My wife used to go visit our daughters at college a couple of times a month. It took me a while to discover what they got up to together. I didn't like them doing it on my dime, so I gave them the freedom to do what they liked in the future. A flash BTB story, no sex.
A story in the Family betrayal and discovery Universe

Getting all hott and bothered with what she walked in on, Tiffany then helps her daughter get her twin brother back for what he has done and all of his other naughty secrets.
Last Night of Freedom = A Lifetime of Freedom, my ending to Catesby's Last Night of Freedom. - Catesby's resolution of the story was distasteful to me. The bride to be, on her last night of freedom sucks off a stripper, dances nude for half the town, and fucks the best man and groomsmen, doing things for all of them she'd never done with her fiancee. Such a darling bride to be... In this version, Behavior has consequences.
