Oh his focus was entirely on Colin, all his energy on him, on watching and seeing and learning and oh bloody hell, Zach wanted to hear the noises he made. And his eyes stayed on Colin's face, and oh, that was so beautiful. Colin's whole body moved into him, yes good, and Zach felt the hips pushing into his, but what mattered more was Colin. Oh Zach loved to focus on him, on the way his hair fell to frame his face, and the way he trapped his lower lip and already begged for more. Yes, more.
His hand pumped up and down a couple times, but while it went just fine, nothing wrong with it, lubrication was better. There was the supplies like what he had shown Colin, but more effective at the moment...his other hand grabbed his wand again and cast a small charm, just to provide a little bit, yes. And Zach moaned against Colin's lips as his hand moved smoother. His thumb continued to flick across the tip as much as it could, and Zach hungrily kissed him.
