Kado Ona ... That unpleasant-sama! "Kaku masturbation" is established by pressing the genitals against the many "horns" and rubbing them against each other. It is said that this is also a trigger for sexual awakening, and a woman who has never masturbated feels pleasure when her genitals accidentally touch her horn and starts masturbating. Various stimuli that are different from the imagination will make them captivated by "horn masturbation".
