Returning one late evening with the burden of life on my shoulders, I spotted a small unlabeled cardboard box in front of my door as I was approaching my home. Picking up the box in my hands, it was surprisingly light and I hoped that whatever in there could cheer my dull life up. Placing it in my living room for the time being, I did a quick clean up and returned to the box only in my boxers, tearing it open in anticipation.

Pulling out something vacuum packed in a plastic, I ripped a corner and the compressed item gained its shape. It turned out to be a tan-colored teddy bear plushie that I could hug for comfort. At the bottom of the box was a note, “Sleep with me and you’ll be cuddly for the rest of your days!” The note ended with a red heart-shaped stamp. Taking the plushie to bed with me, I stared at it and it felt so surreal. It was the first time in many years since I slept with a stuffed animal after I had given my childhood bear plushie away, which just happens to have the same appearance as the one in my arms. Treating the plushie like my childhood toy, I snuggled with the teddy bear in my tight embrace, pressing the fuzziness of the toy against my bare chest, and dozed off with it under my blankets like old times.

Waking up with a big yawn, the night had gone by without a hitch as I slept like a baby. But something felt off. The bear plushie I had clasped all night was gone and there was some kind of warm and squishy sensation around my waist! Peeling off the blanket, my boxers were missing, now replaced by a thick diaper-looking fleecy garment with the bear head of the teddy bear plushie at the front. It was not crinkly like a normal diaper as it was made of layered fleecy fabric with tightly-packed stuffing inside, and it felt more like a plushie was hugging my waist. At the back, it had a small puff of fur above the rear as a tail.

“Hi there!” The fleecy garment said, its bear mouth moving right in front of my privates. I screamed for a moment before calming down.

“W-what are you?” I questioned.

“I’m your bear underwear, or an underbear if you may, here to keep your precious parts safe. And…”

Suddenly, I had the strange urge to relieve myself out of both ends. I dashed toward the bathroom, only to discover that I could not remove the bear underwear, at least not in time. I felt my pee spill out the front and my crap exit through the back freely like a torrential flood, my bladder and bowel control both compromised.

“Mmm! I love it!” It uttered as it absorbed all my mess quickly, leaving a warm, dry and plush sensation on my front and rear. “By the way, I’m a teddy bear diaper!”

“Would you get off me now?” I tried to tug it down, pull the edges of the diaper, tearing at it and even feeling for the tapes that a normal diaper had. None of the methods of escape worked.

“Nope. I’m bound to your body, so you can’t take me off no matter what,” the bear diaper said, forcing my hips to wiggle side to side. “Let’s go outside and grab something to eat! I can sense you’re hungry.”

Sighing defeatedly after much futile attempts to remove the bear underwear, I pulled on a hooded sweatshirt and a pair of long pants over it, the diaper bulge protruding a little. “Are you sure people won’t see the obvious diaper shape in my pants?”

“Don’t worry. They won’t be able to see me.”

Walking with a diaper made of plush instead of plastic, it did not emit loud crinkles and did not restrict my movement between my legs. It was like as though I was wearing two layers of underwear at once, tight and comfy. Entering a nearby restaurant, I got myself some pancakes and coffee for breakfast. Halfway through my meal, I felt my body let go again unintentionally, creating more mess in the diaper. Oblivious to me, the diaper was growing each time a mess was made, slowly filling up with more and more cotton. Upon finishing my filling breakfast, I stepped away from the table only to see many customers of the restaurants darting toward my waist, and I could tell that they could see the bear diaper. And looking down, it became more evident than before, the bulge now shaped like a huge piece of popcorn in my pants. I sprinted home with eyes drawn on me as my dignity was gone in a snap.

Back home, I took off my sweatshirt and proceeded to pull down my pants, noticing one more thing – the diaper had grown with layers of tan-colored fleece covering my upper body. The fabric had reached halfway down my shoulders and thighs like a fuzzy bathing suit. I panicked immediately, pacing around my living room and searching for a pair of scissors to cut myself out. I had enough of the plush diaper. Once I had located a pair, I snipped at the fleecy sleeves around my shoulders, only to have the scissors turn into dust.

“Hey, I’m a magical diaper, so whatever you do won’t work… Oh… You’re already trying something else,” the bear diaper remarked, seeing me try to saw the fabric off with a knife. The same thing happened with every sharp object I tried. Giving up on freeing my crotch from the bear underwear, I headed to my room and sat on the edge of my bed, staring at the teddy bear head on the front.

“Stupid bear diaper thing!”

“I’m not stupid. If you wanna enjoy me more, you have to relax…”

Somehow, the words made me lose my bladder control as my pee splashed into the plush garment, absorbed again instantly without fail. In the next moment, I felt a wave of drowsiness and sprawled on my back, dozing off in seconds as the diaper made me nap throughout the late morning. While I was sleeping, the fleecy fabric flowed down to my fingertips and formed mitten paws over my hands. For my legs, it spread all the way to my toes like a pair of fuzzy stockings. The bear head on my front migrated and emerged as a bear hood behind my neck, flipping and wiggling itself onto my head, leaving only my face open as it tightened so that I could not pull it off my head. With most of my body encompassed in layers of fleecy fabric, every muscle eased up and my quickened heart rate slowed down for me to sleep better.

When I woke up, the softness pressing on me was comfy, almost too comfy. I sat up immediately to find myself head to toe in a fleecy outfit, but the diaper bulge was still at my waist, like an integrated diaper of the costume itself. Feeling the two fluffy round ears on the hood on my head, I knew I was put in a bear onesie. Staring at the obvious diaper shape on my front, I realized that the bear head had disappeared as I poked it with my mitten-covered hands.

“I’m up here silly!” The hood exclaimed into my ears, making its presence known to me.

“What the f-” My voice was cut off by the movement of my fabric-covered hand jamming between my lips momentarily.

“It’s fluff! Don’t swear, my little cute cub!”

“But, why am I now in a onesie?” I tried to pull back the hood, but it would not budge. There were no zippers to escape it either.

“Because you’re adorable in it! Time for you to go potty in me again!” I felt more of my messes slip into the stuffing-filled diaper of the bear suit and the head giggled as I blushed, the warmth on my cheeks in embarrassment felt by the edges of the fleecy hood. “Alright. You’ve had your fun. It’s time for me to show you my full power!”

Before I could protest, the hood shuttered onto my face, muffling my screams for a moment as the hood thickened. During one of my cries for help while my mouth was open, it forced a giant rubber pacifier between my lips which plunged straight into my throat, muting my voice completely. I could still see my room through the fabric eyes of the outfit, but sight was not important as I had my priorities. Feeling at the front of my face, there was a thick teddy bear face in front and I could only grab at the plushiness of the bear snout, unable to pull the pacifier out. As I grinded my teeth at the pacifier in defiance, warm milk splashed from the pacifier into my mouth. Even when I stopped biting, the milk kept pouring, my body fed constantly by the suit. I laid in bed, unable to move as the milk the suit was feeding me was also making me relieve myself ceaselessly, increasing the outfit’s puffiness the more I let go, converting all my messes into plush stuffing to thicken its belly and stubby appendages.

“Thaaaaat’s better…” The now living teddy bear outfit cooed, taking control of one of my mittened hands to give me a rewarding belly rub, soothing me in a circular motion.

Staring at the ceiling through the fabric mesh of the bear’s eyes, I was reminded of the note I had seen the day before, the words “cuddly for the rest of your days” echoing in my head. The new teddy bear suit had indeed made me cuddly. Stuck inside the sea of stuffing in the human-sized teddy bear, I laid on my bed comfortably as my worries were slowly drifting away the more I let go.
