In her mid-40s, married woman Hiromi Oya appears dressed in a sailor uniform. Recalling her days as a junior high and high school student when she wore the same outfit, she relives memories from her youth as if she's traveled back in time, indulging in creampie sex. Back in high school, she would leave home saying "I'm off!" and ride her bike to her boyfriend's house, where they'd have sex immediately—revealing she was highly sex-driven even then. Her body is extremely sensitive; passionate kissing and nipple play quickly soak her shaved pussy. Once fingered, her wetness flows steadily, and further stimulation causes her vagina to tighten. Penetrated with an erect cock, she cries out in pleasure, riding him in cowgirl position with loud, authentic moans. Since Hiromi never used condoms back in school, she eagerly takes deep, bareback thrusts until a hot, generous load of cum fills her deeply, culminating in deeply satisfying sex.
