In this prank series, baby-faced adult gal Tsubasa Miyashita is promised a mistress contract with a wealthy company president, unaware that the man is actually homeless. She bathes with the foul-smelling “president,” who repeats his favorite periscope stunt, while the staff claims he invented the wand vibrator to convince her he is rich. His sexual experience and technique leave plenty to be desired, but Tsubasa works hard to please him and even accepts a creampie. Her reaction when the truth is finally revealed is the real payoff.
