Pillow Masturbation

I need tips on pillow humping!! I was trying it out tonight and was extremely wet to begin with but after about a minute or so of humping and being so turned on by the thought of how hot it was nothing was happening !! I just ended up a tired naked mess and gave in by rubbing my clit to reach orgasm. So please if anyone has any tips to be better at pillow riding/humping comment them !
