Undercover Sis

[Poprockz]

Lizzy was 18 and had just graduated high school. Since she wasn't sure which college she wanted to go to or what career to pursue, she was temporarily staying at her parent's house. The great thing about that was that her older brother was also staying there as well.

She had seen him as just a regular brother until a month or two ago when she had walked into his room without knocking. He had been tugging on his hard cock, and she had stood there wide-eyed in shock. Eventually he had yelled in embarrassment for her to close the door, but that moment had been enough. From then on, she took every opportunity she could get to see him naked or to touch him.

It seemed wrong at first, but she couldn't deny that she felt an ache in her pussy whenever she thought about him. He hadn't caught her yet (to her disappointment) but she had taken to going into his room and touching herself on his bed, imagining him watching her. Sometimes she would sneak outside and watch him from his window at night when she knew he might be tempted to jerk off. In daily life, her hand had brushed his crotch enough times for him to start noticing and being more wary around her, especially since she hugged him and rubbed her breasts against him any chance she could get.

The previous night, she had snuck into his room naked and slept with him. He was a pretty deep sleeper, so she had been able to rub her pussy on his knee enough to get herself to cum. She had then slept and woken up before him, scooting up against his torso and pulling his erect cock between her legs and pulling his strong arm around her.

Needless to say, he had woken up and gone into a panic, immediately expelling her from his room.


Lizzy sat on one of the lounge chairs in the front room while perusing through her phone, glancing up and smiling as her brother came in from the front door. She was wearing a white tube-top and a short black skirt. Her legs, covered with white knee-high socks were crossed, so he could see her pink lacy panties showing. She had long blonde hair and bright blue eyes.

"Finally you're home! Geeze! I feel like you've been gone forever!" She set her phone down and got up from her chair, scooting across the wood floor and hugging him tightly, pressing her large breasts against him. She went up and down on her tippy toes to rub her nipples against him while trying to make it seem like it could almost pass as her just being excited. Her dainty face looked up at him and she pouted, "What took you so long?"

Matt has just turned 20 last month. He was still living at home with his parents because he decided to take a break from school and just focus on a job for now until he knew what he wanted to go to school for. His little sister, Lizzy, also lived at home.

Things have been normal between them until she walked in on him masturbating a while ago. He had a very active libido so he did that often since he didn’t have a girlfriend. Ever since she walked in on him he felt like she was frequently trying to have sex with him. His theory was confirmed when he woke up one morning to her in bed with him naked. Her big juicy ass was pressed up against him and his morning wood was rubbing against her bare smooth pussy and his shaft was coated in her juices. Once he made Lizzy leave his room he realized his knee was covered in her juices too.

It was a shame she was his sister because she was so attractive too. Whenever she would hug him and press her breasts against him he would get so hard. He would frequently stroke his ten inch cock to relieve what his sister caused.

He was coming home from work when he opened the door and saw Lizzy witting there in a white tip and black skirt and he could see her pink panties. He closed the door and was almost instantly met with one of her hugs that pulled his face right into her breasts. “Great not even home for 30 seconds and my sister has my cock hard.” Matt thought to himself as he broke the hug off.

“I’ve been working Lizzy you know this.”

 

[Poprockz]

Lizzy shrugged, "You should just quit and stay home with me."

Another girl approached him and grinned, "Matt? Wow, you're looking great. I haven't seen you for a couple months and it feels like you just keep growing." The other girl was Stacie, one of Lizzy's best friends. Stacie was had long black hair and steely grey eyes.

[Orgasmicallyfun]

Matt was about to head right to his room but then Stacie appeared and started talking to him. Before he knew what was happening or even say his response the girls had him on the couch between them. Shots? Matt hasn’t eaten in a few hours so if he has a couple of shots they would hit him quick.

“Alright fine I’ll play your game.” Matt said trying not to notice his sister pressing her perky breasts against his side. He adjusted himself in the couch and adjusted his pants to try and hide the outline of his long thick cock.

 

[Poprockz]

They say and watched the movie, taking shots every now and then. Occasionally, Lizzy or Stacie would skip a shot when he wasn't paying attention. Soon, the girls were tipsy, and he was outright drunk.

"Ugh..." Lizzy rubbed her stomach. "You know, I don't feel super good. I'm going to go lay down for maybe an hour." She got up and made a show of looking sick as she went to her room, closing the door behind her. Lizzy leaned against the door, a devilish grin spreading across her face as she waited.

"Oh man, that's too bad." Stacie paused the movie and turned to him, putting her hand on his knee and rubbing it across his leg. "You know... I've always thought you were pretty hot. Did you... ever think that about me?" Stacie moved her to his inner thigh, continuing to rub her hand up and down across his pants.

"She's going to be gone for like an hour, or maybe more if she's really sick. Do you maybe want to have some fun in your room?" Her steely eyes smoldered at him lustfully.

 

[Orgasmicallyfun]

Soon it was time to take the first shot which Matt downed quickly feeling the burn in his throat. Then it was time for the second then the third. Soon Matt was certain he was drunk and just sat there as Lizzy got up complaining she didn’t feel good. “You never could hold your liquor.” Matt said before she disappeared.

Once they were alone Stacie’s hand was on his knee then soon his inner thigh and she grazed his impressive package. Matt couldn’t believe she was coming on to him. After nearly three months with no sex of course Matt agreed to move to his room. He stood up and after a stumble poured and downed another shot and then went to his room. Once in his room he went over to his bed and fell backwards into it.

 

[Poprockz]

Stacie grinned as she watched him fall back onto his bed. She watched him like a wolf about to devour a lost sheep. Crawling onto the bed, she unzipped his pants and pulled them down his legs, dropping them on the floor and admiring his enormous cock. He was already hard and ready for them.

She removed her shirt, revealing her magenta bra which cupped her voluptuous breasts. Her jeans were then wiggled down her smooth legs, revealing matching underwear. "Now Matt, I happen to like things a little kinkier. Can you keep up?" She crouched down and reached into her purse, taking out a blindfold and two pairs of leather handcuffs.

They were dangled in front of him for a moment before she crawled up the bed to his face, slowly tying the blindfold around his eyes. Her hand gripped his cock gently and started stroking. "Are you okay with the handcuffs, or should I stop?" Her hand teased him by pausing and almost lifting off of his shaft.

He couldn't see this, but Lizzy had silently entered the room. She had preemptively ditched all her clothes and was working the wetness between her legs with her fingers. She bit her lip as she watched her friend touch his cock.

 

[Orgasmicallyfun]

Matt watched as Stacie stripped down to the sexy magenta bra and panties. When she climbed on the bed and was working reach Matt reaches out and grabbed her big juicy ass and started to squeeze and run it. His fingers slipping deeper and rubbing her pantomime covered pussy feeling how wet she was.

She didn’t even wait for him to answer before she tied the blindfold around his eyes. He just nodded and softly said “Yes I’m okay with it!” He was so turned on right now he couldn’t wait to fuck Stacie.

 

[Poprockz]

"Mm. That's what I wanted to hear." Stacie let him squeeze her ass a bit more and shivered when he touched her pussy. She then gently grabbed one of his wrists and handcuffed it to the bedframe, doing so to the other as well.

Once that was done, she was given a nod from Lizzy to start riding him. Stacie let her fingers trace from his wrists, down his arms, down his smooth chest, and finally almost to his cock. Before she got there, she lifted her fingertips from him and grabbed the base of his cock. Her pussy was positioned above his groin and he could feel a bit of her juices drip onto his cock.

She rubbed his head against her slick pussy to get him lubed up, moving it back and forth across her clit a couple times as she let out a soft moan. When he was slick enough for her, she guided him to her entrance, slowly pushing down to try to get all of his cock inside her.

"God, your cock is so big, Matt. I'm regretting not doing this sooner." Stacie groaned with pleasure.

 

[Orgasmicallyfun]

Matt has never been handcuffed before so it was an exhilarating experience as he was cuffed to his bed. Then he felt her hands running down his arms and chest to his cock. He felt her hand grip his throbbing member and start rubbing against her very smooth wet pussy. Then it happened, she started to slide down his long thick pole.

“Oh fuckkkk!” Matt groaned out deeply feeling his entire length get swallowed up by Stacie’s tight warm pussy. “You feel so fucking good!” His fists clenched as she began to ride his huge cock.

[Poprockz]

"Your cock is going to make my pussy cum tonight, Matt. Your long, hard cock is going to be so deep inside me when you shoot your cum." she purred breathlessly, continuing to work her hips, her arms supporting her from behind as her powerful thighs lifted her up and down his shaft. Stacie started to roll her hips on top of him, purposefully tightening the walls of her pussy whenever she pulled almost off of him.

Suddenly she stopped. He could hear her wince. "Ah, it's just a leg cramp. Give me a sec." He felt her slide off his cock for a moment, walk and stretch for another moment, and then re-position herself. What he didn't know was that Lizzy had tapped her on the shoulder and given her a look, as they had agreed that he would cum inside her first.

Lizzy was actually the one who was sliding down his cock now. Her pussy was tighter than Stacie's and gripped him like she never wanted to let him go. For now, she was able to stifle her moans as she bit her lip and road him. It was so taboo, and yet she loved the feeling of being penetrated by his thick cock.

Stacie hovered nearby, ready to give him sound effects as if she were still riding. "All better now. Tell me, Matt. What do you want to do to this pussy?"

 

[Orgasmicallyfun]

Stacie was riding his cock better then any girl has in the past. When he heard her say her leg cramped up if he wasn’t tied down he would have flipped her over and fucked her so hard and deep. He laid there waiting for her to get back on top. He had no idea that it wasn’t Stacie that mounted his cock, he had no idea he was now balls deep inside of his little sister.

Matt groaned out so deeply and thrusted his hips of noticing how much tighter she felt he just though it was due to the different angle. He was loving Stacie’s dirty talk it turned him on so much. “I want to fuck this pussy all night long. I want to cum deep inside of it so many times.” He groaned. Stacie and Lizzy has no idea the stamina Matt has and he could go all night long in fact.

 

[Poprockz]

Lizzie couldn't help but let out a little whimper of pleasure as he thrusted and met her hips as she went up and down. Stacie smirked at what he was saying, finding it so delicious that he was talking about letting his semen burst into his little sister's pussy. "Oh yeah, I want all of your hot, sticky cum inside me. I want it to fill me up until I can't hold another drop. And then I want you to fuck my pretty pink throat." Stacie moaned, reveling in the sexual energy of the room. She leaned over and started to gently rub Lizzy's clit, causing another small whimper to come from her lips. Stacie licked her own lips and watched them intently, her other hand starting to rub her own clit.

"Tell me when you're about to cum, I want to know so I can cum with you!" Stacie whispered breathlessly.

 

[Orgasmicallyfun]

“Oh god!!!” Matt groaned as he continued thrusting up into what he thought was Stacie’s very tight little teen pussy. The combination of the pleasure from her tight pussy and the way she was talking to him brought him so close to the edge. “You want me to fill this tight little pussy baby? I’m so close to filling you up. You feel so fucking good baby!”

 

[Poprockz]

Lizzy couldn't hold back any longer and a loud, feminine moan escaped her as she roughly slammed her hips down upon him. She wanted him to cum inside of her so badly, this had been what she had wanted for months.

"Please Matt, please cum for me! I need it!" Stacie moaned, her fingers speeding up on both of the girl's clits.

Just as he was about to cum, Stacie removed his blindfold to reveal his little sister helplessly rocking her hips against his cock. Her large breasts jiggled and bounced with the force of their thrusts. Her face was contorted with pleasure, her glossy pink lips slightly parted as she panted and moaned. It was at that moment that he could feel himself start to cum.

 

[Orgasmicallyfun]

“Fuck I’m going to cum!” Matt groaned and seconds later the blindfold was ripped off and he couldn’t believe what he saw. His little sister was the one bouncing up and down his cock. He was fucking his little sister and her pussy felt so fucking good. As she came her pussy grew even tighter around him sending him over the edge.

“Lizzy?! No get off I’m going to cum!!”” Matt groaned deeply and struggle but was stuck beneath his little sister helplessly cumming so deep inside of her. He didn’t know what caused it but he shot off the biggest load he ever shot off before. Cumming for nearly a fully minute as Lizzy kept moving up and down his long thick cock.

[Poprockz]

"No, Matt! I need it so bad! I need my big brother's thick load!" Her small body shuddered as she felt him fill her up with his hot semen. It was such a large load that she could feel it drip out of her pussy and down his cock. She came a second time on top of him as she felt so full.

When she finally grinded to a halt, she got off of his cock and knelt on her hands and knees between his legs. "I made such a mess on your bed. I'm sorry, I'll go ahead and clean it up." She leaned forward and licked some of the cum and her own juices off of his cock, running her tongue up and down his length. She paused for a moment to look up into his eyes as she licked him clean, trying to get him hard once more so that she could feel him burst inside her again.

Stacie was done just watching. She knelt above his face, facing Lizzy and lowered her dripping folds to his lips. "Now that you both have cum, don't you think it's only right that you pleasure me with that strong mouth of yours?" He could feel the heat radiating off her aroused pussy.

 

[Orgasmicallyfun]

Matt laid there in shock having just cum such a big load inside of his little sister. “I can’t believe that just happened.” He said softly while Lizzy was now between his legs licking his cock clean. It was useless to struggle since he was cuffed to the bed.

The Stacie moved to hover over Matt’s face. “You tricked me!” He said right before her pussy landed on his mouth. He was still very horny and started licking her almost instantly. Lapping his tongue along her dripping wet pussy lips. His cock growing to life in his sister’s hand and against her wet tongue.

 

[Poprockz]

Stacie chuckled and sighed softly as he started to pleasure her. "Yes, we tricked you. But it felt so good to fill your little sister's barely-legal pussy up didn't it? You made her cum on top of you, even though you're handcuffed to the bed. Why resist when you've already done the unthinkable?" Stacie moaned as he hungrily lapped at her pussy.

Lizzy continued to lick his cock until he was clean and erect. From her position on her hands and knees, she could feel his cum slowly dripping down her thighs and she loved it- It made her feel dirty.

His cock was now rigid enough for Lizzy to ride him once more, and she did so without delay, letting him nestle his cock inside her womanhood once more. She was happy that she didn't have to stay quiet now, since his cock seemed to want her to make lewd noises. "Matt. I'm so happy. It feels so good!" she huffed as she rolled her hips on top of him.

Stacie leaned over and put her hand on the back of Lizzy's neck, bringer her in close for a kiss as they moaned on top of him. Her tongue entered Lizzy's mouth and played with her tongue, twisting and rubbing around it.

 

[Orgasmicallyfun]

Matt was still so drunk he was just focusing on how good it felt having his sister licking his long thick cock while Stacie rose his face. Her juicy ass cheeks covering his entire face while he ate her pussy out. Eating pussy was one of his favorite things to do and he was very good at it. The tip of his tongue flicking against her tiny clit and he’d alternate that by sucking on it lovingly.

Then he was mounted again by his little sister. He couldn’t help but groan out against Stacie when Lizzy slid down his huge cock. Her slick inner walls gripping him tightly and she was so much more wet and warm from all the cum inside of her. Being so drunk he wasn’t thinking so much about how wrong it was, but instead how incredible her tight little pussy felt.

The three of them could hear the very lewd wet sounds coming from Lizzy’s cum filled pussy as she moved on her brother’s long rigid pole. Matt even started to buck his hips meeting her movements as the siblings found a perfect rhythm.

 

[Poprockz]

Stacie moaned as she felt him navigate his tongue around her clit. When he would suck, he could feel her squirm on top of him, the pleasure being too much for her to stay still. She broke the kiss with Lizzy and rested her hands on his chest, rubbing his soft skin tenderly. "It seems like you like eating my juicy pussy, Matt. If you keep that up, I'll have no choice but to cum on your face."

Lizzy was surprised that he was actually meeting her thrusts with his own. This had turned out better than she had thought possible.She loved the soft squelching sound that came from him pumping his thick rod into her swollen pussy. Feminine whimpers of pleasure sounded from her as she pleasured him. "I can't wait to feel your cum again, Matt. I bet it will feel even better the second time."

 

[Orgasmicallyfun]

Matt was so drunk he was trying not to think of it being Lizzy on his cock, but some random teen who he was fucking balls deep in her tight young pussy. This was his biggest fantasy to have a threesome and he wanted to enjoy it even if it meant fucking his little sister again.

Matt was in love with Stacie’s pussy and how she tasted. He couldn’t stop licking her dripping wet cunt that had his face covered in her juices. When she squirmed on his face he enjoyed the feeling of the soft smooth flesh of her ass and thighs rubbing against his face and the side of his face.

This was the best sexual experience of his life even though it involves his sister. He started bucking his hips even harder reaching so deep inside of Lizzy’s cum filled pussy. He was getting close to blasting another load inside of her. Tonight his sister and Stacie would find out how much of a sexual animal Matt is.

 

[Poprockz]

Stacie gasped as he continued to slide his tongue along her sopping wet cunt. Her legs began to tremble as she felt like she was about to go over the edge. "I'm going to cum, Matt. Your perverted tongue is going to make be squirt!" Stacie breathlessly whimpered.

"Yes! God I've never felt something so deep!" Lizzy cried out as she was slammed hard. She fondled her own breasts and pinched her nipples, her eyes squeezed shut so that she could better savor the feeling of being impaled on his shaft. Like Stacie, she was getting close to cumming again as well. He could hear it in their desperate moans that they going crazy over his tongue and cock.

 

[Orgasmicallyfun]

“Cum for me!” Matt moaned out against Stacie’s pussy then went back to licking her sweet cunt. He loved having two girls so crazy for his tongue and cock. He felt himself getting near the edge again. If he was sober he would have been fighting this but now he wanted to cum deep inside the tight pussy that was riding him, even if it belonged to his sister. “I’m going to cum!” He groaned out then went back to devouring Stacie.

 

[Poprockz]

Stacie shuddered and twitched as she suddenly orgasmed, squirting from all the stimulation of his agile tongue. She grinded her pussy against his mouth, trying to get every last wave of pleasure that he could offer. "So fucking good! Shit!" she purred.

Lizzy bounced as energetically as she could, so turned on by him calling out to her and by the thought of him emptying his balls deep within her. Her face was desperate, her blond hair swaying back and forth. "Matt!" she groaned as she came, squeezing his cock like a python while still humping him with reckless abandon. She loved squeezing him and feeling like his cock was fighting to pump in and out of her.
