If my wife is really aroused, like already had an orgasm, then bottoming out is very pleasurable for both of us. It feels sort of tight around the head of my penis and some gentle motion, sort of rocking back and forth, drives her wild. Thrusting is too much and I don't think feels good for her. After this kind of gentle bottoming-out stimulation she often passes out very happy and sleeps like a baby. :)
