One of the main comic he draws is Condom Crusader, a story with an erotic crime fighting duo of foxes who firmly believe in safe sex between consenting partners or groups. I went with something in a similar vein of the comic, featuring my vixen as The Technomancer. She also enjoys safe sex between consenting partners, and will deploy technologically advanced methods to ensure it's enforced. The tentacles curled around her leg and arm are loaded with a veritable swarm of nanites encased in a largely hydrophobic thermal dissipation gel, making them as warm as flesh to the touch.
The host of nanites can be compressed to a point of holding water for short periods of time, making for a quick deploy condom-like form when protection is necessary, and no standard protection is available.
