Looking for a story about a mother and daughter who get transformed while stranded on a island

[LordOfWar69]

I remember a story from years ago that i have been unable to find recently. The story is about a mother and a daughter who get shipwrecked on a island. After they share a kiss, they transform in the night, with the daughter getting a massive cock, and the mother breasts growing. Any help or similar stories would be greatly appreciated.
