Spike starts to feel weird around Twilight and ends up swallowing her down in her sleep. Vore/endosama.

Twilight was asleep when Spike found her lying in bed. Good. That made it easier.

Why he wanted it to be easier, he wasn’t sure. Truth be told, he wasn’t sure why he was here at all. He only knew that for the past few days, he’d been hungrier than ever, hungrier than any gem could fill—and that Twilight had started to look incredibly delicious.

Carefully, he pulled the covers back from her sleeping form. He watched her for a moment, her chest rising and falling steadily as she slept. It was kind of cute, really. But watching her wasn’t making him any less hungry.

He started with her back hooves. He picked them up and gently dragged them to the side of the bed. He had to hop up onto the mattress himself to reach, but once he got the edge of her hoof into his mouth, he knew he’d made the right decision. A steady stream of drool trailed out of the corner of his mouth as he stuffed his jaw full of both hooves. He let his throat bulge out around them as he slid a few more inches inside, passing Twilight’s ankles and moving up to her forelegs.

His cheeks bulged greedily around Twilight’s rump as her legs slid into his belly. He felt his whole body tense and then immediately relax as the first part of her splashed down into his waiting gut. She tasted so good. His tongue lapped at her pleasantly plump rear—a librarian’s lifestyle didn’t lend itself to much exercise—as his jaw unhinged completely to take the rest of it in.

Twilight was squirming softly now, her muzzle contorted and her eyes squeezed shut. Spike didn’t mind, though. All he cared about was the growing bulge in his belly and the concentration he needed to keep his mouth wide enough to swallow down Twilight’s torso. His throat muscles worked steadily, working hard to take all of her in. His belly bloated out as her rump followed her legs, his throat bulging obscenely while his swollen stomach sloshed and churned around its oversized meal.

Twilight was shifting, muttering, squirming. She opened her eyes—then glanced back at Spike. Her eyes widened when she realized that his face was just inches away from her own; he’d swallowed down almost half her body by that point. “Spike!” she sputtered, shaking the sleep away. “No—stop!”

But Spike wasn’t listening. He greedily gulped the rest of her abdomen down, then started on her shoulders. Twilight was struggling, squirming against him, but the suction of his throat and power in his bulging jaws was too much for her to resist. She slid down, inch by inch, until just her neck and face were left in the air.

Spike’s jaws opened even wider for her shoulders. Then, with a final, echoing gulp, he swallowed the rest of her down.

His big, round belly ballooned outward in front of him. He plopped down on his butt and groaned, listening to the gurgling of his happy tummy as it went to work digesting this new offering. Inside his engorged stomach, he could feel Twilight pushing against his digestive walls. Occasionally, a hoof would bulge out against one of the sides. He could feel her kicking, thrashing, punching inside, but to him it actually felt rather pleasant.

Spike just rubbed his large, round, overstuffed belly happily. The little dragon’s stubby claws couldn’t even begin to reach halfway around the massive thing, let alone all the way. Instead, he was happy just to hug it, nuzzling his snout against his sloshing, squirming gut as a profound sleepiness overtook him.

Some hours later, he drifted back into consciousness. Blinking drowsily, he prodded his gut a few times. It had shrank down to a much more manageable size, though it was still quite soft and hung over his waist by more than a few inches. There was more than a small layer of pudge on him now; his whole body was a lot more squishy, with his midsection forming a pouch in front of him and his cheeks puffing out as well. He felt under his neck, and found that he even had the beginnings of a double chin.

Huffing, he heaved himself to his feet. There, he found, that he’d grown taller as well as wider—no longer a baby dragon, he was now around the same height that Twilight had been when he’d swallowed her down, if not a few inches taller. He made his way over to the mirror set into Twilight’s door, waddling a bit as his thick thighs rubbed against each other. He watched his big gut bounce and jiggle with awe, savored the image of his padded butt bouncing a little with every step. His fat belly hung down a bit over his thighs, and was incredibly soft to the touch. He massaged it for a few seconds, just taking in his new, larger, heavier form.

Spike patted his stomach happily. He didn’t even feel hungry anymore. He was completely and utterly full. Looked like eating Twilight had done the job.

And yet...somewhere in the depths of his fat, round gut, he felt a small gurgle of hunger. A lazy grin crossed his chubby cheeks.

Well. Maybe not entirely full. He wondered if Pinkie would have any treats available at Sugarcube Corner.

And whether she might not be as sweet as her cakes and cookies.
