Kurt slowly got rid of his pants and Karofsky's.
"I like action better than begging", the soprano managed to say, through harsh breaths, and took off Dave's underwear, exposing the beautiful – and already hard – cock.
It was the first Kurt was seeing a cock in real life, and it actually made him feel a bit insecure that he was staring too much.
"Don't stare at it, Hummel. Suck it", Dave said, almost demanding, and Kurt felt his heart pounding. What if he did something wrong? "This is your first time, huh?"
Ashamed, Kurt nodded with his head down.
"So I guess I'll have to show you how to do it", Karofsky said, raising Kurt's head and facing him. "I'll sit where you are and you just take it in your mouth"
They changed their positions, so that Karofsky was sitting on the sink and Kurt was standing in front of him. He did as Dave said: took the dick into his mouth and started sucking it slowly, teasingly, and the other boy started moaning and trying not to scream.
"Fuck", Dave muttered. "God, I just, fuck, I need to feel you", he begged, and Kurt smiled.
"Who's the one begging now?", Kurt teased, and Karofsky moaned.
"M-me", he stuttered.
"Get down on your knees and beg me", the soprano demanded.
