A/N: I decided that since the length of my chapters is inexcusable, I would post two a day. That means I need to start writing more, but I don't want to keep you guys in suspense! Please R&R, flames will be laughed at, constructive criticism taken into account. Thank you for reading!

Chapter 2: Substitution

I rock into you and imagine it's him instead. Your ankles dangle over my shoulders as you moan underneath my heavy breathing. Sweat glistens all over my young, finely toned body. You look up at me, lust emanating in almost waves, begging me to touch you. I delicately trace your slit and run my nail under the seam of the head. You hiss in pain and pleasure. The smile and flash in my eyes make yours widen in trepidation. You still have bruises from the last time I went black during sex. But it has been so long since I've had you, I can't hold back...

The change is instantaneous. I squeeze the shaft of your cock in my hand, disregarding how much pain you are probably experiencing. All I know is that you arch up into my hand and I take that as a good sign. You writhe on the sheets, agony and bliss wrapped together. You are the only one,...the only one I enjoy while I am in black mode.

Suddenly, I exit you and grab you by your hair. You submit and let me take control, despite the fact that you are several years my elder. I kiss you hard, biting your lip, and the force my thrashing tongue in to your mouth so deep, so hard...I nip and nibble, bruises inevitably marring your milky flesh, sometimes I even draw blood and lap it up. Next thing I realize, I have flipped you over onto your belly and have one of your arms twisted behind your back. I am thrusting my cock into you from behind and you are futilely trying to support yourself with the shoulder of your restrained arm and your other hand is pressed against the wall to stop your head from going through it. My hand is occupied with the job of beating you off.

The room starts to grow hazy with white fire, burning everything in sight. My eyelids shudder and my body quivers with release as I reach my climax. We simultaneously let out moans of ecstasy as our seed stains your sheets and our already slick bodies. I collapse onto your back, letting out a sigh as my arms fall and hang on either side of you. You roll over onto your back and I snuggle up on your belly, having already reverted back into my white form, trying to recover my breath and reach a normal breathing pattern.

"I'm' sorry...I tried to stop, but I couldn't help it. I tried not to switch,...really, I did. I just-"

"Shhhhh, it's alright. You should know by now that I enjoy you going black...even if I do typically feel quite sore afterwards. Besides, I know how much you need this."

Your next words cut me so deep, to my bones...but only because of their piercing truth.

"It can only be assumed that you come to me because you can't have who you really love. I do not blind myself to that fact. I have been aware of it ever since I first welcomed you into my bed."

"Aya...I-"

Your lips hush my words, catching them in your mouth.

"Hatsu, I don't regret anything. If you come again...I'll accept again and again. I know what it is like to love one that is unobtainable. If being with me eases that pain inside you, I will always allow you inside me..."

It was my lips this time that found yours. I could think of no other way to show you my thankfulness. The words wouldn't have been enough, or they wouldn't have come out right. When I pulled away, your eyes let me know that you understood.

I watched you sleep, my fingertips outlining your body, tracing the bruises I left on your flesh. Then I got dressed and left you sleeping alone in your soiled bed.
