You could watch Yuki Mori take her clothes off and nothing more, and be done wanking.
She has never fucked machines and usually fucks in bondage, but today she gets the chance to be free and move her sexy body all over the bed while the machine follows her pussy, deeply fucking her. She cums hard - legs stretched out, toes clenched, body tight - and those light, high-pitched moans of pleasure are not to be missed.
She cums twice from the pounding, and then asks, "What is the Sybian?" It's a ride to the other side, as her clit takes on so much vibration, her whole body is humming by the time she peels herself off the machine.
