Use her hand for good

Steph showed no signs of waking up. She seemed fast asleep with her arm still extended in the air. I knew what I had to do. I slowly removed my gym shorts to reveal my erect member. I rose off of my knees and stood before my defenseless and exposed little sister.

I carefully lowered the doll's arm towards my penis, until Steph's hand came in contact. I squeezed the doll's hand, and Steph's body obeyed. Her hand gently gripped my penis, and I began to pump the doll's little arm. My sister, who lay naked and asleep beside me, was now giving me a pleasant handjob. I was in absolute bliss, knowing that her body was a slave to my will.
