Kate's ambivalent about one thing and only one thing when it comes to blow jobs: whether they should be fast and hard, him fucking her mouth, or slow and leisurely. Since this is just for him (kinda, since she gets off on it anyway), she decides fast and hard today, and gets messy about it.

She's not even trying to draw it out, just giving him everything she knows he likes and then some. Her mouth is wet, spit's all over her face and his thighs all mixed up with his precum, her head bobs, cheeks hollowing to suck him in deep and throat open to swallow him. He'll probably have a set of bruises from how hard she's holding his thighs for balance, and she'll probably lick and suck and bite them to make them bigger.

She's his, but he's hers, too. And she always makes damn sure he knows it.
