After checking Black Panty Girl's underwear, the results were: stains ●☆☆☆☆, odor ●●●●☆, dirt ●☆☆☆☆, wear level ●●●☆☆, with a wearing time of 12 hours. The notes mentioned she wore a dark brown bra. This time, we met a Black Panty Girl whose panties resembled a gym short. We met up after her classes, and the girl who appeared at the location had long black hair and looked very serious. Her speech was polite for a young girl, her skirt length was modest, and she gave off a pure, innocent vibe. Since standing around wasn't ideal, we quickly moved to a hotel. She belongs to the track and field club, specializing in sprints. Her underwear had a sporty design typical of athletic girls, and the moment I saw it, I was surprised, thinking, "Isn't this just like a gym short?" The fabric had a smooth, airy texture similar to Airism, and when I sniffed closely, I could faintly smell detergent. After checking her bra, I found she was wearing a burnt umber-colored one with a swimsuit-like design. It was wire-free, designed not to leave marks and resistant to shifting—her preferred choice for track practice. Seeing such rare lingerie on both top and bottom was a real treat. After the inspection, we moved on to sex. Despite it being her first paid encounter, she was surprisingly open to dirty acts and licked me carefully. She was highly sensitive and very enjoyable to tease. Being a serious student, she kindly agreed to have sex in her school uniform. She happily rocked her hips during sex, suggesting she might secretly be a total pervert who loves dirty things. Proof of that? She was delighted when I creampie'd her. Since we still had time before our scheduled end, we moved to the bathroom after sex. She changed into a skimpy swimsuit so sheer it made her nipples visible, and we took a bath together. I then gave her a toy and watched her masturbate right in front of me. Wanting to see her naked body again, I had her strip once more and give me another blowjob.
