Kerrin vaulted over the metal bench and made a beeline for the figure huddled in the corner, her nose deep in a book about… something. Kerrin didn’t wear their glasses today.

Approaching the engrossed brunette, they gestured to the place directly next to her and asked, "Can I sit here?"

The reader jolted. Her nose withdrew from the book as a frown settled on her face. "No," she huffed shortly.

Undeterred, Kerrin continued, "Okay, how about here?"

The girl frowned impossibly deeper, "That's my lap."

Kerrin rolled their eyes, "Yes or no, you prick."

They watched with rising joy as the trademarked scowl made its way onto the girl’s face. Gods, they loved pissing off Laura. It was so easy! She’d made it very clear, long ago, that the two of them could never coexist peacefully. Kerrin had grown to revel in the unique and surprisingly vast range of scowls and frowns they could pull from the other.

If Laura was so determined to hate them, why not have fun with it?

The girl in question rolled her eyes viciously, “Like I’d allow your bony ass anywhere near my lap, you cretin.”

Kerrin grinned. Let it be known, it was by no means a friendly grin. No, it was self-serving and predatory. Like a hunter watching prey fall right into their trap. She’d walked right into it.

“Well, well, well!” they crowed gleefully, “How titillating to know that my ass has been on your mind! Interesting choice of word, you have there: bony. Not scrawny, not voluptuous, not thicc, but bony… You must've been studying my ass and its interactions with laps very closely! ”

Laura’s scrawny lips almost disappeared in the affronted thinning she put them through.

“It is quite an exemplary ass, I admit,” Kerrin drawled, “I never took you for an ass girl, my sweet! That juicy piece of information is my new learned fact for the day!”

Egged on by the other’s silence, they continued their fanfare, “It changes things up quite notably to know you’re admiring my ass from afar! I shall have to consult my wardrobe! Mayhaps some scandalously high booty shorts are in my near future…” With a suggestive eyebrow waggle, Kerrin continued, “Please know, my dear Laura, that the next pair of booty shorts I don, I don for your eyes, and your eyes only!”

Laura scoffed loudly. She closed her book with a loud slap and narrowed burning eyes at Kerrin. “You’re ridiculous. An absolute fool,” she hissed.

Kerrin grinned. They leaned their face close to the startled brunette’s, lips moving a hair's breadth from the girl’s as they whispered sweetly, “And yet, my darling Laura, I’m yet to hear you deny any of it.”

The brunette stuttered for a beat while Kerrin’s grin deepened. “For someone who’s meant to hate me, you spend a suspicious amount of time apparently looking at my ass, and you curiously refrain from denying you do so, despite multiple opportunities.”

In a moment of bold stupidity, swept up in their heated exchange, Kerrin closed the miniscule gap between their faces to suck Laura’s quivering lower lip into their mouth and nibble it. They released it a breath later, pleased to see the rising flush on her face.

“Not bad,” they breathed thoughtfully. “You don’t taste as bitter as I assumed.”

Kerrin straightened their back and began waltzing away from the frozen girl. They turned...
