It's a shame that these slaves were brought into Bisanthium just today, else they might have known Luna. Unfortunately, they just see it as more lies, and as adding insult to injury.
Julia is doing a fine job soaping up Rilina's firm belly, making frequent trips in and out of her navel. "Such a dirty rich girl... we will get you nice and clean, won't we Martina?"
Martina is doing equally well in cleaning the poor apothecaries' armpits, lightly prodding and circling, and also taking time to tease her ears and even under the chin. "Look at her smile, you can see this rich girl is used to being taken care of, can't you Lanya?"
Lanya, meanwhile, is scrubbing and scratching at Rilina's soft soles. She rakes at them with the brush, and digs in between each toe with her fingers. "Oh yes, and we will get all this dirt off... like here (brushybrushy) and here (brushybrushy) and of course in-between here. (skritchyskritch) Because important rich girls just CAN'T be dirty, oh no!"
Even with all of them tormenting Rilina, they don't merely want her to shut down under the tickle torment... oh no. They want her to howl and suffer. Being tickle toys themselves, they know just how to tease her so Rilina will squeal ever so sweetly, but not so much that she escapes within herself. As they think Rilina is some wealthy girl playing at tickle-games, letting her know the full torment that three ticklers can inflict is their goal. They're doing a fine job.
"Well now, I think we've cleaned our Miss Kitty up, so-- oopsie!" Lanya accidently on purpose pushes Rilina onto the dirty floor. Julia and Martina lead her about with tickly prods and tweaks so that by the time Rilina is back on the bench, she's even dirtier than before.
"Oh well!", says Julia, "We will just have to start all over, won't we girls?" And as they get fresh coats of soap on their hands and brushes, they full well intend to do exactly that.
