I can now hear the bitchy inner voices of my classmates! Various erotic voices! Voices wanting it! Voices of frustration! I can hear them all! If I torment that spot pinpoint accurately... I'm a non-standout, unpopular, air-like mob character in class. So having sex with girls at the top of the class caste is just a dream. The balls of a boy who was playing catch on my head hit me directly! I lose consciousness and collapse. And when I regain consciousness, I can hear the inner voices of the girls in my class? What is this? Hallucination? No, no, that's not it! This is their true feelings! No way? Those girls were thinking about such erotic things normally! That means if I initiate action at the timing they wanted with their inner voices... I can fuck them easily!? Sex is all about timing, isn't it? If I don't miss this, even I, who is unpopular, can become a fucker! By the way, since I continued to hear inner voices even after I went home, my step-sister and childhood friend also got it.
