Hope you guys enjoy this one! Diaper captions which focus on punishment are always a favorite of mine.

“Sis, Please!” I beg, desperately trying to hold in my mess. My sister watches with a giggle, phone out, recording. “I’m getting tired of hearing your begging. Just use that cute little diaper like the baby you are and maybe I won’t post the video if you do it quickly enough” She teases. Those laxatives she had given me earlier were working their magic on my bowels. I wasn’t going to be able to hold it much longer. “This is what you get for being a pathetic little pervert. If you dare try something like that on me, your own sister again… I might just force you into this permanently.” She explains, a dominant grin across her face as I struggle to hold in my mess A loud gurgling sound came from my stomach. I could only imagine how pathetic I looked on camera. Seconds away from messing my diaper, wearing a pink skirt and stockings. I really should have learnt my lesson a long time ago. But having failed to attract any girls yet, my oh-so hot sister was just too difficult to resist. I often found my eyes drifting towards her perky breasts, and perfect butt. Earlier today, it was just us in the living room. She was wearing a shorter-than-usual skirt for her. And when she bent down briefly, I took my opportunity to get a peak at something usually so out of reach. Her pretty panties tightly clinging to her butt. The sight caused my virgin dick to grow immensely hard within my underwear, creating a tiny but noticeable bump to the outside. It was great for all of 5 seconds… But then she realised. And that was how I ended up here. A mudslide of filth unloaded into the back of my thick pink diaper, as a few small tears spill from my eyes. The diaper grew heavy under the weight as I lost all control. The diaper grew visibly brown on the outside. Worst of all, every second of it was on camera. “After this, I hope you’ll think again before you start perving on me again, you pathetic little bitch” She says, smacking my messy diapered butt.

She was preparing to put me on. I was powerless as i watched as she stripped down to just her soaking wet diaper. I knew my fate was sealed. She tore off her soaked diaper, and i had to admit i was getting horny watching her wipe down her piss-soaked pussy. In spite of the diapers she was really good looking. She picked me up, sprinkled some powder and taped me up over her crotch. My front padding rubbed against her pussy as she moved, my body stretching to fit her movement. I absorbed her natural sweat as she moved, but i knew that wasn't the worst i would be subjected to. Her body odor overpowering me. This was clearly turning her on, as her pussy juices leaked out into me, as i unwillingly soaked it all up. She lay down in bed and soon got distracted, reading the internet on her laptop, as you can do nothing but lie there strapped to her crotch. She let out a large wet fart, giggling as she knew you were suffering as it was all trapped inside. But the worst was still to come. Just a couple minutes later, you were flooded with urine as she had an accident. She was clearly aware of it happening as she placed her hand over the front, squishing your padding right up against her pussy as she continued to relase her bladder out into you. Your padding unwillingly absorbed it all. The horrible, salty taste and the smell as well. She continued to rub your soggy padding up against her wet pussy, moaning loudly. "You make such a good diaper, lil bro" She teases. yet You began to hear her bowels contract and gurgle, and you soon realised what was coming, even if you hoped it wasn't the case. She didn't usually mess her diapers, but she was clearly about to make an exception for you. Her muscels worked as a couple more wet farts exploded out. WIth her pushing, soon large amounts of warm mess begin to pour out. It was even worse that with the piss. You sagged further from the weight as you were forced to hold it all there.
