Finally Draco relaxed enough, but it wasn't long before he tensed again. Snape stopped pushing but kept the pressure steady, gaze cast up along his body as his head fell back against the bed, lips parted. The low sound that tore from his lips tugged at Snape, and he felt his cock twitch, pressed tight against Draco's thigh.

He's so tight, so vocal, and Snape can't help imagining how it will feel to finally be inside him. His voice is soft though the words sound almost like a reprimand as he murmurs against his chest, "I said to relax…"

Draco is so reactive, so sensitive to touch, and he can't resist doing it again, this time flicking his tongue over it and, releasing it from his teeth, swirling slowly. As much as he had wanted to punish him, hurt him as he wanted to be hurt, he wanted to make him feel just as much pleasure. When he feels him relaxing he presses in again.
