Once upon a time, in a quiet corner of the world, there lived a girl named Yuuna Shiroboshi. Outwardly cool and reserved, she secretly craved endless affection from her master, behaving like an affection-hungry pet. With her translucent pale skin and soft, bouncy breasts that swayed with every move, she longed deeply for warmth and closeness at home. Her desire to be held and cherished by her master grew so intense that it gradually turned into something erotic. Just like a clingy little pet, she'd squeeze her breasts tightly, making them soft and slick, enveloping her master in pure sensation. As a reward, she'd give an erotic massage, wagging her cute tail and hips excitedly, trembling with pleasure, her eyes glistening with tears, whispering sweet, sultry words in a delicate voice. This intimate, affectionate playtime with the endlessly needy Yuuna feels like a thick, deep experience—one where her total devotion to her master becomes an unforgettable story.
