Mirai has experienced finger penetration with her boyfriend, but due to intense pain, she gave up on sex, leaving blowjob as the limit of her sexual experience. Now, for the first time in front of the camera, she reveals her body—her large, shining breasts standing out against her fair skin, her nipples glowing pink. This is her first experience with actual penis insertion. How she feels in that moment, her facial expressions and reactions are the highlight. With this being her first time, her face reflects a mix of tension, anxiety, and anticipation.
