Being Bred By My Brother

Contains medical and fertility stuff that is really not founded in a reality other than this story. Contains some non consent stuff too, brief mention of gay sex (Male/male) but no anal. Written from woman's perspective, I hope you enjoy!

I had suspected them for a while. She was always friendly and nice to both of us but seemed to be a lot more 'flirty and touchy' with my brother than usual. Oh, details, Clara, details.

My stepmom was a lot younger than our dad. Our mom passed away when we were young and Dad raised us himself for a while. When he met Kendra, he became a lot happier and she really made a difference in his life. She treated us pretty well too, she owned a couple of businesses and quite a few rental properties so we knew she wasn't after Dad's money. My brother, Cole, went to college for a while on a football scholarship but after 2 years he got tired of it and got a job at a local gym instead. He was happy enough. I was not interested in college at all and had a job at a supermarket. It paid enough and wasn't stressful which I liked. My brother made sure I kept in shape. I am 5'9", short blonde hair and blue eyes. Kinda flat chested but guys didn't seem to care much and I could get my needs taken care of whenever I wanted it. Wasn't in a rush to settle down, at 19 I had way more kinks than a lot of guys could handle so I just had fun. Our stepmom was 5'11" with a slim figure, long dark hair and hazel eyes and blessed with really nice 38d's and a great ass. She complimented Dad's 6'2" handsome physique and looks. She was really pretty too and Dad always smiled when he noticed guys looking at her.

I was meant to be at work that day but they needed volunteers for a late-night audit at the weekend and I took the afternoon off so they didn't need to pay me overtime as well as the late shift bonus. It was a locally owned supermarket and the owners were really good to us so I did what I could to not hurt their profits. When I arrived home, I let myself in quietly and soon heard the noises from what I'd suspected. Dad was at work but Cole's motorcycle and Kendra's car were in the garage so I knew it was them.

His bedroom door was open enough for me to see. I stayed in the shadows and watched and couldn't believe what was going on. Kendra was on her back on the bed, she had a wedge pillow under her ass and Cole was on top of her, slamming deep into her. I could see everything, his full balls were slapping against her ass and by the cream round her pussy, she was already cumming. I should have walked away, confronted them about it later but I was horny. I hadn't been laid in a while and watching them had me more excited than I really should have been. I was soaking wet, I let my panties fall to the ground and while I slowly rubbed my clit, I undid the few buttons on my summer dress then let it fall to the floor too. I didn't need a bra so I stood naked, pinching my nipples with one hand and fingering myself with the other as I watched my brother fuck our stepmom. They were getting really vocal too, it pushed me over the edge and instead of walking away, I wanted in.

"I'm cumming again, keep fucking me with that big cock," gasped Kendra.

"I'm gonna spray so much cum in you," replied Cole.

They groaned in unison as Cole climaxed, he stayed in her until he was spent then pulled out slowly and laid on his back. He was still hard and glistening from their juices, his cock was beautiful and I wanted it. I moved quickly, I slipped into the room and got between her still-open legs and started eating her, licking and sucking her labia and swallowing the cum that had started oozing out of her already. She was still coming down from the orgasm Cole gave her so when I started licking, she was cumming again quickly. She was gasping and cumming so hard she couldn't talk. I'd never seen it before but when she peaked her orgasm, my tongue rasping her clit, she actually blacked out.

I took my opportunity and somehow Cole was still hard. He was no doubt in shock and before he could really react or say anything, I'd straddled him and impaled myself on his cock. He groaned as I fucked him, taking him deep in and out of me and I had him close before he snapped out of the shock.

"Cl....Clara, what the fuck are you doing?" he gasped.

"I was horny and I caught you, shut up and cum," I replied.

"Y.... You're my s... sister."

"And she's your stepmom."

"It's not what it, oh fuck, I'm cumming."

"FFFuuuck, me too!"

He pushed up as he climaxed, I felt his cum spray into me and I wondered at the time how there was so much since he'd already sprayed a load in Kendra but I didn't care at the time. Right as he finished, Kendra started waking up. I knew I was going to catch hell anyway so in my head what I did next was my final resistance. I climbed off Cole and straddled Kendra's head, held her mouth to my dribbling pussy until she took the hint and started licking me. Her eyes were wide and she looked pissed but her tongue felt amazing. I didn't take long to cum, I finally let go of her and shuddered to a second orgasm as she rasped my clit. When I was spent, I climbed off her and sat on his chair.

"I've never blacked out from cumming so hard before," she said quietly as she got up.

I was still catching my breath but her demeanor was a little strange. I was expecting a kind of 'oh, I can't believe you caught us' but she seemed focused. She got a bottle of water then a small pill from her bag, mixed them then handed me the bottle.

"Drink this please," she said.

"Why?" I replied.

"This, is not what it seems. Your brother is taking medication, I am too. It increases his sperm production and my fertility. This will counter it, you shouldn't have it in your system."

I was thirsty anyways, I drank the water then I blacked out.

I woke up to voices, Kendra was still naked but her hair was wet so she'd showered. I was laying on one of their loungers in their bedroom, my arms were tied and I had a strap round my waist too, pinning me to the lounger. They had a gag in my mouth too, nothing too unusual for me so I didn't panic.

"She didn't fucking ask, Gerald. She came in, ate my pussy until I blacked out, fucked her own brother and took a load of cum that belonged to me. You'll take these and you'll fuck her until they wear off," she said to my Dad.

"She's my daughter, Kendra," he replied.

"And he's your Son and she raped him and abused me. You do this or I take it another route."

"Are you going to at least tell her why she walked in on you fucking her brother and why I will be doing this."

"Fine. Oh good, you're awake. What you interrupted earlier was planned and arranged with your Dad's full knowledge. I want a baby and since your Dad had a vasectomy years ago, he agreed to let Cole impregnate me. A friend provides fertility drugs for both Cole and I so we don't have to spend tens of thousands to have a stranger put a test tube up me. You, took the second of two loads he gets every second day to increase my chances. He cums, we rest then he cums again. What I've given your Father is a cocktail we use when I'm very stressed, he'll be hard and going strong for about 3 hours. Agree to this and we can start over, fight me and I'm calling the Police. Nod your head if you agree," she said to me. I nodded.

Dad looked at me with a look of stress on his face, Kendra handed him 2 pills then got on her knees to suck him to hardness. I watched as he grew, his cock was bigger than my brother's and I knew he was going to stretch me. Once he was hard, she stopped sucking and stood to the side. Dad got on top of me and pushed his cock into me, when he started thrusting, Kendra left the room. He felt amazing, I'd never felt so full before but I felt so dirty and wrong and wanted more. I tried to talk through my gag, Dad took the hint and took it off.

"What did you say?" he asked quietly.

"Harder, Daddy, fuck your little whore," I replied.

"Y.... You're not upset about this?"

"No way, I'm a little kinky and this is pushing all of my buttons. Your cock feels so good, Daddy."

"I still don't like being forced into this."

"Well don't feel bad and just enjoy it. I love you."

"I love you too."

I couldn't tell you how long he actually lasted. True to what Kendra said, it made him more aggressive and he pretty much angry fucked me until he was spent. He came about twice, I think I blacked out once or twice and we were both soaked in sweat when he finally pulled out. He quietly untied me and carried me into the shower with him, my thighs were burning and I couldn't stand. Thankfully, theirs had a seat and gently washed me then sat me on his lap to hold me. I kissed him on the lips, he looked kind of distant and hurt.

"Dad, I really enjoyed you. This was my fault," I said, touching his face.

"I shouldn't have done it, Clara," he replied.

"And if you hadn't, she may have called the cops on me."

"I suspect she was bluffing but this medicine has made her crazy, I swear. She's getting it from pharmacy guy at your work, pretty certain she's blackmailing him. It's not exactly legal."

"Well please don't dwell on us, I'm a big girl and you felt amazing. I might seem straight laced but I have so many fantasies of you or Cole, never thought I'd get both in the same day."

Dad held me close.

"Just be careful okay, don't mess with her," he said.

Oh, I'm going to mess, I thought to myself. Dad helped me get into my bed after helping me get dried off and I slept really well. Next morning I wandered down to the kitchen and Kendra was sitting drinking her coffee naked. She greeted me with a smile, I couldn't help looking at her perfect tits.

"Good morning," she said to me.

"Hi," I replied.

She waited until I'd poured my coffee to talk again.

"So, I've talked it over with Cole and so that I'm getting the best chance at fresh sperm, on my rest days like today, you will be encouraged to fuck him," she said to me.

"Um, thought we were starting over?"

"Well, I changed my mind. He's waiting in his room, you can finish your coffee. Here, make sure you take this," she had my birth control pills from the bathroom and watched me take it then left the room.

I was a little annoyed but the thought of Cole fucking me again had me getting wet. I knew what I was going to do. When I walked into his room, Kendra was there sucking his cock. She stopped when I walked in.

"This part of your arrangement with Dad?" I said.

She stood up and looked at me coldly.

"You'd do well to not smart-mouth me young lady. Consider yourself lucky you're on the pill or you'd be taking this in the ass," she said then left.

I got onto his bed on all fours and looked over at him.

"Hey, Sis," he said with an awkward smile.

"Don't 'hey sis' me, just hurry up and fuck me, I've got stuff to do," I replied.

"I thought you wanted this?"

"One time and that ship has sailed."

He pushed into me and started thrusting. He felt good but I wanted it my way on my terms and being a cum dump to help her was not that. I kept myself tight and pushed back to meet his thrusts and before long he shuddered as he filled me. I got ready to get up when I felt his cum spill out of me but he stopped me and reminded it was two loads. I actually came that second time but I was pretty annoyed. I cried in the shower. I felt so used and trapped, my own damn fault too. I dried myself off and went over to my friend's house.

"Well, you look like shit," she said smiling as she greeted me with a hug.

"Fuck you too, bitch," I replied and hugged her tighter.

"Ooh, hey, are you okay?"

I told her everything, she sat with her mouth open when I was done.

"What, the fuck! The challenge was a joke, I know you're kinky as fuck but I didn't think you'd actually do it. Fuck Cole maybe but your Dad AND your stepmom? Holy fuck. What are you going to do, sounds like she has you over a barrel," she said.

"Remember when I told you I had no idea what I wanted to do with my life?" I said.

"Um, yes."

"I'm going to have a baby, my brother is going to get me pregnant."

"What? Clara, that's crazy!"

"No, it's not. She'll be forced to help take care of me or risk exposing herself. Her little plan of one little baby is going sideways too, I know who she's blackmailing and he's a really nice guy. I'm sure he'll help me."

"You need to take time and think about this. Fucking your brother is messed up, sure, but intentionally getting knocked up by him? What will your Dad say?"

"Well, I'm not going to tell him. He could barely look at me when he helped me into bed."

"Well, you fucking won. There's no way I could top this for the most fucked up sex partner. Do you want me to eat you now or some other time?"

"Believe it or not but this nympho is a little off sex for the day."

I kissed her then called my Dad, had him meet me for lunch. He still couldn't give me eye contact but I hugged him and kissed him on the cheek.

"How long are you going to be like this with me?" I asked when we'd sat down.

"Like what?" he replied.

"Like you walked in on me masturbating with your tv remote. I love you, can we put what we did behind us?"

"I'm not sure I can, honey. If it happened differently, I maybe could have lived with it. You get your kinky from your mother and well, I'm open minded but there is a line and she pushed me over it."

"What are you going to do?"

"I think I'm going to leave, Clara. Your Uncle Frank tried to tell me a woman as young as she was when we met would be hard to keep happy but I love her, she's beautiful, smart and everything I was looking for but I don't think I want another kid and she's not backing down on it."

"You tried to talk to her?"

"Yes, we had a long chat into the night, why I'm so tired. I told her if she wanted to keep fucking Cole, I could live with that but I didn't want to have a kid again. She looked at me coldly and said, 'well I do and I'm going to get pregnant'. The look in here eyes scared me, Clara."

"Okay. I love you, I support what you want to do."

"I'm going to go and stay with Frank for a while to give myself space to think things over. You and Cole will be fine but if she gets too crazy, you can come with me."

"I'm going to be okay, Dad."

"Well, I need to get back to the office. Tonight isn't likely to be fun at home."

I hugged him and made my way back home. That night was different than I expected, Dad told her she was leaving and she told him she didn't care. Dad was hurt but I guess it made his decision easier. He packed a few bags and loaded them in his car. He hugged me then drove off. Less than two hours later she was already fucking Cole in his room. I went out and had dinner with my friends and when I got home, Kendra and Cole were sitting on the couch watching a movie. Nothing unusual there but they were both naked. I tried to just sneak off to my room but she called me.

"I decided and Cole agreed, this is now a nudist home. We've also found out that the medication is making him produce too much cum so you need to do your part to keep him level. I will take him all day on my fertile days but when I send him to you, it will be for sex," she said.

"What? You can't expect that of me, are you nuts? You and him can fuck all you like, that's between you and Dad but you don't get to tell me to just lay down and take it," I replied, I was pretty mad.

"Are you forgetting you raped him, you started all this."

"And you had my own Dad fuck me for 3 hours in return. I'm not doing this, I'm 19, I'll wear what I fucking want and I will fuck who I want on my terms."

She pulled out her laptop from a bag at her feet, clicked a few things then showed me the video. It was of my Dad fucking me hard on the lounger. It must have been while I was either blacked out or zoned out or something because I didn't remember her being there. I could hear her voice as she approached him with the camera.

"Is she nice and tight for you, Gerald?" she said.

"Yea, she is," he replied, still slamming into me.

"Do you like fucking your own daughter, baby?"

"Yea, she feels so good."

She stepped back with the camera to show his and then my face. I had started to wake up, I had a kind of glazed - 'oh this is good' look on my face and just looked up at my dad as he continued to fuck me. Kendra closed the lid on her laptop and put it away.

"I'm sure the board of directors that your father sits on would love to see that," she said, coldly.

"That is your husband, have you forgotten the 7 years you've been married?" I replied.

"Well, I'm with Cole now, he's going to give me what I really want. Do as you're told and that video will go away."

I was shaking I was so angry. Cole couldn't even look at me, he just rubbed her thigh and looked down. I walked away and went to my room. I would have locked the door but it had been removed.

"Are you fucking kidding me," I said aloud.

"Kendra didn't want you just locking yourself away or slamming your door. Once she's pregnant and we're done with the medication, you can go and live with Dad. Just play by her rules and you'll be fine," said Cole, I didn't see him follow me.

"Be my big brother's little cum dump for stepmom, got it."

"It's not like that, Clara."

"It fucking is like that, Cole. You used to care about me, you've beat the shit out of more than a couple of guys who hurt me, is her pussy that good, it has you forgetting who you are too?"

"Just think of what that video would do to Dad's reputation at the firm," he said coldly then walked away.

The following few days put me in a pretty horrible mindset. Kendra would watch after she brought Cole to me. He'd put me on all fours, rub my pussy long enough to get me wet then just fuck me until he was done. I was only allowed to dress to go to work, supervised when I took my birth control and any time I showed resistance she would just open the laptop and glare at me.

I sat in the breakroom at work that Monday, I was tired from being woke up for sex twice that morning but I knew I had to change my path. I made myself smile and went to see my friend Steve in the pharmacy.

"I need to know what she has on you, Steve," I said after greeting him with a hug.

"Come through to my office," he said, looking around.

He had me sit then closed his door.

"Are we talking about the person I think we are?" he said to me.

"Kendra," I replied.

"Fuck. Are you with her, does she want more?"

"With her.. Fuck no! I need to get my life back and I think we can help each other."

"Sh... I need you to swear to me this goes no further. I'm already in deeper than I can handle."

"I won't tell a soul."

"She caught me at a certain club for adults in the city. She was there with your brother and let's just say I was in a compromising position. She told me if I didn't give her the pills she needed she would tell my wife and everyone I work with."

"Tell your wife? About what?"

"I... I was being fucked by one guy while I was sucking another. She had me suck your brother at her hotel room and taped it, there was no cameras allowed in the club but she taped me talking about how much I enjoyed it."

"She has video of my Dad fucking me, is holding that over me too. The pills have made them fucking crazy, every morning and sometimes two or three times a day she'll bring Cole to fuck me."

"I'm so sorry, Clara, this is all my fault."

"No, it's not."

"The pills were pulled from the market just last week because of the side effects. Mixed with certain pills, mostly over the counter stuff like allergy medication, they have been known to make people act this way. I haven't had the chance to destroy my stock yet."

"She doesn't know that right?"

"No but she has a 6-month supply for them both. She should be pregnant soon then will have to stop taking them. He will be extremely virile for a month or so after he stops, I'm glad you're taking birth control."
