The siblings' bodies shine under the harsh light, their skin slick with oil. The brother, his massive cock standing erect, watches as his sister, her eyes filled with lust, approaches. She runs her oiled hands up his thighs, her touch electric, making his cock twitch. She leans in, her breath hot on his ear, "I want to feel you inside me," she whispers, her voice laced with desire. He groans, his grip tightening on her hips, pulling her closer, ready to give in to their forbidden craving.
