Perhaps it's not obvious in the club but Phil denies himself just as much as he denies his subs. It is a test of his control as well. He could very easily just take Loki's mouth and get off, express control by physical domination and selfishness but that's not his style.

"I think you'll do nice." Phil circles back in front of him, slowly letting his hair fall through his fingers. It's incredibly smooth and soft. Strong though. Phil imagines he could pull quite hard and it wouldn't break. And he saw how much Loki liked the sting. Easy enough to indulge that in the right circumstances.

"Keep your hands where they are." He holds Loki by the chin again and draws him in to rub his half-hard cock still trapped in his pants against Loki's mouth and cheek. "You can move them when you've earned it."
