A cute but clueless, zero-sex-appeal plain girl was actually a super conservative sex monster that only I knew about… She had been hiding her pent-up sexual desires and they suddenly exploded onto me! Her usual self couldn't imagine such lewdness, making me incredibly excited with the hardest boner ever against this plain girl! The plain girl transformed into an ultra-slutty woman demanded my dick forcefully, and I ended up having crazy sex with her！！
