Guys, He wants to bury my face in pillows?

I've been talking to this guy for almost 8 months now and things recently have gotten sexual, and he said during one of our spicy interactions that he wanted to bury my face deep in the pillows and I'm not very familiar with that expression and when i google it it just pops up as someone being tired but I'm wondering what he means by this.
