You were getting bored.
You, Yuki and Zero were just patrolling around, as usual.
"I. Am. So. God. Blessed. Bored." Yuki said aloud breaking the silence.
" Split up." Zero said as he brushed his white hair out of his handsome face. Without waiting for an answer, he left off into the trees.
" Well I geuss that's fine." You said sarcastically.
"Heh, heh, you and Zero are perfect for eachother:" Yuki giggled.
" What do you mean?!" You said, cheeks getting a bit red.
" He's no fun, you're no fun, you both never smile! He completes you." She said giggling and taking off before you could protest.
" Ugh..." you grumbled and shoved your hands in your pockets. " Why is she such a giddy idiot?" You said as you wandered through the forest. Your h/c hair blew in the wind. But however, due to your constant bickering with yourself, you tripped over a tree root.
You waited for the impact of the ground but it never came.... you slowly opened one of your eyes to see a disapproving Zero.
" Be careful, Idiot." He had his arm around your waist as he pulled you up, you accidentally fell into his chest.
You looked up at his surprised and slightly pink face, and decided to tease him.
" Oh look~" you poked his cheek " The big bad disciplinary comitee guy is blushing." He blushed more as his eyes widened and he let go.
"A- am not!" He sputtered. " I'm going to my room!"
" Whatever big guy." You smirked as he stormed away.
>>> later in front of Zeros door<<<<
" Come on Zero, you're not still mad are ya?" You knocked.
" Yes, I am." He walked out without a shirt on. You blushed a bit as he smirked.
"Ohh looks like I got miss disciplinary committee back for her crime hm?" He pulled on your waist as you slammed into his chest.
"Z- zero what are you doing?" You said startled.
"Ive had a crush on you for a while y/n." He smiled and kissed you passionately.
His tongue bit your lower lip, demanding for entrance. You teased and wouldn't let him, he squeezed your hips and you gasped, he took the opportunity to drive his tongue into your mouth.
Soon, air was a problem.
"I like you to Zero..." you mumbled.
" That's all I needed to hear y/n." He scooped you up bridal style and threw you on his bed, locking the door.
He then jumped on top of you and begun to kiss your neck, biting and sucking on your sweet spot.
You bit your lip trying to hold your moans, becoming slightly wet.
" Don't hold back y/n..." Zero cooed at you. "I want to hear your voice."
" Zero...I- I'm a little scared..." you really were to be honest... you didn't know the first thing about any of this.
" Don't worry sweetheart... I'll treat you like you've never been treated before~" He started to unbutton your shirt as you drug your hands through his hair, after he discarded that: he pinned your arms above your head so you couldn't protest.
"Zero..."
He shushed you and begun to remove your bra with his teeth, a moment later it came off and he dropped it over the side of the small bed. He began to suck on the right and play with the left, causing you to become a moaning mess. He then switched and did the same to the left.
He then spread kisses leading down your stomach to your pants. His hot lips were making you squirm beneath him as he noticed this and begun to unbutton your pants with his teeth.
" Zero please..." you said as you felt your pants slide off and heard them crumple to the floor.
" What?... you don't think its fair that you're the only one almost fully undressed?" He put his legs on your hips, and sat on your legs as he unbuckled his pants and discarded them. His muscular chest was now pressed up against you once more as you felt something hard drag across your bare inner thigh, you yelped and Zero chuckled, amused.
"Y/n... do you want to stop? If I keep going I might not be able to hold back any longer."
" I'm sure Zero... I trust you." You said as he smiled a bit.
" Good answer~" he then proceded to slip your underwear ( because I'm sick of just hearing the words "f/c lace panties") off of you and put his head between your legs...
"Zero!?" You yelped loudly, if it weren't for his elbows holding your legs down they would have moved with your yelp.
" What y/n?" He cooed and slipped his boxers off. He positioned himself at your entrance.
" Don't worry" he whispered in your ear. " I'll be gentle~" he slammed into you without warning as now you didn't care who heard you both.
" ZERO! That's not gentle!" You begun to feel hot tears down your face as Zero kissed you softly and licked the tears off your cheecks, still not slowing down.
"Y/n why are you so tight?.."
He whispered sweet nothing's in your ear and continued for a half hour. He hit your g- spot around that time.
"Zero! There!" Your back arched as he hit exactly there each time."I think I'm g- going to-"
" Me too-" his warm seed filed you and he collapsed next to you on the bed and he pulled you into his warm arms.
"I love you y/n..."
" Fuck you Zero..."
