The smarter and more serious a woman is, the more she thinks, "I mustn't think dirty things..." or "Dirty things are no good..." In other words, she already understands what's dirty, and she's a bundle of pent-up frustration. You get it, right? That kind of woman is a total slut. Let's go all out and fuck her senseless! This work features two intense sex scenes with blonde Ema and the black intellectual Stone Misty, depicting how serious women unleash their hidden sexual desires.
