Michael prepared himself as he had been instructed for the day, Domina had arranged that Mistress Katie would be supervising him while Domina took care of other matters. He had been eagerly anticipating the awaited date; it had been many months since he had submitted to Mistress Katie. Domina's friend Katie had visited to supervise his state of chastity and frustration during each of the past four summers, ensuring Michael remained in an appropriately slutty state, needing to cum and needing to kneel before a demanding lady, while Domina was away for weeks at a time.
Sadly, Domina's schedule did not leave her the time or energy to supervise her slut boy as often as either of them might wish. So it was to the benefit of all that Mistress Katie was willing and available to take him out of Domina's way for the day and to ensure he received some of the treatment he so deeply desired, and needed to ensure continuing good behaviour.
Michael showered and shaved, both face and balls, locked the chastity cage on his cock with a condom over the tube to catch any messy drippings, and dressed in the shorts and shirt Domina had chosen for him. As he reached the bottom of the stairs she was waiting for him. Dressed in a long black skirt, polished five-inch black heels and a white blouse, Domina looked like a school mistress ready to discipline a naughty pupil. She held out her hand.
"Keys," she said.
Michael placed the two small brass keys in her hand, one loose, the other on a long leather cord. He watched as Domina slid the leather thong over her head, letting the key fall between her beautiful breasts. The other she placed in a small envelope. Sealing and signing it to prevent tampering she handed the envelope back to Michael.
"Give this to Mistress Katie when she picks you up."
"Yes ma'am," Michael replied softly.
Domina then took her slut's face in her hands, her deep red manicured nails framing his face as she lowered her own to kiss him deeply. Michael's mouth parted as her tongue slid deep between his lips, gently fucking his face as his Domina kissed him. She broke the kiss as he started to moan around her thrusting tongue and stepped back, her lipstick bright on his lips.
"Nice colour," Domina said with a smirk, "I want you to behave yourself for Mistress Katie today, and I will see you later."
"Yes ma'am," Michael whispered, "I will be good."
She retouched her lipstick, and Michael then watched as Domina headed for the door, her own schedule pressing.
His own lips now cleaned, Michael waited patiently for Mistress Katie. His mind worked overtime as he reviewed her past visits. He knew she enjoyed keeping him horny and dripping inside his cock cage for hours before she considered releasing him. Those releases, when they did occur, were intense and draining, but that act of release did not free him from his commitment to serve his Mistress. Each time, as his arousal ebbed in post orgasm, he was still expected to consume his collected pre-cum drippings, and his cum if Mistress had taken his orgasm, by whatever method she decided to feed it to him. Michael could feel his cock trying to rise against the confining cage as he recalled sucking his cum from Mistress Katie's fingers, and from her manicured toes, but the narrow tube of the CB-6000 had been effective in training his cock not to fight its sturdy confines.
As he contemplated switching his computer on while he waited, Michael heard Mistress Katie's car pull into the driveway. Nervous with anticipation, as he always was when she visited, he opened the door as she reached the step, and closed it behind her as she walked into the house.
Mistress Katie walked down the short hallway into the living area, she turned to look back towards the door where Michael had remained. She wore a translucent white blouse covered by a short black satin vest. When she turned, Michael could see the exposed lace of her bra through the open neckline. Mistress Katie's legs were covered by a knee-length leather skirt. Cut wide, it opened and flowed around her shapely legs as she walked. The patterned black hose she wore was evident on her sexy calves down to the black stilettos she wore, the toecaps of each shoe covered with pointed steel studs.
"Well, slut," Katie said in a calm voice as her toe tapped on the wood floor, "is that how you have been trained to greet me."
"No Mistress, I am sorry Mistress," Michael blurted.
He moved quickly down the hallway to the open area where Mistress Katie stood. Under her watching eye, he pulled his shirt over his head, then lowered his shorts and boxer-briefs to the floor. Stepping out of his clothes he stood there, naked except for his cage, his hands at his sides, exactly as he had greeted Mistress Katie for each of her previous supervision sessions.
"That's better," she said, "just because I said we were taking a road trip today doesn't excuse you from your other responsibilities."
"My apologies Mistress," came the whispered reply.
Silently, Katie started to inspect her slut. Her hands slid across his shoulder and chest, Beautifully manicured fingernails in red with black tips closed on his sensitive nipples, teasing and pinching. Michael moaned at her touch, and struggle to remain still as he stood for his Mistress' inspection. Standing close, she again slid the tips of her nails over Michael's hard nipples, scraping her nails gently over them again and again as he trembled under her touch.
"You like that, don't you slut?"
"Yes ma'am," Michael groaned weakly in reply.
Mistress Katie's hands slid over Michael's chest and back, stroked his ass as she imagined spanking and fucking him, and tested the security of the cage that encased his cock. Michael moaned softly as her fingernails slid across his ass. He trembled when Mistress Katie took his balls between her thumb and fingertips of each hand. She rolled and squeezed them gently, then squeezed again, a little more firmly, watching Michael's face for his reactions. She smiled as he moaned at her ministrations.
"Well, these feel nice and full, how long has it been since they were drained?"
"Weeks, Mistress," he moaned.
"Good," she smiled, "then they should be nice and full for me. But we're going to see how much more there's going to be by the time we unlock this cage. Speaking of which, you have something for me."
"Yes Mistress, the envelope is in the pocket of my shorts."
"Well, put them back on, and hand it to me. Leave the boxers there, you won't need them. Quickly now, we have to get going."
Michael redressed as Mistress Katie headed toward the door. She stood there with her hand out for the envelope, and after Michael presented it to her, she indicated that he should open the door. By the time Michael had exited the house and locked the door, Mistress Katie was already in her car waiting for him. As soon as he had buckled his seatbelt, Katie reached over and tugged on the belt holding his shorts closed.
"Open them," she ordered.
Michael undid the belt and, after looking around to see if any of the neighbours might be watching, unbuttoned his shorts and slid the zipper to the bottom.
