"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."
