My Ichika sister Ichika has been acting strange lately. She comes to my room to read her favorite book, but she stares at me and doesn't take her eyes off me. I'm captivated by her sparkling Hitomi, and then I notice that her hips are moving! She moves up and down and left and right, and her breath escapes from her mouth... I was interested in Ichika's immature body, which has yet to experience sexual intercourse, so I licked her clitoris, which had become sensitive from masturbation, and inserted my rock-hard cock deep into her vagina. "Don't tell anyone," she said, but I ended up cumming inside her, due to the pleasure of her slippery pussy juice and her immature tight pussy, and from then on, Ichika's unconscious seduction became even more extreme...
