I just found out my sister Shanice was texting my boyfriend pictures of her boobs behind my back. What a slut! I thought we were supposed to be family!! She is on her way home from a long drive and I know how small her bladder is, so I decided to wait for her at the door to the house and block her from coming inside to use the bathroom. She has to go so bad she almost immediately wets herself through her pants on the front porch, while our neighbors are out! She is whimpering and begging me to let her inside, but I just stand and laugh at her until I'm satisfied. I eventually let her inside but I'm not done with her yet, she was flirting with MY boyfriend! I need more revenge than wet pants. So I drag her into our little sisters room and make her let me put her in one of her diapers, she is super resistant but agrees when I threaten to tell mom and dad she peed on the front porch, they would be so mad. It's hilarious watching her struggle and be a major brat while I diaper her and ridicule her for wetting her pants earlier. I even take photos to use for blackmail, maybe I will send them to my boyfriend, he won't like her after that! I put a hitachi on her and make her cum in the diaper before leaving her to crawl out of the room still padded and super embarrassed.
