She gasps as he pushes her against the wall, his hard cock pressing into her from behind. Their breaths quicken, hands fumbling with buttons and zippers, eager to feel each other's bare skin. The air is thick with their scent, a mix of sweat and lust as they grind together, lost in their taboo dance.
