Sounds like a great experience. So glad you didn't say something negative or treat it as weird.
In a shared space like that that is all but vacant I dont see any issue with taking care of business.
Its cool that you said it was okay - cool that he asked if it was okay - and even more cool that you were fine letting him and then doing it yourself.
We've all been there - so horny - you just need to cum. Then its done. So would be great to know its acceptable - sadly, most think its not.
