NE says I have a thing for walls because I have a habit of pushing her up against them.
It’s not just walls; I use doors, windows, whatever is available.
Why?
I like to trap her. It makes it easier to pin her hands over her head. I can press my knee between her thighs and part them. And it’s not just for me – when I slide to my knees and drape one of her legs over my shoulder, it gives her something to brace against while I nuzzle her stomache and bury my face between her thighs.
