Fulfilling my Lustful Fantasies

-Lucielle POV-

When I woke up the following day, it was still dark outside. The temperature is starting to get low, due to the fact that the year is about to end. I was still under my blanket, when I looked to my side and found my son sleeping peacefully.

I just went full liar on Celine, preaching and telling her to keep her hands off her brother, yet I... Sigh, I think I'll have to cook her favourite food for quite some time, just to apologize in a way. But still the most important thing is that I just entered forbidden relationship with my son.

I mean even before, our actions were already forbidden, but he didn't know about those back then. Now he's well aware of what it is, but he still agreed. I had his 'consent', and that's the big difference. Usually after such sessions, I would be rolling over in guilt and staring into nothingness. But now contrary to feeling bad, I feel refreshed and satisfied, without such heavy emotions on me right now and the fact that my biggest worry all this time was now gone. I looked to my side again and observed him so defenseless as he slept.

"Sigh... it's a good thing I held back after the first one." I said in relief

My desires really got ahold of me the first few minutes, but luckily I was able to rein them in. Otherwise it might not be healthy for him to have such a warped view of sex, since he will have that as his reference.

I looked at him sleeping, completely oblivious to how his Sister felt towards him or to how much sleep I lost before, thinking about how to talk to him about it.

"Really... How bad of you." I said

I crawled on top of him, with my arms and knees at the side of his body. Right now he was sleeping, if I were to-... Nah, forget it. Instead, I just observed his sleeping face. It was still pretty dark outside, so he wouldn't be waking up anytime soon. I had some things to think about as well.

I thought back to what we did last night. It was quite the mess, I remember going from what I felt was the depths of hell to pleasures of heaven in a matter of minutes. Really, how could something that was so bad suddenly turn around in my favor so quickly. But more importantly, I just crossed the final line with my son,

No, just saying that I crossed it would be an understatement. I sprinted across the goddamn line, like it was some sort of race, and when it was done, I went back just so I can cross it again. I thought back to how I was basically ravaging him while he was panting under me so weakly, and- No stop, Don't think about that.

I had to stop myself, since I felt myself get excited from remembering his weak and loose face under me. Uggh, it was his first time. I should've thought about that and should've been more gentle with him.

But still, when he just forgave me like that, I wanted to 'punish' him in some way. He made me worried about his future all this time, and he was just gonna end it with him acting all cute infront of me. He even said that I could do 'anything' to him and he would keep it a secret. Like... wasn't he basically asking for it?

At first, I was mad about how can he say such things so easily, especially after how I just thought him about the importance of sex, and just wanted to scare him so he would know better. But he didn't regret it nor did he ever take back his words, he just bit his lips silently as he let me do whatever I want. So I got more and more daring with my actions.

When I licked his cheeks and whispered into his ears, I could see his face change in shock as he realized that I wanted more than just some 'cheering up'. I remember his face when he realized Mama wasn't as pure as he thought, and even then he didn't take his words back and just let me do anything. The way he looked up to me so nervously, like he just saw a completely different person just... riled me up.

When I thought about it last night, it's not that he will say those things to anyone just because he likes them a little bit. He said those words to me, because well... it was me. He had enough trust in me that he can say things like that without worry and that just made him all the more precious in my eyes. He was so precious, so pure in fact, that I just wanted to taint him. It was a desire that grew on me this past few years, constant teasing without any proper release.

I looked at him sleeping under me and thought to myself. He was just inside me a few hours ago, he didn't care that it was the same hole that gave birth to him as he released everything into me. Good thing it was a relatively 'safe' day, otherwise I wouldn't have let him cum inside me like that. I also used my water magic to wash it out, since things would become a mess beyond repair if I got pregnant with my son's child.

I looked at his cute ears, he had quite the reaction when I nibbled on them last night. I lowered my head towards the tip of his ears before nibbling on them lightly and I felt him shiver under me.

"Ah...no..." he voiced out while sleeping

Will I stop what I'm doing with my son? Even though I told myself countless times before that it's wrong and that I should stop, I went and did it again anyways. I'm already past the point of feeling guilty and just accepted that I'm the one responsible that our relationship became like this. Even before it's already a temptation that I can't resist, now that I have his permission though, it's just too sweet of an offer.

"It's your fault that Mom is like this..." I wrongly complained, before getting off of him

'I should get the day started already' I thought as I got off the bed and readied myself for the upcoming day.

-Maelriel POV-

When I woke up, the sun was already rising and Mom was already out of the bed. I was in high spirits as soon as I woke up, when I thought back to me being able to enjoy my Mother's beautiful body. I could enjoy the beautiful bodies of my family, I got out of the bed with such thoughts, as breakfast should be served around this time already.

I was curious to how Mom is right now. Up until now she would always look so out of energy after our sessions, so I was curious to how she would be now. I went downstairs where I found Mom at the chair drinking coffee while reading some novel like nothing was wrong, and Sis was at the table eating.

"Morning sweetie~" Mom said so casually

"Uhm... Good morning." I replied,

Seeing my questioning look, Mom just giggled before making a 'shush' gesture with her fingers. I nodded and went to the table as well to eat breakfast and found that there were a lot more than usual today.

"You like the food?" Mom asked

"I like it" Celine answered before resuming eating.

I looked at my beautiful Mother and Sister, both thinking that they have their own secret relationship with me that they would like to keep from the other. I wasn't that worried about them revealing it since they have their own reasons why they would want to keep it a secret.

However if in the future, things happen where they decided to finally open up to each other. I wasn't worried about the possible 'small' inconsistencies in the lies that I told them. Unless they have massive balls of steel, I don't think they would actually tell of how the relationship actually started, or more specifically how early it started.

In the rare chance that they actually decided to tell it, then it'd probably be a toned down, more 'socially-acceptable' version of it. I can't see Mom willingly ruin her image to Sis, by telling her that she had me do such things when I was still 'clueless' it. Celine also said something about working hard so that Mom can accept our relationship, so I think she'll atleast spin the story where it will be favorable towards us.

---------------------------------------

Blissful days went on until the end of the year. As I can finally live out the dreams that I wanted when I first thought about reincarnating in a fantasy world. Slowly corrupting my Mother and my Sister, so that they would accept, no willingly chase after having a relationship with me.

During the next days, I enjoyed the fruits of my labor as I enjoyed the two of them in as many erotic scenarios I could think of. I had many fantasies I wanted to fulfill and I wanted to do each of them one by one

One time, when Sis and I were practicing magic near the pond, I suggested to have some 'fun' on the water-

"Ahhn♥ N-No, Riel. S-Someone might see us!" Sis said in worry as she looked around the surroundings

Our bodies were both wet, as we soaked ourselves in water. Sister was currently bent over at the edge of the pond, where the waters reached just around our thighs. I was fucking Celine from behind while I kneaded both of her large breasts.

We already took a lot of naked baths around here, and we were sure that no one visits this area. But the shame of having sex in public, now that she was fully aware of such matters got into her mind. We were both fully naked, and everyone in the village knew that we were siblings. If someone were to catch the two of us, it would really not end well.

"But Sis, you're getting tighter." I said to her as I felt her pussy clamp down on my cock due to her shame

I then held her by the waist as I started pulling her round ass towards me everytime I would thrust inside her. The water around us were splashing around due to our movement, and a loud clapping sound would echo everytime our wet skin would come in contact.

The way her adorable butt would ripple everytime my hips would hit it, just looked so erotic. Her wet hair were sprawled all over her smooth back I continued fucking her from behind. This was something that I will never not like, the pleasure of having my older sister become so meek as she entrust her most precious place to my cock.

"Ahn♥ Ahhn♥ It's deep inside again~" Sis moaned out

"What's deep inside you?" I asked as I grabbed both of her hands which were holding onto the rocks and pulling them

"Ahh♥ Your... Your dick" Sis answered weakly

When she felt my thrusting become frantic, she then panicked.

"R-Riel! Don't! Not inside, okay? It's not safe today, I might get pregnant!" she said as she looked back towards me pleadingly

"Think about our future! We can't let Mom find out yet!" She suddenly spoke

'Damn', don't say such things while looking at me with such cute eyes. She's just so adorable and lovely. Even during the pleasures of sex, she never not thought about having Mom accept our relationship. In the end, I didn't cum inside her. I too didn't want to risk it, for momentary pleasure.

In the end right before my climax I pulled out and have her kneel infront of me, as I painted her face white with my cum.

After we cleaned up, I hugged her and whispered

"I just love you so much Sis."

"I know, I love you too...Let's work hard, okay?" Sis said before kissing me

"It might be hard hiding it for now, but someday we can get Mom to accept of our relationship as well" Sis said as she hugged me back

Such a lascivious lifestyle continued for days, as I indulged myself on the bodies of my beautiful relatives. I would usually sneak out with Sister at the day, and Mom would approach me at the night. It was this kind of life, that I wanted when I first reincarnated into this world, a life full of sinful forbidden affairs.

Mom said that we would be leaving at the second week of next year. I then thought about my beautiful teacher as well, and I couldn't help but wait for the things that would happen to my life in the future
