Obedience makes you hard.

Be prepared to open up your mind for me, to be able to take your free will, and have power over you.
This will enable me, or your partner, to take great control of you in the desired sexual ways.
You will love the power and control that you will obey to.
Obedience makes you hard.
The more you obey orders, the harder you will become.
