Ooh, I love getting birthday prezzies, especially when they're all Nine-shaped and hot! Voyeurism is kind of a take-it-or-leave-it kink for me (not a squick at all, though), but it really, really works here--it shows just how urgently they need this, how powerfully affected they are by the aphrodesiacs and each other. Loved the reference to last year's present, too!
