Jo still knows it’s wrong, but she knows she needs to listen to her future brother-in-law

I got to cleaning up the rug from all the cum jo and I had produced. I could hear them in the bedroom talking about the wedding stuff susan had bought. I walked past the bedroom door. Jo happened to look toward the door and saw me standing there. Susan had her back to the door and so couldn’t see me. She was too engrossed with the wedding stuff she had bought anyway. I untied and dropped my shorts to the floor. Jo could see I was hard and wanting her. Unknowingly I’m sure, she licked her lips.

“I’m going to have a quick shower babe” I said, meant for susan to hear, but meant more for Jo.

“Ok dear”, I might have to leave you alone again with Jo though. I think I forgot a few things. “Is that alright hunny bunch?”

I almost puked when she called me that, but said, “ya, I think I can handle being alone with Jo again. She’s not too much trouble”, I laughingly said.

With that, I picked up my shorts, grabbed my cock and started stroking it so Jo could see, and then walked to the bathroom and into the shower.

The hot water felt good. Thinking of what had happened and how we had almost got caught made raping my sister-in-law even my exciting. She did say “no” so I guess it was rape, but her legs spread sooo easily that I could tell she needed it as much, or more, than I did.

I few minutes later I heard a knock on the door. “Come in”

I thought it was susan, but it was Jo, “are you going to be much longer, I need to go pee. The cum has been in me waaaay too long and it’s seeping down my leg. She almost caught on that something wasn’t right”.

“Come on in. Has she left?”

“Ya, she just left”

Ok, then come on in the shower!”

“No it’s ok, I’ll just pee and leave”

“COME IN THE SHOWER, NOW”

With that, she entered the shower, naked.

“So go pee”

“Right here? In front of you?

“DO IT”

And after a second or two of hesitation, a yellow steam started flowing down her leg, mixed with white globs of our cum.

“ahhhhh, that’s better” she said and with that, I started peeing on her leg mixing my pee with her pee and our cum.

“What are you doing?” she said in surprise and then a smile came across her face, “that’s real warm”

We finished peeing and I spun her around. I made her bend at the waist and hold onto the wall. She felt my cock at our slit.

“What??!!, NO, We can’t!! We did it once and we can’t do it again. It’s not right”

With that, I shoved HIM forward and into her just flushed out pussy.

“noooooooooo”, she gurgled, but made no effort to stop me.

I grabbed her slim hips and started pounding away and her. She got into the rhythm as I knew she would and met each of my thrusts driving my cock ever deeper into her. She was panting. I was grunting. My balls were slapping her clit unmercifully. I grabbed her tits and pulled on them.

“noooo”, as I tortured her rock hard nipples. ’You can’t do …..” and with that, I felt the walls of her cunt grip me making it hard to keep up the thrusting. She had stopped and then violently shutter. I could feel her cumming around my cock and that was just too much for me to handle. With one last thrust, I drove HIM as deep into her womb as I had ever been and unloaded searing hot loads of baby juice into her. I growled as I came and she knew I was impregnating her again; twice in a couple of hours. My spasms seemed to coincide with her’s as we came together over and over.

Finally, the spasms subsided. HE slowly softened and slid out of her. She could feel it soft against her leg and then our cum started flowing out and over my cock head and down her leg.

“We can’t do this! It’s wrong.” She insisted.

“You wanted it more than I did!”, I replied. “You didn’t HAVE to come in here to go pee. The bathroom in the bedroom is a lot closer”

She turned around and looked down and without saying a word, reached inside her cunt and scooped out 2 fingers full of our cum and brought it to her lips.

“LICK IT”, I said. Obediently, she did, looking at me while she sucked on her fingers. I stuck two fingers in her and rubbed her g-spot causing her to shudder. I rubbed it a bit more than brought my fingers out and put them to her mouth. “Have some more as you obviously love it”. With that, I put my fingers in her mouth and she sucked them in like a pro. I could feel her tongue licking all the cum off my fingers, till they were licked clean.

“Enough” and with that she washed me and then herself. We got out of the shower and she dried me with a towel and then herself.

“So show me what susan bought for our wedding nite.”

With that, she disappeared into the bedroom and closed the door behind her.

I walked out of the bathroom and sat on the couch. A few minutes later Jo came in the living room. She was clad in virginal white, almost transparent baby doll that just covered her hips. “Let’s see the rest!”

With that she lifted the baby doll up to her waist. I could see her still very puffy lips thru the thin see-thru mesh fabric of the white v-string. “Turn around.”

“Why”, she said, “you know susan is going to know something is wrong when she goes to put this on.”

“TURN AROUND I SAID” and with that, after glancing at my swelling cock, she turned around. “Get down on all fours like a good girl.”

“But I have to go take this off so she doesn’t know it’s been worn”, Jo said.

It’s not just going to show signs of being worn I thought to myself, my cock, for the third time today, had risen to do what it’s meant for.

“NOW DOWN BITCH,” I needed Jo to know I was tiring of her care for her sister and what we were doing. I was the only one she needed to be concerned about and doing what I wanted done.

“I’m not a bit–” and with that I pushed her down and she fell on all fours. “Hey, I’ll tell susan if you don’t stop this right now”

“Oh, you are going to tell her NOW are you? And when she asks about earlier and why you didn’t tell her then? What are you going to tell her? And the other times that every opportunity susan was away, you’d flash your tits and/or pussy at me?”

“Well, she’ll understand, and I didn’t mean for you to see my breasts and pussy. She’ll believe me”

“I’d guess again girl. You’re sister has seen you flaunting yourself and she’s mentioned it to me. She’s even asked if I’d want to fuck you. Each time she did, I’d tell her that she was the only girl for me and that you were too young anyway. And your stupid sister believed me 100%. So you can tell her what you like; I’ll just deny it. And we BOTH know who she’ll believe. I know she is after my money; SHE’s the dumb one, NOT me.” And with that, I got up, walked in front of her, laid down in front of her and command, “now suck like I know you can”.

“No, I can’t do this anymore” and started to get up.

Before she had any chance though, I grabbed her head and pulled it down on my waiting cock. Instinctively her mouth opened. Her mind said “no”, but her body said “yes”. She sucked like a pro. I took my hands away so she could control how much she took in. I watched as each time she sucked on me, my cock went deeper in her and eventually it was going down her throat. It felt almost as good as her pussy. She initially had gag reflexes, but eventually relaxed and took it all. I was fucking her throat and SHE was the one controlling the fucking. I could feel my balls hardening. She could too as she squeezed them. We both knew it would be long. She pulled my cock out of her mouth and started stroking it hard and fast. She wanted me to cum on her tits. I WAS GOING to cum down her throat. She watched me; I watched her. Her little hands were stroking me like she’d been doing this all her life. (And in reality she had been, well, since her Dad showed her what to do.) I could feel myself getting close. I could feel the sperm starting to move. “Enough” I said, and grabbed her head and forced my cock into her mouth.

“N….” is all she got out as I slipped in her mouth and down her gullet. The tightness was too much. I exploded down her throat. Instinctively I could feel her throat swallowing my cum. It felt like she was trying to swallow my cock. She was beating on me to get me to stop and she tried to pull away. I held her tight and shot 2 more times down her throat. In a moment of desperation, she pushed with all her might and pushed me away. She took a deep breath as I shot a final load on her face.

“We can’t do this”, she pleaded, “we are going to be family.”

“Ya we are”, I said, “and I know how your family works.” “Susan told me how your dad treated you girls as you came of age and that your mom did nothing. She told me about how you were the only one that was able to resist. That’s another reason why she thinks I won’t fuck you; she thinks you are too moral and too strong to let me. Little does she know that her sister is a cum slut!”

“I am not a slut!! You take that back!”, and with that she was on me. She started beating and punching me in the chest.

I just laughed which made her even more angry. As she was swinging her fist, the loose baby doll top flew about giving me glimpses of her breasts. The nipples were rock hard I could see. She was getting off on this. Then I noticed as she punched, her legs, which now had straddled my thigh, were moving back and forth over my thigh muscle. Quickly I noticed my thigh getting wet. She was REALLY getting off on this. Finally, I had had enough of her tantrum. I pushed her off. She fell onto her side and I quickly got onto. She started squirming and struggling.

“Get off me you asshole!”

“Asshole am I?”, I said. “You are enjoying this more than me I think.” And with that I got her on her back and pinned her down with my legs. She saw I was hard again which made her struggle more. He was still glistening with her saliva. I quickly switched positions so I was facing her feet, my legs still had her arms pinned, my balls now hovering above her mouth. “Let’s see how much you hate this”, and with that I pulled the soaked panties aside and slide two fingers into her soaked cunt.
