Use the following tags:
fucking machine vaginal penetration medium speed
fucking machine anal penetration medium speed
I tried to make different speeds available but it doesn't really work. Maybe it needs more training, I hope I can do it in a second version.
If you're using a NSFW model the woman will almost always move her hips, this is really hard to get around since NSFW models are trained on a lot of sex scenes but you can reduce it by adding this into the negative prompt:
boncing, jumping, shaking, moving hips, bouncing hips, shaking ass, hip movement, body movement
It's a lot more prominent in certain positions so if you really want to avoid it try a position where women usually don't move.
