Star sees that intense look while the Predacon still pants hot air over his valve and flusters hard at the attention because *thats* a lot for him too now, but he doesn’t pull his hand out of PK’s hold

It doesn’t work bc strength differences, but Pk does stop with one last lick that gets Star to shudder, and then Pk grabs Star’s servo and goes to kiss his knuckles and palm while still giving him hooded bedroom eyes.
