Weaker Bottoms getting their Bussy beat up will tend to move away to blunt the power of the downstroke. When a hard dick is flying downhill into the asspussy, the weak Bottom knows that he's ill equipped to take the blow so he will move his pussy forward to take away some of the force of the hard dick mashing up his pussy. Good Tops, men like you, control the pussy motion. Like a boxer grabbing behind the head to pull the head into the punch. If a Bottom has done his work to train his pussy to take the beating (and love it!) we wouldn't have these problems.
I love this Top. I love how he holds on to his Bottom man. He puts his hands around the Bottom man and restrains him. Hold that pussy down! I love how he takes all the backstroke he can. He fucks with sincerity. He can fuck me any day.
