Undercover Sis

[Orgasmicallyfun]

“Oh so you own your brother’s cock? Loaning me out to Stacie from time to time?” Matt asked with a smirk loving how naughty this was. Lizzy’s pussy was so wet from her own juices and his pre cum that was oozing out of his cock like a river. While squeezing her breast Matt ran his tongue from her neck to her nipple and he started to run his tongue in circles around her nipple then he started to suck on her nipple while fucking her so deep. Her tight cunt gripping his cock so tightly.

 

[Poprockz]

"Well you're MY brother, so naturally I have first dibs." Lizzy responded in a matter-of-fact way, whimpering as he started to suck on her nipple and play with it. Her nipples were so sensitive right now, maybe because the fact that it was his mouth on her skin made her go a little crazy.

She contracted the walls of her pussy, trying to test him to see if she could actually hold him prisoner inside her fleshy prison. He started to have a little bit of difficulty moving around inside her, but she could tell by his expression that he loved every second of it. "Maybe I'll just keep you in my cage like a bird, and I'll make you sing for me to release you."

 

[Orgasmicallyfun]

Matt releases Lizzy’s nipple from his mouth when she squeezed her pussy so tight around his cock that he could barely move in and out of her. He was amazed at how tight she could get and how amazing it felt. “Oh god that’s so tight! It feels so good I don’t think I’d ever ask to be released from this cage.” He said with a smirk before leaning back down to resume sucking on her nipples. This time he took more then her nipple on his mouth taking a mouthful of her breast and swirling his tongue around her nipple.

 

[Poprockz]

His hot mouth and wet tongue felt made her nipple tingle with pleasure. She moaned and submitted her body to the barrage of lust he was directing at her. The leg that was still in contact with the floor trembled as the toes on her other foot curled. His girthy member was filling her up so nicely, as if it was made for her. She released the pressure a bit so that he could pound her harder. She was getting very close to cumming

"My pussy is so close..." she groaned, little feminine whimpers coming from her each time his cock would slam back inside her.

 

[Orgasmicallyfun]

“I’m close too!” Matt groaned with his sister as he continued pumping his long meaty cock in and out of his sister’s tight young pussy. “I can’t believe I’m fucking my little sister and that it feels so fucking good!” He added as he picked up the pace with his thrusting. “I’m gonna cum!!”

[Poprockz]

"Yes! fill up your naughty little sister's pussy!" she cried as her pussy spasmed and contracted from the overwhelming orgasm that rocked her. Her body would have slumped to the floor if he hadn't been holding her leg and pressing her against the wall.

He pumped his cock inside her once more and held it there; she felt his cock twitch and let loose a torrent of cum inside her, shooting bursts of his milky cream deep inside her slim teen body. The hot semen dripped down her legs from around his cock as they stood there, panting and looking each other in the eyes, both of them so turned on by the other. It didn't seem like he was going soft yet, either.

 

[Orgasmicallyfun]

“Fuck yes! I’m cumming inside of you sis!!” Matt groaned deeply as he let loose one of his famous monster creamy warm loads inside of Lizzy. The cum overflowing and running down her leg onto the shower floor. Matt pumped his cum so deep inside of his little sister. The first load he shot inside of her while sober. Something so forbidden and naughty seemed to unlock something deep inside of Matt. He was addicted to fucking and cumming inside of Lizzy.

They looked into each other’s eyes, both of them wanting more but not needing to say it. I’m one swift motion Matt hooked his arms under Lizzy’s legs and pinned her against the shower wall. His cock didn’t soften one bit and he was going to use that to his advantage and keep fucking the tightest pussy he ever felt.

 

[Poprockz]

She gasped as he picked her up off the floor, his cock still buried inside her cum-covered cunt. One of her hands grabbed his shoulder and the other wrapped around his neck to steady herself. It was such a vulnerable feeling being held up in the air in his arms while being pressed against the wall. She felt safe with him, though, and knew he wouldn't drop her. By holding each of her legs, he was able to spread her wider and get a better angle for fucking her deepest recesses.

Lizzy had only ever fucked one other guy, and he didn't compare to Matt at all. She didn't think the other guy had even bent able to make her cum like her brother could. She wished she could have given her brother her virginity, but was glad at least that she was able to change his mind and have him give in to his desire for her.

 

[Orgasmicallyfun]

“So fucking tight!” Matt said softly his lips so close to Lizzy’s. He pushed so deep inside of her causing so much cum to ooze out around his cock and run down his legs. They weren’t being hit by the water right now so the cum that was oozing out was coating their bodies and stretching between the two siblings turning them into hot sticky messes.

 

[Poprockz]

Lizzy felt so dirty being covered in his cum. She loved the sticky feeling and sound as their cum-covered bodies slapped together with dirty squishing noises. It made her feel like she was a receptacle for his sperm, a whore that he could use for all of his perverted desires.

"I love having your cum all over me. It makes me feel like such a slut!" She exclaimed as she felt some of his seed run down out of her pussy and back to her asshole, teasing her. "I don't mind being your slut, though, Matt."

 

[Orgasmicallyfun]

“Yeah you like being my little slut. Wanting your brother’s cock and cum all to herself?” Lizzy’s dirty talk was inspiring Matt to become vocal towards his sister as well. “How much cum do you think I can fit inside this tight little pussy?” Matt added as he continued fucking her, the lewd wet squishing and slapping sounds of their fucking were louder then the shower now.

 

[Poprockz]

"I think you can fit all of your cum inside me. If my pussy can't take it, I would let you fuck my tight little ass as long as you were gentle." Lizzy had never done anal before, but something about her brother made her willing to give up all of herself for his sexual pleasure. She didn't doubt that his cock would take some getting used to the first couple times, but that she would be able to take it for him.

Her legs bucked a little from the force of his gargantuan cock hitting her deep erogenous zones. He was being so rough with her pussy and it only added to her excitement. The lewd sounds they were making was music to her ears.

 

[Orgasmicallyfun]

“Well we are going to find out because I am going to cum again!” Matt groaned deeply seconds away from shooting another load onto his sister’s incestuous pussy. Lizzy’s insanely tight, wet and warm pussy diminished his stamina that he showcases with Stacie’s pussy earlier. Matt shot another big load into Lizzy’s pussy causing some cum to spurt out and splash onto Matt’s own body making their fuck even wet and stickier.

The pressure from Lizzy’s tight tight pussy kept Matt rock solid inside of her. As long as he was hard he intended to keep fucking his little sister.

 

[Poprockz]

Lizzy was sensitive from having already cum previously, so this next load of cum pushed her over the edge once more. "Matt!" she cried out his name as she felt the wonderful sensations of her climax travel to her very toes. She panted as she tried to recover, but wasn't given the chance as he assailed her once more with his erect pole.

"Are you making up for lost time, Matt? For all the months since I've turned 18?" She didn't wait for a reply as she leaned forward and enveloped his mouth, sucking and licking with reckless abandon, drunk off the feeling of his lust.

 

[Orgasmicallyfun]

The wet lewd sound only becoming louder as the amount of cum in and around her pussy doubled. “Making up for all the times you got my cock hard and o should have fucked you.” Matt said before his mouth was enveloped in a wet steamy kiss from his sister. Their tongues and lips not being able to get enough of each other.

 

[Poprockz]

"Mmm!" She moaned against him, trying to rock her hips against him as will to help him fuck her. Her mouth was so hungry for him, it felt like she would never be satiated no matter how much she tasted and plunged her tongue between his lips. Saliva ran down her chin and dripped onto her chest as they sloppily made out.

Lizzy shifted in his grasp and moved so that her legs were around his hips, locked together at the ankles behind him. Her strong legs squeezed him as he thrusted. Her eyes rolled back from the intensity of his love-making.

 

[Orgasmicallyfun]

The sloppy spit swapping make out session between the two siblings was so fucking hot and turned Matt on so much. Their saliva dribbling down both of their chins and onto Lizzy’s bouncing tits. As she locked her legs around his back Matt changed his rhythm to slow powerful thrusts. Both of them feeling her warm and wet pussy gripping his long thick cock beautifully. The siblings feeling ever ridge and detail of each other.

 

[Poprockz]

Lizzy shuddered as she felt his bulbous head slowly massaging the inside of her pussy. She took the opportunity to squeeze him with her strong vaginal muscles again, but only as he would try to withdraw himself from her.

Drawing back for air, she kissed his forehead affectionately and spoke, "You know, sometimes I would touch myself in your bed. I was hoping you would catch me, but you never did. Did you ever think of me?"

 

[Orgasmicallyfun]

Matt was amazed again by how strongly her pussy gripped his cock. Anytime he pulled out he would come to a stop from her strong muscles gripping his throbbing cock. Then he would just slide back deep inside of her when her muscles relaxed. He listened as Lizzy began to confess naughty things to him.

“I have thought about you...” Matt confesses to his sister. “..for a couple years now. Ever since I walked in on you changing a couple years ago the image of your naked body was burned in my mind.”

 

[Poprockz]

She looked at him, surprised. "I remember that day. You said your stomach didn't feel good and so you stayed in your room for the rest of the day. Were you... touching yourself?" Lizzy was shocked that he had been watching her for far longer than she had been lusting for him. Ever since that day, he never seemed to bring his friends over to the house either.

"You stopped bringing your friends by for sleepovers too. Why was that?" She looked at him curiously before licking his neck in one long lick.

 

[Orgasmicallyfun]

“Yes... yes I did.” Matt confesses more secrets to his sister while keeping his movements slow and passionate. “I came so much that day while thinking about my naked little sister.” Back then he felt so guilty thinking about his young sister the way he did, and now that he was fucking her like he wanted to back in the day he had no feeling of guilt.

“I stopped inviting them over because I didn’t want them to hook up with you. I wanted my sister..” he said groaning softly as she licked his neck. She was driving him wild with lust and he felt like he could fuck Lizzy all day.

 

[Poprockz]

"Wow, so you've had the hots for me for a while..." Lizzy purred into his neck, sucking on it and letting her tongue run over his skin some more. She was extremely flattered that he had been lusting after her for so long. The restraint he must have had must have been enormous. She had a small orgasm at that point, squeezing him with her legs for support as she moaned.

Panting she spoke again, 'You know, your friend Devin once tried to get in my pants while you were sleeping. I never told you because I didn't want to ruin your friendship with him and he only tried the once." She looked away from him for a moment, remembering.

 

[Orgasmicallyfun]

Matt felt Lizzy’s pussy pulse around his manhood when she had a small orgasm. He was addicted to the amazing pleasure her pussy brought him and couldn’t get enough of it. “Devin wouldn’t be able to fuck toy like your brother can.” He said as he started to speed his thrusts up and moments later he was on the verge of giving his sister a third load of cum. “He wouldn’t be able to take care of you like this.” He pushed so deep inside of her and released a third load of cum inside of his sister.

 

[Poprockz]

"No he wouldn't. I only want my big brother's big cock!" she groaned in response as he exploded inside her again. She felt like he had probably given her more cum than any woman could fit inside of themselves. She wondered if it was possible for some of it to have been pushed into her womb, not that she minded. It was such a good feeling to be filled up with hot liquid that she knew came from her brother's love for her sexy body.

Lizzy came again from that train of thought and from being so full. He had made her cum so many times this morning, she was almost delirious from having climaxed so many times.

 

[Orgasmicallyfun]

Matt’s legs were beginning to grow weak from shooting off so many big loads of cum. He didn’t want to pull out of Lizzy’s pussy so he went over to the little bench in the corner of the shower and sat down keeping his cock inside of his sister and her on his lap. “You can have this cock whenever you want sis.” Matt said drunk on lust for this newfound incestuous addiction. His lips found hers and they started making out again he kissed her hungrily not able to get enough of her kisses.
