Netorare? It's mind control and I think the injured guy getting two horny nurses is a fair exchange.

A Mindwarping Syrup Turns the Entire Hospital Into a Sex Frenzy

Doctor Okuma spends all day in the company of nurses who,
in spite of being younger and less educated, make him feel like a fool.
No more of that! Using "saimin syrup", a cocktail of mind-altering glucose
he got from the pharmacologist, Dr. Okuma takes the upper hand...
and eats out the tasty snatches of his young residents-in-training,
a harem of brainwashed trainees, newlyweds and cum hungry sex slaves
who masturbate on command, go into wet slick heatwaves...
mindlessly given over to servile existence for the vengeful doctor.
He doesn't stop at the nurses, either! Even the patients are his...

So it's NTR in the sense that girls are married? If you don't actually see the guy though, and he doesn't know, isn't it just cheating? I thought NTR was that the guy knew and liked it, or he knew and was devastated.
