You dont slide your finger in and out like you would in your pussy but it does move around inside me. I am just clinging onto your head now as it bobs...frantically in fornt of me. I know Im going to cum soon if you carry on and I warn you that if you dont stop Im going to cum in your mouth or all over your face.

Our built in AI could cut off the current to any part of our skeleton and reshape it any way we wanted before reapplying the current and making the bones rigid.
