"If you can't enjoy sex, you're missing out on half your life," says Kaoru Teranishi, 38. A full-time housewife and the mother of two children, she has been married for 11 years. She is a friendly wife who brightens up the people around her with her smile, but behind her smile is a serious problem. Kaoru has a sensitive constitution that makes her cum the moment she penetrates. She is satisfied and calms down within a second of penetration, so she has to stay with her husband until he cums. She says that sex is always awkward when the timing of the excitement doesn't match. She wants to enjoy sex more. With that in mind, she volunteered to appear in the film, seeking overwhelming heat that doesn't cool down after one orgasm. Watch as this prematurely ejaculating wife, who climaxes with one thrust, rides the second wave of pleasure and aims for a sensual world she has never experienced before on this great adventure.
