One day, Mizuki begs her, "I have no experience with sexual things between women, please let me practice with you." Meisa, unable to refuse, reluctantly agrees to practice cunnilingus, thinking, "If it's over our clothes..." However, Mizuki's cunnilingus intensifies, and the moment she licks her pussy directly, a shock runs through Meisa's body... Cunnilingus-focused! An intense oral lesbian sex where her pent-up love explodes.
