Sister's heat
Spencer furiously tapped on his keyboard, trying to flank the players he was playing against in the online shooter. The young feline was too busy concentrating on his game to notice his sister had entered the room.
"Bro?" Jackie mumbled. Spencer was focused on the glaring screen, the headphones in his ears drowned out his sister's quiet demeanor. Jackie stood in the doorway to her brother's room awkwardly fidgeting with her hands behind her back. She stood there a moment waiting to see if her brother would notice her standing there. However the match was extremely close, Spencer's focus was entirely on his game. Jackie huffed in frustration. Feeling ignored she walked up behind her brother and tapped him on the shoulder. Startled Spender nearly jumped out of his seat, an earphone flying out of his ear as he spun his head around.
"Jesus Jackie!" Spencer felt his heart race. "Don't sneak up on me like that." The feline turned his head back to the screen only to watch his character die. Annoyed Spencer sighed and rested himself on the arm of the chair.
"Sorry..." Jackie turned her head away.
"What's up sis?" Jackie turned her head away.
"Why have you been ignoring me?" Spencer felt a lump form in his throat, turning his head away as well as he couldn't face his sister. It was true. Ever since the night of her sleepover Spencer had been distant. Originally it was because he thought he might have gotten her pregnant. Even though only a little got inside he was paranoid everyday following that night. Looking up the symptoms of pregnancy and closely observing his sister. That's when he learned that the likeliness was very low, unless she was in heat. But Spencer didn't want to take any chance, that's why he had been evading her. Anytime they were left alone he preoccupied himself with something or made excuses.
"I'm not ignoring you." Spencer lied focusing his attention back on the computer screen. He fixated on his dead character, in the corner of his eye he could see his sister look up at him.
"Yes you are." Her sweet voice went right through his heart. Spencer sat there in silence for a moment.
"We shouldn't have done what we did," Spencer finally said.
"But you said you loved me..." Spencer groaned at the comment.
"Of course I do Jackie," he scratched his head furiously. "It's just-" Spencer was interrupted by his sister jumping into his lap. Jackie straddled him, arms crossed.
"Just what?" Spencer moved his sister onto his knee to prevent any friction between her groin and his member. He sighed; he didn't want to make this anymore complicated.
"You're' right," he patted her knee, "I'm sorry I've been avoiding you." A smile came across her face. Spencer figured he could spend more time with her while also avoiding more intimate contact. "Tell you what. Tomorrow we'll ride our bikes to the theater and we'll see a movie. How's that sound?" The smile of Jackie's face grew wider. She threw herself onto Spencer, giving him a big embrace. Her knee hit him in the stomach, knocking some of the wind out of him. "Oof- Alright, alright. Now let me get back to my game, you killed me earlier."
The next morning
Spencer zipped up his dark grey hoodie, it was a bit colder today and riding a bike in the wind would only intensify it. Plopping down onto the couch he patiently waited for his sister. After a couple of minutes and nervously checking his watch he started to question why his sister was taking so long. It wasn't until his mom came out all dressed up that he got his answer.
"Hey mom, you going to work? It's Saturday."
"Yeah," she adjusted the cuffs on her coat, "your father left for the firm earlier and I was just called in."
"You guys have important lawyer stuff to do?" He asked. His mother smiled, moving the hair out from in front of her face.
"You'll be a lawyer in no time with all that knowledge." With a check of her watch she quickly headed towards the door.
"Hey mom Jackie and I were supposed to go to the movies today but she hasn't left her room all day."
"Oh. Well it's that time for her right now, sorry sweetie." Her voice called out.
"Her time? Oh." Spencer quickly answered his own question. He sighed slinking into the couch cushion.
"I'm sorry; I know she was looking forward to it. But while we're gone can you keep an eye on her? She should be fine, but just in case?" She gave a pleading smile while digging for the keys in her purse.
"Yeah..." Spencer huffed.
"Thanks hun!" We'll be back as soon as we can!" And with that his mom left leaving the two alone. The teen sighed, drumming a beat on his thighs.
"Welp," Spencer, while upset, felt worse for his sister. He was looking forward to the movie, but he knew Jackie was looking forward to it even more. Shedding his hoddie he made his way upstairs towards his room. But not before stopping by his sister's room. As he went to knock on her door he was stopped by a muffled noise. He pressed his ear to the door, but quickly shuffled away in embarrassment when he realized it was a vibrator he was hearing. Retreating to his room Spencer booted up his computer deciding to pass the time with what he does best. It wasn't long before he was completely engrossed in his game. He was on a roll; top of his team in kills and bottom in deaths. It was his third game and it seemed like there was no end in sight. He was fully immersed, until he caught a whiff of something bringing his streak to an end. Trying to shake it off he refocused. But it was messing with him subconsciously; he found himself becoming aroused and his body warm. Now he was dying more than he was killing. It was a scent, a subtle scent floated around his nostrils.
Curious, Spencer inhaled deeply through his nose. Spencer immediately perked up, mouth almost watering. Pulling his headphones off he spun around in his chair so fast he almost went all the way around. In his doorway stood Jackie wearing a loose t-shirt and panties, her hands were tucked between her legs.
"Jackie!" Was all Spencer could manage.
"Bro... Can we do it please? Like we did that one night?" Spencer was dumbfounded at her forwardness.
"I-uh. We-." Spencer was fighting a losing battle against the raging boner in his pants. "We can't."
"Why not?" Jackie pouted. "I learned about this! Whenever this happens we're supposed to have sex!" Spencer yanked his headphones out of the computer to ensure the microphone on it didn't pick anything up.
"Cuz last time was risky enough! If I get even a little bit of sperm in you, especially now, you could get pregnant!" Jackie's seemed to calm down after that comment. Spencer scratched the back of his head. "Look, let's just wait until this passes over. If you still want to do it then, then we will."
"What about condoms!" Jackie perked up. The thought of buying condoms sent a wave of anxiety through the young feline.
"I'm not biking to the store to buy condoms. What if I run into one of mom or dad's friends?" While that was partially true, he just didn't like the thought of having to go buy them and feel the cashier judge him. "Plus I don't have any money." Once again Jackie's mood soured.
"Hmph." Jackie crossed her arms. This gave Spencer a view of how wet her panties actually were. The scent was overwhelming; the young hormone riddled teen fought against his urges. He had an idea though; his leg nervously bounced as he thought if he should say it or not.
"Well there's something else we can do though," Spencer spoke his thought. Jackie looked intrigued.
"What?"
"Well..." Spencer bit his lip. "We can try anal."
"Anal?" Jackie asked curiously. "What's that?"
"It's when you do it in the butt instead of the vagina." The teen's heart was racing at the thought of her reply.
"My butt?" She placed her hands on her butt. "That seems weird." Spencer was afraid of this.
"Fuck. She going to think I'm a freak. God damn it why did I suggest this."
"Do animals actually do that?" Jackie asked, more out of curiosity than disgust. "Wouldn't it be too big?" Spencer saw the curiosity in her eyes and took advantage of the situation.
"Y-yeah! All the time! It just takes practice is all! Come here I'll show you." Spencer turned back to his computer and closed out his game. Bringing up the internet browser he pulled up his favorite porn site. As he entered the search and looked for a good video he saw Jackie out of the corner of his eye stand next to his chair. Finally he found what looked like a good video; a cheetah girl taking a thick dog cock in the ass. Spencer skipped past the stripping and blowjob part to get to the main action. He clicked on the timeline bringing the video to a point where the cheetah was roughly riding the dog. The cheetah was moaning and demanding the dog spread her ass wider for the camera. Spencer couldn't help but grope himself. He noticed that Jackie was as well, her hand in her panties not so subtly rubbing herself. The moment lasted less than a minute. Spencer didn't want to get too aroused and do something stupid. He closed out the window to the disappointment of Jackie.
"Here," Spencer stood up, taking the laptop off of his desk. "I'll lend you my laptop for a few days so you can watch some more videos to help you learn." He wasn't sure if that's how it worked, but if she saw more videos of girls doing it then she might find the idea of it more appealing. "So you can watch videos on the site I just showed you or look up some of your own. Just stay away from shady looking websites okay?" Jackie looked at the laptop as if it was the Holy Grail. "Take a few days to practice okay? Start with a finger then work your way up."
"Should I use spit to help like the cheetah did?" Jackie was inching her way out, eager to get started on all the videos.
"Hold on." Spencer took off towards his parent's room. Digging through their drawers he stumbled across things he wished he hadn't, but he found what he was looking for, lube. Back upstairs he handed the bottle to his sister.
"Use a little at a time. Be patient and you'll be all good." Jackie took the bottle, reading the labels before looking up with a smile.
"Thanks bro." She gave him an awkward side hug with the lube and laptop in her hands. "I'll practice as much as I can so I can be just like the cheetah!" The girl ran into her room; probably to take care of her "issue". Spencer sighed with relief, glad that she took it really well. Though he couldn't help but giggle at the situation as this isn't usually a conversation between siblings. Now that he was relaxed, the feline quickly rushed into his room to take care of his own issue.
The next three days for Spencer were spent wondering if his sister was actually going through with it. The only time he saw her was for dinner. Even then she was silent, and would only briefly look up from her dinner to give him a quick smile before returning to her meal. She spent a majority of the time in her room. At night Spencer could sometimes hear the faint buzzing of a vibrator or the muffled cries of passion for her brother. Every time he cringed, hoping their parents didn't hear. Finally it all came to a head one day.
Spencer had just returned home on his bike after spending some time with some friends at the park. They had snuck off into a canyon off to the side where one of his friends, a snow leopard, had brought some weed and a pipe. Even though the leopard was only a year older than the rest of the group there was an overall maturity difference. Everyone one was surprised he had brought it. While everyone else smoke a bunch Spencer only took a hit, the coughing being too much for him. He arrived home a little wobbly; being a first timer it decently hit him. Luckily his parents weren't home from work so he had time to shower the stench off and change clothes. The rest of the day was uneventful; Spencer did some homework and ate dinner with his family. It wasn't until he went to sleep that it happened.
Jackie silently closed her brother's door behind her, stepping as quietly as she could to his bedside. She looked over her brother, his chest peacefully rising and falling in his sleep. Carefully she climbed nude onto his bed as to not wake him. She sat down next to him and gently pulled down the sheets as slowly as she could. The fabric slid down past his chest, belly, and finally his groin, exposing the flaccid red flesh. With her panties soaked and nether regions on fire, Jackie wasn't hesitant to grip her brother's cock. Her thumb rubbed over the head of his sensitive penis. It was enough to make Spencer stir in his sleep, but not enough to wake him. Jackie massaged the head with her thumb causing the rest of the member to engorge. It didn't take long for him to be at his full five inches. Jackie had to switch to using both hands as one of her tiny hands couldn't wrap all the way around the thick member. Once at full mast Jackie bent over, ass in the air and face inches from the warm member. With a lick from the base to the tip she wet her brother's cock. At the top she engulfed his member taking it in half way.
Spencer was roused from the warm feeling coming from his groin. Initially he thought he had wet himself as he couldn't see anything in the dark. Though after blinking a few times he could see the figure moving up and down in the dark. With the warmth around his cock he put two and two together.
"J-Jackie!" Spencer stuttered, his voice catching in his throat. The pleasurable feeling made it hard for him to speak. His claws dug into the sheets as he moaned. As his feline eyes adjusted to the darkness he could see all the techniques Jackie was using. She was much more enthusiastic this time around. The young feline bobbed her head quickly then would switch to slow movements, allowing the head of his penis to drag on the roof of her mouth as she looked up at him. Those innocent eyes held such lust behind them. She was very sloppy with her blowjob but in a good way. Using enough saliva so that when she switched to jacking his cock there was enough to lubricate it. Jackie had switched to using her hands; furiously jacking his cock while dragging her tongue along the tip of his cock.
"E-easy sis!" Spencer gripped Jackie's wrist, stopping her before she made him cum. "I'm guessing you learned some of that from the videos?" Jackie nodded cheerfully, prideful that her brother enjoyed her newfound skills. "Well if you keep that up I won't last much longer."
"Oh!" Jackie quickly wiped the saliva from her face. "Let's switch it up then!" Before Spencer could reply Jackie was crawling on top of her brother. She was quick to position herself above her brother's face, turning around so she could still play with her brother's dick. Spencer could feel the heat coming off of her on his face. The rush of hormones kicked his instincts into overdrive, immediately lapping at her dripping cunny while placing his hands on her hips. She tasted fresh, as if she had prepped beforehand. Jackie softly moaned as he pleasured her. All the while she continued to gently stroke his penis to keep him excited; and it worked. Spencer's tongue furiously worked around her clit, as if doing a good job would be rewarded with more pleasure. But Jackie kept it slow to ensure he didn't finish all over himself.
"That's it bro!" Jackie encouraged. "Eat my pussy!" Spencer was shocked. That was the first time something like that had come out of her. He reckoned she also picked up some porn lingo as well. "Keep going, just like that." The more she talked the more comfortable she seemed with talking dirty. "You like eating your sister's pussy?" Spencer felt his balls jump and his dick harden even more with that comment. Jackie felt his member throb in her hand too. "Oh? Someone likes that." Jackie sat upright letting Spencer's cock slap against his belly. Almost forcefully she started grinding her hips, sloppily rubbing her vagina practically all over his face. Spencer struggled to keep up. Deciding to take back some control he guided her hips, showing her to move in smaller circles so he could still pleasure her clit. Once she got the flow of things Jackie took back control, moving his hands over her small breasts so he could play with her nipples.
"You dirty boy, you love having your sister sit on your face?" Spencer was in a trance, practically a slave to his sister. "I didn't hear an answer!" Spencer suddenly snapped back to reality.
"Mhmm," he answer, muffled by his sister's pussy over his mouth. The vibrations tickled her, sending a light shiver down her spine. Placing her hands on her brother's stomach for leverage she raised her hips off of Spencer's face, her legs a bit shaky to support her on their own. A small string of fluid connected his tongue to her slit but was quickly lapped up by Spencer. The teen was lightly panting with his tongue out, having enjoyed being his sister's chair for a bit. Jackie wasn't done though. She shifted forward just slightly lining up her second hole for Spencer. Spencer hesitated for a second, eyeing her tight pucker.
"You still have some of that lu-" Spencer started, but was interrupted by Jackie planting her cheeks back down on his face.
"You'll stick it in there but won't eat my ass? You're lubing it up like they do in the videos." Jackie ordered. Spencer didn't know where this new attitude came from. Maybe being in heat was doing this to her. Either way he liked it. "Come on brooo." Jackie stroked his cock for encouragement. With that all doubt went away as he dragged his tongue across her tailhole. She shivered at the new sensation. It wasn't like getting eaten out, but it was still enjoyable. Spencer started with a few slow drags of the tongue to start, warming her up. Then he went to small circles, further lubing up the entrance to her hole. Tentatively he pressed his tongue against her tailhole. He felt her tense up for a second at the sudden pressure. Spencer gently rubbed the inside of her thigh, relaxing her enough for his tongue to slip inside.
"There you go..." Jackie sat up slipping a finger in between her slit. She rubbed her clit for double the pleasure as Spencer's tongue reached as deep as it could. He wriggled his tongue all along her walls coating the inside of her with his saliva. Spencer tongue fucked his sister's tailhole, getting it nice and slick. It lasted only a moment as Spencer determined it was wet enough for him.
"That should do it sis," Spencer said taking his tongue out of her ass.
"Aww, that was good too." Jackie spun around placing her hands on his chest.
"Well if tonight goes well then we can always do this again." Spencer took a hold of her hips, guiding her down to his waist.
"Promise?" She bit her lower lip as the tip of his penis prodded against her ass.
"Of course," Spencer replied, the tip of his cock popping inside her anus. Jackie sucked air in through her clenched teeth.
"Ow."
"You alright?" Spencer asked concerned.
"Mm-yeah. It's not too bad. Just give me a second." Jackie placed a hand on her brother's groin to ensure he wouldn't thrust upwards. She knew that it would just get thicker from here. She was starting to question how this could feel as good as it does in the videos. Timidly she started down his shaft, spreading her ass with her hands to help the process. Spencer had to use all of his internal strength not to plunge deep into his sister. The inside warmth of her ass was titillating. Halfway down his length, the thickest part, Jackie gasped as something inside her switched. With a little more pressure the rest of his cock was practically sucked inside her. She felt a sense of fullness, her legs slightly shaking from the sensation.
"Oh wow." Jackie placed her arms on her brother's chest to support her legs. It was a little uncomfortable for him, but she was so light it wasn't too big of a deal. Spencer caressed her lower back, running his hands through her soft fur down to her supple cheeks. Squeezing and spreading her cheeks he couldn't help but play with them. He could feel her tight anus gripping his cock.
"Good huh?" Spencer grinned. Without answering Jackie began moving ever so slightly; with short methodical bounces. Even though she was barely moving half an inch Spencer could feel her entrance clenching around him. Though he was enjoying it, things were moving too slow. With his hands on her ass he "encouraged" her by lifting her up some more as she went up. Jackie was getting more into it by the second. Eventually she was bouncing all the way up and down his member with such ferocity her cheeks were clapping against Spencer's groin. They were both huffing and moaning in ecstasy.
"Nn-so good." Jackie slammed down once more. This time she moved her hips, wiggling them and moving in circles so she could feel his cock move around inside her. Spencer played with her clit as she wiggling around. She was practically dripping from her slit from the intense pleasure.
"I love the feeling of your dick in my ass," Jackie exclaimed, continuing with the language she learned. Her legs shaking and tensing up as she could feel her orgasm drawing closer. Spencer decided she shouldn't be the only one talking dirty.
"That's it sis, ride my cock." They both looked at each other and smiled. While they both seemed to like talking like that, it sounded a little bit silly. Spencer didn't want to break the moment though. He brought his hand from between her legs and pulled in, planting his lips on hers. It was clumsy and awkward due to Jackie's inexperience. She wasn't very good at multitasking, focusing more on riding his dick than kissing. "This isn't working." Spencer thought; he'll have to teach her later. Spencer broke the kiss and guided his sister off his member. Jackie looked confused for a second but quickly changed to a grin as Spencer laid her on her back. Spencer hooked his arms behind her legs, moving them to the side of her head making her butt lift into the air. He easily slid inside her this time with most of his weight resting on her ass. This way he could be the one multitasking. Kissing her again he tried guiding her as his groin slapped against her cheeks. The kiss started out gentle, showing her lips with his what to do. Then as it progressed he moved his tongue into her mouth. He didn't want to over complicate it so he kept it slow. Their tongues slowly slid across each other, Spencer paused to nibble on her lower lip then continued. His balls smacked against her soft fur as he continued to thrust. He could feel himself becoming for sensitive by the moment. He wanted to try one last position before finishing. The feline buried himself deep in his sister, pausing his movements to nibble on her neck. It was then that he noticed how much the two of them were purring.
"Turn over." Spencer said taking his cock out of her. Jackie was eager and compliant, quickly turning over onto all fours. Flicking her tail out of the way she presented her ass to him. Spencer could tell that her anus was loser now compared to just minutes ago before the pounding. He slid in easier this time, though it was still tight enough to feel nice. Gripping her ass he went at it again. Thrusting with pace so that he could hear his sister moan. Jackie moved Spencer's hands away from her ass so she could spread her cheeks for him. She rested her head on the soft bed sheets. This gave Spencer the freedom to be more forceful with her. With one hand on her shoulder he could get more thrusting force. He was a little rougher with the other hand, placing it on her head forcing her to stay with her head down and ass in the air.
"Nnn-god! You like fucking your sister's ass?" Jackie looked back at him with a sultry look in her eyes.
"God yes." Spencer was panting, building up a bit of a sweat. With her ass spread so far apart he could see how tightly it was gripping him. "You like having my thick cock stretch you out?"
"Fuck yes!"
"You want me to cum inside you? You want your brother's cum deep inside?" Spencer felt he could finish any second, but was purposely going slow enough to hold out. He wanted to hear her say it.
"Yes!"
"Yes what?" Spencer ordered.
"Yes! I want my brother's cum deep in my ass!" With those words Spencer thrust one last time, digging his fingers into her ass to bury himself as deep as he could. He jerked as he shot his seed inside her ass. His balls clenched as he came harder than he ever had. Spencer was filling his sister up with his jizz. With such a hard orgasm his legs couldn't support him and he collapsed on top of Jackie. His cock jerked a few more times, emptying whatever he had left inside her. The two laid there for a moment breathing heavily. They could feel the other's purrs as Spencer lay on top of her. The teen propped himself up on his elbows then buried his face in her neck. Jackie giggled as he licked her neck.
"That was... wow." Spencer ran a hand through his messed up hair. Having came just moments ago his cock was already going flaccid. Jackie continued to purr as Spencer sat up placing his hands on her butt. Spreading her cheeks to get a good view he slowly pulled out, savoring the moment. As his cock popped out a stream of cum trickled down onto the bed sheets. That's when he noticed how wet the bed sheets were.
"Dang you really made a mess." Spencer joked as he ran his fingers through the damp cloth.
"And you didn't?" Jackie quipped glancing over her shoulder.
"Touché." Spencer gave her butt a playful squeeze, slyly wiping his fingers off on her before lying down next to her. "So..." The teen traced his fingers down the small of her back, "did you enjoy it?" Jackie flicked the hair out of her eye, giving him a look.
"Do you really have to ask that?" She flicked her brother on the nose. "I'm super tired now though." She outstretched her arms yawning heavily.
"Yeah that took a lot out of me as well." Spencer grabbed a pillow and nuzzled into it. "You can sleep in my bed, if you want that is." Jackie however was already pulling sheets over herself.
"Mmm, I clean up in the morning." Jackie closed her eyes settling in comfortably in her spot. Spencer grinned; looking at her sister she looked cute lying there with her eyes closed. Petting her softly on the head she purred contently. He knew their relationship would never be the same after that first night. But now it seemed different, and he knew things would be different; though they also had to be careful. Looking at her peaceful face innocently sleeping there Spencer figured it was worth the risk.
