Show her some sisterly love

Ruby gets a cute idea. "Yang, show me how much you love me." Ruby orders as she opens her arms for a hug. Her older sister approaches her and gently wraps her arms around Ruby's slender frame. One hand on Ruby's lower back and the other behind Ruby's head. Before Ruby can react Yang pulls her close as their bodies rub together and their lips lock.

Ruby's eyes go wide as she freezes in shock. Yang's tongue quickly darts into Ruby's open lips as she overtakes her younger sister's tongue with skill and experience.

'WHY IS SHE KISSING ME?!?!' Ruby yells in her own mind. She puts her hands on Yang's shoulder to push her off but hesitates.

'Why... why does this feel so good? She's my sister! But she's a really good kisser. Gah, this is not how I imagined my first kiss!' Ruby continues to argue with herself as Yang passionately expresses her love for her sister.

After a few more minutes of kissing Ruby finally pushes Yang off. "Stop. Tell me why you kissed me?" Ruby asks.

"Because I love you Ruby, you're my adorable little sister. I have thought before that if we weren't related I would ask you to be my girlfriend." Yang responds, a bit more emotion in her voice as she confesses that.

Ruby goes as red as her namesake at hearing that. "You... wow... Yang, when I snap my fingers you will come out of this trance but will now be more openly affectionate to me like what we just did."

Yang nods with a smile. Ruby snaps her fingers and Yang blinks, immediately her movements are more lifelike as she regains her senses.

"Wha? Sorry Rubes, I zoned out there. How about we spend the day together?" Yang asks Ruby with a smile.

Ruby smiles back. "That sounds great sis."

Yang's smile shows more teeth as it gets bigger. "Alright! Just give me a chance to shower first." Her hand goes to Ruby's chin, tilting it up as she gives Ruby a quick kiss on the lips as if it were a completely natural thing to do before she heads for the showers. Ruby gets giddy with excitement at what could happen now that they've crossed this barrier.
