“Are you alright?”
“I’m fine, I’m fine.”
“What was that all about?”
“First date gone a bit awry,” she said. “He was charming over dinner, but as soon as he got his cock out…”
I stroked her hair, and said nothing.
“He had such a nice cock, too, Will. What a waste.”
She pulled away from me and went to the kitchen. “I’m having some wine. Do you want some?” removing the rest of her clothes as she went, and dropping them on the floor.
“Sure,” I said. I started pulling my beach clothes off. “I’m just going to jump in the shower, OK?”
Once I was clean and refreshed, I joined Joan in the lounge room, where there were two glasses of red waiting. I sat down next to her on the couch and took a sip of the wine.
It should have been very relaxed, just naked on the couch with some wine. Joan had put some music on on the TV.
“I just,” she said, at length, “haven’t had an actual fuck in ages.”
I sighed. “Believe me, I hear you.”
“I had hopes for tonight. It can be frustrating.”
“It can! Don’t let it get you down, Joan.”
“I’ll be alright,” she said. “How was the swim?”
“Oh, it was fine,” I said. I wasn’t sure what else to say. “Bit chilly.” I didn’t want to mention the discussion with Dave. “Have you been doing much dating?” I asked.
“Not a lot,” she said, “but I thought I should get back into it.” She turned to me and smiled warmly. “I really enjoy what we’ve got going on here,” she said.
“But,” I said. “It can’t last.”
“It can’t last.”
My sister and I were often on the same wavelength, sometimes without even realising.
“What about yourself?” she asked me.
“I haven’t put a lot of thought into it, to be honest. A relationship is a lot of work, you understand.”
“Yeah,” she said. “Meanwhile, you have me.”
Same thing Dave had said. “There’s something I need to get off my chest,” I said.
“What’s that?”
“Earlier, at the beach, Dave asked if you and I were fucking.”
She made a face at me, furrowing her brows deeply, her mouth slowly falling open in disbelief.
“It seems like a strange thing to ask, right?”
“It does,” she said. “What prompted it?”
“He says he feels like he saw us touching, or picked up on a ‘vibe’.”
Joan put her glass down on the table. Leaning forward on the couch and rubbing her temples, “Fuck my life.”
I said nothing.
“Let me get this straight. You and me, we can’t fuck… but everyone thinks we are anyway?”
“Not everyone,” I said.
She got up and went to her room, muttering as she went, “Fuck my life. Haven’t fucked in an age… men with their pricks… all the fucking men are pricks… all pricks except my brother…” rising steadily to a roar, “my own brother who I can’t even fuck. Fuck my life! I need to fucking FUCK!” She slammed the door behind her.
I sat on the couch in silence and finished my wine. I thought I’d better go say something. I got up and trod as quietly as I could to her bedroom door and knocked.
“Joan?”
No answer.
“Joan, I just want you to know you’re not alone. It’s OK to be angry.”
No answer.
“You want to talk about it?”
Slowly but surely the door creaked open. There, on the other side, my naked little sister was crawling back into her bed and pulling the covers up to her nose.
I walked in and closed the door behind me. Gently I climbed into the bed next to her. Once I was snugly under the covers, she rolled over and put her arms around me.
“I don’t want to talk about it though,” she said.
“I understand.”
Without saying another word, she reached for my flaccid penis.
Silently I began to play with her breasts.
Soon I was hard in her hands. I reached for her pussy.
She spread her legs for me, a thin string of juice hanging between her parted lips.
I ran my fingertips up and down her slit, doing small circles around her clit.
She got up and straddled me so her pussy was right at the end of my cock.
“We can’t fuck,” she said softly, “but if we could, would you want to?”
I looked in her eyes for a moment, trying to see what was there. I couldn’t figure out what was going on in her head. But my sister and I are often on the same wavelength without realising.
Eventually I smiled. “Yes.”
“Yeah,” she said smiling back.
Slowly, deftly, she manipulated my cock so the head was resting gently right at the entrance to her vagina.
“We can’t,” I said.
“I know, I just want it right there for a little while.”
“OK.”
Gently, she rocked back and forth on my cock, lifting up and down ever so slightly, so I could feel the rhythmic change in pressure right on the tip.
“And if we fucked,” she said, “would you cum inside me?”
“Of course,” I said, “if you wanted it too. As long as you were on birth control.”
“I am,” she said.
Slowly but surely, her rhythmic lifting and falling increased in intensity. I could feel the rim of her vagina pushing and pulling against my foreskin, moving it up and down over the head of my cock.
So close. I could imagine what the inside of her soft vagina felt like. How much of the head would it take to count as penetration? What counts as “inside”?
“My legs are getting tired,” she said. Then, she sat down, taking the whole length of my very hard penis deep into her vagina, all the way to the end.
It was too much for me. I came immediately.
Feeling me pulsing inside of her, she started to cum as well.
For a moment there was no ground rule, no Dave or other people, no ancient natural law, no world at all.
Only this incredible sensation, the one vagina I had always wanted my penis inside, from the very earliest days of my sexuality.
“Oops,” she said softly.
All at once it became clear in my mind. I had never admitted it to myself.
“I just realised…” I said to her.
A wide, knowing smile spread across her face.
“I’ve actually always…”
“Yep,” she said. “Since the first moment…”
“You had just turned 18…”
“I recall every detail…” she said.
“Vividly…” I said.
“And all that time since…” she said.
“I’ve dreamt about it so many times,” I said.
“I think we’re on the same wavelength,” she said, and pressed my shoulders with her palms.
“It’s quite satisfying, really.”
“Extremely.”
Over the following weeks, we fucked a lot. We fucked in as many positions as we could think of, in just about every part of the house. I shot so many loads into my little sister I lost count.
Then, one day, she was leaving. She’d saved up enough to put a deposit down on a mortgage, and she’d been approved by the bank. It was time to move on with her life.
“Well,” I said, putting on a brave face, “it was truly a pleasure having you, little sister.”
“Will,” she said, “I want you to know that I have no regrets. No-one needs to know what happened in this house. They wouldn’t understand. But I’m not ashamed.”
Incest between consenting adult siblings is presently a criminal offence in the UK. In the real world, the vast majority of such acts go unreported. The stigma against incest is so great, that most of the people engaging in this activity take the secret to their graves. There is no reliable way to estimate the prevalence of incest between consenting adult siblings in the UK.
How many people do you know who have had consensual penetrative sex with a sibling?
“None”?
How sure are you about that?
How would you know?
Try not to overthink it.
