The Master leaned against the headboard, one hand absently stroking Jack's hair as he watched the Doctor work, smiling as he felt him open up. Soaked up the want that the Doctor sent along, echoing it back mixed with a possessive sort of affection.
Jack turned his head slightly to press a kiss to the Doctor's hair, watching him as he continued, letting himself relax, and just be. Warmth and love and solid presence.
"Touch him, Doctor." The Master's voice was quiet, his eyes fixed on the Doctor steadily, almost unblinking. "Fingers and hands and lips and tongue, every inch of him." He reached out to lightly touch the side of the Doctor's face again. "Show me, let me see, let me feel it through you." He wanted to get lost in this, watching them both, his eyes fluttering closed. Get lost, and find his center, his balance again. The silence past it all.
