The Wager
TW: Incest
It was the first day after high school graduation, and Jae was going to enjoy the next five days of leisure. The following Monday afternoon he would have to start his new job at the local cheese processing plant. His parents, who are day shift supervisors, arranged for him to be hired once he graduated.
Jae had wanted to go to college, but he couldn't maintain high grades. It wasn't that he was unintelligent. The young man just hated studying. So, he was stuck doing manual labor until something better came along.
At 6'2" and a hundred ninety-five pounds, Jae is a good-looking young man. He has wavy brown hair and a strong jaw line that has always attracted girls.
Xinyu, his girlfriend, is so smitten by Jae that after they turned eighteen, she started letting him have semi-protected sex with her regularly. She would rather that he use condoms, but his extra-large cock sometimes caused the condoms to tear during sex. So, she would take her chances and hope that the birth control cream keeps her safe from pregnancy. She also makes Jae pull out before he can fill her pussy with his cum.
His oversized cock also caused problems when they first started having sex.
When Xinyu first saw the monster, she wanted to back out.
However, Jae got his girlfriend to agree to try by allowing her to be on top so that she could control the pace of their lovemaking.
It was a slow process at first.
Xinyu had to rub her boyfriend's cock head across the entrance of her cunt for nearly ten minutes before she finally got the courage to lower her pussy onto the monster.
When the thick head finally did penetrate her tight hole, the girl felt like a sausage was being stuffed inside her. The twinge of pain from her hymen tearing caused her to whimper.
Xinyu was determined, though. She loved Jae and wasn't going to let something like his size stop her from giving him what he wanted.
It took quite some time, but once Jae's cock had filled Xinyu's stretched pussy, she gazed at her lover with a look of pride.
"We did it," she beamed. "I got all of you inside me."
They went slow the first few times they made love.
The third time they had sex, Jae exploded into his girlfriend's body.
Xinyu wasn't sure, but something didn't feel right. She eased Jae's dick out of her cunt, only to discover that the pre-lubricated condom had broken.
She freaked out, believing that he'd just impregnated her. Fortunately, her fears were alleviated when she started her period the following week. After that, she started using birth control cream as well as making Jae wear pre-lubricated condoms.
When another condom broke a few weeks later, Xinyu decided she didn't want to end up with small pieces of latex inside her, so she started letting Jae fuck her bareback, with only the birth control cream for protection. She would make him pull out before ejaculating.
Yooyeon, at nineteen, is a year older than her Brother. She is a well-endowed young woman who gets lots of attention from the local men. Her face is a little broad, yet for some reason that odd feature makes her even more attractive. Yooyeon has shoulder-length brown hair and an infectious smile. She is a daredevil. One of her favorite hobbies is gambling. Yooyeon will make a bet on just about anything.
Yooyeon also works at the cheese processing plant. She works the second shift, the shift Jae would soon be working, while her parents work the first shift.
As Jae began to wake up, he kicked off the covers and stretched. Jae had slept in the nude for as long as he could remember. His usual morning erection was standing almost straight up. As the cobwebs began to clear out of his head, the young man reached down and absently stroked his massive cock, like he usually did.
Yooyeon, who had gotten home sometime after midnight the night before, was also waking up. She was wearing a wife-beater T-shirt and a pair of cotton panties. As she sat up and rubbed the sleep out of her eyes, she remembered that the second shift supervisor had told her to have Jae come in to fill out his safety forms.
"Just have your Brother follow you to work," Yooyeon's supervisor had told her. "You can show him to my office before starting your shift."
Yooyeon stretched and stood up. "I guess I'd better let Jae know what's going on before he takes off for the day." She didn't bother to dress, since Jae had seen her in her sleeping clothes numerous times. She left her room and crossed the hall to her younger Brother's door. Still half asleep, she opened the door without thinking to knock.
Jae was still lying on his bed, stroking his morning erection when his older Sister walked in.
"Mike, the second shift supervisor wants…" Yooyeon stopped dead in her tracks. All remnants of sleep instantly disappeared. "What the fuck?"
"Don't you know how to knock?" Jae exclaimed.
"I'm sorry, I just wanted to tell you that Nick wants you to come in this afternoon to fill out some forms and go over safety protocols with him." Yooyeon couldn't take her eyes off her younger Brother's cock.
Jae couldn't help but notice that his Sister was staring. "Haven't you ever seen an erect cock before?"
She shook her head. "Not a cock that big, I haven't. That thing is huge."
Jae shrugged as he continued stroking his dick. "Yeah, I know, my dick is kind of big."
"Kind of big, are you kidding me? You put a horse to shame." Yooyeon tried to tear her eyes away, but she couldn't stop staring at her Brother's massive cock. How the hell do you get that thing inside Xinyu?" She asked.
Jae squeezed his monster. "I just take my time. The first few times, I had to go slow with her. But after a while, her pussy stretched enough so that it slides in a little easier each time we fuck. Now, she can take it easily."
Yooyeon stared at the monster. "That thing fits inside her pussy?"
"Yeah, we fuck once or twice a week. We started fucking a few months ago, after we both turned eighteen."
Yooyeon shook her head in disbelief. "Xinyu has got to be walking bowlegged by now."
"Nah, a lot of girls can take something this size."
Yooyeon snorted. "You're dreaming, little Brother. That thing would split most women's pussies wide open. The head is bigger than my fist. Your dick has got to be at least a foot long."
"A newborn baby is bigger around than my cock, and yet women deliver babies all the time."
"Yes, but they endure hours of agony delivering those babies. I can't see you waiting that long. You probably want to shove it in as quickly as you can."
Jae chuckled. "I've had to learn to be patient. I let Xinyu get on top when we first started having sex. She would slowly lower herself onto my cock, taking it in as her pussy adjusted to its size. Once she got adjusted to having my cock in her, I'd roll her over on her back and fuck her missionary style. She has the best orgasms when we fuck." As Jae explained how he fucked his girlfriend, he noticed that his older Sister never took her eyes off his dick. The desire to fuck his older Sister once again roared to life. Jae had wanted to fuck Yooyeon for as long as he could remember. As he looked his scantily clad Sister over a devious thought ran through his mind. "I'll bet if you went slowly at first, you could take a cock this big inside your pussy."
"Oh hell no," Yooyeon shot back. "If I tried to ride a dick that big it would rip me open. Something that thick would never go inside me in the first place."
Knowing Yooyeon's love of gambling, plus her desire to rent a place of her own, Jae made his move. "I'll bet you a hundred bucks that you could take one that big."
"You want to bet me a hundred bucks?" Her gambling bug instantly kicked in. Yooyeon saw a great opportunity to win an easy bet. "Wait a minute, where are we going to find a dick that big to make the bet with?" Yooyeon asked.
Jae smiled at his Sister. "In order to know that you actually tried, I'd have to witness the attempt. So, I guess we'd have to use my dick for the wager."
Yooyeon's gaze left her Brother's dick for the first time. She stared at Jae in disbelief. "There is no way in hell I'm letting you fuck me. That would be a little too weird."
"I didn't say I was going to fuck you Sis. I just said I'd let you try to get my cock in you for the bet. Once you tried, and succeeded, or failed, we'd stop, and one of us would pay up."
Yooyeon was torn between the strangeness of doing this and her desire to win a bet. "I don't know. I wouldn't want something that big inside me. Besides, you don't have a hundred dollars. How do you intend to pay up when you lose?"
"Simple, I'll double the bet if I lose. If you can't get my cock inside you after fifteen minutes, I will pay you two hundred dollars after I get my first paycheck."
"I don't think it would be a good idea for us to be trying this. The idea of having my Brother's dick head at the entrance to my pussy is disgusting."
"You've done more disgusting things than this to win a bet. Remember the time you swallowed six night crawlers to win three hundred dollars?"
Yooyeon knew Jae was right. She had done some pretty bizarre things in the name of gambling. Once she streaked around the outside of her house in the middle of the afternoon to win fifty bucks from her younger Brother.
Fortunately her Parents were at work, and no one saw her but Jae.
Her gaze returned to her Brother's erection. She knew that all she'd have to do is make a half hearted attempt for fifteen minutes, and she'd win the bet. With the extra two hundred dollars, she could finally afford the deposit on an apartment, and then she could move out. "Ok, it's a bet. I try for fifteen minutes to get that thing inside. When I win, you pay me two hundred dollars after you get your first paycheck." Deciding to make the bet more difficult for Jae to win, she added, "However, your cock has to go all the way in until it reaches my cervix."
"In that case, you have to try for twenty minutes."
Yooyeon let out a small laugh. "Sure, why not?" Yooyeon knew that if that thing wasn't going to penetrate her in fifteen minuets, an extra five minutes wouldn't make a bit of difference. "It's a bet. However, you can't tell anyone about this."
"I won't say a word, I promise." Jae knew his Sister would only try hard enough to make it look good, but the young man had a plan. He opened the drawer to his nightstand, and pulled out a tube of KY jelly.
"What's that for?" Yooyeon asked suspiciously.
"If you're going to be rubbing your pussy lips on my cock head for twenty minutes, I want some lubrication. I don't want you rubbing me raw."
"Just use a condom."
Jae shook his head. "That would add extra thickness to my cock. It would give you an unfair advantage. Besides, I haven't found any condoms that fit properly. They occasionally break when Xinyu and I are having sex. Xinyu is afraid of having pieces of condom left in her, so I always pull out before cumming when I fuck her. Plus she uses birth control cream to diminish the chances of pregnancy."
"I can't use birth control cream. It makes me itch. And there is no way you're putting your bare dick against the entrance to my pussy. If you came with your cock head shoved against the entrance, your sperm would shoot inside me, and I could end up pregnant. There's no way in hell I'm letting anyone, especially my little Brother knock me up."
Jae stared at his Sister in surprise. "Aren't you on the pill?"
"I keep meaning to get a prescription, but doctors cost money. Besides, I usually make guys wear condoms."
"Hell, you have nothing to worry about anyway. I'm not going to cum in you. I have very good self control. With a dick is as big as mine, I had to learn self control. Otherwise I'd have ejaculated long before I got my cock inside Xinyu. Besides, we're not going to have sex. We're just having a friendly wager."
Yooyeon thought about the statement for a few moments. "Yeah, I guess you would have to learn to wait before cumming. And like you said, we're not going to fuck. So, how do we do this?"
"I'll lie on my back, and you straddle me. I'll hold onto your hips, to help you keep your balance, and you ease the head of my dick against the entrance to your pussy. You then let a little weight down so that the head presses against the entrance to your cunt. You then rock back and forth a little to keep your pussy moist. As your pussy walls open up, you ease down a little farter until my cock completely fills you. Once the tip of my cock touches your cervix, you take my cock out, and I win the bet."
"Or, the thing never goes in, and I win the bet," Yooyeon replied. Feeling excited about the two hundred dollars she was about to win, Yooyeon stripped off her panties.
Jae opened the KY jelly and rubbed a liberal amount on his dick head, and along his shaft.
Yooyeon approached the bed, and waited for her Brother to finish lubing up. She smiled inwardly, knowing that soon she would win two hundred dollars and have a place of her own.
Jae replaced the cap, placed the lube back on his nightstand, and then laid back. "Ok, climb on."
Yooyeon climbed onto the bed, and then straddled her Brother. She grasped his shaft and lined it up with the entrance to her cunt. She felt strange holding her Brother's cock head against the entrance to her cunt, but a bet is a bet; and Yooyeon intended to win.
His dick was so long that she didn't have to lower her hips very far for it to touch the entrance to her pussy.
"Get ready to lose two hundred dollars, little Brother. There is no way this thing will ever get past the entrance, much less go completely inside me."
Jae didn't say a word. He knew from experience with Xinyu that Yooyeon's pussy would stretch to accommodate the thickness of his cock. The head of his cock would be in his Sister before she even realized what had happened. Once he got past the entrance, there would be no stopping him. He'd fuck his Sister until she screamed.
Grasping Yooyeon's hips, he gave her a small nod. "Check the clock to see when we begin."
Yooyeon checked the clock on the nightstand. "It's nine thirty five. At nine fifty five we stop." She began rubbing her Brother's cock head back and forth across the entrance to her cunt. As she rubbed his manhood through her vaginal lips, and across her fuck hole, Jae applied gentle pressure to her hips.
"Don't try forcing me down," Yooyeon warned. "If you force that thing in me, it'll be cheating. Plus you'll hurt me."
"I'm not going to force my dick into you. I just want to make sure you don't cheat. If my cock starts going in, you have to let it. You can't hold back, or you forfeit the bet, and pay up."
Yooyeon kept rubbing the head of her Brother's dick across her entrance. With each pass she'd rub the tip against her clit.
Jae held firmly to his Sister's hips, making sure she kept enough pressure to cause penetration once her vagina opened up enough to accept his cock head.
After several minutes of rubbing Jae's cock head across her clit, Yooyeon's body began to respond to the stimulation. Her clit became inflamed, and her vaginal opening began to expand. Her pussy was getting ready to be fucked.
Yooyeon glanced at the clock. A smile appeared on her face.
Seven minutes had passed, and he hadn't penetrated her yet.
"I am so looking forward to winning this bet." She continued to rub his tip along her slit.
Jae felt the tip of his cock penetrating the entrance to his Sister's pussy as she rubbed it through the fold of her labia. He smiled inwardly knowing her cunt was ready for penetration. "Ok sis, you need to stop rubbing, and rest some of your weight onto my cock to see if it will go inside."
Yooyeon swallowed hard. She didn't believe the thing would go inside, but she was still a little nervous. Taking a breath, she allowed some of her weight to rest on her Brother's cock head.
Part of Jae's cock head slid inside his Sister's pussy.
Yooyeon gasped involuntarily. Her body shuddered, as the monster spread the entrance to her cunt open. She tried to rise back up, but her Brother held her in place.
"Hold still," Jae instructed his Sister. "Let your pussy get used to being penetrated."
For the first time, the pretty nineteen year old began to suspect that she might lose the bet. "Fuck," she seethed under her breath. Yooyeon was sure that because it was her Brother trying to penetrate her pussy, she would stay dry enough to prevent him from entering her cunt.
However, between the KY jelly, and the stimulation of her clit; her pussy did what came naturally, and opened up. Her body didn't care who was trying to fuck her. Her cunt was doing what it was designed to do.
Yooyeon felt the monstrous head spreading her open. She shuddered again as pussy walls spread further.
"Let your body lower a little more," Jae said.
Yooyeon closed her eyes, and gritted her teeth. She didn't want to follow her Brother's instructions, but she had agreed to the bet. Yooyeon let her knees bend a little more so that she would sink lower.
The rest of Jae's cock head slid into his Sister's cunt.
Yooyeon felt her vaginal walls stretch as her Brother's cock head sank deeper into her body. She wasn't in pain, but she could definitely feel her vaginal walls stretching. "Maybe we should call this bet off," Yooyeon said weakly. She knew her Brother would never agree to it, but she had to try.
Jae shook his head. "A bet is a bet. You're not trying to welsh on a bet are you?"
Yooyeon gave her Brother a glare of disdain. "Your cock hasn't reached my cervix yet, little Brother. This bet is far from over."
Jae gripped his Sister's hips tightly. He slowly began lifting her up off his cock until only the tip was inside her.
Yooyeon thought that perhaps Jae was letting her off the hook.
He then lowered her hips back down, causing her pussy to open up more.
Yooyeon whimpered as another inch of his thick monster sank into her body. She shuddered as her Brother's cock stretched her inner walls. Yooyeon knew she was going to lose the bet.
Now that Jae's cock head was inside her, it wouldn't take him long to sink all the way into her cunt.
"Fuck, it's too big," she pleaded, hoping he'd have mercy on her and quit. "Jae, you'll rip me apart."
"Don't worry Sis, I'll go slowly. Your pussy will stretch. And I won't force it in. We'll go only as fast as your body can handle." He gave his older Sister a devilish smile. "Look at it this way. At least you'll get the satisfaction of knowing you can take a big cock inside you."
"Yeah, but it's your big cock that's in me. This is incest."
"Nope, it's a bet. I told you I wouldn't fuck you, and I meant it. Once my cock touches your cervix, we can stop."
Yooyeon desperately hoped that her Brother's cock wouldn't go all the way to her cervix, but deep down she knew better. She was about to lose one hundred bucks to her younger Brother. She was also about to have her younger Brother's huge cock buried in her stretched out pussy. "You promise we'll stop as soon as your dick is all the way inside me."
"I told you this is just a bet. I'm not going to fuck you." Jae was lying, but he knew that once his cock was all the way inside her pussy, Yooyeon wouldn't want to take it out. Having her pussy stuffed to the limit would drive her into a heightened state of sexual arousal.
Her Brother's words encouraged Yooyeon to get it over with. "I still have a chance of winning. Getting that thing in the entrance is one thing. But taking it all the way inside me is entirely different." Yooyeon knew her only hope was to cheat. She'd pretend to try, but not let it go any deeper.
Jae knew what she'd try. He had no intention of letting her succeed.
Yooyeon lifted her hips. She then gently eased her pussy onto her Brother's throbbing cock again, taking another two inches into her body. She had tried to hold back, but Jae's powerful hands applied just enough pressure to her hips to make his cock sink deeper into his Sister's cunt. Yooyeon's pussy was going to have that cock no matter how much she protested. Yooyeon mewed as her Brother's cock sank deeper into her body. The sensation of having her vaginal walls stretched caused the young woman to tremble involuntarily. Her entire body shook as Jae's cock stretched her open even more. Yooyeon couldn't believe that Jae's huge dick might actually go all the way to her cervix.
Jae watched his Sister's expression as she eased herself onto his cock. He'd seen that look on Xinyu's face.
Yooyeon lifted her hips again, and then lowered her body onto the monstrous dick.
Once again, Jae applied gentle pressure to Yooyeon's shapely hips. His cock sank even deeper into Yooyeon's stretched out pussy.
"Jae, you're forcing me down on your cock," Yooyeon half heartedly protested. She knew he was just making sure she didn't cheat, but she had to try something.
"I'm being gentle. I'm just making sure you don't try to cheat."
Yooyeon let out a sigh. She wasn't going to be able to cheat.
Jae was making sure she stayed honest.
Checking the clock again, Yooyeon felt her heart sink.
Only ten minutes had passed, and her Brother's cock was already deeper than she'd ever thought possible.
Yooyeon began to accept the fact that she was losing the bet. To make matters worse, whether she wanted to or not, the woman was starting to get turned on. Without meaning to she sank even deeper onto the shaft. Her subconscious mind was starting to override her conscious decisions.
"Oh shit, I've never felt this full before," the pretty brunette moaned as her pussy accepted more of her Brother's huge cock. "Your dick is huge."
"You're going to feel even fuller before we're done." Jae reached around and squeezed his Sister's ass cheeks.
Yooyeon wanted to tell her Brother not to play with her ass, but the sensation of having her pussy stretched felt too damned good. She lifted her hips again, and sank back down on his cock. She tried hard not to take the monster deeper into her, but her body betrayed her. No matter how hard she tried to resist, she couldn't help but sink that monster deeper inside her cunt with each downward thrust.
More of Jae's cock invaded her pussy.
Yooyeon involuntarily moaned as intense pleasure shot through her nether region. She couldn't believe that having her Brother's cock inside her could feel so damn good. Her body began to spasm as a mini-orgasm abruptly shot through her loins. She sank deeper onto her Brother's cock. Nearly three quarters of her pussy was stuffed with her Brother's man meat. "Shit, I can't hold myself up any longer. Roll me onto my back before I collapse."
Jae drew his Sister down onto his chest, and then rolled his body onto hers. His dick sank deeper into her body. He was very close to touching her cervix. He rose up so that he rested his weight on his elbows.
Yooyeon looked down between their bodies. Her expression of shock was written all over her face. She could see a visible bulge in her tummy where Jae's cock was pushing against her belly. She began to ask herself just how much more of his dick would fit inside her before it reached the back of her birth canal.
Jae was glad Yooyeon had given him control. Now he could control how long it would take for him to completely fill her hungry cunt. "Are you ready to continue?" He asked.
Yooyeon looked up at her Brother, and quickly nodded yes. She then looked back down at her stomach.
Jae withdrew his cock and then sank back into his Sister's body.
Yooyeon watched her tummy return to normal, and then expand again as her Brother sank back inside her. She could feel his cock rubbing against that special spot just inside the entrance to her vagina. She whimpered yet again as he sank back inside to where it was before.
However, he didn't go any deeper. He simply withdrew his cock and plunged back into her again.
She shook as a second small orgasm hit her. She was amazed that her Brother had already made her cum twice, and he wasn't completely inside her yet.
Jae continued fucking his Sister, allowing his cock to sink in almost all the way before withdrawing.
It didn't take Yooyeon long to figure out that Jae wasn't trying to go deeper.
He wasn't trying to win a bet. He was fucking her.
"Jae," she gasped lustfully. "You're not trying to win the bet. You're fucking me."
He gave his older Sister a devilish grin, and continued to rock in and out of her. "Yes I am."
Yooyeon felt torn with what was happening to her. She knew she shouldn't let her Brother fuck her, but his huge cock was driving her wild with lust.
Jae knew he'd won. Not only was he going to win the bet, but his Sister was surrendering to her need to be fucked.
She took her eyes off her expanding and contracting stomach to gaze up at her Brother. Giving him a pleading look, she whispered. "Please, I want to feel your cock go all the way inside me. I know this is no longer about the bet, and we are fucking, but I don't care. Sink that monster completely inside my pussy."
Giving his older Sister a sly smile, Jae withdrew almost all the shaft of his cock, and then plunged deep into her body.
Yooyeon squealed as the last two inches of her pussy opened up to receive her Brother's monstrous cock. She wrapped her arms around his neck; and at the same time slung her long legs around his hips, as his cock tip pressed against her cervix. She bit her Brother's shoulder hard enough to leave teeth marks.
Jae groaned with pleasure as his Sister bit him.
"So deep," she moaned. "Your cock is so fucking deep in me. Damn, I feel completely stuffed." She gazed up at her sibling. Tears of joy were running down her cheeks. "You didn't split me open after all."
Jae leaned over and kissed Yooyeon. He pressed his lips against her mouth and slid his tongue against her lips.
Not caring that he was her Brother, Yooyeon opened her mouth.
Jae's tongue entered her open mouth. He began caressing her inner mouth with his tongue as he rammed his cock into her over and over.
Yooyeon's tongue danced with her Brother's as they fucked. All thought of bets, and having a place of her own flew from her mind. She was being fucked like never before. Yooyeon didn't want to stop. She didn't want Jae to pull out. She wanted to be fucked by her Brother.
Jae broke the kiss. He then licked away her tears. Jae grabbed the hem of his Sister's shirt and tugged.
Yooyeon lifted her upper body off the mattress so her Brother could finish undressing her.
Jae pulled the shirt off, and threw it onto the floor. He immediately lowered his lips to her left nipple and gently bit down.
Yooyeon whimpered as her Brother began to nibble and suck on her nipple. She thrust her hips against him to encourage him to continue fucking her.
Jae released the tender nipple, and began thrusting into his Sister again.
Yooyeon held her Brother's head in her hands. "Fuck, little Brother, your cock feels incredible. Fuck your big Sister hard. Make your Sister cum."
Jae felt his balls begin to churn. He knew he wouldn't last much longer. He began to furiously pound his Sister's stretched out cunt.
Yooyeon felt her body coiling like a spring. She was about to cum. Her wonderful Brother was going to make her cum like never before.
Jae pounded away at Yooyeon's pussy. He thrust into her repeatedly. His cock grew even thicker, stretching her pussy wide. Then just before he released his life giving sperm, he felt his balls touch his Sister's ass cheeks.
Yooyeon's pussy had lengthened another inch to receive his entire cock inside her. She screamed, as her body gave into the need to cum. She tightly gripped his neck, and screamed. The walls of her pussy clamped down on her Brother's cock, and began milking him for the sperm her body craved. Yooyeon's long legs held tightly onto her Brother as she came.
Jae bit his Sister's throat as he erupted deep inside his Sister's body. He began firing load after load of baby making sperm into her cunt.
Yooyeon pulled her Brother's face to hers, and began chewing on her Brother's lower lip. Her body shook with lust as she experienced the most intense orgasm of her life.
Jae went rigid as his balls continued to empty his baby making seed into his Sister's fertile womb.
Yooyeon held onto her Brother's face as tightly as she could as her body shook from her intense orgasm. Her long legs tightened around his hips, holding him in place. The pretty brunette shook, and writhed beneath her Brother.
As the siblings began to come down from their sexual high, the realization that they'd fucked bareback began to creep into their minds.
They broke the kiss and stared at one another in shock.
"Fuck, I just came in you." Jae stared at his Sister.
"What if you got me pregnant?" Yooyeon screeched. "I can't have my own Brother knocking me up. What would Mom and Dad say? Hell, what would my friends and co-workers say?"
Jae took a deep breath, and struggled to keep his cool. "Let's not panic yet. Just because I came in you doesn't mean you're going to get pregnant."
"Yes, but what if you did get me pregnant? I could end up having your baby. Shit, why did I agree to this stupid bet? Jae, you may have just knocked me up."
"Look, there's nothing we can do about it now. We'll just have to wait and see. People fuck all the time without conceiving children. The odds are really good that you won't get pregnant."
"I hope you're right. I love you baby Brother, but I don't want to have your kid." She ran her hand along her Brother's cheek. "However, I've got to be honest with you. I did enjoy having sex with you. I've never had multiple orgasms before. You made me cum three times. I don't think I'd be happy if this turned out to be a one time fuck."
"Does this mean you want to have sex with me again?"
"Hell yes. I want to fuck you all day every day while our parents are at work. But from now on you pull out before you cum. And I'm making a doctor's appointment. If you're going to keep fucking me like this, I need to go on the pill."
Jae leaned over his Sister and kissed her. He then gave her a warm smile. "You can forget about paying up on our bet. I got something much better out of it anyway."
Yooyeon squeezed Jae's softening cock with her vaginal walls. She felt her Brother's cock begin to stiffen. "I think you're about to get another payment on our bet. Just make sure you pull out before you cum this time."
Jae and Yooyeon fucked all day long, until it was time for Yooyeon to get ready for work.
Jae pulled out each time before spilling his seed where it didn't belong.
However, the siblings didn't think about the fact that pre-cum could also impregnate a woman.
Each time Jae fucked his Sister bareback, they increased their chances of making a baby together.
Later in the day, Yooyeon made an appointment with her gynecologist.
The soonest appointment available was three weeks away.
Yooyeon didn't want to wait that long, but she had no choice.
Jae would just have to pull out before he came for the next two weeks.
Yooyeon knew it was a dangerous plan, but she didn't want to wait two weeks before they resumed having sex.
Birth control cream was out of the question, because Yooyeon had suffered an allergic reaction to the cream when she tried to use it in the past.
She considered having Jae use a condom anyway, but the fact that the size of his cock would cause them to tear worried her. Trusting in a piece of latex that might or might not protect her was worse than having Jae pull out.
Jae's horror story about having left over pieces of latex stuck in her pussy worried Yooyeon.
Besides, Yooyeon loved the feel of her Brother's bare cock in her stretched out pussy.
Yooyeon got dressed for work, and then headed out the door, with her Brother in tow.
Jae followed his Sister to the plant in his pickup.
Yooyeon took Jae to meet their supervisor. She then headed to her station.
Jae filled out his paperwork, listened to the safety speech, and then headed home.
His parents asked him how the paperwork went.
The young man struggled to keep his voice from wavering as he spoke to his parents.
The memory of fucking his sexy Sister wouldn't go away. He was looking forward to the next day when his parents returned to work.
Yooyeon put in her shift, and then headed to the house. Not trusting herself in front of her parents, the young woman skipped eating and headed straight to bed.
Jae was in his room, thinking about the day's events. He was tempted to sneak into Yooyeon's room and fuck her before he went to sleep. But the young man knew that would be too big a risk.
Yooyeon struggled with the same thoughts. She wanted her Brother's cock in her one more time before she went to sleep, but knew it would be too risky to try. Her Parents would lose it if they caught their kids fucking. Yooyeon eventually drifted off to sleep. As she lay in bed sleeping, millions of her Brother's sperm swam deeper into her birth canal towards the waiting egg.
One tiny sperm cell made it to the outer wall of the waiting egg, and then bored its way inside.
