“What’s that?” Sienna asked, spotting the metal case in her brother’s hand. She sat up straighter. Her online lectures were done for the day and she was thankful for a distraction.
“None of your business squirt,” Callum replied. He set the case down on the table and walked over to the coffee machine. Switching it on before turning and resting his ass on the kitchen side, facing his sister.
“Don’t call me that!” she whined, then immediately regretted her tone. She always tried desperately to not let him get to her. She took a deep breath. “Seriously though, what is it?” She ran her fingers through her long blonde hair, well, almost blonde, her dark roots starting to show through. She knew she needed to sort that out.
“Something from work we’ve been working on,” Callum said. “I wanted to try it out over the weekend.” He waited for his coffee, glad it was Friday at last. It had been a tough week and he needed to unwind. He still had a bit of work to finish, nothing too taxing, a bit of testing, and then he could do whatever he wanted.
“I was hoping for your help actually,” he added. He watched his sister look up and stare at him suspiciously.
“With what?” she asked.
“I’ve been working on a lie detector,” he said, his eyes flicking to the case. “It’s supposed to be unbeatable. I’m pretty confident in it, but it needs more testing.”
Sienna thought for a second, her brain addled by her lectures. She decided it would be a laugh.
“I’ll do it, if you go on it after, and I ask you questions,” Sienna said, losing herself slightly in his bright green eyes.
Callum thought hard, he knew how good the machine was. He didn’t see any harm though, and it was a good test. “Okay,” he agreed.
“Yes!” Sienna said, excited. She jumped up. “I’ll just get dressed.” She hurried out the room and Callum watched her go, his eyes falling to her slender legs beneath the white baggy t-shirt she was wearing. It was long and looked like she had nothing on her bottom half. Maybe she didn’t, he thought. He shook his head and turned to finish making his coffee.
“She’s grown up,” he muttered. Shame trickling through him. His younger sister wants 18 now, and had grown into a very attractive young woman. He shook his head again.
Callum was sitting at the table when Sienna came back in. It took every ounce of his self control not to look over her body.He knew what she was wearing, having checked her out plenty of times in it.
Sienna smiled inside as she watched the inner struggle of her brother. She knew the black leggings she wore and the blue crop top made him uncomfortable. It showed plenty of skin and highlighted her perfect slender body and firm round breasts. She knew it was wrong, but there was something about the glances he gave her that made her feel good. Wrong, but good. There was no harm in a few fantasies, she thought.
“I’ll just get a drink,” she said. Callum took in her body again. The tight leggings highlighting her long slender legs and perfect round ass. They were low on her hips and her ribs tightened her skin as she reached for a glass. Her thin, toned waist visible beneath her crop top.
Sienna poured herself some juice and went over to the table. She plonked herself down into the chair opposite her brother.
“Where do we start?” she asked. She was glad their parents were out. It was always nice to spend time with her brother. There wasn’t enough of him lately, what with her studying and his work. She missed him.
They had always got on. The occasional brother and sister argument, but generally they enjoyed each other’s company. And he’s quite easy on the eye, Sienna thought. His short, perfectly styled blonde hair. His naturally lighter. His handsome features and an athletic physique. He was just over 6 feet, so had quite a few inches on her. Which she liked in her men.
She watched him stand and put the metal case on the table. He opened it and took out a small black box, pressing a button that made a blue light come on. He looked good in his work stuff. Smart trousers and a blue shirt.
Callum moved and stood above his sister and brushed her hair behind her ear, noticing the shiver that ran down her spine. He attached a small node to her temple. His eyes drifted to her cleavage, her firm breasts pushed together in the V of her top
“It’s not very big,” Sienna said, looking up. Callum nearly jumped and pulled his eyes away. Looking into hers. Recovering nicely.
“Size isn’t everything,” Callum said, smiling. He winked.
“Ew gross,” Sienna said. “Number one in the top ten things you never want your brother to say. And the wink just made me sick a bit in my mouth.”
Callum laughed. “Now sit still whilst I calibrate it.” He started pressing buttons and turning dials.
“Is it a yes and no jobby?” Sienna asked, starting to feel nervous. She wondered why she agreed to this. There were certain secrets in her head that maybe she didn’t want to reveal to her brother. No scratch that, definitely didn’t want to reveal.
“No. It can read whole sentences,” said Callum. “That’s what makes this new one so special.” He pressed a button and it hummed gently to life.
“Oh that’s good,” Sienna said, nervously. The computer made a sound like you get when you answer a question wrong on a game show. EEH EEH.
“Your first lie,” Callum said, grinning. “Starting to feel nervous, Squirt?”
“No!” she said. The same noise. Callum laughed. “Oh for fucks sake.” She had definitely made a mistake here.
“Okay. Let’s start,” Callum said. “Some obvious questions first to just check if it’s working. Is your name Beryl?”
“No. My name isn’t Beryl,” she said. The computer went ping, the truth.
“Are you a pygmy goat?” Callum said, grinning.
“Yes I am,” Sienna laughed. He knew she liked pygmy goats. EEH EEH. “Phew. That would have been a shock.
“Am I your brother?” Callum asked.
“Unfortunately you are,” Sienna joked. Trying not to use yes. She wanted to see how good this thing really was. PING.
“Good,” Callum said. He leant back in his chair, thinking.
“Don’t be mean,” Sienna said. “Remember I’m helping you.”
Callum smiled. “Wouldn’t dream of it,” he said. He leaned forward. “Do you like my art work?”
Sienna laughed. “Dickhead,” she said. “Yes I do.” The machine pinged. The truth. “After some praise are you.
Callum smiled. “Just checking you weren’t just being nice,” he said. He liked to sketch and sometimes paint in his spare time. Sierra always encouraged him, he just wanted to make sure she wasn’t being kind when she said they were good. “Thank you.”
“Have you ever stolen anything?” he said, a quick change to catch her off guard.
Sienna stuttered. Blushed. She decided it was best to tell the truth. “When I was 8 I stuck a pink pencil into my coat pocket,” she said. “It was in the old local shop. I’ve felt guilty ever since.”
Callum laughed. “You rebel,” he said. “I promise not to report you.”
“Hey. I’m a good girl,” Sienna said. “That moment was a blip in my honest and flawless personality.” She smiled sweetly and Callum admired her pretty features.
“I’m sure there’s some darkness in there somewhere,” Callum said. “You can’t be all sweetness and light.”
Sienna dramatically placed her hand over her heart, almost cupping her firm round breasts. Callum couldn’t help but look,and looking back up quickly.
“How could you say such a thing?” Sienna replied, just as dramatically as her pose.
Callum thought hard. There must be something on her he thought. Too many inappropriate questions flooding his mind.
“Do you have a boyfriend?” he asked. This was the least inappropriate he could think of.
“Bit personal,” she muttered. “No I don’t.” The machine pinged.
Callum felt a strange sense of relief at the truthful answer. He then realised an error.
“Girlfriend?” he asked. His sister’s eyes narrowed.
“No,” she said. The machine pinged. “I am not romantically involved with anyone.” If he asked a few weeks ago it might have been a different noise from the lie detector. Her recent relationship, with a guy, had ended a bit messily. The usual, he wanted more, but she wasn’t ready for that kind of commitment from him. She was disappointed because the sex had been good. She remembered it fondly and felt a stir in her lower abdomen. It had been a while since then.
“Your love of Justin Bieber scare them off?” Callum said, laughing.
“Fuck you,” Sienna said. She gave him the finger. That was years ago but she knew he loved teasing her.
“You wish,” Callum said. An automatic response.
“Yeah right,” Sienna started, forgetting she had the lie detector on for a second. “I wouldn’t want to go anywhere near you.” EEH EEH. The computer highlighted the lie instantly. Sienna blushed. Callum gave a sly smile. Interesting, he thought.
He knew it was wrong but he couldn’t help embarrassing his sister, time to step things up. “How often do you masturbate?” he said.
Sienna’s mouth opened in shock. “Never!” she said, not thinking again. Her mouth went into defensive mode. The lie tone. “Well, I might do it occasionally.” EEH EEH. Callum laughed.
“Tell the truth now sis,” Callum said. A big grin on his face.
“I’m not answering that,” Sienna said, defiantly.
“Remember you get your own back after,” Callum said. Now feeling slightly worried about pushing his sister too much. It would be worth it though, he thought.
Sienna considered this, and thought too that it would be worth it. How bad could his questions get? And she was sure her self pleasuring was pretty normal.
“Most days,” she said quietly. The machine pinged.
“What was that sis?” Callum asked, he had heard her perfectly, but was enjoying making her squirm.
“I play with myself nearly everyday,” she shouted, the machine pinged again.
“That’s quite a lot,” Callum laughed.
“Not as much as you,” Sienna said. “I hear you all the time, your bed banging the wall.” Callum’s smile dropped off his face. A ping.
“Well you shouldn’t be listening,” he said sulkily.
“Well I don’t listen on purpose,” Sienna said, the computer spotted the lie. She flushed red. Callum grinned.
“So you listen to me wanking then?” he asked. He felt his cock hardening in his trousers, he knew he shouldn’t whilst talking about this stuff with his sister, but he couldn’t help it.
“It’s hard to ignore,” she replied, looking down at the table. PING. The truth. “Can we change the subject?” She too was starting to feel aroused by this conversation.
“Not yet,” Callum said.
“Have you ever fantasised about a family member when you play with yourself?” Callum said.
“Ew gross! No way, ” Sienna said. EEH EEH. “No fucking way, that things rigged, or you’re pressing the buttons.” She crossed her arms hoping he believed her. She knew she was lying though. Callum ignored her.
“Is it dad?” Callum asked.
“No,” Sierra said, knowing what was coming. EEH EEH. She flushed bright pink.
“Holy shit,” Callum said. “Mum?”
“No, definitely not,” Sienna nearly shouted. “And if that thing fucking says anything different.” It pinged. Relief washed over Sierra, she wasn’t interested in women.
“What were you doing with dad?” Callum asked.
“Were you fucking him in your fantasies whilst getting off?” he asked.
“None of your fucking business,” Sienna said. The tone in her voice itself was answer enough for Callum to leave that one alone, but he needed to know something else.
“Do you ever fantasise about me?” he asked.
“God no!” Sienna answered, almost shouting. As soon as it left her lips, she cringed. EEH EEH.
Callum smirked, finding it hilarious, but he couldn’t deny it turned him on, the hardening in his underwear proved that point.
“What do you fantasise about?” Callum asked. “What do we get up to?” His sister had an amazing pink glow in her cheeks. He couldn’t help but find it incredibly cute.
She knew how screwed she was hooked up to the bastard lie detector. The emotions running through her body screwed with her self control. She decided to just come out with it.
“It’s only a fantasy,” she said. “It’s too weird to be real, but I can’t help it. Sometimes I want………” She paused. “Think……what it would be like to have sex.” The machine pinged.
Callum nearly choked, but kept it well hidden. Holy fuck, he thought. He had definitely had those thoughts himself, but he was a horny teenage boy with a hot sister. He never imagined she felt the same way. This had escalated way too quickly.
“Are you thinking about it now?” he asked.
“No,” Sienna said quietly. EEH EEH. “For fucks sake.” She was flustered now, the rising heat between her thighs making it hard to concentrate. Callum’s studying gaze wasn’t helping.
“Are you turned on now?” Callum said. She didn’t answer, but he could see she was. He knew because of how turned on he was.
“Do you want to touch yourself?” Callum asked. His cock now raging in his jeans. He looked at his sister’s flushed face.
“No,” Sienna said, quietly. Callum didn’t need the machine to tell him it was a lie, but it did. Sienna let out a soft moan, her hand was on her inside thigh, so close.
“Touch yourself,” Callum instructed.
“It’s wrong,” she said, quietly.
“I know you want to,” he said. “I want to see it.”
Sienna couldn’t stop herself from obeying him as her hand went between her legs, she moaned. She pushed the fabric of her crotch into herself. Her leggings pushed her panties into herself, wetting them further.
“Does it feel good?” Callum asked. He couldn’t see what she was doing under the table, but he could imagine, and it turned him on a lot.
“Really good,” Sienna said, pushing harder and slowly rubbing. PING. The truth. She moaned.
She’s so pretty, Callum thought, enjoying how much his sister had grown into a gorgeous young woman. He couldn’t see what she was doing, but just seeing the expression on her face was hot enough.
Sienna rubbed herself harder through her leggings, her arousal growing quickly. The thought of her brother opposite was intoxicating. She moved up to her waistband, easing her hand in.
Sienna’s hand slid inside her leggings and underwear, between her legs, and her fingers between her moist engorged lips. She pushed two into her and groaned again. She watched Callum watching her, knowing she should stop, but couldn’t. She was close to cumming already. She touched her clit and groaned again.
“Do you want to cum?” Callum asked, rubbing his hard cock through his trousers, under the table. She looked so amazing, he thought. Her face was beautiful as she writhed on her fingers.
“God yes,” she moaned. The lie detector told them this was true, but it was pretty obvious. She was sure he was touching himself too. Getting off on her. She worked her fingers faster, so close.
She kept her eyes on him as she played with herself. The fact he was watching her so intently turned her on further. Being watched was another fantasy of hers. She groaned loudly. She wondered how hard he was for her. How big?
A strong wave of pure bliss hit her as she moved her fingers slightly, squeezing her clit between them as they rose in tempo slightly. She squeezed a breast through her top.
“Oh fuck,” she groaned. Her eyes rolling and biting her lip. It came on quickly.
She cried out in pleasure as she orgasmed into her leggings, her fingers working a bit more before pushing into herself and holding on. Her body shook in the chair and she slid slowly down, before grabbing hold of the table with her free hand.
“Holy shit,” Callum muttered. His cock raging to be free and touched. He couldn’t take his eyes off her as she sat there quaking with her eyes closed. He had never seen anything so beautiful. Her body spasmed and twitched. Her breasts heaving.
“I shouldn’t have done that,” she muttered after a while. “That was your fault.” She took her fingers out, they glistened with her juices. She unsteadily stood up. Callum looked at her thin legs in her leggings, her crotch darker with the dampness.
She pulled the node off her temple and placed it on the table, wondering why she hadn’t done that earlier.
“Don’t fucking go anywhere,” she added. “Your turn next.” She unsteadily left the room.
Callum rearranged the raging hard penis straining in his shorts and boxers. Trying to sort it into a less obvious and more comfortable position. Touching it didn’t help the situation though. Watching Sienna cum had made him incredibly horny. He sat there uncomfortably.
After a short while Sienna came back. She’d changed her leggings and was now wearing a short summery dress. Light blue with delicate small white flowers. Thin straps and a plunging neckline. Again showing off her impressive cleavage. Callum eyed her perfect slender legs.
“Let’s forget that ever happened,” she grumbled, plonking herself back down in her chair. She knew that would never happen. She even wanted more. She forced the feeling back down, but she couldn’t deny that fact she had put on her best knickers just in case.
Not fucking likely, Callum thought. “Okay,” he said.
“Your go,” Sienna said.
“Okay,” Callum replied. Part of him wanted to try and get out of it, but the semi hard cock twitching in his underwear wanted to see what happened next.
He picked up the sensor and put it on his temple.
“Do some obvious questions first,” he suggested. “Check it’s working.”
“Okay,” Sienna said, thinking. “What’s your name?”
“Callum,” Callum replied. The machine pinged.
“Correct,” Sienna said, smiling. Callum wasn’t sure he trusted that grin. “Well done.”
“Patronising much?” Callum said, laughing.
“Do you have a sister named Sienna?” she asked.
“Yes,” Callum said. PING.
“Is she awesome?” Sienna said, grinning.
“No,” Callum said. Laughing. EEH EEH.
They both laughed. “Well we know it works,” Sienna said. “Let’s get this show on the road. She sat up straighter, ready for business. Callum squirmed slightly. He was still sporting an erection from earlier.
“How many girls have you had sex with?” Sienna asked. BANG, she thought, make him squirm even more.
“Nine,” he answered. The machine confirmed the truth.
“Slut,” she said. Laughing.
“Fuck off,” he said. “How many have you slept with?”
“Too late bro,” she said. “My turn now.” She was glad he hadn’t asked. It was only 4 and most of them had been disappointingly quick.
Callum cursed himself for not asking the obvious questions.
“Okay let’s begin properly,” Callum said. Trying to change the subject.
“Okay,” she said. A sly little smirk crossing her pretty features.
“Let’s keep it clean,” Callum said. Grimacing at what was coming.
She hit him hard and fast. “Did you give my My Little Pony to Barney when we were younger?” Sienna said.
“Jesus sis,” Callum laughed.
“Answer it.” Sienna said, smiling. They had been a lot younger when their dog Barney had chewed up her favourite My Little Pony. Sienna was adamant she had left her high on her shelf and had always been pretty sure her brother had given it to the dog. Their parents had never believed her. She had gotten over it, but it had always annoyed her that Callum had never confessed.
“It wasn’t me,” Callum said. The machine highlighted the lie. “Fucking things playing up.” He gave the machine a light bang with his fist.
Sienna scowled at him. “I fucking knew it,” she said, coldly. “I knew you were fucking Lying.”
“You ate the last Frube,” he said. “I was angry.” He tried to stay serious but the corners of his mouth turned up.
“Don’t you fucking laugh,” Sienna said. “This is serious. I loved that Pony. Pinkie Pie was my favourite.”
The comment tipped him over the edge and he burst out laughing. Sienna joined him. Callum laughed so hard that tears ran down his face. It took a while for both of them to gain control.
“Prick,” Sienna said. “You will pay for that.”
“I could show you some pretty disturbing comics online that would ruin your childhood,” Callum said.
“Like what?” Sienna said. Her head tilted in interest. She noticed her brother’s eyes drop to her cleavage and quickly back up again.
“Porn comics of My Little Pony,” Callum said.
“No way!” Sienna said. “Really?” She thought quickly. “Hang on…..are you trying to tell me you’ve been jacking off to Twilight Sparkles.”
Callum laughed. “No way!” he said. Luckily the lie detector confirmed this. He liked some pretty dodgy shit but that wasn’t one.
“What type of porn do you like?” she asked. Grinning. It was fun watching him start to squirm, she thought.
“Just regular porn,” he replied. EHH EHH. He watched his sister smile mischievously. Oh shit, he thought.
“Sorry. That was a bit vague,” she said. “Maybe I need to be more specific.”
“You don’t need to,” he said, hopefully.
“Oh I do,” Sienna said. “Anal?”
“Yeah,” Callum offered willingly. He thought that was quite normal.
“Pervert,” she said. She couldn’t imagine wanting anything up her ass. She wasn’t the slightest interested in things up her poop chute.
“Transsexuals?” she asked. This one would be good to have on him, she thought.
“No,” he said calmly. Ping. Callum blew out air in relief.
“Shame. Pissing?” she asked. She had seen all the taboo subjects whilst browsing sites herself.
“No,” he replied. So far so good as the machine highlighted the truth. “You know a lot of categories.”
“Getting fucked with a strap on?” she asked, ignoring his comment. Smiling again. Oh god please, she thought.
“Only girl on girl,” he said. PING.
“Eeewww gross,” Sienna said. She had nothing against it, but again, it didn’t turn her on. Each to their own, she thought.
“Incest?” she said. Asking the one question she had been working towards.
Callums face dropped. “No,” he muttered. Knowing. EHH EHH.
“Interesting,” Sienna said. “Mummy porn, or sister?…… Or even daddy?” She smiled.
“I’m not answering that,” Callum said.
“Wrong,” Sienna said. “I did, so you are.”
Callum sat there thinking. He didn’t want to admit he had fantasies about mums fucking sons, so thought he could wriggle his way out of it. Plus things had already gotten interesting once between him and his sister, so why not see where this leads.
“Sister,” he said, flushing pink. Sienna flushed too, and not just in her face. His ploy worked as she forgot about the mum bit.
“Does that mean you’ve fantasised about me?” she asked, quietly.
“Yes,” he answered. PING. There was no point denying it. The fact he had just fantasised about taking her, whilst she got changed upstairs was irrelevant. That was just one of many.
“Do we have sex in these fantasies?” she asked.
Stupid fucking machine, he thought. Why had he built it so perfectly? “Yes,” he answered. PING.
He shifted uncomfortably. Sienna, noticed.
“Do you have an erection now?” She asked. Remembering his question to her. She knew she was wet again from the questioning. She wondered what was wrong with her.
“No,” he said, weakly. EHH EHH. Sienna smiled.
“Show me,” she said.
“You’re my sister,” he mumbled.
“Didn’t stop you watching me finger myself,” she snapped. She was so horny now it hurt. She needed to see him.
Callum started undoing his trousers, his hand sliding inside his waistband and underwear. He moaned as he touched himself. Not remembering when he had been so hard it ached.
He wrestled his hardness free. Sienna sat up straighter and peered over the table, she only just held back the moan. “It’s big,” she mumbled.
“Thanks,” Callum grinned. It never got old hearing that, even from his sister, apparently.
Callum slowly stroked his cock. It throbbed desperately in his hand.
Sienna stood and walked to the other side of the table, her eyes not leaving the impressive cock in her brother’s hand. It was like an outer body experience. Her legs moving, controlled by the fire burning between her thighs.
She sat on the table in front of Callum, watching him play with himself. She spread her legs, pushing her dress between her thighs. The hem rising up her leg. She ran a hand up her inner thighs, touching herself again. Through the fabric of her dress, pushing it into herself. She moaned softly.
Callum watched her. Seeing what she had done earlier, but more closely. His cock throbbed angrily.
“I want to see you,” Callum said. The machine pinged. His eyes fixed on the hand bunching the dress between her thighs. It was obvious what he wanted to see.
Sienna was lost now. The sight of her brother’s cock had tipped her further into depravity.
Callum’s eyes widened as his sister pulled her skirt up and eased the crotch of her panties aside. Exposing her beautiful shaved slit. She slid two fingers straight into herself. Her pink wet lips spreading around the digits.
Sienna pushed her fingers deep, her tight cunt stretching open for them. She was so wet it squelched slightly.
“Do you want to be inside me?” Sienna asked. She had crossed a line now, and didn’t care. Fucking him was no more wrong than how far they had gone already. That’s what she told herself anyway.
“God yes,” Callum moaned. PING. The machine agreed.
Sienna couldn’t stop herself as she pulled her fingers out of herself and moved over her brother’s lap, opening her legs.
She straddled his lap, taking his hardness in her hand, keeping her panties out of the way, guiding him to her opening.
“Oh fuck,” Sienna gasped as she pushed down. She had never taken anything so big before, but she was so wet. She knew she’d manage.
“Oh god,” she moaned. She pushed down harder, widening her legs. The tip stretched her open, prising her desperate lips apart. She felt herself spread over the head.
“Are you sure?” Callum managed to ask.
“I’m sure,” Sienna moaned. Pain flared as she pushed hard. Then nothing but pleasure. Her eyes rolled to the back of her head as he slipped inside her.
Callum groaned loudly as her tight cunt swallowed the head of his cock, squeezing his shaft. His thoughts now turning to lasting more than a minute before squirting his load.
Sienna moved slowly, rising and falling, trying to stay in control. She took slightly more of him every time she dropped, forcing him deeper inside her. Callum’s hands slipped round her narrow waist.
“Feels good,” she moaned. One of his hands slid up to a breast and squeezed through her dress, the hard nipple sending more waves of pleasure through her.
He pulled a strap over her shoulder and freed one of breasts, he leant down and took the nipple in his lips, running his tongue around the hardened excitement. He had to see all of her.
Callum pulled her dress up and over her head, her braless breasts slipping free. He groaned at the sight of both and took them in his hands.
“So beautiful,” he said, looking up into her eyes. PING. They both laughed before moaning as Sienna rose again and lowered herself hard, forcing all of him inside her.
Callum leaned forward and took the other nipple in his mouth, sucking, kissing, and caressing with his tongue. The other he fondled with his hand.
“Shit, that feels good,” Sienna groaned. He filled her perfectly as she took every inch of him. Like it was made just for her. The ridged swollen member throbbed inside her as she started moving again.
She gripped the table, her flat stomach stretched and breasts pushed out as she lifted herself up and down his length.
“Oh god,” Callum groaned. He ran his hands up his sister’s ribs, taking both of her firm breasts in his hands. Her nipples still solid as he squeezed.
As good as it felt inside her she wanted to see it, to taste it. She stood and he slipped out of her, standing tall and raging with blood. To Callum’s amazement she dropped to her knees and took it in her mouth.
Sienna felt her lips slide over the warm throbbing shaft. Forgetting briefly that it was covered in her own excitement. Remembering too late as she tasted herself on her tongue.
The taste of her own juices fuelled her lust. Shame coursed through her briefly at her behaviour before the throbbing cock in her mouth made her forget it all. Her need burning inside her.
Callum groaned as his sister swallowed him deep down her throat until she choked. She didn’t take much in. Not used to sucking dick.
Sienna had watched enough porn though to know what to do, and she loved the sound he made when she forced the cock down her neck harder. She gagged hard and came back up, gasping.
Her mind swam with a mixture of shame and excitement. The shame because of how much she was getting off on her brother’s hard cock in her mouth. It felt so good, but filthy at the same time.
She ran her tongue up it and then swallowed him in again. This time not so deep, bobbing her head and wanking him off with her lips. She loved the taste of his precum leaking from him.
Callum moaned as his sister worked on his penis. He ran a hand through her blonde hair, holding it out the way so he had a better view of her.
Her slurping sounds filled the kitchen as her lips slid up and down his shaft. He groaned loudly. If he didn’t stop her soon he was going to blow his load.
Callum pulled her up and she moaned disappointingly as her mouth popped off his cock. He sat her on the table. Her ass perched on the end. They kissed hard and his hands went round her thin waist. He lowered her backwards and brought her slender legs up, opening them wide. His eyes fell on her wet thighs and pussy lips. He too needed a taste
Sienna cried out as her brother’s tongue ran up the centre of her, running deep between her sensitive and engorged lips. His tongue probed inside her. She gripped his head, running his fingers through his short soft hair, pulling him into her.
“Fuck,” Sienna groaned. Her hips rising to meet his mouth, pressing her dripping pussy into his face. She moaned again as his tongue prised her open.
His tongue flicked up and found her clit and she cried out, her body bucking as she nearly orgasmed.
“That’s it,” she moaned. “Right there.” He circled her clit with his tongue and she gripped his head, pulling him into her. Her moans grew louder as he teased her with the tip of her tongue.
Callum pushed two fingers into her. Her cunt so wet it took them easily, welcoming them inside her as he pushed them deep. He licked her clit whilst sliding his fingers in and out, exploring and feeling her warm insides. His sister’s juices leaked out of her, need growing and growing.
“Cum,” she moaned. Her arousal was at insane levels. She couldn’t manage much else. “Gonna….”
She orgasmed for the second time that evening. This time on her brother’s mouth and fingers. Her body went rigid, her legs shooting out straight as they shook violently.
Callum stood as his sister rode her climax again. Shaking violently on the table. He needed her so badly. Needed to cause her more pleasure, whilst satisfying his own desire. He waited for her shaking to slow. Rubbing the head of his cock against her swollen pussy lips as she moaned softly, staring into his eyes.
Callum slid inside her again and she nearly orgasmed again, teetering on the edge of ecstasy. Every small move made her nerves blaze with pleasure. The last climax still plagued her senses.
He started rocking his pelvis back and forth and her eyes rolled again, her head dropping back against the table. Her blonde hair spilled across the table top.
“You’re going to make me cum again,” she gasped. “Keep going.” She reached up and behind her. Her body stretched as she gripped the edges of the table above her head.
Callum ran his hands over his sister’s stretched body. Squeezing her firm round breasts and making her groan loudly. He kept moving slowly, the sight of his sister in so much pleasure was incredible.
He slowly built up speed. Sliding in and out of her tight cunt. Enjoying the view of her stretched around his shaft. Her round breasts jiggled every time he thrust forward. He sped up. His hips now slapping her inner thighs.
“Oh fuck, please,” she begged. Still on the edge, desperate now to hit that climax. She had never fully stopped cumming from her last. He felt so deep inside her. Her brother. The thought was all it took.
She gripped the edges of the table hard as she orgasmed again. So close from the last one. She didn’t quite live up to her brother’s nickname for her, but her cunt flooded with her juices as she came all over the cock inside her.
Her moans filled the room as her body shook. Her legs out straight as pleasure shot into the limbs.
Her brother didn’t stop. The pleasure almost too intense as he carried on fucking her. Watching her shake against the table as his own climax built.
She tried to tell him to stop, the orgasm growing in intensity again. She tried to tell him it was too much.
Callum was too close, unable to stop as he continued. Sienna’s pussy squelched with every thrust, her cunt dripping from her ejaculation.
Callum pounded into her, his climax building as his sister writhed beautifully on the table in front of him.
“I’m going to cum,” Callum cried out. PING.
Sienna’s eyes opened to watch him cum inside her. Part of her wanted to see him cum, the other wanted his seed inside her.
She got her first wish as he pulled out and ejaculated hard. His glistening cock exploded up her thin body, a streak of cum hitting her in the neck and chin. She flinched, but smiled. Watching raptly as he unloaded over her breasts and flat stomach. His groans filled the kitchen.
She drank in his body as the muscles in his stomach tightened and relaxed every time he spurted cum over her. The thick white jizz in pools on her sweat glistened skin.
So much, she thought. Her belly covered as it finally started to stop.
“Fuck,” he moaned. His body shaking. He leaned down and they kissed. Lost in the moment. Both breathing hard. They broke the kiss and he flopped against her. She liked the feeling of his weight pressing down into her.
“Next time I want you to finish inside me,” she said softly into his ear.
“There’s a next time?” Callum asked hopefully.
“Only if you want to?” She said, hope in her voice too.
“I do,” he replied.
PING.
THE END.
