Rob jammed the lid on the box closed and retreated to his room. He unbuckled the belt on his jeans and opened his fly so he could see if this would work, still unsure if this was even possible. Kneeling on the bed he laid out the box in front of him and reading the instructions carefully he picked the first chocolate he would need for his idea.
