Do this
Mistress is on the bed on her back and slowly and carefully walks slave object to the bed. Mistress lays on her back in the edge and with a leash tugs on the slave objects collar to instruct for each penetration.

If slave object doesn't penetrate on a tug mistress will paddle her ass. When mistress finally cums she will let slave object stand until she deems fit.

If slave object does well and mistress is satisfied then mistress will put a condom on cage and use vibrator to get slave object to cum into it. She will collect the cum and make the slave object eat it. For extra humiliation mistress will pour the remains on her stockinged feet and have maid eat it off there.
