Daremo ga Urayamu Tonari no Cool Bishoujo, Jitsu wa Nounai Pink Sugiru

Whenever she appears in the classroom, she steals everyone's gaze. What's more, she has excellent grades and outstanding athletic ability—the perfect, cool, and beauty, Rio Kagura. However, sitting next to her, I, Sumito Yomine, secretly a telepath, am the only one who knows the truth. "Even though I'm being toyed with by multiple people, my body can't resist... this is so good." What she's reading at her desk is actually a (pretty hardcore) erotic novel! And during math class, she has the worst associations like, "That teacher totally looks like he'd be the male porn actor..." or during PE, looking at the other girls, "Her boobs are so big. I want to grope them from behind." Kagura's mind is always way too lewd! She doesn't get intimately close to anyone, but for some reason, she opens up to me and starts closing the distance between us!?
