I watched as Riley pulled her stomach in, realizing that the moment of no return was approaching. What thoughts must be going through her head, I wondered as the belly of my fingers moved on so she could play with her short nipple. Then I moved my fingers down to her belly and the middle finger sat down to tease her navel, and I heard her exhale through her mouth. Slowly, with my fingers and hands, I worked my way down to her blond hairs, and I tugged lightly at them with my fingers and watched her hips rise accordingly.
I lifted my hand from her body, took her left hand in mine, and placed it on my erection. She pulled her away when I released her, but I brought her back to my cock and told her to hold me. Her hand did nothing, just rested lightly around my tough guy, but my fingers were back on her blonde again, gently ruffling the curly girl's hair. Her hand moved lower, gripping her entire pubic mound, and I felt her body shake under the touch. “My lovely stepsis, do you want me to stop or should I continue, is the decision for you?”
