All of them

The suffering blonde lying on your sofa struggles to speak, her voice failing her while she weeps pitifully, but you forgive her the delay when she finally forces out the words pleading for all six of the remaining bumps to be applied to her most sensitive and intimate place. No sooner has she said this than she begins to sob uncontrollably and you wonder whether she can quite believe what she's asked for. You have no doubt she did it solely for your enjoyment and such awful torment is the last thing she really wants, which in itself guarantees you'll enjoy it all the more. You tell her to turn over and put her legs behind her head, then help her to do so, since she's so weak from the earlier part of her birthday spanking, then stand behind her bum and line up the bundle of switches with her quivering quim while she wails in quiet despair.

The supple rods splay out to cover almost the whole of her outer lips with a sheath of agony and Léa screams and screams, but so weakly it doesn't even hurt your ears, let alone cause you to worry about your neighbours. You revel in the scene and don't mind the delay at all, but eventually she manages to thank you and ask for the next, which you place slightly lower, the centre of the switches landing on the ever so sensitive flesh between slit and anus, but bending to scourge her all the way from the mound of her sex to the inviting cleft between slightly parted nether cheeks. You look into her glistening eyes to better appreciate her anguish whilst she gathers the strength to beg for the next lash, which you lay on in almost exactly the same spot.

Léa's body trembles and she squeals, tears soaking the cushion beneath her head. You check her ravaged skin, producing even more animated shrieks, then decide it's too delicate to survive three more strokes intact.

"Spread your labia for me, will you, Léa?" You ask conversationally, as though requesting nothing more onerous than passing the salt at dinner, but your guest's wails show the level of suffering she expects it to cause her. "Pull your clit hood back, as well," you add, cruelly. She obeys, gazing pleadingly into your eyes, her hands shaking with stress.

You intend to make the last three count and hit with merciless ****, striping her inner lips and the nub of her sex with livid weals. She falls silent, the pain shocking even after what she's experienced so far, then lets out a keening wail that dissolves into helpless whimpers.

"Oh, Jaques, thank-you for the lash," she sobs. "P-please may I be permitted to receive the twenty-fifth bump."

"Inner lips apart now," you reply and are rewarded with a view of your colleague's **** innermost core.

The wet squelch of switches scouring exposed flesh is drowned out by agonized howl, all self control lost as Léa convulses in exquisite misery. Then, after she pleads for one final, surely unbearable blow, you flick the tips of the rods over her swollen clitoris, the fingers holding back her hood also paying the price, although you think she scarcely noticed.

You kneel beside the sofa and take the blonde beauty into your arms, delighting as she clings to you in anguish whilst sobbing her gratitude. You can feel the ridges covering her sensual figure and know the close contact can only be adding to her torment, rather than assuaging it, but still she seems unable or unwilling to release you for long moments, while you soothe her with murmured words and platitudes such as well done and good girl, at the same time massaging the back of her neck and placing kisses on her forehead and into her tightly bound hair. Eventually, her clinch loosens and she seems to calm; ****, shuddering pangs replaced by steady weeping. She looks at you and pleads earnestly to be allowed to reward you for her breathtakingly brutal belated birthday spanking.
