Knock Out learns quickly with that level of attentiveness, and whenever he finds a spot that she seems particularly receptive to, he is content to lavish it with more diligence.

It's different than the night on the road... there, he'd been intent to bring her relief as promptly as he could. She'd been desperate then, but there had been discomfort in that need. How she'd been embarrassed at first, even though she'd acclimated more quickly to the situation than he'd have expected.

The touch of her hands on his neck cabling prompts a startled sound that quickly morphs into an approving reverb that traveled down her shoulder blades. He had neither anticipated, nor expected reciprocation in this but he's certainly not objecting. "Firmer," he murmurs, and offers her skin a feather-light nip in encouragement. Within his chassis, his engine purrs a deeper octave in appreciation. "Feels good."

When he feels that her upper body has been given enough heed for the moment, he trails fingers tips down to the waistband of her pants. "I'm starting to think you have a thing for staying half dressed..." he grins.
