On the morning that Theresa was due to visit my Aunty Caroline's for a session of female domination, aunty told me: "We need to get you kitted out. Let's see what we can come up with from my collection."
And we stepped, both of us naked, into her walk-in wardrobe, which had been the catalyst for my introduction into sex with an older woman and her skills at femdom.
"Theresa is a fussy submissive," my 38-year-old aunt informed me. "She insists on me wearing really erotic outfits, and since she's calling the shots - well, for the couple of hours she's here, anyway - I go along with that.
"And of course, femdom in really nice outfits is all part of the fun. Now, what can we organise for you?"
Aunty riffled among her wide collection of gear, then pulled out a bra which she held out for me to try on. It was a black, open-fronted PVC job, which pushed my 34-inch breasts into what I thought was superb uplift.
"Good," said Aunty Caroline, "Theresa is into body worship and your breasts must always be available. That looks good. Comfy?"
I nodded, looking admiringly into the mirror set on one door of the walk-in wardrobe. "Even I fancy myself," I told Caroline.
Next Aunty Caroline tossed me a black leather garter belt. "Let's see how this looks."
I tried it on. It was quite a broad belt and gleamed across my hips. I thought it looked sexy. "Stockings from this package," said aunty, handing me some shiny, black seamed stockings.
I smoothed them over my legs and turned to look at my rear in the mirror. They looked sensational!
"Panties?" I asked Aunty Caroline.
"No," she said, with a firm shake of her head. "During a femdom session your breasts may be available for body worship, but your pussy must always be open for business."
"Speaking of pussy, aunty," I said, "I'm really starting to get eager for a piss, I only had my early morning piddle when I got up and you've been pouring the coffee into me."
"Sorry, darling," said Aunty Caroline, "but Theresa is a big fan of piss punishment and I want you to be able to give her a really good drenching. Please try to hold on."
I nodded. "OK, aunty, but it's going to be difficult."
"I know, pet," smiled my aunty, "and I'll try to get around to the water sports part of it quickly, but the longer you hold out, the more effective it will be for Theresa. Promise me, she'll thank you for it."
I then selected a ridiculously high pair of black patent leather platform shoes, and presented myself to aunty for inspection.
"Perfect," she smiled, "if I wasn't into domination I'd go down on my knees before you myself, you lovely young minx. Now, a couple of tips. Unlike many submissives, Theresa is not into verbal abuse. Calling her a slut, or a bitch, or a fucking pervert, is not going to get her bells rung.
"She calls me Caroline, I call her darling, or Theresa. But that's not to mean there's not a lot of verbal teasing going on, do you understand?"
I nodded, not really sure that I did, but hoping I'd pick it up as we went along.
"Right," said Aunty Caroline, "she's due in about half an hour. When she arrives, you pop down into the chamber and when I bring her in, I want you standing in the middle of the room, between those posts, hands on hips in a really aggressive-looking manner.
"I will bring her up to you and introduce you. Her first contact with you will be a short performance of cunnilingus."
I nodded, excited at the thought that the very first bodily contact I would have with a woman who would be a total stranger to me was going to be her mouth on my minge!
"And after that, the performance will unfold according to my directions. Just follow my lead and remember that Theresa is a devout submissive, she's really into it," said Aunty Caroline.
"Now, lay down on your bed, take some deep breaths and try to control that bladder of yours!"
I did as instructed and at about 10 to 2, Aunty Caroline entered my bedroom and told me to get down into the chamber. "She's due any minute," she said.
Heart thumping from excitement, bladder thumping through the pressure of needing to pee - not excruciating, but quite painful - I made my way down to the torture chamber, and according to aunty's instructions stood centre-room and waited hands on hips, trying to look as stern and strict as possible.
Then the door swung open, and there was Aunty Caroline, in a black quarter-cup bra similar to mine, those lovely long black leather boots and a shiny black leather belt which circled her hips.
On one hip a holster held a short, single-thonged whip, which dangled half-way down her thigh. She looked superb!
