James selected an electric control unit and fastened the clips on the leads to Aron's balls. Then an electric buttplug with the other terminal to a sound which he pushed not too gently into Arons pisslit.
Then he started playing with the controls. Alternating between the two circuits, or both at the same time.
Strong current, low - nearly nice stimulation level - and then strong again.
Aron screamed. Struggled desperately with the bondage, but to no effect.
James was rock hard. The screaming tormented boy, the control he had over him, and the knowledge that he could do exactly what he wanted to him made him horny. And the more horny, the more sadistic he became.
