Natural Attraction
Natural Attraction
(M Minun + F Plusle)
WARNING: This story contains brother/sister incest...if this bothers you, please bail out now!
Robbie and Robin were a typical brother/sister pair ever since the day they shared their mom's womb. Their mutual bond was also enhanced by the fact that he was a minun and she was a plusle. This would mean that whenever they would touch cheeks affectionately, the opposite charges attracted them to one another, allowing them to share their sparks and feel the other's affection directly. They were close to each other, but their thoughts never went any further beyond what would be considered "normal" for twins...at least until they graduated from high school and moved away from home to go to college.
Robbie and Robin's parents couldn't afford to send them to a more nationally acclaimed college and while the two of them were able to receive grants to allow them to pursue higher education, they could only afford to go to community college. Luckily for them, the college they joined did have cheap apartment space nearby that could be covered by some of the grant money they received, though it would mean they'd have to share the same apartment. However, it did have two separate bedrooms and while the twins had separate rooms ever since 4th grade, they did miss spending time together when they were younger and they both thought it would be nice to share the same apartment together for a while...at least until they could perhaps find someone they could move in with.
However, dating would have to wait a while for the twins as they still needed to get settled into their new apartment and their new life. The grant money provided them with enough money to pay for college expenses for the year with enough left over to afford the apartment space for the two of them. But, they would still need to figure out how they were going to live away from their parents, who had provided them with the essentials up until now...even though they did help Robbie and Robin with some cash to tide them over until the twins could find jobs.
Robbie was unsure of where to look for a job, there were several places hiring around campus, but many of them wanted full-time help. Robin however saw her opportunity right away as they arrived. Not far from the campus, a strip club was holding open auditions for females to come in and apply for the weekend shift. Not only did Robin see this as an opportunity to make good money, the schedule would work out well for her since she had classes Monday through Thursday and the strip club owners wanted dancers that could work Friday, Saturday, and Sunday afternoons on days where there were sporting events.
She had no experience in exotic dancing, but she considered herself attractive enough that she would try. She had violet-blue eyes along with shimmering blonde hair, combined with a "C"-cup bust and a slender build, she thought that she stood a good chance of earning a spot.
The tryout was a few days away, on a Friday evening right before the Autumn semester was scheduled to start, so Robin would have more time to prepare for the coming audition. Still, she felt as if she could use the opinion of a male to determine how good of a chance she had at earning a spot in the audition...and since the only male she knew of in her life was Robbie, Robin decided that she'd ask him.
The night before the audition, Robbie came back from a long day of trying to find a part-time job, unable to find anything that was suitable for his needs as he went directly to the couch and sat down as he was feeling a bit depressed about not finding work. Robin immediately noticed him as he came back to their apartment and immediately sat down with him, placing her hand on his shoulder. "What's the matter Robbie?", she asked him softly as he looked towards his sister.
He sighed for a moment but then spoke. "Nothing...except it seems that I can't find a job. I've tried several different places and all the openings that I've come across were either for full-time or working at a fast-food place", Robbie explained as he sighed once again. "Why can't I find a decent part-time job?", he added as Robin placed her cheek against his as the two of them exchanged a gentle shock.
"Don't worry about it so much, you'll find one eventually...I know you can", Robin answered as Robbie gave his sister a hug before she had an idea pop in her head. "Say Robbie...would you mind doing a little something for me. I have a job interview coming up soon and I need your opinion on an outfit. Could you help me out?", she asked sweetly as Robbie felt happier with his sister by his side.
"Sure sis...anything to help you out", he replied as Robin placed her cheek on his again before she went towards her bedroom.
"Now don't you go anywhere, I'll be right out", Robin instructed Robbie before going into her bedroom and closing the door to change, leaving Robbie on the couch by himself. Robbie thought it was a bit odd that Robin would ask him for his opinion about formal clothing for females, it wasn't as if he knew anything about the subject. Still, Robin was his adoring sister and he loved her, which meant he was willing to try and help Robin when she needed it. Little did he know that Robin's "formal attire" was anything but and her "interview" was unlike any normal job interview.
A few moments later, Robin's door opened back up as she walked out of her bedroom and back towards the living room where Robbie was, giving him the surprise of his life. Robin came back out of the bedroom wearing nothing but a semi-transparent bra and semi-transparent panties all while she showed them off to her brother in a playful way. "So...what do you think, do you like them?", she asked coyly as Robbie sat on the couch with his eyes wide open, stammering repeatedly as he was unsure of what to say in response to this sudden development. Eventually, Robbie was able to gather enough of his thoughts to form a sentence.
"Wh...what kind of job interview are you going to anyway?", he asked somewhat nervously as Robin continued to show off her attire to him.
"It's an audition to be a dancer at a strip club", she told him playfully as Robin came closer to the couch. "But that's not all I want to show you...I need the opinion of a male to determine just how sexy I am, and since you're the only one around...well, you know", Robin added as she approached Robbie as he continued to stammer nervously before she took a seat in his lap.
"Just relax sweetie and let me show you what I have to offer. Right now, don't think of me as your sister...think of me as any random plusle girl you'd meet at a strip club who wants to pleasure you", she added gently while Robbie looked into his littermate's eyes and gulped nervously. Part of him wanted to resist, but then again he did promise Robin he'd help her and his bond towards Robin overcame any doubts in his mind about whether or not he should let her do this.
Soon, Robbie felt Robin brushing her panty-covered crotch against his own, rubbing it against his pants while also pulling his face towards her bosom as Robbie felt the softness of his sister's breasts pushed against him. As he was in this situation, Robbie tried to think that Robin was someone else, but the fact that she was his sister still came through to him.
However, as Robin was continuing to rub against him, something clicked inside his mind. All of a sudden, Robbie got to thinking that while Robin was his twin sister, she was also a female and her touch was starting to affect his sexual desires. He had never had sex with a girl before and just to be in the arms of a female while she was being intimate with him was enough to get Robbie excited. As a result, his cock started to become erect, bulging into his pants as it started to rub back against Robin while she moved in his lap.
When Robin started to feel her brother's bulge against her panties, she giggled for a moment before moving against him faster, feeling the growing bulge in his pants pushing upwards as if it wanted to break free from them and enter her. "I see that you seem to like this", she commented softly while keeping her breasts pressed towards Robbie as he moved a bit so he could look towards her. "So...tell me, how sexy do you think I am?", she asked curiously as the bulge inside Robbie's pants grew stronger while pointing upwards toward Robin's panties, beginning to feel damp with precum as he was becoming aroused.
"You're...you're...beautiful...I can't help...feeling horny for you", Robbie answered as he stammered a bit while speaking, feeling the growing warmth of Robin's body touching his own while his shaft was now fully erect inside his pants and pointing almost straight up as it touched Robin's panties. "You make me feel like...I want to...have sex with you", Robbie continued while stammering, admitting freely that his sister's touching was making him crave direct sexual contact. By this time, he had completely blocked out the fact that she was his twin sister and concentrated more on the fact that she was a female and she was making him incredibly horny, as his erection clearly indicated.
As soon as Robin heard her brother's admission, she wasn't really surprised by his reaction as she could tell that his cock wanted to get inside her from the way it was poking up through his pants and pushing against her panties. Unlike Robbie, Robin seemed more receptive to the idea of having sex with her twin. Her love for him was strong and since he admitted he wanted to do her, Robin figured that she might want to try and ask him if he really wanted it. "Do you want to have sex with me...right now?", Robin asked curiously as Robbie looked into her eyes as his mind was clouded with the thoughts of finally placing his cock inside a warm vaginal canal.
In a high-pitched tone, he told her that he did want to have sex as Robin giggled before climbing up off of his lap. At that time, she took off her bra and panties, leaving her now completely nude as she turned back towards Robbie. "Alright, now it's your turn...take off your pants and boxers so I can see it and then ride it", Robin instructed her brother as Robbie did as he was asked, removing his pants first before dropping down his boxers. He didn't take either of them off completely as he was seated on the couch, he simply dropped them down past his knees.
Upon the removal of his boxers, Robbie's stiff, sky-blue boner was revealed, standing straight up at nearly 8" long with precum beading at the tip. "He certainly has a nice looking one", Robin thought to herself upon seeing Robbie's shaft. "If he feels as good as he looks, I might have to let him do me more after this", she added before coming back over towards the couch.
Robbie continued to sit on the couch as Robin re-joined him, now sitting in his lap with his boner straddled between her vaginal lips as she rubbed her bare pussy against his bare shaft. Robbie's cock throbbed with approval upon feeling Robin's vagina rubbing against the meat of his shaft as she teased it a little more to get him "just right". "Ah...it feels so warm...so wet...", Robbie commented on the feel of Robin's pussy touching him before she interrupted him.
"...and it's horny for you too", Robin added, finishing what Robbie had started as she rubbed her lips against the meat of his shaft while feeling her pussy reacting towards it. Robin could feel her vaginal walls beginning to contract and spasm a bit while she was warming him up, becoming hot and wet inside...making it nice and welcoming for her brother's shaft. She knew that he was still a virgin, and she wanted to make sure Robbie could enjoy his first time as much as possible.
While she was rubbing against him, Robin could feel Robbie's maleness throbbing very strongly while she also noticed that his cheeks were beginning to spark. She knew he loved how she felt against him, especially once she started to see the tip of his cock beginning to swell and spurt precum from the tip of it. That's when Robin knew that he was ready and that it was time for her to let him inside. "If you like how that feels, then you're going to love this", Robin commented playfully as she moved on top of his lap, lifting off of him for a second while she leaned down and pulled his shaft towards her, aiming the tip towards her vagina.
Slowly, Robin moved down towards Robbie as he sat there and watched his sister lower onto his pulsating and highly eager cock, launching more precum from the tip upward as it hit her vaginal lips, glazing them upon contact. Soon, those same vaginal lips touched the tip of his cock as he felt it push against Robin's vaginal opening while she lowered onto him. It stayed in that position for a few seconds before Robin sat down on his cock, feeling it move into her pussy while she lowered down onto him.
Upon feeling Robin's folds around his shaft, Robbie's cheeks started to sparkle with bolts of negatively charged electricity while his shaft throbbed and thickened inside his sister's warm and inviting vagina while her own charge gently buzzed through her lips and into his shaft...making his shaft spurt precum more rapidly and with stronger surges.
For the first time in his life, his cock was inside a warm vaginal canal, and he loved every second of being inside Robin as she lowered down onto him until she couldn't take anymore of his cock within her. In fact, the feeling was so good to Robbie that it made him want to cum inside her as quickly as possible as he promptly grabbed onto her buttocks and started thrusting upward rapidly.
However, before he could get totally into it, Robin put her hands on his chest and stopped him. "I know that it must feel really good for you to be inside me right now, but if you want to please the ladies, you'll have to learn to control your urges. It'll be better for them, and it will also be better for you", Robin explained to Robbie as she sat in his lap and on top of his throbbing cock while feeling precum hitting against her vaginal walls.
"Let me do the work for you this time so you can get used to how I feel and make it more worthwhile when you do cum in me", Robin added as Robbie looked to her and reluctantly nodded as he felt his balls were already wanting to be drained inside Robin's tight and electrically charged folds.
Once she had settled her brother down, Robin proceeded to start riding his cock, feeling it moving through her canal slowly as the thick shaft pulsated along the way. Unlike Robbie, Robin was sexually active and had taken several different cocks inside her canal before. However, out of all those, Robbie's seemed to be the thickest to her as well as the most responsive as it constantly throbbed and spewed precum into her unlike any of her other partners.
"Oh Robbie!", she cried excitedly as the thick maleness began to buzz with his negative charge all while Robin's folds buzzed with her positive charge. Naturally, the opposite charges attracted towards one another, creating a strong buzz of electricity between them while Robin rode her brother, allowing each of them to feel the energy of their sibling while also feeling their own pleasure. "Why haven't we done this sooner?", Robin wondered curiously to herself, thinking that the feel of their union was so strong and arousing that she would probably be open to the idea of having Robbie have sex with her regularly if he wanted to after this.
Meanwhile, Robbie continued to feel Robin moving up and down on his cock, feeling the swollen tip of his shaft pushing far into her tightness and then pull back out until most of it was back outside before taking it in again. This allowed Robbie to feel Robin's body rubbing against his shaft, massaging it vigorously as he finally gave in completely to Robin and let her ride on top of him. His shaft appreciated this and his balls were also enjoying the ride while they were beginning to churn with a batch of hot and sticky cum that he would soon be giving to her.
The slow ride helped Robbie relax and eased the fire inside his loins, keeping him from wanting to plow Robin as quickly as possible and spew his load within her all in a quick fling. Now, Robbie wanted to relax and feel the rubbing of her walls against his shaft while their combined electrical charges made both of them feel even more aroused than they would be normally.
As their electrical charges combined between them, Robbie continued to grow more aroused as his shaft was moving in and out of Robin's vagina. It became much thicker, filling her hole quite well while she held onto it as Robbie's shaft also started to twitch with strong pulsations. His precum continued to spurt from his tip, gradually becoming thicker and stickier with each successive shot, reaching up towards Robin's cervix while she felt it touch her insides.
Robin's hole started to rhythmically clamp down on Robbie's shaft near her opening each time she felt a fresh spurt of his precum hit inside her, helping to stimulate her brother as well as milk more of the juices from his tip. "Mmm...you're making a thick and creamy load for me inside your balls aren't you?", Robin thought eagerly as she could tell from past experiences with other males that Robbie was very aroused and the feel of her vagina was making him quite eager to fill her up. Although she wanted to continue as long as possible without setting him off, Robin also knew what would soon happen to her...knowing that his load would be very sticky and would cling to her insides like glue as it filled her, leaving it stuck within her body for several days thereafter.
She wanted to feel Robbie's cum inside her, to feel his seed stuck to her vaginal and uterine walls while his sperm tickled her insides as they tried to fertilize her eggs. Of course, precautions had been taken years ago to prevent this after an incident where Robin had close call when she was 13, nearly becoming pregnant at that age, so even if he did fill her and she did ovulate, his sperm and her eggs would not be able to meet.
While she continued riding him, Robin looked down towards Robbie as she saw his cheeks sparkle and his tongue hanging out of his mouth in delight. "Robbie...as soon as you feel close, put your hands on my hips and hold onto me tight. Then, I'll let you do the rest", Robin explained to her brother while she kept bouncing on his thick shaft, feeling the sky blue boner rubbing against her walls vigorously while she kept clamping down on it periodically.
By now, Robbie's balls had grown very heavy with a thick wad of sperm, feeling the tension of years of waiting to be drained inside a female nearing an end. The tightness of his sister's folds was milking his cock, rubbing it in all of the right places while he sat on the couch and let Robin ride on top of it. He had heard Robin's suggestion to him and intended on taking her advice as soon as he was ready. In the meantime though, he just relaxed and let Robin massage his shaft while he placed his hands on her bosom, groping at her breasts while they moved up and down with her.
However, it would not stay that way for long as Robbie felt his shaft becoming very sensitive as it was moving through his sister's pussy and he could feel the load within his balls getting ready to move. As Robin continued to ride him, Robbie slowly traced his hands down the sides of her body as his climax neared, feeling his shaft rubbing against her walls as it twitched even more within her. He moved his hands down her body until he reached her hips, placing his hands on them and holding on tight.
At that moment, Robin immediately sat down on his shaft, allowing it to push as far as it would reach into her before looking down towards her brother. "Now it's your turn", she told him playfully...giving Robbie his chance to lead and deliver his cream to her waiting vagina.
Robbie immediately seized his chance and started to thrust rapidly upward into Robin, feeling his shaft eagerly move in and out of her as he drove it home while the tightness of her walls was making him want to fill her even more. Strong bursts of precum now launched from his tip as a precursor to his orgasm, flying up into Robin's now-open cervix and reaching into her passage. The feel of his rapid and eager thrusting was making Robin very happy as her own body was reacting to her brother's eager cock. Her own cheeks were sparking as much as his were now as bolts of red lightning were coming from hers while bolts of light blue electricity eminated from Robbie's.
The feel of his precum hitting her cervix was more than enough to get her reproductive drive in gear as within a few moments of feeling her brother drilling her pussy, she could sense that her ovaries were releasing eggs into her fallopian tubes...several of them as her body temperature and electrical charge spiked each time she ovulated. In all, she must've figured that she released at least a dozen eggs from her ovaries. "It's a good thing that I have my tubes blocked off right now", she thought to herself, knowing that if it wasn't for that, she would surely become pregnant from Robbie.
As Robin was ovulating, Robbie could feel the spikes in her vaginal temperature as well as the increase in her charge and knew instinctively what was happening to her. By now, he had gotten into his sister so much that he completely blocked out the fact that he was having sex with his twin. Right now, all he thought about was being inside the warm vagina of a receptive female and allowing his instincts to take over him and follow through with his own biological urges. He thrusted upward as deep as he could go and then released his tensions within her.
A thick and intense blast of cum rocketed upward from Robbie's shaft, surging through Robin's vagina and open cervix as some of it coated her vaginal walls while more of it passed through the cervix and began to pool in her womb. Upon feeling his load beginning to coat her insides, Robin's vaginal walls immediately clamped down on his entire cock as hard as she could and began to pull on it, helping Robbie shoot as much of his load into her as possible while she could also feel the massive pulsations in his shaft each time a fresh burst of his seed was sent flying into her.
Both of the siblings were feeling very happy with their union with Robbie proudly sending cum into Robin's welcoming vagina while she took his load and felt the incredibly sticky and sperm-laden cream against her uterine walls, tickling her insides as they tried in vain to meet up with her cluster of eggs that were trapped inside her fallopian tubes, unable to get out. As she was being filled, Robin leaned down over Robbie as their cheeks continued to spark with electricity, now meeting as they came close to one another with their combined charges creating a bolt of white lightning that connected each of them to each other.
With the strong buzz of their combined charge in her cheeks and warm cum shooting upward into her reproductive tract, Robin felt very happy with what Robbie was giving her and placed a kiss on his lips briefly, showing that her feelings towards him were now stronger than they were before.
Robbie intense climax lasted about a full minute as he drained his swollen and happy balls into Robin, creating a large pool of cum inside her uterus while her entire cervix was filled with it as well. The cream in her cervix would soon thicken and harden into a plug, keeping his sperm inside Robin's womb while keeping other males out of her until she was pregnant...or that would be the case if her tubes had not been blocked off. However, Robin had no desire to seek other males right now, she was quite happy to keep her brother's cum inside her and didn't want to have sex with any other male in the near future.
Gradually, both Robin and Robbie began to settle down as his orgasm came to an end while she relaxed her grip on his cock as it was calming down. Slowly, the sky blue cock was beginning to exit Robin's vagina as they both relaxed after sex together, both of them feeling the tingle of their afterglow over their entire bodies as they each felt happy to have had sex together.
When Robbie's shaft finally came free from Robin, leaving behind a small creampie as it did so, seeing as most of his load was deep inside her and could not escape, Robin gave Robbie another kiss on his nose as she sat on his crotch a little longer while feeling his shaft returning to its sheath. "So...do you feel better now?", she asked him sweetly, wondering if putting his cock into her helped eased Robbie's tension about finding a job.
With a happy smile on his face and his eyes closed, Robin's words rang in his ears happily as he felt the afterglow of sex throughout his body. "I can't believe I came inside my sister", he thought to himself as he sat there as the instinctive feeling he had been feeling was starting to fade while his normal thinking was beginning to take control again. However, after a few seconds, that thought really hit home to Robbie as his eyes suddenly burst wide open and a sense of dread filled him.
"OH MY GOD...WHAT HAVE I DONE?!! I JUST FILLED MY FERTILE SISTER'S WOMB WITH MY SEED!!!", he exclaimed as he felt extremely nervous with Robin still on top of him, hearing his comments as she placed her hands on his cheeks to try and calm him down. "Mom and Dad are going to kill me when they find out I knocked up my own sister!", he added hysterically while Robin continued to try and ease Robbie's sudden tension.
"It's alright...I'm not going to get pregnant", Robin told Robbie softly as her hands rubbed against his cheeks while she stayed with him. "Settle down Robbie...everything is going to be OK", she added as Robbie didn't seem to respond to her first request as he looked towards her while sweating nervously.
"But...I felt your temperature spike several times right before I came in you. Every male knows when they feel a female's temperature spike during sex that means they're ovulating", Robbie answered while still feeling nervous about what he had just done. "Are you saying that you didn't ovulate during sex?", he asked curiously as Robin smiled.
"No...I did release eggs during sex with you...quite a few of them in fact", Robin answered as Robbie's face turned white for a moment as he became even more panicky. "But...my eggs won't get the chance to be fertilized by your sperm", Robin added as Robbie's ears perked up as he looked towards her again.
"What do you mean...if I came inside of you and you ovulated during sex, doesn't that mean that you'll become pregnant?", Robbie asked Robin as she placed a finger on his nose and giggled.
"Silly boy...don't you remember what happened to me when I was 13 and what Mom and Dad made me do before I could even think about having sex again?", Robin told her brother as Robbie thought about that and suddenly remembered the conversation that their parents had after Robin's pregnancy scare a few years earlier, making her have the surgical procedure to have plugs placed inside her uterus for each of her fallopian tubes. At that time, Robin didn't want to have it done, but the plugs could be removed if she wanted to actually have a family of her own and the plugs did give her sexual freedom to go all the way with the boys without worry about pregnancy.
The instant Robbie remembered the plugs, he immediately relaxed. "Thank god for that...for a second there, I thought that we were going to get in trouble", Robbie exclaimed as he calmed down. "Although, when I felt you ovulate, something came over me that drove me to want and fill you up anyway", Robbie added as Robin moved in closer to her twin.
"That's because you were following your instincts...your cock didn't know that it was inside me, it was just doing what it does naturally. When it felt my body become receptive, it tried to conceive life within my womb, just as it would do with any female you were to put it in", Robin mentioned before giving Robbie a kiss on his nose.
"Though I have to admit, I enjoyed having you try to impregnate me...I got a lot of warm and sticky cum out of you and now that my cervix is going to be plugged, it'll stay inside me for a few days", Robin added. "Tell me something Robbie...if I wasn't your sister, do you think that you'd want to be my boyfriend, because when I felt you cum inside me...I had feelings for you like I never felt before", Robin continued as Robbie looked his sister in the eyes and smiled.
"I know exactly how you feel...for some reason, it felt as if I was meant to be together with you this way", Robbie answered as he looked to Robin excitedly and placed his hands down around her hips again, holding them softly as he leaned towards her and kissed her nose. "Do you think that we were meant to be more than brother and sister?", Robbie asked Robin as she smiled and kissed him again, this time on his lips.
"Does that answer your question Robbie? When you came in me, I knew I had to have you as my lover to feel your cock in me as often as we desired. Of course, we can't have a real relationship together like other couples...but that doesn't mean we can't still love each other and express our love through sex...but I'll leave that up to you to decide", Robin explained as she moved in close to Robbie again with her nose touching his while her hands were on his cheeks. "So...tell me Robbie, how do you see me? Do you see me as your twin sister...or as your sister and lover?", Robin asked softly as Robbie sat there with Robin in his lap waiting for his answer.
He looked deep into her eyes, thinking about her words as he saw visions of sex between them in his eyes while hearing the echoes of their voices as they were delighted by their union in his ears. With Robin, Robbie was guaranteed to have a female to both love him and who was willing to have sex with him, even if he couldn't find a date of his own. Of course, Robbie also knew that he'd eventually have to find a female outside of Robin to marry and have a family with...but this wouldn't be for a while yet and even after he did find the right female, he'd still want to be able to have sex with Robin every once in a while.
For now though, the warmth and tightness of her pussy had pleased him and taken his virginity and there was no way he wanted to give that up...especially with a willing partner in front of him. "Both", Robbie answered playfully as Robin smiled and put her lips upon Robbie's as they kissed happily. During their kiss, their electrical charges intermingled again, creating a white bolt of lightning that connected the two of them to each other. From that moment on, it was quite clear that Robbie and Robin no longer had a simple brother/sister relationship, they were now something more than that.
That night, the two siblings shared the same bed together for the first time since they were little...this time completely nude with Robbie laying next to Robin as he was behind her. His hands grasped her body softly while he rubbed up against her in his sleep, his sky blue cock brushing against her butt cheeks while precum spurted from the tip. Robin smiled as she felt Robbie humping her in their sleep, thinking about how it felt to have his cock in her earlier and about all the times she hoped to take it within her again for as long as they could remain together.
The End
