A mischievous step-sis, desperate for attention, pushes her limits, accidentally letting go of her bladder while taunting her stepbrother. Humiliated, she expects a scolding, but instead, he takes in her damp panties and decides to teach her a lesson. He strips her, smacks her ass, and slides his thick cock into her tight, soaked cunt, pounding her relentlessly in doggy style until she screams in ecstasy, her pussy clenching around him as he fills her with his hot cum.
