Mari is a schoolgirl with a slender body and a model-like figure. She has a bright and serious personality and is usually an honor student, but Kokoro inside she has a desire to do naughty things with an adult man. She is invited to the house of an older man she met on social media, where she is forced to cum with a vibrator, deep-throated with saliva, and filmed in a passionate manner that almost breaks her delicate body. She also happily engages in soap play, which she "has always wanted to try." This is the erotic growth record of a beautiful girl with beautiful legs and black hair who looks great in a uniform.
