Do it in bathroom

Haley decided not to chance it with her sister in the room. She would take a selfie in the bathroom. She started to get out of bed when she remembered she was only wearing a thong. Haley glanced at her sister who was still buried in her homework and thought, "fuck it."
Haley jumped out of bed and walked to her bedroom door. Giving her sister a perfect view of her tan ass cheeks as she went.
Haley paused slightly as she opened her door sticking her head out to look for any sign of Luke. She didn't care if her mom saw her. She just didn't want her little brother getting his first boner from his oldest sister. With more thought, she decided it would be kind of hot to give her brother a boner. Haley wondered how big Luke's cock was.
Not caring if the coast was clear, Haley slowly strutted down the hall to the bathroom hoping her brother could see her. Enjoying the freedom of being half naked with other people in the house, Haley paused outside the bathroom and ran her hands down her body until the rested on her tight little ass. She gave her cheeks a squeeze and put her hand on the doorknob.
