SONE-507 Sneaky and perverted little sister who deliberately lets you peek at her while she's in the bath Himesa Hime

At first, it was just an accidental peek... but soft-looking breasts, a fluffy peach butt, and a tightly cinched waist... I felt a stirring at the sight of my sister's developed body during puberty and found myself getting an erection. I knew it was wrong to think this way, but I couldn't help but watch my sister taking a bath, becoming increasingly captivated by her. One day, our eyes met... "I've known you've been watching all along," she said with a devilish smile. Her words flipped my lust switch, and the sight of her wet hair, the faint scent of shampoo, and her summer-sweaty skin drove me wild! Despite the taboo feelings... I couldn't help but lick every inch of that perverted body I had been spying on, our bodies slick with sweat as we intertwined... Our bodies were too compatible, and my sister letting me see her in the bath became a signal for forbidden sex...
