Ciel and Jeffy.

I met my special Jeffy when traveling between universes, an older woman had him as a companion. Her son had grown tired of him when he grew up and the android cub had never bonded. The lady explained that he could be more than a toy with love nd those bright blue eyes tugged at my heart. So I paid for him and took the little cutie with me. 
He was scared and I soon thought of why. "Jeffy, you did nothing wrong. YOu were a very good boy but She could no longer care for you well. Okay?"
He seems to process this as we travel in my small but comfy ship. "You sure?" He has the most striking eyes, A deep blue in his Fox face that seem to ask for nothing ore than love and trust. I rub his head and smile.
"She was getting close to dying and wanted you to be happy. SO I bought you because I love cubs and felt lonely. You can think of me as daddy. And I can even show you how to help me with the ship." I say to the android boy.
"Is that why mommy was sad? She was dying? I feel bad..." He says and looks at me.
"No need to be sad. I will care for you and love you. You like to cuddle and sleep with your daddy? I only have one bunk." I say and hug his small five year old sized frame.
"I love cuddlin'! One bunk is okay!" He says.
I chuckle and look him over and curiously undo the diaper. He simply smiles and I do it back up. "So...you can dress up like a girl too?" I ask.
He smiles that bright smile again. "And switch to a more feminine voice for you, daddy. If you want." 
I chuckle and hug him. "No just clothes is good. You are very cute as a boy and you don't have to change unless you want to."  He smiles and I chuckle at his cuteness. "So you are fully aware?"
He blinks. "No sir. That function has not been activated. Not all parameters were fullfilled."
I nod and set the auto pilot as I get up and look through all the upgrades and add on parts I bought. "Want to upgrade your power supply first? How long are you down to at top performance?"
"My charge will deplete in an hour sir." I nod and take the cute android's hand and help him onto the medical bed I bought. I open his chest panels and admire the nice work and love that went into making him. The boy must weigh nearly 100 pounds but his circuits are a work of art. I switch him to auxilliary power and get to work as i hear a faint giggle.
"Tickles? That makes sense. If it hurts I did something wrong." I smile and remove the old power core and carefully slip in the adaptor for the new one before pulling out the mini fusion cell and installing it. I decide to install all the sex ed programs that are meant to help him deal with cubs with older siblings and a few for the adolescence upgrade package but put those in stand by. I then start a basic chassis upgrade as he giggles cutely. I remove his old struts and replace them with newer stronger and lighter ones I look at his chest padding as i close him up and add some more just to give him a cute and softly feminine look or like a chubby boy. I close him up and reactivate all his functions.
"Hiya daddy. I feel a lot better now. But...I feel sluggish..." He gets up and I do notice he moves more like an adult than a young cub. "My servos are wearing out..."
I smile and hug him. “Aww…feeling old. You should feel fast and happy. We are near a port where we can get you more parts…new joints and stuff. And you have to be the cuddliest cub I ever hugged.” I scoop him up by his butt with a grunt and hold him like I would a son. “And your eyes are the cutest thing too.”
He seems to process this and gives a smile. “You really like me?” I notice that it seems more like programming than sentience to say “me” and “I” but I figure that may change over time. I boop his nose and he giggles.
“Yes, I really like you.” I turn and head to the cockpit, accidentally bumping his head. The response is immediate as he looks at me with a sad look.
“Why you hurt Jeffy?” He seems to tear up and even though I know it is automated I shush him and rub his head.
“Daddy is sorry. He forgot about that spot on the wall. Let me kiss it and make it better.” I kiss the spot on his head and he smiles slightly. “All better, son?” He nods and I tuck him into the co-pilot seat and buckle him in as I sit down and buckle myself in.
I set course for the port, picking a more casual approach to the landing before turning to him. “Hey Jeffy? Want to go on a ride? I could fly us down myself.”
“Um…well…never been on a roller coaster…I dunno…” He says and I smile and rub his cute head.
“Then we can take this one easy. We can have fun later.” I set an easy course and the small ship enters the atmosphere, shaking a little. He looks worried and even though I am sure it is just the interactive program I take his paw in mine and squeeze gently. “It will be okay son. Just a little shaking.” Soon the turbulence stops and I smile as the ship begins its automated landing. “See? No worries.” He smiles and I wit till we get near the port before taking control. The ship tends to bump hard when landing on auto so I guide it in and lower the power so it settles in easily with only a slight bump on the landing skids. 
“Jeffy, I will get you new parts to make you all better. Want to come? We can get some clothes on you. Oh and I need to upgrade the ships…defenses from bad guys.” I decide not to tell him that I have weapons built into the hull and in a turret. Although I had bumped his head on a fire control box added to help aim the guns. Also that is why half the ship is cut of, a few missiles take a lot of room and I had to remove the other cabin.
“Okay, daddy I can dress myself if you want. It is one of my functions.” He smiles that bright smile and I smile back and hug him. 
“But little boys are supposed to be dressed by their daddies.” I unbuckle him and get up and lead him to the cabin. I start sorting through the clothes I got with him and find a nice set of play clothes. I smile and begin by removing the old diaper and getting out a cloth one provided. I am not surprised he looks like a doll, he is one and kids don’t need anatomy lessons. I hum as I diaper him nd he seems to smile as I even add baby powder and then begin dressing him in the jeans and T-shirt. “Boots or shoes son?”
He thinks and shrugs. “I dunno.” I smile and get out some socks and some boots close to what I wear. I put them on and tie them for him as I get him a light jacket and then go to my synthesizer and guess at his hat size and put the hat made onto his head. “How do I look daddy?”
“Very cute and huggable.” I hug him and he giggles as I kiss his nose and boop it. I take his paw and lead the little boy to the hatch. I open it and wait for the look of wonder at the busy port. I almost frown when I see only a small one then remember that he is not fully conscious yet. I smile and lead him around the machinery carefully and to the port office. I pay the docking fee and head for the local market. “Get you new servos and other parts…and maybe some toys?”
“Toys, daddy? Hmmm…I dunno what toys I want.” He says as I look for a used parts dealer and find one that specializes in robotics and androids. We go inside and I smile at the look of thought on my little Jeffy’s face.
“You go ahead and think. I was going to get us some balls and maybe squirt guns.” I look around and find the proper parts. I decide to splurge and get the high performance models usually reserved for combat or acrobatic models. I figure the better he can move the happier he will be. I even find some high grade limb reinforcements that would fit perfectly. Jeffy watches and helps me carry the parts to the counter. 
“These parts are very expensive for a teddy toy sir.” The sales clerk sys as he rings up my purchases.
“Well I figured it would be best to upgrade fully and I want him to be at his best.” He shrugs and I pay for the parts and the cost of delivery. I smile and lead Jeffy out and down the street.
“Daddy…you really like me huh?” I nod and smile at him as I head for a small toy store. Jeffy holds my hand and looks around. “Can I gets a ball…um...a glove fer us both…” He thinks a he looks around.
I chuckle and get both a ball for outside and a small one for inside the ship as I grab an adult and child sized catching glove. I then grin and pull him with me over to the squirt-gun display. “How about some of these? You’re a good shot, right? I can be and love a good challenge.”
“Daddy I am programmed not to win…might upset a cub. But I do like to play.” He says and I grin as he grabs a simple yet pretty good model and I get one just like it. I head back and grab a basket to put the toys in and find some toy spaceships and cars.
“You know daddy doesn’t mind if you are better. It could help me improve a little. How about we get some foam dart guns too and then go back and fix you up?” He smiles brightly with those adorable glowing eyes and grabs both a pistol and rifle model. I grin and get some like them and then a big machine gun and foam rocket launcher. I also get the protective gear for the face and a set of foam melee weapons. After we pay I say, “Hey you can drink and pee right? So we can get some sodas?”
He nods and I set the toys to be delivered and I grunt but manage to pick him up and carry him to a small outdoor café where I order sandwiches and some sodas. “Daddy is it okay if I soil this diaper with the pee?”
I smile and kiss his cheek. “Isn’t that what little boys do? Have cute accidents, sometimes cry in embarrassment or just smile shyly as they do? I grew up kinda fast but I find little cubs like that cute. So if you want you can pee in your diaper sometimes instead of using a bathroom. I will grab a pack of thick cloth trainers so you can even go in bed and not wet it.” I smile nd he hugs me in response.
I eat as he drinks his sod, seeming to enjoy it, or maybe it was spending time with me he enjoyed? Hard to tell since I didn't check to see if he had taste buds. I eat happily and then say, "Belching contest, no speakers. Go." We both burp and i am surpried that he is able to make a perfectly cute burp, mine would have been louder anyway since the adorable android was cub sized. "So cute..." I trail off as he blushes and squirms. "Burping make your pee function trigger? I did that a few times at your age."
He nods and I drink my soda before taking him and changing him. Out of habit I use diaper rash cream, hving cared for cubs before. He giggles. "Daddy I dun need cream! Jus' powder to help dry!" He giggles and i chuckle as i add some powder and rediaper him. I set him down with a pat on the but and smile at the cute crinkle. We finish shopping and go to the ship.
