I tried to base this off of as many spoilers as I could, so I hope it comes out right. Uhh, enjoy? If that's even possible, ahh.
Kurt stumbled out of the bar tugging Blaine along beside him. It was nearly midnight on a Friday night, and both of them had drank more than they should have. Kurt offered to be the designated drive, and only had two drinks; Blaine on the other hand was completely wasted.
"Where we goin', Kurt?" Blaine slurred, holding onto Kurt's arm tightly. "T'was awesome in there. W- we gotta go back."
Kurt was a little bit frustrated with Blaine right now. He sighed. "We're going home. You're drunk, Blaine. We can go back another time maybe."
"Pshh I'm not drunk! I'm juss having fun." Blaine leaned on Kurt more- almost tripping over his own feet.
It wasn't that Kurt had a problem with Blaine drinking –that wasn't it at all- it was that Blaine had promised not to drink too much and had obviously broken that promise. They finally approached Blaine's station wagon and Kurt unlocked the backseat door.
"Here," he told Blaine- who was now completely draped over Kurt's shoulder, leaning on it for full support. "I'll help you in."
"Wh- what am I doing back here? Imma big boy, Kurt. I'm big enough for the front seat," Blaine protested.
Kurt couldn't help but to laugh at Blaine joking about his own height. "I know you are, but I think it'd be better if you lied down, okay?"
"Mmkay," Blaine gave in rather easily. He let Kurt help him, but he pulled Kurt in alongside him.
Kurt practically fell onto Blaine's lap. He started to get up but Blaine pulled him back down. "Blaine, I-"
He was cut off when Blaine pressed his lips firmly to Kurt's. Kurt was surprised at first, but after a few seconds he melted into it. The kiss was sloppier than usual -seeing how they had both been drinking- but it was still so good.
Kurt lost all train of thought about what he had been saying a few seconds ago. Instead of thinking, he opened his mouth slightly and waited for Blaine to do the same. It only took a second before their tongues were fighting for dominance, but Kurt won this time. Blaine groaned hungrily into Kurt's mouth and his hands found their way to Kurt's hips before he shifted so they were lying down- Kurt on top of his chest.
Kurt moaned at the contact and pressed himself closer to Blaine. He reached one of his hands up to Blaine's hair –which had already become ungelled from the events of the night- and would his fingers through his curls, tugging tightly. The other hand he had placed on Blaine's chest, was now slowly trailing its way down, stopping at the top of Blaine's slacks.
Blaine shivered at Kurt's touch, and he squeezed the other boy's hips tighter. He loved it when Kurt was touching him. He pulled away and started kissing down Kurt's jaw.
Kurt could already feel himself getting hard in his skinny jeans and he silently cursed himself for wearing them tonight. Blaine was sucking and lightly biting at a spot on his neck, "O- oh god, Blaine," he moaned.
Hearing Kurt moan his name made him instantly harder. He pulled away from the other boy's neck –breathing hard, "Kurt youaresohot," he slurred, hands now roaming the other boy freely, grabbing everywhere possible.
Blaine was very handsy when he was drunk- Kurt knew that now. He didn't mind all that much, he just didn't want things to get carried away, not when Blaine was drunk.
Blaine flipped them over, so that he was on top of Kurt now, and he straddled his hips. He leaned down, kissing Kurt firmly once more, before sitting up and reaching down to the button of Kurt's jeans. His hands fumbled for a minute, and before he knew it Kurt's hands were on his.
"Whoa, w- what are you doing?" Kurt managed to shift Blaine off of him so that he could sit straight up.
Blaine frowned at the loss of contact. "I love you, Kurt. A- and I want to make love to you. So bad. I want to make you scr-"
"Blaine, Blaine..." Kurt cut him off; he couldn't stand to hear any more being as hard as he already was. "I can't. N- not like this. We've both been drinking and I don't want to do that like this."
"But I-"
"No!" Kurt yelled, perhaps a little too loud. "I'm not having sex with you tonight," and he opened the door to get out of the car.
Blaine groaned and followed him out of the car. "I'm not that drunk, Kurt." He was starting to get really frustrated. Why couldn't they just have some fun for once? "Maybe it's not sex that you don't want. Maybe it's just me that you don't want." Blaine knew that wasn't true, but the alcohol was making him think illogically.
"What?" Kurt gaped at him. "Blaine, stop being ridiculous. You-"
"Oh, so now I'm being ridiculous? Great. That's just perfect." He turned around to start walking away but then paused, turning back. "You know what? I'll find my own way home. Just take my car, I don't care anymore." And he turned around again and stormed off across the parking lot.
"Blaine! What are you- Blaine! Come back!" But Blaine didn't listen, and Kurt's legs weren't working to chase after him. What the hell just happened? One minute things were fine- great even- and now... Now what was this? Kurt was left just standing there, having no idea what to do.
