3Some

Sounds like his anger is due to feeling inadequate because the lady had 5 orgasms that night.
(Reading into it, the fact that she mentioned five, suggests it was more than she was used to)

My tip for future women encountering 3sums that are arranged by the man.....
Make it look less good than it is, when the 'other guy' fucks you so your man always will feel good.
Then; and I suggest this genuinely, meet the other guy on his own and experience him fully.
I shouldn't think of it as cheating but, more, research, so you can do something new for your own man afterwards or learn a new way to have your own (best) orgasm. 

I suggest you don't do ffm unless your mmf are perfectly OK without consequences. Better to meet a girl alone and explore without a guy interrupting you.

I could not agree more before joining with a new couple , regardless of if I had coordinated with the wife or husband first, I always, always speak to them both and get assurances that everyone is on board and if either of them has any redlines about what can and can't be done. Still it isn't foolproof I had a similar bad experience with a hubby who said that he was onboard and wanted to be cucked...right until I dropped my pants and he saw what I was working with and his wife wouldn't stop moaning and cumming as I got in there and took care of her business.  All of a sudden I heard a noise from the corner chair that he was sitting in.  He was boiling over angry, I guess that she didn't react that way when they had sex. Once she realized that I was pulling out because of him she tried to keep me in there pitching and then she got really angry at him  because he interrupted her happy time.  They were still arguing as I threw my clothes on and headed out the door to my car.  She ran downstairs and yelled out the front door behind me that she'd give me a call about another time    I just waived bye bye.

Real life multi-party sex is not like its depicted in the movies, to get it right it take a fair bit of coordination and thought to get everybody in sync and on the road to happy town.

Mmmm I'll be orally pleasing every one there and offering my anus if the men need to use it x

Its a common thing they are all up for it and when it comes to it getting hard it just hangs there looking sad.

Had to think outside the square. A soft cock can be sucked. Women don't have the patience to get you up. A good cock sucker and you're up and off. Still, in a 3some once, I held a man's balls in my hand while he was fucking his wife doggie style, fingered h we clit then felt his balls tighten as he shot a load into her.
