Spock rewards the truth with a harder squeeze. Tight enough to finally restrict Jim's breathing into something shallow and abbreviated. Spock knows just how much a human can take at this level before the deprivation becomes concerning. But Jim can still breathe, so they have a long while. Unless he tightens his hand even more.

"Good," he praises, his other hand coming up to stroke along Jim's cheek. "Did you self-gratify yourself, after that event?" His fingers press lightly into Jim's psi-points, testing his mind before pulling them away. Spock might be the most cautious Dom in the entire world, but it came from the utter inability he had to live in a world without Jim. Especially if he was harmed at his own hand.

"I am certain you did. How many times, Jim? What was your favorite fantasy? How did you desire for me to have you, the next time?"
