Often when his hands are occupied with something else, or when he needs to be restrained just to give my mom chance to fully oil me, my brother’s dick can jerk itself, the foreskin pulling back and forth over the permanently cum-soaked head as if being worked by invisible hands with a loud sound of “schlop schlop schlop!”.
The auto-jerking is powerful enough to shake his whole body as he groans gutturally, the only thoughts his brain are able to even process any more being ones of a pure, hardcore pornographic nature.
