Get a shower
From Create Your Own Story
You walk to your closet and grab your towel. Since your bedroom shares a bathroom with your sister Jasmine's bedroom you listen to see if there is anyone in there.
Typically your little sister has music playing, water running, hair dryer blowing, etc. Always making noise.
After a second of no noise you decide to open the door.
You walk through the door and....
"Shit" you hear your sister say. "Fucking knock would ya!"
She was standing in front of the mirror with only a thong on when you first noticed her before she screamed. She must have been just standing there doing nothing, as her phone was on the counter and she was about 2 feet away from the mirror. You later think she was doing what you do in front of the mirror, self admiration.
Your standing there in the same place you have been since you entered. She turned to you as she yelled and, before covering up with her arms, gave you a full view of her tits. They are big enough that they bounced as she twisted and jumped.
Your mouth didn't physically open but you felt like your jaw hit the floor as you saw that your younger sister's tits with their small button sized nipples accompany her toned stomach and her ass that looked to be a bit less than a handful. Her hair was down, which reached to her mid back, and was, what looked to be, still a bit damp.
