Jay's P.O.V.
I sat on my bed where Liz had told me to wait as she went to grab some stuff from her car, wondering what exactly she was getting. My thoughts were cut short as I heard the front door open and shut, followed by the sound of Liz's feet on the hardwood floor, heading towards my room. She opened my door, carrying two large duffle bags, one in each hand. One I assumed had all the things she'd be needing to stay until she could get properly moved in. The other, I could only guess as to what may be in it, though I doubted it'd be a mystery long.
"Okay baby boy" she said, walking over holding a sheet of paper, sitting on the bed next to me before patting her lap. "Come here and sit in my lap, okay sweetie?"
I gulped, feeling a little embarrassed that she wanted me to sit in her lap, but I obliged, standing up and sitting on her admittedly rather thick thighs, feeling quite comfortable.
"Good boy!" she said, praising me as I blushed. "Now, while you're my baby there's gonna be a few rules for you to follow, okay?"
"R-rules? I-I get rules already?" I asked, feeling a little excited.
"Of course! Gotta make sure you behave yourself!" Liz teased, poking me in the side a little before starting to tickle me relentlessly, making me giggle and squirm. "Now, are you ready for your rules, baby boy?"
"Yes mommy!" I said excitedly.
"Good" she said as she smiled brightly at me with pride. "We're gonna go over the rules together and if you feel like anything needs to change, you let mommy know and tomorrow you get to decorate them, okay?"
"Okay!" I said as she held up the sheet of paper so I could read along, each rule wrote out in alternating blue, purple, and magenta marker.
"Rule number one: call me mommy. You've already been doing that without me asking so I think that one won't be much of a problem. When we're out and about you can call me by name, but otherwise it's mommy, okay pumpkin?" she asked, the little pet name making me smile.
"Yes mommy" I beamed with pride having already been good at that without realizing it.
"Rule number two: hygiene. That will mostly be my responsibility considering I'll be bathing you from now on, but you'll be getting at least one bath a day. Have you already bathed tonight, sweetie?" she asked, sniffing me a little, making me giggle.
"Yes mommy, I had a shower right after I got home" I said, smiling at her being silly.
"Rule number three, you'll be eating three meals a day. I know how bad you are about forgetting to eat, so I wanna make sure you're eating enough, okay baby?" she asked, kissing me on the cheek as I nodded in agreement.
"Rule number four is manners. Always say please and thank you. Manners cost nothing. And swearing, my little potty mouth, is a no-go from now on, understand?" she said with a teasing, yet serious look.
I knew I had a bit of a swearing problem, having been cursing for a good chunk of my life as my parents didn't really care all that much about the words, though I did censor myself in times I thought I needed to. I again nodded in agreement.
"Rule number five is your bedtime. I know you like to stay up late, but babies need a good night's sleep. From now on you will be in bed by ten. You don't have to go to sleep right away, but I want you asleep by twelve, okay baby?"
Another rule that was gonna be a bit hard as I was so used to staying up until two in the morning, but again it didn't sound like something that would be too hard to adjust to. "Okay mommy" I said with a smile.
"Good boy! Rule number six might take some getting used to, and if you're not comfortable with it we can get rid of it, but from now on I want you to use your diapers, okay baby?" she asked, looking at me curiously as I start to blush.
I had peed in my diapers multiple times before, finding the warmth filling them relaxing and comforting, but hadn't really tried to mess one before, feeling too scared of what it might feel like to even dare. Did she want me to do that?
"M-mommy does that mean I have to poop them too?" I asked, figuring it better to ask her and see if that was what she expected of me before committing to anything.
"Yes baby. Now if you really don't want to then I'm not gonna make you, but I wanna encourage it because babies poop their diapers, and I want you to be my adorable little baby. Do you think you can try it at least?" she asked, looking deep into my eyes, her expression making me feel like everything will be okay.
"Okay mommy, I'll try" I said as I snuggled into her shoulder, feeling my face heat up but wanting to make Liz as happy as she's making me.
"That's all I ask, baby boy," she said, kissing my head. Now I don't want you to sit in your used diapers for too long so you don't get a rash, so if mommy hasn't noticed you've gone, I want you to tell me. Also if you're not comfortable wearing them out of the house you don't have to, but I wanna encourage it, okay?"
"Okay mommy. Is that all of my rules?" I asked, looking up at her curiously.
"Yes baby, at least for now. If I feel like you need any more I'll add them later, but for now it's time to talk about punishments and rewards.
I gulped a little, having figured punishments would come if I didn't follow the rules. I didn't really want to be punished, but I knew if I was gonna be Liz's good little boy, they would have to be a part of it, so I nodded my head as she went over the punishments that would follow should I disobey.
After she finished going over the punishments and rewards she spun me around in her lap, hugging me tight and kissing my face repeatedly. "Alright baby boy! Now that we've gone over everything it's time to get you ready for bed! Hop up!" she said, bouncing her legs a little, making me giggle.
I look over to the clock, seeing that it's already 9:30 as I got out of Liz's....Mommy's lap. standing barefoot on the cold wood floor as she turned around and opened one of the two duffle bags, pulling out something I couldn't identify at first until she laid it on the bed. It was a navy blue onesie, decorated with colorful astronauts, rockets, stars, planets, and constellations. It was one of the ones I'd always wanted but shied away from buying. How did she know?
"Now, let's get these big boy clothes off you and get you into your pajamas, shall we?" she said, walking over to me and starting to tug at the bottom of my shirt. Getting the memo I raised my arms, letting her pull my shirt off over my head before she grabbed the waist of my pajama bottoms, starting to tug them down, stopping half way and sniffing a little.
"Well now, I wasn't expecting this so soon" she said in a bit of a sing-song tone as she pressed on the front of my diaper, making me realize I had wet it a little.
"Wh-what?" I asked blushing as I felt the still slightly warm damp padding press against my crotch. "Wh-when did I...?" I asked myself before realizing I must have peed a little when she tickled me.
"Well baby, before we get you changed into your jammies, I think you should finish using that diapee so mommy can get you into a fresh one." she said as she patted my damp crotch.
I'd been holding it since she'd got there and her encouraging me to use my diaper had made me focus on my bladder, realizing just how much I really needed to go. Blushing a deep red as I look at my girlfriend turned mommy, I gulped a little, before sighing as I let go, struggling a little at first but soon feeling the warm urine fill my diaper as I can hear a soft hissing sound. She stood there, watching as my diaper turned from bright white to pale yellow, she was smiling as I blushed deeply. Before long I feel the last of my pee trickle out as the hissing stops.
"That's mommy's good boy! So brave going pee pee in your diapee!" she said as she hugged me, placing her hand on my soaked diaper, feeling how warm and squishy my padding had become.
"Alright baby, I think you definitely need a fresh diapee before bed." she said before turning around, pulling another piece of fabric from the bag, laying it on the bed. It was a matching navy blue changing pad covered with the same colorful space pictures all over it. She then pulled a fresh diaper from the bag as well, followed by a box of wipes and a bottle of powder. The diaper was bright white in the middle with either side being dark blue with stars and colorful paw prints, the center having pictures of cats with space helmets, rockets, and fish skeletons. I was starting to see a pattern, knowing Liz knew how much I loved all things space.
"Come on now" she said, walking over to me, picking me up in her arms as I instinctively wrapped my legs around her waist. She was quite strong, though it probably didn't hurt that I'd never really weighed all that much and was a tad shorter than her. She laid me down on the changing mat, before starting to tug at the tapes of my diaper, making me cover my face with embarrassment as she pulled it open. "Aww, my baby's embarrassed at having his diapee changed for the first time" she said, a mischievous smile crossing her lips, not that I could see it for my hands as she reached down, starting to tickle my sides, making me erupt in a fit of laughter, laughing hard enough to insure I'd have peed myself if I hadn't already done so.
"Mawmyyyy, sthaaaap!" I said as I laughed, starting to feel myself slipping a little.
"Awww, sound like I got a little someone to slip!~ I'm sorry baby. Mommy couldn't resist. Feeling a little less embarrassed now?" she asked, looking down at me with a smile, making me blush a little.
"U-uh huh" I said, simply nodding my head a little.
"How old are we now, baby?" She asked, the question making me giggle as I held up two fingers. "Awww, I have a cute little two year old, huh?"
"Uh huhs!" I say happily past my paci.
"Good boy, now lift that butt for mommy!" she said, patting my hip a little as she took my paci and slipped it in my mouth which I immediately started sucking.
She grabbed a handful of wipes from the box as I did as I was told, lifting my butt up off of my soaked diaper so mommy could pull it out from under me, starting to wipe my wet butt with the wipe as she slid the fresh diaper under me after balling up the old one and dropping it on the floor before gently pushing my hips down onto the fresh, fluffy diaper, starting to wipe my privates, the cold wipes making me shiver a little, making mommy giggle.
"Aww, I know, the wipes are cold, aren't they?" she said, poking my belly
"Uh huhs! Deys cowd, mawmy!" I said past my paci, giggling a little as she smiled down at me.
"Well we're all done with the cold wipes now, baby" she said, starting to powder my crotch, lifting my legs to powder my butt as well before taping up my diaper as I continued to suck on my paci. She made me stand up and lift my arms over my head, slipping the onesie she'd laid out earlier over my arms and head before snapping it at the crotch and wrapping a blue strap decorated in rockets around the pacifier before clipping it to my onesie.
"Now, mommy's gonna go get you a bottle ready and then it's off to bed for you, mister" she said, pulling a large baby bottle decorated with rockets and stars from the bag after she was done putting away all the changing supplies, walking out of the room to go fill my bottle.
I couldn't help but look over in the mirror, seeing myself in the full baby outfit, pacifier in my mouth clipped to the onesie, my thick padding very obvious. I LOVED it. I walked over, looking myself up and down, thinking about how cute I looked. As I was looking myself over, mommy walked back into the room with a bottle in hand, full of milk.
"Aww, you like your new onesie, baby?" she asked, giggling as she made her way over to me.
"Uh huhs! I wuvs it, mawmy!" I said, smiling brightly past my paci
"Good" she crooned, giving me a kiss on the cheek before lifting me with one arm, carrying me to my bed. "Come on, baby boy. Time for your bottle then bed."
She climbed into bed, pulling me into her lap and cradling me as she lifted the bottle to my mouth, making my heart race as she pulled the pacifier from my lips. I opened my mouth, letting her push the nipple in as I latched down, starting to drink the warm milk from the bottle as she started rocking me gently. It was so relaxing I thought, more relaxing than I'd ever imagined as I felt my eyelids growing heavy, snuggling into Liz's chest, into mommy's chest, as she patted my butt gently to snap me awake enough to continue drinking my milk. Soon after the bottle was empty I was almost fully asleep as she laid me down and popped the pacifier back in my mouth, starting to suck it again softly as I drifted off to sleep.
"Goodnight my baby boy" she cooed as she kissed my forehead.
"Nini, mawmy. Wuv chu" I said sleepily.
"I love you too, baby" she said as I was out like a light.
