Being a second rate slut has drained this girl of all her energy, so she catches some Zzzz's in the middle of her own porn shoot. Wise choice, this beast needs all the beauty sleep she can get.
These girls just do anal cause it'll land them an extra $200 on their paycheck. That's a lot like getting paid $1,000 to go down on a 400 pound lady & then being offered an extra $100 to toss her wart-infested salad. It's just not worth it.
