Zach's chest began to to heave up and down as Fred unbuttoned the shirt entirely. The mixed sensations on his chest were only getting better - warm chocolate, cool air, Fred's tongue. His body ached for the attention whenever Fred's mouth left to lick another spot of chocolate. And Zach tried to concentrate on keeping his eyes open, on watching Fred lick up from his abs all the way to his chin.
His shirt was fallen open, and Zach moaned, begged, without a thought to anything else.
