Yuma Sano is a breathtaking married woman with a model-like figure, long legs, and F-cup breasts. She works in sales for an IT startup and privately admits that she sometimes uses her feminine charm to boost her numbers. Her husband is passive and rarely asks for sex; even when they do it, he often loses his erection before she is satisfied. Crushed by work stress and sexual frustration, she finally volunteers to appear in porn because she desperately needs excitement.
