Working at a lingerie shop, Kana-chan proudly showed off sheer, revealing lingerie for the shoot. Her body is just as sexy as the lingerie she wears, captivating anyone who sees her. However, she's a bit insecure about her chest, which is why she agreed to undergo breast enhancement massage. Her shy, embarrassed expressions during the massage only make her more tempting. Next, using a vibrator, her nipples are intensely stimulated, and her growing pleasure becomes unmistakably clear. When the vibrator is moved to her groin, she writhes uncontrollably, her body convulsing from the overwhelming sensation—eventually whispering, "I came..." She recalls her first such experience was with her younger brother's friend. He often came over, and since they'd known each other since childhood, Kana-chan was close to him too. That day, they were playfully fooling around as usual, but when he climbed on top of her, she noticed he was aroused. Pointing it out, saying, "You're hard," he denied it—so she stubbornly pulled down his sweatpants, only to find he wasn't wearing any underwear! His erect cock sprang into full view, impressively large and right before her eyes. Kana-chan had only meant to tease him about the bulge in his pants, but seeing a man's fully erect penis for the first time left her stunned. In retaliation, he flipped up her skirt and pulled her panties down. It seemed he'd been turned on by her panties peeking out from her short skirt all along. Overcome by a dirty, lustful mood, the two quickly moved on to sex. That first experience may be precisely why today's Kana-chan is so passionate about lingerie. Her alluring lingerie looks, the obscene naked body beneath, and her increasingly lustful expressions during play—this is something you absolutely must enjoy.
