adventures of steph and samđŻ
(this is a work of fiction. all characters are consenting adults!!!
also, this is something newđ€ 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.
âsam. why are you in my bed again?â
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.
âget up. youâre taking up half my bed. and you smell like pee.â
sam didnât wake, only snuggled in closer, nestling his head into his sisterâs 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 brotherâs 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 stephâs diapers, while mommy was in charge of samâs.
they said it was âeasierâ but both kiddos knew it was actually because sam was mommyâs favorite and steph was daddyâs favorite.
just then, the door to the shared nursery swung open. mommy walked in, frowning at samâs empty crib, then making her way over to stephanieâs bed.
âi see we had an escapee.â mom said, crossing her arms as she looked at sleeping sam. she shared a silly look with stephanie, and then said conspiratorially, âshould we wake the silly baby or let him sleep?â
stephanie yawned, sitting up in bed on her knees.
âwake him!! he woke me by taking up my whole bed!!â
âsteph, girly, iâm sorry sam intruded on your big girl space again. do you want me to move the crib into my room? itâs really no big deal.â
stephanie thought for a second.
âmmm, no mommy, itâs okay. i kinda like having my baby brother close.â
mommy chuckled. âof course you do, big girl.â
steph watched as mommy started to rub samâs back, nice and slow at first, then a little bit faster.
âsammy?â mommy said into his ear. âwake up babyâ
samâs eyes flickered open and he blinked slowly, taking in the scene.
âmommy?â he said, his voice muffled through his paci. âwhyâm i in sisterâs bed?â
stephanie rolled her eyes.
mommy laughed. âi was going to ask you the same question!! did you sneak out of your crib again to sleep with big sister?â
sam rubbed his eyes, still blissfully sucking his paci, half asleep. âmaybeâŠâ
stephanie rolled her eyes again. âyou have your own crib. why do you hafta take over my bed?!â
sam reached out and hugged his sister. âbecause itâs more cozy where you are.â
stephanie couldnât 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.
âsammy, letâs change that night night diaper of yours.â she said, helping him sit up in bed and leading him to the table.
âmom? can i help with sammyâs change?â stephanie asked, watching with intrigue as sam laid down on the changing table, his legs instinctively going in the air to be changed.
âyou can watch, sweet girl.â
that was good enough for stephanie. she perched at the end of the table, watching with wide eyes as mommy unsnapped samâs onesie and revealed his diaper.
it was a miracle he didnât leak all over stephanieâs bed. the diaper was full. it had swelled enormously, and now forced samâs legs apart.
stephanie reached out to squish the diaper, but mommy batted her hand away.
âonly mommy gets to change sam, remember?â
stephanie hmphed, but kept watching.
she watched mommyâs loving, practiced hands as they rubbed samâs tummy, then gently rubbed the front of his diaper.
âsomeone was a super soaker last night, hmm? are you gonna need to be double diapered soon, mister?â 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.
âcan you be a good helper and throw this in the diaper genie?â
stephanie froze, the used diaper in her hands. she could feel the warmth from it, the weight from samâs pee. she could smell him all over it. and in that moment, she wanted nothing more than to touch herself through her diaper.
âsteph! what are you doing?â mommy asked. âgo throw it in the diaper genie, silly goose.â
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 couldnât help but stare, enamored at her brotherâs parts. the only other boy parts sheâd ever seen were daddyâs, from when she had âspecial playtimeâ with him.
but she never got to touch sammyâs boy parts. and now she wanted to.
âmommy? can i help you wipe?â
mommy gave stephanie a knowing look. ânot this time, sweet girl. thatâs mommyâs job, okay?â
stephanie hmphed, but agreed. she was content to watch as mommy got a baby wipe and started to thoroughly clean up all of samâs 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 mommyâs mouth worked against samâs skin. it didnât last long, and then sam was whimpering and gasping and shaking into mommyâs mouth.
mommy swallowed and wiped her mouth, then kissed sam on the forehead.
âgood boy, sammy!â 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 stephanieâs 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 hadnât come in to change her and say good morning.
she hmphed, and reached down to rub her diaper again, more frustrated this time. she couldnât get any friction, nothing against her parts.
she made another needy sound, and then-
âwhereâs my giiiiiiirl?â
daddyâs voice suddenly came from down the hall.
stephanie practically squealed with excitement. she got up from the changing table and bounded across the room.
âhey you,â daddy said from the doorway, hands going under her armpits and easily picking her up. âgood morning, my sweet girl. were you helping with sammyâs change?â
stephanie melted into daddyâs arms. she hadnât even realized how much she had been missing him until he was holding her now.
she happily nuzzled into his neck.
âmhmm. sam was really soggy.â
daddy chuckled. âi bet. should we see how soggy you are?â
stephanie giggled. âiâm not that soggy, daddy!â
âyou sure? should we check just to be certain?â
âmaybeeee. just to be certain though!â
âgood deal, kiddo. let me just say good morning to your brother.â
still holding stephanie, daddy walked over to the changing table.
âgood morning lil guy.â daddy said, patting the front of the fresh diaper that mommy had just secured onto sam. âi heard someone was a lil soaker last night, hmm? guess weâre not ready for potty training, unlike your big sister here.â
sam giggled and squirmed. âdaddyyyy. i like my diapers.â
âno one is disputing that fact.â daddy said. he gave samâs diaper another pat, and then turned his attention back to stephanie.
âletâs free the princess from her padding, hmm?â
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.
