Hikaru appears to be a calm and reserved girl at first glance, but she actually has a slutty side. She gets wet extremely easily from any kind of stimulation—truly a total slut. While talking on the phone with a friend, she's secretly teased with a vibrator, and the excitement of pretending everything's normal while being stimulated makes her wetter and wetter. She also shows off aggressive solo masturbation with a vibrator, and although she pretends to resist when her anus is played with, her pussy is soaking wet. Her delicate reactions and the way she keeps getting wet despite trying to hold back are incredibly captivating.
