Sister In Law

I got out of the Army and was staying with my mom for a while and so was my youngest brother and his new wife who was both only 17 and 16 years old my brother was 17 and his wife was 16. Anyway I had been there about two months and I had done some light flirting with his wife nothing serious more joking around than anything. Fast forward 3 years later and he and her had moved in with my older sister for some reason I don’t know why but anyway I had my own place. He wasn’t working and I was off work for vacation and decided I wanted to go fishing and went over to their place to see if he wanted to go with me but he wasn’t home but my sister asked me where I was going so if he came back and wanted to he could come down there and I told her. I’d been there for a while and I heard someone coming and thought it was my brother but when I seen who it was it was my sister and sister in law and they said that they wanted to go swimming, I said well that’s fine because the fish aren’t biting here so I’m going to go move to a different place and my sister in law said you guys used to talk about having a place where you would come down here and party where’s that at so I told her that I was going right past it and if she wanted to she could walk with me because it wasn’t very far. So she told my sister that she would be back in a little bit and we started walking up to the little road that went around the lake. We got to the road and was walking and I said Janet when are you going to let me see something she said what do you want to see these and pulled up her bikini top so her boobs was showing I was like oh shit I didn’t expect you to do that then she reached down and pulled her bikini bottoms to the side enough to show her nicely trimmed pussy( that was before all the girls started shaving) she said you can see it but you can’t tell anyone and you can’t touch it. Well we walked on down to the place where we used to party and I pointed it out and showed her then I thought I’d try to kiss her and see what happened and she let me. We kept kissing and then I was playing with her pussy and she kept pushing my hand away saying we shouldn’t do this but she never tried leaving so I kept trying. I finally got my fingers under her bikini bottom and she moaned as I slipped a finger inside her I said let’s lay down you can lay on top of me she said okay but don’t go any farther than what we are doing now I agreed and we laid down we was kissing and she was grinding on me and I was fingering her and slipping my shorts down with my other hand at the same time I finally got them down enough that my cock was out and as soon as she started to cum on my fingers I pulled her bikini bottoms to the side enough to push it inside her wet pussy and she moaned oh yes fuck me fuck me good we fucked on the side of the lake for about 10 or 15 minutes and I filled her with cum with her moaning and screaming. We finally got finished and I told her that I didn’t think I wanted to fish anymore and because they wasn’t biting anyway. We went back to where my sister was and she was swimming around in the lake she swam up close enough to where we could talk and said I thought you were going to go fishing and then kind of laughed. I think she knew exactly what we had been doing but if she didn’t she figured it out later because I went back over to their place and me and my sister in law went to her bedroom and made a lot of noise….lol
