Knowing that he’s lost in me…I groan loudly, panting. Listening to his harsh breathing, labored and fierce at my ear. But my body takes over, obliterating the thought, climbing and building so I am awash with sensation, meeting him thrust for thrust. Over and over, frantic, primal, desperate, and before I lose myself in the insane rhythm and pace he’s setting, I briefly wonder once more what’s driving him, worrying him. I wrap my legs and arms around him, cradling and holding him hard against me, determined to wipe out whatever’s worrying him, and he starts to move…move like he’s trying to climb inside me. He runs his teeth along my jaw, nipping and sucking, and then he’s kissing me again, hard. “I need you,” he growls, his voice low and husky. He stills, then swivels his hips once, pushing deeper, making me groan. He holds my head and with no preamble whatsoever he thrusts himself inside me, making me cry out-more in surprise than anything else-but I can still hear the hiss of his breath forced through his clenched teeth.

The description "he hisses" is inexplicably used. Christian is feeling super emotional after accidentally hurting Ana with some handcuffs, so they have sex to work through the feels.
