She was most definitely not helping his current state! The whole idea was to somehow make his current state actively worse until it reached its logical conclusion.

Which, by the sound of it, wasn't far off.

She managed a quick glance up at him on the pull back (and seeing the look on his face just resulted in another moan) but then her focus was back on the main thing. She'd done it slowly once, now. She figured she could pick up the pace. Bobbing her head forward to take him deep, then sucking on him as her lips pulled back, gliding along his length.

And then doing it over again.

It didn't seem like she had any real intention to stop and not let him spend in her mouth. Nope.
