When Byleth's breath catches, Dimitri's gaze is back on him. He wants to see the faces he makes and hear every beautiful sound that passes his lips. Even as the bottle is handed to him, he isn't taking his good eye off Byleth for a moment. How could he? As he watches, clearly more than pleased with his view, he's coating his own fingers with lubricant.

Once he's satisfied, he's bringing his hand around Byleth's waist and down to circle around Byleth's burgeoning (if not already full-on) erection. He's careful, slow, and almost methodical with his strokes. He doesn't want Byleth to reach that edge too quickly now. Not before Dedue has his fun, at least. "I do," he murmurs, angling his head to dip in and press his lips against Byleth's neck, his cheek, and anywhere he can reach. "A royal view, really." Turns out, Dimitri can be quite cheeky himself!
