Control. That’s what most of it all is about. You feeling in control. He feeling loss of control.
A simple thing to do, to assert control: Tie him to your bed (with his cage still on)… tease him, touch his body, make him strain against his cage, see how blue his balls become.
Then… sensually unlock him, and take the front of the case off.
Tease him with your hand, your mouth, your breasts, your whole body. See how hard he becomes.
Then, have him calm down, and put him back in his cage.
Only then untie him.
This… is control!
