Okay, I liked this request idea. I'm gonna have fun with this one~

Y/n's P.O.V.

I was repeatedly giggling to myself as I hurried down the hallway. Wait till I tell Laito my next plan. You see, I'm known as the prankster of the house. And Laito was my partner in crime. The two of us came up with all sorts of mischief and pranks for all of the Sakamaki brothers. For the most part, Laito was actually pretty cool to hang out with, except when he decides to be a sadistic pervert. He usual bites me or touches me somewhere to close to my comfort.

But all that aside, all I wanted was to tell Laito my plan. "Laito-kun! Where are you?!" I half whined, swinging my bag around. I yelped as suddenly someone grabbed my wrist and spun me, then dipped me, one hand wrapped around my waist while the other hand kept a hold of my wrist.

"You called, Bitch-chan?" Laito purred. 

"I was looking for you! And I told you to please stop calling me that!" I said. He chuckled and released me. "Not gonna happen, Bitch-chan~" he stated, making me roll my eyes.

"Anyway, I had the best idea for the next prank!" I held out my bag and opened it. He peaked inside, and a wide smirk spread across his face. "Hmm, this should be good~" he murmured. "I'm just not sure who we should prank this time." I said with a small frown. Laito placed a finger on his chin as he looked up, stuck in thought. 

"Hmm. Perhaps Ayato-kun!" he said. "We did him last time though; remember we filled his bath with grape jam. What about Subaru-kun?" I said. 

"Tempting, but we've done him too many times. I feel one more prank and he might snap," Laito said, "We gotta get someone we haven't done yet. Someone who's dangerous~ Someone who would never see it coming." Laito stated. I tilted my head.

"But we've gotten everyone, even the Mukami brothers. The only one we haven't gotten was...." Laito and I both perked up and shared a smirk.

"Reiji-kun!"

Small time skip

I was giggling like mad, watching Reiji from around the corner of the room he was in. He was currently reading a book beside the fire, seeming focused. I was shaking so violently from eagerness that I struggled to hold the cup of tea I had. Laito chuckled and gave my back a firm pat.

"This won't work unless you keep your cool, Bitch-chan." I took a deep breath and nodded, and put on my serious face. We both agreed that I would be the one to deliver the tea since Laito, already having a mischievous reputation that was deeper than my own, would be too suspicious. I put on a smile and entered the room, approaching Reiji. He raised a brow as I came towards him.

"Y/n, what are you doing here?" he asked. 

"Gomen, I didn't mean to disturb you. I just wanted to give you this cup of tea I made." I replied, handing it over to him. He looked to me, then the cup, then back to me.

"You made me tea for no occasion?" he said. "Oh? Do you not want it? Well, if that is the case, I guess I could give it to Kanato-" he narrowed his eyes and immediately took the cup from my hands, careful not to spill it.

"I didn't say I wouldn't take it." he stated. I had to swallow my laughter as I saw him raise the cup to his lips and take a sip. He pulled the cup away, licked his lips for a moment.....then his eyes widened. He gave a small cough as sweat already formed on his forehead. 

"W-What did you put in this tea?" he asked.

"Nothing abnormal...." I murmured. Just some hot sauce. His coughing only continued, and he eventually stood up as his face took the shade of a light pink. "You don't look good. Maybe you should go get something to drink from the kitchen." I said. Reiji didn't respond, but rather speed walked to the door and exited the room. When I could no longer here his footsteps I finally roared in laughter. 

He obviously tasted the hot sauce. He did everything he could to keep his composure while not trying to scream in pain. Oh man I can't wait to see what he'll feel when he goes through the next phase of our plan.

Laito's P.O.V.

I gave a small yawn, adjusting my coat.

"Three, two, one...." in a matter of seconds Reiji burst into the kitchen, his face a shade of pink. I smirked as I approached him.

"Oh, Reiji-kun. You don't look good. Do you need a beverage perhaps?" I asked. He only answered with a wordless heave and nodded. I went to the bottle I had prepared on the counter and handed it over to him. I was about to open my mouth to tell him there was water inside, but he already took the bottle and gulped what was down. I placed a hand over my mouth to stifle a chuckle. Oh man he's gonna get it now.

Reiji's eyes snapped open and he tossed the bottle aside, spitting out the red liquid that was inside. Did I mention I actually put in some spicy onion/tomato sauce in there that was sprinkled with bits of chili pepper savings. He heaved out, placing a hand on his throat and coughing.

"What the hell was that concoction?!" he shouted. I put on an innocent expression. "I was about to tell you, Reiji-kun, but you drank it right away without waiting for me." I replied. He growled at me as his eyes began to water, fogging his glasses.

"However, perhaps that cake over there will help cool whatever burns your mouth." I said, gesturing to the cake that sat on the table nearby. He snapped his head towards it and dove for it, grabbing the fork I had provided digging right in. By this time Y/n had finally came in.

"How are thing's go- oh my." she giggled as she watched Reiji scarf down the cake. She had to look away to cover her mouth.

"Oh god...."

"What's in that cake, Bitch-chan?" I asked. She was the one that made it, so I was unaware of the ingredients inside it. "....ghost peppers." the moment she said that, Reiji spat out the cake and screamed in pain. And don't go saying he could die, because we vampires are much tougher than you might think. 

"Reiji-kun, just calm down. If you lift your head up and open your mouth, we can make the burning go away." Y/n explained as I went to the rope, ready to release it. Reiji, too dazed in pain to think of his dignity, did as told and tilted his head up with an open mouth. I released the rope....and a bucket of milk spilled onto him, most of his going inside his mouth. I could almost see steam emit from his mouth as the milk made contact with his tongue. By this point, Y/n and I were laughing nonstop, almost falling onto our legs.

Reiji swallowed whatever milk was in his mouth and sighed in relief. Y/n looked up at the second oldest, finally calming down from her laughter.

"Looks like we got you good, huh Reiji-kun?" she said. There was a long pause of silence. The atmosphere suddenly felt tense, making me frown. Y/n could feel it too for she suddenly looked at Reiji nervously. 

"Uh, Reiji-kun...." I could practically see the dark aura around Reiji. He straightened his posture and adjusted his glasses. 

"You two.....are so very dead." Y/n yelped as he suddenly lunged forward, making my eyes widen. 

"Time to go!" I grabbed onto Y/n and we teleported out of there. 

Y/n's P.O.V.

I yelped as Laito suddenly teleported us out of the kitchen. The next I was met with a cool breeze and the night sky. I looked down, seeing the garden from high up. Oh, we're on the roof aren't we? I looked to Laito, and he looked to me. 

Then we both burst into laughter.

"Hahahaha! Did you see the look on his face?!" I laughed plopping down on the edge of the roof. Laito nodded, sitting beside me. "That was great! I never thought in a million years I'd see him in such a state! He always makes sure to look the most professional, and then he looks like that....ha!" Laito stated. I sighed happily.

I really like this. Playing games with Laito like this. Getting to hear his laugh. Getting to see those beautiful, emerald eyes he has. They were so deep and mystical, they could look into your very soul. I turned to Laito so I could see those eyes again, but blushed when I saw him staring back at me, a smile on his lips.

"N-Nani?"

"You're very pretty." he said. I blushed brighter as he scooted closer to me, reaching a hand out to brush my hair away from my shoulder. He sniffed the air before sighing.

"Ne, Bitch-chan. Gomenasai, demo it would seem I need to bother you for something to drink. All this excitement has made me rather parched." he said. I frowned, knowing exactly what he meant. I sighed, looking away and moving my hair away, showing off more of my shoulder.

"Go ahead then." I muttered. He gave a long lick across my skin before sinking his fangs into my shoulder. I winced, feeling the pain pierce into me. I hated it when he did this, but it wasn't like I could resist. You try saying no to any of the Sakamaki brothers when they are thirsty for blood. Besides, this was something I had grown use to. It was the only reason he hung out with me anyway....

Laito pulled away, licking his lips in satisfaction, then looked to me with a smile. However he frowned when he saw my sad expression.

"Doshtano, Bitch-chan? Why the sad face?" he asked. I didn't look back at him, pulling my legs to my chest and hugging my knees. 

"Laito-kun....you only like me for my blood, right?" Laito blinked, seemingly taken aback by my question. "What do you mean?" he asked. 

"You know what I mean. You only hang out with me because you want my blood close to you at all times. I mean, do you really mean it when you say I'm pretty or funny? I bet you've said that to thousands of other girls." I stated. 

Laito's P.O.V.

I looked at Y/n shocked. Did she really think I felt that way? Well, I mean I have felt that way.....right? But she is actually fun to play with, and she is very beautiful compared to the other girls I met. She is a nice girl all around. But....does that mean I love her? I looked back at the girl, seeing she still had that depressed expression on her face. I don't like seeing her sad, it makes my heart swell. I'd rather see her happy.

"Ne, Y/n-san. Don't look so mopey. You look a lot better with a smile on your face." I said, nudging her shoulder. However her expression didn't change. I frowned. What can I do to cheer her up? I placed a finger on my chin, thinking over what to do....maybe a joke will cheer her up.

"Ne, Y/n-san, wanna hear a joke?" That made her perk up a bit.

"A man is drowning out in sea. Suddenly a boat drives up to him saying 'Want some help there?' and the man says 'No thanks, God will save me'. The boat left afterwards. A bit later, another boat shows up saying 'Hey, want some help?' and again the man refuses, saying that God will rescue him. So the boat drives away. The man drowns and is sent up to Heaven. When he arrives he asks God, 'Why didn't you save me?' and God replies 'I sent you two boats, you dummy." I explained. 

That made Y/n laugh hard, holding her waist. I chuckled with her, and soon our combined laughter howled in the night. When we had calmed down, I wrapped an arm around her waist and pulled her close, making her blush.

"Laito-" I kissed her forehead.

"Now, if I just wanted you for blood, would I really try to cheer you up just now?" I asked. Y/n looked at me in shock, then she smiled. I held her closer and we cuddled close. 

"Arigato, Laito-kun." she said. I nodded as she scooted back. "It's no problem, Y/n-san. I hope you know, I love being beside you and playing pranks on others. Especially what we did to Reji back there. Hahahaha! We should do him again real soon...." however I trailed off as I saw Y/n was staring past me, a nervous expression on her face.

"Y/n-san?" I suddenly felt a hand on my shoulder.

"Laito-kun," I yelped at the sound of Reiji's voice, "I think the three of us need to have a chat." Reiji stated, his voice laced with anger.

"Oh shit...."
