This might come as a shock for some of you but a lot of us consider wanting to f**** the whole session very rude. We all know why you come to see us but offering a break, water or just asking if we’re ok is appreciated.
Same goes for purposely delaying your orgasm. If you’ve been at it for 30 mins with no intention to cum it’s not exactly fun. Take a break, have some water, let yourself be teased a little and then go back at it.
PS: intention and capacity aren’t the same.
P.S 2: I guess this would mostly apply to sessions that are 60 mins and longer
