8 XXX : ballsucking

Honest question. Guys and girls - just tell me this. How do you guys get your balls licked like that. My balls hurt so much when my girlfriend tries to do that. :)
I love my balls to get suckk and pulled. But hey who else notice her suck up that big white hair!!! Lmao. Good lil cleaning machine
It never hurts at all for me.

I love it! I even like light nibbling! I can deal with a little pain, but not much.
