I like loud blow jobs.

I have to keep after my wife to give me loud blow jobs. Something about having her make those loud wet slurping noises gives me a super turn on. She doesn't like it if I blow a load in her mouth but sometimes I just can't help it. I usually give her a warning and she'll finish me off with a hand job. I make sure to do her nice and good after, so it's not like I just roll over and go to sleep. She thinks the neighbors might hear her if she gets too loud. Like I give a fuck. Anyway, is wanting a loud slurping blow job normal?
