I can’t believe this just happened… I was so excited to show off my new tight little shorts, feeling sexy and playful as I admired how they hugged my curves. Twisting and turning in front of the camera, I loved the way they looked on me. But then, out of nowhere, that sudden urge hit me—I really had to go. I tried to hold it, crossing my legs, pressing my thighs together, doing anything to keep it in. But my step-brother was in the bathroom, and no matter how much I wait, he wouldn't come out. I struggled, biting my lip, squirming as I fought against it, but my body betrayed me. A warm rush spread through my shorts, darkening the fabric as I gasped. I couldn’t stop it. The sensation was overwhelming… and strangely, so was the thrill.
