Dio lifted his head briefly and all Louis caught was a devious smile on the Alpha's face before he placed an open-mouthed kiss on the same spot that had elicited that sound from him, his hands sliding up his sides to thumb at his stiff sensitive nipples.
That was more than enough to prompt more moans out of Louis, the Alpha squirming slightly from the pleasure.
He felt Dio drop his head against his shoulder and as the haze of euphoria faded a bit, he could feel him whisper curses against his heated skin. Louis clenched his fists a couple more times, he wanted to touch Dio, he wanted to run his fingers over every inch of his skin. He also wanted to cover his face so he wasn't going to ask to be untied, even if it killed him, he wanted to be fully present for this.
"Lou, I love the sounds you make." Dio lifted his head to say, his eyes were slits from how low his lids were over his eyes.
