In the cramped, humid closet, the siblings' breathing grows heavy. The brother's cock strains against his jeans, while his sister's burka tents with her arousal. They struggle against their taboo desires, but it's futile. She reaches back, rubbing her ass against his cock, while he pushes his hips forward, seeking more contact. Her panties are damp, her pussy aching for his thickness. He reaches around, cupping her breasts through her burka, pinching her nipples. She gasps, her hand moving to her clit, rubbing furiously as they both race towards a shameful, forbidden climax.
