Looking for a comic I read once or twice on exhentai or e-hentai. A french(?) comic about a woman who invites her sexist boss over to her place with the pretense of dinner and sex, only to drug him with some mind-controlling gender bending drug making him her slave.

The details I can remember are that in her backstory the witch doctor who sold it to her did a shit job so she ends up with a dick she can't get rid of, he's forced to live life as her maid and she's investigated in his missing person's case. It was a decently long comic, maybe 50+ pages? Something like that. There was this great page where right as she puts it in him, he just goes "OH!" and then it cuts to the outside of the apartment

any help would be fantastic, haven't been able to find it since
