[machiavelliclassics]

Looking for Trans Vacation Story at a lake house or beach house. Guy goes on holdiay with single parent and the single parents new boyfriend/grilfriend who has a similarly aged "daughter". The son and trans-daughter share a room for the vacation and end up fooling around.

Something about a beach, lake-house or cabin. I thought I read it on here. Its all very vanilla and sweet.
