fiction, diaper, age gap
6 year old kitten at its first sleepover. Still having occasional nighttime accidents so it has to sneakily diaper itself in the bathroom before getting dressed in its pjs for the night.While the fleece bottoms hide the telltale bulge enough for its friends to not notice, there's no hiding it from the host's big sib, having had too much time as a babysitter.
The night goes on without any revealing incidents, other than a few waistband peeks. Come morning though, it groggily stirs awake in the big sibling's arms, being gently carried off to their room.
Still in a sleepy daze the entire time until the feel of a cold wipe pressing against its parts jolts it awake. Embarrassed mumbling shushed by a pawpad to the lips.
A soft explanation that they're only trying to save your reputation enough to shush it up for a bit, but still be a blushy mess on the makeshift changing setup on their bed. The most it manages to eke out is a 'Thanks' and an 'I'll do anything to repay you.'
Of course 'anything' to a hormonal teen only means one thing. Their paws working at the kitten's mottled canine cunny, working under the guise of making sure it cleaned every inch, before slipping their cock in. The cat too distracted by the weird feelings to even notice it being revealed.
While it's a tight fit and a bit painful at first without any proper lube or stretching, the pleasure eventually overrides. Squeaking as it feels the tip knocking at its cervix, unable to take the entire teenage length. The big sib too lost in horny lust to even care, just thrusting what it can without abandon while the rest of the house sleeps in.
After what feels like hours to the pair, but in actuality was more like 5 minutes, the teenager flops on top of the small cat as it feels something warm filling its core. Unable to move under the weight difference, just forced to take every drop.
After a few more minutes of afterglow and recovery its hastily redressed, not even any attempt to clean up the dripping fluids from its sore cunt before the duo get started on making breakfast.
The kitten mostly just standing on the step stool and watching while the teen does all the work, too young to really do anything in the first place and too distracted by the oozing down its thighs anyways.
The rest of the morning mostly going on in a daze, trying to figure out how to convince its parents to hire them as your new babysitter so that the whole thing wasn't just a one time occurrence…
