She does, at least a few times

Attempt #2, continued :

After a bit of warm-up, Eve had the bright idea of using her pussy to milk his cock. She justified it as being perhaps more effective - but really... she was starting to get frustrated and could use some satisfaction. She just wasn't ready to admit that to herself yet.

So she had tried to quietly slip him into her pussy. Eve had moved as slowly as she could, trying to milk his cock in the most pleasant way she knew. She managed to thrust a few times, but John woke almost immediately from all the movement - Eve had only had a few awkward fucks that had given her no satisfaction and no real experience. The fact that Eve hadn't been able to stop herself from emitting a gentle moan hadn't helped either. Getting even the slightest action in her thoroughly neglected and teased pussy felt so fucking good.

He had laughed, called her a thirsty, unprofessional cock-**** slut, then face-fucked her extra hard before telling her she would have to work a lot harder to feel him in her snatch the way she desperately wanted. Eve knew in her soul that every word he said was true.

At least she was able to sleep longer when John woke up, because then she was able to get him off as quickly as she could... but she hated, absolutely hated being put to sleep by suffocation. She would lie there, pushing her nose into his hips, as her eyes started to tear up and she started to sweat. Near the end she would start twitching, and no matter how much she tried to control it she just could not stop. It hurt. So fucking much. But after a short time her world went black.

Attempt #3:

Finally, success!

Eve hadn't really slept. Not really, at least. She was woken up with a shock three times over the next six hours. Being woken by asphyxiation was not pleasant, and it never got easier. She always got hit with a shot of adrenaline on waking, and took a few moments to realize where she was and what she was doing. Honestly, she thought it was ****, and it got worse as the night went on.

She figured out how to avoid moving enough to wake up John, but it took so damn long to get him to cum. He'd cum so much already, and it was starting to take a lot of work to get him to come again. But she had her orders. She'd laid there, awake for what felt like an hour, sucking on his cock, praying that he would cum so she could go back to sleep. Her throat and jaw felt sore, her back hurt, and she was exhausted. Worst of all, she was almost afraid of the dick she was gently licking because of how many times she had been choked **** by it. It loomed before her vision, but she conquered her fears and had returned to gently sliding it past her lips. Had it really been an hour? It had certainly felt like it.

Mercifully, she'd felt him start to pulse, and without even fully swallowing she'd sank her head back down to his hips, starting to go to sleep. John's cum dribbled out of the side of her exhausted lips. She'd barely remembered to slide his cock back in her mouth before she drifted off.
