Unintentionally penetrated and filled with cream by my stepsister instead of my usual sex toy

I was trying to get my fix of some hot sex with my sexdoll, but things took a wild turn when my stepsister walked in. She joined in, and the action got intense and messy. Her moans and curves drove me wild, and I gave her the rough doggy style she craved. Ending with a satisfying load inside her, it was a crazy taboo encounter.
