I always had a thing about my (3 altogether) wives’ sisters.

My first wife had an older sister who was married to a merchant seaman, he was away from home for up to 18 months sometimes.

They, the two sisters, were pretty close and, apparently, they would tell each other everything, also comparing sex lives. My wife confided to her sister that I was the best man she ever had in the sack, so my sister in law decided to find out about it for herself.

At the time I was a Police Officer, working shifts, days, nights, long rest periods, typically 4 days on, 4 days off, alternating between days (8am till 8pm), nights (6pm till 6am) and earlies (6am till 6pm); my wife used to work in a local Government Office, Monday to Friday from 9 till 5.

It all started in the summer of 1976, I was on my 4 days off, decided to go to the beach and enjoy the sun and sea, I returned home at around 1pm for some lunch and a siesta and found my SIL in the living room (she had the keys), I asked her if she had lunched yet to which she said she was famished, I told her I was going for a quick shower to wash off the salt and that I would have rustled up something to eat for the two of us.

I was in the shower shampooing my hair, eyes closed obviously, when I felt a hand circling my cock. At first I thought my wife had come home early from newcratos work, but when I felt a mouth sucking on my cock, I rinsed my eyes quickly, I liked to watch my wife suck me, and to my surprise there is my SIL having a bit of an hors d’ouvre!

Didn’t bother to dry off, took her to the bedroom and sixtynined with her and gave a couple of orgasms, then I buried my rampant cock in her pussy and fucked her silly.

She was squealing all the time as my cock was pistoning in and out of her cunt, I could feel the tip of my dick hitting the mouth of her uterus.

I turned her around, shoved her face in the pillow, grabbed her hips and lifted her arse off the mattress and started fucking her doggy style . . . she love it!

I was able to go deeper and when I felt my orgasm approach I pushed in as hard as I could and shot my spunk straight into the mouth of her womb, this triggered off the most violent orgasm I ever saw in a woman, she screamed like a banshee and was shaking all over.

I felt her cunt squeeze my cock, just like a hand on a cow’s adder, and milking me for all my worth.

I collapsed on top of her exhausted, covered in sweat, thoroughly satisfied.

As my cock started to shrink and plopped out of her cunt I rolled over onto my back, she did the same, but after a few minutes of me idly newcratos giriş playing with her nipples, she went down on me, took my cock in her mouth and did some fantastic resuscitating magic with her lips and I was again as hard as before.

She positioned herself on all four again, then scooped some of my cum out of her pussy, spread it on her sphincter and demanded that I fuck her arse.

At first I shove my cock in her cunt to lubricate it, then slowly but surely I started pressing onto her arsehole until the dome was passed her ring, gave her a few minutes to get used to the intrusion then I started to pump in and out very slowly and as I could feel her bowels opening up more I increased my speed.

All the while she was strumming her clitoris as my balls were slamming into her pussy. Then she went rigid, grabbed my ballsack and groaned loudly that she was cumming again.

I felt her arsehole tightening, but never stopped pumping, I wanted to fill her belly with my come again, eventually after a few more strokes I released my semen, spurt after spurt, not as much as the first time, but enough for her to feel it.

She was so impressed by the experience that when her husband was at sea and I was on my rest periods, if they happened to include Mondays to Fridays, she would turn up at my place at 9am and not leave until early afternoon.

It went on for about 4 years, until my brother in law got a job on terra ferma and they moved to a city over 200 miles from where I lived.

Never saw her again, as after I divorced my first wife, I left the Country.

Wife number 2, a divorcee with a 12 year old daughter, had two younger sisters, both single, both students, both as horny as hell; they made it very clear that they wanted something from their brother in law and they decided to seduce me together, that marriage ended when my stepdaughter came home early from school to find her aunts and her stepfather in a tangle of naked limbs, she told her mother and that was the end of that marriage, although I kept fucking her sisters for a few years after that, either one at the time or both together.

That ended when wife number 3, a mutual friend of the sisters, entered the scene.

She has a twin sister, identical, who also has a preference for her brother in law.

Within a month of being married I was banging her regularly and still do to date, although she got married herself eventually, we are very discreet, so it doesn’t happen more than a couple of times per month, and the funny thing is that on the days I fuck my SIL, when my wife and I go to bed it’s fireworks time.

Don’t get me wrong, I do not neglect my wife, we fuck each other stupid at least 4 times per week, but my libido goes into hyperdrive when I fuck her sister, and she (the wife) surely doesn’t miss out on anything.
