and that would be that fantastic body her friend had. Shion believed that this would be a bad thing for Shura but in the end it was the opposite and the pink-haired girl was truly enjoying.

Without Shion asking, Shura did a little more and began to give soft circles to the girl's nipples, making them go hard from the treatment they were receiving. Afterwards, Shura took both breasts and squeezed them tightly, making her Mistress scream loudly.

"Oh Shura!"

"Do you like this, Mistress?"

"Too much, don't stop," Shion asked.

"Whatever you say, Mistress Shion."

Driven by the joy of her Mistress, Shura guided her mouth to take one of Shion's hard nipples and stuff it into her mouth to suck it gently. While this was happening, Shion spoke to her girl as if she were a baby.

"That's it, my cute Shura, keep sucking until you get some milk."

Although the two knew that there was no way for Shion to lactate, Shura kept sucking with joy, waiting in her mind for even a single drop to come out and feed her, while Shion looked with a smile. She then ran her hand over Shura's head and stroked her with a maternal instinct.

"You don't know everything I've imagined I'll put you to do Shura... Now that you're at my disposal, you're going to have quite a few changes from today."

Shura walked away from the delicacy she was eating and looked at her Mistress with tender eyes.

"What do you have planned for me, Mistress?"

"I think we can change your look a little bit, and the way you dress too, and make you a much sexier and more confident person. I love confident women."

"Whatever you say, Mistress."

"And not only that. You will also sleep with me at night and have sex until we can scream no more… When we wake up, you're going to take my breakfast to bed and help me get dressed, just like a good guard would."

"Yes, Mistress."

"Why don't you suck my pussy?" asked Shion as she felt soaked and ready to cum.

"Of course, Mistress," Shura said.

The girl's head slowly and inevitably lowered to meet the pussy while the young Mistress sat on a rock and opened her legs to welcome the one who would devote herself to giving her pleasure for a long time.

Having a little doubt, Shura stood motionless, but this was soon corrected when Shion took Shura's head and guided her inward.

Shura let herself go and closed her eyes so that she could devote herself completely to sucking that female organ with joy. The simple smell made her feel hungry and her tongue went through her labia, finding the entrance to that damp cavern easily and making the young woman who was receiving these touches groan with pleasure.

"Ohhh Shura! We will do this so many times! You don't know what I have planned for us! Before everyone, we will be friends and even rivals, but when we are alone, you will be at my feet to do this again and again until you can no longer, and even if you can't, you will continue to do it!" said Shion with joy, stroking Shura's, who was now too busy to speak. "Who knows what else you will be able to do to me? The sky is the limit! We can try all kinds of things!"

Without even paying attention to what Shion was saying, Shura found herself licking quickly, thus getting Shion to turn red. It only took a few licks for Shion's pussy to shoot several jets that ended up both in the water and in the face of Shura, who only laughed when she felt what was coming towards her.

"Damn, Shura... This was so good!"

"What else do you want me to do, Mistress?"

"Well, I think you've already given me enough pleasure, but I wish we had something different now."

"Whatever you want Mistress."

Shion got up from the place where they were and went to a rock, where she found a huge dildo surely another girl had used. Without saying anything, the girl took it to the water to rinse it off and make sure it was wet enough. Then, she gave it to Shura, who was left with a hesitant expression.

"Open those legs well Shura, because I'm to fuck you with this."

Shura didn't even seem to care and she got up to leave her pussy exposed to Shion's astonished gaze. "Do what you want, Mistress." Although she had never experienced a similar situation with a woman, she now said it completely seriously and really wanted Shion to stick that huge dildo in her pussy.

With a lot of confidence, Shion stood up and without saying anything else put the dildo in Shura's pussy. "Look how easy this thing gets into you Shura! You are so wet that it's not even hard to penetrate you!" Shion's words echoed in her friend's mind and she closed her eyes to let herself be carried away by pleasure while her lips contracted, making a sensual grimace, but seeing this, Shion decided it was better to enjoy the show from a different angle. "Come on honey, take that and put it in by yourself, you don't need my help."

"Yes, Mistress Shion."

Fortunately for both girls, there was still a lot of time left, and the night would be quite long. Who knows how much would happen while they were there, but it would have to be seen.

To be continued.
