"No, no, mercy, please, pretty please, don't let her do this to me," Theresa begged, as Aunty Caroline walked behind my pinioned body.
"Now, now, Theresa," said my aunt, "don't be so silly. Sam here has been at great pains to save her pee pee for you. It would be extremely churlish on your part to refuse to drink it down, wouldn't it, Sam?"
"Yes, it would, aunty," I replied, through gritted teeth when what I really wanted to do was bellow "For fuck's sake let me piddle!"
"So you, see, Theresa, Sam wants you to drink her glorious golden nectar. Now say 'sorry' and we can get on with it," said my teasing aunt.
"Sorry, Sam," said Theresa, in a tiny little voice, from her position just below my minge.
"Didn't hear you, Theresa," snapped Aunty Caroline. "Speak up and beg her for permission to drink her lovely champagne down."
A stifled sob came from the woman below me, then she spoke, far more clearly: "Please, Sam, please let me drink your golden piss, please piss down me, please, I want it!"
"There," said aunty, "that's much better. Now we can get started. Really, Theresa, such a lot of fuss!"
The next thing that happened was Aunty Caroline's lovely long fingernails making contact with my skin, tautened by my position in the flogging frame. They traced from my armpits down my rib cage, sending tingling little thrills through me. It was now, for the first time, that I realised I was extremely ticklish! Aunty's devious tracery continued over my belly, up to my breasts, then into my armpits again. Soon I was writhing and wriggling from her caresses and then, suddenly I felt a great relief in my bladder and I began to piss!
At first it was just a dribble, as if my system had shut down from the hours of denial and was reluctant to let go, but then with a relief that was massive, my release gushed into one long, steady stream.
Theresa beneath me was gulping and gasping and chugging me down for all she was worth until, after some 30 seconds of my flow, it became too much for her and she had to shut her mouth.
Streams of golden fluid flowed down both sides of her mouth onto her chin, down to her breasts, then further south. Aunty Caroline, kneeling beside her, watching intently, snapped: "That spillage will cost you, my darling little piss drinker!"
And Theresa's mouth opened again to receive the last 10 or so seconds of my bladder evacuation. At last I had finished, and I hung, limp and exhausted but infinitely more comfortable.
"Now thank her," snapped Aunty Caroline, and Theresa's response was not spoken.
Her tongue flickered out and traced its way across my piss flaps, down to my cunt, then up to my clitoris. Soon I was wriggling on her face, and then my relief became even more luxurious as my orgasm flooded through my groin and I exploded with delight on the 45-year-old woman's working mouth.
Aunty Caroline then freed Theresa and the two women both unstrapped me from the frame.
"Now, Theresa," said my aunt, "I'm not one who believes in dragging out a slave's suffering. I promised you a punishment for that disgusting spillage just now and Sam will inflict it right now."
Aunty Caroline then took a red rubber bit and bridle from her equipment table and placed the rubber in Theresa's mouth. She then made the woman go down on all fours.
Then she addressed me: "Time for a little ride, darling Sam. Use the crop on her arse and get her to complete a few circuits around the room, then steer her up to my pussy - I've got a little gift for her, as well."
Aunty walked over to a comfortable easy chair, slung both her boot-covered legs over its arms and began to stroke herself, as I climbed aboard the broad back of the naked slave.
I grabbed both ends of the reins together in my right hand, and wielding the riding crop in my left whacked her across her buttocks and spat out about the only equestrian phrase I knew apart from "giddy-up".
"Walk on," I said as the crop made contact with her arse, and the 45-year-old began to make her way in a large circle around the torture chamber, me with my high heels just up from the carpet so she had to work under the full burden of my weight. As we wound our way around, Aunty Caroline was working slowly on her minge, several fingers sometimes disappearing up her lovely gash.
After three circuits, Aunty Caroline called out in a husky voice: "I'm ready for her now, Sam, next time bring her up to my pussy, please."
I flogged the slave several times just for the hell of it during the final lap, then brought the panting woman up to aunty's chair. The aroma of aroused sex flesh was apparent even from where I sat on the slave's back!
I pulled the bit from Theresa's mouth and went to dismount but was dissuaded by my aunt.
"Stay there, Sam," she ordered, "and you can take for another few laps after she's had her refreshment."
I remained seated on the panting woman's back, then watched as aunty slid her buttocks down the seat until her snatch was inches from Theresa's mouth.
"Horsey worsey want drinkies?" Aunty Caroline said, in a girlish, sing-songy voice, which forced me to choke back a peal of laughter.
"Yes, please, Caroline," said Theresa, all pretence of disliking the habit now vanished.
"Open up, then, darling," said aunty, and I watched with fascination as a thick stream of golden amber fluid jetted from aunty's piss slit into Theresa's wide open mouth. It was strong, but nowhere near as long as mine and after some 20 seconds, Theresa was forced to placed her mouth against aunty's minge to lap up the remaining dribbles of piss.
"Lovely," said Aunt Caroline, after her piss, "now you may thank me, darling."
And once more the 45-year-old was forced to perform at a moist, demanding pussy until aunty's cries of ecstasy indicated her climax.
The I resumed riding the lush-breasted, naked slave around the torture chamber, before being ordered to dismount by my aunt, who then placed Theresa, now minus the bathing cap, back into the flogging frame.
"See if she's ready to come, darling," said aunty, shoving a stool in front of Theresa's pussy.
I sat on it and tasted the mature sex slave's wet quim, running my tongue from anus to clit, with several stops in between, and enjoying the lovely taste of sex mingle with the aroma of my piss, from Theresa's spillage.
The 45-year-old soon writhing and bouncing on my mouth, but when it seemed she was about to relish a climax at last, Aunty Caroline indicated to me to stand up.
"Of fucking hell, fucking, fucking hell, you can't do this again, please, Caro, please, this is unbearable," she pleaded.
Aunty then handed me a long flogger with a large, square flap on its end and told me: "You work on her shoulder blades and buttocks. I'm going to finish her off, it's time she had her orgasm!"
I stepped behind the lovely back and buttocks of the magazine publisher and started to work over her shoulder blade region, then her buttocks. The flogger made a delightful "Thwock" noise each time it came into contact with her fevered flesh.
