Sometimes it's worth going over the yaoi section because genderbender stuff gets pushed into that category.

@mikol It is Shiroe and it is not. First part is Roe2 herself (if you consider that gender bender or not is another matter) having sex with Crusty, but in the second part Shiroe and Roe2 swap bodies and then Shiroe has sex with Crusty in Roe2's body (if you consider that yaoi or not is another matter).
