just for the record your boob can't jiggle up and down from turning to the left. Also, boob jiggling is uncomfortable and sometimes even painful so all your favorite porn actresses are facing severe discomfort while you fap to them.
this has been a PSA
That wasnt a up an down motion on the boobs on Pyra, the impact is to the bottom left, the motion you see is her recovering from the impact. I would assume that the outfit reduces the jiggle here but I dont know for sure. As for porn, I dont actually fap to them when they jiggle, I only watched a few seconds of it because I am curious. But thanks for the info, I didnt know that.
