With a quick glance down the hallway, the siblings slip into the closet, their hearts racing with anticipation. The girl, her pussy already wet with desire, reaches for her brother's bulge, feeling him harden at her touch. He groans quietly, his hands finding her hips, pulling her closer. She can feel his cock pressing against her, her panties soaking through as their bodies grind together. Their clothes cling to their sweaty skin as they lose themselves in their taboo dance, the sound of their heavy breathing filling the cramped space.
