Julie Takes Her Brother By Surprise

By: rhylym



"Hey baby brother," Julie said as she knocked on Mark's open door. "Ya got a minute?"

"Yeah, I guess. What is it?" Mark replied on the edge of annoyance. He hated when his sister, who was only a little over a year older than he was, called him 'baby brother'. Julie was 20 years old and about to leave for college after getting her two-year degree. Mark was 19 years old and on the same program as Julie, but a year behind. 

She came in and flopped down onto his bed. He looked over at her from his seat on the floor by the window and she smiled at him. A sly smile, waiting to see if he would say anything about her calling him 'baby brother' on purpose. He didn't. This time he simply ignored her, much to her dismay. She loved getting a reaction out of him.

"What?" he said again.

"I was wondering if you were going to say goodbye to me. I leave in a few hours, you know."

"Yeah, I know. I was going to see you off when you leave."

"Well, that's a relief. I'm going to miss you Mark."

"Yeah, I'll miss you too."

"Mom and Dad aren't here right now, you know."

"Yeah, I know, but they'll be back before you leave."

"Oh, I'm not worried about that. It's just...I've always wondered, did you ever hear rumors about me, like around school or anything?"

Mark looked back up at her, "What? No, not really."

"Hmm, I'm surprised."

"Why?" Mark asked.

Julie shifted on the bed and lowered her head, but still keeping her eyes straight on him. "Because I probably fucked about half the guys in school," she sighed.

"Oh God...ok fine, I heard that you were a slut who sucked for days and I could've figured it out even if I hadn't heard anything around. That's what they said anyway, but I never thought of you like that. Even if it was true."

"And you never said anything to me?"

"No, why should I? What was I supposed to do about it? Would you have listened to me if I said you should stop?"

"That's so sweet," she said. "Mark can I ask you something something else? This is more personal."

"Alright, what?"

"Are you a virgin?"

"Jesus... Julie. Why would you ask me something like that?" She kept staring at him, waiting for an answer. Her face revealing nothing, just a dull void waiting for information. 

"Fine yeah, I am, ok?"

"Oh Mark honey, why? You're a such cute guy, you should be able to have lots of girlfriends or at least to get laid once in a while."

"I dunno. Sometimes I get nervous around girls. And it's not like I've never done anything, I've just never gone all the way."

"Not very much though, huh?"

"No," he told her. He looked down and shifted his weight, trying to find a more comfortable position for his legs.

"You never get nervous around me, though?" she said, leaning down to him to catch his eyes again. 

"Well duh, you're my sister, it's completely different. I've known you my whole life."

"Do you think I'm pretty?" she asked. She dropped her voice to a soft hush, "do you think I'm sexy?"

"Sure, you're pretty. You're a pretty girl, but I never think about you like that or look at you that way."

"Oh never, not ever?" She got up onto her knees, her body swaying from the motion of the bed. "You never checked out these big tits?" she teased as she put her hands over her breasts and caressed them. "You never imagined coming into my room and sticking your big cock right here between my tits?"

Mark giggled, "No, man you are silly."

"Is that a boner I see there little Marky, does Marky have a big boner about his sister's titties?"

Mark frowned, "No."

"You did though, I saw it. Where'd it go? Did you cum in your pants?"

"I didn't," Mark said and blushed bright red at his sister's teasing.

Julie went to the doorway and closed the door. Mark noticed that she was wearing very small and very tight athletic shorts that were molded to the contours of her ass. He also noted that her thin, white V-neck T-shirt barely contained her breasts. Julie was dressed even more provocatively than usual.

Julie turned her back to the closed door. She got onto her knees and slowly began crawling toward where Mark was sitting on the floor. He had a marvelous view down her shirt into the valley between her breasts and he became fully aroused in spite of himself. She stopped in front of him and reached for his crotch. Mark was frozen as her hand approached him, but he recoiled at her touch.

"I knew you were super horny for me, baby bro," she whispered. She kept crawling forward aggressively and in response Mark began to ease back until Julie was hovering over him. 

"I don't think you should need to be a virgin anymore." She pressed her breasts onto Mark's chest. "You want that? I will fuck you right now."

"Oh God," Mark gasped. "I..."

"Relax, little brother, let me take care of you." She nestled in against him and kissed him, she felt him push his dick up against her and she let out a soft moan. "That's it Marky, use your cock on your sister." She felt his hands cup her ass and she kissed him harder. "Yes, massage my ass."

"It feels so good."

"I want to suck you. I'm going to put your cock in my mouth." She catapulted off him and grabbed at his pants, working her hands quickly to get his zipper down. She took hold around the base of his cock and shoved him inside her mouth in a quick fluid motion.

"Oh my god, wait, oh...suck it, don't stop, suck my cock, Julie."

She sucked her brother with firm pressure that made a popping sound as she came off the tip of his cock before gulping him in again. She slurped at his cock with loud unselfconscious sounds, letting every movement she made on him be matched with a loud exclamation point. Ever so gently, Julie caressed Mark's balls with her fingertips as she sucked his shaft deep into her mouth. He was softly groaning incoherently with his eyes rolled back in his head. She peeked up at him and gave his balls a playful squeeze to make him groan louder. She resumed her slurping against his dick and kept taking him deep.

Mark started finding words again as he neared climax, "Jesus, fuck Julie, I'm going to blow it in a second. I'm about to fucking cum in your mouth."

Coming up for air Julie heaved, "Pump it into my throat, mmm, I'm gonna swallow it all. Jizz in my hot mouth." She planted herself back on his cock and fucked him with her mouth, slamming her head up and down on him.

Mark tried to hold it in because it felt so good, but he no longer could. "OK, ok, ok, here it comes, I'm cumming," he said as he began to shoot streams of jizz into his sister's eager throat. Julie kept him deep within her mouth near the base of his cock and let the first strong spurts hit the back of her throat. Then she slid up his shaft, keeping her lips sealed around the head of his cock and helped pump the rest of his cum out with her hand as Mark twitched and panted.  

"See, fun huh," she said as she swallowed the rest of his load and wiped her mouth with the back of her hand. "Ever get such a suck, Mark?"

"Not like that. Wow."

"Well, I still want to fuck you before I get going. Anyway, you're still a virgin so I haven't even kept my promise yet. It's getting in a pussy you still need to do and I'll never forgive myself if you have to keep being a virgin for much longer. Not on my watch. 19 years old is plenty old enough to get some pussy, eh?"

"Why do you have such a keen interest in if I'm a virgin or not all of a sudden?" Mark asked.

"No real reason. It's only that I won't be around much anymore and this is the last chance I have to help you. Any day now some other girl could get to you and I don't want that to happen since it's not too late. Actually, I'm so glad that I get to deflower you. For me to be the first pussy that you get to stick your dick into...that is a thrill and kind of an honor. Ya know? Sometimes I would fuck guys that kind of look like you and I'd imagine it was you inside me instead of whoever. I guess I've dreamed of this for a while now, so...I want to make it count for both of us."

Mark was resting on the floor with his pants around his ankles, still catching his breath. Julie found the cuffs and started tugging at them, shaking the pant legs and lifting up. "But anyway, get these off and take off your shirt, we don't have all day here."

Julie began to undress quickly, but not in a hurry. Mark just admired her body as she took off each article of clothing. When Julie was totally naked, Mark slipped his shirt off over his head and then he was naked as well. Julie marched over to him, her tits jiggling with each step and took him by the hand. She pulled at him, prompting him to get up and she guided him toward the bed. Mark bounced and his limp dick swung as she pushed him onto the bed.

"Come on, get hard again," she scolded. She got onto the bed with him and got beside him, pushing her ample breasts into Mark's arm. "Will this help?" she cooed as she leaned over him, brushing her tits against his chest and kissing him on the mouth. Mark put his arm around her and leaned up, kissing her back and feeling her smooth skin across her back. Julie reached down for his cock. "Yeah, that's working," she said, sounding satisfied at his progress. She stroked him until he became fully hard and took position on her back. She spread her legs wide and said, "get inside me, brother. Come and fuck your horny sister for all you're worth."

Mark got between Julie's spread apart legs and looked at her. "Hey bro, you got a condom?" she asked. 

Oh, uh, no I don't," he said, looking around as if one might have been hanging down from the ceiling on a string. He just stayed looking around like that until Julie spoke again a moment later.

"I'm just kidding. Hurry and put it in me, my hungry pussy's waiting." Back in the moment he turned his focus back on his task. He slid his dick into her wanting pussy. It went in easily, yet still gripped him in a silky embrace and she moaned as he put his length into her all the way.

"Now fuck me good, baby brother," she said, grinning up at him, her face implying 'what are you gonna do about it' when she called him his hated name. "Seriously though Mark, enjoy my tight pussy."

Mark started fucking her as best he could. He pumped with a halting motion at first, while he got the hang of moving inside her. She moaned the entire time about how good he was and Mark felt sheepish because he was pretty sure she was just putting it on to be sexy for him. Laying it on a little thick, at that. But he didn't mind too much, because he was fucking for the first time and it was amazing. Besides, Julie was super hot and it was great to be able to have her be his first.

He grabbed Julie's tits and rubbed them as he pumped her. That made her moan louder and he started moving her hips in gentle counterpoint to his thrusting. "Like my titties there, Marky. Mmm, suck on 'em while you fuck me, if you can last."

At that, he collapsed down onto her and planted his mouth over her left nipple, suckling at it and moaning against her skin.

"Doesn't it feel so fucking good inside my pussy? Pretty soon you're going to shoot your load in there and it's going to make me scream for you. I love getting filled full of cum, you know. God, I can't wait for you to bust your nuts in my pussy, Marky."

"MMMM MMMM MMMM," she cooed while she caressed his ass cheeks. She saw the distant look creep into his face that signaled to her that he was so near to cumming. He was grunting with the build up of pleasure. She felt giddy with nticipation, waiting for him to explode his cum in her. She slapped his ass and yelled out to him, "cum now brother, fucking cum in me."

As he felt her hand stop rubbing his ass and a split second after, smack him a good one, he groaned in surprise and let loose with his first spurt of cum.

"YES YES MARKY, making you a man," Julie yelled.

"OMMHUH OMMHUH OMMHUH," Mark repeated incoherently as his ejaculation flooded into his 

sister. He kept pumping his cock into her until his orgasm was well over. It took him several moments to realize it, he was still riding the wave. He pulled his cock out of her and Julie just looked up at him smiling a wide, proud smile back at him.

"Way to go man, busted your cherry," she said and laughed.

"Oh god, that was so great."

"See now, what you've been missing? Gotta get out there and fuck some girls."

Mark just looked at her without saying anything. They both turned their heads toward Mark's open window as they heard their parents pulling the car into the driveway, They both jumped up and threw on their clothes in time to keep their secret safe.
