As the title "My Research: The Prim and Proper Beauty Is a Secret Pervert" suggests, the seemingly pure and innocent Miku turns out to be a total pervert. Though she shyly asks, "What are you filming!?" she quickly slips into full pervert mode with just a little stimulation. Despite having no boyfriend, it's revealed she's already had sex with eight guys. Just touching her ears makes her hypersensitive, and with a small vibrator and some kissing, her pervert switch flips on instantly. Before you know it, she's grinding her crotch against the cock, completely transformed into a slut. This contrast is incredibly hot. She wets herself so much she soaks the sofa, and the sight of her blissfully sucking cock is even more erotic than you'd imagine. The way she begs, "Cum inside me!" while getting pounded is an unexpectedly perverted highlight. When she insists, "I'm not a pervert!" it only makes your heart race even more.
