Jakes eyes went wide, getting caught off guard by his sister. Holy shit she was hot He could feel his face flush red. It was a cute contrast to the rest of his light skinned body. He also felt a stirring below, his cock growing erect very quickly at the sight of his hot, nude sister.

His cock was showing no signs of retracting, all six inches of him pointing toward the wall he faced.
