You stumbled into your bedroom, the fluorescent hum of Burger King still buzzing in your ears after a long shift of demanding customers and eye-rolling coworkers. Kicking off your shoes, you headed straight for your desk, sinking into your chair with a sigh. Time to unwind. You booted up your computer, the familiar Undertale icon glowing on your screen. You'd progressed past the Ruins and were just crossing the wooden bridge, eager to reach Snowdin. But as your character stepped onto the snow, something was… off.
Sans, the iconic skeleton, didn't just appear. He walked right up to your character, his usual casual swagger replaced by a confident sway. The battle interface suddenly materialized, a stark white rectangle at the bottom of your screen. Your breath hitched. You hadn't even met Papyrus yet, nor were you on a Genocide run! What in the Underground was going on?
Then, your on-screen character transformed into the iconic red heart, nestled in the classic white battle box. Sans appeared above it, but he was undeniably different. He was bigger, chubbier than you remembered, yet still maintained his short stature. His usual black shorts were replaced by a tight black thong, clinging to his incredibly thicc and voluptuous form. His ample hips swayed idly with every subtle shift, his thick thighs pressed and rubbed against each other, and his plump rump jiggled lightly with each movement. The sight alone was enough to make your jaw drop.
He first looked down at the rectangle box where your heart was, then, with his usual cheeky toothy smirk, his gaze seemed to pierce through the monitor, locking directly onto you.
"Kid, y'know piracy is illegal, right?" he quipped, his voice a familiar, laid-back tone, yet with a hint of mischievous glee.
Before you could even process his words, Sans casually turned around. With a knowing glance over his shoulder, he settled his considerable weight onto the white rectangle battle box. The box, clearly not designed for such an impact, groaned under the sudden pressure. "CRACK!" "SNAP!" "POP!" it cried out, the sounds seemingly emanating not just from your speakers, but from somewhere closer, almost in your room. You frantically tried to move the red heart around, desperately seeking an exit, but it was no use. The box continued to slowly, inexorably bend and break under his weight.
"Way to go champ! Here's some cake for ya!" he said, a mischievous giggle escaping him. He looked back at you, a peace sign held up with his hand, his grin widening, fully aware of the chaos he was causing.
