The sales manager at a mid-sized textile trading company continues to improve his business performance and has been promoted at an unusually young age. There are constant rumors that he is good at sleeping with his wife... The desirable wife with beautiful breasts is overworked in SM training for business entertainment, and at night she is tied up by her virile husband and subjected to sexual training. Big breasts are spanked, her crotch is roped and her nipples are teased with a brush, fingering and a vibrator is used on her wet hole, she is tied up and gagged and cunnilingus is exposed, she is forced to deep throat and cum in her mouth, and she is tongued with a nine-tailed whip and hot candle. Her reaction is so good that the client's executive plans to kick out her husband and make the masochistic young wife his personal mistress and female slave.
