You First: Only one thing stops sex with Justin being completely perfect for Luke. The timing. That isn't perfect. In fact, it really sucks-and not in the fun, fellatio related way. Having enjoyed more lovers than he can count or remember-Luke knows he's good at sex. There's no logical reason why the younger man should outlast him every single time they hook up. Time To Do: Rigby and Brennan have been best friends forever. Growing up and going away to university didn't alter that, nor did Brennan coming out of the closet to his straight best friend. But, when Brennan sees have sex with a man written on one of Rigby's old to do lists, it alters everything. When Brennan realises the man he's in love with might not be as straight as he always thought, their friendship changes beyond recognition.
