Since high school, when his little sister's breasts first began to develop, the older brother has seen her as a woman. Now 26, he visits her home for an overnight stay after she moved out to live on her own. Just like back at their parents' house, her panties are still visible—and when they're alone together, nothing has changed. Excited by the sight, the brother pounces on her. The busty sister shows little resistance as he devours her big breasts, even returning his kisses. Soon her panties are pulled off, and penetration begins. They bathe together for the first time in ten years, and she eagerly sucks his now well-developed cock. Could she secretly have feelings for her big brother? He shamelessly gropes her tits and pussy, thoroughly enjoying every inch of her body.
