****** I Want You To Sleep With Me ******
by LucasPSI
Summary
     It quickly becomes apparent to Hackmon that lately, Rei has been so
     busy with his work that he hasn't been taking care of himself
     properly. Even to the extent that his partner now sleeps on the couch
     just because it's more convenient than his own bed. Needless to say,
     Hackmon can't help but worry over this.
"Rei... Rei... Rei..."
"What?" The young boy with faded green hair asked, still typing away at his
computer and not bothering to look for where the source of the sound. The
source being his partner appmon, Hackmon. It was obvious that with the response
he got from his buddy, there was no point in Hackmon continuing the
conversation. He was clearly too preoccupied with something else to listen. But
alas, the appmon continued on with already arranged list of questions.
"When was the last time you ate?"
No response. His partner just continued typing away at his computer like he
always does. Sadly, this was the norm between these two. Whenever Rei was
cought up in something he very rarely paid any attention to the outside world.
This included even his own partner. Hackmon could wander off on his own and it
would be days before Rei would realize he was gone.
"Rei... Rei... Rei..."
"What is it?" Rei asked once again. This time he turned his head ever so
slightly to give the impression that he really was listening. From the looks of
it, Hackmon must have caught him while he was in the middle of loading
something. Now Rei had to listen whether he wanted to or not.
"When was the last time you ate?"
"I ate last night."
"What?"
"I had some energy gel"
"That's not food..." Hackmon's ears drooped slightly. While he rarely ever
shows his concern openly, the idea of his partner not having a somewhat
balanced diet bothers him greatly. Especially since as far as he knows, a well-
balanced diet is required for humans. He learned that energy packets are fine
once in a while and that most who are busy use them regularly, but they
shouldn't be the only thing humans consume for days on end.
After a few seconds of staying silent it's clear Rei wasn't going to comment on
this subject again, so Hackmon turned to something else that's been on his mind
all morning.
"I noticed the blanket lying next to your computer desk. Did you sleep on the
couch last night?
"I did." Again with the straightforward remarks...
"That's not good for your back. You have a bed for a reason. You should be
using it."
"You were using it."
"I don't take up very much space. We could have easily slept together."
If Hackmon had any sense of humor he would have laughed. Dealing with Rei was
almost like dealing with a child. Not to say Rei wasn't a child. In his time in
the human world, Hackmon learned that those his age do tend to have a
rebellious phase. Most grow out of it, some don't. Hackmon has a feeling that
Rei definitelly won't be growing out of his anytime soon on account of the
things he has gone through. What Rei's gone through in the past few years is
something most wouldn't even be able to believe.
It doesn't help that because of his past, Rei is so socially awkward that he
hasn't made the effort to really get to know anyone since he had met him. It's
a shame because Hackmon, while he is a huge loner himself, feels that he and
Rei could form a stronger bond if Rei would just open up a bit and realize that
Hackmon only wants to help him and support him.
"Rei..."
"Rei... Rei... Rei..."
"What?" The boy responded, this time with a bit of annoyance in his voice.
"I want you to sleep with me tonight." The tiny appmon said sternly and firmly.
Rei was caught off guard by this sudden line of dialogue and immediately
stopped typing. He slowly turned his chair to where he was he was looking
Hackmon in the eyes. "What?"
"Rei, I want you to sleep with me tonight."
The two just sat there staring at each other as if waiting for the other to
break the silence.
"I want you to-"
"I heard you the first time." Rei said cutting him off.
"You hardly ever get a good nights rest. It's plain as day from the bags under
your eyes and your constant yawning. And you may not realize it, but you've
been rubbing the back of your neck a lot since this morning. You can't keep
sleeping on the couch like you've been doing. Eventually, it'll kill you... All
the work you put into finding Leviathan will be meaningless when you're dead."
"...Fine." Rei said suspiciously nonchalantly as he turned to continue his
world. "But I don't need you there. It's not like I'm afraid of the dark." Rei
comically pointed up at a broken ceiling lamp. Neither of them could remember
the last time they changed a bulb in their apartment. They've practically been
living in the darkness for months.
"I need to. I need to be there to confirm that you're actually sleeping. I
don't want you to just get up in the middle of the night and head back to your
computer. If me being there bothers you that much I'll sleep on the floor. But
I really do feel like I should be in the same room, at least."
"Hah, my own buddy doesn't trust me." Rei said looking away. But despite facing
away from his partner, Hackmon could still imagine the smirk on his face.
"10:00.... 11:00... 11:30..."
Hackmon sat patiently on his companions bed waiting for him to be finished with
his work. It sure was getting late. For a second, Hackmon had a feeling Rei
forgot about their little agreement, but his desire was finally realized when
he heard the bedroom door creak open. In walked his partner dressed in his
sleeping attire. His sleeping attire being his usual grey long-sleeved v-neck
shirt and his usual pair of pants. Basically all he did was take off that black
hoodie that he always wears.
"You're late. It's almost midnight." Hackmon said as Rei pulled back the
covers. Though, to be fair, Hackmon was surprised to see him before midnight at
all. He was already prepared for the possibility of having to go into the
living to drag his buddy out.
"I was busy." Rei began climbing into bed. Hackmon was just about ready to jump
off to make room when he heard Rei's voice.
"You don't have to get off. You were already here before me anyway." Rei said.
Hackmon did just that and stayed where he was at the foot of the bed. He
stretched himself slightly and gave out a quiet yawn, not too different from
how a dog would before lying down.
"Did you brush your teeth?" Hackmon said before shutting his eyes and drifting
off to dream world.
"What?"
"Did you brush? You're suppose to do that before bed, you know." Hackmon stood
himself up on all fours and turned his head in Rei's direction.
"Of course I know that." Rei said with slight aggravation in his voice.
Not being fully convinced, because knowing his partner, why would he, the tiny
appmon inched closer to Rei.
"What are you doing?" Rei asked.
"Sniff check." Hackmon said.
"You're kidding, right? Are you my mom now?"
"It's the easiest way for confirmation."
"Actually, the easiest way for confirmation is by taking my word for it." Rei
said, gently putting his head on Hackmon's head to try and prevent him from
coming any further. Hackmon just kept pushing so Rei let him have his way to
get things over with.
Rei sat up slightly and leaned against the wall at the head of his bed.
Standing on his hind legs and placing his two front paws on Rei's chest,
Hackmon leaned in closer and closer until he was just a few inches away from
his face. "Oh, you did. Very good."
"Of course I did." Rei winced a bit as he could faintly feel Hackmon's claws
poking him through his shirt.
"This is the fist time I've ever seen you this close. Sometimes I forget you're
a tiny dragon under those dirty robes of yours." Rei lifted his arm and began
to rub Hackmon from his back all the way down to his tail. "Now go to bed."
"My robes aren't dirty."
Hackmon's body shuddered from Rei's soft but also firm touch. He turned his
gaze ever so slightly away. Petting was one of his weaknesses. Especially when
it was his tail that was being pet.
"Rei..." Hackmon said quietly as his mind was almost lost in bliss just from
being pet like a dog. He didn't want to move.
Rei reached up and caressed hackmon's cheek before leaning a bit forward
himself and giving Hackmon a tiny kiss on the nose. For a split second Hackmon
was taken aback.
"Sorry, Hackmon. I know I can be stubborn sometimes. I know you're just want to
look out for me as my partner." Rei said quietly, almost as if to make sure
nobody else could hear. Not that anyone else was even around to hear him. Rei
continued to silently pet Hackmon.
Hackmon wasn't sure what to say. Was this really Rei? This certainly didn't
feel like him. Or rather, this is the real Rei. The one he's not use to. The
Rei who's a loving older brother. The Rei from before the whole Leviathan
incident. He's sweet. Much different from how his usual rude straightforward
self is.
Rei held Hackmon close as Hackmon leaned againt Rei's chest. Ever since he lost
Hajime, Rei probably longed for any kind of affection, whether even he knew it
or not.
And now, Hackmon was ready to give Rei any kind of affection he desired.
As Rei pulled away slightly, Hackmon leaned forward as if to pull him back. He
gently licked his human partners lips unsure about what his partner would
think. He could tell by Rei's expression that he was taken aback much like how
he was a second earlier. Rei's sudden change of expression didn't last long
however as he quickly reciprocated with a gentle kiss.
Hackmon's mouth tasted far different from a humans. At least, as far as Rei
knew. This was the first kiss he's ever shared with anybody. He could only
assume it was the same for Hackmon.
It didn't take long for their tongues to meet. Unsurprisingly, Hackmon's tongue
was larger in comparison and in no time at all it practically forced its way
into Rei's mouth. As their tongues battled for dominance, Hackmon could feel
his mind going blank. He dug his claws deeper into Rei's chest, but even still,
Rei held him close. Neither of them wanted it to end.
Eventually the two had to separate but only to catch their breath. It was
difficult for Hackmon to look his buddy in the eyes so he just kept his head
tilted down.
Hackmon slowly backed away from Rei's chest and positioned himself to where he
was now sitting in the humans lap. Just beneath him was a very prominent bulge
that wasn't there before. Hackmon placed one paw against it and gently rubbed
it. Even with the material it was being contained by, it was obvious what it
was that he was touching.
"I thought this whole thing started because you wanted me to get some sleep."
Rei said in an almost cheeky tone.
"I'm sorry for my selfishness." Hackmon slowly pulled back Rei's pants and
underwear to reveal his throbbing half erect member.
Hackmon's paws were shaking. He's seen his fair share of naked humans with all
his spying and hacking through the net. Male and female. Neither was much of a
turn on for him, anatomy-wise. Probably because of the fact that humans are
another species altogether, or probably because being an appmon, those types of
urges weren't built it. As far as he knew, appmon didn't even have the right,
"equipment" for fulfill those urges. But even still, it'd be wrong to say he
didn't have such urges right now. Seeing his partner like this, especially this
close, is almost too much to bear.
"You're not being selfish." Rei responded. He placed a hand on Hackmon's head.
Hackmon placed his paws on Rei's legs to keep them spread as he leaned his head
down. In an effort to get positioned correctly, he felt his face bump up
against Rei lightly. The scent of it filled his nose immediately. The smell was
hard to describe, but not bad. Gently, he licked the head of Rei's cock. He
could practically feel the vibrations running through Rei's body as the boy
jolted from the soft touch of the warm, wet tongue.
He licked it again and again and again. It felt as though it was getting harder
with every touch. It wasn't long before he could taste a salty yet sweet
substance coming from the tip. Rei never said a word so Hackmon assumed what he
was doing was right.
He continued to lick elsewhere. He rested his tongue down at the base of Rei's
cock and licked upwards coating the underside in saliva. Again, again, and
again, he repeated this method. He licked all over making sure to get a taste
of every inch. In the background he could faintly hear Rei's breathing getting
louder. It was bliss.
Hackmon opened his mouth wide and positioned his head directly above the fully
erect member before dropping down and taking the tip of it into his mouth. He
had to be extra careful with how sharp his teeth were. They were far sharper
than a humans. He slowly moved his head down taking in more of the boys length
until he could feel it in the back of his throat. The same salty yet sweet
substance was gone and replaced with an almost sour taste. Though, it wasn't
unpleasant.
He pulled back for much-needed breath before immediately going back down for
more as soon as he could. Eventually, he got to the point to where he was
comfortable enough to start bobbing his head up and down in a rhythmic motion.
As the appmon continued, Rei moved his hand down to trace one of Hackmon's
ears, not so much as to guide him, but to caress him lovingly and let him know
he was doing good. Hackmon couldn't contain his own pleasure by this point as
his as his tail wagged with glee.
"Perfect, just like... that." Rei spoke in a soft tone as he rubbed Hackmon's
back.
Suddenly, Hackmon could feel Rei's grip on him tighten. He didn't need to be
told to know that his partner was nearing his climax. In the back of his mind
he figured it would probably be best to pull away, but the rest of his mind was
so hazy with pleasure that his body wouldn't listen to him if he tried. He felt
a slight tug on his hood as Rei apparently tried pulling him away, but Hackmon
wouldn't move.
Hackmon could feel thick spurts of fluid hit the back of his throat. Unsure
about what to do he just sat there and accepted it into himself. Hackmon knew
the consistency of semen was thick, but that knowledge didn't help to get it
down. Should he even be swallowing it at all? Of course this thought was in the
back of his mind too, but again, he was too lost in pleasure at the moment to
think straight.
Gulp after gulp he swallowed as much as he could before pulling back for air.
As he pulled away, what was left, which was a mixture of the twos bodily
fluids, dripped out of his mouth, soiling his partners lap.
After he got his breath up, he spoke. "Sorry, I'll clean that up."
"Was this your plan all along?" Rei asked between breaths.
"It wasn't, but perhaps this could be an efficient way to get you to come to
bed in the future."
Rei gently placed a hand on Hackmon's head. "I gotta admit. If this is what I
get every now and then, it'd be hard to pass up." Rei can't blame Hackmon for
wanting him to get a good nights rest every now and knows full well that he
tends to push his own body beyond its limits and how damaging it can be.
Tonight, Hackmon, more than ever, conveyed just how much he cares for his
partner. Rei felt that full force. Perhaps it wouldn't hurt too bad to spend
some nights like this, sleeping together with him.
