She kneels before the mechanical dildo, her lips parted, her tongue flicking across her lips as she anticipates what's to come. The dildo hums to life, and she takes it into her mouth, moaning as it fills her oral cavity. She slides it in and out, deepthroating it with ease, her tongue swirling around the tip. She reaches down and begins to rub her clit, her hips grinding against her hand as she sucks the dildo harder. Suddenly, the dildo begins to thrust on its own, in perfect rhythm with her moans. She gasps as it hits the back of her throat, her gag reflex kicking in. But she doesn't stop, instead taking it deeper, her lips stretched around the girth. Her hips buck against her hand as she comes, the dildo still pounding into her mouth.
