Yes, of course. Sometimes when you are in a long term relationship, you have to give up a Mercy Fuck or a Pity Blow Job once in a while. I know
My Man does it as well. It's give and take.
In the event that I really
didn't want to, or was ill, of course I'm going to say no, and give him a rain check. But, often, like Airen, I get in the mood if it's just a "Nah, I don't feel like it." time. (Not that I have those all that often.)
