It was getting late as she walked to the window and opened it. She leaned over and was halfway out as she yelled for her brother. As she stood bent out the window she looked around as the window fell. She let out a startled yelp as it trapped her half in the house and half outside. She wiggled around as she realized she was stuck.
Her brother walked in and looked as her tight shorts showed her nice round eighteen year ass off nicely. It bounced and wiggled as he smiled at it. Denise didn't realize he was in the door way watching her with a growing dick. He felt himself grow rock hard thinking about how tight his sister pussy was. He reached down his pants and began jerking it as he watched her ass move. Then he realized, it was just them home, their parents were in town for a couple hours. He grinned as he had an idea that had been in his head since he met her.
He walked behind her and looked down at her tight jean shorts as they moved around. Denise stopped and looked around as she felt a hand grab her ass. She tried to see who it was but the hand slide down and between her legs. He began massaging and rubbing her on the outside of her shorts as she looked around with wide eyes.
Denise felt herself growing moist from the rubbing as she felt two fingers slip into her pussy. Her eyes closed as she bit her lip. He smiled as he fingered her tight, wet hole. He slid a third finger in as she let out a moan. Denise smiled as she felt herself get off as the fingers picked up the pace making her cum flow.
He looked down as her cum dripped to the floor. He pulled his fingers out and sniffed his sticky fingers. Denise hung her head as she panted. She felt her shorts unbutton and get pulled down exposing her pink thong. He smiled as the cum soaked thong was pushed aside showing her pretty shaved twat.
