Undercover Sis

[Orgasmicallyfun]

Matt’s hands moved down to his sister’s hips and he pulled her downward so that she began to slide her very tight young wet pussy down his length. Slowly one inch by another was swallowed by her very tight cunt. Soon all ten inches were deep inside of Lizzy with people a few feet from them this was definitely the naughtiest thing Matt has ever done. “Fuck you are so so tight!” He whispered in her ear.

Even though there was a blanket covering her, it got her hot and heavy to sit on his lap with her legs splayed outward like this. She imagined what it would look like if the blanket were removed; her cute little teen body skewered upon his throbbing cock. They would be able to see how utterly full he made her, barely fitting his length in her swollen pussy. Her pussy and her love for her brother would be on full display.

Her body shuddered from a small orgasm at the thought of it and the feeling so full.

 

[Orgasmicallyfun]

Matt felt his sister’s pussy tighten when she had her small orgasm. He loves how incredible tight she got around his cock squeezing his incestuous cock so perfectly. He rested his head back against the seat trying to hold in a deep groan as she already came on his cock. “That feels so fucking good!” He whispered in a very soft groan.

 

[Poprockz]

"Yes..." she breathed in response. She started to move on top of him quietly. Her movements were fairly slow, but deep. The theater wasn't silent, so they could make a little noise, but she didn't want to speed up until there was a louder scene on screen. Otherwise, people would hear the sloshing of her pussy being possibly impregnated by her brother. His sister had considered the possibility that even on birth control, there was still a possibility of pregnancy, but she didn't care. She would be more than happy to bear his child for him.

In fact, the very slight risk of pregnancy turned her on as well. Lizzy rolled her hips a bit, moving his cock around inside her dirty, womanly tunnel.

 

[Orgasmicallyfun]

The way Lizzy moved her hips on top of him had Matt already about to cum. Between the exciting thrill of being caught and his sister’s very tight pussy gripping his cock Matt was in heaven. His hands gripping her hips as she moved on his giant pole. He felt her big teen ass pressing against his body each time she came down his throbbing cock. “I love your tight pussy sis!” He groaned softly.

 

[Poprockz]

"Show me how much you love it." She stopped moving on top of him, waiting for him to take her words in and see that she was inviting him to thrust into her. His sister wanted him to show her how eager he was to cum inside her, how much passion he could put behind his thrusts. The movie was starting to get louder as an action scene started, everyone's eyes glued to the screen.

 

[Orgasmicallyfun]

Once the sound started to pick up with the action on the screen Matt showed Lizzy just how much he loved her pussy. He leaned back into the seat and stiffened his legs and began to thrust up into her young tight hole. Matt could heat the wet squelching sound as he thrusts in and out of her pussy. His hands sliding up under her shirt and grabbing her big tits squeezing them firmly as he released a soft groan and cane so hard in Lizzy’s pussy. His came with so much force that her pussy filled up and his cum shot out onto he floor and seat back in front of them.

 

[Poprockz]

"Just like that!" she whispered to him, reveling in the feeling of his lust-filled thrusts. His hands sliding under her shirt made her shiver and she bit her lip when she felt him start to squeeze her mounds. His hands were so talented, kneading and squeezing each of them lovingly. When she felt him tense up, she knew he was about to shoot. She waited and lifted a hand to clamp down on her mouth as she felt his fluids spilling into her unprotected womb, shuddering as she also came from the feeling of his semen.

"There's so much evidence here to to link you to the crime when they come to try to find the miscreant responsible for murdering my pussy. " she whispered playfully, leaning back and kissing him on the forehead.

 

[Orgasmicallyfun]

Matt smirked when she said that last line and it made his cock twitch inside of her sending another ribbon of white hot cum into her womb. When she kissed his forehead a hand slipped out from her shirt and landed on her neck and he kissed her very deeply. “It’s still an active crime scene though.” Matt said as he took a quick look around and then quickly and quietly moved them and bent Lizzy over the arm rests. His long seemingly endless cock still inside of his sister. His hands now on her hips holding her skirt above her ass and he started to fuck her again.

 

[Poprockz]

She was now bent at the waist over the arm rest, her ass slightly in the air for him to pound mercilessly. Lizzy felt a little bit bad for whoever had to clean the theater after this, but not enough to let it bother her. Some of his cum dripped down her thighs as it spilled out from him continuing to fuck her. Her back arched a bit to give him a good angle for hitting some of her better spots.

"Would they say it was a crime of passion?" she asked, returning her hand to her mouth to stifle her moans. Her body jerked forward from the force of his body, her breasts swaying back and forth.

 

[Orgasmicallyfun]

Matt grabbed a handful of Lizzy’s hair and pulled her body backwards. “A crime of great passion.” Matt said as he kept lovingly fucking his little sister. Globe of cum and juices falling down onto the seats and their thighs. Thankfully the movie was still pretty loud or else people would definitely hear the wet squishing sounds of his huge cock thrusting in and out of Lizzy’s tiny creampied pussy.

 

[Poprockz]

She wanted to moan out loud so badly, but kept herself from doing so. The ridges of his bulbous head felt so good running across the walls of her pussy. Lizzy loved when he pulled her hair, and let him arch her back further. Her well-toned thighs were spread for him, her brother, as he screwed her without a care in the world in the dark theater.

 

[Orgasmicallyfun]

One hand was still in her hair and his other hand was holding her skirt up and resting on her lower stomach right above her pussy. “This is so fucking hot Lizzy!” Matt groaned in her ear. After a few more minutes which involved some heavy making out Matt warned his sister that he was about to cum again.

 

[Poprockz]

"More!" she begged softly as she felt him start to tense again. Her hips pushed back on him and she reached back, letting her chest and breasts be pushed into one of the seats. Her hands reached back to her ass and spread her cheeks so he had a better view of his cock burrowing into her pussy. Her nipples rubbed against the plush fabric of the seat, making her tingle.

 

[Orgasmicallyfun]

When Lizzy spread her ass and the light from the movie hit her ass he saw the amazing sight of his huge cock stuffed deep into her tight pink pussy with globe of white gooey cum oozing out around him. His hands replaced hers spreading her ass while he slowly moved his hips. His cum oozing out all over her pussy and her ass making both of them all wet and slimy and warm.

 

[Poprockz]

She closed her eyes and listened to the squelching of his cock in her pussy. It sounded so squishy and wet, and she loved hearing the sound of his cum being slowly pounded out of her pussy to make room for a new load. She imagined the look on his face as he watched his cock impale her. It was likely that from his point of view she looked like a gooey iced cinnamon role, the icing running down the side.

 

[Orgasmicallyfun]

Matt couldn’t believe they were actually fucking in a movie theater. Lizzy was so naughty to get this started, but it made Matt even more attracted to his sister seeing this naughty side of her. Especially the side of her bent over the armrests of the chairs with his very long thick cock sliding in and out of her and his cum all over her making her look like a cinnamon roll covered with excess icing. Matt briefly picked up his thrusts even faster and harder while there was an action scene on the movie and fucked Lizzy deep and hard squeezing her ass with his hands while he started to cum again inside of her heavenly teen pussy.

 

[Poprockz]

“Yes! Please! Fill my womb with your cum! I don’t care if I get pregnant...” Litzy moaned softly, cum dripping down her legs as she panted and tried to catch her breath. Miraculously no one had seen or heard them. Even as they recovered from their passionate whirlwind of sexual desire. Lizzy looked back at him lovingly, saying words she had spoken before, “I love you.” Though they had a different meaning now.

 

[Orgasmicallyfun]

Matt’s hips eventually stopped moving and he held his cock deep inside of his little sister. This definitely took the lead as the naughtiest things Matt had ever done. Lizzy looked back at him and told him she loved him. Matt smiles and pulled his sister back for a passionate kiss. “I love you too.” He said after the kiss and looked into her eyes. He slipped his cock from inside of her and saw the globes of cum glistening in the movie light as they fell onto the chairs and floor beneath them.

 

[Poprockz]

The rest of the movie was uneventful for the most part. She had taken some wipes out of her purse to clean herself off with before moving them over a couple seats to leave the large dripping mess of cum. She had tenderly cleaned him off as well, before fastening his pants and sitting with her head leaning on his shoulder. The movie was soon over and they headed home, both still flooded with endorphins from cumming so many times.

 

[Orgasmicallyfun]

After they cleaned off and got comfortable the movie finished shortly after since they spent most of the movie fucking. They returned home and went inside, once inside he kissed her deeply, one hand on her neck and the other squeezing her ass. “Why don’t we go change into comfortable clothes and hang out and watch a movie together?” He said still squeezing her big butt.

 

[Poprockz]

"Sure, I would like that." She smiled up at him. "Just let me use the restroom real quick." Lizzy walked into the restroom and shut the door, turning the lock. She took out a box from the drawer and opened what was inside, sitting on the toilet and relieving herself. Once done, she set it on a piece of toilet paper on the counter and washed her hands, pacing back and forth.

It was time. She lifted the pregnancy test to see if it would confirm what she hoped. Yes. The test was positive: she would now have the privilege of bearing her brother's child. She grinned, she couldn't wait to tell him the good news.
