Undercover Sis

"Why are you going so slow?" Stacie asked, impatiently. She tried to push back against him harder, but he was gripping her ass tight enough to slow her down. "You're so mean, Matt. You know you want to fuck me till I scream your name. MmmmMatt." Her pussy had a burning need to be slammed with force, and she was being made to wait for him. The only consolation was that his cock still felt really good and she loved that he was tempted to stick a finger in her ass.

After a while she was on the verge of asking him to fuck her harder when he started doing so himself, quite suddenly. "God, yes. Fuck me like a dirty whore." she groaned with desire. "I want to drip cum onto your sister's pussy." She tried to help by pushing back and bouncing her ass off his hips. The sexy sloshing noise coupled with the clap of her ass drove her wild, making her moan loudly with each thrust.

Matt increased the speed of his thrusts and started fucking Stacie even harder “You like when I fuck this pussy nice and hard don’t you?” Matt slapped Stacie’s ass and then he leaned down and grabbed her hair pulling her back slightly. “I’m going to fuck this tight pussy so hard you’ll have trouble walking tomorrow.”

Matt then ran his tongue up along her neck and nibbles on her ear. Then he turned her head and the two engaged in a very sexy open mouth kiss. Their tongues rubbing and twisting together. A few drops of their saliva dropped down onto Lizzy who was close enough to join their erotic kiss.

 

[Poprockz]

"Yes, I love it! God Yes! Fuck me so hard I have to crawl home with my ass in the air!" She growled in response, gasping and squeezing when he slapped her. Grabbing her hair was a good move as she cried out in delight and licked her lips before continuing to push back against his throbbing cock. She felt so much pleasure by the way his huge cock shoved her insides to the side as it forced its way as deep as it wanted.

Stacie closed her eyes as she kissed him back, not caring whether their lips were connected. All she needed was to feel his tongue on hers and to taste his sweet saliva.

Lizzy leaned forward and opened her mouth, catching a few strands of their mixed saliva before joining into the fun. It was like she was in a three-way battle for his tongue as both of the girls tried to bring him into their own mouth. Their tongues slipping and rubbing against his.

 

[Orgasmicallyfun]

Every time Matt thrusted deep inside of Stacie her big juicy ass rippled after their bodies met. His cock was coated with her juices she was so wet the sound coming from her tight pussy was so kinky and erotic. Stacie was going to see just how much sexual stamina Matt had. He was not slowing down at all. His body began to sweat but his hips moved so fast and hard.

When Lizzy joined the kiss and the two teens seemed to duel over his tongue Matt nearly came right there from how sexy that was. Both girls could taste each other and the liquor Matt drank earlier off of his tongue. So much saliva was being swapped between the three. Lizzy sucked on his tongue briefly then Stacie managed to pull his tongue away and suck on it then the three of their tongues went back to the erotic make out session.

 

[Poprockz]

Stacie had expected him to have cum by now, but she gladly accepted the continual assault of his cock on her own sanity. She could feel his balls slapping against her clit as he forcefully sledgehammered the ripe fruit of her loins. Juice splattered and sprayed a little from how hard he was going and how wet he had made her. Flecks of pussy fluids flicked onto Lizzy’s legs.

Stacie reached underneath and rubbed Lizzy’s clit, throwing her off-guard and causing her to withdraw for a moment. This left his tongue open to her. Her eyes looked at him playfully, seemingly to say that she didn’t mind using underhanded methods to get what she wanted. Lizzy recovered and pinched Stacie’s nipple hard, causing her to throw her head back in a loud moan. Lizzy then stole him back, sucking his soft tongue back into her mouth to play.

 

[Orgasmicallyfun]

Having the two teens dueling over his tongue was so hot and the fact that one of those teens was his sister was even more erotic. For some reason her forbidden kisses turned him on so much. When Lizzy started sucking on his tongue again Matt came so hard inside of Stacie. There was so much fun it oozes out and leaked down onto Lizzy. Matt pulled out like he was done but he just wanted to watch his cum leak from her cunt.

He then guided his still hard cock back into Stacie and pulled her hair slipped so deep inside of her. Pushing his cum all the way to her womb. “I’m not done with this pussy yet!”

He groaned before starting to roughly fuck Stacie again.

 

[Poprockz]

Stacie moaned and climaxed as he filled her to the brim. She then relaxed, expecting for him to either be done or to work his cock back up for Lizzy. Instead, she was startled when he shoved back into her sticky, used pussy. “How are you still hard?!” she gasped in amazement, being forced to lean down again with her head pulled back- all as she tried to withstand the force of his powerful hips.

Lizzy squirmed as she felt his hot cum drop directly onto her clit, coating her in his cream. She noticed at that point that he had literally gotten cum all over the bed. There was no doubt that his sheets would have to be cleaned thoroughly after all of this. His cum was also all over their thighs, legs, and pussies. Some even got other places from them rearranging positions on the bed. She was in awe of how much he had actually cum this session.

 

[Orgasmicallyfun]

Matt smirked when Stacie asked he was still hard. He was amazed himself, usually he’d go soft and need to recover, but having these two girls craving his cum like this kept him rock hard. One of those girls being his sister only added to the erotic nature of things.

His hand was holding her hair and pulled her head back he leaned down and started to suck on her neck. He saw Lizzy looking around the room and soon their eyes met. He then brought his other hand to her neck and pulled her in for a steamy erotic sibling kiss while he drilled her best friend. Globs of cum frequently falling down and landing on her pussy and stomach.

 

[Poprockz]

As slutty as Stacie was, she had never been fucked so completely. She came again as he sucked on her neck, squirting her juices onto Lizzy below. Her body was so sensitive from having cum so many times, she was in bliss. "My mind is going blank..." Stacie whimpered helplessly.

Lizzy locked eyes with him as he pulled her to him. She needed one hand to support herself while sitting up, but the other she reached down to rub her clit, the semen making her fingers slide easily over it. She gladly let her mouth be taken over by him, moaning into his mouth as her tongue found his and started rubbing alongside it. She pulled away a bit and sucked on his lip for a moment, gently nipping it and pulling it with her teeth before letting it go. Her head leaned to his ear and she whispered, "You're the best brother a sister could ask for." After speaking those words, she kissed his mouth with renewed vigor, trying to show him how much she had wanted him this past couple months.

 

[Orgasmicallyfun]

The way Liszt returned Matt’s kiss was the sexiest kiss Matt ever shared with a girl before. So much passion behind it. The fact that she was his sister only fueled the steamy kiss. Matt smiles when she told him he was the best brother a sister could ever ask for. “That makes me happy.”

This was the wettest sex Matt has ever had before. There was still so much fun inside of her that was coating his cock and covering their bodies and her juices were squirting out onto him and his sister below. He was so close to pumping yet another load into Stacie’s teen pussy. “You want me to cum in this pussy again?” Matt asked softly in Stacie’s ear

[Poprockz]

"Matt!" as he pulled away from her, Lizzy came from vigorously rubbing her clit. She imagined that it was his hand that was playing her instrument as he told her that he made him happy. She came so hard that she was forced to lay back down under Stacie, the pleasure rippling through her body as more fluids dripped onto her skin.

"Yes Matt, cum in my filthy pussy!" Stacie begged, her body quivering. Her body was also sweating a little from the exercise he had put her through that night. She grabbed Lizzy's hands one by one and had her squeeze her breasts as she hoped he was getting close. Her ass rippled like a pond with each time he slammed his huge cock inside. The room was filled with the sounds of hard breathing, moans, and the slapping of skin-on-skin.

 

[Orgasmicallyfun]

“Alright get ready baby!” Matt groaned still holding onto her hair. The other hand he brought back up and slapped her ass. Then he held onto her ass getting a handful of her asscheek and sttted to fuck her as hard and fast as his body would let him. The loud sounds of their bodies meeting were almost non stop he was fucking her so fast.

Then he released another massive kid of thick creamy cum into Stacie’s pussy. His body very sweaty now after such a vigorous work out. He slowed his hips while her tight phase milked every last drop of cum from him. He then pulled out and watched the river of white flow down onto his sister. He collapsed onto the bed right next to Lizzy breathing heavily after that intense work out.

 

[Poprockz]

Stacie wailed with pleasure. She had no shame in crying out as he doubled-down on her. Had their parents actually been in the house at the time, they surely would have heard her. As it was, they were lucky that the parents had taken off earlier that Friday afternoon and would be gone for the weekend.

After he released his load into her, she knelt there for a few moments, trying to recover from the vigorous pounding she had endured while he slowly came to a halt and removed himself. She could feel his milky seed spilling out of her pussy, and he had another small orgasm. When she was at least in her right mind, she collapsed onto the bed as well, right next to Lizzy.

They all panted in the bed, looking up at the ceiling as they lay in a bed of cum. Stacie turned off the lamp in the bedroom, throwing them into darkness. "Now that... that was a fuck to remember." she yawned sleepily. Lizzy wrapped her arms around one of his arms and snuggled close to him.

 

[Orgasmicallyfun]

The three of them laid there all in post orgasmic bliss. The sheets on the bed had wet cum stains all over them also they had a copious amount of cum on their bodies but they didn’t even bother cleaning up. The two girls snuggled into Matt’s side their warm soft breasts pressing against his chest. “Hell yeah it was!” Matt said looking over at Stacie and when their eyes met he leaned in and gave her a deep kiss.

Once their kiss broke he turned to look at Lizzy and leaned in to give her a kiss just like Stacie. He wanted this night to keep going but his body was exhausted as he was sure Stacie’s and Lizzy’s bodies were too. Slowly Matt drifted off to sleep with a smile on his face having fulfilled his fantasy of having a threesome.

 

[Poprockz]

They all slept really well, having exerted themselves quite a bit. The sun was shining its rays through the window; since it was about 9:30, the sun happened to shine right in Matt’s sleeping face, rousing him from his good dreams and becoming him into a sober morning. He awoke to a damp, cum-soaked bed, and two girls on either side of him. He recognized one as Stacie, Lizzy’s best friend. Vague memories of last night were coming back to him. Looking over to the other girl, he confirms his suspicions upon seeing Lizzy’s sleeping face.

Lizzy felt him stir and opened her eyes sleepily, smiling at him. “Good morning. How did you sleep?” She asked sweetly, squeezing the arm she was holding, his arm in between her warm breasts. Looking down her naked body, he could see his cum all over his little sister’s supple skin.

 

[Orgasmicallyfun]

Matt woke the next morning to the morning sun shining on his face. Right away he felt dehydrated like he had a night full of drinking and love making. He could feel damp spots on the bed around him that were still wet from the huge puddles of cum left everywhere. He felt two warm bodies on either side of him. Looking to his left he saw Stacie still asleep. Her big tits pressed up against his body and her leg draped over him he looked down at her big ass and just grinned remembering fucking her from behind last night.

Then he looked to his right and his eyes widened when he saw his little sister Lizzy laying there. Vague memories of him fucking his sister last night coming back to him. He looked her up and down and saw his white cum on her inner thighs and on her pussy. “Oh fuck that really happened!” He thought to himself as his conscious was filling his sober mind with thoughts of how wrong that was.

She woke up and hugged his arm pressing her big breasts against him. “We had sex last night..?” He asked and she could sense that he was starting to panic slightly.

 

[Poprockz]

She looked at him with concern. His eyes were widening and he was starting to breathe a little more quickly. Lizzy could tell that his sober mind was in overdrive trying to process what he had done. Therefore, she chose her words carefully. “Yes, you me and Stacie were intimate last night. I wanted you so badly that I ended up tricking you. I hope you can forgive me.” She gave him her best puppy-dog face as she could, stroking his arm with one of her hands.

Stacie stirred and opened one eye, “Yeah, you practically drowned us in cum. It was awesome.”’

 

[Orgasmicallyfun]

Matt styles laying down trying to process what happened. “You tricked me into fucking you? I’m your brother though we can’t be having sex!” He protested and looked over at Stacie feeling her move and hearing her talk. Taking another glance around he saw all the cum, which looked there were 10 guys in here last night. “So I... came inside of you too?!” Matt asked looking back at Lizzy.

 

[Poprockz]

Lizzy nodded, “yes, you... came inside me. Several times. But I’m on birth control, So we don’t have to worry about getting pregnant.” She scooted closer to him and reached out, laying a hand on the side of his face. “I don’t care that we’re related. All I know is that I want you. Last night was the best night of my life, and I don’t regret a second of it.”

Stacie rolled her eyes, “what’s the hold-up Matt? Back in the day, siblings fucked and married all the time, especially royalty. The fact of the matter is, you’re just scared someone will find out.” Stacie smirked.

 

[Orgasmicallyfun]

“Oh fuck..” Matt sighed softly hearing that he came several times inside of his sister. When she moved closer it caused her bare pussy to rub against him so now both teens had their bare pussies rubbing against him. He tried fighting it but between that and their big tits rubbing against him Matt started to get hard.

His arm was around Stacie and his hand was on her lower back but she shifted causing his hand to find her big bubble butt that he squeezed. This made him lose the fight of his growing erection and he was now rock hard. “But it’s so wrong..” he protested again but they could both hear the want in his voice.

 

[Poprockz]

“So fucking wrong...” Stacie whispered in his ear, giving it a long kick before starting to suck on his earlobe.

Lizzy grinned, hearing him starting to come around. She glanced down and saw that he was standing at attention once again. “I’m pretty hungry. Maybe I’ll take breakfast in bed.” She sat up and turned around, crawling down to his cock. She then rested on top of him, her warm body pressing into his with her breasts resting near his cock. Her pussy was tantalizingly close to his face, obscuring his view.

He felt something warm and wet lick the head of his cock. Lizzy then took her tongue and slowly ran it up and down the length of his shaft, leaving a trail of saliva as she went. “Mmm. Just what I wanted.” She murmured as she continued sliding her tongue across his skin.

 

[Orgasmicallyfun]

“Oh god..” Matt groaned softly when Stacie whispered into his ear and then started to lick and suck his earlobe. Lizzy moved in bed and laid on top of Matt but facing the opposite way. His eyes locked on his little sister’s bald pussy. His sister’s pussy that he fucked and came inside of several times last night.

“No Lizzy we can’t..” Matt started but was quickly silenced when Stacie pressed her lips against his and began kissing him deeply. Her skilled tongue rubbing against his while his little sister started to lick his cock. A soft groan escaped into the kiss as he felt his little sister’s tongue on his cock. It was so wrong but there was something so kinky and erotic about having his sister do this to him it made his cock throb and grow even harder and bigger.

 

[Poprockz]

Stacie’s mouth was intoxicating the way she dominated his own. Her lips and tongue made it clear that she wanted to taste him, and that she would get what she wanted until she was satisfied. One of her hands firmly held the back of his head, pulling him back to her when he tried to pull away.

Meanwhile, Lizzy moved her mouth to different spots along his shaft, kissing and sucking gently on him. Her hands rubbed his thighs sensually as she worked on his throbbing pole. “You taste so good, Matt. I can’t wait to have more of your cum in my mouth.” Lizzy sighed softly.

 

[Orgasmicallyfun]

The way Stacie kissed Matt had him addicted to her kisses. He didn’t want it to end, the way her tongue and lips moved in the kiss was intoxicating. His hand on her ass resumed squeezing and caressing her juicy ass and his other hand placed on her neck while they made out. Her kiss was so good it was distracting Matt from the fact that the girl who was sucking his cock was his little sister.

“I have such a naughty sister wanting her own brother’s cum in her mouth.” Matt groaned out into the kiss, Stacie’s tongue never leaving his. The way Lizzy was laying had her pussy so close to their face he could smell his sister’s sweet arousal.

 

[Poprockz]

Lizzy moved back up and enveloped the head of his cock into her warm mouth, swirling her slick tongue around it several times. She then started to take more of him in, using the suction of her lips to stimulate him as her agile tongue wiggled on the underside. She moaned with him in her mouth, loving the feeling off power it gave her.

Stacie suddenly pulled away from him and clamped a hand on his mouth, moving very close to his face. “Tell me you want your little sister to swallow your seed.” Her hand relaxed on his mouth, allowing him to speak. She hovered her lips just out of reach of him, licking her lips to tease him.
