****** Swear Not by the Moon ******
by RosieRaven
Summary
     I would never understand Oikawa; how his emotions could turn on a
     dime from cynical, to happy, to angry- it never made sense to me. He
     never made sense to me.
Notes
     The title come from one of my favorite bits of Shakespeare-
     O, swear not by the moon, the inconstant moon,
     That monthly changes in her circled orb,
     Lest that thy love prove likewise variable.
     It seemed fitting with these two and their weird mix of admiration
     and abject hatred.

Oikawa’s text came out of nowhere. Well almost nowhere. I'd half expected this
ever since I heard Shiratorizawa Academy had won the finals. 
 Meet me in the park 
The lack of a question mark irritated me, like it didn't even cross his mind
that I might not want to go. The fact that I was going was irrelevant. It was
still presumptuous given what the past forty-eight hours had been like. 
It was late, but my parents slept like the dead, and the park was only a short
walk from my house. It was a warm night; streetlights threw long shadows over
the grass and the moon hung full in the sky. The park, noisy and filled with
people during the day, was completely deserted.
Oikawa sat under a tree, leaning back on his hands with his legs splayed open
in front of him. Though my shoes rustled the grass, he didn't turn to
acknowledge me. I sat down as well, content to say nothing. We waited silently
in the semi darkness until he finally spoke.
“We lost today.”
My jaw tightened and I didn't bother to hide the bitterness in my voice, “You
certainly wouldn't be here if you’d won.”
He finally turned to look at me with a wry smile, “And miss the chance to rub
my victory in your face?”
My teeth ground together and I tore up a handful of grass with my fingers, “But
you didn't win, you lost. You took our chance away and then you lost anyway.”
Oikawa's good humor was gone in an instant, “You thinkyou could have done
better?” His tone was scathing, and I was thrown by the abruptness. I would
never understand that about him; how his emotions could turn on a dime from
cynical, to nonchalant, to angry- it never made sense to me. He never made
sense to me.
He reached out and grabbed my chin, fingers tight. “You think you could have
done better than me little king?” His eyes kept boring into me, anger and heat
boiling under the surface. I squeezed my eyes shut against him as his thumb
brushed firmly across my lower lip and he exhaled deeply through his nose. I
could feel his breath against my face and, fool that I am, I tilted my head to
meet his lips.
The kiss was harsher than I was used to. Usually Oikawa was playful, teasing to
the point where I wanted to throw up my hands and leave, but there was no
playfulness now. He cupped my jaw firmly  and my lips were crushed between our
teeth. I pushed against his shoulder and wrenched my head back, breathing
harshly. Though the kiss had been short, our limbs were already tangled
together and I was halfway in his lap. A sliver of light illuminated Oikawa’s
face. His eyes were wild, like he couldn't decide whether kiss me again or hit
me.
I shook my head, arms still tangled around him, "What do you want from me?”
Oikawa's voice was low, his hands smoothed down my back as he spoke, "I had a
bad day Tobio. Making you squirm always makes me feel better."
"What, You don't have anyone else you can torment?" I snapped.
“It’s more fun to take it out on you," he said.
My hand, tangled in his hair, tightened into a fist. He let out a little gasp
of what might have been pain, but it was accompanied by a smirk. "Don’t pretend
you don’t feel the same way. You've been hoping for this all day." His hand
dipped down, pressed firmly against the front of my shorts, and I couldn't stop
the ragged moan that came out of my mouth. “What? You want to stop?” he
taunted.
I pulled him down to me and kissed him hard, the same way he’d kissed me only
moments ago, my teeth digging into his lower lip. I wanted  him to suffer, I
wanted him to hurt. Who had I been trying to fool? I'd known from the moment
Oikawa texted me that this was where I’d up tonight, with his tongue in my
mouth and his hands on my body. He pressed forward and with a sudden thump I
was on my back. When he pulled away, his bottom lip was red and swollen. He
slowly licked his palm and shoved it unceremoniously down the waistband of my
shorts. My hips jumped up at the unexpected contact, a jolt of electricity
running up my spine as his fingers wrapped around me. I pressed my lips
together, but even that couldn't suppress the desperate noise that welled up in
my throat. 
Hungry to touch him in return, I tugged his shirt up, needing to feel him skin
to skin. He shoved his own shorts down, but when I reached out to touch he
grabbed my wrists pushing me down again. He tugged a bottle out of the pocket
of his discarded shorts and squeezed a large dollop of liquid. He rubbed his
hands together, then wrapped his slick fingers around both of us. My back
arched up off the ground and my fingers dug into the turf above my head. He
moved his hand slowly, It was a struggle not to wriggle my hips and beg him to
hurry.
 Oikawa removed his hand and my face screwed up, "Oh come on!"
"Don't be impatient," he hummed. Oikawa aligned out bodies and pressed down,
trapping our erections between our bellies.  His arms wrapped around me,
crushingly tight and his his breath was hot against my ear. He slid himself
against me and we both groaned. My knees felt weak as our legs twisted
together, keeping us close as he began to thrust his hips back and forth. I
threw an arm around his waist, desperate to keep the friction and the pressure
going. Oikawa's movements became harder and faster. Everything else started to
sink away, and all my attention became focused on the ache building in my dick.
I hadn't realized how much I needed a distraction. Something, anything else to
think about after the tournament and my failure.
Oikawa finished first, he always finished first. He'd never been one to put off
his own pleasure. His pace became more erratic and he turned his head into my
neck, breath coming out in a sob. I felt him spill his come onto my belly and
his body went limp on top of me. I rubbed a hand over my face, resisting the
urge to scream in frustration.
But it wasn't over yet. Oikawa's own orgasm wasn't enough for him. His hand
snaked down between us and he gripped my cock hard and started to pump me
ruthlessly. I cursed him loudly my body twisting under him as he squeezed. I'd
never liked the way another person could make me come, make me lose control. Of
course Oikawa knew I didn't like it, which was probably the reason he always
made sure I finished. The bastard.
His mouth sucked at the spot where my neck and shoulder met, making me squirm.
He kept one arm wrapped tightly around me, as he worked me over with
unforgiving tenacity. The sensation was too much, the pressure too great. I
couldn't help myself. My body arched up into his hand, my nails dug into his
skin, and I bit my lower lip between my teeth trying to hold back a pleading
keen.
“Come for me,” he cooed, his voice oddly tender, “Come for me Tobio-chan.”
A strangled cry wrenched itself from my lips as his touch and his voice pushed
me over the edge.  My body went pleasantly limp, and for a few brief minutes I
lost the power to think, which was rare for me. The whole world melted away and
the only thing that mattered was the other body tangled up with mine on the
cool grass.
Oikawa didn't move from where he lay, half on top of me. His nose pressed into
the crook of my neck and I couldn't see his face. His arms still pulled tight
around me and his breath was still ragged. The brief sense of peace I'd felt
all evaporated as I felt hot tears against my neck. My throat constricted,
fingers tightening on his shoulders.
I couldn't deal with this, I didn't know how to deal with this. I could take
anything else from him, his mocking, his frustration, his anger, but I couldn't
comfort him. I couldn't pity him. He had to know I couldn't pity him, not
 after everything that had happened. His shoulders shook and I felt my own
composure start to break. All of my own disappointment came back full force and
I was too tired to resist it. I buried my face in his hair, consumed with the
same selfish sadness at my own failure. I’m not sure how long we stayed that
way; his head tucked under my chin, my fingers combing through his hair. Both
of us indulging in misery.
My phone chimed in the nearby grass, breaking the spell. I pawed it closer,
trying to move as little as possible. The brightness of the screen made me
flinch. It was later than I’d thought, and my battery was dying. If my parents
woke up and couldn't find me this time of night, there would be trouble.
“Shit," my voice was ragged, "I have to go home.
Oikawa sat up, saving me from trying to figure out how I was supposed to get
out from under him. He ran his fingers ineffectually through his hair, trying
to tame it.  “I suppose it is late for you to be out, eh Tobio-chan.” The
brightness of his voice as he  fixed his clothes was jarring. It seemed Oikawa
was himself again, only a slight redness in his eyes and roughness to his voice
betrayed the fact that he’d ever come undone in the first place.
 I frowned down at myself, disgusted at the mess. Thankfully there was a
drinking fountain nearby,  I wet a corner of my shirt and tried to get rid of
the worst of it. We didn't talk as we cleaned up, the only sound was the soft
splashing of the water and the rustle of clothes. Oikawa started to hum. I
shook my head and scrunched up my nose. 
"I should delete you from my phone."
He shrugged and splashed some water on his face, "Do what you like."
I pinched the bridge of my nose, already able to feel the headache coming. My
mood was even worse now than it had been before, and meanwhile Oikawa was back
to his flippant self like nothing had happened. I tugged my shirt back on, "I
should never have come here." 
He brushed his hand against my cheek, “Don’t be sad Tobio-chan,” he said. His
voice was mocking but his eyes were hard, “After all, you can try again next
year.”
"Shut up."  I knocked his hand away from me, harder than I had meant to, but
Oikawa just laughed. Before I could stop him, he leaned in and licked my lips. 
Wiping my mouth, I jammed my phone in my pocket and turned away, "Ugh, Okay I'm
leaving now."
"Sweet dreams Tobio-chan!" 
I crossed my arms and walked faster, "Go home Idiot."
