Generate the first chapter of a twisted but sensual story, from first person pov, with this setting: 

The world collapsed long ago. Reaching the Federated Union of Free Cities requires one to cross The Great Wastes, a desert plain filled with slaver bandits, cannibals and worse— the Tittilianid, a huge spiderlike arthropod, the females of which prey upon hominid women; pulling them into the air and stripping them with their appendages, they feed off the bodily fluids of women through tickling them until they pee, before impregnating them with their eggs to lay. Nothing a traveller could fear more than encountering a Titillianid in need of a host— especially as a ticklish woman. 

Detail our protagonist's arduous journey across the wastes. At the end, she must encounter her worst fear— alone, and a Tittialianid has seen her in the distance.

Do not mention these things literally, work them into her personality. Detail her appearance, and her feet.
