Summary
     For the "Phantom Thief vs. Police" collaboration between Lancelot and
     POP'N STAR, Momo handcuffs Issei -- only to lose the keys. Mishaps
     and mischief ensue.
Notes
     Another commission for my dear friend! Lancelot and POP'N STAR's
     joined scouting led up to this moment. Let us all appreciate the
     opportunities that opened up for this fic thanks to that. Also
     someone please save Momo from himself (I love you so much, you
     precious child hhhhhhhhh).
     In case it wasn't obvious, there will be some underage sexy times in
     this fic, so please turn away now if that's not your cup of tea!
See the end of the work for more notes
When Momo thought about it, of course this kind of thing would happen. Of
course he ruined the photoshoot and forced it to be cut short because he’d lost
the keys to a pair of handcuffs.
Handcuffs. Who gave him those? He was dressed in a navy-blue skirt and a light-
blue shirt, a policecap on his head to complete the look he had for the
“Phantom Thief vs. Police” photoshoot that was a collaboration between POP’N
STAR and Lancelot. Handcuffs were an accessory for his attire, but within the
first few minutes of figuring them out, he had somehow shackled himself to poor
Ricky. Luckily, Runa remembered where the key was and freed them -- not without
the photographers taking some shots of Momo in his predicament, tears welling
in his large eyes.
Photographers had weird taste.
Back to the matter at hand though.
“I’m sorry, I’m sorry, Momo is so sorryyyy!” The tears were welling in his eyes
again. POP’N STAR’s dressing room was practically overturned, but nowhere in
sight were the keys.
Runa was standing there, in similar police attire to Momo, and he put a hand on
Momo’s shoulder. “It’s okay, Momo. We’ll definitely find a way out of this.
Luckily the photographers got the shots they needed from you two before
this...”
“B-But because of me, Issei-san is… Issei-san is--!”
“Oi, don’t talk about me like I’m not here. If you’re really sorry, hurry and
remember where you put those keys!” Loitering at the doorway to the dressing
room was Issei, in stylish clothing to go with his “thief” role that went
together with Kokoro. His hands were behind his back, but not in any humble
gesture -- rather, the situation was that in his paired shoot with Momo, he’d
been put in handcuffs… And thus the current situation.
Momo hiccuped back more guilty tears at the impatience in Issei’s eyes. He
tried so hard to be a good fellow I-chu and friend to Issei, had finally
thought he earned a soft spot in his heart -- and then he went and deteriorated
months worth of effort in five minutes.
Issei-san must really hate me… I’ll never stop being just a clumsy kid to him
at this rate .
Suddenly Kokoro’s bright presence filled the room, completely ignoring Issei
who scowled at his abrupt arrival. “Runa, come on back to the set, they want us
to be a pair. They said they’ll do more shots of us then take a break, that
should be enough time for the keys to be found.” Instead of chastising Momo
like he expected, Kokoro looked over at Issei like he just noticed him and
laughed. “I think I like you better this way though, you don’t swing your fists
around like a beast. Personally, you have my praise, Momo, hehe~”
“Why you--”
“Alright, alright~” Runa clapped his hands and milled himself and Kokoro out of
the room. “To the set then. You two do your best on your search, okay?” With
that, he closed the door behind them, leaving just Momo and Issei to the room.
Somehow, after his friends leaving, the despair and uselessness welled inside
Momo again. Apologizing would just earn him another snap from Issei, even when
all Momo could think about was nuzzling into Issei’s broad, warm chest so he
wouldn’t have to face the world and his blunders.
Holding back sniffs, Momo sank to the floor, away from Issei and busying
himself with looking on the floor for the key. He heard Issei sigh in
exasperation behind him, making Momo wince.
“This... Does Issei-san think Momo ruined the photoshoot. After all this
trouble...Momo probably misrepresented POP’N STAR too… Uuuuu…”
“You can’t search properly if you’re gonna cry,” Issei said gruffly.
“I know. I-I’m trying to stop,” Momo sniffed, unable to find strength to
correct his speech.
But to cause trouble like this is disgraceful, right?
When the sniffing didn’t stop, Momo lifted his hands from the floor to wipe at
his eyes. Luckily he didn’t have eyeshadow or mascara on like Kokoro, otherwise
a makeup job would just be another addition to the list of things he ruined.
Issei stepped closer -- Momo could hear his footsteps. There was a rustle of
clothes and the clink of the handcuffs, and then a large, solid warmth pressed
on Momo’s back. He opened his eyes, and saw Issei had sat down behind him, legs
on either side of Momo, surrounding him. Had Issei not had his hands cuffed
behind his back, Momo thought he might’ve been embraced, but it felt like Issei
was doing his best to make up for that.
“Hey,” came the deep rumble of Issei’s voice, “don’t put yourself in a panic
for something like this. You’re just a kid, no one expects you to be perfect.
You’re fixing what you did, so give yourself a little more credit and stop
crying, huh?”
“Uuuu… I’ll definitely find the key, Issei-san, and set you free!”
Issei let out an amused breath through his teeth. “You would make a godawful
cop.”
At first slumping his shoulders at the accusation, Momo turned to Issei,
looking up at him with what he hoped was defiance. “B-but! Momo caught Issei-
san, so Momo wins!”
“Haah?” Issei gave Momo a bewildered look. “It was for the shoot. If this was
real life, you’d never catch me. Or even that annoying leader of yours in his
heels.”
“Wha--!?” In a tizzy, Momo huffed and tried to circle his tiny arms around
Issei’s broad shoulders, but when that proved ineffective he moved up, his
hands meeting behind Issei’s neck. “See? Momo caught you again!”
“Did you?” Issei raised a confident brow, something of a smirk on his lips. His
face was so close, the light threads of his hair framing his eyes handsomely.
At that range, Momo swore he could feel the hot sigh of Issei’s breathing.
And then Momo was looking up at him, the ceiling lights shining up above.
Issei’s ponytail fell over his shoulder, and somehow Momo had kept his hold
around Issei’s neck. At the sudden realization that he was on his back on the
floor, Momo gasped.
“I-Issei-san…”
“See? I can capture you with my hands behind my back.” Issei’s voice was low,
the look in his eyes alluring, working just as well as if his large hands were
holding Momo down.
Let go. He should really let go of Issei and keep looking for the key to the
handcuffs, but… Momo’s gaze roamed, embarrassed to meet such a strong stare.
His hands followed his eyes, sliding away from Issei’s neck and down between
the open buttons of his shirt, his fingertips brushing against the exposed skin
of his collar and chest.
Warm… How can a human being be this warm?  Momo had had opportunities to
indulge in this warmth before when it was just him and Issei. Always, Issei’s
strong arms around him, making Momo feel safe as he snuggled against his chest.
Their size difference must’ve made them look so strange, but it was what Momo
liked best.
“We...captured each other,” Momo said quietly. Heat had risen hotly to his
cheeks, crawling down his body. In their hasty movements, his skirt and
petticoat had rode up his thighs. A weird feeling welled in him.
Positions like this… It’s what adults do all the time, isn’t it .
Issei was still staring back at him, silent, as if he were waiting. For what?
The longer that gaze held him, it was like Momo was under scrutiny, his actions
being gauged, dared to movement. And finally, Momo closed his eyes with all the
impulsivity of holding his breath before a dive, leaning up to kiss Issei. The
forceful gesture nearly had Issei lose his balance, but Momo pressed his palms
still splayed out on Issei’s chest.
A breath flowed between them when their kiss broke. Issei was cocking a grin.
“Forceful when you want to be, huh? If I stayed handcuffed, would you be able
to take the reins?”
Momo’s voice was quiet. “I… Momo could do it. You were captured twice by Momo
today, after all.” To reinforce his words, he wrapped his arms around Issei’s
neck again, pulling him down for another kiss -- several more, actually. It was
like he was running down a hill and he didn’t know how to stop nor did he
really know where he was going. All he knew was that kissing Issei was so  nice
. His mind grew dizzy from the soft heat of Issei’s mouth, the scent of his
cologne falling over him. When he broke the kiss again, he immediately buried
his flushed face into Issei’s collar.
Issei’s amused scoff ruffled Momo’s hair. “That’s about your limit, isn’t it?”
Momo shook his head, nuzzling more into Issei and making whimpering sounds. “I
-- I want to do more with Issei-san…”
“You’re trembling though. It’s making the whole situation look bad, y’know.”
Ah, well that was true enough -- if someone came into the room now, it would
look really bad. Momo wasn’t oblivious what he and Issei looked like together,
what this kind of relationship got called. But it was  Issei , who watched Momo
water the flowers and read in the library with him and gave him confidence.
Even when he screwed up now, Issei had comforted him.
Issei’s lips pressed into his hair, down to Momo’s cheek, his neck. Kisses slow
and sweet and soothing planted on his shaking shoulders, over and over until
Momo could feel himself relax. The touches were new, but it wasn’t scary if it
was Issei.
A spike of excitement made him squirm again when his clip-on tie was tugged off
and Issei’s mouth started to work on the buttons of his top. Using his teeth
and the push of his tongue, one by one, the buttons came undone, and Issei
nuzzled the shirt open.
“Hunh. They make you wear underwear like this too?”
Momo blushed, picking up Issei’s quiet hiss of, “ Christ ,” at the sight of the
padded white bra under his shirt. It didn’t sound like he quite disapproved of
this discovery, and that made Momo’s chest suddenly feel tight in the bra,
trying to catch a full breath from the exhilaration.
“Issei-san…” Momo cast a quick look to the door. The sound of the camera
shutter and the chatter of the set could still reach them, footsteps going back
and forth too.
Picking up on Momo’s worry, Issei said, “I locked the door after they left.
Although if you want me to stop, you better voice it. Or push me off. I’m your
prisoner here, right? I’m limited to what I can do, so you’ve got the power to
make me stop.”
The words first sounded odd coming from Issei, who never went along with little
plays like this, but that was when Momo realized he was trying to reassure him.
The gesture was enough for Momo to lose his breath as he shook his head.
“It’s okay.”
Issei kissed him again.
Moving took adjustment with his hands still bound, but Issei more than
compensated with the press of his lips and the sensual drag of his hot tongue
on Momo’s chest. The bra was pushed up, the soft fabric rubbing over his
hardening nipples then exposing them. Sucks, gentle then rougher, enveloped
them, sending shocks of pleasure down Momo’s sensitive body, pooling between
his legs.
He cried out, high-pitched, wriggling his hips and rubbing his legs against
Issei. Teeth bit lightly at his nipples and Momo jolted.
“You hate that?”
“N-no, j-just surprised… Ahh, y-you bit it…”
“Is sucking better?” Issei gazed up at Momo, returning his mouth down to his
chest, licking in a soothing gesture over his nipple. Momo couldn’t voice his
opinion either way, giving in to the waves of heat rolling down his skin. He
continued to squirm about, unsure what he was seeking exactly, but he arched.
Under his skirt, it felt like his panties didn’t fit him anymore either -
- tighter, his cock steadily hardening.
“H-hiih… Issei-san… Aah, it...it feels… It’s uncomfortable…”
“Hn?” Issei pulled back, stared at how Momo rubbed his thighs together, how his
small hands worked to try and smooth his skirt down that kept falling higher
and higher up his legs. Issei moved down Momo’s body, nudging into one of his
knees. “Keep your legs open,” he murmured, pressing a chaste kiss on his leg.
The rain of soothing kisses returned, reassuring the tremble in Momo’s legs as
Issei’s lips brushed up and down his thighs. He buried himself under the layers
of the frilly petticoat, hiking it up ever higher, exposing Momo more. Under
his skirt...was probably nothing girls Issei had no doubt gone out with before
had. He had the skirt, even the panties that Kokoro taught him how to wear, but
what he had there might not be something Issei wanted to touch.
But Issei kept kissing without hesitation, higher and higher, tingles tickling
the insides of his thighs. Then his breath was heating right between his legs,
right in front of…
Momo whined, in protest or impatience he wasn’t sure. His eyes had shut without
him knowing but when he opened them again, there under a fallen compact mirror
was--
“Issei-san!” Momo sat up, and Issei pulled back from under his skirt. He didn’t
look frustrated in the least at Momo’s outburst even though he didn’t know what
it was about, and instead backed up a bit to give Momo space.
Oh. He thinks I didn’t like it. B-but that’s not the case at all!  Quickly,
Momo reached over under the compact and showed off his prize. “I-- Momo found
the key! Issei-san can be free now!” Without waiting for an answer, Momo moved
behind him, fitting the key into the cuffs with a click, and at last, the
shackles fell from Issei’s wrists.
In retrospect, using real handcuffs was probably a mistake, but at least in the
end their predicament was over. Momo sighed in relief, halfway in asking Issei
if he was okay -- and then Issei had turned, pulling Momo close, his arms
capturing him completely in an embrace.
“Issei-san…”
It was silent, just Momo being held, relaxing into the hug that had come so
suddenly. Then, gradually, he relaxed, smiling as he giggled in his throat.
I wonder -- is it selfish for me to think that Issei-san really wanted to do
this the whole time he was handcuffed?
Issei was rubbing soothing circles at the small of Momo’s back. His neck and
collar were kissed and bitten lightly at. The sultry sensations before returned
in full, and Momo’s cock stirred again, still hard, nearly achingly so after
almost having been touched.
“U-unn… Issei-san,” he panted. “Feels...funny again…”
“Down there, right? Guess I should take responsibility.” Issei’s large hands
moved down from his back, smoothing over his skirt and then moving under it,
sifting through the frills to grab at Momo’s ass.
It took all of Momo’s willpower not to cry out in shock at the feeling of Issei
groping him, squeezing one of his buttcheeks through his panties. Instead, he
moaned in his throat in a low octave Kokoro would surely berate him for. But
Kokoro wasn’t there, and Momo’s mind was too hazy to correct his voice and
speech. He wondered if Issei would mind it, him saying “boku,” giving up the
higher pitch of his voice, letting him see and touch under his skirt; Issei did
still call him “Momosuke,” so maybe...
“Is it still good?”
Momo closed his eyes. “Mo-- I like it. Issei-san is so warm. I...really like
it.”
Issei breathed into his hair. “Good.” He shifted, just for a bit, long enough
for one hand to slowly pull down his panties, the other coming up to his mouth
and putting in three fingers. At first, Momo had no idea what it was for, but
Issei was feeling along the cleft of his ass, and he connected the dots. Even
he had a basic idea of how two men touched themselves.
“Ah… C-can I too? Issei-san’s fingers…”
Issei raised his brows, surprised, but he grinned at Momo’s boldness, slipping
his already slick fingers between Momo’s lips. The mix of Issei’s tastes, his
fingers curling against his tongue, Momo let out weak little moans as he gave a
tentative suck. The lewd sound of it stirred him up more, and his hands, not
knowing where to place themselves, settled at Issei’s belt, trying to undo it.
The fingers were pulled out of his mouth, slick with saliva. Issei used the
hand to feel under Momo’s skirt again.
“You’re bold today.”
“I-I was...just thinking how I want… It’s not fair if it’s just me, so…” He
didn’t even know if Issei was worked up like him. Maybe Issei wasn’t feeling
anything yet, while Momo was melting at his touches.
Uuuuu, I would die if Issei-san didn’t like this too … Momo shifted his hand
down, feeling the thick column of Issei’s cock in his pants, gradually
hardening at the same time a slick finger rubbed at his entrance.
“Hiih! Th-there is…”
“Keep going?”
Momo nodded, holding his hips in place. The press against his hole was foreign
to him, as was the first slide of Issei’s finger inside him. “Nngh!” Slowly, in
and out, Issei pumped his finger inside Momo.  Uwah… Really -- weird…  Not bad,
just strange.
Eventually, a second finger nudged its way inside, and Momo tensed at the added
intrusion. It was starting to hurt, especially as Issei probed in deeper with
both fingers. “Unngh… haa, I-Issei-san…” Momo struggled to distract himself,
remembering then his hands were grasping at Issei’s belt. He made short work of
unbuckling it and then undoing his fly with shaking hands.
Oh, its -- r-really --  huge , ah -- Momo’s own erection twitched again as both
his hands grasped at Issei’s cock, thick and hard and heavy against his palms.
Right here, is the hottest part I’ve touched on Issei-san … Uncertain, he tried
a few strokes, mirroring the rhythm Issei had built up with sliding his fingers
in and out of Momo.
Bit by bit, his body stopped offering resistance, although he couldn’t stop his
walls from squeezing around the intruding in him, forcing him open. Rather than
feeling discomfort, Momo started to press his hips back on Issei’s fingers.
“H-haaa, aah…”
“You’re getting used to it? And if I do this?” Issei’s fingers started to move,
curling and rubbing against Momo’s soft insides.
Momo cried out, hands squeezing at Issei’s cock. The shocks of pleasure
returned, flooding through his veins as Issei explored him, caressing spots
inside him that made Momo dizzy and hot. He buried his face against Issei’s
shoulder, moaning and completely at the mercy of the warm fingers inside him,
squelching lewdly as they moved about his hole, gradually going faster.
In his haze, he managed to keep moving his hands on Issei, pumping up and down.
With each breath, Issei surged in him deeper, Momo trembled more and squeezed
harder, stroking faster as if he were touching himself. His own cock was
neglected with touch, but still he felt the petticoat growing wet with the cum
no doubt dribbling out from his tip. Rubbing and nuzzling and whimpering,
ineffectively biting into Issei’s shoulder with his small jaws, there was just
too much at once, his body sending signals to move this way and that because
everything felt so  good  -- yet still, he searched for something  more .
With his free arm, Issei held Momo, petting through his hair, rubbing his back
and that felt good too, such a tender gesture.  Ahh, I knew it, I knew if it
was Issei-san then this wouldn’t be scary, he would never let me fall --
Then Issei hit  something  inside him, and Momo didn’t know  what , only that
the pleasure whipped him into a frozen state, a broken scream muffled into
Issei’s shoulder as his cum spilled out without notice, slicking up his thighs
and surely staining the petticoat.
It was only with the slight voice in his head nudging him to some semblance of
coherency that he continued to touch Issei too, frantic and desperate until
Issei cursed low in his throat and came too, staining Momo’s hands. Momo pulled
back slightly, curious more than anything at the sight of the thick white mess
oozing on his fingers.
“Ahh… Oh no, we ruined the costumes…”
“Shit.” Issei seemed to have realized it himself. He sighed, petting Momo again
and sliding his fingers out from his entrance, not without Momo blushing and
relaxing after contracting his walls tightly on Issei’s fingers when he came.
Issei got up, searching the room for tissues and coming back to clean
themselves. Not much had gotten on his clothes, but dabbing at the lace of
Momo’s petticoat took some work. Some more tissues and hand sanitizer in
Kokoro’s bag helped clean the mess from their hands. Momo slipped his panties
back on and fixed his top while Issei buckled himself back in. Since the key
had been found and Issei was no longer trapped in handcuffs, they should
probably get back on set, right?
But as Momo fixed his hair trying to keep himself busy, he finally sighed.
Maybe the rush hadn’t completely left his body because he felt confident enough
to say, “Do we have to go back to the shoot? Runa-chan said we were done. And
I’m sleepy suddenly…” He knew he sounded childish, but curling up next to Issei
sounded like heaven right then.
Luckily, Issei didn’t seem to mind, and only petted Momo’s head. “That was the
first time you got touched like that, huh.” He smirked. “You even managed to
finish without me touching you from the front. Youth is like that, huh? Heh.”
"Uuuu, you sound like Futami-san."
"Haah? Don't compare me to that guy." Issei picked up the handcuffs and keys
from the floor, holding them out. "Oi, don't lose these again, got it? I don't
plan on being handcuffed like that again."
Momo laughed self-consciously, but nodded. Well, in the end, they went with the
flow of the situation and it ended in this way. Momo couldn't say he was
unhappy about that, not when he'd been that close to Issei.
It was all an act for the shoot, but Momo knew long ago already that Issei
Todoroki had captured his heart.
End Notes
     This was really fun to write and I just love the idea of Issei being
     super gentle but teasing when he and Momo get intimate.
     Hit me up if you'd like to have a commission done too!
