The story begins here

The door swings open silently, and this time there are no slaves awaiting us. Alone in the centre of the room is a black leather spanking bench. It has a padded rectangular top that the spankee straddles, with parallel lower supports for them to kneel on. I don't seem to be alone in remembering the bench from previous sessions with Goddess, and it occurs to me that we may all have sweated and cried on that exact piece of furniture.

V squirms, the feeling of her hands being restrained always has that effect.

At the far end of the bench is a new addition, a metal locking mechanism that appears to restrain the occupant when something is slid into a slot.

I smirk at V as I realise what's meant to fit inside the slot, and she follows my gaze.

"Fuckkkkk," she moans, "This dress is too tight for getting on that bench."

Julia steps up immediately, "I can help with that" and begins to unzip V, peeling her dress over her shoulders and kissing each piece of skin as it's exposed. I watch V squirm, and the tension in her hands as she subconsciously tests the restraint.

V has to lower her hands as she wriggles out of her clothes, with Julia helping her step out as James supports her. Soon she's back in just the black lace body I watched her slip into a couple of hours ago, with her dress slightly awkwardly dangling from her wrists.

Julia takes advantage of her exposure to grab a handful of V's pale, freckled arse, and V gasps as our new friend's fingernails dig deep into the soft flesh. I grin at James, and indicate with my eyes he should do the same. We might be here to solve puzzles, but that doesn't mean we can't enjoy each other in the meantime.

V makes eye contact with me as the two of them run their hands over her body. She knows that I know she's loving every second of being vulnerable like this, and that Goddess set this up just for her.

As much as we're all enjoying this, I'm suddenly aware that the clock is ticking. I beckon them towards the bench, and V is helped onto the pads by them both. She slides forward with her wrists outstretched, and I come close to kiss her deeply as she engages the thumb trap into its slot.

As the mechanism engages something opens beneath the bench and drops several pieces of wood with a clatter. We gather them up between us, six in total, and inspect them closely.

Each one is shaped like part of a square spanking paddle with a handle, but with pieces missing and with odd looping carvings that look like parts of numbers.

James takes one from Julia, and fits them together, sliding and interlocking two pieces until the form a smooth-sided square spanking paddle about 10cm on each side. The carvings still don't make much sense, seemingly fragmented and broken.

I fit my two together in a similar way, and Julia follows suit. Then we look at each other and realise we're each holding a spanking paddle with some sort of message on them, and in front of us is the blank canvas of V's arse, exposed and inviting.

V moans, as the realisation hits her too. Then she arches her back and squirms, seemingly mentally preparing herself for the coming pain.

I hold my paddle out, with the carvings facing up, and James and Julia follow suit. Parts of the pattern seem to make letters, but it's too intricate to make full sense of. The patterns on each paddle seem to come together to make a message, but they will need to be oriented carefully to line up.

I suggest we get started, and line up to take a careful aim at V's left cheek. The first two smacks with the paddle gain a moan and a whimper from V and leave a pale pink glow, but no clear pattern emerges.

"Harder", V says with conviction, "spank me harder."

I grin and go again, this time five, six hard spanks with the wooden implement, each carefully aligned. A pattern starts to appear, and I give her five more hard smacks.

"My turn!" calls Julia excitedly, and takes position opposite to align the pattern on the paddle with mine.

Julia is stronger than she first looked, and gives ten hard smacks without a break. More of the lines appear on V's cheek, surrounded by a painful glow of deep pink.

Julia stops to trace her fingers over the signs of impact, then slides her hand down between V's cheeks and underneath the side of her lingerie. I watch V twitch and squirm again as Julia explores her, and know just how wet she's likely to be.

Julia pulls her fingers away, walks around to squat nose to nose with V and sucks her fingers clean. Then Julia leans forward for a deep, passionate and moany kiss as the two of them share V's arousal.

James's turn next, and he kneels down to align his paddle vertically. Julia stays cradling V's face as each hard smack lines up in the same spot, and I see V's eyes start to fill with tears as the relentless pounding of the same exact spot on her arse takes the force of every blow.

After ten decent blows, James steps back, and immediately looks confused. The pattern is a mess, a jumble of nonsense now. He looks at his paddle, and claps his hand to his face.

"Fuck, I'm sorry V, I had it the wrong way up. I think we need to start again…"

I come closer, and it's clear he's right. The pattern is ruined, making no sense now.

James climbs up to straddle V now, facing her arse as he starts afresh on her right cheek this time. Ten quick, sharp blows form the beginning of recognisable forms.

Julia next, matching the pattern from V's right side, and the pinkness starts to glow, almost matching the other cheek.

Then it's my turn, and I go hard from the beginning. V sobs, but stoically doesn't move a muscle as the blows jiggle and bounce her arse.

Then I step back, and there is the pattern. Surrounded by loops and intricate curls, four numbers in a loopy, curvy font are white and distinct in the centre of V's glowing pink arse cheek.

Inspired, I follow Julia's example, pulling aside V's lingerie and pushing my finger into her soaking wet pussy. She feels hot and tight and needy, and I take a moment to enjoy the sensation of her body. Then I slide my glistening finger out of her pussy and use her juices to trace the numbers on her skin

4 2 6 9

We look around the room for somewhere to use the code, then I find a keypad below V's restrained hands. I enter the digits and a key drops from below and there's a click from the trap, and she pulls her thumbs out to rub them back to life. She holds up her dress, briefly considers putting it back on, then clearly decides against it.

She reaches back gingerly, and winces slightly as she feels the heat and tenderness in her cheeks. She gives James a playfully stern look that I know means she'll get her own back with the mistake about the alignment.

Then V grabs Julia's hand, and struts off towards the next door with her dress in her other hand and her pink arse glowing. She inserts the key, turns it, and together the two of them push on the heavy double doors.
