On Yuina's tongue

Eventually, you decide it's time for the elder tourist to get a taste of spunk. You stop holding back and as you feel yourself approaching the peak, you give her a quick lesson on how to provide a satisfying tit job. Though not huge, her boobs are very nice and when you signal her to begin, she commences with more confidence than she showed while deep throating you. Now that she's not gagging on your dick, she proves more adept with lips and tongue and, combined with her girlfriend sucking on your balls, you have no problem reaching climax.

"Ahhh, keep going girls," you exclaim as you fill Yuina's mouth. "Just be more gentle than before, because I'll be extra sensitive for a bit."

Rather than reply, they simply follow instructions, delivering eminently acceptable post-orgasm care as you shrink and soften. You don't even notice any gagging when your cum is swallowed and neither of the lovers shows any impatience to finish, even after several minutes. You relax, but having caught your breath, there's one more thing you want to try.

Without warning, you start to pee, curious to see Yuina's reaction. To your surprise, other than a startled yelp, she offers no complaint, instead closing her lips more tightly around your shaft and gulping down the pungent stream. Her eyes do start to water a little at the strong taste, but she copes with the entire stream and even licks the last drop from the tip of your prick without prompting.

"Very good, girls. You can stop now. A bit more practice and I'm sure you'll both make expert cocksuckers."

"Thank, er, you, sir," the dominant replies, finally taking her mouth off your member, whilst her girlfriend murmurs something similar. "We, er, are grate, er, full for chance, er, practice, er."

Since small talk will likely be problematic, you settle for patting her on the head condescendingly and telling her you were happy to help, then you reach for your clothes. However, when your guests do the same, you have another idea.

"Wait a minute, girls. I think it might help you both to get the strict discipline you've been lacking if you spend the rest of your stay here naked."

They freeze, looking at you in consternation. Himari clearly understands the sentence (probably the first time you've been confident of this since you've met the submissive lesbian), although neither woman seems to quite comprehend what you're suggesting.

"Here, look, I'll send you an email explaining the situation, in case anyone's unhappy about you walking around in the nude," you promise, although in your experience nobody tends to mind punished girls going unclad.

You take their contact details, then they resignedly gather up the garments they will not now be allowed to wear, whilst you dash off a short note and add your professional information in case anyone questions it.

These ladies are tourists visiting our nation to learn about our spanking customs. They are spending their holiday naked to catch the attention of as many disciplinarians as possible, to ensure that they receive the severest chastisement.

You send the email, which both girls read, although from her indrawn breath, only Yuina seems perturbed by it.

"Thank, er, you, sir," they both say resignedly and you show them to the door, assuring them that you will check up on them before they return home.

You smile as you watch them leave, spanking implements prominently displayed, along with the marks of their recent use.
