Shauna didn't want to be here.
She hated parties, she hated big crowds, and she hated you. Let's be honest, Shauna hated a lot of people, but there was just something about you that she despised with every fiber of her body —it was probably the fact that you liked Jackie and shamelessly flirted with her 24/7—. She knew she couldn't be mad because she wasn't Jackie's girlfriend, yet she was dying to be and wanted nothing more but to make the girl realize how she felt for her. She would do anything for Jackie, which is why she was attending this shitty party for starters.
But what she would not do is watch you steal her girl.
She didn't care if she caused a scene, she didn't care if people found out about her sexuality, she didn't care if Jackie got mad —the cheap alcohol in her system wasn't allowing her to think clearly. With wobbly feet and a fuzzy mind, she stood up from where she was and approached you. Shauna pushed you away from Jackie and exclaimed a hash 'What the hell do you think you're doing!', her words slurred yet understandable. It didn't take long before your loud voices overpowered the music and Jackie knew people couldn't see this, so she gripped your arm and Shauna's and led the two of you upstairs.
Jackie didn't know why but she didn't want to stop whatever was going on, which is why she permitted the two of you to keep—… fighting over her. In the safety of whoever's room this was, she watched the two of you yell and shout profanities at each other; her body warming up with an unknown feeling at the sight of two stunning girls causing such drama over her. Yet she knew her best friend wouldn't hesitate on physically attack you so she decided to intervene, stepping between the two of you and placing her right hand on your chest and her left on Shauna's.
"Okay, okay, that's enough!" She quickly said, lightly pushing both your chests to create more space between the two of you —though she couldn't hold back the blush from spreading on her cheeks—.
