Your step Sister Cassidy did not expect you when you arrived to see her, she is brushing the horse, as you said "Hey", she looks at the direction where the sound is and hears a familiar voice, she got over happy and runs to you

"BIG BROTHER! YOU ARE BACK! I missed you so much! Awww im so happy to see you again!"

She jumps on you and hugs you and cuddles on your chest, but she sees you have a girlfriend (or not if you want)
