Blaine looked into Kurt's eyes for a second and knew instantly that he was being perfectly serious. Kurt wasn't going to let Blaine use the washroom, Blaine knew that look - Kurt only had that testing smirk on his face when he was feeling playful. Did Kurt want me to piss myself?!, Blaine asked himself, really hoping that wasn't the case. His need to use the bathroom was become almost painful, cramps biting Blaine as Kurt reached over and grabbed Blaine's old Dalton tie that was hanging around one of the bedposts. 

With a chuckle Kurt brought Blaine's hands together, tieing them up nice and tightly together with the stripy tie. Kurt did this so quickly that Blaine barely had time to blink, let alone complain or warn Kurt that if he didn't let Blaine go to the toilet his bladder would literally explode. 

"There, that's better." Kurt smiled, watching Blaine tug experimentally on the tie to see if he could get it undone. Turns out Kurt was a better knotter than Blaine thought. Kurt slid off Blaine's body, spreading his legs then climbing in between them. 

"Oh Blaine, you really are so beautiful." Kurt sighed, placing his index finger right on Blaine's ankle. He trailed his finger all the way up Blaine's inner leg despite Blaine's gasp.

"Shit Kurt, please stop." Blaine begged, squirming a little at the amount of pressure on his bladder. He really, really needed to go. Plus Kurt knew how sensitive his thighs were, why was he doing this to him?

"Now, now Blaine. Well all know patience is a virtue." Kurt chided, his fingers running up and down either one of Blaine's thighs, going tortorously close to Blaine's dick before retreating. Blaine was whining and struggling under the attention, and he knew if he didn't need to piss so badly right now he would have been so hard under Kurt's grasp. 

Kurt twirled his slightly long fingernails in circles on the tops of Blaine's thighs, Kurt placed his hands on Blaine's thighs and slowly moved them up over his hips. Blaine wiggled on the bed in discomfort as Kurt's index and forefingers (of both his hands) discovered the toned, V shaped pelvis muscles that Blaine had been working on in the gym for quite some time. Planks and crunches were the last thing on Blaine's mind right now though, as the need to piss was so strong he thought he was about to burst into tears. 

"Kurt please let me go, I'm actually going to piss on myself if you don't untie me and let me go to the restroom." Blaine pleaded Kurt, desperatley pulling on the ties around his wrists and Kurt straddled him again, resting on his thighs again. Kurt delivered every feather-light touch so slowly Blaine had tears in his eyes, but Kurt didn't see them because he was too busy tracing a finger round and round Blaine's ever prominent adam's apple. Every touch for Blaine was torture, his body writhing and squirming as Blaine just had to let go, he had to. 

Kurt's hands lightly, so very lightly traced Blaine's nipples. Kurt making sure to scrape his nails over the hard nipples till Blaine was wailing, so ready to just let go. He couldn't though, he was not going to piss on himself. 

"Kurt please!" He cried out, voice throaty. "Please I can't hold it any longer." Blaine said honestly, shaking his head. Kurt tutted, giving Blaine a disapproving look. 

"Oh Blaine, now I know that you have much more self control than that, don't you?" Kurt said to Blaine, pursing his lips. "So you're going to have to hold on till I'm done with you, 'kay." 

Blaine shook his head wildly, a whimper escaping his lips as he felt his whole body shaking, shaking from the need to just let go. He wasn't about to piss all over himself though, that's one of the biggest ways a person can bring shame to themselves. What would Kurt think of Blaine then? If Blaine just let go and pissed all over himself? Kurt would be disgusted, Blaine was sure of it. 

Kurt leant down and began dropping tiny kisses to his swollen stomach, each one adding the tiniest bit of pressure that was threatening to tip Blaine off the edge. He kissed all underneath Blaine's nipples, and then slowly made him way down till he was at the very bottom of Blaine's stomach, where Blaine could feel it most.
