A/N

SO THIS ONE TIME MY BROTHER LEFT ME ALONE FOR HALF AN HOUR WITHOUT MUSIC AND THIS IDEA HAPPENED
We'd locked ourselves out and he was getting a spare key from our aunt nearby. Meanwhile I stood cold and wet from the rain inside a supermarket near closing time. So naturally I thought up this. My suffering bore a beautifully strange fruit.
Ah~ how very poetic of me.

**Warning beforehand; although the main focus is on the psychological aspect in this fic, it does contain its rare amounts of explicit sex scenes and violence. I have a warning in the author's notes stating every time it will happen next chapter**

Anyway, I'm treating you by starting with a flashforward, 'cos it's gonna take a while to get to this moment. If you don't want to start off with a sex scene, you can skip to the non-italics at the end, which are the present time.

Enjoy the entire ride, darlings ~

Psycho Love

'Come here.' I gestured for the boy to step closer. Just a couple of seconds ago, he'd blatantly said he took a liking to me – I'd expected something more subtle than that. Even when I'd just stared at him for a while and told him he was being unreasonable because acting upon something like this would put my profession at risk, he'd still stood there with a determined look on his face. Where this certainty had come from was a mystery to me – I thought it had disappeared this morning.

This 14 year old boy is determined to play the upper hand on me. I need to make sure he doesn't get that.

With all the confidence that he'd demanded for me to do this with him, he took careful steps towards me. I sat up and shuffled to the edge of the large chair and waited for him to get close enough. I never broke eye contact, and I could feel he was starting to get bashful under it again, even though he was doing a good job in hiding it. Moving this session to his house for one time had been too great of a risk, and I should not have refused my supervisor to come along. For a while now, Killua has been trying to prepare himself for this - he was determined to remove me from his case again. Being in his domain when saying these things, had certainly given him an edge. I now have to have trust that all the surveillance in this room has been taken care of.

'For someone so confident in confessing to me, you're taking your time. Have I not responded to your expectations?' He scowled when I actually said it.

'It's hard even having expectations of you, your jobs kinda make you unreadable.' I raised my brow a little. He had a point there, but I wouldn't let his reason get in the way. He's out to frame me again, I need to nip it in the bud.

'I'm putting my work on the line, I would appreciate it if you stopped hesitating.' He increased his pace a little until he stood right in front of me, in between my legs. I looked up at those big eyes, and sighed inwardly when I thought about the calculated risks. 'What do you want me to do?' He scoffed at me when I actually asked him.

'Don't have any ideas of your own?' I inclined my head slightly and decided to just do this so it would be over and done with. By now I've learned this white haired boy has too many reasons not to back down unless the situation is treated. Even if I'd be taken off this case, I would not be left alone. If I want him and his family off my back, I need to let them think they're winning the game.

So I lifted my hands, and very lightly stroke my fingertips up his upper legs, over his hips and landed on his waist with my palms. The look in his eyes had changed. For the first time since he'd started this game, there was genuine doubt. He hasn't done anything sexual before, he's most probably underestimated the effects of it on his mind.

His head is probably full of it by now in order to succeed today, but the expectations he's put on himself because of his genius reputation were way too high.

I refrained from commenting on any of this though, and slowly trailed my gaze down from his face, over his chest, and lowered my hands to his hips when I closed my head in on his lower abs. I hovered there for a second – feeling the tension in his body – before kissing the clothed area.

'…' A slight huff escaped his lips, and I released the pressure before applying it more firmly on a spot next to it. I pinched him while alternating in pressure and location, before making it clear where I was going. I could hear from his breaths that he was trying to pace himself in his excitement, but he seemed to be utterly failing. He really hadn't expected it to have this kind of effect, did he.

Although that he was reacting to it so strongly most probably meant he did feel some kind of attraction.

I stopped just short of kissing all the way down before flipping my hair and looking back up at him. He looked completely flushed, and was unable to look me back in the eyes. Confrontation.

'I believe this is the area that's causing all these problems, isn't it?' I let one of my hands glide away from his small hips to his groin, and he twitched when I touched it. He closed his eyes and bit his lip in embarrassment. His bark was greater than his bite at this point. 'It seems it's reacting quite well.' I trailed my fingers over it some more, making him lift his hand so he could bite on the back of it – opening his eyes again and forcing himself to look back down at me. He was angry at me for playing around it this much, and most probably angry that his body was responding so readily.

'Let's take care of that and continue with the session.' My hand slid back to its original position, and I moved my lips over his groin, letting my warm breath protrude the cloth and getting a restrained reaction from him.

'Aah…' I flicked out my tongue, and trailed the contours of his growing arousal. I paid extra attention to the tip and sincerely hoped that surveillance had indeed been taken care of with the sounds he was starting to make. If it wasn't, then I still had work to do afterwards. He lifted his hands, and laid them on my shoulders. Restlessly grabbing and releasing my shirt.

I moved my hands back some more, and massaged the flesh of his cheeks. There wasn't even direct contact needed, this boy would come within a couple of minutes if I'd keep this up.

But that would only confront him halfway, I need to put a stop to him coming after me completely.

Almost in slow-motion, I pulled my mouth away from him, and slid my hands down, looking back up at him. I waited until he was ready to make eye contact again. His face had turned a bright red, I don't think he'd expected to be this overtaken by touch – touch by me, no less.

'Come here.' He stepped back when I closed my legs, and gestured for him to come and sit on top of me. He was heaving slightly, but didn't refuse the command. He sat up on his knees with his legs on either side of me, and laid his hands around my shoulders. It felt obvious he'd started this with half preparation.

His face had closed in considerably, but I refused to kiss him on the lips at this point. That would show too much intimacy in a situation where I need to have the upper hand. He was expecting it, but I refrained from doing it and opted to trail my tongue along his neck to his ear, kissing him just below it.

He pressed his body closer against me in response, but I stopped him from doing that too much. I lifted my hands and started opening his belt and zipper. As soon as I started this, he clenched his arms around my shoulders tightly, making it almost impossible for me to keep kissing his neck. I trailed my fingers along the hem of his pants and underwear, and slowly pulled them down when I'd reached the side.

'I do need air in my lungs.' I whispered against his skin when his grip had relocated to around my neck. He shakily moved them, before I lay my head against the side of his and I reached up to his erection. He almost bit into my ear when he gasped at the touch. He's probably done this a million times himself, but there's really no comparing to when someone else does it for you.

'You don't need to hold back.' As soon as I started moving my hand, I don't think his body left him any other choice. He arched his back into the feeling and breathed out hard against my skin. After that, he kept his body still for a long time when I started pumping him. It wasn't until he was getting closer that he started moving his body in rhythm with my hand – his heart was pumping out of his chest.

I placed my lips against his skin again and wanted to pick up the pace to finish all of this, but for the first time during any of our sessions these last two weeks, he surprised me.

My eyes shot wide open when I gasped to the feeling of his hand that had snaked down and found its way to my crotch. My movements stopped for a second, thinking he had finally found the focus to make it backfire on me. But that wasn't even needed at this point, if there was surveillance, just me touching him was enough. I can't actually say that him being selfless is what's happening right now though, he's probably just being spiteful.

I didn't have the luxury of getting caught up in it though, and I started up again, ignoring the feeling in the lower half of my body. I pumped him until he couldn't focus on anything else anymore, and the movements of his hand stopped. He grunted out a bit harder and I felt his body hitch just before he let himself go completely. I covered his tip with my hand to keep it away from my clothes and refrained from doing anything 'till he'd rode it out.

Partly choice, partly because his hand had clenched a bit too hard in my crotch when he'd come. I closed my mouth shut to keep from reacting to that, but it hurt nonetheless. I was thankful for his releasing grip together with his breath evening out as well.

'Can you stand up?' I asked when the grip around my neck finally loosened as well. He lifted his leg off me, and I stood up from the chair, walking towards the bathroom to clean myself up. For as far as I heard, Killua hadn't moved away from the chair.

This is bad… I opened a cabinet to get some tissues first to clean off my hands. He'd actually wanted it, or had put on a better play than I'd expected. The bad thing though, had started the moment he started touching me as well. Although subdued by his unsubtle release, I had gotten excited…

'Illumi? How did your session go?' I got shook out of my focus for a second when Zeno addressed me. I'd been staring into space for a while, organizing the cases he'd put me on before in my mind. He's been putting a lot of work on me lately. Normally that would look like a sign of trust, but it didn't feel that way. It felt like he was playing at something. I just don't know what it is yet.

'Not a problem at all.' I answered a second later. He was referring to my most recent case where the patient had just been transferred to another, by the way. It wasn't that I'd been doing badly, it was that it had nothing to do with my field anymore. I looked up at him when he went to stand beside me and stare out the window. It was mid-winter and the snow was blowing across the parking lot in a thin layer. I was hoping I wouldn't get snowed in again. This place isn't built to be a hotel.

'Good, I hear promising things from the feedback as well. Do you feel up for another case?' The old man wanted to put me on another case of his?

'Will I be supervised this time?' I looked back out the window again as well. Oftentimes I would be left alone in this even though most times we worked in pairs. I'd get milder cases and I had no problem dealing with that, but I feel like I can learn more if I would be given more of a challenge. I don't like stagnation.

'With this case you are.'

'What's the case?'

'It's a violent 14 year old boy from the Zoldyck family, Killua. He had come close to his first murder two months ago. Although judging from his reports he's probably succeeded before.' Zoldyck? That's not a small name. But not only that,

'That's a level higher than you usually ask me for.' What is he testing me for?

'I don't think it's above your capabilities. You'll be working together with Dr. Lucilfer.' I had no problems with that. Chrollo Lucilfer is a composed man, and given the opportunity I believe I can learn a lot from him. 'Don't sell yourself short.' He looked back down on me and I returned the attention. 'You're better than you think, I believe you could work on equal footing with him.' A compliment like that from you?

'I don't like flattery of this kind, but I'll be happy to accept the case.' He huffed at my response before walking away. I followed him with my eyes for a second before leaning back in my chair. I know I can most probably get along with Dr. Lucilfer on a lot of areas, but there's something different about him, about the way he handles things; and there's not an employee in this entire institution that would pass up this opportunity.

Still…

A fourteen year old boy from the Zoldyck family having been caught wanting to commit a murder. With their reputation I didn't think they'd ever get in a situation like this. I need to start reading up on this Killua.

A/N 2

I'll be switching POV's between Illumi and Killua from now on. Please tell me if it's unclear when I switch, I'd hate for such lack of clarity to keep you from understanding what's going on.

It's gonna be more of a psychological fic, I'm really really filled up on sex because of "Will you Illuminate me" so I'm returning to my roots, so to say.

R&R and I will love you forever *bows politely*
