This is really feeding into the sister fetish/kink that I have!
I adore the "outfit" and fun young woman she is, but she is like a sister in my opinion.

I have imagined her saying "big brother/bro" please teach me how to play this game. Or begging me to play with her saying "big bro play with, I just want to spend quality time with you" also "big bro if you win I will let you kiss my kitty but if, you lose....".
