I really enjoy a good chat if the girl is friendly and interesting. At my age I only go for 30 minute punts because I'm at least 24 and more like 48 hours between pops, so no point booking an hour unless its to have a long, slow massage first.
I know one local WG who just loves to chat though, first time I went to her I stayed 40 minutes, no extra cost, and the next time it was a full hour, after the sex we just sat naked and chatting before I went. I actually offered her more money but she said no, she'd enjoyed the company, and genuinely looked sorry to see me go. WGs like that are extremely rare though.
