Femdom joi: A last-ditch effort to avoid a stepsister relationship

My stepsis issued strict Joi rules to avoid sisterhood. I balked, but she teased with big tits and a dildo. A game of mutual masturbation ensued, with her describing every touch and climax. A satisfying compromise.

In a desperate attempt to prevent a stepsister situation, I proposed a risqué challenge to my soon-to-be sibling. If she could beat me at a game of Monopoly, she'd be spared the fate of being my sister. To my dismay, she trounced me, leaving me with no choice but to give in to the reality of our new familial dynamic. But before we delved into our new relationship, she had a tantalizing proposition. She instructed me to pleasure myself, guiding me through every stroke and flick, all while a stunning mommy figure watched over us. The instructions were explicit, the pleasure intense, and the sight of her approvingly stroking her own ample bosom only added to the eroticism. The game had barely ended when the carnal instructions began, and the line between stepsister and lover blurred. The game may have been won, but the real pleasure was just beginning.
