I must have looked a sight as my sister-in-law had just agreed to allow me to fuck her. Jo turned to walk into our cabin and I asked what she thought she was doing. Jo looked confused until another penny dropped and she realised that I wanted to fuck her outside in my cockpit. (A very apt name) Jo looked around and looked very, very nervous but I thought that if this was going to happen then I may as well get what I really wanted. I.E. to fuck my sister-in-law outdoors and in the traditional doggy style way.

Jo knew what I wanted and knelt down on the deck; I slipped her shorts off and pulled her top off too, what a sight! I knelt down behind her and asked if she was ready for a good fucking to which she replied, “Ok go on then, get it over with,” which put me off slightly as even old pervs like me like a little romance now and then! I started rubbing her cunt again and she started to get very wet again. I started rubbing my dick up and down along her cunt lips. She started moving back and forth in time with me and then slightly to my surprise shoved back at me and that was it, my dick slipped inside her all the way with one fast slippery movement! It felt absolutely great! My dick started to throb more quickly than usual from the sheer excitement of what was happening and Jo had her head turned to look at me smiling away with a big grin on her face. Jo asked if I was happy now and I just winked with lust filled eyes and said, “Oh yes.”

I don’t think there’s anything quite like the feeling of fucking a woman for the first time and Jo was no exception. Jo had the honour to be the first woman I had fucked during my 27 years of marriage and if I had to choose someone then it would have been her anyway.

As I was fucking Jo, she reached under and started to rub my balls, I love it when my wife does this and it usually makes me cum very quickly. That old feeling started to rise again and I mentioned that if she continued I’d be pumping cum inside her sooner than she had bargained for. Jo stopped moving for a second or two and then started again but with more movement. I guess she had calculated the risks of getting pregnant or some other thought but I honestly didn’t care anyway as I was enjoying the moment. I reached around and started rubbing Jo’s tits which she loved and when I tweaked her nipples she bucked even harder. It wasn’t long before I started pumping load after load of hot cum into my sister-in-law and she came as well. She started loudly oohing and arrghing and called me her bad, bad brother-in-law…which made me chuckle.

After we had both finished cumming I just waited and watched as she tried to move away to get cleaned up. I held her there and a superb thought crossed my mind. I reached out and grabbed my new Nokia N80 mobile phone (cell phone), which has
