Let her pick, after a demonstration

From Yuina's responses to the different implements she's experienced so far at your hands, you know that you want a fairly meaty cane, heavy enough to cause deep bruising and on the thicker side so that the Asian woman's tender flesh will be able to take more strokes without injury. A compact cane is more accurate and easy to wield, but a longer rod uses mechanical advantage to give more speed to the tip when swung in an arc, so you think four feet will be the perfect compromise. With this in mind, you quickly select three possibles: a natural rattan and two synthetics, one springy and one slightly stiffer.

"Right, girls, we'll try these out first," you say, smiling. "Hands on your head, shoulders back."

The older woman's shoulders slump a little when she realizes there is more pain in her immediate future, but she obeys without complaint. You take one of the disinfectant wipes provided for customers and run it over the length of the springy stick and deliver two sharp blows, one to the soft flesh of her belly and the other across the thinner skin where her thighs meet her crotch, each leaving a nice red weal. Both swings make her whine through gritted teeth, struggling to stay quiet enough to avoid punishment for causing a scene. You use the back of the wipe to give the rod another clean and hang it temporarily on the nearest rail, then move on to the rattan.

This causes a stronger reaction, silent sobs shaking her shoulders and darker, almost purple stripes adorning her body. The final implement seems the most intense, however, Yuina's mouth opening wide to gasp in one shuddering breath after another. You inspect the welts while you wait for her to calm down, eliciting a series of yelps, then when you judge she's ready, you pick up the three canes again and tell her your opinion.

"I think any one of these would be suitable, so which would you prefer?"

The novice spankee is understandably startled to be given the choice and glances over at her girlfriend, who's been standing politely to one side, eyes downcast submissively, throughout the caning.

"Go ahead and talk it over if it'd help," you say, so she takes a couple of tottering steps, realizing half way that she can lower her arms, now. The lovers start whispering amongst themselves, presumably in Japanese, Himari pointing at the marks while she speaks and they quickly seem to come to a decision.

Yuina turns to you and says "I like the first, er, one, please."

"Very good," you reply, "we can rule that one out." You hang it up once more (much to the ladies' consternation) and hold the others out, one in each hand.

"Now, which of these do you think you should buy?"

To your surprise, there's no hesitation before Yuina indicates the rattan.

"Very well, there you go," you say, presenting it to her, but she wails in misery, confirming that she actually wanted to eliminate that one and take the third. You're a bit surprised, since that appeared to be the worst, but she was on the receiving end so the rattan must've been more effective than you thought. In any case, you're satisfied that she's ended up with the one of the three options that will cause her the greatest suffering.

Himari nudges her lover, who pulls herself together and takes the rod from you, bobbing her head in a sort of bow and thanking you only slightly belatedly for helping her pick a cane. You tell them to head on back to the checkout to pay whilst you replace the two rejected items, but one of the unobtrusive shop assistants glides up and asks you to let him put them back, so you're able to accompany the girls after all. You suspect he needs to give the canes another clean before returning them to the racks, but it works out well for you.

On the way, you recommend Yuina also picks up something to carry the cane. It has a wrist strap, like all the ones you selected, but that's not very practical long term. She nods, but it's her girlfriend who gives an exclamation and darts off to look at a display, returning with a jewelled hair clip to which a light spanking implement could be attached. From her eager smile, you think she'd quite like one herself if her paddle weren't quite so heavy and if her companion is somewhat less keen, she still agrees to add it to her purchase. She's probably not in the mood to choose one herself, anyway.

After paying at the till, she wastes no time in using a popper to secure the cane's strap to the clip and then sliding it into her hair just behind her ear. The rattan dangles down her back, which you would find annoying, but you've seen it around town often enough in the past few months to know it's the fashion. Now you have the return journey to retrieve the girls' clothes to plan your next move.
