I like how she seems so into (or is resigned to) passively letting him fuck her face. I can imagine them having a relationship where she's a submissive who works from home, and within minutes of him coming home from his job, this is how she greets him, on her knees. No hands up means she's got no brake on his thrusting. There's not a lot of movement, but the drooling tells you it's deep, at the back of her throat. I would've liked to see this one "come" to fruition.
