It sucks but thanks to my computer messing up and deleting my entire history, I don't remember everything that I saw such a theme being fulfilled and the only Japanese comic that I found that comes close that is here:

It seems like it's about a couple or a super hero team investigating something, but the woman gets captured by a lizard man and have sex with her to turn into a lizard girl. The guy eventually finds her and saves her from him, but it seems like her mind is in a feral state and luckily she still remembers her still human lover.
