adventures of steph and sam👯
(this is a work of fiction. all characters are consenting adults!!!
also, this is something new🤭 a lil dd/lg, md/lb, sibling fauxcest melting pot! shoutout to my bestie/baby brother @diaperedgalor for basically cowriting this hehe)
stephanie rolled over in bed, surprised to bump into something. no, not something. someone.
she sat up in her twin bed, squinting through the sunlight streaming in.
“sam. why are you in my bed again?”
her little brother sam was curled up next to her, taking up half her bed. he was 26, way too old to be crawling out of his crib at night and into her big girl bed.
stephanie gave her brother a rough tussle.
“get up. you’re taking up half my bed. and you smell like pee.”
sam didn’t wake, only snuggled in closer, nestling his head into his sister’s shoulder. he was warm and cozy like a heater, with his very soggy diaper and his dinosaur onesie keeping him snug. there he lay, blissfully sucking his paci and probably filling his diaper whenever he felt the urge.
unlike stephanie, sam was not potty trained at all. their mommy and daddy kept him diapered all the time, while stephanie only had to wear her diapers at night. a fact that stephanie was very proud of.
she relished her role as big sister, and loved that she was bigger and smarter and more independent than her baby brother.
but secretly, stephanie kinda liked how needy sam was. and she kind of liked that he smelled like pee as he curled up into her side.
stephanie gave her baby brother’s diaper an experimental grope through his onesie. her hand was met with warm, squishy padding. oh. sam was soggy.
the feeling of the swelled up padding made stephanie squirm, suddenly very aware of her own padding around her princess parts.
she reached a hand down to check her own diaper. just a little damp. daddy would be proud of her. out of their two parents, daddy was in charge of steph’s diapers, while mommy was in charge of sam’s.
they said it was “easier” but both kiddos knew it was actually because sam was mommy’s favorite and steph was daddy’s favorite.
just then, the door to the shared nursery swung open. mommy walked in, frowning at sam’s empty crib, then making her way over to stephanie’s bed.
“i see we had an escapee.” mom said, crossing her arms as she looked at sleeping sam. she shared a silly look with stephanie, and then said conspiratorially, “should we wake the silly baby or let him sleep?”
stephanie yawned, sitting up in bed on her knees.
“wake him!! he woke me by taking up my whole bed!!”
“steph, girly, i’m sorry sam intruded on your big girl space again. do you want me to move the crib into my room? it’s really no big deal.”
stephanie thought for a second.
“mmm, no mommy, it’s okay. i kinda like having my baby brother close.”
mommy chuckled. “of course you do, big girl.”
steph watched as mommy started to rub sam’s back, nice and slow at first, then a little bit faster.
“sammy?” mommy said into his ear. “wake up baby”
sam’s eyes flickered open and he blinked slowly, taking in the scene.
“mommy?” he said, his voice muffled through his paci. “why’m i in sister’s bed?”
stephanie rolled her eyes.
mommy laughed. “i was going to ask you the same question!! did you sneak out of your crib again to sleep with big sister?”
sam rubbed his eyes, still blissfully sucking his paci, half asleep. “maybe…”
stephanie rolled her eyes again. “you have your own crib. why do you hafta take over my bed?!”
sam reached out and hugged his sister. “because it’s more cozy where you are.”
stephanie couldn’t even be mad at that. she loved her baby brother, even when he drove her crazy.
while steph and sam bickered, mommy started to get the changing table ready, fluffing up a fresh diaper and getting all of the powders and creams ready.
“sammy, let’s change that night night diaper of yours.” she said, helping him sit up in bed and leading him to the table.
“mom? can i help with sammy’s change?” stephanie asked, watching with intrigue as sam laid down on the changing table, his legs instinctively going in the air to be changed.
“you can watch, sweet girl.”
that was good enough for stephanie. she perched at the end of the table, watching with wide eyes as mommy unsnapped sam’s onesie and revealed his diaper.
it was a miracle he didn’t leak all over stephanie’s bed. the diaper was full. it had swelled enormously, and now forced sam’s legs apart.
stephanie reached out to squish the diaper, but mommy batted her hand away.
“only mommy gets to change sam, remember?”
stephanie hmphed, but kept watching.
she watched mommy’s loving, practiced hands as they rubbed sam’s tummy, then gently rubbed the front of his diaper.
“someone was a super soaker last night, hmm? are you gonna need to be double diapered soon, mister?” mommy teased, making sam blush and squirm, covering his eyes with his hands.
stephanie watched, her hand instinctively going down to rub her own diaper.
mommy undid the tapes and opened up the diaper, carefully folding it in on itself.
sam lifted his hips obediently, and mommy slid the soggy diaper out from underneath him. she bundled it up and handed the squishy, warm bundle to stephanie.
“can you be a good helper and throw this in the diaper genie?”
stephanie froze, the used diaper in her hands. she could feel the warmth from it, the weight from sam’s pee. she could smell him all over it. and in that moment, she wanted nothing more than to touch herself through her diaper.
“steph! what are you doing?” mommy asked. “go throw it in the diaper genie, silly goose.”
stephanie blushed and obeyed, coming back to sit and watch the rest of the change.
her little brother was laying on his back, completely exposed and vulnerable. he was sucking on his paci, bare feet kicked in the air, little prince parts exposed and covered in pee and residue from the barrier cream.
steph couldn’t help but stare, enamored at her brother’s parts. the only other boy parts she’d ever seen were daddy’s, from when she had “special playtime” with him.
but she never got to touch sammy’s boy parts. and now she wanted to.
“mommy? can i help you wipe?”
mommy gave stephanie a knowing look. “not this time, sweet girl. that’s mommy’s job, okay?”
stephanie hmphed, but agreed. she was content to watch as mommy got a baby wipe and started to thoroughly clean up all of sam’s parts. every nook and cranny was gently, lovingly wiped clean. then, mommy leaned over and gave sam a special kiss on his parts.
stephanie wished she could see better as mommy’s mouth worked against sam’s skin. it didn’t last long, and then sam was whimpering and gasping and shaking into mommy’s mouth.
mommy swallowed and wiped her mouth, then kissed sam on the forehead.
“good boy, sammy!” she praised, tickling his sides a little bit.
he giggled and kicked, looking totally blissed out and giddy.
stephanie blushed seeing her brother like this. but she also felt a ping of jealousy.
sometimes daddy put his mouth on stephanie’s parts during a diaper change. sometimes he even undid his belt and took out his grown up part and put it inside her. that was her favorite type of change.
but now, she was still taped up in her night time diaper, and daddy still hadn’t come in to change her and say good morning.
she hmphed, and reached down to rub her diaper again, more frustrated this time. she couldn’t get any friction, nothing against her parts.
she made another needy sound, and then-
daddy’s voice suddenly came from down the hall.
stephanie practically squealed with excitement. she got up from the changing table and bounded across the room.
“hey you,” daddy said from the doorway, hands going under her armpits and easily picking her up. “good morning, my sweet girl. were you helping with sammy’s change?”
stephanie melted into daddy’s arms. she hadn’t even realized how much she had been missing him until he was holding her now.
she happily nuzzled into his neck.
“mhmm. sam was really soggy.”
daddy chuckled. “i bet. should we see how soggy you are?”
stephanie giggled. “i’m not that soggy, daddy!”
“you sure? should we check just to be certain?”
“maybeeee. just to be certain though!”
“good deal, kiddo. let me just say good morning to your brother.”
still holding stephanie, daddy walked over to the changing table.
“good morning lil guy.” daddy said, patting the front of the fresh diaper that mommy had just secured onto sam. “i heard someone was a lil soaker last night, hmm? guess we’re not ready for potty training, unlike your big sister here.”
sam giggled and squirmed. “daddyyyy. i like my diapers.”
“no one is disputing that fact.” daddy said. he gave sam’s diaper another pat, and then turned his attention back to stephanie.
“let’s free the princess from her padding, hmm?”
stephanie giggled and nodded. she loved mornings in the nursery like this.
just blissfully waiting for daddy to change her, hearing the soft giggles of sam, the gentle words of mommy, stephanie felt wrapped in love from all sides.
she smiled to herself, realizing she was in a kind of heaven.
