Strong silent top, whimpering bottom

I have come more times to this photo than any of my others.  This sums up perfectly what I like about sex:  the top looks strong, silent and is just using his bottom's ass without regard for how much his bottom is crying and yelling.  From the look on this bottom's face, he seems to be saying "stop! stop!" but the top just keeps pumping steadily.  And of course the bottom is going to explode in an unbelievable ass-orgasm.

Get me some lube and a towel, right now!
