She does as she's told: well, it's not like she can do much else without causing a massive scene and probably wrecking their relationship forever.

It's hard to deep-throat, even if she's not doing it properly, and she chokes more than once, and goes to pull back. But every time, she sees Cesare's face and feels just that little bit guilty for not giving him what he wants. So she lets him push her more and more until she really can't go any further. By now, her eyes are watering just a little, and her fingers are clutching Cesare's leg just a bit harder than necessary. Her hand moves on what is left of his cock, trying desperately to get him off now. It's making him happy, though. She can see it from his expression. He's happy and he's at least a bit pleased with her. It gives her a warm glow, and a tingly feeling in her stomach that makes her push all the more to take him just that bit further.
