A porn actress is brought to a man's home, where hidden cameras capture every unguarded expression. Twenty-year-old Mika Usami arrives with no idea she is being filmed. “Close the bathroom door!” Their bickering sounds like a squabbling adult brother and sister, and she soon regrets coming. Drowsy and drunk, she is nearly passed out when he forces himself into bed beside her. When she protests that this isn't what she came for, he whispers that she will forget it soon. She gives in on the condition that he keep it secret, and he uses the deal to enjoy her tanned bare body. The hidden cameras record raw private sex and her completely off-duty expressions—something never seen on a porn set.
