Under the dim light of their Oaxacan room, siblings shed their jackets, revealing bodies taut with tension. The brother's cock tents his boxers, a wet spot forming from his leaking precum. His sister, cheeks flushed, watches hungrily as he strokes himself, her own hand rubbing her clit through her soaked panties. The air is thick with their lust, the scent of sex and the sound of their sticky, lubed-up bodies driving them further into their forbidden dance.
