(Mukuro's POV)

My job here is finally done…it took 7 long years, but I can finally return. I wonder how that boy is doing. Did he move on to someone else? Did he forget about me…should I even return to him?

"Mukuro-sama. Are you going to attend the Vongola Family's Holiday Party tomorrow?" Chrome ask as she approach my desk.

"I think I will pass on that this year," I quickly stood up and gather my belongings and coat. "I will be gone for the time being. Do not expect me back any time soon."

"Yes, Mukuro-sama."

... ...

(Allen's POV)

"Welcome back, Allen!" Lenalee cheers as I and Kanda walk through the door from our mission. "Merry Christmas Eve and happy early birthday!"

I slightly blush from her excitement, "Thank you, Lenalee! You remembered!"

"Of course, I remembered! How long have we been friends!" She lightly pats my head as I giggle to myself.

"Maybe you'll grow taller, Moyashi," Kanda huffs.

"Hey! I hit my growth spurt! I am just two inches away from your height!" I shouted.

"Three inches, baka."

"Two!"

"Okay okay! No fighting! Did you want to stay up and countdown to your birthday?" Lenalee offers.

I thought about it more and sigh, "Actually…I am pretty tired from the mission. I'm sorry guys, I am going to sit out of this year's countdown."

"Aww! Well, we will be in the lobby if you want to join us anytime! Also, your presents are in your room, near your closet!" Lenalee smiles.

"Thank you," I grin as I wave good-bye to both of them and head back to our room and yes, I am still staying in the room that I have shared with Mukuro. I just sleep in Mukuro's bed…silently hoping that he will come back one day. The cold winter air whistles through the hallway as I was deep in thought thinking about Mukuro. Wow…it has been 7 years now. I realize that I have not celebrated my birthday with him at all…that thought made me very sad. DAMN IT, MUKURO! Where are you? I desperately miss you…I miss your sly attitude and gentle touches…

Even though I have only known him for a couple of days, why am I so obsessed with waiting for him to return to me…

It could have been just an empty promise and I am waiting for nothing. I might give up this year…but I also feel like I have already gone this far...what else do I have to lose? I do not know what to do…I should try to get some rest tonight.

After slowly opening the door and flipping on the lights, I suddenly saw a large lump under the sheets of MY bed. I do not want to get my hopes up…it can't be Mukuro…can it? I slowly walk closer to the bed and while walking closer, I accidentally stepped on a loose floor board and produced a loud creak sound…the figure slowly turns over to his side and I was able to see the face of my intruder…MUKURO!

I immediately leaped onto Mukuro's body, knocking the wind out of him and waking him up successfully.

"ACK! Oof! Ah…that really hurt…A-Allen?" Mukuro mumbles as he rubs his eyes open.

"YES IT IS, JERKFACE! WHAT TOOK YOU SO LONG!" I yell while tears of relief and joy stream down my cheeks.

"I deeply apologize, Allen. My subordinates and boss were highly demanding and persistent. I spied on you while I slept for the first year we were separated, but then things hit the fan between the mafia families and I was not able to spy on you anymore due to the fear of being caught and putting you in danger. I have missed you...My…how you have grown…you are absolutely beautiful…" Mukuro sighs as he gently strokes my now long white hair. He brought some strands of my hair in his gloved hand close to his lips as he kisses it while looking up at me. I got lost in those ruby and sapphire eyes that I unconsciously adjusted myself so that I am straddling his waist, feeling his firm abs under me.

"Speak for yourself…I didn't think you could get anymore handsome."

"Oh really?" Mukuro purrs against my ears, "I don't think I have changed at all...but it depends on where you are looking..."

I moan from the sound of his voice and I sit back to admire him more, "So…how's everything? D-Did you ever forget about me?"

"Never, not even in my sleep," Mukuro whispers as he leans in and grazes his lips against my cheek and neck. "I missed you very much…"

"I missed you too, Mukuro," I lean in and kisses his lips. I could feel his arms wrapping around my waist and hip as I caress his cheek with the back of my hand. I touch my tongue against his smooth lips, asking for entrance and I could feel his lips part. I eagerly explored his mouth as he ran his hands down my back and grab my butt, giving it a tight squeeze. I gasp lightly and pull back a bit to look in his eyes. "T-This is really you, right? Not an illusion?"

"I am here…flesh and blood…I love you."

"I love you as well…please do not leave me again."

"I am not going to let that happen…however, I hate to be a damper on the mood, but I am curious…how old are you now?"

"Huh? You don't remember my age?"

"Nope! I only remembered that you were not of legal for me to ravish 7 years ago."

I could feel my face turn pink, "S-Seriously?!"

"Yes, my dear. Why did you think I held myself back?"

"Mukuro!" I pout.

"I apologize, Allen. I only just recently found out that your birthday is tomorrow…I am a very bad lover…" Mukuro replies with slight hurt in his eyes.

"Ah! It is not your fault! I will forgive you if you agree to my birthday wish…"

"All right then, what's your wish?"

I can feel my face getting redder as I quickly lose my confidence, "I-I…want you. All of you. Y-You do not need to worry about age this time…I'm 22."

"Kufufu, I am honored to make love to you…also out of curiosity again…will this be your first time?"

"Y-Y-You are not allowed to ask that!" I cover my face with my hands.

"May I assume that no one else have touched you the way I do?"

I sat in silence for a moment, just basking in the embarrassment, "Baka…of course this is my f-first time…I waited for you, right?"

"Kufufu," Mukuro chuckles as he reaches towards me and starts unbuttoning my shirt. He then leans in and begins sucking on my neck and collarbone leaving small kiss marks. I moan softly as I tug on his shirt to pull it over his head. Mukuro discards my shirt as I discards his as well and I sat there staring at his tone, firm body… I unconscious blush while Mukuro catches me staring at his body. "Do you see something you like, boy?"

"Oh yes…very much," I reply as I undo and pull at his belt. Mukuro leans in closer and starts sucking and licking at my chest. "A-Ah…" I gasp and give a final tug to remove his belt. "More—I want more…" I moan and unbuckle his pants and zip it down. I slowly slid my hand against his clothed member, already feeling the heat from it.

"Eager, aren't we?" Mukuro whispers hotly against my ear.

"Yes…I want you now."

"Don't worry, your wish will be granted. I just need to prepare you," Mukuro smirks as he lays me down on my back and pulls my pants down roughly. He tosses my pants and underwear onto the floor with the rest of our clothing. I could feel his stare all over my body as I lie bare naked for him to see everything.

"Um…ah…" I cover my face with my hands to hide my embarrassment.

"You are absolutely beautiful," Mukuro leans down and starts caressing my member.

"A-Ah! M-Mukuro!" I hear myself moan louder and louder.

Mukuro turns my body over so that my back is facing him, "We do not have lube, so I might have to use my own saliva."

"W-Wha?" I did not comprehend his words, but I felt my mind going blank after he inserted his tongue into me. "A-Aah! Y-You! Ah!"

Mukuro retreated his tongue and starts prodding his fingers into me. I could feel his slender fingers going in and out of me and how it is making a lot of wet noises. Mukuro starts to scissor his fingers and add a third one into me. I moan out and gasps from the friction. "I am going to add another finger, okay? I want to make sure you are stretched out and ready for me," Mukuro pants.

I gave a small nod, preparing myself for the worst. I could feel my body aching slightly from the different sensation. Mukuro adds the last finger and starts thrusting his hand gently against my body. "Ah-Ah…Aaaah!" Before I knew it, I came onto the bed sheets. "Ah…I-I so sorry…"

"It is quite all right, Allen," Mukuro smirks. "You did just fine. Are you feeling okay?"

"Y-Yes…please, I want you to feel good too!"

"Kufufu, do not worry about me Allen."

"N-No!" I turn myself around and climb on top of Mukuro. I pull down his underwear to reveal a very large member. "Gulp. You are so hard and big…"

"Yes, I am…and I have been doing my best to hold back so I won't hurt you."

"I do not want you to hold back," I said as I position myself on top of his member and gently try to ease it into my body. I moan loudly as I fit half of him inside me. "Ah, ah…Ah!" I pushed myself down onto him and pleasure and pain shook my body.

"A-Allen, are you okay?" Mukuro flinches at the pressure, "You are so tight…please take a deep breath."

I took a couple of shaky breaths and I held onto Mukuro's shoulders to stabilize myself. "Ha…aah…I want you…now," I wheeze.

Mukuro slowly thrust into me and I thrust against him. I want to rile him up and make him feel good. Mukuro eventually thrusts faster and faster until my mind turns blank and both of us moaning and grunting until night is over.

(Mukuro's POV)

I woke up to Allen's soft whimpering. Why is he crying? I gently shake his shoulders, but he is still asleep. "Hey…Allen. Allen. Shhh, everything is okay," I cradle him into my arms.

"M-Mukuro…" Allen whispers.

"Hm?" I caress his deformed hand and held it in mine.

"Promise to always stay with me?"

I kiss the top of his head and rest my cheek against his soft hair, "I will never leave you...promise."

The End
