"It wasn't my idea, it was hers!"
My voice was high pitched, desperate, panic struck. My beloved wife, Eve, seemed to grow before me to the size of a monstrous giant. Or was it I who shrunk? God knows I wasn't proud of myself. Damn it, I sounded like a little boy, caught breaking his first window on purpose. Or caught masturbating, which was a wee bit closer to the truth. But I am not a boy, hell, I'm over forty, growing overweight and losing hair. I should not even need to explain what I do. But I suppose I am a sissy. And given the circumstances, I could not really deny my better half at least half an explanation.
Actually, it was my sister's idea. My dear sister Shesh. To her defense, I might add that she was a bit drunk, but really, I don't think that her being tipsy had anything to do with it. Two years my senior, she has always been the adventurous one in the family.
She had handed me her bold suggestion on our way back from a late night swim in the sea by our summer house; it was midsummer so even though it wasn't daylight, it was by no means dark outside. Since lunch, we had been indulging in food and drink, in accordance to the demands of family tradition. When she suggested a swim, I was a bit cautious – drinking and swimming are bad companions I think – but she insisted and started taking her clothes off. Shortly, with her thumbs under the rim of her panties, she gave me a teasing look and asked if I was not coming after all. With a sigh of discomfort, I followed her example and as I watched her walk into the water, I undressed and followed her with my eyes. Yes, however forbidden territory, my sister is a beautiful woman; always been. Had I ever nurtured a secret fantasy, it was to make love to Shesh. I shook my head. A married man, still obsessed by his teenage fantasies. Maybe it was the result of a long day's consumption of beer, but I realized that looking at her entering the water; her well-sculptured behind swaying from side to side, the bouncing of her breasts as she turned to me, jumped and shouted to me to hurry up; it had the most profound effect on me.
I hurried into the water, hoping that it would be dark enough for her not to notice my semi-erection and that the cold water would help me literally cool down.
The planned seemed to work. We swam for several minutes without saying much; around a little rock some hundred meters from the beach and back again. Then she slowed down and started to tread water. She gave me a wicked smile.
"So, you still have the hots for me, huh?"
The shock made me lose composure and I stopped swimming with the effect that my head came under water and I swallowed a whole lot of water. When I surfaced, I coughed convulsively and stared at her.
"W-wha-what do you mean?"
"Oh, Adam, don't pretend like you don't know what I'm talking about. You did a poor job at hiding your magnificent member up there on the beach. If you tell me you weren't the slightest aroused then I'll show you a liar!"
"But... but..."
She interrupted my stutter with a giggle.
"It's just like when we were kids. You must have realized that I saw you, didn't you?"
"Saw what?"
"Adam! Do you think that you were invisible when you spied at me?"
Exotic memories flashed before my inner vision. Images of Shesh in the shower, masturbating. Images of me, watching through the foggy window, beating furiously. No, I never suspected that she had seen me. Hell, for several years, I made it a sport to satisfy my carnal desires by masturbating while I watched her; sleeping, showering, masturbating, with boyfriends, with girlfriends. For I while I had even charged my friends top dollar for the opportunity to join me. The JTS Club. Jacking To Shesh.
I didn't know what to answer. What to say. I felt as though decades of bad conscience suddenly flushed over me and I started to feel very uncomfortable.
"Don't worry. If I had minded, I wouldn't have let you. Or your friends. Really, I don't think I would have dared to date some of the guys I did unless I had not known that you would be watching over me. And honestly, I don't think any girl can go untouched by the fact that someone very dear and much loved will go through so much trouble to be intimate with her, albeit from a distance. I felt proud of myself. Still do."
Her voice was calm enough, comforting enough, as to calm me down. But the words, the things she said. Really, it was outrageous. Or it would have been if everything she said was one hundred percent true. Including her observation of me on the beach. Nevertheless, I felt uneasy. Where was she going with all this?
"I want to be with you. Intimately."
Once uttered, the words weren't unexpected but filled me with awe nonetheless. Even though I had spent my entire youth fantasizing about this exact thing, it was just that: A fantasy. Never had I in my adult life even ventured the idea that my lewd and very much forbidden dreams would come true.
"There is a catch, though. There is something you will need to do."
She was starting to awaken my curiosity and I let a brief smile touch my lips.
"Ever since the first time, at least I think it was the first time, that you brought your friends and I could see you; oh yes, I saw you quite clearly Adam; masturbating, losing yourselves and finally ejaculating; do you know that all five of you ejaculated within ten seconds?; I have dreamt of seeing you, like that, again. Only much, much closer. Right by me. Targeting me."
Despite my recent mouthful of seawater, my mouth had gone completely dry.
"So... you mean that you...?"
"I mean that I want you to bring your friends, any friends. As many as you feel comfortable with. And you will stand around me, masturbating, allowing me to suck you, taking turns fucking me. A gang bang of gang bangs, so much more special because you will be there too."
She started swimming, slowly, still watching me. I stayed put, treading water, wondering if I was sleeping or delirious from too much drinks. She woke me from my thoughts with a giggle.
"Think about it", she shouted as she stepped out of the water, gathered her clothes and ran in her nude to her house.
Well, did I think about it? Sleepless, tossing and turning in bed; my wife even threatened to throw me out to sleep on the couch; I thought about the unreal suggestion from my sister. My darling sister Shesh. I knew she was wild, but this wild? Of course I couldn't. It was wrong. And bad. And cheating – I glanced at my sleeping wife. And so tempting. So impossible to not yearn for. So impossible to dismiss. The anguish would not let go, even after I had released my tension by jerking off outside, behind the house. The thought would not leave my mind, whatever I tried, however I reasoned.
By morning I had decided what to do. Breakfast was late; it was almost noon by the time I shambled into the kitchen. Shesh sat by the table and immediately caught my eyes. Her look left no doubt: The question lingered in her eyes and I was almost afraid that everyone else was able to tell the extreme tension. She demanded an answer.
Her eyes started to glisten with pure joy when I gave her a brief smile and an even briefer nod, terrified that anyone else in the kitchen would spot us and understand exactly what our silent communications were all about. Of course no one did.
Hugs, goodbyes, everyone in the family left the summer house and got back to their everyday lives.
