A woman's sexual desire can sometimes be even more intense than a man's. Many will understand this after hearing Mari's story. Ever since middle school, she's viewed the world through lustful eyes—so much so that during class, she'd practice jerking off by pretending her mechanical pencil was a penis. While her classmates were still too shy to talk about sex, Mari openly used vulgar language with confidence, leaving everyone around her stunned by her boldness. Naturally, she was extremely popular with boys. She wore her skirt shorter than anyone else, flaunting her sexy body without hesitation. But Mari wasn't just another slut. Even while fantasizing about dicks with her pencil, she diligently took notes and consistently ranked among the top ten students in her grade. She carried this lifestyle into high school, still waiting for her first time. For someone who had perfected both her sexuality and academic performance, choosing the right partner was crucial. The man she set her sights on? Her homeroom teacher, a man in his third year of teaching. Three months after developing feelings for him, she confessed after school—only to be unexpectedly rejected and even scolded. This rejection changed everything. Mari decided she'd no longer be picky about her first partner. Instead, she chose a quiet, short underclassman. Why? Because she didn't want to be used and discarded during her first experience. With her strong desire to dominate, she planned to take out her frustration by sexually tormenting this younger boy, bringing him pleasure just to control him. But the underclassman surprised her—during sex, he revealed a fiercely dominant side, completely reversing their power dynamic and capturing Mari with his skillful techniques. From that point on, they stayed together until graduation, and Mari was ultimately trained into a full-fledged masochist. After college, she worked aggressively at a foreign company, where results and numbers came first, and employees pushed forward ruthlessly to meet targets. The workplace stress, combined with her known sharp personality, caused men to keep their distance. With frustration building up, she eventually decided to appear in this video. Mari's libido and passion for sex have never faded since puberty. See for yourself the lewd acts she'll expose in front of the camera.
