They arenít just brother and sister. They are also fraternal twins.
This story could end up anywhere from Light Human to Extreme, depending on what is decided as we build a story. Iíd be happy to play either the male or female twin in this story, whichever youíre more comfortable with.
Sara and Jesse (both names are place holders) are both married and living in separate towns. They visit occasionally, but always with their respective spouses. But on their 10th Anniversary High School Reunion, the spouses are tied up and they decide to travel together to their hometown for their reunion.
Both siblings have friends theyíd like to reconnect with before the actual reunion, so they decide to stay for the entire weekend. The first night in the hotel is uneventful, with both siblings in the lounge and in the company of their friends from school.
Then comes the evening of the reunion. Everything goes as planned and both have a good time, reconnecting with high school friends and reminiscing. They drink a little too much maybe, and at the end of the evening they decide to buy a bottle of wine and go back to the hotel to talk before they turn in to rest up for the drive home tomorrow.
Maybe it was only the alcohol, and maybe not, but Sara and Jesse end up a lot closer than they planned on, and Sarah ends up spending the night in Jesseís room.
The next morning, both siblings are horrified when they realize what they have done, and they both decide that it is best not talked about, so they donít. Most of the trip home is spent in uneasy silence.
But when they return to their spouses, one of the siblings (we can decide which one) canít stop obsessing over that night in the hotel, and finally, breaks down and calls their sibling and asks to meet with them. And that meeting is where the true seduction begins, and their relationship goes far beyond the drunken coupling of their first night together.
The elements Iíve presented here, plus whatever we decide upon, should be enough for a varied story landscape, as well as a good sexual story between siblings. Iíd like to develop both over the course of the story.
