Chapter 7

Natsu's POV

"Luce, I love you." I tell her again, I need to kiss her but just as I'm about to reach her she pulls away raking hey fingers up and down my front. I can't help moaning as she does though, especially when she starts kissing the light scratch marks that she left behind. 

What have I done? I can barely think as I look down to see her eyeing my shaft. What is she? I can barely think the words before she looks up and smiles grabs me hard and oh so very slowly licks the tip. I can't help spasming under her touch thrusting my hips into the air, my body practically begging for more of these weird feelings. 

How does she know how to do all this? Why didn't I know that mating could feel like this? 

"Natsu," I open my eyes at the sound of her voice seemed to caress my name. "Don't look away. You should watch all of this." She purred as she licked from the base to the tip this time. 

"How?" Is all I can manage before she puts the entire head in her mouth. I pull on my scarf wishing I could grab ahold of her and push further in. 

After what felt like forever and yet not nearly long enough she stopped bobbing her head and pulled away. I watched as she licked up what I could only guess was her own spit until she squeezed and pushed out what I can only see as a drop coming out of me. She licked it up and smiling at me she started doing it again. 

I know I didn't cum yet. Just because I haven't had sex before doesn't mean I haven't masterbated before. Whatever Luce is doing to me is equally a blessing and a curse. I can feel myself building up and I needed it to be inside of her. As amazing as her mouth feels, that's not where I need to cum. 

I feel her sucking now and kissing as she went. "Luce!" I beg her. 

She looks up and smiles, "I have waited a long time for this and I want it to last. Please?" she purrs the words as if I had any real choice. 

I swallow dryly, "I can't last too much longer." I lick my lips as she swirls her tongue around making my eyes roll back. 

"I kind of want you to cum on my breast before... You know." She whispered shyly as she now gripped my balls in her hands making my hips thrust into the air again. How can she act so shy while doing all of these things? I wanted to scream in frustration.

"What? But..." I say and she practically swallowed me; her lips went all the way to the base. I was seeing stars as I moan out her name. "Lllluuuuuucccceee!" I still haven't cum yet. Damn it all, just how? 

I look down to see she has one of her hands still holding me tightly as she now licked up and down my shaft again. Was she blocking it? I pull on my scarf again. Why did she have to tie me up?

"Fine, I'll cum anywhere you want just please!" I cry out in a strained whisper. She smiled and finally came up to kiss me again. I don't know how long we were kissing but I was well out of breath when she pulled away. 

"Let's go to the shower," she purred as my head swam trying to make sense of all of this. I followed her and she took a seat by the shower pulling me closer to her. I don't know how she managed it but I still had my hands tied together just not to the bed anymore. She took me in her mouth sucking so hard I could see the stars and just when I thought I couldn't take anymore she pulled me out of her mouth and released my shaft. 

I came on her mouth, her neck and her chest. It wasn't a small amount either. She had thick creamy white fluid drizzled all over her and when I thought I was going to collapse I saw her licking her lips and rubbing my cum smoothly on herself. 

I thought she was the most amazing woman before but now I know there isn't anything I wouldn't do for her. I watched as her hands slid across her chest and when it looked like it had been pretty much rubbed in she started licking her fingers. My cum was all over her, I could see the creamy fluid running down her body and it was the sexiest I have ever seen her. 

"Luce?" I whispered only barely hoping we weren't done yet as my dick never got the chance to soften before hardening again. I could feel myself throbbing as I watched her grab me again and put me in her mouth again going all the way down once before pulling away again. 

"We aren't done yet. No where close." her voice sounded like velvet as she purred the words. What have I gotten myself into?

Lucy's POV

"We aren't done yet. No where close." I purred to him. I can't believe I did all of that! I am still wet from his cum and my own juices are practically flowing out of me. I can feel it dripping down my legs. I just want this to last forever and it looks like Natsu is all for it; he is rock hard and if it's possible it looks like he is ready to cum again now. 

I can't help the smirk on my face as I see his eyes roll back into his head again before I released him with a loud pop. "Do you like the view?" I ask him getting a few quick nods and heavy panting for an answer. "Would you like to try?" I ask him leaning back in my seat resting my head against the shower wall behind me. 

This seemed to snap him into focus as he looked down at me. I widened my legs so he could see my now very wet pussy waiting for him. I saw his eyes widen but not until I saw him inhale deeply. Smell was the ticket huh? I can't help thinking about the bottle of pheromone shampoo I bought on our last mission. I still haven't opened it yet. 

He sank to his knees as if he were in a daze and I let his arms go around my neck and passed my shoulders down towards my hips still tied together as he lifted my hips towards him. I could hear him inhaling my scent and his eyes looked glazed as he finally licked along the outer lips shooting pleasure through me like electricity. 

I reach over and start the water for the tub, Natsu doesn't seem to notice exploring this new part of my body. His tongue was so hot I should have been wondering how he wasn't burning me but no. I could only moan and gasp as he got either more confident or excited by my taste and smell, going deeper and swirling it around. It didn't take him long to realise that if he licked and sucked on my clit just right more of the substance came spilling out of me. 

"Nnnnaaaaatssssssuuuuu!" I screamed his name as my body convulsed against his mouth. He was looking up at me no longer dazed his eyes razor sharp taking in every little response to whatever touch or movement he did. I came hard but I was nowhere close to done and from the looks of his throbbing shaft he wasn't either. I pulled him up and put a hand on the knot tying his hands together. 

"Are you ready?" I asked him almost breathless as I kissed him. 

"Luce, I've been waiting a really long time now." He hissed as he leaned in to kiss my neck. "You have to go first." He nibbled on my neck shooting more pleasure through me. 

I bite him, hard and I kiss and suck until I start to taste something spicy but sweet. I look down and see that it was his blood he has a smallest nick and I kissed and sucked on it until it stopped bleeding. I could feel Natsu's member pressed against my opening hard. I glance around and see the clean tub of water completely forgotten from earlier. "Natsu?" I breathe pointing at it before untying his hands.

"You want our first time in the bath?" he asked before smiling. He reached over and dipped a hand into what I'm sure are now icy cold waters. 

He picked me up and laid me down in the now hot steamy water earning another gasp from me. "Natsu," I moaned his name as he situated himself between my legs. 

"Did you get blood?" he asked now kissing on my breast making loud sucking noises. 

"Yes," I responded, waiting to feel pain but instead I only felt pleasure as he moved up my neck kissing, sucking and biting me in ways I never could have dreamed of. 

"Are you ready?" he growled in my ear setting my heart racing again. 

"Yes!" I felt his teeth scraped along my neck making me moan more and when I was to the point I couldn't do much but pant is when I felt a small pinch on my neck. The pain was gone before I could even register that it was ever there, because at the same time he lined himself up and pushed into me. 

My back arched at the welcome intruder almost like it was trying to help pull him in. My breathing had all but stopped and was now ragged as he slowly pushed himself in, careful not to hurt me. "Natsu!" I couldn't do more than breathe his name but I know he heard me when he froze. "More, please. So slow, deeper, faster." My words barely made sense to me so I don't know how he understood me. 

My breath caught as he pushed the rest of the way in, filling me. It took a moment for me to adjust to him but when I did I couldn't stay still. I needed him more now than ever before. 

He moved with me gently, slowly and when he finally released my neck he kissed me. These sensations are so new to me and yet so much more. I held onto Natsu as if he might disappear any second now. I tried so hard to memorize his taste but it never seemed to be enough so I would kiss him deeper. 

Then when it felt like I couldn't take anymore I screamed out his name, "Natsu!" I felt like I was about to break as I tried so desperately to hold onto him, to pull him in closer. My world was shattering and all I could do was scream in pleasure as I felt him stiffen inside of me and his moans joined my own. We collapsed into each other as we hit our release, finally we were done. 

Natsu's POV

I can feel myself slowly going soft even while still inside of her. Never have I felt anything so amazing as sex before. I feel like my world has shattered and I am perfectly okay with that. 

The water seems to have slowly evaporated while we were distracted. The bathroom was full of steam and the tub only had a couple of inches of water left. I reach over and turn on the water making sure it was cool enough for Luce. When it gets comfortably full again I snuggle into her again having turned the water back off. 

"My mate." I whispered as I cuddled her. 

She starts to stir and grabs onto me again. "Again?" she asked as if she were afraid I would say no. 

I can't help smiling and pulling her in for a deep kiss. I could feel myself hardening and I pull ever so slightly out before thrusting in again. We ended up climaxing another five times and refilling the water once more after the fifth. 

I watch Luce as her breathing relaxes again, unsure if she wants more or if she is about to pass out. I feel her arms tighten around me. "One more time and then bed," she yawns kissing on my neck close to where she bit me. 

"Aye sir," I whisper filling her again. It isn't too long before we finish and again the water seems to have disappeared. I just shrug it off as I pick up my mate who seems to be barely awake and carry her to the bed. "I love you Luce." I whisper kissing her on the head wrapping my arms around her under the blankets. I feel sleep start to steal over me when suddenly I wasn't tired anymore. I was painfully awake and turned on again. I groan feeling her body pressed against mine. 

"Natsu?" she yawned turning back towards me. While she was turning over she somehow managed to hit my dick, thankfully gently but it didn't stop me from jumping. 

I look at her to find her wide awake now and with what can only be described as pure excitement written on her face. "I thought you were tired?"she teased me. 

"I don't know what happened, Luce. I swear I was about to pass out and the next moment, well this." I tried to defend myself. 

She clicked her tongue at me in disapproval. "I'm your mate now right?" she asked, smirking. I gulped and nodded in answer. "Good then," she got on her hands and knees again crawling down my body. "This is mine." She whispered and took my now throbbing shaft in her mouth again. 

Lucy's POV

It's been a good three or four days since we went to the guild. I don't think either of us slept a wink everytime he would get close to collapsing he would somehow get another rush of energy and we would start all over again. I have found that biting his neck where his mark is now gives him or myself a burst of pleasure. Our marks look like stars on our necks and I love that they are identical. 

I think we have been awake too long and I don't know how I have been keeping up with Natsu. Unlike him I am just ready to keep going and going but I also know that we need to rest. I have never been awake this long doing anything and here I am ready for another marathon. I get up to grab us a glass of water just to have Natsu grab my arm again. 

"Luce?" He looks like he is in pain. I crawl back on top of him and sit down on his now pulsing member again. I can't help the gasp that escapes me as I do. Like everything in the world is okay again. When he cums this time I don't pull away. I know he needs to sleep and soon.  Maybe if I keep him inside he can finally relax enough to fall asleep?

I can feel myself growing more and more frustrated as I lay there combing his hair with my fingers when his eyes snap open again. Well that didn't work. I smile, oh well it's not like I can't keep going. All the books I read did not prepare me for this hunger. I couldn't seem to stop. I would finish with him every time and they were all amazing. But then just a few seconds later I was ready to go again. Almost humping him at some points, the days passed in this very strange yet wonderful way.

Suddenly I hear clapping and look around the room keeping myself above the now passed out Natsu. "Who's there?" I demand as I pick up my keys from the bedside table. Out of reflex I felt Loke's key slip into my hand. But almost as quickly I felt my magic resonate within me and I relaxed again. 

"If you want to make a contract with me can you give me a minute to get dressed?" I ask the unseen visitors. 

"We much prefer you naked and fully sated." I heard a female voice respond. 

"We?" I ask again remaining where I was. It wasn't much but the blankets at least had where Natsu and I were connected together covered. I tried in vain to cover my chest from the unwelcome eyes. 

"Yes, we are the duel sin keys Lust and Envy." I hear a deep man's voice respond this time. "I am Incubus my sin is envy," a very handsome man with black leathery wings revealed not only himself but another dark and beautiful woman with matching black leathery wings next to him. 

"And I am Succubus my sin is lust," the female slightly bowed her head to me. "I must say I am impressed. Most humans that get my blessing only last about two days. Not you, though. I wonder if it's because you were so horny for so long before?" she said her voice was velvety smooth and seemed to slide right down my body in pleasure. 

"Incubus and Succubus?" I ask to make sure I have them correct. 

"Yes, but you may call us something else if you wish?" Incubus asked me. 

I shook my head no, "I will not ignore your names. They are a part of who you are." That seemed to be funny to them because they both laughed quite a bit. "What do you mean by blessing?" I asked looking at Succubus again.

"Well anytime I consider giving my key to someone I give them my blessing first. To see if they are worthy to be the holder of lust." she paused and waited for me to motion for her to continue. "It's a test that lasts for four days and no one has ever made it to day three." she looked up at me again. "Until now that is, you didn't only meet my four day challenge you broke it. Eight days! You have been locked up in either your bed or bath tub for eight days feeding into your desires."

"It was getting to be too hard to re energize your lover so we decided to end your test especially after seeing you try to let him rest so many times only to fail and well. Pleasure him again." Incubus moaned from where he was next to Succubus. 

"Duel keys?" I asked instead, trying to ignore the rush of need flowing through my body as I felt myself clench onto Natsu. Thankfully it provided some relief even if only a little. 

"Oh yes, you cannot hold one without the other. We are the duel keys because it is a double edged sword. If you agree to make a contract with us you will be afflicted with our sins. Although I bet Griffin the sin of pride neglected to mention that." Succubus purred sliding a loving arm down Incubus' arm nearest her. 

"I did not know that," I looked up at her after a moment of thinking. "So if I make a contract with you two I will be horny all the time and constantly accusing Natsu of cheating on me?' I ask them. 

They laughed for a few seconds before answering. "You are half right. The sin of lust will make you horny a good bit more but no we do not change your very nature. Besides, everyone knows that dragons only mate with their life mate." Succubus explained. 

"Having said that you will probably become a little protective and maybe a hair possessive of him around others. Only marginally compared to what you normally are though so no one will likely notice." Incubus explained further. 

"I see," I nod slightly before looking back up at them. "So did you want to make a contract with me?" I ask them again. 

"Our only requirement is that you must call us out together anytime you need one of us you must call both of us." Succubus replied. She and Incubus hold out their keys for me to take. 

"Deal." I felt a rush of magic fill me and before they went to the celestial realm they turned back to face me one more time. 

"By the way if you use envy you can give your lover some of your energy and it will help to relax yourself as well." Incubus smiled at me. 

"And if you use lust you will be able to excite him or whoever as well. Not that a dragon needs much temptation" Succubus added, winking as she did.

I nod my thanks, "I should let him sleep. He has been through enough as it is."

"If you don't finish yourself you will cause not only yourself but him pain in the future. If you share your energy he will only be better for it. There will be no lasting side effects either good nor bad." Succubus advised. I nodded my head in understanding and they disappeared into smoke. I put their keys by Griffon's with Plu's key in between them just in case.
