He wasn't really mad,  he just knew Kurt needed to learn his lesson for this. 

It all started when he was walking out the door for school and he swiftly  pushed the small pump dispencer of lotion to put on his dry hands due to the cold weather. He rubbed his hands together and started to wipe the remaining lotion onto his light yellor pants. An orange streak went across his pant-leg. 

"What the hell?" He mumbled to himself and started his car. 

It wasn't until a week later when the same exact thing happened that he'd realized there was something..odd, about this. Kurt constantly staring at his face like he was examining him seemed different to him too.

It wasn't until an over heard conversation between Kurt and Rachel, he realized what was going on. 

"I don't get it, why isn't he getting tanner?" 

"I don't know, the plan was completely full-proof, it should have worked.."Rachel said with a hint of disapointment in her voice. 

"Are you sure it was bronzer and not like, I don't know, something else?" 

"I'm positive!" She sqealed, before being shushed by Kurt, who looked over across the room and waved at Blaine, smiling at him, making Blaine temporarily forget what the two of them had even been whispering about in the first place. He hated that, he wanted to be angry, but it wasn't going to happen. 

Blaine spent the rest of the day planning how he was going to 'get Kurt back'. And somewhere in between lunch and sixth period he came up with the plan. 

Blaine invited Kurt over to his house telling him it was to 'do homework', but both of them knew it wasn't going to happen. As Kurt was knocking on the front door Blaine covered his hands in the lotion that Kurt had admited to putting moisturizer in to Rachel. He opened the door and before Kurt could even say hello he was pressing their lips together in a kiss. It lasted what felt like forever, and when they pulled away Kurt was looking for a breath. 

"Hello to you too.." 

Blaine responded by crashing his lips into Kurts again and leading him into the house. As soon as the door was closed, he was carefully unbuttoning Kurt's tight shirt. When it was off Kurt was frantically pulling Blaine's sweater off. After Kurt's shirt was thrown across the room Blaine just touched Kurt. He put his hands on his chest, his back, his abdomen. Just making sure he'd made an imprint on him. 

Kurt looked down to see Blaine placing his hand on his chest for what seemed like the millionth time. He wondered why he wasn't doing much else. He looked down to see his body covered in orange hand prints. "What the hell?" 

"Guess we both look good with a little bit of color.." Blaine smirked and held up his hands to show Kurt that they were a bright shade of orange. "Who told you this would work?!" He tried his best not to start giggling. 

Kurt's face turned an intense shade of red. 

Blaine leaned in and kissed his cheek. "Don't try that again.." He couldn't stop from laughing any longer.
