The good thing about Jyn's lack of expectations is that there was no way that Cassian could disappoint, but boy howdy does Cassian hurdle over those expectations like an Olympic pole vaulter. The first touch makes her jerk in surprise but everything after that is just Jyn melting under his touch and dissolving under his mouth.

The warmth builds down in her belly until she has to grab a pillow and press it over her face so all her little noises and gasps and screams won't wake up the baby in the other room. Or the neighbors because god damn even the pillow can't muffle everything. Is the window open? Does Jyn give a fuck?

Once she's spent, legs still shaking, she drags the pillow off her face. "What the fuck, Cassian. I'd have come home six months ago if you'd told me you could do that."
