Kinktober 2021, 24: Marking/Possession
(Reader x Munehisa Iwai | Persona 5)

You had been on your way to visit Iwai at his shop that evening, knowing it wouldn’t be quiteclosing hours by the time you arrived, but at least it was sure to be slower than peak daytime hours. It had been several day of meaning to visit and having something come up that kept you away, but you’d finally been able to make time.

You hadn’t intended to be recognized by an old school friend and stopped in the street just past the turn in the alleyway. Deciding a few minutes wouldn’t hurt, you were happy to talk for a little bit, promising yourself you wouldn’t let it go on too long.

The conversation went on long enough to exchange pleasantries and ask a few simple questions about what each of you had been up to since you’d last met, and how you were doing then. After a couple of minutes longer, you decided you’d spoken long enough, and needed to be going, informing your friend you had to get going or risk being late. He seemed a little disappointed, but didn’t protest.

They prompted you for a hug goodbye, which you kept short and casual, before they headed off, both of you giving a wave. Having turned away from the direction of the shop while you spoke, you turned back to face the window not far off. You hadn’t considered Iwai might have been able to see you through the glass from where you’d stood, though even if you had, you wouldn’t have thought any of it. You had only been speaking with a friend, after all, nothing wrong in your mind.

Iwai, though, watching from behind the counter in his usual chair, thought otherwise. Though to him, it hadn’t looked merely ‘friendly; not on your friend’s part at least. Your back had faced him, giving him a plenty good view of the man’s face. There was familiarity in his expression, sure enough, but something wanting as well - something that hadn’t occurred to you at all. To Iwai, the hug had lingered far too long, and looked much closer from the angle.

Ordinarily, Iwai wouldn’t have thought himself a very jealous man, but something about that moment had rubbed him the wrong way, and set off a chain of rather possessive feelings. As he had watched the encounter, he had felt irritable, biting down on the lollipop in his mouth unconsciously and causing it to crack.

Your mood as you entered Untouchable was bright and excited. The quick reuniting with the friend from before had been nice, but it only added to the excitement you had to see Iwai again. You were nearly beaming when your gaze met Iwai’s, unable to read his current mood beneath his usual facade of grumpy indifference.

“Sorry for being a little later than I promised. Ran into a friend I hadn’t seen in a while,” you apologized cheerily.

“Yeah, I saw,” Iwai griped gruffly, sitting back in his chair. “He sure seemed a lot happier to see you than you think..”

“Happier to see me than I thought?” You repeated, confusion dawning on your face. It hit you suddenly that Iwai hadbeen able to see you, and he’d mistaken what he’d seen. “Oh! Oh no, you’ve got things all wrong. It’s nothing like that, he’s just a friend,” you assured him.

“Yeah, sure, and that little hug was just plain and friendly, huh?” he growled, standing.

That strange accusation confused you even more. “Listen, there’s nothing you need to worry about. What’s gotten into?” you asked, unable to stop the cross hint that crept into your tone.

Iwai strode around the counter as you took a step closer, before passing you to head to the shop door. He drew a set of vertical shades down over the windows, effectively blocking them out, and locked the door.

“What’s gotten into me is I don’t like how he was lookin’ at you. Not to mention how you seem okay with it,” Iwai said as he turned from the door to face you.

“Iwai, you’re not jealous of some friend I haven’t seen in years, are you?” you questioned skeptically. You hadn’t missed what he had done, and you had to wonder what was going on in that head of his.

Iwai made an irritable huff, though didn’t speak for a moment. He walked back toward, and you backed up to keep a bit of space between you, until there was no space left and your backside pressed against one of the display cases.

“Jealous, huh? Maybe I am,” he ground out as if the thought were both aggravating and amusing.

Iwai stopped, placing both palms on the counter behind you, and you heard the clack of hard candy against his teeth. You waited silently for Iwai to continue, realizing you had unintentionally been holding your breath, though you weren’t quite sure what over.

“Think I’ll do something about that,” he decided, the irritability fading from his rough voice.

Again, you were puzzled, wishing you could better suss out his thoughts. What exactly did he mean? And why did wondering what he meant make you feel almost excited? “What’s that?” you asked curiously.

Iwai didn’t answer, taking a moment to pull the stick of candy from his mouth and set it aside. He leaned in even closer, cupping the back of your head, using his hold to direct you. He kissed you roughly, though even still his lips were warm and welcoming, despite the force behind them. He took a moment to practically devour your lips, leaving you pleasantly dazed and a little breathless.

He broke away for an instant, only to return quickly for another kiss that made you feel hot all over. His tongue thrust demandingly against your lips, and you needed little convincing to let him in, swept up in whatever it was Iwai intended to do to assuage his supposed jealously. His tongue tangled with yours, leading but not entirely dominating it.

When Iwai stopped again, you took a deep breath, both to recover from the breathless state the whole make-out had set upon you, and to soothe the smoldering heat building in you. But Iwai wasn’t done, his goal not simply to kiss you so fiercely you couldn’t be bothered to think any anyoneelse. No, that wasn’t nearly enough.

His lips attacked your neck next, the stubble on his chin rasping against your skin, a complement and contrast to the touch of his lips and prick of his teeth. He moved down, mouthing at your throat and your collarbone where it peeked from your shirt. You could do little but hang onto him with one hand around his shoulders, the other pressed to the glass behind, enjoying the sensations, the confrontation from before forgotten.

Iwai’s ground his hips slowly against yours, pressing you between him and the case more firmly. You moaned low, moving back against him as best you could while so effectively pinned. It was easy to feel the thick, growing bulge in his jeans, and another wave of lusty excitement washed over you, and you clung to him tighter.

After a little while kissing and biting your skin, and grinding torment against you, Iwai pulled back, wrapping his hands around your thighs. He lifted you off your feet before settling you on top of the counter, rather than against it. He released your thighs only long enough to fuss with the waistband of your pants, pulling down and discarding them and your panties. Next came the fastenings of his jeans and his underwear until his dick stood eagerly between you.

His hands returned to your thighs, urging your legs around his waist and pulling forward over the countertop. He pressed his face into the hollow of your throat again as he lined his cock up with your entrance. You heard him groan when he pressed half-inside of you with a rough buck of his hips, A sound that was half hiss, half moan poured from lips, wet, but not quite wet enough that there wasn’t a bit of a sting behind the stretch of your walls. The rest of Iwai’s entrance was a bit slower, a steady ease of his hips forward until he was enveloped completely.

The tease of his teeth and the clothed grinding had lent more to the sparks of desire and heat, and you clung to Iwai again, making a needy sound as your cunt squeezed him. Iwai set a smooth, hard pace quickly, repeatedly rocking into you and making you moan and gasp and dig your fingernails into his back. You thrust back, searching for the perfect friction until you found it at last and your voice grew louder and more obscene.

Iwai kissed you hotly again, swallowing the lewd chorus leaving your lips and drowning several gravelly groans and grunts of his own. His hands had returned to your body, gripping the swell of your ass to press deeper into you with each thrust. The new kiss was sloppy, but intoxicating, adding to the building sensation of liquid hot tension in your gut the promised bliss. You squeezed your legs tighter around Iwai’s waist, nearly trembling with the mounting intensity.

When you came, Iwai broke apart from your lips once more, and your lewd cries filled the room again, along with several shouts of his name. Your back arched and your head dropped back, one of Iwai’s hands moving up to spread across your back. Iwai cursed softly but continued to thrust through the fluttering of your walls.

He withdrew suddenly, and you shuddered, whimpering at the loss and the sudden emptiness. Iwai’s hand fell away from your back, shifting to his cock and stroking desperately, all the while his breathing grew heavy and sharp.

“I’m gonna - fuck - make sure everyone can see you’ve already got somebody,” he groaned, pumping himself even more vigorously.

Several more pumps of his fist and Iwai stiffened, a long, broken growl of a groan issuing from his lips as his came in thick jets across your abdomen and thighs. Some of his cum spread across your skin, though much of it instead splattered across your shirt, leaving what would surely be a very noticeable stain.

“Shit, Iwai,” you admonished him breathlessly. “Do you know how much of a pain that’s going to be to get out?” You were still caught up in the afterglow of your orgasm, the idea of the stain irritating, but the motivations behind it somehow arousing as well.

Iwai laughed, sounding just as winded.

“You don’t say?”
