There was a note and a small box on his desk when he arrived home. The note said "A gift for you, do not open until I arrive home" Mistress Victoria. As was Her wishes he sat naked except for his collar, ready for anything Mistress wished. Shortly after She arrived and entered the den, carrying a bottle of lube and a small towel.
She grinned and said "I see you saw My gift and like a good slut you did not touch it until I arrived."
She knelt in front of him and poured some of the lube into her hand, She rubbed the lube over his cock and balls and massaged it in. He squirmed and started to get hard. She chuckled and tossed the towel, soaked with cold water in his lap. He immediately lost the hardness. Opening the box Mistress Victoria removed a small steel ring with a post and fit it around his balls and slid his cock through it.
"I checked your computer and saw the porn sites you have been visiting. You are such a whore you can't keep your hands off of My cock."
She then pulled out a small steel cage and slid it over his cock fitting the ring on cage to the post. He knew She was right and tried to form the words to protest but could not. Lastly She removed a small heart shape lock from the box and clicked it into place.
"The heart shows that I love you but this is Mine and Mine only to touch and use, when I chose," She said.
With that She gave the cage several good tugs and was satisfied he would not be able to remove it. She took the key which was on a chain and put it around Her neck so it hung between Her breasts.
"The lock shows that though I love you I cannot trust you to keeps your hands off of what you no longer own nor have permission to use."
For the next few days he was very attentive to all of Her needs. Nightly he massaged her, showered her neck and breasts with kisses and nipples with tweaks with his fingers and then knelt between her legs burying his face in her pussy while he worked her clit with her favorite vibrator. Each time he could feel himself getting hard, the cage biting into his cock. Mistress Victoria moaned, screamed and teased his balls with her finger, slapping his ass with a paddle until she was exhausted and his face was dripping with her juices, the key between her breasts taunting him.
This went on for the full week, on the 7th day Mistress Victoria said "I have a treat for you. Go lie in the bed and wait."
