Sophie and Mirlo by Imouto Kitten

Mirlo, princess of the Waterdrop Kingdom, was feeling more nervous than 
usual. Her good friend and fellow princess, Sophie of the Windmill 
Kingdom, had invited the shy beaver girl to the Windmill Castle for a 
sleepover, and despite her reservations, Mirlo had been unable to tell 
the outgoing and exuberant half-doggle no.

Unlike the princess parties it was just the two of them, which helped 
put Mirlo's social anxieties at ease, but the more intimate setting soon 
proved a double-edged sword when Mirlo saw her friend's choice in 
sleepwear.

While Mirlo was dressed in frilly silk pajamas the same pale blue that 
dominated her princess gown and consisting of a long sleeved nightie 
that reached her knees and bloomers that reached her ankles, Sophie was 
wearing a far more revealing outfit Mirlo doubted even the twin 
princesses of the Sunny Kingdom would wear to bed unless they were 
spending the night in the Flame Kingdom.

For Sophie was wearing nothing but a pair of purple spandex shorts that 
hugged her hips and butt snuggly and a white crop top that barely passed 
the bottom of the ribcage. The Half-doggle's wagging tail was even on 
display! Mirlo owned undergarments that covered more skin than her 
friend's choice in sleepwear.

And as much as Mirlo tried not to think about how pretty her fellow 
princess was, seeing the half-doggle so exposed and in clothes that 
didn't make it hard to imagine what they did conceal, Mirlo was having a 
hard time not reacting.

Like her mother before her, and her mother's mother before that, and as 
far back as the Matrilineal Waterdrop Royal Family could trace, Mirlo 
had been born with a little extra between her legs, and despite her best 
attempts to think of anything other than Sophie's scantily-clad body, 
the shy half-beaver was already at half-mast and struggling to not 
visibly tent her pajamas.

"Is something wrong, Mirlo?" Asks Sophie, her canine heritage on display 
through the way she tilts her head, "You're even quieter than usual 
tonight."

"N-no, n-nothing's wrong." denies Mirlo unconvincingly, unable to keep 
her cheeks from turning pink under the half-doggle's scrutiny.

"Oh, come -on, Mirlo, I can keep a secret." replies Sophie, not 
believing her friend's denial, "Are you thinking about a cute boy?"

"O-of course not!" replies Mirlo, though this more honest response does 
nothing to diminish Sophie's curiosity.

Wiggling her fingers, Sophie pouts, "Come on, tell me." and when her 
fellow princess remains silent, the half doggle tackles Mirlo and starts 
tickling the half-beaver.
