Marino is a young woman who has just become a working adult, leading a serious life as a bank employee. However, driven by curiosity, she decides to appear in an AV. It's surprising how modest she seems in daily life, yet in bed reveals an unexpectedly erotic side! As we talk, she shares a story about once inviting two host boys for a business trip, resulting in a threesome experience—revealing just how curious and secretly lustful she really is. With a slender build and highly sensitive erogenous zones all over her body, her first encounter with a vibrator is adorable; she shyly places it against her pussy, slightly embarrassed. When penetrated from behind, she trembles intensely, giving excellent reactions. Her climax is especially intense—her whole body jerks powerfully, while she coyly hides her face in embarrassment, looking incredibly cute. Spreading her legs reveals her soaked panties, clearly showing her pussy is already ready and eager. Gently licking her wet, slippery slit, she sways her hair with soft moans of "Ah! Ahhn!" While fingering her, stimulating her pussy simultaneously with the vibrator sends her into repeated orgasms. Her tight pussy grips firmly around the cock upon penetration, and when thrust deeply and forcefully, she bucks her hips wildly. After multiple intense climaxes leaving her completely melted, the scene ends with a creampie on her stomach. Changing positions and locations throughout their passionate sex, this wild encounter was surely an enjoyable experience for Marino as well.
