Cassidy & Alex: A Love Story

Not that the lust wasn't part of it, though. His right hand, the one on her lower back, was begging, pleading with him to let it slide down and cup her amazing, tight ass. Grab it with a firm grip, and pull her even closer. His left hand wanted just as much to slide from its position between her shoulder blades around front to cup one of her incredible tits. She nuzzled her face further into his neck, and he had never felt so close to giving in.

No. No no no. Summoning up every last drop of willpower he had, he released her from his arms and took a half step back from her. As she lowered her arms, her left hand accidentally brushed against his cock, which was straining inside of his boxers. It was just an accidental glance, but it felt like he'd been struck by lightning. Was it an accident? Yeah, of course it was, don't be stupid.

"Come on in," Cassidy said, still sounding a little out of breath, for some reason. She turned and gestured for him to follow, as he let his eyes wander down to her ass, hugged by her jeans like an old friend. "Sorry the chairs are full; I ran out of places to put boxes. We can sit on the bed, though."

"Sure," Alex said, wondering if he was going insane or if this was really happening. Cassidy jumped onto the bed, her breasts bouncing slightly as she landed, drawing her long legs up toward her body, and leaning her back against the wall. Alex joined her, sitting with his legs over the edge. "So...how are you doing?"

"I...I'm just...," she had started to say okay, but she had always had a policy to never lie to her brother. "I'm not fine. I feel like my head is spinning, and I don't know which way is up. I'm excited to be graduating and going off to med school, but I'm terrified, too. I've never even been the east coast, and now I'm going to live over there, and I won't know anyone, and the one thing in my life I thought I could count on just crumbled all around me, and what if I made a huge mistake and--"

"Cass...Cass...Cassidy!" Alex said, leaning over and putting his hand over his sister's shoulders. "Deep breath. Breathe. Come on back."

"Okay," Cassidy said, doing as he asked, through an embarrassed smile. She loved how his arm felt around her, and how he could calm her so quickly. If anyone else had done the same, she'd have told them to fuck off, that she had no reason to be calm. But Alex knew her well enough that she trusted him. "Okay. I'm sorry, I'm just a little overwhelmed."

"Of course," Alex said. "Hell, I would be if I were you. Don't apologize. Does anyone else know about all of this?"

"No," Cassidy said, enjoying that he had pulled himself right next to her, their thighs touching. "Just you."

"Who were you talking to on the phone when I got here?" he asked. "I heard you through the door. Mike wasn't trying to weasel his way back, was he?"

"No," Cassidy said, feeling her face grow red, hoping that he didn't hear too much of what was being said from the other side of the door. "No, I was just...talking to Meredith."

"Oh," Alex said, before the implications set in. "Oh."

"Yeah," Cassidy smiled, "she told me. She said not to be mad at you."

"A-are you?" Alex asked.

"No," she said. That was only half true, though, but she didn't want to explain why she was jealous of her best friend. "I like the two of you together. Are you going to see her again?"

"I'd like to," Alex said. He couldn't help but feel a little disappointed that she didn't seem jealous. But why would she, dumbass? "I like her. She's fun. Not like the girls I'm usually with."

"Yeah," Cassidy said, elbowing him. "I think you may have finally found the bottom of the 'shy librarian type' well."

"They have their charms," Alex shrugged. "But it is nice to not have to pretend I've read Neruda, for once. Yeah, I'd like to see her again. At least once before I go."

"So you can fuck her brains out again?" Cassidy blurted, without thinking.

"Cass!" Alex yelled, staring wide-eyed at his sister. "She...she told you?"

"Yeah," Cassidy said, embarrassment starting to settle over her, but not as thoroughly as she though it would. "We talk about everything."

"Well, geez," Alex said, his face red. "I know girls talk, but I didn't think that would extend to stories about their own brothers. So, um...I gotta ask...what grade did I get?"

"What?"

"Well, you know," he said, "it's not often that a guy gets a chance to get honest feedback. So...how did she say I did?"

"I wasn't exaggerating," Cassidy said, with a little smirk. "You fucked her brains out, Alex. She was still revved up when I talked to her. So, gold star, bro."

"Awesome," Alex said, noticing for the first time that Cassidy's hand, the one between them, was resting against his thigh. Oh boy.

"That's what she said," Cassidy said. "That's not an Office quote, that's really what she said."

"And you're okay with all of this?" Alex asked, noticing her fingers had started to drum a little rhythm against his leg.

"Yeah," Cassidy said. "Like I said, I think the two of you are...cute...together. I'm glad you're both happy. Someone should be."

"Cass, shit, I'm sorry," Alex said. "I feel like an asshole. Here I am jabbering on about Meredith when you just got dumped."

"It's okay, Alex," Cassidy said, resting her head on his shoulder. "I really am happy for you. And I'm glad you're here. I can't imagine going through today without you here."

"Are you going to tell mom and dad when they get in?" Alex asked.

"I have to," Cassidy sighed. "They'll wonder why he isn't here. I know what's going to happen. Dad is going to pat me on the head, say 'there there' and hand me fifty bucks before going to go sit down with his 'new' family. Mom is going to start ranting about how all guys are the same and blah blah blah. Probably with her new boyfriend in tow."

"She has a new one?" Alex sighed. "Shit, can't be any worse than the last one. That idiot was younger than me, and kept taking me aside and asking if I knew where he could buy weed."

Cassidy laughed, remembering the last burn-out their mother had dragged to Easter brunch, and how she and Alex had sat in the corner making fun of him the whole morning.

"I've missed you, big brother," she said, patting his thigh and keeping her head on his shoulder. "You're exactly who I need today."

"Glad I can be of service," Alex said, starting to feel guilty again for the thoughts that were pounding through his brain, about the hint of cleavage he could see from his vantage point, and the firmness of the thigh pressed against his.

"I'm serious, Alex," Cassidy said, lifting her head off of his shoulder and looking him in the eye. He had the same eyes she did, and, for the first time, she found herself sinking into them. "You make me feel so safe and...warm. It's been a really bad year, Alex."

"I know, sis," Alex said, reaching out and hugging her close to him. "Senior year is a barrage of emotions and stresses anyway, and you've had more than your share."

"Yeah," Cassidy said, his arms wrapped around her. She never wanted to move from them. She wasn't making good decisions, she knew that, but she still didn't care. And now she felt on the verge of an even worse decision. She knew it was an edge she'd never be on again. By tomorrow, her rational mind, that age-old buzzkill, would reawaken, and she'd realize how stupid she was, and talk herself out of it forever. This was, in all seriousness, her one and only chance to make the mistake she desperately wanted to make.

And so she did, taking a step off of the edge of the mental cliff, and not looking back. She pulled away from Alex, just enough to be facing him again. And then she kissed him, hard. Not the kiss a sister gives her brother, but the kiss shared by two lovers who have been separated for too long.

He was stunned. He almost pulled back, but her lips were so soft against his and, despite everything he knew was wrong about it, it felt right. Without realizing it, he was kissing her back. Her tongue, long and curious, slid into his mouth, and he met it with his own. There was electricity in their lips, crackling between them. Her hand was still on his thigh, and his arms around her, but they didn't move. It was all happening between their entwined lips and tongues, massaging, probing, and exploring.

Cassidy's body was on fire. The energy pulsing between her and her brother was setting off every nerve she had. She could feel her nipples standing erect, and her pussy getting damp. She couldn't believe what she was doing, and she really couldn't believe he was letting her.

Neither of them knew who broke off the kiss first, but they did finally separate.

"Oh...," Cassidy said, catching her breath, "Oh wow."

"Cassidy," Alex said, a look of dread falling over his face as he realized what he'd just done. "I'm so sorry, I don't know what came over me. I...I'm sorry."

"It wasn't you, Alex," Cassidy said. "I kissed you. And I want to do it again."

That was all Alex needed. He moved before she could, locking his lips against hers again. It still felt incredible. Cassidy hadn't realized how long it had been since she had had contact—any contact—with another person. Since early Fall, the only person to touch her was herself. Now, her brother's lips moving against her's, she felt like a drowning woman finally coming up for air. Kissing almost seemed more erotic than if he had bent her over and fucked her like he had Meredith. She could simulate fucking with her fingers and toys; this, along with tango, was something that still took two.

The pulled apart again. She was almost delirious with lust. She had to struggle to form words.

"Alex," she said, barely above a whisper. "I want to ask you to do something for me. You can say yes, or you can say no, but either way, it won't come between us, okay?"

"Okay," Alex said, catching his breath and staring deep into her beautiful eyes.

"Alex," Cassidy said, "tonight, just for tonight, I want to pretend we aren't brother and sister. I want you to pretend I'm not your little sister, and just think of me as a college girl who needs a good release. I want you to take me. I want you to have me. It's been forever since I've been with anyone. I'm lonely, Alex. I want to be touched. I want to be held. I want to be fucked. I don't want it to be with just anyone. I'm not Meredith; I wouldn't enjoy it. I trust you, Alex. I trust you more than anyone."

"Cassidy," Alex said, his whole body throbbing. "God...I've wanted this for so long. But...I don't want to take advantage of you. You've gone through a lot today, and--"

"You're not taking advantage of me," Cassidy said. "I'm not drunk; I'm not stoned. I'm a big girl, if you haven't noticed. I can make my own decisions. I want this, Alex. I want you. Please."

Even if he had wanted to argue more, he couldn't have. The breathy way she said please, the fire in her eyes that he never thought he'd see....

"Okay," Alex said, not believing this was actually happening. "Okay, but one condition."

"What?" Cassidy said, a wide smile on her face.

"I'm not going to pretend we're not brother and sister, Cass," he said. "I'm sorry, but I can't. You're not just another horny college girl; you're my little sister. And I love you. Way more than I should. I've wanted you for so long, I can't pretend you're anyone else."

"Okay," Cassidy said, her smile turning wicked. "I like that, too. I can be your horny little sister, then. As long as that doesn't make you hold back. You can do anything you want. I trust you."

It was something she never would have said to Mike, even though she'd trusted him, too. But giving a guy carte blanch just wasn't something you did unless you knew, really knew, that they'd never hurt you. There was no fear in her as her brother lunged, pushing her back onto the bed, kissing her again, and again, and again, one hand running down her side and onto her thigh, the other against the side of her face before trailing down her chin, her neck, and onto her chest, cupping and massaging her left breast through her shirt. She grabbed at his back, pulling his shirt up so she could slide her hands across his bare skin, digging her nails into his muscles. She writhed under him, thrusting her whole body against his in a wave as he pulled at the bottom of her t-shirt. Sliding into a sitting position as they continued to furiously kiss one another, she tore the old shirt off and threw it across the room. It had barely landed before he had her bra unhooked, letting her shake it off of her arms, her breasts finally hanging free.

It was the first time he'd seen them, and he could have been struck dead at that very moment with no regrets. They were perfect, round and full, capped with quarter-sized light tan nipples, which were standing up like top hats as he stared, reminding himself that, for the first time, he didn't have to just look. Indulging the hunger he'd had for ten years, ten damn years, he jumped toward her, his lips landing first on her's, then trailing their way down her neck as his hands stroked and caressed her incredible tits. They felt even better than he'd imagined, firm, but silky, her hard nipples pressing into the palms of his hands as he massaged them.

She moaned as his lips moved from her neck to her collarbone, then down her sternum. He kissed a path down between her breasts, the fine stubble on his face lightly prickling against her sensitive skin, a good, teasing pain that drove her wild. She brought her arms together, pressing her tits closer together, tighter against his face. Taking the offer, he pressed his lips against them, then kissed across her right breast until his mouth came to rest on her nipple. A shudder ran through her as he kissed down once, twice, and then on the third time, let his lips linger, cupped over her nipple as he sucked, gently at first, letting his tongue tease her. It wrapped around her erect tit, flicking gently against it as he sucked, drawing it in a little harder with each passing second.

"Oh God, Alex," Cassidy moaned. "That feels so good."

He responded by pulling his mouth away, only to kiss a trail across to her left nipple, which he began treating to the same ecstasy. Her whole body quivered as he sucked her, and even more so as he hooked his fingers in the waistband of her jeans and tugged them down, over her hips. She wriggled herself the rest of the way free of their confining denim, letting them fall off of the edge of her bed and into a heap on the floor. They shared their next thought, and each grabbed one side of her black satin panties, pulling them off and down her long, dancer's legs, letting them hang for a second on her right toe before dropping down next to her jeans.

"Well," Cassidy said, out of breath already, standing up, naked and glistening with tiny drops of sweat. "What do you think, big brother?"

"Wow," he whispered. It was all he could do. She was amazing, absolutely amazing. Her tanned skin and dark hair, her pert breasts and flat stomach, her fit legs and tight, perfect pussy, crowned with a thin patch of soft, fine hair. He couldn't control himself any longer, not even to take in the raw beauty standing in front of him. He dove at her, pushing her back onto the bed.

"I'm glad you approve," Cassidy giggled as he kissed her stomach, quickly moving all the way down, stopping just above the patch of downy hair. He reached his hands between her thighs, massaging them all the way up, teasing just outside her wet lips with his fingers as his tongue stroked just above her clit. It was driving her wild. She grabbed the back of his head and tried to push him down, but he looked up at her and gave her a mischievous wink. She wasn't going to get off that easy.

He kept kissing her mound, letting his tongue travel through her soft hair, and used his thumbs to run up and down the sides of both of her pussy lips. He could smell the rich, wonderful scent of her pussy, and feel the wetness already working its way out to where he was teasing her. She was ready, and he couldn't hold back any longer. He plunged his mouth toward her velvety lips, running his tongue up and down, starting just above her tight little anus and sliding upwards toward her clit, sliding back down and then repeating.

"Oh God yes," she moaned. "Oh God you're good...oh God oh God oh God!"

"You taste amazing, sis," he said, giving his tongue a brief break before diving back in. She did, too. She was soaking wet, her juices sweet and warm in his mouth as he let his tongue slide around her clit, earning a long, sharp squeal from his little sister. He kept at her, tracing patterns against her clit as his hands slid under her ass, grabbing her and pulling her pussy harder against his face. She was panting now, and held the back of his head with one hand, entwining her fingers in his hair as she used her other hand the squeeze her breasts, trying to grab both at the same time. She couldn't believe how good her brother was at eating her out. She didn't even know it could feel like this. Mike had gone down on her a few times, but it was usually just a few quick licks before climbing on top of her. Alex had moved down from her clit, his tongue probing her, sliding just inside of her and stroking the inner edge of her pussy. She writhed in ecstasy, arching her back, wailing as her brother massaged her in places a tongue had never been. Her thighs tightened around his head, and her body began to shake.

"Oh God," she moaned, closing the hand on the back of his head, pulling his hair. "Oh Alex, don't stop, please don't stop, this is...oh God...you're so damn good! Ohhhh!"

She came, hard, the pent up energy from her phone call with Meredith blasting out of her along with the new rush her brother had given her. She screamed loud enough to rattle the windows, and probably wake up anyone within a two block radius. Her body contorted again and again. Her nipples were so hard they hurt, her pussy was dripping, right into her brother's waiting mouth. Alex eagerly lapped up every sweet, warm drop.

He couldn't believe this was happening. He'd dreamed so many times about being right where he was, never even entertaining the thought that it could actually happen. But there he was, his little sisters' tight, perfect pussy in his face, her juices coating his mouth and on his tongue. And more than that, he'd just made her cum. He never wanted to forget the sound of the first orgasm he gave his sister. Nor did he want it to be the last. Thankfully, she didn't either.

"That was incredible," Cassidy panted. "But you need to fuck me. Right now, Alex. Fuck me! I need you right now."

She didn't have to ask twice. He had his clothes off and on the floor before she'd even sat up, her pussy glistening in the faint light of the moon through the window.

"Whoa," Cassidy whispered as he pulled off his boxers, setting his cock free. It was rock hard and throbbing, hungry for her. She stared at her brother's cock, at how thick and long it was, curved ever so slightly, just enough that she knew it would hit places that had never been touched before. She reached out and wrapped one hand around his, feeling out unbelievably hard it was, letting her fingers dance up Alex's shaft, giving the head a quick stroke with her thumb. He looked down at her, right into her big brown eyes as she leaned in and kissed the tip of his cock, keeping those vivid eyes open the whole time. She let her lips, still tight on his cock, slip down to the top of the shaft. She gave him a gentle, teasing suck, and then drew back.

"Sorry," she said, through breaths, "I want to suck your cock, but I need you inside of me. I need that inside of me. Fuck me, big brother. Fuck your naughty little sister."

He grabbed her hips and set her on the edge of the bed. Her eyes were wild with passion. His cock throbbed when she called him 'big brother', the relation that had once forbidden this very encounter was now gasoline on the fire for him. And, to his amazement, seemed to be for her, too. She spread her legs wide, her wet lips parting, exposing her soft, pink folds.
