Rachel was still drunk, and fairly certain that she and Finn were just blowing off steam, but she was legitimately scared as his tall form and glowering smirk towered over her.
Then he kissed her.
In one motion he pushed her back against the washing machine, grabbed her face with both hands, and roughly crashed his lips down onto hers.
Rachel couldn't tell if it was the alcohol, the adrenaline from their argument, or sheer joy that made her growl against Finn's mouth. When she did so her mouth opened and she felt his tongue slip inside, tentatively at first and then more forcefully, his fingers lacing into her hair.
"You want me to prove that I love you," he panted, breaking the kiss momentarily and then resuming his lips' assault on hers, "and they don't think I can make you come."
Rachel wasn't sure that the two were connected nor why Finn was going there, but she didn't have the wherewithal to interrupt as he kissed down her jaw and began laving at her pulse point, merely moaning in response.
"I love you so much it scares me," he continued, switching to kiss the other side of her neck and up to her ear. "For months I was waiting for you to be ready, so I could show you exactly how much I love you." He whispered the last part directly into her ear, simultaneously guiding her left hand to the bulge in his pants.
Rachel gasped as he kissed her again, his tongue probing as deeply into her mouth as it would go. Sure she'd pressed up against Little Finn incidentally when they made out, but this was her first time touching that area directly, albeit over his clothes. She was surprised when it twitched under her touch and felt a heated sensation growing between her legs. Instinctively she pressed herself against Finn's body, moaning again.
Even with her eyes closed she felt him smirk against her lips, clearly pleased with her reaction. He ran his hands down her sides, returning his lips to her ear. "You don't think I can make you pant and moan and scream my name? Because I've been looking forward to it for so long," he whispered as he snaked a hand to her crotch, rubbing gently.
"Mmmm... Finnnn..." Rachel had never felt this way before. The intensity of his voice combined with the effects of drinking and finally getting to be close to him again were making her dizzy.
Pulling back, he looked into her eyes. She sensed him searching her face for any warning signs not ti continue, despite clearly enjoying his role as the aggressor and the fact that he caught her somewhat by surprise.
Obviously Rachel didn't want him to stop, but she also didn't want to seem desperate. What if Finn was merely channeling his frustrations into this drunken sexual rage and when it was over he'd go back to being a whiny baby who didn't want anything to do with her.
Or maybe the others were right, and she just needed to loosen up. Settling on that answer, she reached for the hem of her sweater and pulled it up over her head.
