Sister in Law Ch. 01

Not everything in this slowly developing story is real – some of it did really happen, some of it is fantasy that I wish would happen. Names have been changed.

Prologue

I knew that Jane, my future wife’s sister, had a crush on me since I met her for the very first time. Even after our wedding, she was always behaving provocatively in front of me, dressing in revealing clothes and when we all happened to stay around the pool, she took off her bikini top few times. My wife told me that her younger sister Jane was always sexually very charged and had lots of boyfriends. On the other hand, my wife lost her virginity with me when aged 28. Jane was not supermodel, but was attractive enough to get any boy salivating all over her, particularly over her well-developed boobs, that probably run in their family, and her long legs.

Over the last 20 years, she was always around and I always had a feeling that she still had the crush on me, but she stopped her sexually provocative behaviour, perhaps because she was always with her own partner whom she never married. Two kids and twenty years later, her figure was fuller but somehow she looked better and hotter than all those years ago. Rumour was that their sexual life was rather wild and that she was sexually rather demanding and dominant.

The big change came couple of months ago when her partner suddenly took off with both kids and left her with virtually nothing but her hot body. As good relatives, living alone in a large house, we offered her to stay temporarily with us. Little we knew that she would stay with us for much longer than we anticipated and what would happen between her and me.

At this stage, it is important to mention two things. For the sake of clarity, I am now 52, my wife is 48 and Jane, my sister in law, is 46. For my own defence, I have to say that in those twenty years of marriage, I have never been physically unfaithful to my wife, but due to my higher sexual needs and her gradually diminishing sexual drive, I have been more than active on-line and had a few satisfying on-line affairs. That changed one day…

The Start

It is a warm spring afternoon, my wife is in town shopping and Jane is getting first tan in the garden. After looking at her topless body for a while, I get hard on, so I go to my study and soon start SKYPE video session with my on-line mistress. It does not take long and I am stroking my dick while talking with her, not aware of anything else around me. As usually, she teases me a lot, being nude on screen in front of me, having her second orgasm and denying me my own. I am fully immersed in the session when she asks, “John, would you like to fuck my tits?” and I answer, “Yes, my dearest mistress, I’d love to fuck your beautiful tits.”

“John, you stupid idiot! Why would you pretend to fuck someone’s tits on-line if you can fuck these real tits?”

I freeze for a minute and then jump in my chair. Jane is standing next to me in her bikini bottom only, grinning at me and pinching her already hard nipples. I guess that she must have been listening for some time and am quickly thinking what to do next. She doesn’t give me much time though.

“Now, you little slave boy. Either you fuck my tits now, or I tell my sister what you are doing in your study all those evenings. I have been watching you for some time now and although I know she is not too keen on sex anymore, I am sure she would not appreciate knowing what you are doing to get your relief.”

“You must be crazy, sis. Do you really think I would fuck my sister in law?” I manage to mumble, my dick quickly softening.

“Wow, hold on to your horses, slave boy. I haven’t said fuck me; I’ve said fuck my tits,” she corrects me quickly.

Quickly closing SKYPE session, realising I will have lots to explain to my on-line mistress later on anyway, I continue, “And I am not your slave boy…”

“That’s enough,” says Jane sternly and slaps me across my face. “Aren’t my tits good enough for you or are you not man enough to do what you do on Internet also in the reality? I noticed you watching me earlier and I noticed the boner you got from it, so what’s your problem?”

“Jane, my problem is that you are my sister in law”, I stutter.

“That’s not a problem. That’s actually advantage, you silly. It is in the family and no one has to know. I had a huge crush on you since I saw you very first time. If I could, I would marry you instead of her… I always knew that you had higher sexual drive than her and she confided few times that you were not fully satisfied. I even think that she might know what you are doing here all those evenings…” she continues while grabbing my now soft dick and stroking it gently. Pulling my uncut skin over its head, she continues, “God, I love uncut dicks. You know, Robert was excellent in the bed, but I hated his cut dick… It is so unnatural. Your dick is so gorgeous… And much bigger than his was.”

With those words, my dick suddenly gets rock hard again and next thing I feel are Jane’s lips on it. Kneeling in front of me she starts licking and sucking on my dick for a while. She stops when she feels I am close to orgasm. “Let’s do the tit fucking now and then I will start training you properly, not like some on-line crazy bitch. Let’s go to my room,” she says with a wink and is pulling me by my dick to the room we have made so generously available to her.

When there, she lies on her backside and pulls me over her. “Now, fuck my tits and better enjoy it. After that, I will start training you and you may not be allowed to cum so easily, or you may need to show me how often you can cum, stud.” She guides my dick between her tits and holding them together with her hands I start bit hesitantly fucking them. My horniness soon overcomes my hesitation and it does not take long for me to shoot my load from between her tits towards her mouth. As soon as I do so, we hear a car pulling into our driveway. That must be my wife. We hastily clean ourselves with wet tissues and soon greet her in kitchen as if nothing just happened.
