Kurt opens their mouth for him without complaint, only teasing their teeth at his knuckles with a shaky moan, letting him reach all the way into their throat if he wanted to. It's a big sign of trust from someone who used to be so careful, so vigilant. They know none of the wolves will hurt them, so they let them do whatever they want to their body, trusting they will be safe.

And they always are. They've been bitten, spanked, choked, had hands around their throat or fisted in their hair or pinning them down, and aside from that very first night, they've never been scared. In fact, it's exhilarating, the loss of control, of movement, of air. It makes sex even more playful and challenging and delicious, having that touch of pain, of danger.

Because they're always, always safe.

"P-Please," they gasp, not caring about the drool wetting their chin, the reflexive tears from Kai's fingers teasing their throat. All they care about is the slick weight of his cock against their hip, the smell of him making them lightheaded with need. He rocks his hips, and they rock back, increasingly impatient, legs spreading even wider, inviting him in. "Please, baby, fuck me! Pleasepleasepleeease, n-need your thick cock inside me. I need you, Kai, b-baby, please, need you to fuck me so hard!"
