I recently had a guy, that when he shot his load,made one heck of a noise whilst he cum.
It isn't a problem for me, in my location for work.
The louder the better, as far as I am concerned.
You know that way he will probably come back and nothing worse, in my book, for a guy that cum's, that hardly makes any noise, or show any emotion whilst ejaculating, sometimes I have even checked to see if they have cum, if they've not unloaded much.
What's everybody else's opinion on this.

Not ideal in a hotel with cleaners right outside your room.

I can recall 3 howlers/shriekers when they orgasmed. I hate it but if during the day I know the only neighbours who could possibly hear are out at work. The 3 who used to visit me found they could not get an answer from me after that so gave up.  Any new howlers I may yet meet will be one offs.

No good asking them if they book again to not howl, it would probably spoil their fun and dampen the booking.

I work in hotels and had a client a few days ago, I kid you not. Literally growl like a demon right in my face whilst on top of me. I have never held in a laugh so much in my life. However it was awkward as the cleaners were only two rooms away from mine and I'm sure the whole corridor heard that. I do try and politely say sometimes if I think they will be loud that please keep in mind that we are in a hotel and to be mindful of our discretion.
As in hotels it can be VERY awkward.
