Bound by blood and confined by their parents' absence, these siblings can't resist the pull of their forbidden attraction. As they sit together, the brother's cock tents his pants, obvious and enticing. His sister, with a wicked glint in her eye, reaches out and strokes him through the fabric, making him groan. They're playing with fire, they know, but they can't stop. She unzips him, taking his cock out and licking it like a lollipop, while he watches, mesmerized. He's hard as a rock, and she can't wait to feel him inside her.
