IIN if I'm talking to my boyfriend and all I' want is anal fingering?

I can't say that people normally get that urge during every conversation but you know what, that is very kinky. Its almost a sin that he hasn't already felt your persuasive waves of lust in your presence already. I'm curious if you'd literally want to tell him one day, "You know, its really okay if you'd like to finger my butt while we're talking." Oh yes, its a dare. He might even agree. *cue shiny glasses trope*
