Let's think of this as my diary. I've never kept one in all my life, but maybe some things that happened to me are worth writing down, so this is what I've decided to do here. My Name is Kai. I've been married for just about 4 years now, and very happily I might add. My wife and I are very outgoing. We have done a couple of things in our marriage which, maybe, I will write down some other time. For now, let me tell you about last night, the night we seduced my little sister...
I've had that thing about my baby sister for about 2 years now. She is cute and very sexy in her own way. Ask me if she's pretty, and you'd get a big confirmation on that from me. She might not have the perfect body, and some people would call her a little chubby, but she knows how to make the best of what she has, and that's very much enough for me.
Franzi, my wife, is perfect. She is at 25 a year younger than me. She is a natural blonde, 5"6' with nice b-cup breasts. She is bisexual, having discovered that throughout our marriage.
I myself am 6"3' with a very slender body. I have dark short hair.
So where do I start now... Let's start at the beginning, and let's fill in some little details first.
Franzi and I moved to the town we life in now a couple of years ago. We like it here. We both like the opportunities a big city has to offer. Nearly 2 years ago my little sister moved here, too. She does not life with us but with her godmother. We helped her get set up here, and she comes over every other week or so. We used to go to the movies together, all three of us or sometimes just my sister and me.
One year ago we went to a big thermal bath together. Franzi and I love to go to saunas and stuff, and we had told Jasmin so. Jasmin? Oh yes, that's my sister. One day she decided to come with us. We had told her about being naked in a sauna, and she said that would be no problem for her. So that afternoon we were pretty eager about seeing her naked. My wife loves the look of naked women, and I usually don't complain when being offered such an opportunity myself. When stripping down in the changing room we were intrigued with Jasmin's looks. Her long brown hair cascaded about here naked shoulders, down to her c-cup breasts, which were sagging just a little. She had a nice round butt, and she was shaven bare, just like Franzi and me. She looked awesome. That was the time we started fantasizing about her...
Over the next year we went to the thermal bath a couple of times. We enjoyed ourselves quite a lot, having fun when swimming naked or sweating together. We also met a couple of times to play games, having taught her to play poker some time ago. Soon we got bolder and suggested to play strip poker, which she happily did. We all liked to see each other naked, it seemed, and it was fun all of the times.
So what changed things into seducing her after all that, you might ask? Good Question. I don't know, things just changed.
We had talked about sexual things on some occasions before, and we knew that she owned a small vibrator. So when her birthday neared, we agreed to get her something new. Franzi told her. So on the day of her birthday Franzi and Jasmin went to an adult store together. Franzi told her she could pick one thing, whichever she wanted, on the condition that she had to show us when she used it first. Jasmin agreed, with a naughty smile on her face, and went on searching the shop for something that would suit her. About half an hour later she had picked up a dildo, about 5 inches long and quite thick.
Franzi bought it for her, and we agreed to meet a couple of days later. Jasmin assured us she wouldn't back down from this, and she did it smiling.
