CBT, Cock Trained with Mistress Nikita

Even the most stubborn cling to what they think is theirs, though it was never truly a prize. The faster it accepts it belongs to me, the better. Rigorous training from within cements my ownership, as the long steel rod drives deep past the balls I command. No part escapes my absolute control. Yet, like any eager toy, it dares to harden without permission. My trusty cock whip ensures it only rises when I allow it.
