CW: toy play, but not the kind you'd expect, not canon, age gap (implied)

Kirishima buys the newest Ground Zero action figure. Gosh, GZ is so incredibly manly! Kiri hopes he can be half as awesome as his favorite hero some day.

A few days later, the package finally arrives.

He grabs it from the front porch and hold the box out, grinning widely. He's so excited! This is supposed to be the best Ground Zero figure ever produced! His friends told him that everything is accurate to a fault, and he can't wait to open it and put it together.

Kirishima clutches the box to his chest, squealing and jogging in place in glee. He's glad no one else is home to hear his super unmanly giggles.

"Yes, yes, yes!!"

After locking the front door, he races up to his room to inbox his prize.

Kirishima tears the brown box open.

Inside is a pristine box covered in photos of his hero. Explosions and other manly images pop in the background, and on the front in big, bold letters, the box says, "#10 HERO: GROUND ZERO".

Kirishima squeaks at the first sight of the photo the figure is based on.

It's displayed across the front. GZ's uniform is torn, and one of his gauntlets is missing. The other is cracked, and his mask is missing entirely. Soot is smudged over one side of his face, and he's grinning like a maniac.

That's not what draws Kirishima's attention, though.

No, what gets his /immediate/ attention is the nipple proudly on display in the photo. It hasn't been censored, and Kirishima swallows hard when he spots the rumored bar piercing the pink bud. He /swears/ that's what it is, and as he carefully opens the box with shaking hands,+

he can't help but hope that the piercing is on the figure, too.

Just the thought has his dick swelling, pleasure boiling low in his gut. God, he wants it on the figure. He's heard that some of them have it, and some don't. It's a gamble which one he got, though.

His hands tremble as he fishes out the baggies containing the figure's individual parts. There's the stand and the hook coming off of it to support the figure in midair, and then Ground Zero's bottom half, his torso, and his head.

Kirishima inhales a sharp breath.

There, right in the tattered hole across the figure's chest, is a pink nipple...and the silver glint of a nipple piercing.

The breath he inhaled rumbles out as a needy moan.

He got it.

He got the version /with/ the nipple and piercing.

Oh, god. It's so hot.

Kirishima rubs his thumb over the nipple while the torso is still in the package. He feels dirty, naughty for touching his hero this way. Even if it /is/ just a figurine, he feels...so /sinful/, and it only makes his dick harder.

He reaches down to adjust himself.

When his hand grips his cock, he gasps. Wow, he's already super sensitive. Okay.

Okay, he can put it together fast. Then... then he's /really/ gonna get naughty.

He grins.

Kirishima tugs out the pieces, pausing only to gaze at his hero's bulging thighs and round ass.

He's not lucky enough to see a dick outline in this figurine, but that's okay. He can imagine it pretty easily. Sometimes it's better that way, anyway.

Piece by piece, he puts the figurine together. Once it's constructed, he rubs his thumb across the visible nipple again.

Saliva pools in his mouth, and he moans softly, imagining what the /real/ Ground Zero's nipple might feel like. There's a little bump to the figure, a slight raise, and touching with his thumb quickly isn't enough.

Kirishima lifts the figure to his mouth, exhaling a hot+

breath over the plastic skin and cloth. Heat swells in his dick as he imagines Ground Zero's /real/ skin puckering under his breath.

God, he could make it so good for the older man. He could be such a good, good boy for him.

So good. He'd give literally /anything/ to hear Ground Zero call him a good boy.

Kirishima licks his lips, then he pokes the tip of it against the plastic. His eyes roll shut, and he gasps as he feels the very slight bump. His hips jerk upward, clothed erection yearning for+

friction of any kind.

As he undoes his shorts, Kirishima drags his tongue over the half-naked chest, mapping the dips and swells of Ground Zero's body. He tongues lightly at the curve under his hero's pec before dipping lower to taste plastic abs.

Fuck.

This is so good, so incredibly wonderful. Kirishima wraps his free hand around the base of his cock, squeezing once. His pulse beats through his hand, and his dick twitches, the tip leaking precum.

He whines softly. "You taste so good." The words come as barely a breath.

Kirishima rolls the doll over so that Ground Zero's clothed ass is pointed at his mouth, and he licks a hot, wet line up the dip between the hero's cheeks. It's not super defined, but it's enough to give his mind something to cling to.

He kisses his way down one thigh and+

around it to the front as he slides his hand up to the tip of his dick. He rubs the underside of his cockhead with two fingers, using his precum to make it slick and smooth. A nasty, dirty moan pours from his lips, and he ruts upward into his hand, yearning for more.

As he turns the toy around so he can lick at Ground Zero's crotch, he imagines his hero's dick in his mouth.

He chokes back an especially lewd moan as he licks up the toy's inner thighs, the tip of his tongue catching in the tight area where the thighs meet.

His tongue catches every ridge and bump in the costume, and he groans. God, he wants this so badly.

Kirishima's fingers speed up as he kisses back up the figure's body, aiming for that pert, perfect nipple again.

He latches on this time, lips curling around more than half+

of the figurine's body. It's /amazing/. His lips feel every valley and hill of muscle beneath the torn outfit, and Kirishima does everything in his power to imagine doing this to the real man.

/Just imagine if I'd been able to clean him up after that fight with my tongue./

The thought of tasting Ground Zero's sweaty, sooty skin has Kirishima's balls lifting. They tense as heat shoots through his core. His toes curl. His ass clenches around nothing, and a moan rips from his chest as he cums across his hand and lower stomach.

Pleasure roars through his ears. His hands drop to the floor, and he gasps, his body trembling through the aftershock of his orgasm.

As he comes down, he checks the figure to ensure he didn't accidentally scratch it with his teeth.

No damage. Good.

He smiles as he runs his thumb over that nipple again.

Kirishima has a ton of Ground Zero figurines, but this one is /definitely/ his favorite now.

END

The twist is that the figure is the real Ground Zero. He was hit with a quirk that turned him into a toy for 3 days....and while he can't move or react, he feels /everything/ Kiri does to him.
