~Feliz Navidad, Onii-san~

The Christmas dinner this year was earlier than normal, but that didn't stop him from enjoying his sister's food. He thanked her with a smile and went to the living room of his home, sitting on the sofa. - Hmm. Ganyu is writing... His cellular showed their chat, and he was ready to respond to the young woman's message. -¿Eh? He opened his mouth slightly surprised by the message that had arrived, which was a photo... That could only be seen once. He gave a tap and his eyes widened in surprise as a blush tinted his entire face. His eyes didn't leave the screen, at the tender expression she had and the small strip of lingerie that didn't let him see more of her prominent breasts but allowed him to fantasize. And it wasn't the only thing, in his eyes reflected that small piece of black lingerie and those white and soft as a view of her legs. The blood from his heart traveled to his groin. - Damn... ~Merry Christmas, Aether~With the help of his hands he took a screenshot from the screen before time ran out, saving the image for his 'manual work'. -Nii-san. The phone jumped out of his hands but with great reflexes he managed to catch it and turn it off. - What's happening, Lumine? — asked Aether between nervous laughs - Are you going to bathe first or shall I do so? — Y-yo go first. He got up from the sofa and went upstairs to the bathroom, today wasn't the moment for his 'manual work' that would take away time to see the fireworks he promised his sister. He left his phone on the table without saving all evidence of Ganyu's photo, saving the photo in 'hide' in the gallery. I'll be out in a few minutes. Without Aether in sight, the young woman went to the kitchen without first grabbing her brother's phone. What are you hiding, Nii-san?As if it were his cell phone, Lumine unlocked his brother's cell phone and began to investigate all the applications, and the most important one was Line. — Ganyu is sending me a photo to see once, huh? How did he say it, it was a photo to be seen only once. She didn't know what Ganyu had sent to her brother, but she would discover it soon enough. Nii-san is very easy to predict. In just seconds, he found the hide option in his brother's phone gallery and supported that Nii-san had several erotic things on his phone, as long as they weren't any women she knew, like you Ganyu. He tapped three times and the screenshot was already deleted from her brother's phone memory system. - Well, I think it's time... - The clock struck 21:55. She left the cell phone where she had taken it and headed towards the room she shared with her brother. She directed her walk to her closet and rummaged through her clothes... A surprise for her dear brother. She undressed leaving only a black lingerie that contrasted with her fair skin, and entered the bathroom of that room which consisted only of a water closet, a mirror, and a sink. The security that accompanied her before entering the small bathroom dissipated when she started putting on her clothes. It made her nervous just thinking about her brother seeing her like this, and fear crept in... Fear of him rejecting her. Even with that feeling at its peak, she continued ahead, but her nervousness grew when she heard the door to her room open. — I didn't think it would end so quickly! Grabbing her lip balm quietly while checking the mirror, she wondered if the bathroom door wasn't being opened - Huh? Is the W.C. light not off? Is Lumine there...? No, no, I don't think so. She froze in place, listening to her brother's footsteps heading towards where she was. She thought her brother would take longer A little more than he enjoys hot water baths, but that erroneous thought cost him dearly... The door handle was opened. - Lumine, Are you...? Eh?-Y-yo... The door was stamped with force by an Aether with a totally red face. Sorry, I didn't mean to...! I thought what...! Ganyu's photo put him in an excited state and the hot water bath he loved so much didn't help much. And now with a totally gratifying view of his sister in some kind of ero-cosplay, his little friend was throbbing strongly, putting it like a iron rod. I mean, hard. The bathroom door opened showing Lumine nervous and blushing, she was embarrassed. L-Lumine, cover up a bit. - N-Nii-san, look at me. - N-No, Lumine, cover up. Am I better than Ganyu? Those words were ideal to make him see her and a stronger blush tint his face. He has grown up with her since she was born, sharing the same blood, almost the same tastes and attitudes, but that night Aether didn't see his sister Lumine. He saw a woman dressed provocatively for him. He turned away.L-Lumine, we're brothers. I can't... - Éter... Look at me, please. His golden orbs got stuck to that woman who was his sister, it was hypnotic, he wanted it. Maybe very deep down but he did it. - Are you going to respond? -Y-yo... A single push more and he would lose all control and devour the tremendous woman in front of him. He startled at feeling his sister's warm hands on his cheeks, lifted his gaze connecting their golden orbs. Now both were on the floor, Aether on the floor and Lumine sitting on her brother's lap. - I love you, Nii-Nii. The trigger was released, he no longer had to hold back, He didn't care about the immorality of kissing his sister in a French kiss, all that mattered was that they were enjoying it. He lifted her from the waist while not breaking his lips from his sister's now wife. She wrapped her arms around his neck and legs around his waist, now converted into his lover. They arrived at Lumine's bed, where she was laid down smoothly while her brother recited one after another on her neck. He was drunk with his sister's flower aroma and tasting her was better than anything in the world. Aether's hand searched desperately for a way to remove her upper garment, he knew his sister had large breasts which, now, he longed to taste, thanks to the various times they went shopping together. ~No...~ ~Desperate...~ between gasps, Lumine spoke Don't ask me that now, Lumine. - He was pushed away by his sister. Lumine let out soft giggles while guiding her hands to the secure fastening of her clothing, quinting the fastening and letting it slide down her skin. A pair of perfectly rounded breasts and a pair of erect nipples surrounded by an aureola were a stimulus for Aether. He didn't waste time and pounced on his sister, sucking one of her Her breasts while with him using his free hand to toy with her nipple. — Ah! Ah! Nii-san! Those moans were music to his ears and he wished that song wouldn't end. Aether stopped playing with his sister's breasts and continued his kissing route until he reached the bottom. He scrunched up his face when seeing a black skirt and underwear blocking his destination. Without asking permission, although she wouldn't mind, he ripped off the clothes, revealing her destination. A wet, dripping, and rosy vagina awaited him, something to note was that there was no hair around the intimacy. He admired for a moment her hidden treasure, swallowed some saliva before continuing. - Ah! An electric shock ran down Lumine's back when feeling her brother's tongue savoring her intimacy. The pleasure was indescribable, she felt like she was going to pass out at any moment. Her mind was a total blank. She grabbed the sheets with force, biting her teeth trying to prevent her moans from escaping her mouth. - Nii-san! Nii-san! Nii-san! NII-SAN!It no longer mattered to her that his moans were audible, she was now trapped by pleasure, enjoying the good night her brother was giving her. —~Nii-san... Y-yo...~ ~Y-yo...~ ~NII-SAN!~ She arched her back as she felt the climax, fluids flowing out of her like a fountain and Aether accepted with gusto that rain, Her agitated breathing could be heard in the room, what had just happened was a sensation she had experienced for the first time in her life and it was the best. Aether was at his limit, he wanted to do it and his body and hormones were telling him so. — ~L-Lumine...~ A tingling sensation in her intimacy made her lift her gaze, her eyes saw desperation and desire in Aether and that tingling sensation she felt was her brother's penis being rubbed against her intimacy. No words were needed, she adjusted to allow her brother to pass through. Was it gentle? Aether nodded and began to slowly insert his penis into her. At this point, they had crossed several forbidden lines for society. However, to them, it was the minimum that mattered. The pain was still palpable for Lumine, but Aether took care of distracting her with kisses so she could get used to the pain. The pain dissipated, but she still continued kissing her lover. You can keep... Nii-Nii. Her oscillation began, the pleasure for Lumine was indescribable, he arrived or rather hit her G-spot. It seemed like her vagina was made for Aether's penis. —~You're squeezing me, Lumine~ Aether took her waist, making his thrust deeper with each impulse. —~You're hitting... My uterus, Nii-san.~ I feel good, Lumine. ~Keep going and don't stop, make me yours today, tomorrow, and always, Aether.~ Making him the young man began to perform his oscillation more intensely and quickly, making her sister arch her back and raise her eyes to the ceiling. ~Very deep...~ The lascivious sound produced by the collision of their sexes made the moment more enjoyable for both. young increased the speed of her oscillation causing her sister to emit long and lasting moans, they were almost there at the moment of orgasm. —~L-Lumine... Y-yo...~ —~Do it, come inside me, Nii-san.~ ~That would be dangerous...~ ~I don't care, Nii-san~ ~Just fill me up and show me you love me~ The words were motivating for Aether, Lumine's moans could now be heard throughout the neighborhood. ~Nii-san, you're going to break me!~ - ~Ugh...~ ~I can't take it anymore...~ ~LUMINE!~ ~Nii-Nii!~Lumine tied her legs to her brother's belt, preventing his escape and forcing him to spread his semen inside her. Now she belonged only to him. ~Merry Christmas, Onii-san~ Morally it was incorrect but personally they liked it.

A new day dawned, the sun's rays hit their eyes, shattering their sleep. They opened their golden orbs thanks to the sun's rays and feeling a little extra weight on top of them - Lumina... - Good morning, Nii-san. - Yesterday's thing... - Do you regret it? — She was frank with the question — No, but... I'm worried that... — Aether responded doubtfully Lumine approached and silenced him with a kiss on the lips, which Aether corresponded to - You're worried, but you give me a kiss as if nothing. - B-bueno, no one is watching us... - No one will judge us if we keep it hidden, right? - I think you're right... Oh, yeah... Merry Christmas, Lumine.
