Eyes closed, bottom lip bitten and eyebrows kinda frowning but not frowning.......I'd imagine. That's what it feels like anyway!

Then again sometimes, my eyes are just screwed up really tight and my teeth are gritted. It depends what's being done and how close to the end it is.

I can show you my 'After fuck face though':
