Swap tasks, but they perform poorly

When you order the two tourists to exchange rôles, Yuina initially seems perturbed by the size of your manhood. You presume that she has seen penises before, but given her sexual orientation, perhaps not from such close quarters. Everything does look bigger the nearer you are to it, after all. She opens her mouth as wide as she can whilst covering her teeth with her lips, plainly scared of what you'd do if she were to scrape you, easily accommodating the head of your cock and trying to emulate her girlfriend by swallowing it. Unfortunately, but not surprisingly, she immediately encounters difficulties. Unlike her companion, she's not had to give any sex tips since arriving in the country and the lack of experience shows. Even with your hands firmly on the back of her head, she's unable to overcome her powerful gag reflex. More seriously, she's making no effort to stimulate you with her tongue.

That's not the only tongue action you're missing. The other half of the pretty duo is being unacceptably tentative with her rim job, even though she's only following in her mistress's wake. You exhort her to make love to your bum hole as though it belonged to her paramour, whilst forcing the tip of your dick hard against the back of the elder girl's throat. Himari at least makes an attempt to comply, but at that moment, her lover's gullet rebels and she uses her hands to push away, retching uncontrollably. Whether it's the unpleasant sound or the taste of your sweaty arse crack, you'll never be sure, but she also stops abruptly, one hand clutched to her mouth, fighting the urge to puke.

Both girls are looking pale, faces shining with perspiration and tears glistening in the corners of their eyes. You're about to order them back to work, when Yuina manages to pull herself together enough to apologise.

"Sorry, er, sir," she blurts out between heaves. "Please punish, er, us."

You tut loudly, shaking your head at her temerity.

"It's not for you to decide when you ought to be punished," you explain. "Asking a man to go to the trouble of spanking you is selfish and rude and just as bad as asking not to be punished. Get on your back, with your legs over your head."

You pick up her cane to administer six rapid stripes to her bum, not intending to give her time to count. Her cheeks are already showing the signs of earlier chastisement, but you think they can survive a sixer.

Yuina half screams at the first, before stifling herself for the remainder, howling into her fist, legs shaking with the effort of staying in position, but the flogging's over almost as soon as it began, although it takes her a few moments to realize it. She sniffs and blinks away her tears with a whimper, her girlfriend kneeling still as a statue behind you, trying to avoid attracting your attention.

"Thank, er, you for punish, er…" she pauses to work out why she was being caned, "for asking, er, to punish, er?" She trails off, but you suppose it's good enough.

"Try again, girls," you order brusquely, lying back to give them access, but keeping the cane close at hand in case it's needed in the future.

The girls apply themselves to your pleasure once more, while the weals on Yuina's rump start to swell.
