Zach's face through the whole thing was priceless, and Fred only wished he had a camera. At least he wasn't too horribly surprised; Fred saw Zach open his mouth before he'd done anything - he'd probably suspected something already.
Following Zach's unbuttoning with his eyes, slightly surprised when he stopped at only a few, Fred waited for Zach to relax before completely jumping on him. And the way Zach lay there, the way he seemed so calm as he looked so sexy, only made him hungrier to start.
It only took a moment for Fred to decide where he wanted to start, and he dropped to his knees, undoing another button and pushing Zach's shirt to the sides so he could get the chocolate dripping down his chest. Beginning at the end of a particularly long trail, Fred simply licked his way from the center of Zach's chest all the way up to his chin, softly kissing it before moving back down again to catch another trail.
