It's a relief that the slime's enjoying her stay inside Eurikova's digestive tract, and as they move towards their destined rendezvous with the drow the naga's slithering grows occasionally erratic and her face flushed as a particularly emphatic push distends her tail enough to give her a wave of pleasure down the length of her tail. Still, she doesn't comment on what the slime's doing in there, and when her stomach contents register a soft wordless noise of pleasure instead of an attempt to get out the ninja shrugs, bites her lip, and keeps on slithering unsteadily. Her tail had been evenly thick throughout, but as time passes she relaxes enough that it takes on a lumpier shape. Not the sequence-of-fixed-bulges lumpy that a person makes inside a stretched tail, but a more chaotic, irregular bulge that shifts and rearranges itself randomly according to Phylia's whim.<br/><br/>Inside, her stomach's reaction to a countervailing massage is energetic and enthusiastic. Whatever Eurikova's commitment to not doing too much to a willing guest whose tactical support she'd need later, her stomach knows what it's supposed to do with something moving around in there.  Her stomach walls begin kneading the slime more and more energetically, pushing up and down the length of Eurikova's tail and having the effect of mixing Phylia together as homogeneously as the slime's constitution allows; there's not even a single pause for the slime to catch her metaphorical breath between muscular contractions. There's even a bit of acid leaking from the naga's stomach walls, though it's not nearly as intense as it would be were the naga not stubbornly holding herself back. Instead, the warm liquid mixes into the slime's form as churning motions coax the stomach contents together, making the slime slightly more acidic- albeit with Eurikova's own juices worked into her form. A little cross-eyed, all Eurikova can do is follow along behind the others, occasionally belching a little as her stomach kneads out small bubbles of air left in her belly and looking fabulously pleased with herself.
