Does anyone remember what this story is?

[Guest Yaminisu]

I'm looking for a Yami x Yugi story where Solomon and Atem decide that they want to arrange a marriage between their first born children. However, neither man gives any thought to the possibility that they are both guys. Solomon then turns Yugi into a girl and names her Hikari. Her and Yami marry and after Yugi gives birth to Yami's and her children she turns back into a boy. I never saw how that story ended and I can't remember what its called.
