Chapter Text

[Awakening completed. Welcome, player] was what was written on a floating blue screen while Agaru, a young otaku, drank his coffee with a sleepy face and huge dark circles under his eyes. He sipped his coffee while staring at the floating screen without much emotion, apparently sleep was still affecting his reasoning and notion.

(Okay, this doesn't happen every day...) he thought, then immediately took a sip of the coffee in the mug in his hand. He continued reading what was on the screen as he sat on the porch of his house, feeling the first rays of sunlight that were beginning to brighten the day.

[You have been blessed with the ability to steal the ability of anyone you can touch.] After reading this, he just took another sip from the mug and raised an eyebrow. (This ability is... completely useless... I don't live in an anime or manga to use it, no one in my world has a special power for me to use it, at least I think. Unless...) He paused for a few seconds before finishing his thought (... may this also apply to other characteristics that are not exactly powers). Aguru concluded while placing his free hand on his chin, still a little thoughtful.

(But where the hell did that screen come from?) he wondered as the reality of the situation began to sink in, but unlike the vast majority of anime fans, he managed to hold on to the idea of having his own system, although his heart pounded faster with the reality that was in front of him.
(Okay, if this happened to me, it certainly happened to more people around the world... and if it happened to more people, I can steal them thanks to this ability... if I was the only one who had this "awakening," then I have the ability to steal powers in a world that has no powers, in other words, practically useless) Aguru thought as he covered his mouth, looking coldly at the screen in front of him.

Aguru leaned back in his chair while sighing with a smile on his face, bringing the mug closer to take another sip of his coffee (anyway, this ability is extremely-) before he could complete the thought, a sort of hole appeared in the air above Agaru's backyard. Agaru stared in amazement before being surprised again by a person falling from that kind of hole. All nerd fans know very well what that floating hole was; it was some kind of portal.

(W-what is this!?) Agaru thought as he got up from his chair and approached the being that had fallen into his backyard through that portal. As he approached, the portal disappeared, leaving only a completely unhooded figure of below-average height. Aguru simply looked down at the mysterious figure, somewhat warily, before crouching down and removing the hood that hid the figure's face.

After removing the hood, he saw a young girl who appeared to be about 16 years old, like him. She had long purple hair with small horns on her head, and a sweet fringe covering her forehead. The girl appeared unconscious, which was to be expected given the impact she had made when she fell to the ground when she passed through the portal.

Aguru looked at the young woman in astonishment as he set his coffee mug aside to shake her awake. "Hey! Are you okay!?" he exclaimed, shaking her shoulder. The girl gave no sign of responding, but she seemed alive thanks to her breathing, which made her torso move slightly.

"Holy shit, what the hell is going on today, huh?" He muttered to himself as he glanced around to see if anyone else had seen her fall into the portal that had suddenly appeared. Aguru held the young woman in his arms and lifted her easily; her body was quite light. (Anyway, I can't leave her lying here on the grass and let anyone see a woman with... horns?) He noticed the girl's horns and raised an eyebrow. Soon after, he began to carry her into the house and lay her down on the living room sofa.

A few hours after the incident, the young girl began to slowly wake up, still a little confused and with slightly blurred vision. When her vision returned to normal, she could see Aguru sitting in a chair in front of the sofa, staring at her. He was apparently waiting for her to wake up. The mysterious young woman quickly sat up but soon realized something was wrong: her legs and arms were tied behind her back with a rope.

"W-who are you?" the purple-haired young woman asked loudly as she began to struggle, trying to free herself from the ropes. Aguru just furrowed his brow and covered his ears when the young woman screamed. "You don't need to scream, I'm in front of you!" he exclaimed, slightly irritated by her screams.

"Shut up and tell me who you are!" the young woman exclaimed, looking at the black-haired young man sitting in the chair in front of her. Aguru looked at her askance, seeing that she was giving orders even though she was in a clearly unfavorable position. “Look, you’re the one who invaded my backyard, so you’re the one who owes me an explanation, young lady.” He said as he crossed his arms and looked at the girl.

 

"I trespassed? It's not my fault your land is in my teleportation area, huh!" She turned her face to the side with an irritated expression. The young man just rubbed his eyes after hearing her answer and replied, "Can you at least tell me your name, girl?"

"I'M NOT A GIRL, I'M A MAN!" the young woman exclaimed, clearly irritated, or rather...irritated, her face flushed and embarrassed. Aguru was surprised by this statement, after all, this person's expression was extremely effeminate. "You're a man? But your face is so effeminate—" And before he could even finish, he was interrupted by the pink-haired man. "YES, YES, I KNOW! YOU DON'T NEED TO TALK ALL THE TIME ABOUT MY APPEARANCE!" He scolded the black-haired young man as he tried to free himself from the ropes.

As he tried to free himself, he stopped for a second and looked at Aguru, giving a sarcastic smile. "I won't be tied to these ropes here." He seemed to start concentrating quietly for a few seconds
...
"
Hmm? Why isn't it working? What happened to my ability?" The pink-haired boy began to question himself and try to free himself again. "You mean this one?" Aguru raised his hand and created a portal next to him. The purple-haired boy's eyes widened in disbelief at what he was seeing.

"W-what did you do to my ability?!" The pink-haired boy questioned in a loud tone again. "First of all, you're very excited, let's introduce ourselves more calmly. My name is Aguru," Agaru said as he crossed his legs, waiting for the pink-haired boy to calm down.

The pink-haired boy sighed and looked at Agaru menacingly. "I'm Izi, now answer my question," he replied to Aguru rudely.
"You don't seem very sociable," Agaru said sarcastically, but then immediately responded to Izi's doubts. "I stole it, now your ability belongs to me." After he said this, Izi was startled and slightly euphoric. "WHAT!?" Izi screamed, unable to believe what he was hearing.

"You're not deaf, I stole your ability. It's actually quite interesting," he replied with a sarcastic smile on his face. "You bastard! Give it back to me now!" Izi exclaimed as he began to try to free himself from the ropes again. "I'll give it back if you calm down and talk like a person!" Agaru replied, crossing his arms again.

Izi sighed, clearly irritated by the whole situation. "Okay, what do you want to talk about, human?" he replied irritably, giving up trying to free himself from the ropes that bound his arms.

"Now that's better. Well, first of all, you don't look human because of those horns of yours, not to mention that your ability allows you to make portals to another dimension. I ask you, what are you?" Agaru asked, analyzing the whole situation. Now that he had Izi's ability, he could make portals to other dimensions.

"Do you already know how my ability works, you bastard?" Izi spoke, still irritated, before answering Agaru's question. "I'm an Incubus. I came from another dimension. I had a slight complication during my journey and ended up losing control of my ability and ended up here, that's all." Izi replied more calmly.

"An Incubus? Interesting... why do you have such an effeminate appearance?" Agaru questioned. "I WAS BORN THIS WAY, YOU BASTARD!" Izi responded, getting irritated again.

"Okay, okay, no need to shout." Agaru spoke, rubbing his ear.

"Is that all?" Izi questioned him again, still maintaining the rest of the irritated.

"Well, yes, I guess." Agaru replied while playing with his hair, thinking for a moment.

"Okay, give me my ability back now?" Izi said, looking at Agaru.

"Well... I kind of don't know how to do that." Aguru replied while rubbing his hand behind his head, embarrassed for lying to the pink-haired boy.

"You what?!" Izi gritted his teeth as he glared at Agaru, wanting to cut the human into pieces. "What do I do now? You bastard!" Izi cursed him as he tried to escape the ropes again.

Agaru, on the other hand, completely ignored what Izi was saying while thinking (he's an incubus, could it be that my ability allows me to steal his incubus characteristics? Would he stop being an incubus if that were really true? Well, there's only one way to find out...) Agaru started walking towards Izi, who in turn looked strangely at Agaru because of his sudden approach, soon after he placed his hand on the pink-haired young man's head

"What are you doing?" Izi questioned him but received no answer from Agaru, soon Izi felt his body suddenly become weaker, his small horns didn't disappear... but something else had been stolen from him. He became a little tired and looked up, and when he looked, he noticed that small incubus horns had appeared on Agaru.

"W-what did you do?" Izi questioned as his breathing became heavier due to the sudden fatigue that he suddenly felt.

(cool...) Agaru thought as he touched the small horns above his head. Soon after, the blue screen appeared again with the following information:

[incubus characteristics]
[1 - Libidinous strength: your general strength increases as you practice sexual activity]
[2 - Increased libido: you can increase your libido as much as you want]
[3 - Controlled pregnancy: you can choose whether your sperm will be able to occupy an egg or not]

(Cool, very cool...) He continued thinking as he looked at the features he had just stolen from Izi and stroked the little horns that had just appeared on his head.

"Did you become an incubus?" Izi wondered, looking at Agaru. Soon after, the screen disappeared and Agaru looked down at Izi, his gaze fixed on the small, pink-haired youth who was tied to the sofa. "Yeah... you're feminine enough." Grabbing Izi's shoulder and pushing him against the sofa,

Izi was startled and tried to free himself from Agaru, but the difference in size and strength between them was noticeable. While Izi was 5'1", Agaru was 6'1". "What are you doing, Human!?" Izi asked as he tried to escape in vain from Agaru who was on top of him on the couch.

"I stole some of your incubus characteristics. Apparently, you guys get stronger while performing sexual acts, so I'm going to test that now." Agaru spoke without any shame as he lowered Izi's pants, revealing a small 6cm penis. "Look, for an incubus, you have a very small dick. Izi, I think that must explain your effeminate appearance." Agaru spoke in a mocking tone to the small, helpless incubus beneath him.

"S-shut up." Izi just blushed and turned his face away, embarrassed at being treated like this by a human. "You can't be serious! Let me go already! Stop it, you little shit!" Izi exclaimed as he began to get nervous when he saw Agaru starting to lower his pants and reveal his 25cm member. Izi swallowed hard, his heart pounding as he saw that cock, much larger than his own.

Agaru held the little incubus under the crook of his knee, lifting his legs up while pressing the head of his penis against Izi's entrance. Izi began to sound cold and desperate. "WAIT! HUMAN! YOU'RE A MAN—grrrrr!" Without letting the little incubus finish, Agaru thrust himself into the little demon's tight entrance.

Izi's entire body shivered as he felt that organ enter her tight little ass. "D-bastard, I'm going to kill you—" And again, not letting him finish, Agaru began to move his waist and push his member against Izi's entrance.

Agaru's cock was squeezed by the demon's incubus ass, which was bound by the ropes. Epe just tightened his grip on Izi's knees and continued his back-and-forth movements inside the little demon. "You actually have a delicious ass for an incubus, are you sure you're not a succubus?" Aguru said, teasing Izi, who was letting out several moans.

"S-shut up, you bastard!" Izi tried to maintain his posture, but his naughty moans only made it clear that he wasn't hating the situation as much as he wanted to show (damn, how does this human have a bigger dick than mine? How did I let it get to this point?) Izi thought as Agaru thrust inside him

. To Ambus's surprise, Izi's small penis was starting to erect as Agaru fucked him. "Look, apparently one of us is really enjoying this" Agaru teased him with a smile on his face

Izi just looked to the side with slightly teary eyes "please, stop..." he spoke in a crying tone, even though the stimulation in his anus brought excitement, it still hurt when Agaru moved like that.

Agaru looked down at him and then immediately released Izi's leg. "Okay, if this is hurting you..." Izi became slightly happier when he released him and began to speak. "...I really don't care." Agaru finished, giving Izi a cold shower.

The black-haired young man held the pink-haired young man's waist and left him lying on his stomach with his penis still inside his anus. "Did you think I would stop? I always wanted a naughty little femboy like you to teach me some manners." He lay on top of Izi's body and began to move his hips again. "You're going to be my little toy from today on." He spoke, holding the little demon's neck, who was moaning and clenching his fists.

As time passed, the excitement increased for both, with Izi getting erect as he was violated and Aguru increasing the pace of penetration. Izi couldn't resist the stimulation any longer and ended up reaching his climax, cumming on the couch while being fucked by the dark-haired young man.

"Looks like you're enjoying this more than me," Aguru teased as he continued to move his hips against the little demon's body. As he sped up, Izi could feel Aguru's penis getting thicker inside him.

"S-shut up," he said with a lustful voice as his mind wandered with each thrust. But soon it went completely white with one last thrust, and along with it, he could feel his insides being filled with a hot liquid.

After Aguru came inside Izi, he stood up, leaving Izi lying on the couch while his liquid dripped from his ass. "That wasn't so bad," Aguru said as he looked down at Izi.

Still with his arms pinned behind his back and panting, the pink-haired young man was still confused by everything that had suddenly happened, but soon after he responded to his abuser, "W-why did you do that? Damn human!" "

I already told you..." as he spoke, a small layer of aura of elevation surrounded his body, "...I'm just testing this ability." The system appeared again, notifying him that his overall attributes had increased thanks to Izi's stolen characteristics.

"Interesting..." He thought aloud and then immediately looked at Izi. "Your Ex-ability is something fascinating, it will be very useful with what I plan to do..."

"And what do you intend?" Izi responded a little hesitant and still a little breathless.

Aguro responded as he approached the back of Izi's neck and spoke close to his ear, "I will fulfill the dream of any lover of current pop culture... make a harem with all kinds of fictional characters, and you will help me with it."

"I will not help you with na- grrrrrr" Izi's response was interrupted when he felt Agaru's penis entering him again.

"You will have no choice, you will be my helping while traveling with your power," he said as he abused the pink-haired body again.

Agaru used Izi's body for several hours without stopping, even when Izi was unconscious he continued to fuck and cum inside the pink-haired boy. As he enjoyed himself, Aguru grew stronger and mastered the new abilities he had stolen from Izi.

Now with Izi in his arms, a bright portal opened in the center of the room, opening an opening to another dimension. Apparently, a wicked being will begin to wander among them and satisfy his own desires with whomever he wishes.

Chapter 2: Let the adventure begin!

Chapter Text

After entering the portal, the place was different, a practically empty place with stars and planets drifting in what appeared to be outer space. However, there was something that seemed to fill this space: a kind of floating island with a house on it. They were in a kind of pocket dimension that had been generated by Aguro's own ability, which in turn had belonged to Izi before being stolen from him.

Entering the house, it was like the protagonist's old house, identical except they weren't adrift on a floating island in the middle of space.
The sound of a cup and spoon hitting the edges of a cup could be heard in the place. It was Aguru, who was sweetening a coffee while sitting at the dining table on one side while Izi remained on the other end.

"Mmm... this is very good... are you sure you don't want some?" Aguru asked Izi, who was staring at him in a serious and irritated tone after the recent events.

"You abuse me, steal my ability, and on top of that, ask if I want coffee? What kind of crazy are you!?" Izi exclaimed as he slammed the table and rose from his chair.

"Hey, hey, hey... it's not like I'm that big of a monster either, hahaha." He laughed ironically as he took another sip of coffee. "I thought you incubus liked that kind of thing. After all, it's something natural for you, isn't it?" The protagonist continued speaking in a calm tone, keeping the cup of coffee close to his mouth and then taking another small sip.

"INCUBUS DON'T WORK THAT WAY!" Izi retorted, shouting, and flapping his arms in irritation. Aguru simply covered one ear as Izi yelled, "Okay, okay, now stop yelling. I'm not ten meters away from you!"

Izi sat back down in his chair, arms crossed, clearly irritated. "Anyway... why did you bring me here?" Izi asked, keeping his arms crossed and an irritated expression on his face.

"Wasn't I clear?" Aguru said as he finished taking another sip of his coffee. "I need a helper to help me when I can't do something, simple as that." He placed the cup on the table and kept one arm on the table as he stared at the purple-haired young man across the table. "Besides... you're a great form of entertainment," Aguru said with a simple smile on his face.

Izi blushed slightly upon hearing those words and turned his face to the side, "So you want me to be your slave or something? Is that what I understood?" Izi asked the protagonist, a little uncomfortable.

Aguru stood up and started walking towards Izi while saying, "I think slave is a very strong word, I would say... assistant." As soon as he was next to Izi, he stroked his head, ruffling his hair slightly.

Izi took Aguru's hand from his head and looked at him with an ugly face. "Cut the bullshit. From the moment you keep me here against my will, it's already slavery." He kept a firm gaze, looking deep into Aguru's eyes. Aguru held his hand in the air after having his hand pulled away.

Aguru let out a smile and then suddenly placed his hand next to Izi's face. "That look... it's so adorable, Izi." As soon as he finished speaking, the pink-haired boy was surprised and blushed again. "Since you want to be called a slave so much, I will respect your will," Aguru said as he slid his thumb lightly over Izi's lower lip, who was completely disconcerted by the sudden situation.

"N-THAT'S NOT WHAT I MEANT! YOU PERVERSE HUMAN!" Izi exclaimed, removing the protagonist's hand from his face. Aguru just gave a small smile while seemingly holding back a laugh at the way Izi was behaving. "Your way is also quite comical to me," he said, keeping one of his hands in front of his boot.

"But anyway, I'll tell you what I really want for you, Izi." Aguru said, sitting down on the dining table and looking at the pink-haired boy. "I want to conquer all the universes, leave them in the palm of my hand, and be able to do whatever I want with them." Aguru raised his palm and then clenched his fists as he spoke. "Maybe you think this goal is completely impossible, but I..." Aguru was surprised to see that Izi was paying close attention and with a look of surprise and interest.

"Hmm? Why that look?" Aguru questioned Izi, who seemed amazed by something. "You...you are indeed the one I've been looking for for a while..." Izi answered him with some success in his voice. "What do you mean? Explain yourself?" Aguru questioned him again, this time crossing his arms as he looked at Izi.

Izi kept his gaze lowered as he seemed to reflect after fitting together some loose pieces. After a while, he gave a slight smile, as if he finally understood. "Of course, the probability of that happening is practically impossible, hahaha." He gave a small laugh and then looked at the protagonist, who was waiting for an answer.

"Let's say destiny led me to you, I guess we can put it that way, hahaha." Izi smiled, showing his teeth slightly as he stared at Aguru. "In the infernal dimension where I came from, there was a prophet demon, Nostradamus. He had predicted that I would meet someone who would be a great leader. The chances of me randomly falling into a specific place among so many possibilities in the multiverse are practically 10 to the power of infinity. In short... it's impossible," Izi said, leaning on the table. "So the person Nostradamus predicted was you. It can only be... "It's you," he finished, staring at Aguru with a slightly cheerful look.

Aguru absorbed all that information, still keeping his arms crossed, and asked, "A great leader, huh? And what would this leader, who is supposedly me, lead?" he asked, resting one hand on his chin.

Upon hearing Aguru's question, Izi just shrugged. "I don't know, you should answer that for me, don't you think?" Izi replied with another question.

Aguru let out a light sigh upon hearing Izi's answer, and then immediately relaxed his posture with his arms crossed. "Well, I have no interest in creating anything like an army or anything like that, but anyway... it will be interesting to travel between other universes with your power, hahaha." He mocked Izi while leaning next to him on the table.

The pink-haired boy also scowled upon hearing the protagonist's provocative laugh. "You're quite annoying, you know that?" He looked stressed as he lightly punched Aguru on the arm. The punch didn't do any damage, it just made him laugh.
"Anyway, where do you plan to go now?" Izi asked, looking at the protagonist with a curious look. "You said it would be fun to go to other universes with this power, I'm curious."

"Hmm, well, I haven't thought of one yet..." Aguru replied, placing his hand on his chin, thinking for a moment. "I'll decide soon, but until then..." After finishing the sentence, he quickly lowered the front of his pants, revealing his semi-erect member. "How about you caress me with that little mouth of yours while I think, huh?" Aguru spoke as he slid his peluga over the pink-haired boy's lips.

Izi's heart raced as he blushed at the same time at the situation. After all, the one making this request now was his new master.
"You really are a pervert... I'll only do this because you're the master of my prophecy..." Izi knelt on the floor and then held his master's organ with one hand. He stared at the cock that was beginning to harden in his hand. He swallowed a little and then brought his face closer to Aguru's groin.
The boy kissed the side of his master's penis, who was enjoying the way Izi agreed to do it quickly, soon after Izi began to lick the base of the member to the tip

The protagonist could feel Izi's soft, wet, and warm tongue sliding over his member. He was loving this sensation. "I'm sure you're quite experienced at this, huh?" he said teasingly as he placed one of his hands on the head of the pink-haired young man, who was savoring his penis while licking it.

"But anyway..." Aguru spoke before pulling Izi's head against his groin, making him swallow the organ completely. "If you're going to do a job, do it right," he said as he felt Izi's throat on his member.

The pink-haired young man was surprised and tried to pull away, but his master stopped him while he began to move his hips and use his mouth like a vagina.
Izi choked and began to gasp for air, but Aguru didn't care as he fucked his mouth nonstop, caring only about his own pleasure.

With each thrust, the young man felt more and more anxious, but He still held firm to maintain his maximum consciousness, although this was a very difficult task.
Izi's eyes watered as his master increased the pace and pulled his hair while rocking back and forth, but he knew Aguru was close to his climax as he moaned.

"Aaaahhh~ your little mouth is so delicious!" He holds her hair tighter and then gives the last thrust, pulling Izi's head as close to his groin as possible.
He releases all his liquid while the pink-haired one chokes on his love juice.

Izi rolls his eyes as he begins to lose consciousness due to lack of air, but before he passes out, Aguru stops him, letting him pull away to get some air while his mouth has the strong taste of his master's fluids.
"You could have *cough, cough* at least given me a moment to catch my breath," he says, sitting on the floor while coughing because of the sperm in his throat.

Aguru just shrugs and responds with a sarcastic smile, "I kind of couldn't hold myself back."
He crouches down to Izi's height, who is sitting on the floor, and then places one of his hands on his chin.
"I already know which universe we're going to," he said as he stroked Izi's chin.

Izi began to recover and soon asked, "What do you mean by 'we'? You're not going alone?" Izi asked, slightly intrigued.

"Of course not," Aguru replied, standing up again and moving away from the fallen boy
. "If I die during some trip with you inside, I assume you'll be stuck in this dimension forever, right?" Aguru spoke, keeping his hands in his pockets as he walked to the center of the room

 

(he... really thought about that possibility...) Izi thought, blushing slightly and standing up too, accompanied by Aguru.
"Yes... you're right..." Aguru spoke, slightly embarrassed. "But well, where do you intend to start then?" Izi questioned the protagonist with some curiosity.

Aguru smiled upon hearing the question and then replied, "I know many interesting universes to visit, but I would die in most of them simply because these verses are too powerful. So, we're going to a universe that will be easy to steal a very strong power and that will allow me to stand a chance against a large number of universes." He spoke in a calm and confident tone.

"Would that universe be?" Izi questioned him again,

"Undertale." Aguru replied as he snapped his fingers and created a portal.
"Let's go to the Undertale universe." He spoke with a confident smile on his face and soon entered the portal.
Izi simply followed his master to this world that he was so confident he could dominate.

Chapter 3: welcome to the ruins

Notes:

(See the end of the chapter for notes.)

Chapter Text

After passing through the portal, our protagonists stepped into a small garden with yellow flowers; they were clearly at the beginning of the Undertale game. The flowers smelled sweet, and they were also very soft.
Izi looked around the cavernous environment curiously, after all, he still didn't know what attracted his master to this universe.

"A pretty cavernous environment, right? It doesn't seem like much to me, to be honest," Izi said as he began to walk around the environment.

Aguru, for his part, stood in the same spot without moving, seemingly trying to remember something. "We haven't walked yet, I recommend that you don't underestimate this universe. You could end up dying if you argue," he said as he began to walk out of the garden.

Izi was a little bothered by Aguru's statement; he had clearly become a little anxious. Seeing Izi's discomfort, Aguru spoke, crossing his arms. "In this world, humans and monsters were at war, and now we're in the monsters' territory. If everything I remember from this world checks out, humans don't have much of a place here."

Izi stood beside him, hands on hips, with a sarcastic smile. "Hahaha, but I'm not even human." He said, completely convinced.

"You're right, but you look human. I would have been careful anyway." Aguru replied calmly.

"Yeah... you have a point..." Izi pouted, his face sullen. Aguru looked at him with that expression and let out a light laugh. "Hahahaha, don't worry, my little slave..." Aguru patted Izi's head, ruffling his long hair. "...I won't let anything happen to any servant of mine." Izi blushed upon hearing those words and spoke shyly, looking away, "I already told you not to call me a slave..."

"Whatever, hahaha." Aguru took his hand off Izi's head, "Let's move on, I want to know more about this world personally after all." Right after Aguru's speech, Izi nodded and they both began to leave the starting area of the game, the garden of yellow flowers

. However, when they were about to leave the place, a person falls into that flower garden. Aguru knew very well what was happening, but Izi was scared and astonished by the body falling from the top of the cave out of nowhere.

"W-what was that?" Izi spoke, half scared, as he looked at the body falling into the garden. Aguru just replied with a simple smile on his face "the protagonist of this world" After answering Izi, Aguru walked closer to the fallen child



Izi approached with Aguru, they both stood around the child who was unconscious in the garden "so... the protagonist of this world is a child? This world really doesn't seem like much to me..." "This

child's power is a complete threat to me, and she would certainly defeat you if she wanted to" Aguru replied Izi in a calm tone, but with a lot of weight in his statement
"the power to go back in time in a saved moment... the determination..." Aguru spoke while holding the unconscious child's hand "now this power is mine..." he says as he began to steal the power of the fallen child

"The power to go back in time? Eh, that really seems like a power however for a child who appears to be about 10 years old" Izi spoke while Aguru clapped his hands clean. Aguru quickly responded while looking at the falling child, "Because it really is. This power is certainly one of the greatest threats to us, but now that I have it in my hands... I don't see anyone who can stop me, hahaha."

Aguru laughed a little until he stopped for a moment, looking at the child. Something caught his attention, a doubt, the doubt that every Undertale fan has had at some point...
Aguru crouched down again next to the child and laid him on his back. Izi found his attitude strange and immediately asked, "What are you doing—WHAT ARE YOU DOING, YOU PERVERT?!" Aguru had removed Frisk's shorts, the fallen child so he could see what his true gender was, and to his dismay... Frisk had a little dick


. "Y-you don't intend to do this kind of perverted thing with a child, right?" Izi spoke, a little nervous and surprised. Aguru soon responded with an ironic tone "I just wanted to know what his gender was, that's all. Why? Did you happen to think about perverted things?" he says making Frisk sit unconsciously without my lap, turning him without the shorts towards Izi "Because you're a demon I thought you wouldn't care" he said caressing Frisk's small member in his lap

"I don't care... I just think it's weird for you to do that kind of thing with someone so young like that" Izi says swallowing a little saliva, crossing her arms and looking away. Aguru just gave a corner of his mouth as he continued to caress the unconscious child's member "to tell you the truth, my greatest desire was to do this kind of thing with fictional characters, but now I just realized that it's quite exciting to do it with someone so young hahahah"

"Izi, I want you to suck Frisk, this child that is in my lap" Izi was soon surprised by his master's request and soon questioned "I'm not a pedophile like you, you bastard" Izi responded bitterly. Aguru stopped caressing the boy and immediately replied, "I didn't ask what you are or aren't, that was your master's order, s-la-v-e." He spoke provocatively.

Izi just sighed and swallowed. He wasn't going to do this because he wanted to, he would do it because his master told him to, so it would be okay since it wasn't his will to do it, but even so, he felt uncomfortable doing this kind of thing with someone so young.
He cautiously brought his face closer to Frisk's small member, letting the wind of his breath fall on it until he took it in his mouth.

The member was much smaller than his master's, which was to be expected for a 10-year-old boy's penis. He closed his eyes and then began to carry out his master's order.

He glided from the base to the tip of Frisk's small, childish member, feeling a slight mix of guilt and excitement he never thought he would feel, even though he was originally a demon. As he licked the small penis, Aguru put his hands inside Frisk's coat and then began to caress Frisk's nipples while Izi sucked on him.

The little child's body began to spasm involuntarily from the stimulation he was experiencing while unconscious, and little by little, involuntary moans began to escape his beautiful, youthful mouth. They continued until Frisk's vision began to clear. He was finally awakening from his initial sleepy state. As he woke up, he was astonished by the situation he found himself in. One person was sucking his private parts while another held him from behind while caressing his nipples? What the hell was going on!

"Wh-who are you guys!? What are you doing?!" he said, somewhat suspicious and surprised, while the pair simply didn't stop. Aguru smiled when he realized the boy was awake. "Look, it looks like Sleeping Beauty is finally awake, hahaha. How was your night's sleep?" Aguru replied sarcastically before Frisk began to struggle in his lap, causing Aguru to remove his hands from his coat to hold his legs and spread them, immobilizing Frisk.

"Calm down, little boy, what's all the fussing about?" Aguru said ironically as he held the boy who was trying to free himself from his grip. "L-let me go now!" Frisk exclaimed as he continued to try to free himself.

"Look, I always thought you didn't express emotions, you know?" Aguru spoke ironically. "Let's see... what if I do..." Aguru used his stealing ability, but not to steal the ability, but to steal Frisk's physical strength. Frisk's body weakened as he became more frightened at not being able to move.

Aguru threw the boy face down into the flowers while cleaning his own hands and looking at the fallen Frisk. "Look, it seems my ability isn't limited to just skills." He said, looking at Izi with a simple smile on his face and an ironic tone in his voice. Izi just remained silent with his arms crossed. "What?" Aguru questioned Izi, who had a slightly irritated expression.

"You made me do-" Izi's answer was cut off by the voice of Frisk, who was lying in the flowers. "Who are you?" he exclaimed, trying to muster the strength to move. Aguru just crouched in front of him and responded sarcastically and mockingly, "That's none of your business, kid." He lightly smacked Frisk on the head, who reacted by closing his eyes as a natural reaction of the body. "You're much more expressive than I imagined... (in the game he seems to always be neutral about everything)" He argued while thinking to himself (Is this the right universe? Yes, of course it is. Alternate versions of Undertale usually change Frisk's clothes)

"But anyway..." He said while caressing Frisk's face, who immediately blushed with embarrassment. Soon after, he began to caress his own member over his pants. Frisk and Izi looked at that a little suspicious of Aguro's attitude

"Well, because you were a bad boy raised..." Aguru said while sitting on top of Frisk's legs and opening the boy's buttocks, revealing his small and young 10-year-old ass. Frisk was stunned by those words, he was completely lost in that situation, he thought it would be just another reset that he would do among so many, but even in an infinity of resets that he had already done he never saw any of these people he was seeing now

"W-what are you talking about?" he stuttered as he felt Aguru's hands squeezing his buttocks leaving his anus exposed. (I know, I just have to reset! If I reset I can try to wake up before they arrive, maybe they will even disappear!) and so Frisk did, he tried his soul's determination ability, but... nothing. (What? It's not working!?) Frisk's heart raced with nervousness while his mind filled with despair at not being able to use his reset ability

"Aguru!" Izi raised his voice as he rested his hand on one of his master's shoulders. Aguru just looked slowly at the traa, looking at Izi who had a serious expression on her face.
"You really intend to do this to a child? She doesn't have the body prepared for this kind of thing!" Izi exclaimed, looking into the eyes of her master who only listened to the words in silence. "Not to mention that after doing this there will be no turning back, you're going to ruin this boy's life!" Izi spoke with regret, waiting for some answer from her master.

For a moment Frisk had felt relief thinking that the words of that pink-haired young man would change the attitude of the other with black hair, but the reality was quite different... "And you think I care?" Aguru replied, slapping Izi's hand away, taking it from her shoulder. "You're very petty for an incubus, you know that, Izi?" He spoke, resting his hands back on Frisk's buttocks. "I don't care if he's ready or not, I don't care how he'll be afterwards, I'll simply make him like this. He'll be my new pet, just like you are." Aguru spoke, breaking all expectations and filling Frisk's heart with even more fear.

Izi looked at him with a frightened look as he spoke in a lower, more reclusive tone. "You... look like the other demons..." He looked at Aguru and saw the reflection of the hell that was his home. "... you are definitely my master." He opened a simple smile as he held the hand that had been slapped by Aguru.

"Great! Now sit down and watch my new pet being created." After saying this, Izi sat next to him, and soon after, Aguru began to bring his face closer to Frisk's butt. "W-WAIT A MOMENT!-" Frisk's speech was interrupted by an unexpected sensation. He could Feeling something wet and soft passing through his ass,

Aguru began to lick the boy's small, youthful anus. Frisk didn't know how to react; this was the first time he'd felt this in his entire life. Feeling someone licking him in such an intimate place, perhaps even more intimate than the place Izi had been licking him a short time ago. Frisk's only reaction was to tighten his grip on the flowers he was lying on as he felt that tongue pass through his anus. "W-wait~..." was the word he spoke before blushing even more and letting the line out as his abuser's drool left his ass moist with a little saliva.

It didn't take long for Frisk himself to become aroused by the unwanted stimulation; his young member began to grow slightly more erect with each lick he received. Noticing Frisk's erection, Aguru caressed the child's small penis, who in turn widened his eyes again in surprise at having his intimate part massaged.

Aguru pulled his face away from Frisk's ass and milked it lightly. "It seems you've finally gotten excited, huh?" he said with a mocking smile on his face as he looked down at the boy in a tone of superiority due to the circumstances.

Frisk said nothing, just accepted the embarrassment quietly while still trying to regain the strength to move. Frisk's soul was filled with determination, but it had no power to be used...

While the child tried to regain his strength somehow, he was surprised by something hard rubbing his ass. When Frisk looked back, he could see the abusive self rubbing his erect member against his anus.
The boy looked at this scared and soon asked with some apprehension, "W-what are you going to do?"

"As I said, I'm going to raise you to be an obedient little animal," Aguru replied with a smile on his face as he massaged and spread Frisk's buttocks. "By the way, Izi, would you like to join us... hum?" Looking at Izi, Aguru was surprised to see the young man with pink hair masturbating while watching him abusing Frisk "hahahah look, it seems like you're already having fun in your own way, right?" Aguru spoke with an ironic tone

"it's just... I couldn't... control myself~" Izi replied without stopping masturbating while looking at his master's penis rubbing against the young man's anus. "come on, master, fuck this boy's ass, I can't take it anymore~" Izi spoke in a horny voice without stopping the rhythmic movement of masturbation

"hahaha look at you, it doesn't even seem like you were giving me a lecture a little while ago" Aguru replied while turning his eyes to Frisk "well, then let's begin!" As soon as he finished speaking, he grabbed Frisk's waist and began to press against the young girl's entrance.

"Wait! This won't fit... GGGRRRRRRR!" Frisk tried to argue with her rapist, but he no longer listened. Frisk's words were abruptly interrupted by the sensation of sharp, burning pain coming from her ass. With every inch that Aguru inserted his cock into her small, virgin ass, she felt as if she were being ripped apart, being cut in a part that shouldn't be touched. Frisk's words faded away, giving way to grunts of pain as tears welled up in his eyes. "GGGGHHHHAAAA" was the only thing that came out of the little boy's mouth as the protagonist's cock just kept going deeper and deeper.

On the other hand, Aguru was loving the sensation of penetrating him deeper and deeper. That tiny ass really felt like it wouldn't fit his penis, but he just forced it harder and harder, slowly pushing it in, making everything more painful for his victim. Feeling his cock being squeezed by the child's hole was amazing! It was like the sex toys he used at home to relieve himself, but here he was made of flesh and that, here it was real. Here no one would judge him for committing a crime, here there were no laws to protect anyone. Finally, he would satisfy his desire to rape someone, and why couldn't that someone be as vulnerable as this boy, right?

He thrust his penis almost completely inside the small child while she sucked in pain. "You're quite tight," he said as he grabbed and pulled Frisk toward his groin. He received no response, other than cries and screams of pain.

Soon, Aguru straddled Frisk's small body while closing his mouth with one hand, muffling the child's screams. "You make a lot of noise, you know?" As he closed his mouth, he also indirectly closed the boy's nostrils, who soon began to lose oxygen little by little with each thrust he received.

Izi, in turn, just masturbated with increasing intensity watching his master use the boy's small and fragile body. He was quite excited watching the scene that was taking place on top of the initial flower bed.

The sound of skin on skin began to become more apparent in the cave as Aguru increased the pace of his thrusts, becoming increasingly excited as he abused the boy. Frisk was already rolling his eyes from the lack of air. He couldn't move his body, and even if he could, there was nothing he could do in that situation.

What for Frist should have been just another normal reset ended up becoming a nightmare for people who shouldn't even be there. The last thing Frisk could think of before his mind shut down from the pain and lack of air was why this was happening.

As the boy begged for consciousness, the abuser thrust deeper and deeper while letting out soft moans, until he finally reached his climax using the young man's body. Aguru let out a long moan as he spurted his seed inside Frisk's ass, his penis spasming as he came inside such a tight asshole. It was simply an indescribable sensation.

"Aaaaaahhhhh~ how delicious!" He moaned as he finally released the child, making her fall forward completely unconscious. The ex-virgin ass was completely broken by his abuser's cock

"I can't take it anymore either~" Izi spoke as he approached and ejaculated on the unconscious Frissk's body, jets of sperm sticking to the unconscious child's hair.

"That was actually quite fun" Aguru said as he looked at Izi ejaculating on the body of his new toy. He approached the purple-haired boy and brought his face closer to his "it seems your demonic nature spoke louder, huh?" he said with a simple smile, Izi in turn didn't respond, just nodded, blushing and then receiving a kiss from his master. Ambus kissed on top of Frisk, who was still completely unconscious on the floor.

Aguru got up and put his penis back in his pants. "Dress the boy again and clean him as best you can. Let's continue our way and take him." Izi nodded and soon did as ordered.

Ambus followed the path of the ruins while Izi carried Frisk on her trapeze. The smell of sperm she saw from him still slightly excited him, making him massage his own member from time to time as they walked. As

they walked, something the protagonist expected happened: an event, a meeting. Right in front of them was a flower with a friendly expression on its face.
"Hello friends, welcome to the ruins ^^" It spoke with a happy and friendly expression.


But Aguru knew that it was not trustworthy, but even so, he decided to play the game of the little flower that would soon betray them.
"Nice to meet you, little flower." He said with a sarcastic smile on his face, knowing exactly what next steps I would take from then on.

Notes:

I know Frisk was originally created without a specific gender, but to decide I simply rolled a virtual die, if it landed odd it would be a boy and if it landed even it would be a girl, and it came up even lol
Well, I hope you enjoyed the chapter ^^
