Tsubasa, a budding model, visits a beauty salon, lured by the free offer.

She is pursued further while she is convulsing and climaxing, and even when she squirts, the salon doesn't stop, making her abdominal muscles twitch... Tsubasa thinks it's strange, but Tsubasa can't stop going to the salon as her career progresses...
