Hoshizaki Yuna, a big-titted girl, works live-in at an inn in a hot spring town. With her boyfriend away, she spends her days watching AVs and masturbating repeatedly. There are hints of secret encounters with the inn's owner. She applied for an AV audition because her daily routine had become too dull. Extremely sensitive, she gets wet just from dirty talk, climaxing over and over from handjob stimulation. She enjoys various positions like cowgirl and grinding, and grows even more passionate once penetration begins. Even after cumshot, she still looks ready to cum, pushing her pleasure further.
