What I am writing is a true story. I am writing about the first time I cheated on my wife… with my sister in law! To this day nobody knows – and it was the best sex I ever had. This also lead to the disintegration of my marriage but that will take sometime to explain. So let me go back to the beginning to explain.
It was a family barbeque. My wife and I were at my brother in laws house in the middle of summer. It was a beautiful day - hot and sweltering. It was over forty degrees Celsius and he wanted to have it at his new house - a fantastic two storey house, complete with pool and spa. What was more fantastic was the fact that I get to see my sister in law in her swimsuit. Now I should point out I love my wife and she is certainly no slouch – either in her appearance or in bed. In fact, she’s fantastic. But there is something about my sister in law (the fact she is forbidden fruit and the fact she is so fucking ripe she’s about to fall off the vine) that makes me rock hard.
Let me describe her. Her name is Sarah. She is about 5’3” – short. Like half way up to my chest short (I’m over six feet myself). She had long blond hair and deep brown eyes. She is in her early thirties. After having a child, she put on weight and that prompted her to work out more. She works out five days a week and is all about the Aitkin’s diet. Despite constant training, she has some weight on her but it just went to all the right places – her arse and tits (she is a double D). She has bounce and curves in all the ways you could want it. To complete the package, she goes to a solarium regularly to tan up. She has this deep bronze skin. It is such a turn on. She is a total MILF and could easily do porn (we did eventually make amateur porn but that’s another story for another time).
This was the first time I’d seen her out of her business attire as she worked as an account executive at some large firm. It was awesome. She wore this very flimsy two piece where you could see everything but she tried to cover her ass and hide her stomach. I could tell she was shy about her figure because all her friends who were there (who were also hot) were leaner. And I could tell that she felt insecure about it. However, I knew that her friends were jealous of her insanely huge and all natural breasts. I’d overheard them that very day.
My wife was playing with our niece, talking to her mother and her brother catching up on current events. The rest of the guys seemed content watching the cricket, lounging in the pool or talking and drinking beers. As for me, I couldn’t help but stare at Sarah the whole day. I watched her walk by the pool. I had my sunglasses on so she couldn’t see my eyes – and so my wife could see how they wandered. The eye candy today was plentiful but none as fine as my sister in law. I swear I think she knew I was watching too. I watched her as her hips swayed when she walked right by me and the way she lay back on the deck chair basking in the sun and champagne. I watched those nipple pierce that thin swimsuit as she laid back, her chest slowly rising with her relaxed breathing. Her legs crossed gave me a perfect view of this muscular, yet sexy thighs and round arse. I could tell from the way she sat that her arse was tight but had enough bounce to be perfect.
The friends of the family were outside, lying on deck chairs, drinking and talking and monitoring their own kids by the pool. The female friends were also similarly gorgeous. Peer pressure is not without its own merits I might add. These women were all friends and always tried to keep up with the Joneses. So they all worked out, tried fad diets. Some even talked about plastic surgery. What more would you expect from a bunch of thirty year old women?
I had gone inside to grab a beer and to abate the dull aching in my groin. I had to relieve myself or I was going to create a scene. It was at that precise moment I saw my sister in law bent over poking through the fridge.
I had an instant erection.
The swimsuit was riding the full length of her crack. Her top had half come down and in bending over I had a fantastic view of the full length of her shapely, tanned legs – ass, thighs, calves, as well as a good eyeful of her tits.
She heard me come in and asked if I wanted a beer. She wasn’t aware how close I was, let alone just how much her swimsuit was revealing. When I replied “Definitely” she did though. She noticed me checking her out and turned beet red immediately. She immediately covered her stomach and stood up, straightening herself out before squatting to get the beer from the fridge (it was less compromising).
I couldn’t help but tell her “Why did you cover your stomach? You know you look fine.”
She gave me a patronising look, as if to say ‘You don’t need to be nice just because we are in-laws.’
“Thank you Michael but I know I am.”
She looked outside wistfully at her friends.
“Don’t be looking at them, you know they’d kill to have your figure.”
She sighed “I’d kill to have theirs.”
