My life seems to be so mixed up but so much more exciting since my sister-in-law, Jo, allowed me to fuck her for the first time since she married my wife’s brother 12 years ago and has the honour of being the first woman I’ve fucked since marrying my wife 27 years ago.

I know some of you will think the worst of me and my sister-in-law and I’m sorry if you do as we don’t want anyone to get hurt. This account is a little long but when you’re 46 and start fucking a younger woman of 31 you want to remember every last detail.

Jo is 31, 5’9” with a typical hourglass figure that looks good in anything. She has lovely tits with superb nipples and is shaven with lovely long, long legs. Jo’s always been a shy girl and has had little confidence until recently. I must explain that I am happily married to my wonderful wife of 27 years and I’m a typical English bloke who’s starting to go bald!

I have always, always looked at Jo and fantasised about fucking her or at least getting her to give me a blow job but hadn’t dared to take things further than fantasising in my own pervy mind. Do all middle aged guys think like me? I am, after all, 46 years old.

Over the years I have seen a few glimpses of her tits and on one famous occasion when we were camping in Wales, she bent down next to my camping chair to sort something out in a bag and I got to see her beautiful tits for quite a while until she realised what I was doing and playfully slapped me for “perving” at them. Well, she should have worn a bra! She is great fun when she’s had a glass or two of wine and really relaxes and can get very flirty when I start asking her to flash me again with her tits! Her husband Steve is more like a brother to me and we get along fine but he does get a little jealous if Jo and I go too far when we drink and start flirting. My wife gets pretty jealous too, it must be a family trait. So far we have never gone further as I’d hate to spoil things within our family but I have always had the thought that Jo is not directly related to me and in that case was a woman that I wanted to fuck. To complete my description of our situation I just want to add that Jo has a very innocent way about her and does not get all of my suggestive/pervy remarks straight away.

So, how did I end up fucking her? Well last year I bought a canal cruiser (cabin cruiser to any non UK readers) and had it transported to our local canal mooring. Jo was really into helping tidy the boat up and all of us enjoyed working on my boat. My wife and I are really into the canal scene and love traveling around on the UK canals. Jo, more than her husband Steve, took to our newfound boating fun and suggested that whenever we go down to the boat that we should call them and see if they are free to come with us. Their idea was to gain enough experience to one day take a holiday in it without us. One Saturday evening I called Steve to see if they wanted to come down to the boat for the day on the following Wednesday, which is my
