On the surface she is an ordinary part-time housewife you can find anywhere. Her family and daily life look completely peaceful. But deep inside her there was an intense 'hunger' she had been suppressing for a long time. One day at her part-time job a 'secret hourly wage raise contract' is presented. Unable to resist the sweet temptation that lets her obtain both money and pleasure, she signs the contract behind her husband's back with the excuse of 'just once...' From that moment her reason melts away and a woman's instincts begin to run wild. Secret cheating sex. Thrust up by 151 consecutive intense pistons, the part-time housewife goes mad with orgasm and drowns in climax. She can no longer stop. She can no longer go back.
