A noise disturbs her

Closer and closer her fingers inched down to her clit. Her nipple pinching hand had turned into a steady grope of her breast and her breath was staggered. The visual fantasy of the invading hands from earlier had reached her zipper of her shorts and as the sound of her zipper echoed in her mind, a sound from outside of the shower had alerted her and she jumped as her visual fantasy revealed the true outcome from earlier as she was greeted by the obscured face of her brother behind her, he had fallen back at her sudden realization it was him. The image of him lying on the ground, legs open, shorts and boxers at his knees with his cock wobbling burned into her mind again. She snapped out of her daze felt the mixture of disgust and arousal in her stomach. Another noise was heard and she looked towards the shower curtain. She jerked her hand out of her bush realizing she was still diving down and reach up to shower curtain and drew it back slowly.
