Y/N P.O.V~
I'm going to feel so bad, I can't believe I'm doing this with her brother, I move my body back and forth to pleasure us both. Billie was never here, she was always out with her friends and she would flirt with them and expect me not to get mad but whenever I do something like that I'm a 'whore'
"Fuck Y/N your doing so good babygirl." Finneas says as he looks up and finally stares into my eyes. It felt like the world just stopped and went into slow motion, the room door opens revealing a Billie staring down at her phone asking for Finneas to watch something. She looks up and sees me on top riding him.
We didn't even notice her standing there, mouth wide open staring down at me. Finneas yanks my hair and fucks me faster than before. I scream and scream his name so loud that he came in me fast. Shortly after I cum on his stomach, we look up smiling and breathing hard. Then I noticed her...standing there with so much hurt in her eyes.
"How could you fuck my brother behind my back, I fucking loved you all this time just for you to go and fuck Finneas?" Her voice gets louder by the second, tears dropping from her eyelashes and onto her face. "I see how it is, keep that same energy." Then she walks out.
I get dress and run to her room, "BILLIE YOU CANT GET MAD AT ME! YOU FUCKING CHEATED ON ME FIRST WITH MY COUSIN BILLIE, MY FUCKING COUSIN!" I slam her room door shut and yell even more. "YOU DONT KNOW HOW MUCH YOU HURT ME. YOU HURT ME THE FUCKING MOST!" I cry harder this time. I left Billie speechless after that, "Y/N I'm sorry I didn't mean to hurt you like that but I understand now, I just feel betrayed by my own brother.
"Billie it wasn't his fault I told him to have sex with me because I was missing you way to much." She looks down and thinks hard. I was tackled down and kissed mad hard by her. Billie slides her hand down my pants and rubs my clit hard. "Billie..." I breath hard and throw my head back from all the satisfaction I was dreaming of.
