My girlfriend is a tsundere girlfriend! Yui is usually spunky, but suddenly she becomes a spoiled brat! ``If you want to have sex, I can do it for you.'' ``We promised to cum together, so why did you cum first?'' Both the tsun Yui and the slutty Yui love sex! Together with Yui, who is slender and has beautiful breasts, 24 hours a day! Unlimited sex! Completely subjective flirting with Yui Kimikawa
