We take an AV actress into our home in her private time and secretly film all of her natural expressions! Usami Mika(20) comes in without knowing anything. "Close the bathroom door!" In the atmosphere of a brother-sister fight, he regrets entering the room, saying, "Why did I come here...?" He forces his girlfriend, who is half-conscious from sleepiness and alcohol, to sleep with him. "That's not what I meant..." he whispers to her, "I'll forget about it soon..." and we make a contract and enjoy her brown bare skin. This is the raw, real SEX in a completely off-mode that you would never see on a regular AV set!
