It had taken a good couple of months for my sister and I to re-establish our normal relationship. We usually shared a meal with our respective spouses about every two or three weeks, since we didn't live that far apart.
For understandable reasons, we'd had a necessary break from each other to re-establish our normal interactions. What happened was a genuine mistake.
I was proud of myself for being honest and forthright with Selena - Selena from the outset. I didn't like carrying lies and tried to not do such things.
There were two surprises from the wedding a couple of months ago.
One: I ended up eating out my sister's bald pussy. That sentence on its own requires no explanation. The way it occurred took some explaining however but was genuine. I thought that Selena and I were continuing our sexy game that had been going on all night. She feigned a headache and went to bed early. I had another couple of drinks and headed up, completely fucking up which room we were staying in and entering the wrong one -- one room short down the correct hallway. The rest of that event is contained in episode one of this series.
When I was halfway through leaving a ridiculously large load of sperm in who I though was Selena, she removed the pillow from over her face. My eyes had adjusted to the dark and we realised we were not with our respective spouses.
I couldn't stop the spurting cum exploding from my cock. I think I felt my sister grind up against me as she pushed her pussy up onto my thick cock shaft.
We made some horrendously awkward gasps as we realised what had just happened. I made for my door and left quieter than a church mouse, more embarrassed than imaginable.
Two: Not willing to live the lie, and wanting to get it straight off my chest, I went to my room, which was not a long walk, and told Selena straight away what had happened.
Expecting to be thrown out to the kerb for such a ridiculous story, I figured that if I told my wife immediately then she would see the details made sense as she supposed to be the recipient of what just transpired in the room next door.
As outlined in part two of this series, Selena made me tell her all the details of what had happened. I believe she started to get off on it a little bit, because before you know it, she asked if she could taste my sister's juices.
To start with she gently worked my cock inside her mouth, until I was as hard as I'd been some twenty minutes earlier. She had my balls in her hand as she massaged them and my perineum as she drew as much of my thick, seven-inch shaft into her throat.
Overcome with the emotions of such a surreal evening, I blurted that I wanted to fuck Selena's tits.
She was surprisingly willing and encased my shaft in her ample breasts. As I thrust harder and harder between her gorgeous bosom, she asked me if I was thinking about my sister as she rocked with the force of my thrusting. "Yes" I admitted to her. I was.
I was thinking about her and her tits.
About her pussy.
About how she tasted so good.
I was thinking that the forbidden fruit seems to be the sweetest.
Selena asked me to cum in her like I did my sister that short time ago. I didn't need any help reaching my climax. I was looking down over my gorgeous wife, thinking about my hot sister while Selena was asking me to blow my load like I just had in my sister.
After I'd lost my second load of the night, Selena looked over with soft eyes and quietly asked if I'd consider fucking my sister in front of, or with her.
And this now leads us to the current day. Two months on from THAT night.
There'd been quite a delay in any sibling contact. Likewise, Selena hadn't really brought the subject up again. She'd only joked a couple of times about it.
When we discussed that I didn't know how to speak with her again, she said that we should just have a weekend lunch like we used to do so frequently.
I'd assumed that my sister hadn't told her husband. The reason I thought this was that he really wasn't that outstanding of a human. I was sure that he'd cheated on her, yet, ironically, he would be the first person pounding down a door of someone who looked sideways at his wife. He drank a fair amount and was often away for work, giving him the opportunity to do as he pleased.
Steeling my resolve, I typed out a text after I'd just chickened out of ringing her. "Lunch at ours on Saturday -- say Noon?"
I could see that she had been active online about fifteen minutes previously, so I waited.
A reply binged: "Sure, just bring the usual?"
I replied with a thumb's up emoji. By usual, she meant drinks and dessert. Selena and I would do nibbles and mains.
The Saturday rolled around and the knock on the door gave my heart a jumpstart.
As they entered our house, my sister's eyes met mine with a lingering gaze that was both cautious and curious. As we all settled into the lounge for some nibbles, I went to our kitchen to grab some drinks out of our refrigerator.
Somehow, she ended up standing close to me in our kitchen, well away from the others. As I cracked the first beers, she moved in closer to me as she found come glasses above her head. I spoke first "I told Selena. She knows what happened."
She responded "Aiden has no idea. He'd lose his mind if he knew."
I believed her.
My sister continued "How was Selena when you told her?"
"Surprisingly OK. It was a horrendous mix-up. Thankfully she realised what had happened."
She pressed "Any issues since?"
My mind raced for a second, Selena's words ringing in my head.
"Nah. No problems."
"Thank fuck" my sister replied. Let's have a drink!
We made our way back and had a few beers before lunch. For lunch we had a chilled chicken and beetroot salad with a couple of glasses of white wine.
During lunch, I noticed Selena becoming more and more animated. She'd drag her foot up my leg. My sister kept catching my gaze as well. Her denim overalls framed her figure perfectly, with a crisp white T-shirt underneath, highlighting her firm breasts with a hint of cleavage peeking over the V-neck cut of her shirt.
The wine and beer were going to my head.
A post lunch swim was the order of the day. The afternoon sun was stinging hot. The four of us got changed and headed into the crystal blue, cool, clear water.
Usually, Selena wore a bikini, but this time she was in a long-sleeved top with bikini bottom. The zip on the swim top ran almost all the way to the waist. The small blue coloured print on her top highlighted her pleasing curves as it clung to her tanned, wet skin.
Alternatively, my sister usually wore a one-piece swimsuit. Like those used by competitive lap swimmers. This time, however, she wore a bikini emblazoned with a Scottish tartan print. It was one of those bikinis with a string that needs to be laced on the wearers back, and on the sides of the bottom.
She too looked amazing. I'd yet to see her wear something so brazen. Not that it was by any means a disservice. Based on her figure, she could wear a hell of a lot less and not get a single word of complaint from any male aged anywhere from puberty to old age.
The cleavage that I'd spied a sample of earlier was on display and in spades. Her breasts naturally sat close together, giving the illusion of a larger cup size than what I estimated to be a natural D cup anyway.
Selena and my sister were dressed oppositely to what I was used to, yet each succeeded in looking amazing.
The four of us cooled off and frolicked in the water. It's embrace was both relaxing and invigorating. In the corner of my eye, I spied my wife and my sister. The first with lust and the second with excited reservation.
As we chatted, another white wine was sipped before we slipped out of the water and relaxed on the sunbeds around our pool.
Selena and I flicked through some magazines we had, while my sister read a book, she was midway through. As we flicked pages, Selena's hand reached over and grabbed mine. She squeezed it, to get my attention.
I glanced over to her; she looked at me with a glint in her eye and slowly lifted her right hand and flicked her zipper tab upwards. Instantly the pressure that her substantial bust was under pressed the zipper apart, causing it to drop down her chest six inches.
At the same time, her left hand moved from holding mine, to grab my upper thigh and gently squeeze it.
Her bust was pressed together by the remaining pressure of her top while her hand snaked closer to my crotch.
I glanced at our guests. My sister was deep in her book, seemingly engrossed by whatever chapter she was up to. Her husband, Aiden, was lying on his side, facing away from the group. He had some earbuds in, seemingly listening to music, or a game of some sort.
A stirring in my stomach announced the beginning of the excess blood flow to my cock. As my stomach started to churn, the tightness of my swimwear began to increase.
Selina glanced towards our guests. Seeing no one was watching, she lowered her zipper another two inches. It now sat at her sternum height.
Her hand wandered over my encased cock, which was now pushing hard against my swimwear. Her eyebrows jumped with subtle surprise as her fingers completed a length over my growing issue. There was no hiding it now, I was pressing the garment outwards with vigour.
I'd chosen to wear a speedo brief instead of my usual board short fare. This only exacerbated my concern.
A couple of minutes went by. Selina continued running her fingers up and over my thigh and speedo encased cock mound. It was to the point now that if I were to stand up there'd be no hiding my predicament. Either my shaft would straighten, and the top two of my seven inches would pop out the top, or, alternatively, It would stay bent but be so pronounced that my smooth-shaven balls would fall out the side, given the strain on the fabric to contain my girth.
My sister continued with her magazine, seemingly none the wiser.
Her husband seemed to be nodding off, with his earbuds still tuning him out of any of the current circumstances.
Selena caught my eye. Her pupils were dilated. She looked at me with a lustful look that was more of the 'fuck me' rather than 'make love to me' type of mood.
My wife was horny.
Her hand wandered down once again, her fingertips slipping under my waistband. She ran her fingers over my now aching cock tip. She ran them around and over my circumcised head.
Squeezing my tip to once again get my attention, I looked up at her. She tilted her head backwards to indicate the window behind us. This was our bedroom that looked out over the backyard. There was a single access door to the bedroom that went through a small ensuite we had that was part of our bedroom.
I nodded my head. Selena stood up casually and headed inside via the loungeroom entrance that was the main thoroughfare to the backyard and the pool.
A couple of minutes later, I wrapped my towel around my waist to conceal my engorged problem and headed in via the ensuite entrance which was on the same side as my sunlounge. I was able to hide my problem by having my back to my sister and her husband as I wandered in.
