It's okay, she gave me permission to write this awful self gratification.

Love you Minzie <3 <3 <3

Deku's hand shook as he pushed open the door, a tiny bell tinkling above his head as he stepped in. He took a deep breath, steeling himself, burning crimson when the storekeeper called out a bright welcome.

"Can I help you find anything?" she asked pleasantly.

"No thank you!" he squeaked back, shaking his head wildly. "Just looking!"

There were few customers inside, which he'd somewhat expected in the middle of a work day anyway. While he didn't like the lack of money that came with a day off, it did make it much easier to perform some of his more private activities discreetly. He'd taken a train to the other end of the city just to avoid the possibility of running into someone he might know, and now he stood in a superstore of scandalous seductions, stunned by the sheer selection for sale. 

He scuttled down to the right section, face still heated, trying his best to calm himself – to stop his hands from trembling, to focus his vision. There were so many of them! How was he ever meant to pick one?!

Half of them looked inhuman, compared to his own dick. Did people really have penises that long? That... girthy?

Not to mention the colours.

He didn't realise how long he'd been staring until a sweet-looking sales associate approached him, smiling gently.

"Do you need any help, Sir? I know it can be hard to know where to start."

"Eep!"

"We're here to help!"

"I- I- Uhh, I'm- Uh, l-looking for..." he blushed again, ducking his gaze. "Um, s-similar to... someone."

"Of course! Did you want vibrating or penetration?"

"P- P- Th-The second one."

"There's nothing to be ashamed of," she assured him, leading him further down the aisle to a shelf of colourful toys. "What kind of size?"

"He's b-big. Um. This big?"

He held up his hands to demonstrate, and without a hint of shame the lady plucked one off the shelf, holding it up in a way that almost, almost looked lewd in itself.

"Does this look about the right size?"

"Uhh..." He looked away, rubbing at the back of his neck awkwardly. "Thicker?"

"Okay, how about this?"

"Y-Yeah, that's closer," he agreed, when she picked up another toy from the selection.

"Okay, take a look at this shelf here then, they're all around the same size. Is there one that stands out to you?"

Deku slowly lifted his gaze from the ground, blocking out the monstrosities around him and focussing on the one shelf she gestured toward. He still shook, but he managed to sweep his eyes over the collection, pointing awkwardly at a neon green contraption – it was around the width of three of Deku's fingers, although now he wondered if that was an exaggeration in his memory. It looked huge in front of him. It was curved just right, and had a nice swollen head that he could practically feel inside of him. 

"Th-That one is g-good, only, um... Do they... Can I..."

He trailed off awkwardly, and the lady smiled.

"You want a different colour?"

He nodded faintly, and she crouched down, opening a little cupboard full of boxes. 

"We have red, blue, green, orange, black, white, and a few different skin tones."

"Oh jeez, uhh, skin-toned," he stumbled, face burning again. "The others seem..."

"I understand," she chuckled, pulling three boxes from the cabinet. "Which of these is closest to your man?"

"Um, the pale one."

She slid the two extras away and he awkwardly picked the box up – it was a massive box, why did it need to be so big for one toy?? And why did it need to have a giant picture of the thing on the box?!

He followed the lady to the counter, digging out his wallet to pay, eyes growing wide when she placed another little box beside it.

"These are on the house," she assured him. "Just some nice cleaning tools and things, make sure you follow all the cleaning directions!"

"Th-thank you! I will!"

He handed over the cash and breathed a sigh of relief when she bundled it all up in unassuming brown paper, slotting it into a black plastic carry-bag with no discernible logos.

"Thank you for your purchase, Sir! Please come back for any future needs!"

"Y-Yes! Thank you! For h-helping!"

He tucked the bag under his arm and hurried out the door, walking at a brisk pace to put as much distance between him and the toys as possible. He realised much too late that to any onlookers he probably looked eager to get home and try it out, and he let out a quiet whine as he fell into a seat on the train.

But at least he hadn't seen anyone he knew.

Izuku stared at the toy in front of him, as if he could stare into its soul and somehow make it less intimidating. It was nearly perfect, almost an exact replica of Kacchan's monster cock, but something about it just seemed... off.

"You're not Kacchan," he grumbled, picking up the cold dildo and holding it in his fist. "It's not the same."

Out the corner of his eye he spotted a merch collection, and before he knew it his feet were taking him over to the shelf, eyes scanning over the items. Action figures? No. Hoodies? Closer, but no. Keychains? Definitely no. Plu-

Plushie.

He picked the Ground Zero plushie up with his other hand, contemplating, looking from the squishy doll, to the dildo, and back again.

"Fuck it," he mumbled. "Why not?"

He poked at a seam on the toy, debating tearing it open to connect the two, but the idea of intentionally ruining his merchandise was even more heartbreaking than the idea of not getting fucked in the first place. Instead he dug out a roll of duct tape, positioning the two together just right and taping them in place.

What kind of sick fuck was he?

He set the plushie on the ground, staring at the little stitched smirk and the ruby-red eyes as he trickled lube over the dildo, hand running smoothly up and down the shaft.

"What's all this, Deku?"

For a moment he could have sworn the plushie had spoken, but the neat little black stitches never parted.

"Need me so bad you're gonna play with your toys again? Fuckin' pathetic little slut."

Deku moaned, lubing the toy a little quicker, and in his head he heard a familiar cackle.

"Look at you, already hard just thinking about it. Can't go a damn week without my cock in your ass, is that it? Fuckin' quirkless nerd, only useful as a nice, warm, desperate cock sleeve."

He fumbled his pants off, turning around and sitting up on his knees, reaching back to position himself just right. 

"Yeah, that's it, you whore. Shove that whole thing up your ass real good and slow. Moan my name, slut."

"K-Kacchan," he whimpered, as the head pushed painfully through his entrance – he knew he really should have prepared himself more, but Katsuki wasn't gentle, he didn't want gentle. "Kacchan!"

"Keep going, fuckin' nerd. Get yourself off on a fuckin' plushie with a monster cock."

"Kaccha-an, feels so g-goood."

"Damn fuckin' right it does."

His own dick was full to bursting, swollen and angry at the lack of attention, but Deku couldn't bring himself to touch it. Katsuki wouldn't let him touch it.

But Katsuki wasn't here, right? Not really. He could just...

"Don't even think about it."

He whimpered, but retracted his hand all the same.

"I'll be g-good, Kacchan," he promised, as he sank a little lower. "So good for you, Kacchan. Just f-fuck me, please!"

"All the way down, Deku. Now."

He bit hard on his lower lip, nodding as he sank down to the base. A short, sharp gasp escaped his tormented lungs as it filled him up just right. It was so good, so perfect, felt so much like his Kacchan he just needed to-

"I told you to keep your grubby little hand off your pathetic little dick," the Katsuki in his head reminded him. "Am I not good enough for you, slut?"

"The best, Kacchan! I swear! I promise I won't touch! Not until Kacchan says it's okay!"

"Only good boys get to cum, Deku. Not naughty little bitches."

"I'll be good! So good!"

"That's what I like to hear. Fuck yourself real good on me."

"Y-Yes, Kacchan! Anything for my h-hero!"

"Fuck. Yes."

He held his breath as he rose up on his knees, leaving himself achingly empty. He waited until just the very tip was left inside him, just enough to aim, like Katsuki would do – teasing him, stroking his hole, waiting for him to beg.

"P-Please, Kacchan? Ground Zero, please?"

"Hard and fast, nerd. Don't fuckin' stop until you cum all over yourself without even touching your filthy little cock."

"Yes, Kacchan! Thank you!"

He dropped back down, struggling for air with the impact, but then he was rising again, falling again, rising- Hard and fast, just like Katsuki ordered. He would be good, he would be so good, just like Kacchan wanted. His flushed cock bobbed with his movements, up and down just like his hips, his thighs burning. His whole body flooded with warmth, burning hot as he angled his ass, presenting himself just the way Katsuki liked, imagining the little smirk and the long moan that would come from his childhood friend as he-

"Cum, Deku. Now, you little slut."

"Kacchaa-aan!"

He spilled his fluid all over the floor, wide-eyed as his pace slowed, fucking himself through the last of the spurts. There was no Katsuki, just an old plushie, a new dildo, and an embarrassed little cock sleeve with a sticky mess on his floor.

"Kacchan," he whispered. "K-Kacchan."

His phone lit up from the bedside table, and with a long sigh he clambered up, cringing at the ache in his ass and hips. He fell onto the bed, resolving to clean up the mess after a nice nap. The phone buzzed again, and he reached over clumsily, holding it up above his face.

2 New Messages: Kacchan!~

Did he know?! Was Katsuki spying on him?!

"Shooting for some new merch and thought of your cute little nerd ass."

The message was followed up by the most delicious photo Deku had ever laid eyes on – Katsuki, shirtless, abs and pecs on display in their full glory. His thumb was hooked into the waistband of his baggy black pants, showing off just a glimpse of orange boxers, and his familiar black-and-orange boots peeked in on one edge. Full costume, minus the shirt - perfect, really, if you asked Deku. What mattered the most, though, was the way Katsuki looked at the lens – the perfect selfie angle, of course, Katsuki was an expert after all, with red eyes leering up at him, the tip of his tongue poking out the corner of his mouth.

As Deku stared, the device vibrated again, and Deku reluctantly scrolled down to look.

"No answer, huh? You busy or somethin'?"

"Kacchan is so perfect!" he sent back quickly. "Signed posters please!!"

His heart pounded hard against his ribs as he waited for another response, smiling when the notification went off once more.

"I'll see if they'll print you a new fuck-pillow," he teased. "Gotta go work now. Think of me."

"Always!"

He set the phone aside, contemplating, and sneaked a glance over at the mess in the middle of his bedroom. Still the dildo stood tall and proud, strapped crudely to the smirking plushie. Those eyes stared at him, calling him, daring him, and he glanced at his phone again with a soft moan.

One more time couldnt hurt.
