Back From College [MF, Incest, College]

“I can’t wait to come home and see you!” Marie squealed on the phone to her little brother. It would be her first time back home in almost two years. “You’ve grown a ton in the year I’ve been away at college!”

“I’m pretty much the same, sis.“ Nathan replied. Others thoughts occupied his mind, like how much his sister had grown in the last year. He never really noticed it before but she was so beautiful. Small in height and weight – 115 at most, blonde hair, she only came up to his chest, thin waist and C cup breasts (he’d done her laundry a couple of times when Mom asked him too). She even had a touch of six-pack abs on her stomach from her gymnastics days. Her best feature though, in Nathan opinion was her butt. She had an ass that guys loved – big, round and filled yoga pants like none other. Put a tight g-string on that ass and you’d have heaven.

Late at night before bed, she’d often wear short spanks from her cheer days, even when guests were over. Several of Nathan’s friends were often caught staring at her by Nathan, but only because he would be staring too.

“Oh I highly doubt that! You’re in the middle of a growth spurt. You’re taller than Dad now.” Marie chided.

Nathan just chuckled, “I am. Have been actually. I put on almost 30lbs since my last football season too. I’m at 175 now.” It wasn’t huge for football players, but Nathan was only in his sophomore year of high school.

A slight pause on the other end of the phone before Marie blurted out, “You fatty! Guess you’re getting pretty strong now, huh? I’ll just have to wrestle you and test it out!“

“Won’t be much of a match, sis. You know I’ll win!” he retorted. “But I’m game for the challenge!“

Marie laughed, “Good! Then I’ll see you at home in a few hours. I gotta run though! Love ya, Nate! Tell mom and dad I said hi!”

“Love you too! Will do!“ The phone clicked and Nathan was left alone with his thoughts. Jesus, I gotta stop thinking about her like that, she’s my sister!

He sat down at the kitchen table and tried to occupy himself with a little bit of homework, but his dick was just so rock hard his thoughts kept wandering. Looking around to make sure his parents weren’t in the kitchen, he slid his hand down his pants. Gripping his cock full with his hands, he started squeezing and stroking it. This has gotten bigger too, sis.

“Oh hey Nathan!” Mom burst into the kitchen with some cleaning supplies and rubber gloves. “I didn’t know you were in here, I thought you went out with friends?”

Nathan’s hand whipped out of his pants, leaving an unsatisfied cock in its place. “Uh…yeah, I remembered I had some homework, so I kinda had to bail on them.” Fuck, he thought, that was close.

“That’s a bummer,” Mom said as she opened up the oven and started spraying some cleaning liquid in there. “Good for you, getting your homework done.” She bent over and started wiping the inside of the oven.

Oh fuck, that’s where Marie gets it! I need to get out of her before she sees. Nathan stood up suddenly, nearly knocking his book off the table, before grabbing all his homework in one swoop and rushing out of the kitchen mumbling something about needing to use his computer upstairs.

Once he was in his room, he quickly closed the door, locked the doorknob and dropped his pants, letting all 8 inches of his dick pop out in front of him. He rushed over to his computer, tapped a few keys and pulled up some porn videos.

I am so fucking horny, this is ridiculous, he thought as he started to stroke his dick.

He remained unsatisfied though. He pulled up video after video of hot MILFs with giant tits and slutty bimbos, but they all seemed…off for some reason. It wasn’t until he came across a video with a petite, blonde white girl deep throating a huge black cock that he started feeling the rhythm; the gentle rise of cum in his balls.

He stroked his cock hard as he watched the petite slut suck and slobber on a giant black cock, drool dripping onto her small, perfect tits. She didn’t care, she wanted cock down her throat.

Like a good dutiful slut, Nathan mused.

“Uh…fuck….y-yes…ahhh” Nathan groaned as he neared climax. The BBC in the video was throbbing, about to feed the girl some cum.

Nathan thrust his hips in time to her pretty mouth going down on the dick. Another throb, and again. Here it came. The man on-screen moaned softly, hitting his climax.

“Oh my god…uhhh!” Nathan moaned, probably a little too loud. His own cock throbbed uncontrollable. “Suck that big cock…suck it…suckkk….itt…Marie!” His voice caught a little as he realized he just moaned out his sister’s name but waves of pleasure battered the apprehension away. It felt like hours that he rode those waves, warm cum shooting out of his cock and all over his hands and thighs.

Breathing heavily he looked down and realized he had finished everywhere. Usually, he caught it in his other hands or laid a towel down. He totally forgot to this time.

I came that much?! He couldn’t believe how much cum was in his lap and on the floor. Damn, he thought with a smirk. Physical relief flooded through him as he slumped back against the chair, but mental relief was far away.

“I just came to the thought of my sister sucking a BBC.” he whispered. I better keep this under wraps, really well.

He dreaded having to look into his sister’s eyes when she got here. He glanced at the clock suddenly, unaware of how much time he had spent looking for a video. 3:25pm. Marie wouldn’t get here until 3:45pm, he had time to clean up.

*knock knock* Nathan jumped as someone knocked on his door. Mom’s voice preceded after, “Honey? I’ve gotta run to the store before Marie gets here but I also need to stop by Jen’s house. I may be gone a while. Need anything?”

Clearing his throat before he spoke, “No I’m…uh, I’m good! Thanks though!” he called back.

“Okay, see you when I get home! Call me if you leave, okay?” she said sternly.

“I’m not planning on leaving but okay!” he said. I definitely need to clean up.

He heard his mom’s car start and pull out of the driveway. He immediately rushed to the bathroom to grab some towels, not even putting on clothes, his cock swinging freely as he ran, cum dripping down his leg.

He just finished wiping up the cum on the floor and his lap, pulling some underwear on when the doorbell rang. SHIT! She’s early?! He whipped on some pants, and ran downstairs without a shirt on to answer the door. Marie stood on the other side, looking around at the new decorations Mom had put up for spring. God she’s so beautiful, Nathan thought. She wore a light pink, floral sundress with a low neckline, it stopped mid-thigh and had an open back. Nathan had seen the dress before. She wore it only when the weather was especially nice.

He opened the door hesitantly, acting like he didn’t know who was on the other side and was greeted by a big smile. Marie’s thin pink lips curved up to reveal perfectly white teeth. His mind went immediately to the video of the petite blonde girl taking that black cock in her mouth. I bet Marie would look amazing with a huge dick in her mouth. He shut down his thoughts as he opened up the door wider, exclaiming loudly, “Sister!”

She stepped into the doorway and as she yelled, “Brother!” back at him she leaped at him in a massive hug.

Taken by surprise, Nathan fell backwards, his sister half-wrapped in his arms. They fell straight to ground, Nathan still in shock as Marie laughed maniacally on top of him. “Told you I’d wrestle you!” she chirped, straddling his left hip.

Nathan cracked a devious smile, “We haven’t even started!” he said as he grabbed her shoulder and rolled her to the right, so that he was on top and had her arms pinned on either side of her head. “You haven’t got a chance.” He leaned in to emphasis his control.

“Okay so maybe you’ve gotten a little bigger.” she conceded below him. Her hair was thrown about wildly, her dress pulled up slightly on one side, revealing her toned legs and inner thigh. She’s got to be the sexiest woman alive. She has to be, Nathan thought.

“But you know, I’ve got some tricks myself.” She suddenly bucked her hips up, taking Nathan by surprise, obviously planning on throwing him over her head. Instead, Nathan’s new weight took her by surprise and instead of going over her head, his face went straight into her cleavage. He felt the soft press of her breasts, oddly warm against his face.

There’s only one layer between her breasts and my face, which means…she’s not wearing a bra! I just motorboated my fucking sister!

The thoughts raced through his mind at the implications at lightning speed, triggering biological responses he had zero control over.

“Omph!” was Nathan’s muffled grunt as his face buried into Marie’s breasts. Suddenly realizing what happened, he practically jumped back to standing, blushing harder than he ever had before. “That’s awkward,” he tried to joke. His face flushing even more as he saw her smile. He quickly looked at the floor.

She was still on the ground, but picked herself up. Still smiling she said, “It’s not awkward, Nathan. We’re siblings. I’ve seen you naked before.”

“When we were toddlers!” he exclaimed. He got no response, so he looked up to her face, except she wasn’t looking at him, she was looking down at…Oh god.

Marie had her eyes transfixed on the giant bulge in Nathan’s pants, so big it was practically bursting out.

Fuck, I didn’t notice I had hard-on! Her eyes flashed up and met with Nathan’s, who swallowed hard. He immediately started for the stairs to his bedroom when she caught his arm.

“Let me see it.”

“What?” he asked incredulously.

“Let me see your dick. It must be huge.” she said as she walked around to the front of him and bent over, leaning in closer to it.

“I…uh…what?! No.” Nathan cried. He tried to stammer out some excuse, fumbling over words and blushing twice as much as he thought was possible.

“Okay okay, I was just curious. Head up to your room and do whatever you gotta do, I gotta unpack anyway.” Marie said with a hint of scorn. She smiled and then turned to go back outside. Nathan’s eyes dropped as she turned, catching sight of her ass swaying as she walked back to the front door. Nathan stammered and then bolted off to his room.

He closed the door and took a deep breath. Well that was something. My sister saw me get a hard-on because of her! I’m screwed! She won’t tell anyone, will she? He stomped over to his stack of books and grabbed the first on top. Trying to distract himself and act natural, he began to read each word with painful precision, as if each word might contain the key to ending his embarrassment.

Two pages in and suddenly the door opened. I forgot to lock the door, dammit! But before he could get up, the door swung all the way open, revealing Marie in a dark purple thong. She wore no bra, revealing her perfectly shaped breasts with smooth skin. They had a gentle tan line from her bikini top and small, perky nipples that Nathan could see from his bed, were erect. Her bottom was a thin mesh pantie with just a little patch of fabric covering her pussy, the soft fabric curved in as it got to her labia, just a hint of her cameltoe showing. She stood in the doorway with one hip pushed out, hand on the doorframe and a wicked slutty smile across her face.

“Er…” Nathan tried to say something but his throat caught. Probably due to the blood rushing to his cock, which was now fully erect again in his pants, pleading to be let out. Traitor!

Marie walked into the room, each step slow and deliberate, letting Nathan drink in every inch of her body. “I got these for my boyfriend but I haven’t worn them for him yet.” she said seductively. Her boyfriend lived back in the town where Marie went to school.

She leaned in, putting her lips right next to Nathan’s ear. “But I think I need a second opinion.” A pause. “Plus, I got to see something I like, so I’m just returning the favor.” Marie stood up, and then swung a leg over Nathan’s hips, so she was straddling directly over him.

“Marie…I uh,…what if…?” Nathan had only just started breathing again.

“What if what? Dad’s out of town. Mom’s at Jan’s – I just got off the phone with her, I told her she could stay cause I wouldn’t be home until 6pm.” she leaned in until her breasts were directly in his face again. “Do you want to feel what it’s like to really experience a woman’s tits in your face?”

Nathan’s hands found themselves groping her boobs, one in each hand, before he even knew what he was doing. This is my sister! I can’t…I can’t do this!

Marie suddenly wrapped a hand around the back of his head and pulled his mouth directly over her nipple. Nevermind, I can totally fucking do this, he thought as he sucked hungrily on his sister’s perky nipple. Marie moaned loudly as his hands started squeezing her tits and he pulled more into his mouth. His hips started thrusting slowly in time with hers. Her panties growing increasingly wet with each touch.

“Now show me that cock.” Marie moaned as her hands shot down to his pants. She crawled back to his knees and expertly undid the button and zipper. She yanked his pants down to his knees and his cock shot out and slapped against his bare stomach. She started, stunned for moment by the incredible size of her little brother’s now grown dick. Marie’s smile grew even wider before her mouth opened longily. “Please baby brother, can I taste that big cock?” she said with a playful pouty face on. “You know I love big cock, it’s my favorite.”

Fuck yes. She’s gonna deep throat my cock like she does those college boys. I know she gets lots of dick at college. Marie always was a party girl. He wouldn’t be surprised if she ever got too drunk and let a couple frat boys use her like a fuckdoll.

Nathan gave her a nod and a smile, saying “Yeah big sis, you can suck my dick.” But before he finished his sentence, Marie had grabbed his dick in her small hands and was stroking it. She put her mouth to tip and gave it sloppy, tongue kiss all while staring into Nathan’s eyes. Her saliva dripped down the side of his dick before she chased it with her tongue. Slurping loudly, she flashed Nathan a quick smile before turning her mouth over the top of his dick and lowering herself down.

“Holy fuck….jesus” Nathan moaned as Marie’s mouth took in inch by inch of his dick until her nose was pressed against his stomach. She just fucking deep throated ALL of my dick. She took her time sucking all the way the back up with a loud ‘SLURP!’ at the end. “I’ve never experienced anything like that before, Sis.” Nathan said in between heavy breaths. “That’s fucking incredible.”

Marie giggled, looking so adorable with a big cock right next to her face. “I told you I had some tricks!” She went back to sucking on his cock, taking her time and letting Nathan climax a couple times, but never cum. She always stopped when he got close.

“Marie, just let me cum in your mouth, please.” Nathan begged.

“No, baby brother, I’ve got a different plan.” She stood up on the bed, letting Nathan look all the way up her body, but his eyes settled on the spot right between her legs that was dripping wet. Marie peeled her panties down slowly, bending forward as it got to her knees. Once they were off her feet, she winked at Nathan and walked over to the door, panties in hand. What is she gonna do?

She giggled again as she put her panties on the doorknob – on the outside doorknob, and closed the door. “I like some risk,” she teased.

Nathan didn’t think he would say no to her even if their parents were standing in the doorway right then. “Okay, I like risk.” he said as she laid down next to him.

“I want you to get on top of me, baby brother. Show me you’re a man now.” She spread legs and put her hand on her pussy, rubbing gently.

Nathan slid over, letting her get in the center of the bed. She spread her legs even wider, letting him see a full view of her beautiful, shaved pussy. It was so wet, some of it running down to the bed. Kneeling in front of her, dick erect, Nathan leaned forward gently. With one hand, Marie guided his monster dick to her pussy and with the other hand she ran her fingers through his hair. “Take me.” she said defiantly.

Nathan pushed his cock deeper and deeper into his sister. She obviously wasn’t a virgin, but she was still incredibly tight. “Ohhh! Uhhhmmff!” Marie moaned so loudly anyone in the kitchen could have heard them. Nathan was breathless from the feeling, his brain so full of ecstasy as his slid his cock in and out of his sister. She stared up at him with eyes of longing and hunger, her perfect body laid open before him like a feast. She welcomed him into her, all of her.

He shoved his cock harder into her, shaking the bed and banging the headboard against the wall. Laying his head on her breasts, he breathed in time with her, holding her close and she pulled him into her. Marie cradled his head against her boobs and wrapped her legs around his hips. “You’re mine,” she whispered. “I’m yours and you can have me whenever you want.”

At that Nathan was pushed over the edge. He closed his eyes and thrust again as he orgasmed. His cock throbbed, pushing his cum into places her boyfriend had never touched. He filled her to the brim and knew that cum would spill out as he exited her, but he never wanted to leave. He thrust one last time as he stared into his sister’s eyes. She held onto his face and kissed him with force, pushing her tongue into his mouth. “I love you, Nate.” she said.
