Couldn't resist my stepsister in yoga pants while parents were away

While our parents were away, I found myself alone with my stepsister. As she stretched in yoga pants, her curves accentuated, I struggled to resist the allure. The tension between us crackled, igniting a forbidden desire. With every movement, her body teased me, tempting me beyond control. Unable to resist any longer, I closed the distance between us. Our lips met in a heated kiss, a culmination of months of suppressed attraction. In that moment, morality blurred, replaced by the primal need for each other. It was a forbidden passion.
