If you feel you cannot mate while I remain alone and unfucked, choose someone for me.” He leans forward, rubs his cheek against Baelor’s clothed shoulder. “I will gladly be put on my back if it brings you peace.” Gladly is a stretch of course. The things he does for his brother. For the realm. If his dam could see him, she’d be struck down in surprise and joy.
“No.” The words barely pass his lips, the way Baelor’s teeth are pressed together. One of his hands reaches for Maekar, digging into the fabric of his sleeve, then his thigh.
“I cannot bear to see you with another. Not again.”
