It’s when man transforms into a woman and has to have as much sex as possible before he changes back. I am aware of the mtf_transformation tag but it’s mostly just rule 63 stuff.

Hmm, I'd say you should look up some hentai with that phrase

It just sounds like some hentai plot lol

Highly specific, i doubt there is a tag for that

Yeah that's way too specific to name I think. Sounds pretty cool tho, keep us informed.

I suggest calling it Freaky_friday_(gone_wrong)_(gone_sexual)

Where would I look it up? I mainly stick here for general hentai. And thanks for the help guys! Ill keep you guys posted on the findings. ^-^
