This is a story of how Sebastian and Blaine became what each other needed without either of them realizing it or having been prepared for it. I swear it gets better after the first chapter. Disclaimer: I don't own anything!

With college getting closer and closer, Kurt and Blaine decide to spend as much time as they can together the summer before NYADA breaks them apart. However, when Kurt's half brother, Sebastian Smythe, shows up to stay with them for the holidays, they find their summer taking a very different direction.

Kurt is off to New York, Blaine is back at Dalton, and Sebastian is suspiciously quiet in the corner. Nothing is as easy as anyone wants it to be but maybe it will all be okay in the end. Starts off as Klaine. Eventual Seblaine.

[Sebastian/Blaine] Hunter makes a bet with Sebastian, his stepbrother, that he won't be able to take Blaine's virginity. If he loses, Hunter gets his Jaguar, if he wins, Sebastian gets Hunter. (CRUEL INTENTIONS AU)

It would just be a stereotypical summer fling, except for how it's not. Blaine and Sebastian reconnect during the summer following senior year, and their new found friendship develops into something neither of them is expecting. Seblaine. COMPLETE.
