SI x Megumin

Summary: A young man died and somehow ended up on Aqua's side of the multiverse. After getting his own cheat power, he proceeds to break the "game".

Out of all the cheats I could get, the one I picked is definitely not one of the more powerful ones. Still, it's one of the ones with the most potential. One can even say it has limitless potential depending on how you use it.

The Cheat I'm talking about is called Skill Manipulation. Like the name suggests, it allows me to manipulate skills. It gives me two main abilities. The first one is to Reassign Skill Points, essentially allowing me to "unlearn" a skill. While that is broken by itself, especially once you get to the higher level, it's not enough for this ability to be considered a "cheat power" in this world.

What makes it a Cheat is its 2nd ability, the ability to Fuse Skills. This allows me to possess virtually an unlimited number of skills if I care enough to keep on relearning the skills I fused. Of course, this is assuming I have the Adventurer class that allows me to learn any skills.

With just these two abilities, I managed to cheat my way around the power system and gain virtually unlimited power.

It all started when I had the bright idea to fuse the skills Mentor from the Teacher class, Copy Action from the Mime class, and Steal from the Thief class. Mentor allows a person to teach another person a skill over a period of time without needing to spend a Skill Point, Copy Action allows a person to mimic another person's action, and Steal, like in the anime, lets me steal a random object from another person.

These three skills combined grant me the skill, Intuitive Aptitude, which gives me the ability to copy ANY skills. I don't even need to use skill points to learn them. The only limit it seems to have is that I can't have two of the same skill at once.

This allows me to save my Skill Points for when I want to buy super rare skills in the future that I can't find to copy. Of course, not that Skill Points matter to me anymore since I can continuously fuse weak skills into OP skills. Examples of such skills are:

Damage Immunity: which contrary to its name, "only" makes a person immune to 99.999999% of ALL incoming damage.

Omni-Drain: allows me to drain anything from the target, from things like health, mana, lifeforce, to even stats.

Danger Detection: It has a long description but can be summed up as Spider-Man's spider-sense. It almost never procs since nothing short of literal divine intervention(aka, other cheats) can pose any danger to me.

And these are only three of my more powerful skills. My favorite skill is definitely Omni-Drain. With it, I maxed out all my stats, which I found out is 999, by absorbing them from enemies I defeated.

Once my stats maxed out though, I created a new skill that recently became my new favorite, Limit Break. By sacrificing my Life Force, which I can regain by draining them from enemies, I can break the limit imposed by the system/world and according to Eris that time she visited me when I first used the skill, Limit Break pushed my power to the level of a God. Not a God like Aqua who had her divine power sealed when she was sent into the world but a fully powered God.

Oh right, did I mention that I'm still level 1? Because I'm still level 1. I didn't see the point in leveling up since I can become stronger without leveling up. Plus, I think it's funny when people see my level and underestimate me then are unable to damage me in any way. Let's just say the fight with the Demon King was fun and not in the battle maniac way.

With my adventure over in a month, I headed back to Axel and basically retired. I didn't publicize the defeat of the Demon King though so all the people know was that the Demon King was defeated by an unknown hero. The reason being, I have the power to live life however I want, making myself famous will only get in the way of that. I rather live like a "normal" person otherwise it'll be hard for me to enjoy moments like right now.

I give Wiz a kiss on the cheeks and slap her perky, naked butt. She's currently bent over the counter with her dress rolled up, her panties missing, and fresh cum leaking out of both her holes.

"Thanks for the help, Wiz. I'll make sure to come by again soon." I tell her cheerfully as I zip my pants.

"Y-You're welcome." She says with a blush as she pulls down her dress.

I "met" her after I returned from my trip to deal with the Demon King. With a bit of magic, skill, and some good old seduction techniques, I manage to turn her back into a human from a lich and convince her to repay me by "helping" me deal with my lust. It took a bit of convincing but I can't say I'm not satisfied with the results. We can be said to be sex friends now but can tell Wiz is developing a little crush on me.

"See you later. Oh, and call me if you need anything!" I tell her before leaving.

Wiz watches me leave happily, her cheeks still pink from our little "session".

A few hours later, I arrived at the house I bought. It's a nice, average-sized home located in a quiet neighborhood near the edge of town. This is the place I've called my home ever since I moved to Axel.

The moment I step inside, I notice a pair of red shoes by the door and the hidden key having been used. I smile to myself as I walk toward the kitchen. There, I see Megumin stuffing her face full of food.

"How could you eat so much in one sitting?" I ask, sitting across from her.

"I'm trying to make up for lost time! I haven't eaten properly in days!" she exclaims.

I literally pick her off the street one time when she was starving and helped feed her. Afterward, I told her about the hidden key I have and that she was welcome to my kitchen anytime. With how much time she spent here, it's like I all but adopted her.

I sigh, "You know that's not how it works, right? Eating too much will only make you fat."

"But if I don't eat enough, I won't be able to grow bigger! It's not my fault if my boobs aren't big enough yet!"

"They're fine as they are, Megu." I pat her head.

She pouts, "No... they aren't... They're so small, and I want them to be bigger..."

I laugh, "Bigger than what? They're already as big as a normal girl's, plus you're still growing."

"Yeah, but I want mine to be bigger than hers! And no matter how many times I eat, they just stay the same size!" She whines and pulls down her shirt to show me her chest.

"What about this?" I ask, putting my hand on her breasts and squeezing.

"Ow! You squeezed too hard!" she complains.

"Aren't they bigger than before?" I tease.

"Well yeah, but not that much..."

"Well, why don't we continue the massage then? Since that seems to be working. If we keep massaging them, they might grow even more." I suggest.

"I thought you'd never ask." She says, getting up from her seat and walking over to sit on my lap with her back pressed against my chest.

With her shirt still down, I start groping her breasts once again. Her skin feels soft under my fingers and her body temperature is surprisingly hot.

"Mmm..." she moans, closing her eyes and leaning back against me.

After a while of rubbing her breasts, Megumin opens her eyes again. "I can feel something poking my butt..."

"That's because you're sitting on my dick," I reply, leaning closer to whisper in her ear.

"Oh..." she says with a flustered look but doesn't move.

I lean forward, my lips brushing her ear. "If you want to see it, I can take it out for you."

"D-Don't talk in my ear like that!" She squeals, pushing away from me.

I chuckle, "Your ears have been feeling sensitive lately, haven't they?"

"No! That has nothing to do with it!" she protests.

"So, do you want to see it?" I repeat, teasingly all the while continuing to grope her.

"N-Not really..." she stammers.

"Do you mean, 'no'?" I ask.

"Fine! Yes, I want to see it." She snaps before realizing what she said and blush.

"See what exactly?" I tease.

"Your d-dick. Your penis, whatever you want to call it." She admits, blushing bright red.

"Okay then." I lift her up with one arm and using my other hand, take off my pants before turning her around and sitting her on my lap again.

"It's so big..." she gasps, looking down at it.

"It can get even bigger. Do you want to see that?" I ask.

Megumin nods, staring at the tip of my cock.

"Then you need to touch and stroke it gently like this." I say, guiding her hands onto my cock.

"H-Huh?" she asks, looking up at me.

"Just stroke it slowly. Don't squeeze too hard or move too fast." I instruct, and she starts stroking.

"Uhm... it's getting bigger... and harder," she mutters.

"Keep doing it." I tell her as I grab her breasts and start kneading them again.

"A-Ahh..." she moans softly.

"That's good. Keep doing it like this." I encourage her.

As she continues to stroke me, the tip of my cock swells and begins leaking pre-cum onto her hand.

"Wha—?"

"Don't worry about it, that's a normal reaction when a guy starts to feel good," I reassured her.

"Oh... I'm making you feel good?" she asks, looking confused.

"Yes, how you feel when I massage your breasts. It's the same thing." I explain, looking down at her as she strokes me.

"Mmmm..." She moans as she focuses on the feeling of her breasts again, "I-I guess that does feel good."

"Then let's keep going like this," I say, moving my hands back to her breasts.

"Y-Yes!" she replies enthusiastically.

We continue like this for a while until I can feel myself getting ready to cum. I move my hand to her side to hold her in place as I cum. My cum shoots all over her stomach with some even reaching her face, and Megumin lets out an adorable yelp.

"Eeep! What's happening?!" she exclaims.

"That's what happens when a guy feels really good. People call it sperm or cum and if it gets inside you, you can get pregnant." I explain, trying to sound casual about it.

"Oh god! Some of it went into my mouth! Am I going to get pregnant?!" she panicked.

I laugh at her, "Hahaha, no. I need to release it deep in here-" I said, moving a hand down and rubbing against her pussy through her clothes, "-for you to get pregnant. Even then it's not likely unless you do it a few times."

"Ahhh...!" she gasps as I rub her wetness between her legs.

"T-that, that feels even better than when you massage my boobs." She exclaims.

"Do you want to feel even better?" I ask, glancing down at her.

"Huh? Y-Yes! Please, yes!" she replies.

"Well then," I grab her and stand up, setting her on top of the table. I lift her skirt and pull off her panties as she stares at me with wide eyes.

"Wah- You never said anything about taking off my panties!" She exclaims in panic and quickly uses her skirt to cover herself with a flushed face.

"I have to remove them if you want to feel better. Otherwise, this won't work." I explain.

"B-but-"

"Megu, do you want to feel good or not?" I cut her off and asked.

She looks down at the ground, "Y-Yes... I do... but..."

"Then move your hands so I can get to work. Besides, you have already seen mine, there's no need to be embarrassed about me seeing yours." I remind her.

"A-alright." She agrees. With a deep breath and a red face, she moves her hands.

"That's right. Just like that." I tell her as I spread her legs apart, exposing her pink pussy.

"O-Oh...!" she gasps in surprise as I run a finger along her slit.

"Just relax, let me do the work," I tell her.

She nods, biting her lip nervously.

I position my fingers on either side of her clit and begin to rub it. As I do, her body tenses up in anticipation.

"That's right, just like that. Good girl. That's it." I whisper encouragingly as I apply pressure.

After a moment, her breathing becomes ragged and her hips start to rock slightly.

"N-No way..." she whispers, her cheeks bright red, "It feels so good..."

"I know and it'll only feel better from now on. Relax and enjoy it." I say softly as I continue rubbing her clit.

Her body responds by shaking and quivering, her hips buckling as she pants. Her lips part and she makes a low moan as she squirms on the table.

"Ah... Nnnggh...!" she cries out in pleasure.

"That's it, cum for me." I tell her, putting more pressure on her clit.

"Ah! Ahh! Gyaaah!" Megumin screams as her orgasm hit her. Her back arches and her whole body shakes and quivers. She's jerking and spasming uncontrollably, and I can see her juices running down her legs.

"Woah, be careful!" I call out, grabbing her shoulders to keep her steady. Her body goes limp and her head falls forward as her orgasm subsides.

"It... it was... amazing... almost as good as explosion..." she breathes, letting her head fall back onto the table.

"Good, I'm glad you enjoyed it. Now, it's my turn." I say, pulling her ass to the edge of the table.

"Wha- A-are you doing?" she asks, looking up at me.

"Making both of us feel good together." I spread her legs and pressed my cock to her pussy. I push slowly, feeling her wetness and warmth.

"Nnngg!" Megumin moans as I enter her.

"You're so tight. It's wonderful." I tell her as I slide deeper into her pussy. I look down at Megumin and her eyes are closed, her face red as she bites her lip.

I thrust in and out of her as fast as I can without hurting her. She's panting and moaning loudly in pleasure. Her pussy is clenching around my cock and I can feel how hot and wet she is. I put my left hand on her hip and use my right one to rub her clit gently.

"Haah... haah... Haah...!" she whimpers and moans as she orgasms again, her hips buckling.

As she cums, I feel her inner walls contracting around my cock. Her pussy squeezes me like a fist and I feel myself about to cum.

"Ahhh! Fuck! I'm cumming!" I quickly pull out and spread my seeds all over her. I spray ropes of semen, splattering her stomach and chest with jizz.

After I finish cumming, I grab Megumin again and shove my dick inside her pussy again. I thrust hard into her as she screamed in pleasure. With my endurance, I won't be satisfied with just cumming once or twice, and to make sure Megumin can keep up with me, I cast Full Heal on her, making her recover to peak health.

"Haha... mmm...!" she moans as I fuck her, her hips buckling and her breasts bouncing.

The sight of her tits swaying and jiggling in front of me drives me crazy, and I pound my cock into her harder and faster.

"Ah... haah...! Mmhn...!" she pants as another orgasm hits her.

"Mm... haah..." I grunt as I climax, spraying my seed all over her again before repeating what I just did and fucking her again.

This went on for a while but even with Full Heal, Megumin's mind can only take so much pleasure before she passes out but I'm nowhere near satisfied.

With a sigh, I cast Clean on the girl and use the skill, Contraception on her to make sure she doesn't get pregnant even if I didn't cum inside her(mostly because I don't want to scare her) before teleporting her to my bed. With that done, I head back out to find Wiz again. She's the only person who can keep up with me so far and only thanks to my Full Heal.
