"Alright guys, take five."
The Gleeks sighed in relief as Mr Schue let them stop rehearsing their new dance moves. Glee was fun, but exhausting. They sat back in their chairs and chatted. Puck made some comment about being able to turn on anyone, anywhere. Kurt said to Mercedes, "Yeah right, because so many people are turned on by absolute jerks."
Someone started humming Akon's Smack That. Unsurprisingly, most people joined in, a few of them moving in time with the rhythm. As they reached the chorus Kurt, Mercedes, Puck and Santana stood up and began to properly dance to the music. Puck moved over to Kurt and began to grind with him. Kurt stopped moving and looked at the older boy, "You do not want to do that."
"Shut up, Hummel, just dance." He grabbed hold of the younger boys hips and moved them in sync with his own.
Kurt gasped as the other boy pressed against him. He'd never been to so close to another guy before. And it turned him on a little bit.
Puck was grinding into him, singing Smack That. Forget a little bit, it turned him on a lot. Kurt turned bright red as felt his erection growing. He tried to disentangle himself, but Puck kept his rock hard grip on the smaller boy's hips, and Kurt's twisting only moved the two closer together.
A few the others noticed, including Finn. His initial expression of amusement turned to worry as he felt himself begin to harden. Shit! There was no way he was getting aroused by watching a a dude getting off another dude.
"Puck, seriously, don't!" Kurt could tell where this was going to go if it didn't stop soon.
"This is turning you on, isn't it? So take it."
The grinding picked up speed. The friction was almost unbearable, as Kurt's hips bucked with a mind of their own into Puck's.
Kurt felt himself get closer and closer to orgasm. This was not happening! He was about to come in front of the entire Glee club, who had by now all noticed and stopped singing. A few, Mr Schuester included, were looking resolutely in the opposite direction. Some of the girls were watching with unrecognisable expressions on their faces. All had their legs crossed. But the thing that pushed Kurt over the was the sight of Finn desperately trying to hide his hard on whilst trying to jerk himself off through his pants.
With a loud cry, Kurt came in his skinny jeans, and collapsed on the ground, gasping for breath. His face was bright red.
His eyes met Finn's, who gasped loudly as he also came rapidly in his pants. Everyone turned to look at the souce of the noise.
Puck stood back to admire his handiwork. "Nobody questions my badassness," he said, as he strutted from the room.
Kurt remained seated on the ground, still trying to catch his breath. Finn got up and ran to the boys' bathroom.
Mr Schue stood and, still looking at the opposite wall, announced, "I think we'll leave it there for today." He left as hastily as he could.
Everyone else sat still in shock, until the silence was broken by Brittany whispering to Santana, "That made me so hot." And whilst no-one said anything out loud, everyone else in the room silently agreed with her.
Original Prompt from Glee Kink Meme: Everyone's goofing off at rehearsal one day when Puck jokingly does some groin-to-groin grinding with Kurt. Kurt gets turned on and begs him to stop, but Puck is just like, "Take it, bitch!" and keeps going. Kurt has an epic orgasm. Like, he comes spectacularly in his pants and shrieks and loses the ability to breathe and stand. Naturally, the rest of the Glee Club – including Schuester – notices. Bonus if Finn takes one look at Kurt gasping on the ground and comes in his pants, too.
