I woke up on Sunday morning from the kind of deep, relaxing sleep you have after a good, satisfying fuck, and I lay there looking at the ceiling for a moment until I remembered. Last night I had fucked my own sister, Kelly. Those same conflicting feelings that I had felt as I walked from her room and climbed into bed last night came back, and I wondered if things could ever be the same again. I thought that maybe I needed to find a reason to leave and go back to my own home, but then I smelt breakfast and heard the sounds of talking and laughter from the kitchen.

I got up and pulled on a tracksuit, then walked down the long corridor to Kelly’s kitchen, and I found the three kids sitting at the table demolishing breakfast, while Kelly stood at the stove. She was wearing the same jeans and horizontal rainbow striped tank top she had worn last night, but she looked freshly showered and ready for the day. She turned and smiled at me and said, “Well, there you are. I was about to send Greta down to wake you up.” She gestured at the empty chair at the end of the table and said, “Have a seat, breakfast is ready.” She stepped over and placed a plateful of pancakes, eggs, and bacon on the table as I sat down.

To my left at the rectangular table sat Lexi, and on her left was Aiden, her brother, and Greta, my daughter, sat opposite him on the other side. To look at them, no one would ever know that last night Aiden had fucked her, doggy style, as she went down on Lexi in the moonlit field outside, but I knew. I knew because I had watched this shameful spectacle as I fucked my own sister at the window.

The three kids were talking excitedly about their plans for the day. The big tavern at the turnoff on the road into town was having a rock and blues festival all day, with three local bands, and they were all planning to head over there after we tidied up after last night’s joint birthday party.

I looked across the table at Kelly, sitting at the far end, and she showed no signs of anything unusual, although I thought I caught an ironic glance from her at one point. Perhaps it was just my imagination, but I said nothing. I pondered the whole situation, but after a few minutes, Greta piped up and said, “You’re not saying much, Dad. Are you feeling okay?”

I cleared my throat and said, “I’m okay, I, umm, just think I might have had one too many beers last night.”

“Really?” Greta answered, sounding genuinely surprised, “You didn’t seem to have that many.”

“Well, you get to a certain age,” I said, trying to deflect the conversation, “and you just can’t handle it like you used to.” The truth was that I had paced myself last night and was not hungover at all, but I didn’t want Greta or anyone else to think I had anything on my mind, like for instance the fact that I had gone balls deep in my sister’s pussy at the window after the party.

“Come on, Ryan, you’re not that old,“ Lexi said brightly, smiling at me with a knowing glint in her eye, “and I’m sure you’ve got plenty of stamina, once you get going.” I looked across the table at Kelly, and she made eye contact but she said nothing, and then her eyes dropped to her plate in front of her.

After breakfast, and a much-needed shower, I helped Aiden and the girls to clear away the tables, chairs, and other items we had used for the party, and as I looked down at the flattened patch of grass where their sexual threesome had taken place, I couldn’t help seeing it again in my mind, but the kids were totally oblivious. Then it was time for them to head into town for the music festival.

Kelly came out of the house, and as the three young ones climbed into Aiden’s twin cab pickup, chattering excitedly, Kelly said, “Now, don’t forget, if you have too much to drink, just ring Ryan or me and we’ll come and get you. No driving after you’ve been drinking, okay?”

“Yes, Mum,” Aiden said, as he put on his seat belt, “No driving after drinking, we get it,” but Lexi leaned over from the passenger’s seat and said, “We’re going for the music, not just to get drunk.”

“I know,“ Kelly persisted, ”but one day when you’ve got kids of your own you’ll understand. Just ring, okay?”

A few moments later, Aiden drove down the long driveway, and left Kelly and me standing outside her house. I wasn’t sure what to say, or even if there was anything to say. Even so, Kelly was no different from any other day. “Off they go,” she said, and then added, “I’m going up to feed the horses, you want to come?”

“Think I might stay down here,” I said, feeling awkward about what sort of conversation we might have if I went to the stables with Kelly.

“Suit yourself,” she said, smiling, “Might even have a little ride after I feed them, so I’ll see you shortly. I’m sure you can amuse yourself.” There was absolutely nothing unusual in her tone, and she turned and walked away towards the stables, and left me there to my own thoughts. After a moment of contemplation, I walked back inside and went down to the room where I had slept. I climbed on the bed and thought about last night, and what it all meant. Maybe I should go home early, I thought, perhaps tell them I was feeling sick and needed to go home, so they could stay and enjoy themselves.

Then, I thought, Greta might want to drive me home herself, if she thinks I’m sick. That would ruin her long weekend. I sighed, thinking of all the different ways I had fucked things up. “Fuck me!” I said, out loud. I lay there for quite a while, tossing all kinds of ideas through my head, but then I heard footsteps in the corridor, and Kelly came to the door. She was still wearing the rainbow coloured tank top but I noticed she had changed from her jeans into a short blue denim skirt. Even at thirty-nine, she had the legs, and the figure, for it.

“You okay, Ryan?” she asked.

“Yeah,“ I said, but even I could tell my tone of voice said I was not okay.

“Something’s wrong, isn’t it?” she said, from the door.

I looked over at her but I said nothing, so she added, “Can I come in?”

“It’s your house,“ I said, keeping my tone light so it didn’t sound sarcastic.

“Yeah, but it’s your room at the moment,” she said, as she stepped over to the bed. She sat on the right side of the bed, and turned to her left to face me. “It’s last night, isn’t it?”

“Yeah,” I answered, sighing the word as I spoke.

She kicked off her sandals and slid onto the bed so she was leaning against the headboard with her legs bent, feet flat on the bed, and she said, “It’s not that big a deal, Ryan, really.”

“How can you say that?’ I asked.

“Look, it really isn’t a big deal. It was just sex.”

“That’s kind of the problem,” I said, “We shouldn’t have done it.”

Kelly shuffled herself down to lie next to me on my right, and she turned to face me and put her right hand on my chest. “Just think about it for a minute,” she started, “Okay, we did something we weren’t supposed to do, but when you really look at it, why is it a problem?”

I looked at her again without answering, so she continued with, “The reason it’s not supposed to happen, and brothers and sisters aren’t supposed to do it, is pregnancy. That’s the only real reason, but we both know, I can’t get pregnant.”

“I think there’s more to it than that,” I answered, but Kelly was not swayed.

“You know, think of it this way. You and I could have gone to the festival with the kids today, and either one of us, or even both of us, could have met someone and had a one-night stand, right?”

“Yeah,” I answered, unconvinced.

“So, if we did, we wouldn’t be trying to have a child with them, would we?”

“No,“ I conceded.

“So, really, in the overall scheme of things, what’s the difference if you and I did it together? It means just as much.”

I felt my brow wrinkling at that, and I just had no way to answer, but in a way, it seemed to make sense. Then, Kelly leaned in a little closer, and with her face close to mine, she said, “In fact, we’ve got the place to ourselves for the rest of the day.”

“Seriously?” I said, but I had to admit that I felt a little wave of excitement as she said that.

“Well, why not?” Kelly answered, “Like I said, I can’t get pregnant. I had my tubes tied nearly twenty years ago, so it can’t happen.” She moved even closer, sliding her arm around my left shoulder, and kissed me gently on the mouth. “No one would ever know, except us,” she said quietly after she broke the kiss. I felt her warm breath on my face as she spoke.

I think it was at that moment that I was convinced and that my sister had talked me into fucking her again, but I could not find the words to say I agreed with her, and that I wanted it as much as she seemed to want it.

Kelly shuffled a little closer, still lying on her left side, making eye contact and seeming to wait for my response. “You know,” I said, choosing my words as I spoke, moving into uncharted territory here, “You do have a point.” Kelly started to smile, and once again she kissed me, still a gentle kiss, but held a little longer, with her mouth a tiny bit more open. I felt again a cold wave of excitement running through me, and I reached forward, a little tentatively at first, and placed my left hand on her left thigh. She looked down at my hand, momentarily, and then back at me, with an expression on her face that seemed to invite further exploration.

As the full reality came to me, that once again I was going to do this, I decided that if I was going to fuck my beautiful sister again, I was going to make an occasion of it. I was going to taste her pussy. I loved going down on a woman, and the thought of going down on my own sister was almost unbearably exciting, but how did I bring up the subject? How does a man tell his sister he wants to taste her pussy juice? To explore her most private recesses with his mouth? I had no words for that.

I moved my hand, gently, between her thighs, and then upwards towards her crotch, under the hem of her short skirt, which had ridden up a little when she shuffled down on the bed. My hand was against the gusset of her panties and I felt the warmth from her, and again she looked down at what I was doing. Her smile seemed to be one of approval, and I moved in and kissed her pretty mouth, the first time I had initiated a kiss so far. I held the kiss for a moment, as my hand worked its way a little further under her skirt. Then, I broke the kiss, to see her reaction.

Kelly responded by parting her legs just a little, inviting my caress, so I felt gently for the leg band of her panties, and I worked my first finger inside. As I did so, I kissed her again, and she moved her left arm in, and put her hand behind my head, holding my mouth to hers as she parted her lips and introduced a little tongue to the equation. This was an exciting kiss, and I felt a hunger for her body growing inside me, as we kissed like that.

At the same time, I was gently working my finger inside her panties, feeling at first her pubic hair and then the slippery wetness of her inner lips. As my finger made contact with her sensitive pussylips, she flinched a little, but she held the kiss a little longer and then broke it, making eye contact with me as I worked my finger inside her. I probed a little further into her pussy, feeling the very entrance to her womanhood, and the slippery silken walls that had milked the seed from my hard cock last night. Neither of us had spoken for some time now, but Kelly took a long sigh as she looked down towards her crotch again.

I withdrew my hand from her underwear, taking care to keep as much of the juice from her pussy on my finger as possible, and I pulled it out, glistening with her nectar. She looked at my hand as I brought it to my face, and again without speaking, I held her gaze for a moment. She seemed to approve so far, so I placed my finger in my mouth, tasting the sweetish, tangy juice from my sister’s pussy.

Kelly was the one to break the silence. “You know, I’m getting the impression you’d like to go down on me,” she said, smiling sweetly but with a hint of mischief, “and I should tell you, I love it when a guy does that, so I’m not going to stop you, if that‘s what you want.”

“You okay with that?” I said, speaking quietly even though we had the whole house to ourselves.

“I’m ready if you are,” Kelly answered, and she moved onto her back, and shuffled down the bed a little more, causing her skirt to ride up even further. I now saw that she was wearing sky blue coloured cotton briefs, and the shuffling had pulled the crotch tight around her pussy, outlining her swollen vulva. She lifted her hips and reached behind herself, undoing the button and the zipper at the back of her skirt, and then sliding the skirt along her legs, bending them to get it off, and then dropping it on the floor. Then, she lay back on the bed and relaxed, as I moved over to kiss her again on her mouth. There was more tongue than before, but this time it was the soft, sensual kiss of two people who were about to make love, brother and sister or not.

I broke the kiss and placed my left palm over her mound, with my fingers trailing between her legs, feeling again the warmth from her pussy through the thin cotton material. I sat back and then moved my head down to kiss her through her panties, my mouth resting just about where the top of her slit would be, and I inhaled gently, taking in the sweetish scent. Then, I lifted my head, sat back a little, and took hold of the waistband of her panties at both hips. She lifted her bottom, and I slipped her blue panties down, revealing her pussy for the first time. I slipped her panties off, along those shapely legs, and I dropped them on the floor on top of her skirt.

Kelly’s pussy was natural, with a triangle of golden brown hair, and the sight of it caused another surge of sexual excitement to course through me. The impromptu nature of our fucking last night had not even given me a glimpse of her pussy, but now I could take it all in, as the aroma of her arousal filled my senses. I leaned in again as she parted her legs a little more, and once again I paused just to inhale the scent of Kelly’s cunt.

Then, I tilted my head slightly, and kissed her gently on her inner lips. I held the gentle kiss momentarily, and then I slipped my tongue between them, tasting her most intimate place. A man is not even supposed to see his sister’s pussy, and certainly never meant to taste it, and explore it with his mouth and tongue, or to inhale its intoxicating scent, but I was doing all of these things with my lovely sister. I heard her take a long breath and exhale a sigh as I licked her, sweeping her oozing juices into my mouth with my tongue, tasting them, and becoming more excited with each breath I took, infused with her womanly scent.

Last night, I had fucked this pussy, but it was a quick and dirty coupling at the window, with no preamble, no foreplay. It had been a frenzied act of incestuous intercourse between a brother and sister, overcome with lust and desire as we watched our collective teenage kids in a passionate threesome outside in the moonlight. Today was different. We had the time to do it the right way, if such a thing could be said about Kelly and me, brother and sister, satisfying our needs together like this. Today, there was time for me to explore her pussy, to get up close and personal with it, to get to know it intimately, before occupying it again with my hard cock.

After I had spent a few minutes licking and tasting Kelly’s pussy, I moved my head to place my lips around her clit and its hood, feeling her shudder as my mouth made contact with that special place. I worked the tip of my tongue into her hood, brushing gently against her clit, and again she shuddered and flinched, so I began to work her clit with my mouth. Her pussy was now flooded with juice and I felt I could make her cum with my mouth, so I was tempted to...
