[B/S] Being caught, me and my sister's private lovemaking turned into an interesting threesome rather than a catastrophy. She joins us as often as she can now...
[B/S] Me and my sister work in the same office, and as often as we can, we sneak off to have sex. We almost got caught this time, but that just made it so much better...
[B/S] At least for the time being we don't have to worry about my sister getting caught sneaking into my room at night. I don't think we're gonna get a lot of sleep these coming days...
[B/S] My crazy sister has a goal for me to fuck her in every room in the house, and she doesn't care what time of day it is or if anyone else is home. It's a miracle nobody's caught us yet...
[S/S] Now that she had been caught redhanded with her sister's panties, Charlotte figured she might as well come clean about her incestuous fantasies...
Your sister and her boyfriend came home unexpectedly and caught you perusing her panty drawer. He beat the shit out of you, and watching got her so turned on she gave it up to him right then and there. "Serves you right, you perv!"
