As you'd expect from a lingerie shop, Kana immediately showed off her sheer underwear for the shoot! Of course, Kana's naked body was just as erotic as her underwear. However, she seems a little insecure about her breasts, so I started massaging her breasts under the guise of a breast augmentation massage. Seeing her shyness while being massaged made me want to tease her even more, so I started massaging her nipples with a vibrator! Then, as Kana's pleasure gradually increased, I hit the vibrator directly on her crotch. It felt so good, she squirmed and twitched, and then I said, "I came..." Kana's first sexual experience was with her younger brother's friend. Her younger brother often brought him over to our house, and they'd known each other since they were little, so they often played together. That day, as usual, they started out messing around, but when he got on top of her, I noticed his crotch was erect. When Kana-chan finally said, "It's standing up," he replied, "It's not standing up," so Kana got angry and pulled down her tracksuit, revealing that he had no underwear on! His cock was in full view, its full, erect size right in front of her. Kana-chan had been planning to tease the man's bulging groin through his pants, but she was stunned by the sight of his ripped crotch for the first time when, in return, he lifted her skirt and pulled down her pants. Apparently, he had been reacting to Kana-chan's panties, visible through her short skirt, and the two, engulfed in a lustful mood, went straight for sex. However, it seems she hated the fact that her first experience was just plain white panties, and that experience apparently led to Kana-chan's current obsession with underwear. Enjoy Kana-chan's sexy lingerie, her naughty naked body wrapped in them, and of course, her facial expressions as she becomes more and more erotic throughout the play.
