My sister Dee is 42 this year but we have been together since she was 17. I will only mention in this post about our recent get together which is all too rare. I headed down to the States for her famous summer barbecue and her in-laws were there which both she and I have come to regard as great cockblockers.
They want to be taken care of hand and foot and my sister being the great matriarch she is, makes up a fabulous spread and serves upwards of 30 or 10 people at one of these things. I try to help best as I can but the worst part is that the two of us want to fuck at some point as well.
With husband, kids, in laws galore around, we were thoroughly cockblocked all day. Surprisingly though, everyone was out in the yard enjoying the first of the food and drink that was delivered to the table while the men in the family huddled around the barbecue.
Dee and I were alone in the house. She still had some baked goods to attend to and the smell was making us both horny. There was no sound in the house and we could everyone from the kitchen window.
My sister, as strong as she is in everything else she does, can be a submissive little thing when we are together.
“You are such a slutty girl,” I whispered in her ear. She whimpered at me.
“Yes, I am,” she replied. “I've wanted you cock in me all day.”
I looked out of the window. Everyone seemed to be well away from the back door of the house. It wouldn't last long.
“I can fuck you now but that means my cum would be inside you all the time we were at the barbecue.”
Once again my sister whimpered. “Bend over the sink and keep and keep an eye out the window and I will fuck you now.”
“Oh God, really?” she cried out.
“Yes,” I answered. She bent over the sink and lifted her skirt and pulled her panties aside. She was already absolutely dewy.
“They will see my face in the window when I cum,' my sister breathlessly said.
“Good,” I said. “Then they will see how slutty you are fucking your brother and having him shoot cum deep inside your tight pussy.”
Dee groaned. I rubbed the head of my thickening cock against her wet pussy. We had no time to waste, we had only minutes to fuck and to cum. We had done it many times before and sometimes under very risky circumstances.
I pressed into her and Dee pushed out her ass, arched her back and I could see the pre-orgasmic look on her face in the reflection of the window. “Oh Jo,” she moaned. “You are such a bad big brother.”
“Shut up and start fucking me, Dee,” I told her harshly. “I am only going to pull out of you after you cum. And If you don't, everyone will see us fucking.”
“Oh God,” Dee cried out.
She started really grinding her ass against me. I slapped her hard against she ass cheek and she yelped. I pulled her hair with one hand and squeezed her ass with the other as I pounded her.
“Oh my God, someone is coming to the house!”
“Cum for me you little slut before they do!” I said to her.
This was all too much for Dee and for myself. She started babbling and groaning. I cupped my hands around her mouth and she screamed into it. She bit me too but I held tight.
“I'm cumming!!” Dee screamed muffled into my hand. “Aaahhhheeeeiie”
It was too much for me. “I'm cumming too, baby,” I said leaning down to say it in her ear. And then I filled her pussy with semen. God, it was a lot of it. I pulsed a few times inside her.
We practically collapsed onto each other. But we both heard the footstep headed up the walk to the back door. I pulled out, swept her panties back in place and and lowered her skirt.
A moment later, Dee's head was in the oven pulling out the baked goods. I zipped up a few seconds before Aunt Katrina walked in the door.
“Mercy me,” she said. “I love the smell of baked goods.”
Dee's face was flushed and her face covered with perspiration. I was a little sticky too. But it looked like we had been working hard in the kitchen. And we had. Dee used a corner of her apron to wipe some of the sweat from my forehead. I rubbed the baking powder off her cheek.
“Dee, you are so lucky to have such a good brother,” Aunt Katrina said.
“That I am,” Dee said as she looked knowingly at me.
We re-joined the party outside and Dee had my wet cum soaking inside her panties the rest of that afternoon.
Later that night, when all had gone to sleep, she came to my room and we fucked again.
