Mori Yuna is so cute that words fail—she has the face and voice of an idol and an endearingly innocent manner. This shoot gives her body a playful, intimate examination. Gentle Yuna accepts every request with a bright smile, spreads her legs in an M position to show her beautiful pussy, and lets it be measured before a vibrator stimulates her clit. After taking her baseline temperature, she begins masturbating. The action moves to the bed for deep foreplay, bare penetration, and creampie sex. When she sees what happened to the thermometer afterward, she simply flashes another adorable smile.
