Afraid about what he'll say

John thought it will be the best birthday ever. He just found the recipe of a beauty elixir and decided to use it for his husband, Christopher. Chris was always the "handsome" one of the couple so, John thought it could be fun to offer his husband the body of an Appollon for a glorious birthday sex.

So, when he drank the potion, he hurried to a mirror, waiting to see how his face and body will transform. But John saw quickly something was wrong. Firstly, his body became slimmer, with soft curves. His hair became longer as two protuberances appeared on his chest.
John wanted to scream but his voices was now higher than ever. He checked between his legs but his proud cock vanished.
He was now beautiful... but also a woman !
Then, John made some research and discovered his beauty elixir was designed for women exclusively. Fortunately, the effect will disappear in one day.

But now, as Christopher comes back from work, John was stressed. How will he react when he'll see that his husband was now a woman ? What a birthday gift...
