Title is a little misleading, a little proverbial if you like: - I don't mean workplace bosses, i mean girls who don't seem to be able to climax or really reach orgasmic levels, no matter how grand you fuck them SGM or otherwise.

My example, a girl I am fucking seems to be able to resist my pipe laying: I am fucking her with everything I've got, holding her down, legs spread on her back or doggy - pounding away with a hard erection - going deep - she moans and her eyes are big, sweating but ulitmately she doesn't CUM/"GO" like in porn or the like. I don't get the vibe she took all she could take like people who advocate SGM or 'rough sex'.

IE: she seems like a boss at the end of a video game level you cant "BEAT".
