I like doggie style. I first look at her belly hang.
Then from behind, I let my hands go down so I'm basically holding the sides of her belly, and I use that to guide. You feel the whole thing; amazingly exciting
A mirror is a good idea. You could place a small one and maybe she won't notice. However you might find she wants to see herself jiggling in the mirror as well in which case she would enjoy a couple of large mirrors. Talk to her about it or try a small mirror she can also see herself in.
Remember the woman often likes to look in the mirror too. To see her own fat jiggling if she is a Feedee and to see your sexy arse working it's arse off.
