MC is fucking both of Antonio's sisters, but your danger line is at fucking his wife, who Antonio doesn't want to fuck.
Agree he'd have to kill any man sleeping with his wife, as a matter of principle, but I do think he'd be more angry about finding out his little sisters were getting boned, than his wife.
To be fair, at this point, if anyone finds out about anything, we're a dead man walking! So yeah, I do take your point.
Still. Worth it. lol Worth it for that dinner with Luna, alone! Go to the grave with a smile following that.
