Dear Community

I once read some captioned sequences about a couple swapping gender. It usually included a submissive girl / young woman and a dominant man who volutairly (or at least partly) swapped genders. Unfortunately I lost track of this pieces and hereby hope to find them or similar sequences or even stories again, since I couldn't find any trace of it by search in the forum/internet by myself.

I'd appreciate any help on this.
