nsfw babble (chastity, incest (transfem lil sis/cis big sis), messy diaper)
Back to Diapers, SquirtGetting bullied back into diapers every time big sis has to babysit you. Slowly teasing your little girlcock each time you use your diaper like a good girl. In a horny needy daze, you agree to do anything in order to finally get off.
Of course anything means having to convince your parents to put you back in diapers full time. With your bits locked up snug for security, you're on your own on convincing them.
Getting nighttime padding isn't too difficult, just a few nighttime 'accidents' is enough for you to come home from school to a plastic sheet on your mattress and a pack of goodnites on your pillow.
You beg your sis to give in, that that's enough. And you think you do when she retreats to her room.
But all you get is half an hour of fruitless wand time through your nighttime pants capped off with a coo of 'daytime too, squirt.'
It takes a month until you're pent up enough to go further, supplementing your now actually accidental bedwetting with a bit of water down the front to force leaks.
The goodnites quickly replaced with a case of the same diapers your big sis started off bullying you into albeit a tad thicker due to the nighttime variety.
While it's still not enough for your sis, it is enough for your horny-fogged subconscious to help move things along more.
The next family breakfast, sat at the table in just a tee and your soaked diaper as you much your sugary cereal, you finally hit your breaking point. The normal morning urge hitting on queue, subconsciously starting to standing up to use the big kid potty but stopping part way.
A soft whine sneaking out as your fogged mind decides to push, eyes scrunched shut in an obvious potty face in front of your parents and sis.
Big sis saying she'll deal with it so they can talk.
Unable to squeak out a word, you're drug off to get changed and cleaned up.
By the time you've been bathed and padded back up in something out of her babysitting stash, your parent's have decided to write it off as a fluke.
It takes another month of occasional daytime accidents, getting sent home from school with wet pants, pushing while padded for dinner, a puddle in your seat during a car ride, before they decide to have a talk.
Sat down on a puppy pad while they talk at you, telling you that you're going back to diapers as they can't afford to keep leaving work to pick you up from class, the extra laundry loads, and to save you from more embarrassment.
And just to make sure you're staying padded, your big sis is forcibly put in charge of them. A huffy grumble coming from her at those words, trying to mask that this was her intent all along.
It isn't for another week before you two are trusted home alone for the weekend.
Your cage quickly getting unlocked during your morning change, giving you a few hours to de-atrophy before she gives you what she's promised, though definitely not how you expected.
Laid down on the mat for your nighttime change, distracting you with lots of gropes and rubs to your full padding.
The cool air over your needy length breaking you from your diaper-brained thoughts long enough to see your big sis completely nude above you. The cold air only lasting a second before you're completely taken into her slick slit.
The smell of wet diaper and powder quickly mingling with her scent.
Cumming weakly almost on the spot as the aromas swirl around your sinuses, but she doesn't stop riding you until she's sated. Every drop you've been forced to hold in milked out into her. Quickly passing out in the post-orgasm cuddling afterglow.
Waking up the next morning in your bed to the familiar strain of your cage and a note on your bedside table.
'If you want that again, you've got to go further, squirt.'
Confused as to what she means by 'further' until you put down the note and see an oversized pacifier you overlooked.
Oh…
