Elf Arousal Challenge

Lily, an elf girl, has come to the human world in search of a "crush" that will make her heart all aflutter. Asahi, an ordinary school boy, tries play "grab the nipple" with Lily as a typical human game. Lily bragged that she would never fall for him with such a silly game, but the more he touches her, the more her cheeks flush and her breathing gets rougher… From a tsundere elf to a gloomy succubus and a dominant angel! A slightly silly harem love comedy that will thrill all races is about to begin!
