Fletcher smirked slightly, a hand sliding into Zach's hair and tugging to maneuver him where he wanted as he deepened the kiss. It was quite obvious what he felt on the matter, and he was finding out quite how obvious Zach's feelings were as well. Well, then. He'd made sure to use a sticking charm to keep the desk from moving. Might as well test them out.
Turning Zach around, Fletcher pushed him back against the desk, aiming it so Zach's hips would press up against it. He hummed against Zach's lips, pleased for the moment. He wasn't sure quite how flexible Zach was, but it could certainly be discovered, couldn't it? He leaned forward a little so as to press Zach backwards, slipping his leg between Zach's. "You really want it bad, don't you?" He chuckled softly.
"And I'd hope you would, too." He hummed thoughtfully, nipping at Zach's lower lip. "Now. Do you want to be on your back or feel it in your hips for a while. I plan to leave a bruise."
