In class, she was neither conspicuous nor fashionable. Yet, she had a dark and sticky aura about her. One day, this gloomy girl asked me to teach her. When I went to her house to tutor her, she suggested we watch AV together. Apparently, she was a hardcore AV otaku. As we watched the AV she recommended, the atmosphere became strange, and she looked at me with a lewd expression, causing me to get fully erect... The gloomy girl, who wanted to have sex despite having no experience, used me as her experiment! I was fucked by this hidden big-breasted girl with insatiable sexual desires!!
