I'm the only one who knows that this cute, plain girl with zero sex appeal is actually a super slutty sex monster who doesn't realize her own charms... All the pent up sexual desire that she'd been hiding and unable to release until now suddenly exploded and hit me! I was so excited by her eroticism that I couldn't imagine it from her usual appearance that I had the most rock-hard erection in history with a plain girl! The plain girl suddenly turned into a super slutty woman and forced me to have sex with her!
