I was contacted by a manager I know, who told me that an actress who had been in AV for about two years under a different name had made a comeback. She said she really wanted to do bondage SM, so she asked me to meet her. So I met Kokoro-chan, and my first impression was that she was not quiet, but rather a dark girl with a shadowy side. To be honest, I don't dislike her. Kokoro-chan had had sex in her private life and in AV, and it felt good, but she had never been able to fully orgasm. Kokoro-chan said that she had been shy since childhood, was not good at interpersonal relationships, and that expressing her emotions was her worst skill. She was the type of person who always lived her life worrying about what others thought of her. So why did she go out of her way to do bondage and SM, even though she had no experience in private life at all? "I want to change myself, so I want to become a person who can express my emotions!!" This was the only thing Kokoro-chan clearly told me. At that moment, I decided to film her. I decided to film her, but she hadn't really exercised much up until now, and I thought it would be too much of a challenge to suddenly tie her up with hemp rope, so I decided to film her to see if she had a masochistic side! Mission 1 First, I decided to have her masochistically masturbate in front of a large crowd, which was perfect for Kokoro's personality, which is always concerned about what other people think. At first, Kokoro was nervous and embarrassed, and just laughed shyly, but when I touched her clitoris through her cotton panties, an erotic stain started to appear on her panties. The verbal abuse from there turned her on, and when I put my hand inside her panties and touched her directly, the lewd sounds of her pussy echoed through the room. Kokoro was able to masturbate in shame in front of a large crowd! The mission was a great success! The second mission was deep throat training hard blowjob. I heard during the interview that when Kokoro was doing AV before, the play that gave her the most sense of accomplishment was hard blowjob, so I attacked her quite hard. She was teased deep in her throat, and a thin stick was inserted into her, and she cried and vomited many times. Kokoro's suffering was so cute and fleeting!! She showed us her intense side in hard irama and throat-hole irama. Mission successful. The next mission was to restrain her genitals in an M-shaped position with handcuffs and leg irons on a platform. Kokoro became more and more erotic as the actors' persistent cunnilingus made her more and more erotic. When they dripped red wax on her halfway through the electric massager and vibrator torture, she cried out loudly and went wild! They made her hyperventilate! It was filled with the ultimate SM-like masochistic feeling. After all the filming was over and we went to the dressing room, Kokoro was very cheerful and said, "I've never cried so much in my life." Her face was full of a sense of accomplishment. This "M-test" was a great success! I'm looking forward to Kokoro's future challenges!!
