Nothing materially different between 30 and 60 really. They can come twice if they manage it, some literally come in the first 5 minutes.
Generally I won’t take outfit requests, role play requests etc. For 30 Min bookings. If they want something like anal in a 30 minute booking then in theory it’s possible but if they’re a piss taker wanting loads of services but only paying the minimum they can get away with I probably just wouldn’t do the booking. I pretty much treat 30 mins almost like quickies, and have some great 30 Min regulars. I don’t like the ones who want a 60 Min style booking but only book 30 mins, i.e lots of foreplay, oral both ways, toys, kissing and then after 25 mins of that they get mad because they haven’t got time for sex.
