It's poor wording, he'd meant arms... arms around his neck. Thankfully she didn't choke him because that probably would have not gone well.

Fuck... she's tight, and his head spins as he thrusts inside of her. His mouth falls open in quiet pants, carefully measured even in the throws of ecstacy. He's still doing his best to be cautious with her, pressing kisses to her lips each time he thinks he might have thrust a little too hard. It's a little harder to judge with her shifting her hips, but he's definitely not about to complain. He's seeing stars each time that he bottoms out, but he's digging his fingers into the wall, trying to make himself last just a little longer, just so he can keep enjoying her.
