Pale-skinned seductress Mio Futaba welcomes an adult friend who has come looking for her son Ken. Hearing that his girlfriend refuses to have sex, she offers to teach him herself. Mio gives him hand, foot, and oral stimulation, then lets him finger her wet before pulling her panties aside for bare doggy-style sex and a finish in her mouth. Her appetite is nowhere near satisfied, so they move to the bed and begin another round of intense sex.
