Maruta W, a seemingly innocent Japanese wife, is introduced to the world of NTR by her husband, Maruta H. In the comfort of their home, he coaches her through the art of seduction, his words both degrading and arousing as she opens her legs for their friends. The room fills with the sounds of her pleasure, her moans echoing as she's pushed to climax after climax. Maruta H, proud and dominant, watches as his wife is transformed into a cheating, orgasm-ridden slut, her body no longer her own.
