For Caleb's first meeting with Mistress Ebony, his aunty - the lush-breasted Mistress Diabolique, as she was known to her well-heeled clients, but Aunty Debbie to Caleb - made him shower an hour before her arrival.
As Mistress Ebony's daughter, the lovely 25-year-old black beauty, Tammy, said when she arrived earlier that bright, sunny Sunday morning, "Mum likes to make a grand entrance."
After he had towelled down, Aunt Debbie shaved him in his armpits, and then went around his body, removing any traces of bodily hair from around his nipples, his calves, thighs, his back and his belly.
Then she shaved his cock shaft and trimmed his pubic bush where it had sprouted slightly since his original shave on becoming a tyro slave for his 40-year-old aunt.
The naked, full-breasted dominatrix, then blow-dried the youth's longish hair, and brushed it until it fell in shining waves of lustrous jet-black almost to his well-muscled shoulders.
Finally, Aunty Debbie bent him over and inserted his now standard wear for "slave" occasions - the six inch black rubber anal intruder fitted with the sturdy strap which attached to a tight-fitting engorgement strap around the 18-year-old's cock and balls.
Standing up, Aunty Debbie looked approvingly as her nephew's thick-veined cock stood up in all its uncut glory, pre-cum already from it's unseeing eye already starting to drool in anticipation of pleasures to come. The pressure of the dildo and the engorgement strap had already pulled the lad's foreskin slightly down over his pink, glistening glans. Yes, thought, Aunt Debbie, you'll do, you'll do nicely.
The 40-year-old veteran of several years of female domination, then pulled on her black, PVC playsuit, which had strap arrangements from beneath her breasts to the hem line at her navel. The gleaming garment was such that her 34-inch DD boobs were bare, thrusting forward, and her minge was uncovered, as were her buttocks.
Aunt Debbie pulled on a pair of high-heeled PVC domina boots, which shone wickedly all the way to mid-thigh. Then she was ready, as was Tammy, who had chosen her traditional shiny black satin bra, suspender belt, gleaming black, seamed stockings and high heels. She spurned panties, revealing her thick-lipped labia.
A "Ding-dong" ring of the door bell announced the arrival of Mistress Ebony and Aunty Debbie kissed the eagerly hard-cocked youth on his cheek and whispered: "That's her now. Bring her into the lounge, and then she'll no doubt want you to perform some minor tasks before she starts work on you. And don't worry - she's a bloody brilliant domme, you'll love it!"
The lad grinned and walked swiftly to the door as the chimes of the door bell "Ding-donged" once more through the large house.
Debbie and Tammy settled down on a long, large leather couch, and from their positions they clearly heard the exchange between the 18-year-old lad and the 43-year-old black domina.
"Hello, Mistress Ebony," said the youth, "Mistress Dominique asks you to come into the lounge where she's waiting for you with Tammy."
"Lead the way, you stiff-pricked young devil, you," came a husky, deep but very feminine voice and soon the naked slave was standing quietly to one side as Mistress Ebony moved into the room and gave the now standing Mistress D a big hug.
"Darling," said the ebony domina, "thank-you so much for inviting me around to meet your new slave - and a nephew, too, you wicked woman!"
"I trust he's to your satisfaction," said Debbie, smiling as she looked at Tammy's mum's choice of clothing for her first visit with young Caleb. As Debbie had suspected, the older domina's selection was mouth-wateringly erotic.
On her statuesque tall body - she was just short of five 10 in her high-heeled boots - was a shiny, black plastic mac, with deep pockets and a high collar pulled up so it half-covered Mistress Ebony's long, black, lustrous straightened hair.
"Be a darling and unbuckle my belt and hang it over a chair," said the 43-year-old dominatrix. Debbie watched with interest as a trembling-fingered sex slave unbelted the mac allowing it to fall open. The lad's eyes widened as he saw the domina's full, firm body, thus revealed, but first he duly obliged the lady's instruction, and laid the garment over a chair.
He then turned and Debbie thought he might drool as his gaze took in the lush-breasted beauty's erotic outfit. Her 40-inch breasts - quite a bit bigger than her daughter's - were strapped into an open-slitted black leather brassiere, the nipples erect, the areolae wide and prominent around the stiff nubbins.
On her hips, Mistress Ebony was wearing a sort of g-string, a device of black straps and a black leather patch which covered her mons, but was bare at her crotch, revealing thick labia lips. On her feet, tie-front boots came to just below her knees.
Mistress Ebony smiled at the lad and crooked her finger: "Here, Caleb, come to me."
The teenager almost bounded into her arms in his excitement, and the dark-eyed beauty pressed a soft kiss on his mouth.
"Now," she said, sweetly, "my darlin' daughter tells me you prefer mature women. That you absolutely adore your lovely Aunt Debbie. That right?"
Caleb nodded eagerly, pressing his upper torso against the domina's lush breasts. "Yes, Mistress Ebony," he said, in a thrilled whisper.
"Well, let's deal with that, for starters," said Ebony. "I'm a domme, sure, but the Sabbath is my day of rest, so what say you call me 'Aunty Ebony'? How's that sound, you lovely young cockster, you?"
Debbie saw Caleb swallow deeply. "That sounds lovely, Aunty Ebony," he said, immediately revelling in his new domme's appellation.
"Right, glad that's settled," said Aunty Ebony, stroking the youth's flowing hair. "Now, you wanna play a game downstairs with your new aunty?"
Caleb again nodded, and Debbie thought typical Ebony - the lad was immediately and willingly totally under her thumb! Well, she reflected, that's what being a good domina means!
"There's a good boy," smiled Ebony, stroking the teenager's thick erection, "I love teaching my new boys my favourite game - by the way, Cal, you ever played 'Postman's Knock'? I don't mean the old party game, I mean the adult version?"
Debbie's hand strayed to her pussy - if there was one of Ebony's domination games that really excited her to witness with a new subby, it was "Postman's Knock - Mistress Ebony Version"!
"No, aunty, no, I haven't," said Caleb, in a voice thick with anticipation.
"Oh, you'll just love it," smiled Ebony. "Now, in my mac pockets you'll find a paddle - that's where the 'knock' part comes in - and three envelopes. That's the 'postman's' part. Bring 'em downstairs and I'll teach you your new sex slave game."
Caleb went to the raincoat he had carefully folded over an easy chair and from it produced three small white envelopes and a thickish leather flogging paddle, about eight inches long by three wide, with a hefty rubber-gripped handle.
Debbie knew from previous experiences of watching Ebony wield the implement that it could produce a deep red butt-marking, but never break the skin, such was the 43-year-old dominatrix's skill at applying the weapon of correction.
Down in the torture chamber, Debbie and Tammy both settled into large, leather easy chairs and spread their thighs wide. Each was fully aware of Mistress Ebony's version of "Postman's Knock" and each enjoyed stroking their pussies to pulsing completion during the 20 to 25 minutes it usually took to play the game.
Ebony, for her part, busied herself with fastening the naked sex slave to the padded flogging stool, arranging Caleb across it so that his anally-intruded backside and hanging balls were presented to the two dommes in the audience. Then she placed a small wooden stool in front of the larger leather one Caleb had been strapped to, and placed the three envelopes on it.
Stepping back she looked down at Caleb, who looked up at her haughty pose with a look of sheer dog-like devotion.
"Now, my darling," she said, in an extremely friendly tone, "we're going to play the game. I'm the postman, and I'll tell you, you have mail. The mail, of course, is these three envelopes. In each is a sheet of paper with a number, the numbers being 6, 12 and 18. All clear so far, sweetie?"
Caleb murmured "Yes, Aunty Ebony" and Debbie started to stroke her minge. She loved this part of the ritual, the gradual explaining to the slave as to how he was to be punished - she knew that the ritual was a vital element in domme-slave play!
"Now, you have to guess which number is in the envelope in front of you. Let's say, for the sake of argument, you think it's six. You will receive six strokes of my little paddle, and after that sixth stroke you will call out 'Open the envelope, please, aunty'," the lovely domina informed him.
