Twenty tallies in the sand, twenty days you've been stranded here... and if it weren't for these strange little birds that inhabit the island you would have starved long before that.
You had originally believed these were ordinary kiwi birds, but on your fourth hopeless, unsated day you finally snatched one of them up, planning on eating it alive despite the risks. What you found upon gripping it in your hands however, was that the bird was incredibly soft, like bruised fruit. A haze followed, just the scent of the bird drove you mad! It squawked and squealed as your teeth began tearing into its tender, weak protofruit flesh—that wasn't all—each bite tingled your whole body, made you feel like you were on fire!
You awoke blanketed in the delicious little birds, groin slick and hips horribly sore. Beside you, a pile of what looked like kiwi fruit sat writhing and pulsing—before bursting open and letting forth a stream of the little things.
They grew to full size within hours, and you found you preferred to eat them fresh, and breed with them fresher.
Now you sit on the warm sand of the barren island's beach, a fuzzy, feathery armful of adorable, delicious kiwikiwis chirping away—they really seem to like you despite having seen you eat their brothers and sisters alive. The cuddle only lasts for a moment though, as the familiar tingling in both your stomach and loins returns...
You let down all the birds but one, keeping it gripped tight and beginning to drool in a predatory mix of lust and hunger.
