"...Can you gather up some of the gems that're in my pussy with you?"

"What?" Hearing that took you for a loop. "You... store gems in your womanhood? ...O-oh right, you mentioned that before."
Rouge's answering giggle reverberated around you. "That I did, kiddo! It's easier to just stuff them inside me rather than risk them falling out of or being searched through in a bag. Plus, the shapes of them feel just so... good when they shift about in there. But I can't have them in there all the time, you know. Don't want them to distract me during my more vital work."
"Oh, f-fair enough." You cast a slight glow spell from your hand, illuminating the womanly folds around you more than the light diffusing through the many layers of skin.
"I'll wait on my bed, to give everything a soft exit. Take your time~"
You decided to do so, crawling deeper into Rouge's body, taking in just how cavernous the bat's insides appeared to be. And sure enough, there were gemstones glittering all around you, enough so that someone might mistake her womb for an oddly organic mineshaft. You freed all the ones that were lodged in the folds, pushing them back the way you came and relishing Rouge's resulting coos. Goodness, if these all came from separate heists... you were absolutely astonished. And who knows if she's put gems elsewhere in her body?

Eventually, you got the massive pile of gems back to the entrance, and debated whether to nudge them back outside one at a time... before just going all in and pushing the whole pile, making Rouge yell out in ecstasy as she birthed a whole pile of gems at once. You ended up tugged out along with them due to how energized her womanhood was, as slicked in juices as the gems as you flopped out weakly onto the end of Rouge's bed.
You gradually turned to look at her. Panting heavily. Naked body on full display. Wings fluttering weakly. Her breasts dripping with milk. And her slit wide open, fingers slowing its close. "Hoo... That... that was wonderful, kiddo. You're... you're a natural at this..."
"I-I'm guessing you normally rely on yourself to, heh, get them to come out?"
She chuckled faintly at your joke, picking up one of the gemstones. "Yup... a lot of them tend to get too stuck inside to leave... This one I put in there, what, two years ago? I forgot how strikingly purple it was... But not its shape, by any measure."
The two of you both laughed at that, and she set it down. "Now then," Rouge began...
