Knocked
When a young man contracts Fem Flu, the mysterious phenomenon that turns men into women, he immediately realizes this is the best thing to ever happen to him. However, that presents this now-woman with a different problem: there’s only one known way to make these changes permanent, and that’s to get pregnant. Is that something she’s ready for, and can she do that responsibly? And, if so, how or with whom? There’s only six months to figure it out, and the (biological) clock is ticking!
(Note: while I wouldn’t categorize this story as smut, as that’s not the emphasis of the story, there are obviously R-18/NSFW moments and discussions involved)
