I was at my brother's girlfriend's house, obvious reasons. He was not home and he was actually out cheating, I knew and she knew. I went over and 'cared for her', 'supporting her' in ways he didn't want to do anymore, I guess. She was sat on her bed, reading a book. I was somewhere Her boyfriend stumbled into the room, a guilty look on his face and hearing he ask if everything is okay, I smirked. He admitted to cheating and yet she laughed and gave a simple 'ok' and went back to reading her book. He asked why she suddenly wasn't mad, she scoffed. That's when the blankets moved, my head perking up from underneath and I smirked at my brother who was now her ex-boyfriend. The look on his face I couldn't tell if he was disappointed or understood, I mean if you cheat and not expect something to happen back then your mental. He hesitantly asked what I was doing and I shrugged "Doing something you can never do." I responded, leaving a frown on his face. My hand slipped to her jaw, kissing her - my brother exiting the room immediately. I got up from the bed and wandered over to him, obviously shirtless. He was about to leave but I had to say something. "She's got great legs, by the way." I spoke, shutting the front door as he left.
