In Pauline's mouth Traveling the Multiverse chapter 10 by dellobenedetto

When the girls separated, you found yourself in Pauline's mouth, the Purugly's tongue curling around and licking you delicately. "Hah! Seems I got him," she noted, playfully poking her girlfriend's shoulder.
Sammy, for the most part, just shrugged and rolled her eyes. "This time, maybe, but I know there's gonna be plenty more kisses for the little guy in the future."
"Better up your game then, babe!" Pauline laughed around you, "Else I might end up having him a lot of the time!"
"...You're very good at speaking with your mouth full," you noted once her tongue had settled down, giving you a chance to grip onto the taste buds.
"Really?" Just in time for Pauline to continue speaking. "Pfft, having you in there is nothing! Sammy and I have both managed to hold full conversations with an Alcremie in our mouths!"

A sharp ping resounded, making Sammy dig around in her sweatpants for a phone. "Huh, speak of the Gira'... Text from Alice. She's asking me to pick her up from her acting troupe's meetup."
"Aw, let me guess, she's stressing out over how rehearsals have been going and needs a big, sexy Snorlax to lick her cream and gulp her down?"
"Hah! Got it in one." Guess Alice is the Alcremie Pauline was talking about. Sammy smacks her gut, making it wobble almost hypnotically. "I swear, I've been doing that for her since her college drama club days, she probably wouldn't have gotten this far without me!"
"That indeed. You go on and get her then, I'll stick around and keep the tiny ready for you."
"Hope you don't mind another gal dropping by, little guy!" Sammy called out as she pulled on a coat—one that barely reached down past her waist—and barreled out the door like she was about to break into the Pulverizing Pancake Z-Move.

With her gone, Pauline gave you one last lick sliding across her whole mouth before slipping you out and into her palm. "I bet you'll love Alice when she shows up," she noted, "She's about your age, if I understand human aging right, and she's not just sweet in looks." She rolled onto her feet, with a hearty creak from the couch as she stood. "So! What should we do while we wait for Sammy to come back? I could show you the bedroom, or take a quick bath—ooh! Or how about a trip beneath my paw pads? They're quite comfy, from what other humans have said~"
"Uh, l-let's see..."
