My little sister is so cute...
The poor little thing, dressed up in her frilly onesie, soaked diaper sagging between her thighs and straining against the confines of her onesie. She tugs at my arm, eyes pleading for a change. I sigh. She's always so needy, so dependent on her big sis and 'Mommy'. I take her hand and exasperatedly lead her back to our room, her diaper rustling and audibly squishing as we walk.
Mom's late coming home, might as well take her through her nightly routine. I push her back onto the bed, shushing her with her oversized pacifier. I hop up onto the bed behind her, taking her cuffs and securing her wrists behind her back. Oughta keep her fussy hands out of my way. Off the bed I go, ordering her to lay back and spread her legs. My furrowed gaze deftly avoids her big watery eyes as I pop open the buttons of her onesie.
I take out my phone to snap a picture, her blush igniting behind the shield of her pacifier.
God.... she's so cute. Her diaper is so wet... I can't help but knead at the sodden padding, feeling the warmth of her pee permeating through the diaper. The smell is almost intoxicating, clinging to my nostrils, making my head fuzzy. Her diapers, themed after her favorite little plush toy that lays to her side on the bed... I can't help but kneel, lowering my face against her crotch, nuzzling in and breathing deep. Her scent, pungent and slightly sweet, wreaks havoc upon my senses. My nose brushes against her leak guards, I can't get enough.
She whimpers into her pacifier.
My mind is cloudy, skin burning with arousal. My mouth opens, i breathe heavy and hot against the cloth backed padding. A burst of warmth grows against my moving cheek, and it takes all of my willpower not to bite down on her diaper, at her naughty bits beneath.
I compromise by biting at her thighs. She yelps, struggling a bit but with her arms bound there's not much she can do. With my teeth, I untape her diaper. One tape at a time rips off of the landing strip, and I pull open the diaper to get hit with the divine scent of her pee. The saturated diaper is laid out under my chin, and once again it takes all my strength to not get in there and clean off her princess parts with my tongue.
I have to be big, I have to be strong, I gotta stay focused.
I clean her up with wipes, lovingly warming them between my hands before wiping her down. I remove her sodden diaper, rolling it up and setting it to the side before unfolding another diaper for her and sliding it under her butt. By this time, her arms have gotten tired, so I have to unbind her. Gotta be a good big sister and take care of the baby's needs, after all. She has the gall to pet my head as I finish changing her.
Soon enough, she's all taped up in another one of her 'boyfriend's' diapers, that damned little plushie finding it's way into her arms once again. With a kiss on the forehead, I settle her down for a nap, taking her balled up diaper with me as I leave the room.
My breathing is heavy as I sprawl across the couch. Her balled up diaper is still in my hands, and I can't help but lift the edges of it to my nose to breathe in deep of it. The pee inside is rapidly cooling, but I don't care. It doesn't matter. My hands set the diaper to the side before I fumble with the waistband of my pants, tugging them down to my thighs so I can better grope at my own soaked diaper. Her diaper is back up against my nose again, resting on my forearm at an awkward angle as my hand, holding my phone, shakily opens up my photo gallery.
There she is on my phone, those sheepish, dewey eyes, her soaked diapers...! My free hand finds its way down the waistband of my diaper, fingers rubbing at my aching bits. She's so cute, she's so cute...! Her scent fills my nose, her diaper and picture fill my vision, my skin is burning, my body aches, my hand moves frantically and I-!
Arch!
Time seemingly stands still for a moment, my body twitching as thunder takes me. My muscles relax. I feel wetness splashing against my hand.
It's not enough.
My hand moves again, my nose dives into the leg guards of the diaper, my phone falls to the ground, I don't need it anymore. She's all that prances through my mind, her and her almost leaking dia-
Again! Muscles tense, eyes squint shut, a whimper leaves me this time.
It's not enough!
Three, four, five more times. My diaper is a sodden wreck. Her balled up diaper is half untaped from how rough i'd been with it. The living room reeks of piss and sex.
It happens while I'm almost to my sixth orgasm. The front door opens. There's no hiding the mess I've made of myself.
Chances are, she already knows.
