I think I'm ready to do it.

Tony did not really want to do this but after 3 weeks trapped in his wife's body and just after experiencing her period he was extremely horny and could not resist her body's urges any longer.

Sarah who had wanted to try this from day one and had refused to switch back until they did it was over the moon when her husband came to her begging for her as he stripped off to bang his brains out.

Which turned out to be the best sex either of them had ever had in their lives which led to them extending their stay as each other indefinitely.
