Easy,I know where to go narrative wise:

>keep having sex
>cum inside her like semen demon
>gets pregnant and finds out spell become permanent when pregnant
>when it becomes permanent she forgets how to be,act and what it was like to be a man.
>turns into a girly wife with more kids on the way.

The end.

I see what you did there, no pregnant follow up though?

I mean jizz

I hope it ends with jazz all over her face and mouth.

Perfect, now you can do plenty of nudes like this and make it look even more attractive

Oh wow that's still a thing?

Yes! More of her! Love it when they get turned into girls all of a sudden, also love the clothes barely hanging and being dominated afterward.

If it's a girl it probably also has a sailor moon uniform.

More of this please! I'd love to see what the gender bent jock goes through as a pretty little cheerleader, maybe she doesn't have any panties on during the big game and has to cover while she cheers, maybe she gets her clothes stolen by the other girls and is force to do a walk of shame hopping no one catches her, the possibilities are endless.
