“Ohhh! Ohhh! Yes! Fuck me, hard babe! Ahh! Shit!” Luna moaned as she felt the cock of Brian move so hard and fast inside her wet cunt. “Yes! Just like that, babe! More! Ahh! Fuck me more!” she hissed in pleasure as her head was spinning in so much sensation she was feeling as of the moment.

Luna’s eyes are closed while her hand clings to Brian’s shoulder as he goes deeper and deeper inside her, and the latter just continued thrusting his manhood as if he has no girlfriend to take care of and as if he was not fucking his girlfriend’s sister.

Luna, the one Brian is fucking as of the moment is no other than Ariana’s sister—his girlfriend for almost 3 years. He met Ariana Bruce in a business meeting, and she found her really stunning and beautiful that’s why he courted her, and after almost 4 months of the courting phase, Arian finally said yes, and they dated officially.

But things started to change, and Brian was getting swayed by Luna Bruce, Ariana’s sister, whom she met just a week since he started courting Luna. Brian already felt that there is something wrong with how Luna treated him and he always noticed those subtle touches from Luna, although he tried his best to not give in to the temptation, she was giving him.

Until one day, just two weeks after officially dating Ariana, he went to their house only to see Luna alone, and Luna told her that Ariana went out to buy some groceries, but the truth was Luna knew that Brian was coming so she ordered Arianna to buy some groceries 1 hour away from their house.

And that was when it all started. Luna and Brian stayed fuck buddies without Ariana’s knowing and now... they were fucking and enjoying each other’s bodies at Bruce's residency without thinking that what they were doing was horrible and unforgivable.

“W—Why do you still have not to dump, Ariana? Ohh! Ahh!” Luna managed to ask that despite the fact that she was losing herself because Brian keeps fucking her wet cunt. “Uhmm! Ahhh! Y—You should break up—Ahhh! So, g—good… Shit! Brian! Break up with Arian now! Ohhh! I will be yours! I will take c—care of you and always warm your bed… Hmm… Ahh!” she moaned lustfully while saying those words.

But Brian did not say anything, instead, he pulled Arian’s legs to pound her cunt even harder, making both horny individuals writhe in pleasure and filled Ariana’s room with their moans. But even though they’re in between doing sexual activities, Luna kept begging Brian to break up with Arianna and make both of them officially dating.

For Luna, she hated Ariana from her soul to her bones. She has loath Ariana ever since she was adopted by her parents. All the things that were supposed to be for Ariana, she steals until she saw the pain in Ariana’s eyes. And now, she will not stop from fucking Brian until he gives in and chooses her over Ariana.

“Ohh! Ohh! Yes! Yes! Brian! You fuck so g—good! Ahh! More! Ahh! Ahh!” Luna groaned wildly, even more, when she felt a huge sensation building and ready to come out any time in her womanhood.

“Ohhh! L—Luna! You are so tight! Fuck! Ahhh! Shit! Your pussy feels so good. Ohh!” Brian hissed while his eyes are closed and he thrust faster and deeper inside Luna, making the couch crumble and shake, but he did not care.

“Ahhhh! Ohhh! I am cumming, Brian! Shit—Ahhh!” Luna moaned vociferously as her legs started shaking in too much pleasure. “Ahhh! Ohh! Please! Break up with Ariana and be with me! Hmm!”

And in just three more strokes, Brian and Luna both reached their climax and they moaned together not caring if someone could hear them, and the two horny individuals did not even hear the opening of the door and the step of someone they betrayed walking towards them with so much coldness radiating in her face.

……….

Arianna’s POV

“I will look for a way to get you treated, Mama Kara. I won’t let anything bad happen to you. I promise,” I whispered as tears are falling from my eyes while holding the hand of my unconscious Mama Kara.

Mama Kara is the caregiver from the orphanage where I came from before I got adopted by Bruce's family. She was the one who take good care of me in the orphanage, spoiling me, and loving me. Because of that, I treated her as my biological mother and when I got adopted, I had no choice but to leave the orphanage and go to my foster parents’ house. But I always make sure to visit the orphanage and Mama Kara all the time.

Seeing Mama Kara lying on the hospital bed unconscious is so heartbreaking and I will do everything for her. She has given me her best before, so now, it is my turn to take good care of her. I will do whatever it takes to get her operated on and treated, even if it costs me my life.

And in my situation right now, the only people that I could run into are my foster parents. The Bruce family is so rich, and they adopted me for an unknown reason. They gave me everything from clothes to luxury, but I never received any love or warmth from them. And up until now, it is still a mystery to me why they adopted someone like me when they already had a daughter at that time and it was Luna.

I looked at Mama Kara again before I decide to go home and tell my parents about the favor that I will be asking them. I am just hoping for a positive result even though I am not close to them, and they are not that ‘parent-material’ towards me.

I stepped out of the hospital exit and went to the parking lot and drive myself home. Upon driving, I am feeling nervous all of a sudden, and the more I am near our house, the more I feel this nervousness.

‘What the fuck is this uneasy feeling?’

Until I reached the gate and parked my car in front of our house, I still feel uneasy, but I tried to shrug it off. It is already 9 in the evening, and I know that my parents and sister are already home.

I opened the door, and it is not new to me that no one greeted me because this house really screams coldness all over. I am sure that my parents are in their room already while my sister is probably enjoying herself in the pool because Luna is a swimmer and she usually practices at night.

I walked upstairs because my room is on the 2nd floor of the house. Upon walking to the corridor of the 2nd floor towards my room, I could hear subtle sounds that I could not pinpoint where are those coming from.

What the fuck is that sound? I frowned in curiosity, but I continued walking and the more I walked towards my room, the more the sound becomes clear, and those sounds are making me nervous and anxious.

When I am just 2 inches away from my room, that is when I realized that those sounds are the voices of a man and woman doing something nasty. But I do not want to conclude anything yet, because those voices are so familiar to me.

Nervously, I walked closer to the door of my room and bravely put my right ear on my door… only to get frozen by what I heard. My mind went blank, and I could not even say or move my hand to open the door of my room. I feel really lost and dumbfounded.

Those groans and moans coming out from my room are so familiar because those are the sound of two horny people fucking each other. I leaned my left ear o the door even more and from where I was standing, I could hear more clearly the moans from my room.

“Ohh! Ohh! Yes! Yes! Brian! You fuck so g—good! Ahh! More! Ahh! Ahh!” Just like what I have expected… that familiar voice of a woman was no other than my sister, Luna.

I clenched my fist and my jaws tightened, especially when I heard another familiar voice, coming from a man whom I have loved for three years.

“Ohhh! L—Luna! You are so tight! Fuck! Ahhh! Shit! Your pussy feels so good. Ohh!” Brian moaned back and that was when I felt more drained. How could he do this to me?

I did love Brian with all of my heart. I was already planning my future together with him, but how could something like this happen to me? Was I not enough? Was I not being able to satisfy him in bed? Was my pussy not enough to fuck with? Fuck! What the fuck did I do to deserve this betrayal?

But all in all, I had to act cold and nonchalant because, in that way, I would survive this cruelty of broken trust.
