A/N: Sorry for the huge delay. My computer crashed and I had to completely re-write this chapter.

By the way, there are going to be those of you who find this weird. I'm well aware of that. I've never written these characters together before and I found it a bit challenging. But it's all for the sake of the story!

Honestly, the night with Kurt and Mercedes was a total accident.

Kurt invited her and Mercedes over to watch The Rocky Horror Picture Show before they put it on at school. They'd all seen it, of course, but they figured a little refresher was never a bad thing. They all changed into pajamas and locked themselves in Kurt's basement room to watch it.

Rachel had seen Rocky Horror five times in the past two years, and it wasn't because she thought the plot was spectacular. It was kind of embarrassing, but she always got a little horny watching Janet run around in her panties. She couldn't help it. And then the water scene at the end of the floor cabaret, with all of them twisting and groping each other... it was almost too much. She inevitably ended up in her bedroom with one hand down her panties and the other gripping her own breast, moaning out Janet or Brad's name when she came.

Watching the scene now, Rachel wondered if she might be able to touch herself under her sleeping bag once Kurt and Mercedes had fallen asleep. It was always risky, doing this at sleepovers, but she'd done it before (once at Brittany's after remembering their evening in the choir room, and once at Quinn's when picturing the other girl naked and wet).

If she'd been watching, she might have noticed the way that Mercedes' eyes glazed over halfway through the movie or the way that Kurt licked his lips when he saw Rocky.

After the movie, Kurt surprised them both by pulling a bottle of vodka out from behind his bookshelf. "Just a little treat for us," he said slyly, pouring double shots for each of them.

Four shots later, Rachel was completely wasted. Kurt and Mercedes were giggling and falling all over each other.

"Kurt," she slurred. "I have a question for you."

"Yeah?"

"Yeah. So. I know you're gay, right? But like... do you ever get turned on by girls?"

Kurt laughed. "No!"

"Really?" Rachel made a face at him. "Like, not even a little? Because I totally do."

"You do?" Mercedes giggled.

"Yeah! Like, did you see Janet in that movie? I mean... I don't know. She's got great breasts, don't you think?"

Mercedes choked on her fifth shot.

"Come on. Don't even tell me you wouldn't get in bed with her if she asked," Rachel argued, feeling her head spin.

"I wouldn't. No way," Kurt said defiantly.

"Me neither," Mercedes chimed in.

Rachel got up on her knees and crawled the few feet to Mercedes. "Seriously, you've never even kissed a girl. You don't know how great it is."

"What, and you have?" Mercedes nearly shrieked.

"Uh huh," she answered, before kissing Mercedes squarely on the mouth.

Maybe it was the vodka, but the other girl didn't push her away. She let the kiss deepen, moaning a bit into Rachel's lips.

"Oh my god," Kurt giggled.

And then Rachel was pushing Mercedes backward onto Kurt's floor, pulling at her pajamas with clumsy fingers. "Rachel! What are you doing?" she squealed.

"You clearly need to learn the fun way that girl on girl is awesome," Rachel chirped. She pulled the girl's top off, bending over to pull one of her huge round tits into her mouth. Fuck. They were bouncy and juicy, the best tits Rachel had ever seen.

(And she'd seen more than you might have thought. Sure, she acted like a prude, but that wasn't to say she didn't watch her share of filthy movies.)

She buried her face in them, licking everywhere as Mercedes giggled underneath her. She shook her head, watching those enormous tits bounce around, feeling herself getting a bit damp. Then the pajama pants were gone and Rachel was dipping her tongue to the other girl's slit, pushing deep within her and hearing a high-pitched cry. She grinned in satisfaction, swirling her tongue around Mercedes' clit. "You like that?" she asked coyly.

Two hands twined into her hair, and Rachel felt her head pushed harder into Mercedes' mound. "Mmhmm," Rachel hummed, letting the vibrations move through her pussy. "Mmmmm."

It didn't take long before Mercedes came into Rachel's mouth, wetness seeping around her lips. "Oh my god, Rachel," the girl moaned, and Rachel lapped up her juice eagerly.

She looked up to find Kurt watching with a bewildered expression. "Just wait. You're next."

"No way," Kurt said, backing up. "I like guys."

"Come on. You didn't find that the least bit attractive?" Rachel asked, standing up so that they were eye-to-eye. She pulled her shirt over her head, exposing her bare breasts. "You don't find me attractive at all?"

She looked down and saw the tiniest hint of a bulge in his pants. She raised an eyebrow at him.

"Fine," he snapped. "It was hot, okay? I just... I can't get any more confused than I already am."

Rachel stepped forward and kissed him, tasting vodka on his tongue. She pressed her boobs into his chest. "Come on, Kurt," she whispered. "You know you want to."

He growled, and suddenly they were both on the floor. Her shorts were being dragged off of her with ferocious hands, and Kurt was positioning himself behind where she knelt on the ground.

"Fuck me, Kurt," she breathed. "I want it. I'm so wet."

He groaned as he pushed into her from behind, taking it slowly at first, and then pounding harder and harder. Mercedes watched from in front of Rachel, fingers wandering toward her slit and rubbing it lightly.

"Kurt," Rachel panted. "Harder. Harder!"

He slammed into her, his cock hitting deep places within her. Rachel felt as though her head might explode. She reached back with one hand and stroked her clit. "Yes, yes, oh god!"

She came so hard that her arms nearly gave way. She wobbled precariously as her pussy clenched down around Kurt, squeezing him so hard that he came just seconds later.

They both collapsed on the floor, and the three of them fell into a drunken sleep that night. When Rachel woke up around seven, she hurriedly pulled on her pajamas and snuck out the door before either of them could notice.

It was her first walk of shame, but it wouldn't be her last.
