alias vibrator_on_stomach -> womb_massage

BUR #40942 is pending approval.

create alias vibrator_on_stomach -> womb_massage
create alias vibrator_on_womb -> womb_massage

Hard to find tag.

I'd prefer to see this populated rather than be a utility alias. Not all vibrator_on_stomach posts are womb massages; I know I've seen at least one have_to_pee fetish image before featuring it.

Ditto

Feel free to populate it then. There's only 3 posts on it now.
