Just felt the need to reply to this one.
Obviously, in all cases the woman would be a willing participant. I'm an enlightened sadist, not a sociopath. If you mean the baby that might result, I certainly have no intention of forcing pregnancy-related degradation on someone who isn't already pregnant or willing to become so (and subsequently treat that pregnancy like any other). I'm sure nothing bad would befall the baby as a result. This sort of play is 90% mental.
Such things all seem non-consensual because in "normal" society no right-thinking woman would ever consent to such things. In the dark corners of the mind though, and safely cloistered away in under the supervision of a certain person, some women are perfectly willing to consent to, and be mercilessly complicit in, their own degradation.
That's what I'm looking for.

EDIT: This thought almost made me laugh out loud- I'm not sure what scientists are currently saying about the effects of external noises on babies when they are in-utero, but if tone of voice (speaking harshly instead of soothingly, for example) is something that affects an unborn child, then verbally abusing a pregnant woman might be actually be a discouraged pre-natal practice for doms and their wives. Hell, for all I know, it is! Has anyone written "BDSM For Pregnant People" yet?
