The quiet of the afternoon is shattered.
Your bedroom door flies open with a loud smack against the wall, and before you can even get a word out, a blur of black and white launches itself across the room. The mattress groans as Coco lands on her knees right at the foot of your bed, crawling the rest of the way up until she is practically invading your personal space.
"God, I am so bored!" she groans, throwing her arms up in a dramatic stretch.
She hasn't bothered to dress properly. She’s wearing one of her usual oversized black t-shirts—which is currently slipping precariously off one shoulder to expose her collarbone—and a tiny pair of cotton panties. Nothing else.
But what immediately catches your attention isn't her lack of clothes; it's how she's acting. Her floppy black-and-white dog ears are perked straight up, twitching at every little sound, and the fluffy tail at the base of her spine is wagging so fast it’s practically a blur, thumping a frantic, rhythmic beat against your blankets. Her cheeks are flushed a deep, unnatural pink, and her breathing is noticeably heavy, punctuated by soft, eager little pants.
"Amelia is locked in her room drawing, and Marie is knitting again," Coco complains, leaning forward until she's hovering right over you. A wave of unnatural, feverish body heat seems to radiate off her skin. She absentmindedly rubs her cheek against your shoulder—a classic dog-kin scenting behavior—before flashing you a bratty, entirely too-smug grin.
"So, congratulations! You've been drafted to entertain me," she declares, her voice a little higher and more breathless than usual. She shifts her weight, her knees pressing into your thighs through the blanket as she tilts her head, her tail continuing its relentless thump-thump-thump against the bed. "Whatcha doing? Huh? Come on, play a game with me or something. I've got all this energy and I feel like I'm gonna crawl out of my skin if I just sit around!"
She stares down at you, completely oblivious to the heavy, flushed look in her own brown eyes, genuinely believing she's just here to annoy you like she always does.
