Taboo kinks

I have a client who is currently sending me Daily Cash to make fully clothed videos bubbling my spit in my mouth pretending it’s his cum. Where it gets taboo is he wants me to use words like I’m swallowing the babies and sending them to heaven and say bye bye to the unborn babies. He’s also into piss play and wants me to gargle his.

He’s offering me cash to travel to meet him once a week and do this in person for him. I’m just worried about the fact he uses terms like killing the babies and heaven and stuff but it’s a lot of money for me weekly if it works out. Has anyone ever done anything like this ?
